Meliodas/Plot

Introduction arc
Meliodas is first seen in the Boar Hat, serving his disgusting meals, and then ordering Hawk, a talking pig, to clean up the vomit of his customers. Moments later, the infamous Rust Knight enters the bar, scaring all the customers who believed him to be one of the "Seven Deadly Sins", and collapses moments later, which reveals him to be a female. The woman soon wakes up, is offered food and questioned as to what she was doing in an armor. As she begins explaining that she is searching for the "Seven Deadly Sins", a few knights, having been informed by the villagers of the Rust Knight, demand that Meliodas and him come out. The young man and Hawk do so quickly, and anger one of the knights by the latter's pretending to be the Holy Knight. As the woman when flees towards the woods, they notice her and go in her chase. She is quickly rescued by Hawk and Meliodas, who ask for her to continue her answer. She then explains that she was searching for the "Seven Deadly Sins" in order to stop the Holy Knights, who, a few days ago, had orchestrated a coup d'etat, and had taken control of the kingdom; she also reveals who the Seven Deadly Sins are.

Abruptly, the cliff the three are standing on is cut off by Twigo. Meliodas, however, rescues all of them. After he does so, Twigo notices the woman's earring, and then realizes her true identity as Elizabeth, the third princess kingdom. When the knight attacks them, Meliodas rescues her; he does so again when she gives up her life in an attempt to not involve Meliodas in her matters. Smiling, Meliodas reveals his name, and thus, his identity. As Twigo attacks them again, Meliodas repels the attack, and, declaring his title as the "Sin of Wrath", then again repels Twigo's attack with his broken sword, thus defeating him. Meliodas, explaining that he is also searching for the other Deadly Sins, offers Elizabeth to accompany him on his journey, an offer she tearfully accepts.

Hired as a waitress of the Boar Hat, Elizabeth is given a new set of clothes by Meliodas. She then questions him as to the crime he had committed and doubts whether he is an actual criminal. He initially jokes about the reason, but, in the end, he does not properly answer her. Meliodas, Elizabeth, and Hawk soon reach Bernia, a village famous for its ale made from the village's famous river; they, however, they find the river to be completely dried. Upon finding a large crowd of men trying to pull out a sword, the three discover that the previous day, a Holy Knight had sealed the river's underground water supply, preventing the creation of Bernia ale, the town's primary sources of income. While the men unsuccessfully try to pull out the sword, a boy named Mead starts boasting about his friend from the Seven Deadly Sins, his comments only served to further enrage the villagers, who begin blaming Mead for their crisis.

Meliodas takes Mead to Boar Hat and feeds him in return for information on his "friend" from the Seven Deadly Sins. This, however, turns out to be a hoax. Elizabeth, having learned that Mead was the one who angered the Holy Knight, manages to have him tell her the reason he did so, by narrating him an episode of her childhood. The four then watch from the window as two knights inform the villagers that if the sword is not removed by that day, taxes will be multiplied by ten times. As all the men, now including Mead, try their best to remove the sword, Meliodas, after drinking some Bernia ale, removes the sword with ease, in order to pay for his drink, which causes the dammed water to gush up like a fountain.

Sometime later, Meliodas asks Hawk and Elizabeth to buy some herbs and fruits with the silver coins he hands them, for Elizabeth to gain some experience, since she, being a princess, has never seen a silver coin before, having used only gold ones. He also informs them that the day's main dish will be the Dusk Bison that has been acting as a pest and destroying people's farms. When the two return empty-handed, and explain how they lost the items they bought, Meliodas hilariously expresses his irritation.

That evening, as the villagers celebrate in Boar Hat, Meliodas instructs Elizabeth to take her job lightly, since it was her first time being a waitress. During the celebration, Meliodas senses Gilthunder, the aforementioned Holy Knight's, spear heading for the village, and goes out. Outside, he finds Elizabeth, who, having made many mistakes while waitressing, had run outside while crying. Encouraging Elizabeth, Meliodas stops the spear, but only after being pushed back a large distance. He then sends it back at Gilthunder, which leads to the destruction of Fort Solgales, and the Holy Knight's realization that the Seven Deadly Sins are still alive. The next morning, Meliodas suggests that they should leave the village immediately and continue their journey, since it would be more dangerous for the villagers if they stay there.

Forest of White Dreams arc
Having learned of even Holy Knights avoiding the Forest of White Dreams in Bernia, the group of three travel there, speculating that there might be a Deadly Sin hiding inside. After walking in the forest for more than three hours, and losing their sense of direction, the three find multiple copies of Hawk, all claiming to be the real one. Meliodas, mercilessly defeats all the copies, including the real one, but then discovers similar copies of Elizabeth. Each of them declares to do anything that they are real, and Meliodas then instructs them to jump as high as they could. All of them, except the real one, do so, since Elizabeth's panties had been stolen by Meliodas before, and she was embarrassed to jump. Defeated, the copies show themselves as Prankster Imps, and retreat towards a giant girl, who is revealed to be Diane, the Serpent's Sin of Envy. They then apologize to her for allowing a Holy Knight to come through, having believed Meliodas to be one.

Immediately after being woken, Diane lifts Meliodas with her hand, only to cuddle him and cry tears of joy as soon as she realizes his identity. When Elizabeth introduces herself to Diane as traveling with Meliodas, Diane jumps to the conclusion that she and Meliodas are a couple, and throws a tantrum. Meliodas, after calming her down, explains to her the reason he and Elizabeth were traveling together. He then proceeds to begin a discussion about the day, ten years ago, informing her that he has almost no memories of the day, much to Diane surprise. Meliodas narrates the only memories he has, which end with one of the Deadly Sins apologizing to him. The narration leads Elizabeth to speculate the existence of a traitor, and Diane, to declare that she will help Meliodas. Few brief moments later, Hawk notices a gigantic thundercloud in the sky. A lightning bolt from it then binds all of them and the assailant is shown to be Gilthunder.

As Gilthunder walks towards them, Elizabeth explains Gilthunder's identity, and that he was a brother figure to her, but soon realizes his intentions. After Gilthunder leads her away, ending her interruption, he, pointing his sword at Meliodas' neck, expresses his desire to avenge his father, and also to prove that he has surpassed him. Meliodas and Diane easily break Gilthunder's immobilization spell themselves, with Meliodas instructing Diane not to interfere. Gilthunder attacks first with a lightning bolt; the Sin of Wrath repels the spell, only for the Holy Knight to dodge and move behind the latter, slashing him from behind and causing him to fall to the ground. Meliodas, seemingly in his last moments, asks for the whereabouts of the other Deadly Sins as his last words. Gilthunder answers to him the locations of Fox's Sin of Greed Ban and the Grizzly's Sin of Sloth King, the former being imprisoned in the Baste Dungeon, and the latter having perished in the Capital of the Dead. As he is told so, Meliodas quickly jumps back up, revealing that he had tricked Gilthunder into revealing the information.

The Holy Knight refuses to stop their battle and repeatedly attacks Meliodas very quickly. He continues his attacks but is suddenly lifted by Diane with a hand. Gilthunder's attempts at escaping her grasp unsuccessful, Meliodas watches as Diane flings him out of the forest. Meliodas later decides to head toward the Baste Dungeon, leading Elizabeth to object his decision, citing his grave wound as an impediment. Though assuring her that he is alright, Meliodas soon collapses.

Baste Dungeon arc
Meliodas is taken to Dalmary, a town near the Baste Dungeon, where he is treated by Dana. Later, Dana has Meliodas drink some medicine he prepared himself, which is later revealed to have been a deadly poison, with Dana being revealed to have made a deal with Golgius. When the Holy Knight appears, and then tries to grab Meliodas' broken sword. Meliodas, however, is shown to still be alive, but with his eyes being mysteriously colored black, and with a strange black colored symbol on his forehead. As Golgius tries to pull the sword, Meliodas declares that he would not let go of it even if he dies and that this was the only way he could atone for his sins, while releasing an aura which frightens Golgius into fleeing.

Meliodas seems to have returned to normalcy soon after this. When Elizabeth then questions him as to his wound, it is revealed to have already healed, something that puzzles even him. The three then go in Golgius' chase, soon finding him due to Hawk's sense of smell. Much to their surprise, Golgius immediately surrenders; Meliodas, however, notices the blades that Golgius discreetly threw, and blocks them. Soon after, Dana also finds Golgius and is killed in order to censor the two's deal, with Elizabeth, worried, running towards the doctor. As Golgius disappears after his attack is blocked by Meliodas, he confirms that his ability is teleportation. The three then escape, and soon enter an abandoned building, where Meliodas slashes his sword in the air toward the door, comically claiming that it was a magic spell. They wait inside when Golgius suddenly appears behind Meliodas, but falls for the Sin's trap - a cut on the floor of the entrance - and falls down to the bottom of the building. There, the Deadly Sin reveals that Golgius' ability is actually transparency, and how he discovered so. He then attacks his opponent at point-blank range.

Meliodas then questions Golgius about the person who had ordered him to bring the broken sword and Elizabeth, only for Golgius to escape due to a distraction. After he leaves, Elizabeth goes towards the dying Dana, who apologizes, explaining that he had only wanted to rescue his daughter and, lamenting his inability, dies. Elizabeth blames herself for this since if she had not found Meliodas, he would not have been put in danger, and Dana would not have died. Meliodas, in response, questions, whether her resolve to protect the kingdom's citizens, was as weak, declaring that he would fulfill his promise even if she were to die. He proceeds to inform her of the inheritance of the principles of an individual. Not long after, Meliodas and Hawk head for Baste, leaving Elizabeth in Dalmary due to the dangers. She, however, joins the two herself and, encouraged by Meliodas' speech, responds that though she has no power, she will continue to fight for the people even if he were to die. As they walk, they encounter Diane, who seems to have no memories of defeating Friesia's insects and leaving for Baste.

Diane tries to recollect the events, and Meliodas then determines to rescue as Sennett was their main priority. Suddenly, he finds Diane to be attacking him; immediately realizing that she is under an illusion, he flees along with Elizabeth and Hawk, and, upon finding two civilians, walking nearby, takes them along. As the three, and the two frightened civilians, hide, Meliodas also falls under Ruin's hypnosis when he tries to look at Diane, which makes him see Ruin in her place the same way she sees Ruin in his. Thinking he is attacking Ruin, he attacks Diane, which begins their battle. The battle is only stopped after Elizabeth manages to remove the origin of Ruin's illusion - the bell on his staff. He, enraged by this, charges towards the heavily injured Elizabeth, but is stopped by Meliodas, the illusion now having stopped.

Meliodas tells the unconscious Elizabeth that he accepts her resolution, as Ruin attacks him. Ruin expresses his disbelief at the kingdom being frightened of a "small child". After two of Meliodas' punches, Ruin, exclaims that his soft fist would not even scratch his armor, and suggests that he draw his sword. When Meliodas does not, Ruin attacks with a barrage of punches; though they possess great power, Meliodas remains unscathed and breaks Ruin's armor. He is unfazed when Ruin then hardens his abdominal muscles as his armor and proceeds to easily defeat him with a punch that plunges his arm into the Holy Knight's stomach. Later, when Diane, Meliodas, Hawk, and Elizabeth, who is sleeping inside Diane's bag, enter the dungeon, they encounter Sennett fleeing from Ban, as he appears soon behind her. Initially appearing very tense despite their reunion after 10 years, Ban and Meliodas are shown to get along very well, and greet each other with multiple high-fives at great speed. They then energetically start arm wrestling, the mere force of which begins destroying Baste. Both argue on their score on arm wrestling as the dungeon continues collapses. After it is fully destroyed, Ban states that he is glad to meet Meliodas again.

The group, Ban, and the people who were imprisoned in Baste, including Sennett, return to Dalmary. Soon after, Meliodas enters Dana's house but is surprised to discover that Dana is mysteriously alive. The doctor reveals that he knows nothing about this strange phenomenon, and showing the deep wound to have neatly healed, points out that it was similar to Meliodas' sword wound, which had also healed and left a scar in a similar way. Sennett then interrupts, questioning the reason her father was nearly killed and she, imprisoned. When he answers, she tells him that poisoning Meliodas was not his fault, but the Deadly Sins' own fault, since the group were criminals. Dana, however, argues against, explaining that Meliodas never blamed him, and even selflessly rescued her. He then offers a token of his gratitude by a meal. At night, during the party, Ban is formally introduced to the bedridden Elizabeth. Not long after, Sennett notices crossing shooting starts in the sky and brings them to everyone's attention.

Capital of the Dead arc
The characters begin their journey towards the Capital of the Dead from Dalmary Town. Meliodas decides to not head towards the Kingdom's capital yet, but instead, they move further away. On the road, they are confronted by two Holy Knight apprentices, with one known as Andre. Meliodas initially deceives them by advertising their Boar Hat bar with Diane and Elizabeth being the two attractive waitresses. However, after Diane released her appreciations of being praised by hugging him, the knights realize that they are the Seven Deadly Sins. Suddenly, a Black Hound appears and quickly defeats the two knights. When Ban attempts to scare the creature, it grew bigger as a result of feeling threatened. In the end, Meliodas intimidates the Black Hound with his Broken Blade's powers.

Gradually, the characters arrive at a lonely village that is said to be closet to the Capital of the Dead. Meliodas decides to open the Boar Hat bar in order to earn some money for food and begin giving everyone roles. When Ban begins complaining about working, he reveals that he return Sennett her dagger, so they could not sell it for money. When everyone was about to begin working, they discover that Ban had escaped. At the Boar Hat, Meliodas tells a past story about Ban and King and states that they are an unlikely dynamic duo.

Meliodas and the rest begin searching for Ban and discover his fighting against King. He suddenly appears and interrupts the battle by knocking Ban on the head with a cup. Meliodas and Diane then easily notice King, although he quickly runs away. Back at the Boar Hat, Ban cooks a delicious meal and requests for the location of the Capital of the Dead from Ellen and her brother Luigi, who reveals that King has also requested the same thing.

The discussion about the Capital of the Dead continues and the characters are told that the village is actually the entrance. However, you cannot go there just because you desire to. Out of the blue, Ellen recites a riddle she always heard from her neighbor, a priceless memory shared with the deceased will open the path to the capital. The characters then begin searching for a method to enter the Capital of the Dead. Realizing that there are flowers on the ground, Hawk begins sniffing them when a sudden breeze wafted all of the petals. When the characters open their eyes, they discover that they arrived at the Capital of the Dead.

Ban suddenly runs away, leading Meliodas and the rest to follow after him. Whilst attempting to follow, they is blown away by an explosive strike from Guila but easily recovers. He then suddenly encounter the Holy Knight Guila who killed herself to enter the Capital of the Dead. She begins attacking when Meliodas immediately tells Hawk to run away with Elizabeth after realizing how dangerous she was. Meliodas catches Diane who has also blown away the same way. The two then begins attacking the Holy Knight together, before Guila provokes Meliodas to use his sword. In response, Meliodas draws his broken blade and utilizes Full Counter against Guila, who reveals that she knows the ability.

Meliodas and Diane were still fighting Guila, but she was too strong and Guila was about to use the power that she called Explosion, but she was stopped by Ban using his power, Snatch, but Guila used her Explosion to stop Ban ability. As the battle continues, the Sins were losing but then King arrives and offers to help them. Guila used her power once again to kill the Sins but King blocks that attack and decided to fight her alone which the other Sins agree to and sit down and watch the fight.

Meliodas and the other watch as King defeated Guila with ease, but then she came out of the rubble and was about to attack King but Meliodas blocks the attack and sent her back to the living world. The Sins bodies were starting to disappearing and are about to go back to the living world. When they are back, they saw that Guila was there, but still in a near death state and had not returned yet. Ban said that they should kill her but Meliodas had an idea to do something to her. The Sins later left the village to continue their journey. King asks Meliodas who Elizabeth is but as always, he teased her, but then told him she is the princess which surprised King and decided to go to his fat form to show respect to Elizabeth but Meliodas does not notice the differences but the clothes. When King asks what happen to his Sacred Treasure, which Meliodas says that he sold it.

Vaizel Fight Festival arc
Not long after, Meliodas questions King the current status of the kingdom. Later, at night, inside the Boar Hat, Elizabeth somberly remembers her childhood; her spirits are lifted when Meliodas reassuring her that her family will be rescued soon. The next day, he decides their next destination be Byron, and then questions King about his statements the previous day. King, in response, reveals Guila was a mere low-rank apprentice the day before she fought them, explains the mysterious "New Generation". Meliodas, and three others, then enter Byron, where they also discover a new wanted poster for Elizabeth. All the residents unsuccessfully try to chase the criminals in order to hand them to the Holy Knights. After the four escape to a tower, Meliodas and King leave Elizabeth and Hawk to gather information, upon the princess' own urging.

In the evening, Hawk tearfully explains to Meliodas and King about Elizabeth's capture by Griamore and Veronica. Though King suggests to formulate a plan, Meliodas, enraged, states that they are going then. King, upon finding the inn where Elizabeth is being held, uses his telekinetic abilities to topple a cup on the table. While Griamore reaches out for it, creating a distraction, Meliodas enters the room, and very quickly defeats Griamore in an ambush. Later, Elizabeth thanks Meliodas, and, as the two walk, Meliodas' shadow is shown as the silhouette of a giant monster. The next day, near the town of Vaizel, Meliodas explains about the town hosting an annual flea market, and about his speculations of a sacred treasure being sold there. Meliodas, Ban, King and Hawk head to the town, and there, are directed, by an alcoholic, elderly man, to the Fight Festival, whose rewards include Gideon, Diane's sacred treasure. Sometime later, after a brief skirmish with Taizoo, Meliodas, Ban, and the unwitting King, along with the other contestants, gather at the fighting ring for the preliminary round.

During the preliminary, Meliodas is among the handful of combatants who overwhelm the rest and later qualify for the main tournaments. Afterward, Meliodas is assigned to battle Ban in the first round. Ban had entered himself, Meliodas and King as "Baan", "Meliodafu", and "Old Fart", respectively. Howzer almost recognizes the two but dismisses them as the Deadly Sins because of their obvious aliases, due to his naivety. When the first battle between Matrona and Griamore begins, Meliodas, along with others, ponders whether the former is Elizabeth when she reveals her similar appearance to the princess. After Matrona wins, her hat falls down, revealing her facial similarities to Diane's. She skips toward the three Sins but is only greeted with Meliodas' question as to her identity, which angers her and prompts her to punch him and storm off. She then answers to King's questions, explaining how she and Elizabeth were shrunk.

Diane merrily states that she had wanted to surprise Meliodas, and jumps on him, expressing her elation at being held by him. She then asks Meliodas to grope her, as to how he often gropes Elizabeth. When she becomes upset at his refusals, Meliodas comforts her, explaining that he cannot act so to an important individual as her. After King and Cain's battle, Meliodas and Ban ready themselves for their battle, which is the final one in the First Round. As the battle begins, Meliodas compares the circumstances they are in currently to his and Ban's first meeting, and punches him. Regaining his balance, Ban exchanges several attacks with his opponent. One of Meliodas' punches sends Ban crashing into the ring, even breaking the Great Vaizel Rock. Soon, when Meliodas attacks Ban again, he himself falls down to his knees, Ban having used his ability, "Snatch".

When Meliodas tries to retaliate, he seems to have weakened. King explains that this is since Snatch enables Ban to "rob" physical objects and also physical abilities such as speed and stamina; Meliodas is losing his stamina. As Ban overwhelms Meliodas, he then also starts "robbing" Meliodas' raw strength. After sometime, Ban decides to now rob all of Meliodas' abilities together, as otherwise, he would not be able to end the battle. While Meliodas attacks Ban, the latter steals the former's abilities, and manages to completely do so before he is defeated. As he stands over Meliodas, Ban allows him to give up, an offer Meliodas immediately refuses. Diane theorizes that Meliodas is baiting Ban into delivering the punch, and will reflect the blow back with Full Counter. King quickly refutes this, explaining that Full Counter can only reflect "power" attacks, and not indirect attacks like Ban's.

Despite Elizabeth's pleading, Ban punches Meliodas. In the midst of the resulting debris, Meliodas, who now mysteriously has a strange black colored mark on his forehead, and with his eyes colored black, similar to how he was when Golgius had attacked him previously, crushes Ban's hand, and proceeds to defeat him. After Diane's battle against Howzer is announced, Diane hurriedly hands Meliodas a shrunken Elizabeth, before leaving for the battle; the Sin of Wrath smirks perversely at the sight of a shrunken and naked Elizabeth. While Diane enters the fighting ring, Meliodas teases Elizabeth. The princess then tries to question Meliodas as to why he acts perversely towards her, believing that this is since he does not consider her to be important; this is why she has been dejected for a while. He, however, does not hear her response, leading her to dismiss it, and mentally resolved to believe in him. She then proceeds to then have him promise her that he will not battle recklessly, as he did with Ban; Meliodas, however, mentally adds that he will only do so when she is nearby, hilariously.

After Diane's battle, Cain and Meliodas enter the ring for their battle. After a brief conversation on whether Cain entering the Fight Festival was a coincidence, Cain, questions him whether he is Meliodas' son, and is greatly surprised upon learning that his opponent is Meliodas himself. Initially disbelieving, Cain, after accepting the fact, attacks Meliodas, and jumps back, declaring that he cannot forgive Meliodas, who betrayed the kingdom, its people, and his most important person. Meliodas then recognizes the symbol on Cain's shirt as Danafor's crest. Questioning Meliodas as to why he destroyed the kingdom, and killed its citizens and Liz, Cain attacks him with a fireball; Meliodas does not evade them. Cain, finally ending his attacks, releases a giant fireball. Meliodas, answering the series of questions, states that he had tried to protect Danafor, but failed and that this failure is his sin. Facing his palm towards the attack, Meliodas completely disperses the attack. Cain recognizes this technique as "Counter Vanish", the use of which has convinced Cain of Meliodas' identity.

Meliodas replies that he has come to remember Cain as well, and reaffirms Cain of his earlier statement. Cain delighted that the rumors about Meliodas' responsibility for the destruction of Danafor are false and glad to be rid of suspicions, forfeits his match. Finally, for the final battle in the tournament between Meliodas and Diane, or Matrona, both fighters enter the ring. Diane suggests to end their battle soon since they have already won their target: Gideon. However, they are then interrupted by three women, who cheer Meliodas in a very erotic manner. Diane, enraged at Meliodas' obliviousness on this, punches him as their battle begins; Ban had paid the three women to cheer erotically for Meliodas to anger Diane and have her battle Meliodas seriously. Meliodas realizes Ban's scheme and exchanges a barrage of powerful attacks when Diane when she refuses to believe that she has misunderstood, with one of the attacks nearly pushing him out of the ring. Regaining his balance, Meliodas then jumps, and tries to attack from above.

Diane, however, stops the punch and sending him flying, all the while slowly returning to her usual size. As Diane grows, Meliodas escapes all of Diane's repeated punches by slipping through the cracks their battle has created on the ring. As they battle, the audience expresses its disapproval and dislike at the low seriousness of the battle. In response, Meliodas stops fighting, and declares his identity as a Deadly Sin, and also that the Sins will be capturing Vaizel. After King and Ban also enter the ring, Meliodas continues, threatening the civilians to leave Vaizel in one minute, lest I massacred. A few moments afterwards, gigantic, and explosive flares rain down on Vaizel. As the assailants, Guila, Jericho, and another Holy Knight, land, the citizens are intimidated by Ban into fleeing, which makes Elizabeth realize the motive of the Sins' actions: they had forced the civilians to leave, so that they would not be involved in the battle against the Holy Knights. Meliodas, noting on the Holy Knights' strength, instructs King, Diane and Ban to separate.

Soon afterward, Guila finds Meliodas. He accepts to fight her, but she retorts, boasting her increased abilities, and then releases several flares, which stop midway. When he jumps to destroy the flares, one of them suddenly explodes, which triggers multiple explosions. After the gigantic inferno settles, Meliodas, heavily injured, falls from a height. After Jericho also defeats Ban, King confronts the two Holy Knights, and defeats them with great ease; he then hands Elizabeth and Hawk the responsibility of watching over the two defeated Sins. Hiding behind a building, Elizabeth hangs the pendant that Veronica gave her earlier around the unconscious Meliodas' neck, as Veronica and Griamore find her and Hawk. Veronica notices the pendant on Meliodas' neck, and then grabs Elizabeth's hand, trying to bring Elizabeth back to the capital of Liones. As Elizabeth tries to resist, Meliodas regains consciousness and stops Veronica, trying to convince her that he will protect Elizabeth.

Angered further, Veronica triggers the Goddess Amber, the stone on her pendant that affects demonic beings. The stone shines brightly for a moment, and Meliodas then disappears. Annoyed at Elizabeth still refusing to return with her, Veronica finally orders Griamore to use force. Ban's attempts at opposing them are stopped by Jericho and Guila's arrival. While Veronica and Griamore are focused on Guila, Elizabeth manages to flee, with Veronica chasing behind; the princesses' footsteps trigger one of the explosive mines Guila had set previously, leading to Veronica's death. Guila then reveals Hendrickson's goal: the resurrection of the Demon Clan, and tries to bring Elizabeth back with her. As the princess pleads for Meliodas to rescue her, the Goddess Amber darkens, and shatters, releasing a black substance, which collects and forms Meliodas, the right portion of whose body is completely colored black from forehead to knee, with spiral-like designs. Noticing Guila holding his broken sword, Meliodas sewers, and grabs Guila's hand before she is able to notice; he holds her hand, which is, in turn, holding his sword.

As Guila screams in pain, Meliodas returns her amputated hand and lightly swings his sword to deliver a blow which knocks both Guila and Jericho away. Jericho immediately proceeds to utilize an Incantation Orb to heal Guila, when Meliodas continues to proceed attacking them. Losing conscious, he ends up slicing Ban in half as well as completely destroying the nearby terrain. He notices a worried Elizabeth and begins inspecting her through smell, causing her to gradually become confused. Acknowledging that she is not an enemy, Meliodas manipulates that black substance around his body to form a wing around his right arm, then heading off towards where King and Helbram was located. He interrupts the battle, knocking King away as he lands, and subsequently begins attacking Helbram. Preventing the Holy Knight commenting, Meliodas begins executing a succession of attacks, appearing to have gained the upper hand, when Helbram returns with a heavy blow. Helbram takes the opportunity and questions whether Meliodas was mixed from the start, as he appears to be fundamentally different from Guila and Jericho.

Appearing to be unable to comprehend what Helbram is asking, Meliodas continues the battle by manipulating the black substance again, but forming a gigantic blade instead, to send a series of slashes with aggressive killing intent. The Holy Knight deflects the strikes with ease, quickly moving behind Meliodas and attacking, thinking that his blow had accidentally split the Deadly Sin into two. Meliodas protects himself with the black substance acting as an armor and negating all the damage. He forms a wing again, attempting to reduce the distance between him and Helbram, when the latter uses the ability Hunter Wisp to create homing blast attacks, realizing that Meliodas has lost his Full Counter ability after they hit. Cornered, he molds two claws with the black substance and continues his attacks, only to be stopped Helbram who reveals his ability Link and stabs Meliodas with his sword.

Despite being told that Helbram possesses the powers of 20 more Holy Knights, Meliodas adjusts his posture and launches towards him, delivering consecutive bashes with the large claws. The 20 Holy Knights supporting Helbram via the ability Link are astonished that he has been overpowered, realizing that Meliodas' powers may still be increasing. Suddenly, Hendrickson appears before the gathering of the knights, lending Helbram a fraction of his powers, who consequently sends the rampaging Meliodas crashing into a wall with a single blow.

While knocked out, Meliodas was then saved by Diane with her sacred treasure Gideon and end up defeating Helbram, but as well destroyed Vaizel. When Meliodas woke up, Diane cuddles him in happiness. Later, Elizabeth ran happily to the saved Meliodas, but Meliodas was then punched by Ban due to being cut in half by Meliodas. Elizabeth then walks to the wounded Meliodas and hugged him for being alright, Meliodas was happy and told Elizabeth that she needs some underwear while grabbing her butt, leaving Elizabeth embarrassed and an upset Diane. Meliodas was then told by Ban of his sword fate which surprised Elizabeth and King of the missing sword, but Meliodas stated it was stolen and acting carefree which surprised Hawk. Elizabeth told Meliodas that sword was something important to him and said if it was really fine, to which Meliodas stated it is not fine, and it is a dire situation which surprised Elizabeth, but then Meliodas stated that if Elizabeth is alright, then losing the sword was not a big deal which made Elizabeth blush heavy and made Diane upset for not worrying over her instead to which Meliodas state that she is always fine.

Meliodas and the rest, treating each other wounds and headed to the next location to find another Deadly Sins member or the sacred treasure.

Armor Giant arc
As everyone was doing they own business, Meliodas was sitting next to a lake while resting from the Vaizel event. Meliodas realize that the Holy Knights are gaining so much power quick and should not hold back anymore. Meliodas then picks up a stick and swings it towards a mountain which was sliced in half, revealing that Meliodas was holding back. Meliodas then speaks of a prophecy that was mentioned by Dr. Dana and his daughter and said it was time to end the conflict foretold in it. Meliodas then mentions that he made a promise to Elizabeth and for the person who has fought by his side for so many years. Meliodas then mention that he will stop this three thousand years war.

While at the bar, Meliodas and the rest, meet a group of kids, who are led by Pelliot who are call themselves the Seven Deadly Sins. Meliodas told King that the information he got from him about the next member was fault to King embarrassment. Pelliot asks Meliodas why he put the bar in their location and demand them to pay them to which Meliodas told him that they were about to move. Diane, who was hiding behind, thought everyone came back, and appear to the kids who were shocked to see Diane, thinking she goes to eat them which got her angry, saying she does not eat people. After the misunderstanding was cleared up, Diane ends up playing with the kids. Pelliot then told them about a Mountain God who lives in Ordan mountain. The group was later informed by a villager that a group of Holy Knights and regular knights are doing a manhunt in the mountains for an evil criminal.

The Deadly Sins then hear from a barely surviving knight that an "Armor Giant" was at the mountain and beaten them all with ease. Meliodas then realize it was Gowther. Meliodas order Diane to stay behind to look after the sick Elizabeth to which the latter came out to hear the news. Elizabeth wishes to come along, but Meliodas told her she should rest since she is sick which made her blush heavy, remembering what he told her in Vaizel, but Meliodas thought she was having a high fever. Meliodas and the rest later head out to Ordan forest to find Gowther to which they were talking about how dangerous the Dawn Roar are and Ban telling Meliodas if he is okay fighting without his weapon to which the letter ask him if he was okay without a weapon. The Deadly Sins then stop to see Gowther as he was facing against the Dawn Roar. Meliodas and the rest notice that Gowther and the knights were not moving and realize that they were waiting for the first one to move to attack, but then the kids later came to the battlefield and Pelliot attack Gowther which made the latter smash Pelliot but Armando push him out of the way and get smash instead which trigger the battle.

As the Deadly Sins rush into the battlefield, was shock why would Gowther attack Armando to which Meliodas told King that they would worry about that later. Meliodas manager to stop Dawn Roar attack on Gowther, however Slader rush toward Meliodas and pin him down. Slader later left Meliodas and attack Gowther, Meliodas try to stop him, but Simon got in the way. As Weinheidt was about to shoot Gowther with a powerful arrow, it was stopped by the injury boy Armando who then reveal himself to be Gowther to the Deadly Sins shock. After Gowther made the Dawn Roar leave the battlefield by offering the Armor Giant head, Gowther reveal the Deadly Sins that the Armor has a beast in it which was once a Holy Knight. Gowther left the battlefield to make sure Pelliot is saved from the beast.

The beast was then about to smash Meliodas and Ban with it many fist finger but the latter dodge in time and sent out several attacks against the beast head, but the beast was not affected and sent them flying. King saved them with his Chastiefol Form 2 Guardian which he sent out to fight the beast but was defeated easily with it ice breath. Meliodas and Ban decided to use a random weapon they find on the ground and Meliodas charge toward the beast with a sword and a shield. The beast destroys the shield with it Despair Vemon, but Meliodas used a sword where he summons a black flame known as Enchantment since is the same flame he used on Ban to make his scar. When Meliodas was about to use a finishing move, he heard the beast voice and realize that it was still alive. Meliodas was then caught by the beast with its tongue but Gowther then came and saved Meliodas with a strange light arrow where Ban uses a wipe to grab Meliodas away from the beast.

Ban then scold Meliodas for not killing the beast, but Meliodas explain that the beast is still alive, but Ban told him to stop being naive. Gowther then use one of his power Invasion where he traps the beast into an illusion world where his heart most desire to see, Ban was about to kill the beast until Meliodas stop him, saying that the beast is partly human but Ban did not listen and remove the beast heart with his wipe. Meliodas grew upset with Ban for killing the beast, but Ban told him that they should put it out of his misery to which Meliodas respond to why not kill him. King then point out that the beast is mumbling something despite losing its heart and start releasing a lot of power. Meliodas realize that the beast they were fighting was actually Dale who was the father of Guila and a friend to them in the past.

Meliodas try to snap Dale out of his demon but Ban push him away when Dale tried to attack him and get slashed in half from Dale. King told Meliodas he will attack Dale with Fight Fire With Fire-Raining Daggers but has no effect on Dale and the latter spit out Venom Spit which effect King greatly. Ban got up and punch Meliodas and told him he should stop being naive and that he should fight back unless he wanted to lose his comrades. Meliodas then heard Elizabeth coming towards them and the latter toss a sword which is a sword that Meliodas got from his former lover Liz. Elizabeth told him that Liz does not want him to keep on fighting but to keep on living, and told him that she will share his sins whatever it is. Meliodas took Elizabeth word and catch Liz's Sword and cut Dale into many pieces with easy while apologize for slaying him.

Meliodas then apologize to everyone for being naive, but they forgive him. Meliodas and King wonder if Dale was cursed or been put a spell on him and wonder if this was the Holy Knights plan to the resurrection of the Demon Clan and Meliodas told everyone that the new enemy is not just Holy Knights. Meliodas went to thanks Elizabeth for giving him Liz's Sword and felt like something released from him. Meliodas then declares that it's now a death battle.

Meliodas introduces Elizabeth and Diane to Gowther and had a celebrating. When Meliodas offers Cain to have a drink with them before he departs. Rejecting the suggestion, he questions Meliodas whether he is projecting Liz onto Elizabeth, with the latter no replying. Meliodas went to chat with Gowther while talking how none of them are the same race and Meliodas proceeds to ask Gowther about what happened during the ambush ten years ago, to which he replies saying that it was Merlin who attacked and rendered him unconscious. Meliodas was shocked to find the traitor and ask Gowther if he knows where Merlin is to which the latter does not know.

Kingdom Infiltration arc
While traveling on the road, Meliodas group ask him of what the next Deadly Sins to find to which the latter that they are heading to Kingdom of Liones to get his Broken Sword back but the Deadly Sins refuse due to his fault of losing it. Meliodas got upset and went to Elizabeth under her skirt for comfort while she pats his head to Diane anger. Meliodas reveal to his group that the Dragon Handle is really one of the Coffin of Eternal Darkness and that the Goddess, Fairy, Giant, and Human Clan work together to seal off the Demon Clan in ancient past. Diane wonders why if the Demons are release yet, Meliodas reveal that there are more pieces to the Eternal Darkness since the seal is incredibly strong and there would have been a sign. Hawk ask why the Holy Knights are after Elizabeth as well, until a mysterious Holy Knight appears and reveal that Elizabeth is the last key needed to revive the Demon Clan.

As Meliodas try to reach Elizabeth, the mysterious Holy Knight just teleport herself along with Elizabeth to Meliodas anger. Meliodas took Liz's Sword and rush out and order Diane to toss him toward Liones since it is forty miles away. Ban grab hold of Meliodas as he wanted to head to the kingdom and Gowther appears along with them, revealing that he wanted to see Meliodas and Ban friendship. Diane grabs hold of the Deadly Sins as she told Meliodas to bring back Elizabeth, and toss them toward Liones at full speed. Meliodas, Ban, and Gowther just landed on Liones while running toward the kingdom. Holy Knights were aware of their arrival and sent out their Holy Knights to stop them. Meliodas told the Gowther and Ban that the mission is to save Elizabeth and to keep their fight to a minimum. Ban wonder if Meliodas minimum well is going all out which Meliodas respond that he will go all out as he charged at the attacking Holy Knights. As the Holy Knights used several abilities simultaneously, Meliodas got out Liz's Sword and used Full Counter which defeated and massacred a bunch of them with ease. Then a Holy Knight brute with heavy melee gauntlets ends up in their way trying to face them which Meliodas immediately knocked him out with a powerful punch and continued.

The Deadly Sins then stopped when they felt a large power coming from the south of the kingdom which turns out to be Camelot army with their leader Arthur. Later, the trio continued to cut through the Holy Knights as they attempted to break through. Deciding to end this with minimal bloodshed, Gowther used his Sacred Treasure Herritt to overwrite the memories of the attacking Holy Knights and turned them into allies. Gowther explained his technique to the bewildered Meliodas and Ban who then told him not to use that on them no matter what which Gowther complied. The trio sneaks away from the Holy Knights and went into hiding to find out a plan. Ban told Meliodas that they should head to the Liones castle because, in a fairy tale, the princess always get locked in an underground prison. Meliodas agreed to the plan and head out to the castle as Meliodas promise to save Elizabeth. The trio then senses a battle going on to the south gate which Meliodas decided to head over there, thinking Elizabeth could be there.

When Dreyfus announced the citizens of the Sins' presence, Meliodas keeps running while Ban called the Great Holy Knight a bastard. As Dreyfus was under Gowther's Nightmare Teller, a past version of Meliodas appeared having a meal after training with his fellow Sins. He comments on his superior's skills and called Zaratras invincible only for the younger version of Hendrickson to claim that Meliodas is being modest. He then compliments Dreyfus' sword skill and tells him that he lacks the skill and ambition to surpass his brother while munching on a handful of mini-Hawks. Meliodas disappears after telling Dreyfus that it is already too late and asked the skewered corpse of Zaratras if he is right, thus beginning the nightmare on the Great Holy Knight. Meliodas and Ban stopped at their track when they saw giant roots attacking a small town where Diane, Gowther, and King are located. Ban asks Meliodas if he could sense it, which Meliodas nodded as he mentions that Diane's and Gowther's powers are fading, but King's ability is raised to invincible level.

Meliodas later saved Arthur's life when Hendrickson used Hellblaze on the king of Camelot and Meliodas used Full Counter to reflect the attack back at Hendrickson much to his shock and Meliodas saying that Hendrickson learned a very dangerous ability while he was gone and told him that he is going to get Elizabeth back. As Meliodas stepped forward and faced Hendrickson, he asked him about the location of Elizabeth, but Hendrickson refused to tell him. Meliodas immediately tried to kick him in the face, but Hendrickson was able to block. Meliodas followed with quick slash attacks, but his opponent was able to dodge them with ease. Hendrickson then tried an attack, which Meliodas blocked, but was sent back. Moments later, Gilthunder came down from a thundercloud attacking Meliodas, who was able to parry his attack. Both exchanged multiple attacks, and both blocking each one of them, but eventually, Gilthunder was able to kick Meliodas in the chest and send him back, where he was caught by Arthur. Meliodas thanked him and asked him if he can give him a hand in the fight. He also asked him for his name, as Arthur told his to him, he also mentioned he had heard of him and knows him, and then they both prepared to face Gilthunder and Hendrickson together.

As Meliodas and Arthur were preparing for their battle against Gilthunder and Hendrickson, Hendrickson notices that the battle from the other side was over and believed that Dreyfus had won the battle, while Meliodas believed that none of his members would lose so easily either. Hendrickson points out that Meliodas came rushing into the enemy stronghold with a few members of his teams and without any plan. Hendrickson points out that the Deadly Sins were nothing, but a former shadow of themselves and that saving Elizabeth is futile. Meliodas however, rush in with great speed and attack both Hendrickson and Gilthunder at the same time and said that even if he gives up on his life, he will protect Elizabeth. Meliodas end up fighting against Gilthunder while Arthur was amazed at their skills despite not fighting seriously, but still end up fighting against Hendrickson.

As the Meliodas fight was proceeding, he was able to push Gilthunder back, but then he used an attack summoning lighting-beast-like attack from the thunderclouds. Meliodas used his Full Counter to reflect the attack but understood it that this was time delayed attack and had to reflect the other two incoming attacks as well. At that moment Gilthunder got behind him and slashed him, but Meliodas was able to block using the sheath of his sword, Gilthunder immediately went in front of him and with an attack was able to knock Meliodas' sword from his hand. Gilthunder then used a large lighting attack on Meliodas, but using the unknown dark power, Meliodas with just his fingers was able to stop Gilthunder's attack easily. Once Meliodas stop Gilthunder's attack, he regains his sword back and went on with the fight, without the Black Mark. Meliodas and Gilthunder battle rage on and shows that both of them are equality match. Gilthunder sent Meliodas flying to a building, but Meliodas stop the crash by putting his feet inside the building.

Meliodas ask Gilthunder if he really wants to have a death match with him, which Gilthunder respond by using Meliodas old creed of The Way Of The Knight which the creed goes "your eyes are to discern evil, your mouth to speak the truth, your heart is filled with righteousness, and your sword is to purge evil" but Gilthunder now believe that the Deadly Sins have turned down that creed and betrayed the kingdom. Gilthunder claims that he is stronger than any Deadly Sins, but Meliodas just nodded and continued their fight with full speed. Later on, Meliodas started to overpower Gilthunder, while the latter tries to fight back with all his strength, but with no luck. Meliodas try to slice Gilthunder, but Hendrickson appears and struck Meliodas which the latter dodge in time, Meliodas was surprised to see Hendrickson and saw Arthur was defeated. Arthur apologizes to Meliodas for not buying time, but Meliodas told him to rest and leave the rest to himself. Meliodas end up battling against Hendrickson and Gilthunder at the same time, while Hendrickson said that they need to take down Meliodas since he is their greatest threat. Meliodas started to nearly overpower the duo, until the unnamed Holy Knight who kidnapped Elizabeth, appear and freeze him solid with Freeze Coffin, but did not last long. Meliodas end up facing against Hendrickson, Gilthunder, and Vivian.

Meliodas begin to be overwhelmed by the Holy Knights trio, however, it was revealed by Hendrickson that Meliodas power is increasing instead of decreasing and the reason for Meliodas not fighting back against the trio is because Meliodas is heightening his utmost power and senses to unleash one decisive attack. The Holy Knights used all of their power together to finish off Meliodas before he could unleash his attack. Hendrickson summon Hellblaze, Gilthunder used Sword of the Thunder Emperor, and the Masked Holy Knight use Quad-Element Destroyer as Meliodas summon his attack, Divine Slayer. However, Margaret came running toward the battlefield to stop Gilthunder from hurting his hero, Meliodas. However, Meliodas spot something close to Margaret and use his Divine Slayer to kill an invisible creature like a demon that was next to her. As Meliodas grin of destroying the creature, the Masked Holy Knight attack hit Meliodas, heavily injuring him. Hendrickson rush to Meliodas to finish him off, Gilthunder appeared and cut off Hendrickson's arm. Gilthunder smiles and thanks Meliodas for setting him free from the spell as Meliodas smiles.

As Gilthunder cut off Hendrickson's arm, Hendrickson yelled out in anger for betraying him. However, Gilthunder pointed out that he was never on his side, to begin with. As Hendrickson try to summon Hellblaze with his left arm, Gilthunder stops Hendrickson and sent him flying. Gilthunder asks Meliodas to leave it to him as it was waiting for this moment for a long time to have his revenge against his father's murderer. Margaret stood there, lost at the current event and the monster that was close to her. As Meliodas clean himself and walk toward Margaret, the latter asks how Meliodas knew about the monster, Meliodas explain that he realize something was off when they met in Forest of White Dreams and realize what is wrong with Margaret a few moments ago. Meliodas explain that Gilthunder would never compromise his sense of justice if his life was in the line, and realize that Margaret was in danger the whole time. Margaret started to cry and thanks Meliodas for saving them. The Masked Holy Knight ask what made him realize the event, which Meliodas explain that the creed and the way Gilthunder said he was stronger than the Deadly Sins was some kind of code or charm if he was ever in trouble which Meliodas give him ten years ago, and when Gilthunder said those word back in the White Dream, he knew he was being watched and someone being taken, hostage.

The Masked Holy Knight finds it an absurd lie, as Meliodas was fighting against Gilthunder with all of his strength, but Meliodas points out that Gilthunder put his life on the line for the woman he loves, and as such, he put his life on the line too, as he believes that it is how friendships work. Gilthunder proceeds on defeating Hendrickson, and afterward he, Margaret and Meliodas meet up with the other Deadly Sins. Upon seeing Meliodas, Diane holds him and frets over him. Meliodas ignores Diane's fretting and tells everyone their priority is to save Elizabeth.

While the group heads to the castle to find Elizabeth and Bartra, Meliodas explains to them about Gilthunder and the Chimera that was following Margaret. Arthur shows up and compliments Meliodas' heroic deeds while the others are clueless on who is Arthur. Arthur confirms Gowther's suspicions of the mysterious power they felt earlier belonging to him at which Meliodas asks why he did not his powers. Arthur admits that he has no knowledge of his power, and wanted to fight a Great Holy Knight in order to awake his power. Meliodas and the others are dumbfounded at how Arthur decided to fight a Great Holy Knight without his powers. Meliodas and the others are suddenly teleported to a forest by Vivian, but fortunately, they are sent back to Liones by Arthur's mysterious cloaked friend. Meliodas quickly realizes that the cloaked figure must be Merlin of the Seven Deadly Sins, at which she reveals herself to the group.

Everyone was either shocked or happy to see Merlin. Meliodas, however, was displeased as he believes Merlin was the one who knocked him out ten years ago and wanted answers from her but decided to ask her later as they needed to save Elizabeth and Bartra to which Merlin happily agreed and teleported the group to the Royal Chamber. The group was shocked to be at the location so quickly and noticed that the Dawn Roar were there as well. As Meliodas was about to destroy the door, Merlin revealed that it would be impossible to break as it was protected by Perfect Cube, as it came from the Demon World and would not be destroyed with either strong or weak attack. Merlin used Absolute Cancel and break the spell, freeing Elizabeth and Bartra. Elizabeth quickly embraced Meliodas as she had missed him, to which the latter comforted her by touching her chest, which annoyed Bartra. Meliodas pointed out that they had defeated Hendrickson and freed the king, and asked Dreyfus what he would do next. As Dreyfus admitted defeat and cried after learning Griamore is alive, Meliodas happily declared that everything was fixed.

After the situation, Bartra started to cough blood which alarms everyone until Merlin came and offer to heal him back in Camelot along with Arthur. As Merlin was about to leave through the teleport, Arthur told her to wait as he went to Meliodas and offer him the title and rank of Great Holy Knight in Camelot as he believed that they were fated to meet. Everyone was surprised and shock at Arthur offer, but Meliodas accept Arthur offers to Elizabeth dismay as Meliodas believed that since the kingdom is saved, Elizabeth is freed, and Dawn Roar will take over the Deadly Sins job, they would be no need of him in Liones. Arthur was joyed to Meliodas acceptance, but Meliodas told him not yet as he needs to be in the kingdom to restore it, and he still has the Boar Hat to run. Meliodas then asks Merlin if she will rejoin the Deadly Sins who said not right away and teleport along with the sick Bartra and the depressed Arthur. King then ask Meliodas if he should have questioned her action in the past which Meliodas blame King for. Elizabeth came and ask Meliodas if he was really planning on leaving her someday, but before he could answer, the castle was cut in half, making everyone falls down. As everyone saved each other, they witness that the New Generation is turning into hybrid Demons, including Jericho and Guila.

As Jericho transform into Demon and was about to kill Jericho and the slowly transforming Guila, Gowther and Diane appeared and stop Jericho from killing. Gowther used Invasion on Jericho and Guila to keep them calm. King seeing the situation, was about to kill Jericho to save Diane as she has little strength left. However, Meliodas stop King for a moment and told him it was strange how all the New Generation suddenly became Demons, and realize someone has active them. Hendrickson came face to face with the Deadly Sins and the Holy Knights, explaining that he did all of this and was after Elizabeth. Hendrickson offers to spare Meliodas and the others if Elizabeth comes with him, as he does not want to kill "one of his kind", but the group refuses to hand over Elizabeth to him, and King ambush him until he was attacked by Helbram who was revive thanks to Hendrickson forbidden technique. Hendrickson explains to King how he found Helbram and that now he is just a lifeless shell of his former self which brought the Fairy King to tears, knowing that his friend is a slave to Hendrickson. Meliodas and Gilthunder were furious at Hendrickson cruel nature and attacked him until they realize that Vivian took Margaret and Elizabeth hostage. Hendrickson then stabs both Meliodas and Gilthunder to the three girls shock as Vivian thought that she was going to be with Gilthunder forever, never leaving her. However, Hendrickson explains that Gilthunder will never leave her as a revived corpse to her shock. Elizabeth decided to go along with Hendrickson to save Meliodas life to everyone shock. Hendrickson accepts her offer and was only planning to spare Meliodas, but he will spare Gilthunder as a bonus.

As Hendrickson summon a black matter wing, Elizabeth told Meliodas to think about their promise and was taken by Hendrickson to an unknown location to Meliodas dismay. Gilthunder was being heavy affected by Hendrickson ability, Acid which Meliodas said that they could either defeat Hendrickson now or dispel the spell before Gilthunder body rot. When Ban and Hawk appeared to them, Meliodas and Hawk agreed to go rescue Elizabeth and ask Ban for help. However, Ban started to attack Meliodas to the latter shock as Ban rip Meliodas arm off. During the battle, Meliodas fought Ban, but was not at his full power due to the Acid effect and used Demon power to reattach his arm. As Ban witness Meliodas ability, Ban ask Meliodas that if he is a part of the Demon Clan to which Meliodas did not respond as Ban took it as a yes. As they battle, Meliodas was put against the wall and Ban revealed that the Goddess Clan promise him to revive Elaine if he killed Meliodas. Meliodas understood Ban, as he always hears him sleep talk about Elaine, and decided to accept death for Ban.

Ban was surprised at this sudden event but decided to do as Meliodas wish, saying he will never forget about Meliodas and told Elaine to wait a bit longer. As he was about to kill Meliodas, the latter jump up and head-butt him in the face which made him bleed. Ban grow furious at Meliodas action, saying why would he accept Ban offer, but attack him. Meliodas told Ban that he did say he is okay with Ban killing him, but did not say he would not fight back. Meliodas then told Ban that Elizabeth thinks nothing of sacrificing herself and for their promise to save Liones, knowing that, he can not die right. Meliodas told Ban that despite what he is doing, Ban will be his friend, no matter what, but like him, he got things that he can not give up on. Hawk then count front Ban, saying if he will really what the horn would say and that is not Meliodas his friend. Ban told Hawk that Meliodas was his greatest friend, but want Elaine to be back. Upset at this, Hawk said what if Elaine did not come back, he will lose his friend and Elaine might not be happy about this. Ban told Hawk what should he do, as when Elaine died, he was depressed, but when he met the other Deadly Sins, he kept himself distracted, but he still knows that he will be alone forever, be it in this world or next, saying this world without her is like Hell. Hawk did not understand Ban, but Meliodas said he understood Ban but said that they should put their fight in a hold until they solve the current matter as the Deadly Sins, which Ban said he understands.

Meliodas than ordered Hawk to carry him to Elizabeth location where it is in Merlin old castle while he sleeps on Hawk to regain his strength. Hawk agreed and gladly took Meliodas to save Elizabeth and because he is his friend. Hawk and Meliodas later arrive at Merlin's Old Castle where Meliodas was shocked to spot the bleeding Elizabeth and the deceased Dreyfus while Hendrickson knew that Acid would not work on Meliodas because of their "detestable power". Hendrickson went on to say that he was a Druid, who are sorcerers in a deep forest. Druids are also known to revere Goddesses and nature and shun the abominable Demons. Hendrickson explains that when he first met Meliodas, he felt malevolent, massive powers coming within Meliodas which was a greater power than Zaratras himself and could not get a single read on his thought which made Hendrickson feared, interest and admired Meliodas. However, Hendrickson admits that he now possessed the same power as Meliodas, until Meliodas quickly went pass him and carried Elizabeth without him noticing as he did it again to give Elizabeth to Hawk, so he could take her somewhere safe as he told her that both of them will run the bar again if she survives to comfort her.

As Hawk was running away with the princess, Hendrickson was about to use Hellblaze on them, until Meliodas appeared and slice off his arm once more. As Meliodas overpower Hendrickson, the latter somehow got control of his severed arm and still use Hellblaze on the runaway until Diane appeared to save them and crush his severed arm. Hendrickson was shocked to see Diane well and not in near death like before until King Guardian appeared behind him and smash him. Hendrickson rises up to see the five members of the Deadly Sins (Meliodas, Ban, Diane, King, and Gowther) appeared and challenge him to a final battle. As Hendrickson taunt the Deadly Sins for being outnumbered due to the New Generation transforming into Demons, Meliodas pointed out that he should check again. Hendrickson senses that all the New Generations were stopped as they return to normal due to Ban and King help while the other Holy Knight's are currently surrounding the ruined castle. Hendrickson, however, was joyful to admit that the situation became more interesting and wonder how the Deadly Sins defeat the New Generation so fast but admit that the Sins can not defeat him.

As the battle went with the Deadly Sins working together to fight against Hendrickson, the latter admits that he is invisible due to the demonic power, but when Diane trap him with Double Hammer, Meliodas explain to Hendrickson that demonic powers can heal wound, but if he is not immortal or something, it would have been pointless as he would not completely handle it for a while. Hendrickson than smash Ban into the wall where the latter found the demon corpse and return to Hendrickson, smashing against the wall furious for having the demon while questioning him for having it. The wall breaks down to reveal the demon which shocks the Deadly Sins. The Deadly Sins were shocked to see the Red Demon corpse as Hendrickson explain that he found it in the Fairy King Forest long ago and what a great blessing it was to him. Hendrickson used the power of the Red Demon and summon wipe that nearly stabs the Deadly Sins despite for Ban who used this to get closer to Hendrickson and slam him to the ground while furious, telling him that he can not beat him since he was the one who killed the Red Demon.

When Hendrickson was sent underground, Ban destroys the Red Demon in anger while they follow Hendrickson underground as they can still sense him and something greater. Leaving Diane behind due to her size as she is unable to fit in the hole, the Deadly Sins traveled inside to discover Hendrickson who revealed that he has another Demon underground that he discovered years ago, which was a large sunflower head Demon knows as Gray Demon which is much higher than the Red Demon. Hendrickson took a blood sample from the Gray Demon's corpse and injected on himself, resulting to gain tremendous power-boost from the demon. Ban still attacked Hendrickson despite the warming Meliodas give to him, ending up half of his body blow up with ease. Meliodas along with the other Deadly Sins, was blown out of Merlin Old Castle and badly injuries due to Hendrickson newfound power. Meliodas try to stop Hendrickson from getting Elizabeth by stabbing him, but the blade barely went in and was tossed aside with ease. During Hendrickson assault on the Holy Knights and Deadly Sins, Meliodas protected Elizabeth from all of those attacks but collapsed when he was no longer able to handle it. Meliodas pleads Elizabeth to escape, the latter refuses, leading Hendrickson to unleash Dead End. When all hopes are seemingly lost, Hawk suddenly appears to save the paralyzed Meliodas.

Meliodas plead Hawk to escape, but Hawk took the attack, killing him in the process. Meliodas grows furious at his friend death, but not as much as Elizabeth which unlocks her hidden powers and revealed her right eye with a strange symbol. When Elizabeth healed everyone, Meliodas was unsure about Hawk as he knows that Elizabeth ability can not heal those who have been kill which brought Elizabeth to tears. When Hendrickson was about to kill Gilthunder, Meliodas charge toward Hendrickson, kick him in the face and punch him in the stomach which made Hendrickson collapsed on the floor while Meliodas told everyone to not lose hope while in his Black Mark mode once more. As everyone seems to lose hope as they continued their assault on Hendrickson did not work, Meliodas ordered Gowther to use Broadcast to everyone to explain his plan which everyone was shocked, but went along with it. Meliodas end up fighting Hendrickson head-on while the Holy Knights launch their attacks on Meliodas and Hendrickson displease Hendrickson remain unaffected while Meliodas is taking damage. During the battle, Hendrickson realizes Meliodas can not use Full Counter because his power was not healed, only his physical strength.

Despite Hendrickson trying to put Meliodas down, saying it is only futile to continue to fight him as Meliodas can not use Full Counter and was about to use Dark Nebula on Meliodas, but Meliodas continued to push on as the latter step inside Dark Nebula and punch Hendrickson, destroying the attack. Everyone continued to assault Meliodas with all of their powers at the same time while Elizabeth plea everyone to stop despite it was Meliodas plan, to begin with. After Ban attack Meliodas, Hendrickson felt an incredibly high power level coming within Meliodas which shock even Hendrickson. Gowther revealed that this was Meliodas ultimate attack as he doubles everyone power attack that he took and was about to unleash it on Hendrickson. Gowther also revealed that surviving this technique is 0.2% which shocks and scared Hendrickson into flying away, but was trapped in Wall by Griamore and Meliodas jump up toward Hendrickson while the latter asks why Meliodas is doing this for the people who framed and attack him, but Meliodas response that Hendrickson committed a sin for abandoning his friends to protect for powers and unleash Revenge Counter, killing and destroying Hendrickson body.

Meliodas later fell back down from his battle against Hendrickson as Elizabeth came rushing to his side. As the two got closer, Bartra coughs and told them to be kept separated as he returns from Camelot after being healed by Merlin. Meliodas and Elizabeth greeted the two from their return and after Bartra forgives the Holy Knights for their crime and cleared the Deadly Sins name, Elizabeth, however, was still depressed as Hawk was still dead from protecting Meliodas. While Ban grieves over Hawk dead body, Meliodas came closer to Hawk dead body, telling him if he makes it alive, he will give him the triple amount of leftovers he can eat. For an unknown reason, the black matter on Hawk body started to fade, revealing that Hawk has been revived, but shrunken to smaller size, but this still greatly bring joy to the Deadly Sins, especially Ban. Elizabeth then puts Meliodas' face into her chest which is something she never did before but ended up healing Meliodas with her rune eye while still tearing for joy as Meliodas and Hawk are still alive. Meliodas than embrace the princess, ending their adventure in Liones.

Post-Kingdom Infiltration arc
As Liones was being rebuilt due to the battle, Meliodas and Hawk watch over the injured and unconscious Elizabeth as she rested in her bedroom. Hawk wonders why Elizabeth did not heal herself while she healed everyone else in the kingdom. Merlin appears out of nowhere after teleportation, and states that Elizabeth unlocked her power without giving much thought. This healed everyone else because she was thinking about others over herself. Even if Elizabeth had some magic left, she would not heal herself which led to Hawk tearing up, believing that Elizabeth should have thought of her own health first. Meliodas and Merlin discuss the issue regarding the location of the Coffin of Eternal Darkness as it was no longer in Liones. When Merlin used her "Location" spell, it was revealed that a strange bird appeared and fled to the east. She then reveals that she told Arthur that she would be away for a while as she will rejoin the Deadly Sins for the time being.

This made Meliodas glad as she could help them, but he still felt uneasy by her suspicious smile. He states that he still wanted to know what happened ten years ago while Merlin seemed to be interested in Hawk, calling him a hero which made the tiny pig happy and befriend her. Meliodas realizes that he forgot something and went back to Elizabeth's room. Hawk yelled at him, stating that he should not do anything weird to Elizabeth while she is asleep. When Merlin and Margaret appeared in front of Elizabeth's room, Meliodas stepped out of the room with a grin. Some were worried that he did something weird until it was revealed that Elizabeth was up and healed for an unknown reason. Hawk was overjoyed to see Elizabeth being able to walk about but wondered why it was possible. Merlin seemed to know what Meliodas did as it was revealed that he held Elizabeth's hand and told her that he could not possibly live without her which made her wake up.

Meliodas takes Hawk back to the Boar Hat as Ban feeds Hawk with expired food. Gilthunder appears in casual wear, wanting to have a talk Meliodas. The two sit down and enjoy some Bernia ale, being commented by Gilthunder as having a good taste, despite the fact that he called it "only slightly better than a horse's urine" before. Gilthunder states that he is going to relinquish his position as a Holy Knight and become a wanderer. It was to clear his mind from his sin he committed as a Holy Knight despite him working undercover and trying to protect Margaret. Meliodas decided to not place pressure on Gilthunder to give up on his plans because he was already a man and that his decision should be respected. However, he wonders how would Margaret take it. Ban decides to tell Meliodas that he is not just leaving the Boar Hat, but withdrawing from the Seven Deadly Sins, much to Meliodas' surprise. The next day, Meliodas acquires a brand-new uniform from Elizabeth which he plans on wearing from now on. The rest of the Sins get new uniforms as well, except for Merlin. The Sins end up celebrating the festival while working in the Boar Hat.

The next day, when Bartra was about to award the Sins and Hawk for their efforts in restoring the freedom of Liones, Meliodas notices that Hawk has regrown back to normal size and that many Holy Knights were whispering behind Meliodas' back. When Bartra was about to give the award, Meliodas yells an objection to everyone's surprise. When Bartra questions him the reasons behind his objection, he explains that he could not possibly accept the award while everyone was whispering behind their backs and demand to know who they were. A group of Holy Knights, Dogedo, Waillo, and Deathpierce, the Pleiades of the Azure Sky who served under the Great Holy Knight, Denzel, came to Liones to question the Sins regarding the defeat Hendrickson, claiming that they were not strong enough to beat him and demanding to see how strong Meliodas truly is.

Bartra allows the fight to go on as Meliodas fights against Dogedo who is proven to be a powerful Holy Knight, but Meliodas easily dodges his attacks and strikes him. Dogedo insults the Holy Knights and the Great Holy Knights for being weak as he believed that being a true Holy Knight is to wield great power, but Meliodas disagrees and believes that it was the heart that makes a Holy Knight and easily defeated Dogedo by breaking his fingers and landing a punch on him. As Meliodas challenges the other members of Azure Sky, Deathpierce rejects his challenge as the Holy Knights realize how strong Meliodas was. They end up apologizing for their rude behavior. Dogedo was upset as his friend has died during the battle against Hendrickson. Meliodas and the others go to Bartra's throne room where Bartra thanks them for their services but have a grim expression. He states that the Holy War would still be approaching, but has a new view into the future as he saw three heroes fighting against a mountain giant in Camelot. As the group discusses Bartra's warning, they sense a large earthquake that was coming from the east. Meliodas knows the origin of the power and was in a state of shock and anger.

The next day, Elizabeth runs towards the Boar Hat, wearing a new waitress outfit. She asks Meliodas if she could work in the Boar Hat since the Sins were going to Camelot on a mission by Bartra's orders. However, Meliodas refuses to take her in as her father would be mad for letting her work as a waitress, but she told him that she does not care and wants to run the bar together with Meliodas as they promised. He states that he did not make a promise to her and since they saved the kingdom, there was no need for Elizabeth to work. When she questions Meliodas for being aloof towards her, he starts to harass her the usual way to prove that he is not being aloof until Hawk comes and ties Meliodas up. When Meliodas went to Merlin's house, he comes across Gowther, telling him to get ready for the mission in Camelot. The Sin of Lust refuses to Meliodas' surprise and goes on his date with Guila. Meliodas does not understand as he has never seen the two of them together.

Albion arc
As Meliodas gives several thoughts about it, Elizabeth and Diane exit Merlin's house. Elizabeth spots Meliodas and runs away in embarrassment while Diane decided to follow her. When everyone exits Merlin's home, Meliodas enters, demanding to know what happened ten years ago and wants something that was stolen from him. Merlin reveals that she knows that the Demon Clan was set free and believes Hendrickson is still alive. Meliodas was not stirred by the belief that Hendrickson was still alive. What worried him the most were the ones who were set free as he believes that they were the Ten Commandments who were handpicked by the Demon King himself. Merlin gets a bit exhausted as the items in her room fly around. She then asks to talk about this real issue. Suddenly, Merlin and Meliodas were struck by Gowther's Blackout technique that knocked out everyone in the capital unconscious except for Diane and was believed to be affected as well. But later on, they're revealed to be alright as they searched around the city to find the cause of the anomaly.

There they find Elizabeth regaining consciousness and then the aftermath of the skirmish between Diane and Gowther appearing to be ended in a draw. After the short scuffle has been settled for now with Gowther returning Guila's old memories as well as Zeal's including the breakup of their relationship, Meliodas and the others returned to the bar where Slader agree to join with them for a while and Elizabeth wanted to join, but Meliodas shut her down coldly to avoid her getting hurt by the Ten Commandant to the displease of others. However, Merlin got a call from Arthur who was under attack from an Albion and teleported to Camelot to battle the giant.

As the knights of Camelot battle the demons' giant golem, Albion, Meliodas and others aid them while fighting the beast. While Meliodas led Arthur and his men on the giant arm, Meliodas sword, Liz's Sword was destroyed during the battle. While Merlin still refuses to return what she stole from him, she was willing to return his Sacred Treasure, Lostvayne which he uses to split himself into several copies and easily destroy the golem with Full Counter. While some part of the kingdom was destroyed, Arthur thanked Meliodas and the others for their help while Elizabeth felt sorry for Meliodas having his sword broken as it was a great treasure to him, but Meliodas revealed he was fine with it and felt that both Liz and Elizabeth have been looking out for him for a long time. While the group chats fondly, Galand of the Ten Commandments appeared and challenged everyone for a fight. Meliodas was shocked to see him as Galand revealed that he knew Meliodas and was surprised he had not aged for the last three thousand years, but still attacks him. While the Deadly Sins fought bravely and Meliodas even used his demonic power, they still lose to Galand and were believed to be killed by Galand which was revealed to be Invasion by Gowther.

Istar arc
Meliodas later had a nightmare where he loses Liz again and woke up facing Elizabeth who was in tears for worrying about him. Elizabeth soon took Meliodas where the others are healing and sad about losing to Galand. However, Meliodas soon lift everyone spirits by stating they have to train more to get stronger, and as a strategy, Arthur and Elizabeth would have to awake their hidden powers as well. Meliodas believes the situation was so bad, they have to bring in Escanor. Later he checks up on Diane's health with King. It is revealed then that she seems to have lost all of her memories up to the point of meeting Meliodas the first time.

While Meliodas and the others talk about Diane's lost memories, King kept Diane company until she started to lose more memories and ran off. Gowther soon revealed that he used Lost World on her to test if her feelings for King were stronger than she said, provoking King to punch Gowther. The others follow Diane who was heading to Megadozer until they are stopped by Monspeet fire ball which Hawk Mama eats, to the others surprise. While they could not sense Diane power level anymore, Meliodas believes she is fine and should focus on their training until they meet Diane again. Meliodas decides the first thing to do is head to Istar, the home of the Druids and the location of Meliodas strength.

While the Boar Hat traveled to Istar, Merlin revealed the reason for her to steal Meliodas power was that he could not control his emotions very well, and nearly destroyed Liones when a young girl got herself injured during the framing ten years ago, possibly being Elizabeth. Merlin then somehow steal Meliodas strength and give it to the Druids for safe keeping. Once they travel there, they were greeted by the head of the Druids, Jenna and Zaneri along with their bodyguard Theo. When they request them for training and Meliodas strength, they agree to help out while Zaneri led Meliodas and Elizabeth inside the castle to test them. Zaneri soon revealed to have feelings for Meliodas as she wants him to grope her and seem jealous of Elizabeth, while Meliodas show no interest in her. Zaneri then tests Meliodas by sending him through memory lane to the day Danafor was destroyed to see if he could control his emotion when Liz died. However, Meliodas repeatedly the day so many times, he soon started to lose it until he was inspired by Elizabeth and tried it once more, passing the test to Zaneri surprise.

Meliodas soon went to the training ground where the others were training and pair off with King. However, once inside, King started to fight him instead of the Amber they were supposed to choose. King started to question Meliodas motivation and that if he was on their side which Meliodas refuse to answer as he believes King would not believe him anyway. After much battling, the two come to an agreement to work together while King keeps an eye on him. Once out of the training cave, Jenna gives back Meliodas strength which could be sensed by the Ten Commandments from afar. Meliodas soon request Merlin to teleport him to the Ten Commandments location to greet them and payback at Galand which she did, but only for ten seconds. Meliodas used the ten second to utterly defeat Galand and said his greeting to Zeldris which the latter and Fraudrin attempt to attack him, only for him to be teleported away before they connect.

After returning and revealing everyone that he made the Commandments to spread around the land, they soon scolded Meliodas for making them angry and cause havoc. However, Meliodas soon revealed that he made them split up to be easier to take them out then fighting them in a whole group which calm the group down, but King remain unease with Meliodas decision. Meliodas check out the other's group training which led to Arthur having a cat-like on his head and Griamore to be a child again. Meliodas then see Hawk new form which he was stunned, but ignored him and soon ask Zaneri how Elizabeth doing in her trials. Elizabeth returned to the group to see how their training was. Elizabeth also got a new outfit for battle as Zaneri believed it would be easier for her to move while Meliodas enjoy the outfit and led to him poking Howzer eye for ogling Elizabeth, hinting a jealous side. Meliodas ask Elizabeth how was her training. Elizabeth responded that she failed respectful to everyone surprise. After everyone's training, the Deadly Sins decided to head out to stop the Ten Commandments and find Escanor. Before heading out, Meliodas cheered Elizabeth up for failing her trial by saying it's okay to fail as he failed the trials a thousand times and knows that Elizabeth has some crazy power hidden. This quickly cheers Elizabeth up and promise to be of help to them and soon restore their relationship.

While traveling, Meliodas asked how Gilthunder and Howzer training was and noticed they got stronger to Gilthunder joy. Meliodas soon got around to ask Hawk what happened to him while training which Hawk revealed that he got eaten by a Tyrant Dragon while being paired up with Oslo, but Hawk soon ate his way through the dragon stomach and somehow gain its abilities, even though they are a weaker version of them. Hawk soon read Meliodas and was a shock to find out that Meliodas power level increase to 32,500 and was stunned to find out that Escanor is far stronger than Meliodas, but Meliodas soon revealed that despite getting his power back, he needed to train along the way to get stronger as he became rusty.

Ravens arc
After the activation of Melascula's magic, Meliodas and King discussed the latter's temporary departure from the sins, to which the former asks if it were to look for Diane. Before King's departure, he questions how all the people there can be so loyal to Meliodas when he is clearly untrustworthy, yet Meliodas remains calm and says nothing. Elizabeth attempts to persuade King to no avail, he leaves and Meliodas tells him if something happens, to give them a call. The sudden disappearance of Ban's power causes Meliodas' to knock over a bottle of beer, whilst he was cleaning the bar. He mutters Ban's name, unaware of the events taking place miles away.

Great Fight Festival arc
Meliodas knocked down a bunch of Earth Crawlers while meeting back with Arthur. When he cooked their meat, it tasted horrible and decide to save the scraps for Hawk. Later, Meliodas and Arthur meet with Ban, immediately have an arm-wrestling match with Ban wins easily. Meliodas forgives Ban who still relatively depressed about having tried to kill him back at Liones and invites him to come along to search for Elizabeth and the others. After the duo makes amends with one another, Meliodas is able to sense that Elizabeth is on the other side of a large wall, with the two both nothing that he would reach her soon. Ban and Meliodas both release respectively powerful attacks, resulting in the structure between himself and Elizabeth's group being destroyed, but an entire open path to the other contestants and the hosts themselves. After Gloxinia fatally wounds Escanor and quickly brings him back to optimal health, he has Drole split the group into teams of two.

Ban and Meliodas find themselves working together, though they wait in great suspense as both Elizabeth and Elaine begin their match. Once it's over, the two themselves have a cakewalk defeating a pair of blue demons, all the while debating over who's girlfriend was better and not even noticing the fight was really started. Once King and Diane's matches are over, it's now fallen upon Escanor and Hawk to fight Jericho and Gowther. The latter's attempt to control Lion's Sin fails, as he ends up using Merlin as his own 'sun' and Rhitta's stored Sunshine power to attack Drole and Gloxinia. Taking advantage of this, Meliodas quickly rushes to attack the injured commandments. After injuring Drole quite grievously, the demon resorts to taking hostages out of his comrades, though this is ineffective as the Sin of Wrath removes the remaining two arms he has left in response. Controlling the tide of the battle for the majority, slicing through Drole's body and arms as well as manhandling Gloxinia, the former Fairy King's armor even breaking after landing a blow on Meliodas. It was likely the battle would have ended in his favor, up until the rest of the Ten Commandments had arrived on the scene.

Once on the scene, he was a quick stare off against Zeldris, before attacking his younger brother with LostVayne, only to have his own arm caught off mid-swing. In retaliation, the Dragon's sin kicks the commandment away in order to retrieve his detached arm only to be stopped by his brother once again. After being put under a chain jail spell by Grayroad, he retrieves and attaches his arm once more after a brief exchange with Zeldris, smashing the ground to create a smoke screen and escape, only to be barred from doing so by said jail spell. After being attacked by Derriere's Combo Star attack, his wrists are battered harshly, only to be praised for surviving and soon after attacked by Monspeet. Emerging from the flames and slicing through the former's throat to no avail, he finds himself without his mark and hopelessly outgunned. After pleading for Dreyfus to fight Fraudrin's control, the demon feigns as such only to attack Meliodas with Break. Gloxinia being equally brutal in attacking with Vasquez, resulting in a large, powerful explosion that leaves the captain looking exhausted and once again with his arm blown off. Appearing to be defeated and scolded by Zeldris, Meliodas activates Revenge Counter, having gathered enough strength to frighten 8 of 9 remaining commandments with the possibility of either death and or defeat. However, this is quickly dispelled thanks to Estarossa's Commandment, and Meliodas is left powerless.

Estarossa then goes on to antagonize his brother for how he betrayed them, wishing to hear him suffer more whilst he continued stepping on him, Meliodas mouthing something though he seems to be unable to completely speak it. Then going in depth about how in the past, when Meliodas was the leader of the original Ten Commandments, he admired his strength and heartlessness, and that he could have become the Demon King. Melascula then steps up, desiring to eat Meliodas' soul for herself, wanting payback for what transpired with Escanor and Ban. The immortal himself shows up soon after this, snapping the demon's neck, removing her hearts, and destroying them effectively killing her. Despite his intentions, Meliodas, though with a smile, reprimanded Ban for jumping in so recklessly, with Ban remarking that idiots stick together.

After being assisted to his feet, Ban is soon after thanked for killing Melascula citing that he'd have done so himself if he had not for trying to take his brother's very soul. Though the distance between them is cleared quickly, having stabbed Meliodas in one of his hearts before either sin could react. Using an attack he calls Rebellion to summon six other swords, Estarossa explains that the upper echelons of the Demon Clan have seven hearts, and once all of a demons hearts are crushed, they die. Ban attempts to stop Estarossa, but he is ignored as Estarossa stabs one heart after another, finally killing Meliodas.

Defensive Battle for Liones arc
One month after Meliodas' death, instead of moving on the Capital of the Dead, Meliodas is lingering in Purgatory. There he discusses his fate and his past self with the Demon King. The Demon King states that he will feed on Meliodas' emotions to regain his lost power and to return Meliodas back to his former personality. Meliodas refuses and attacks. When Meliodas finally returns to the living world, he finds that the Ten Commandments have been wrecking even more havoc. He saves Elizabeth just as Derieri was about to kill her, punching a large hole in her abdomen. He then apologizes to a crying Elizabeth for taking so long to come back.

Derieri interrupts them striking Hawk Mama, after chaining several Combo Star attacks. Hawk tries to intervene but is kicked by Derieri. This provokes Meliodas, who grabs Derieri by the neck and smash her into the ground, resetting her combos in the process. Meliodas starts to get relentlessly attacked by Derieri, however, Meliodas effortlessly deflects all hits. He knocks her down, resetting the combo again. Derieri continues attacking Meliodas in vain. Meliodas states a quote that describes how his old self would have approached the current situation. Monspeet intervenes in the fight to aid his partner, shooting his technique Kaijinryu at Meliodas, but before the attack reaches him, he kicks Derieri into the air and uses Full Counter, after activating his demon mark. The attack is reflected towards Monspeet and Derieri as well, seemingly destroying them.

After that, Meliodas joins the fight against Fraudrin. Fraudrin battles Meliodas, but even with his gigantification ability, the Sin overpowers him with ease. Merlin realizes that he is using a clone, stating also that his power level is now 60,000, and after activating his demon mark is even higher. Fraudrin exclaims surprised how Meliodas' power is similar to how was in the past. He tries to attack, but Meliodas swiftly attacks Fraudrin, piercing multiple holes in his body. Severely injured, Fraudrin shrinks to his normal size. He says that he and the other Commandments have been waiting to take revenge against Meliodas and the goddesses. Meliodas compressively pats Fraudrin's face, but then rudely pushes him to the side. Ban feels that there is something off about the captain. Meliodas remarks how Fraudrin is not an actual Commandment but rather a substitute. Fraudrin talks back saying that Meliodas cast aside the pride of the Demon Clan. Fraudrin then decides to wipe out Liones by immolating himself. Meliodas gets bored and tells him that he should just hurry up and die. Griamore stops Fraudrin from self-destruction. Fraudrin, moved, surrenders and tells Meliodas to kill him. Meliodas mercilessly kills him without a moment's thought.

Ban walks towards his captain, telling him that he's glad his partner is not dead and decides to have a toast later. Later Meliodas searches through the destroyed Boar Hat for food and beverages. Elizabeth found Meliodas and eats with him. She states how Meliodas is a generous and gentle person. Meliodas tells Elizabeth how Ban was looking at him with an unrecognizable look. Then Meliodas starts to describe the giddy feeling he had when he killed Fraudrin. He starts to cry and admits that he is scared of turning into the way he used to be. He continues to say that he will not be able to save Elizabeth if he does not turn back to his old self. Elizabeth comforts Meliodas and declares that she will never leave his side no matter what.

Meliodas visits Merlin and Escanor while she is taking a bath. Ban asks where Meliodas was because they could not celebrate properly and then apologizes for not knowing what expression to make. Meliodas tells him that there was nothing to apologize for. Ban insults Meliodas' vacant look, and he is punched by Meliodas so that he would shut up.

Memories of the Holy War arc

 * See 3000 years ago section.

Corand arc
When King and Diane fell out of the sky, Diane landed on Meliodas, and after stating that they wish that the captain was still alive, Meliodas tells them that he still is alive. Diane and King are shocked, believing that he is a ghost, however, Escanor tells them that is the actual captain. Meliodas skips through a long story and said that he was revived, and then King replies, telling him that was too short. King apologizes to Meliodas, and then Ban and Meliodas check out King's wings. Meliodas congratulates him on growing wings and is then teased by Ban. Meliodas notices that there is something different about King and Diane. After Diane talks about the promise she made 3,000 years ago, Meliodas and Merlin become shocked. Meliodas questions if she actually said 3,000 years ago. After Bartra shows Gowther's "heart", he then runs away, and Meliodas and the other sins help Diane and King catch him by law number 4 of the Seven Deadly Sins.

Ban asks if Meliodas knew that Gowther was a doll, and Meliodas responds, saying that he also knew the person who made him and describes him as a powerful magician that the Demon King acknowledged. He continues to describe the commandment, Selflessness and why the Demon King imprisoned him. Adding on, he said that Gowther (the doll) was a substitute, modeled after his lover with a male body so that he would not feel any lust towards the doll. Since Gowther is a doll, it made it hard for them to locate Gowther. After Gowther gets his heart back, Meliodas states that they did not have to intervene.

Awaiting the unveiling of the newly rebuilt Boar Hat, Meliodas and Ban impatiently wait for Hawk to reveal it. Because they could not wait any longer, they both took off the sheet on the building. They raced to get the room that they desired, and since they could not decide who would get the room, they flipped a coin.

To celebrate Boar Hat being rebuilt and the reunion of the Seven Deadly Sins, Meliodas, and the sins had a drinking party. Meliodas drank a barrel of alcohol while Diane cheers him on. When Merlin arrives, Meliodas notices something wrong with Merlin. With all the sins in the room, they toast to the reunion. Diane asks Gowther how his creator ended the Holy War, and Meliodas and Merlin questioned that. However, Gowther could not give a response. Meanwhile, Elizabeth keeps thinking about how there was an Elizabeth with Meliodas 3,000 years ago and questions it. Meliodas comes out of nowhere and harasses Elizabeth, asking her why she was staring off. He lets Elizabeth knows that she can ask him anything, which leads to Elizabeth telling him that she wants to talk later. After Elizabeth walks off, Merlin reestablishes the fact that Zeldris is still alive. Meliodas prioritizes freeing the people of Liones and liberating Camelot first before fighting Zeldris. When Merlin walks off and enters a room, she almost collapses and is caught by the captain. Meliodas then asks if Zeldris did something to her, however, she tries to avoid answering it. He sets her on the bed and tells her that he knows she's trying to protect Arthur. Gasping and begging Meliodas, she asks him to help because he is her hope.

A while after Merlin passes out, Meliodas and Elizabeth walk to a mountain for their talk. He asks Elizabeth if she recalls playing on the mountain with him when she was a kid, however, she does not really remember that time. She asks him if he thinks it's a coincidence that Liz passed away 16 years ago, and she was born 16 years ago and that they had the same name. Meliodas remarks how they were not alike. She continues to say that during King and Diane's training, they met another Elizabeth that looks just like her. Meliodas becomes surprised that they know that and starts getting worried. Elizabeth sort of freaks out, but Meliodas tries to put it off as exhaustion. Elizabeth also informs him how Derieri mistook her for someone else, and then she tells him that she is ready to accept what he has to say. To avoid giving a real answer, Meliodas tells her that it does not ring a bell. Elizabeth saddened a little, tells him that she trusts him more than anyone else and leaves to the bar. Meliodas finally notices Ban and King above him, and Ban states how he screwed up. Meliodas asks what they're doing and if they heard the conversation, luckily, they did not hear it. Ban asks what caused trouble between them, and King teases him about needing to know how the heart of a young maiden works. This led to Meliodas punching a hole in Ban and then flicking King's head with his fingers. Meliodas thinks about Elizabeth's words and says he is not ready.

As soon as Elizabeth breaks the spell on Merlin, Meliodas busts through the door and asks what happened. He was quite surprised that Elizabeth broke the spell. Noticing that Elizabeth was worn out, he offers a back rub, but Elizabeth said she was okay, and she wanted some alone time. She starts thinking about Meliodas as soon as she leaves. Continuing with the mission, Meliodas and the others head towards the city of Corand.

During the trip to Corand, Ban asks Meliodas to sit out the mission, and Meliodas allows him to. He acknowledges that Ban is doing because of Elaine. Ban tells him that she can not handle anymore and her death is inevitable, so staying with her is what he wants to do. Before Meliodas can finish sympathizing, Ban cuts him off to say does he understand how to feels to let your lover die again. Meliodas looks away in a sad expression. Hawk busts through the door, exclaiming that there's something wrong to Meliodas. Meliodas comes in the bar to see that Elizabeth is acting strange, and she informs him that Barzad was bitten by a werefox. Meliodas becomes shocked, realizing that she's getting her memories back. After the goddess symbol appears on both of Elizabeth's eyes, she faints. Not knowing what's going on, Diane questions if Zeldris' curse moved to Elizabeth. She is then corrected by Meliodas, who says that her memories of all her previous incarnations are coming back. After Diane informs King about Elizabeth's reincarnation, she is silenced by Merlin. She points out how the captain was being cynical to Elizabeth for ignoring her. Meliodas tells everyone that Elizabeth is going to die in three days. Everyone becomes appalled, and Diane asks if he is joking. Meliodas made up his mind and decides to tell everyone about his three thousand year journey. Meliodas reveals that his curse is immortality while Elizabeth curse is perpetual reincarnation, bestowed by their parents after being killed by them. He also reveals that the only way to break their curses would be for one to get the power off to the ones who cast it, or someone with equivalent power, like Zeldris. When Diane tearfully asked what will happen if he breaks the curses, as the rest of the sins are utterly shocked and sympathetic for the separated lovers, Meliodas sadly smiles stating they will die for real this time and be forever reunited in the afterlife as he had promised Elizabeth. He comforts Diane and asks her and the rest of the Sins to remain focused on their mission.

After saving Peliot and his village from demons as requested by Gowther, the Sins arrive at the abandoned city stronghold of Corand. Someone is waiting for them, and they see it is Zeldris, causing Meliodas to rush in blind rage at his estranged brother who tells him to "wake up" and stop being deceived by Elizabeth. Despite the other's protests, Meliodas follows through but ends up getting trapped in Melascula's Dark Cocoon, who created an illusion of Zeldris to lure Meliodas in and keep him from protecting the others from her and uses an altered version of her Vengeful Return to reanimate the deceased victims of Corand who were slayed five hundred years ago, despite being only skeletons. They quickly deal with them, who are being powered by Meliodas' negative demonic energy and in desperation, Melascula attempts to force all the power into a single skeleton, but its bones are destroyed from too much power.

Meliodas taunts her failed plan but returns it with an alternate plan. She uses her magic to allow the angry souls of the city's population to possess Diane, causing her to have red and bloody eyes from having multiple souls in her body and from being extremely hostile. They use Diane as their host to attack the others and even goes as far to hurt Diane's body, but is momentarily stopped when Helbram, the one who killed the people of Corand, offers them to have their revenge by destroying the helmet he possessed.

That is not enough to satisfy their rage and the deceased souls begin causing destruction but are finally forced out of Diane when Elizabeth steps in. Melascula is angered by this and tells Meliodas she will go out there to kill her personally. Meliodas is pushed against the wall by the thought of Elizabeth dying and is forced to let go of all his human emotions and return to his original personality in order to unlock his complete power, the Assault Mode. The cost is him returning to his true self from 3,000 years ago: the most savage-hearted demon in existence.

He destroys the Cocoon of Darkness and is now a danger to anyone and everyone. Escanor challenges him and Merlin puts a Perfect Cube around them to protect the others while Escanor attempts to pacify him. Meliodas, having lost his memories, tells Escanor that a human can not talk to the greatest warrior of the Demon Clan like that, angering him. The two fight and Meliodas has a big advantage over Escanor despite it being so close to noon. Meliodas seems to have won when he crosses Escanor with Lostvayne and releases a Hellblaze through his belly. Escanor manages to recover thanks to the sun. Although Escanor takes some confidence when his power increases to 114,000, Meliodas quickly incapacitates him from a single blow. Hawk reads his power level, which reached 142,000.

The fight is resumed and although Escanor manages to disarm Meliodas and beat him, he ends up defeating him by Full Countering his Cruel Sun and giving him a coup de grace. But Escanor uses all the saved power he has stored over the years just as he becomes The One at high noon. Meliodas tenaciously launches back into battle, attacking Escanor with Kami Chigiri, without effect. Escanor is finally able to defeat Meliodas in a single attack, rendering him unconscious, but causes even worse damage to himself.

Merlin is responsible for transporting Meliodas to Boar Hat with her telekinesis, although Elizabeth insists on healing him, Merlin says that if Meliodas tries to attack them. Already in the Boar Hat, Merlin is forced to leave Meliodas unconscious when he manages to recover from his wounds in battle and then encloses him with Elizabeth in her Perfect Cube.

Prelude to the New Holy War arc
While Meliodas remained unconscious with Elizabeth inside the Perfect Cube, his old master Chandler appears suddenly, having gone in search of him. After he undid the Perfect Cube and incapacitated Merlin, Meliodas and Elizabeth are removed from Boar Hat by Diane. While the other Sins are involved in a battle against Chandler, Meliodas remains unprotected by Elizabeth, receiving one of Chandler's attacks during combat. In the end, Meliodas is returned to Boar Hat and taken away along with all the others by Drole and Gloxinia, who sacrifice themselves to stop Chandler.

Already in the Boar Hat, Meliodas begins to release a poisonous miasma that affects others, so Elizabeth decides to take him outside. Without anyone noticing, Meliodas briefly recovered the constriction and stole Grayroad's Commandment while that was in Merlin's test tube. When Chandler reaches the Boar Hat, Meliodas wakes up with Elizabeth still holding on to him as Chandler bows to him. While Ban tries to tell him that he is their comrade, Meliodas affirms that he remembers the rest of the Sins, Elizabeth, and Hawk and decides not to kill them. However, he claims that the Seven Deadly Sins are disbanded and for the shock of everyone, he declares that to save Elizabeth from the curse, he will have to become the new Demon King. After declaring a word of defiance to his father through the eyes of Hawk, Meliodas gives as his last words to his companions that the days he spent with them were not bad. Meliodas leaves with Chandler and Elizabeth, ignoring her words of to not do such a thing for her.

Meliodas arrives at the castle of Camelot and meets with Zeldris, who complains of the traitor returning to them and begins to argue with Meliodas over who will become the next Demon King. Their discussion is interrupted when Estarossa appears and says he has no interest in the throne itself and more of the fight over it but is shocked to see Elizabeth there. He instead decides he wants Elizabeth, to which Meliodas declares that both the throne of Demon King and Elizabeth belong to him alone. This triggers a confrontation between the three as Zeldris and Estarossa prepare to attack their estranged brother, but Meliodas is far too powerful for both of them together, even with the portion of their father's power that Zeldris has, and effortlessly immobilized the both of them. Elizabeth begs him to spare their lives, and he does so, with Estarossa complimenting him for returning to his old self but Zeldris is still very angry at Meliodas for his betrayal and claims he does not care about the throne and only wants the power to save Elizabeth and Meliodas does not deny the fact.

Zeldris attempts to attack him once more but Meliodas appears behind him and restrains him and whispers to his younger brother the reason for wanting the throne and Zeldris begrudgingly agrees to help Meliodas, to the shock of Cusack and Peronia. Agreeing with Zeldris, Meliodas affirms that he will not reach the power of the Demon King taking the power that he lends to Zeldris as initially planned. Zeldris begins to ask Meliodas if he plans to train to reach their father's level of power, but he complains saying there is not enough time and to save Elizabeth, he must use the most immediate solution: absorb all ten of the Commandments into himself. Revealing Grayroad's Commandment that he had stolen, in addition to those of Gloxinia, Drole, and Gowther that Zeldris already had, Meliodas entrusts his brothers to go and collect the other Commandments.

Zeldris and Estarossa both go off to claim the other four decrees while Meliodas stays behind to protect Elizabeth from Chandler and any other demons who may try to attack her. In another room, Elizabeth begs Meliodas to rethink things and ask the rest of the Sins for help. He says this is the only way but reveals the horrible truth that once he becomes Demon King, he will most likely no longer be able to stay in Britannia. Elizabeth tearfully asks what the point of breaking the curse then is, at which Meliodas realistically points out that he believes that her love for him is imprinted by the Supreme Deity, which angers and saddens her and causes her to ask why he does not just find another girl to love. Surprisingly, Meliodas reverts to his human-like form and explains that Elizabeth is the only girl he'll ever love. She happily embraces him but Meliodas then returns to his demon form and bluntly says that he felt nothing and that the promise he made to her 3,000 years ago is all he has left. Elizabeth decides that she is going to team up with the other Sins to stop Meliodas from absorbing the Commandments and angrily slaps him into a wall with Ark before she runs off, promising to save him. Meliodas quickly runs in search of her but is unable to find her.

Shortly after, Meliodas observes the light coming from the pact formed between Elizabeth and Ludociel, aware that the Four Archangels joined the battle, looking serious.

When Zeldris returns announcing his failure to recover Melascula's Commandment due to Merlin's deception, it reveals that the Four Archangels had been revived. Meliodas confirms it by affirming that Elizabeth and the Sins had allied with them, leading Zeldris to make fun of Elizabeth fleeing him. Meliodas says that none of that will matter once he has become the Demon King, as it would easily give him enough power to destroy all the opposers.

Something later, Arthur infiltrates the castle to retrieve the holy sword Excalibur and use it to free Camelot. However, it is intercepted by Zeldris and Cusack before reaching it. There, Meliodas reveals himself to the young king, telling him that this is no longer a place for humans but giving him a chance to leave. When Arthur asks him why he is with the demons, Meliodas reveals that the man he knew no longer exists. Devastated by the betrayal of the one he most admired, Arthur unleashes his fury by taking Excalibur. Meliodas and Zeldris shudder to feel the strange magic coming from the sword.

After surviving the Exterminate Ray de Chandler, Arthur manages to cut it in half with Excalibur, going on to do the same with Cusack. Surprised, Meliodas and Zeldris receive their attack as well, destroying a good part of the castle.

Once outside, Meliodas recognizes one of the techniques that Arthur used as the one belonging to the former swordmaster Craften, understanding that they are dealing with the power of Excalibur. Meliodas and Zeldris attack Arthur together, but he dodges them with speed, and they strike a powerful attack on both. However, both demons are unharmed.

After Arthur fell debilitated when not being able to support the power of Excalibur, Cusack made it in face and babbles on how to kill it. However, Merlin appears in the last minute saving Arthur with her Icicle Castle. Meliodas asks Merlin to return Melascula's Commandment, but Merlin tells him that just as he tries to save Elizabeth, his friends and his beloved are giving everything to save him. Merlin tells him not to forget it before teleporting along with Arthur and Cath.

New Holy War arc
As time passes and Estarossa does not return from his search, Meliodas decides to go ahead and absorb the five Commandments he already has, including Zeldris'. Meliodas tells Zeldris that he must deliver the other five before it is half a day after he has absorbed the others, in order to properly complete the ritual to obtain his power.

Meliodas asks Zeldris if he will be alright facing the Four Archangels without his Commandment, but Zeldris is more concerned that Meliodas will fulfill the promise he made to him, to which Meliodas affirms that he will fulfill it once he absorbs the Ten Commandments and becomes in the Demon King. Meliodas proceeds to absorb the five Commandments, after giving Zeldris an apology for the kind of older brother he was.

Although Merlin managed to stop the time of the cocoon Meliodas manifested, her efforts are in vain as Meliodas, who has already completed the process of absorbing all the Commandments, becoming Demon King, broke free before the spell took place. As his powers completely engulf the surroundings in darkness, leaving everyone shocked by his overwhelming strength, Elizabeth shakily asks Meliodas if it is him. Meliodas, now looking like an adult, smiles.
