Ban/Plot

Introduction arc
Ban's wanted poster is displayed on a board inside the Boar Hat.

Forest of White Dreams arc
Ban is first mentioned by Gilthunder to have been imprisoned in the Baste Dungeon. After Meliodas and Gilthunder's fight, Ban is shown to be chained to a prison with guards that are guarding him stating that he has not moved or eaten any anything since his imprisonment, which was five years ago.

Baste Dungeon arc
When he hears that Meliodas was alive, Ban, wanting to meet his captain, easily escaped from his prison cell, and was immediately confronted by Jericho, who tried to kill him. Ban easily dodged all of Jericho's slashes and even purposely let her cut his hair. When Jericho is shocked that he dodged her attacks despite his severe wounds, Ban shows her that they have already healed, and points to his scar as the only scar he ever received.

Ban then took Jericho's armor and clothes in an attempt to find decent armor before leaving. Disappointingly, he discovered the armor to be too small, after which Ban came across a guard looking lustfully at a captive woman. He glanced at her, showing some interest, and proceeded to smash the guard's head into the bars. He then entered the cell by bending the bars, and told the woman that she "[was] his", before stealing the dagger that she had hidden in her clothes. He commented on its good quality and tested it out by cutting her chains. She thanked him for releasing her, and requested the dagger back; however, he refused and declared that it belonged to him, which greatly frightened her.

Jude arrived, intending to kill him, though Ban merely greeted the Holy Knight in return and asked for the reason he wished to kill him, with Jude answering that he had no more use for him since he had already fulfilled his role as a bait for Meliodas. Engaging Jude in combat, Ban was quickly stabbed in the chest by one of the Holy Knight's thorn-like weapons. He, however, explained that he had actually let himself be captured five years earlier, and the reason for it. After removing the weapon from his chest, he easily stabbed Jude in the chest, expressing his excitement about the Holy Knights declaring war on the Seven Deadly Sins.

Together with the frightened Sennett, Ban left the Baste Dungeon and encountered Meliodas, Diane, Hawk, and Elizabeth. He and Meliodas then greeted, high-fived each other, and then started arm wrestling, which resulted in the entire dungeon being destroyed. Afterwards, he told Meliodas that he was glad to see him again. With the dungeon destroyed, he, along with the others and the imprisoned villagers, headed to Dalmary Town, where he went off on his own, stealing a set of red, studded clothes from a random villager. Later that night, Ban was introduced to Elizabeth and noticed that Hawk is a talking pig, which greatly shocked him. During the party, he started drinking and even rode on top of Hawk. Together with the rest of the group, he looked up at the sky to see it filled with crossing shooting stars, falling asleep on Hawk soon after.

Capital of the Dead arc
Three days later, Ban, along with the rest of the party, left Dalmary Town, Elizabeth's recovery having caused their delay. As he and Meliodas decided upon their next destination, they are abruptly stopped by two Holy Knight apprentices. Ban offered to quickly kill them, only for Meliodas to stop him, and trick the apprentices instead. However, the two soon realized the Sins' identity due to Diane. Before they can take action, they were suddenly attacked by a black hound, who quickly killed the two apprentices. Though Ban tried to frighten it, it instead grew bigger, since black hounds are able to change their size depending on how frightened they feel. However, before he could proceed to kill the creature, Meliodas used his broken blade to scare it away, and then declares their next destination to be the Capital of the Dead, in order to search for King, whom Ban expressed disdain for.

In the town nearest to the Necropolis, Ban was assigned to cook in the Boar Hat, though he expressed several complaints. After he escaped from work, Ban headed into town and discovered a little girl, Ellen, whom he mistook for his dead lover "Elaine". She suddenly collapsed, leading him to rush by her side. Ellen's brother, Luigi believed that Ban was going to take her away, and attacked him. When he learned of the truth, he apologetically questioned Ban as to how he can "erase his sin". Ban responded that a real sin can never be erased. As soon he finished his statement, Ban was then suddenly stabbed in the chest with a spear by King.

Ban questioned his assailant's identity, to which King replied, calling him, "Ban, The Undead", and revealed that Ban had killed the Saint of the Fountain of Youth to gain immortality. The two then engaged in battle, and after it continued tensely for a while, Ban prepared to utilize a special ability, which Meliodas quickly stops. The Sin of Wrath and Diane recognized King immediately, despite his changed appearance, with Ban being completely shocked and unable comprehend how the boy he fought was actually King. Later, after King escaped, Ban cooked a meal for the children inside the Boar Hat, and children informed them that King had tried many times to enter the Capital of the Dead. In regard to entering it, Ellen then recited a riddle, stating that a priceless memory shared with the deceased will open the path to the capital. Possibly understanding it, Ban thanked them, and the group headed to the entrance to the Capital.

At the location of the entrance, the group notices flowers to have suddenly and mysteriously bloomed; the petals of the flowers then swirl around them in a circular fashion, transporting them to the Capital of the Dead. Ban immediately notices a girl and chases her, with King, in turn, following Ban. As he is chasing the girl, King provokes Ban, leading the latter to attack the former. However, King easily dodges Ban's attacks, convincing Ban of him being King. King narrates how he came to discover his hometown to have been burned to the ground, then trapping Ban by transforming his pillow into a giant stuffed bear, and angrily reveals that the Guardian Saint whom Ban killed was his sister. When Ban, in response, declares that he is immortal, King uses a form of his Sacred Treasure that petrifies all whom it impales. Ban's skin around the impaled area is shown to have petrified.

Soon, Ban turns completely into a statue. As King begins to leave, he notices spheres of light approaching Ban, and as he recognizes the spheres to be Elaine, his sister and the Guardian Saint of the Fountain, she kisses Ban in order to break King's curse. They exchange their greetings, when King confusingly yells at them, questioning whether Elaine was still angry at him. The three are distracted by a huge explosion some distance away. Noticing that a Holy Knight has arrived, Ban proceeds to head there, but only before telling Elaine that he will definitely make her his someday. Ban then enters the battle and assists Meliodas and Diane by appearing to immobilize the Holy Knight who follows them to the Capital of Dead, Guila, by using his ability, Snatch, on her rapier.

Guila's retaliation heavily wounds him, but he regenerates within a few moments, leading her to comment upon his immortality. As the battle continues, Guila stabs him in the neck while commenting on how weak the three Seven Deadly Sins were. However, King then arrives and attacks Guila by stabbing Ban through his back with his spear. King explains that he has arrived to help the Sins, to which Ban sarcastically thanks him, and adds that this is for Meliodas and Diane, and also due to Elaine's feelings for Ban. Though Ban initially seems to be angered by King wanting to fight Guila alone, he quickly complies.Ban and the two watch as King defeats Guila with ease, and as, when she uses the element of surprise to attack King from behind, Meliodas stops her repels her attack. As soon as she is defeated, everyone's bodies start disintegrating, the Capital of the Dead having begun to reject them due to them being alive and not belonging there. Ban says his final goodbyes to Elaine, before returning to the living world along with the rest.

After returning to the living world, they find Guila's real body, with Ban suggesting killing her right then. Later, Ban and King find Ellen and her brother, who reveal themselves as ghosts that guide people who shared priceless memories with the dead, such as them, to the Capital. The both then disappear, but only after telling Ban that his cooking was delicious and thanking them, to which Ban, smiling, also thanks them in return. When King is told that Elizabeth is a princess, and he transforms himself into his older and fatter form, Ban is shown to be extremely surprised. Later, Ban is shown to be drunk when King asks him, Diane and Meliodas as to what happened to their sacred treasures, with which, the three would have been easily able to defeat Guila. Ban drunkenly responds that his was stolen during his imprisonment, much to King's irritation. He then looks on as King explains to Hawk the significant increments in the Seven Deadly Sins' power, wielding a Sacred Treasure can create.

Vaizel Fight Festival arc
The next day, Ban is shown to still be drunk at the Boar Hat. He is later left behind along with Diane while Meliodas, Elizabeth, King and Hawk go to Byron because of his wanted poster's image's accuracy and her size as a giant. Later, Ban accompanies Meliodas, Hawk, and King into Vaizel, while wearing an apron due to his shirt having been destroyed in the Capital of the Dead, since Meliodas speculates a sacred treasure of the three Sins to be among the objects sold in the annual flea market of the town. There, a drunk elderly man directs them to the annual fighting tournament, whose reward is the weapon "that no one can use", which is revealed to be Diane's Sacred Treasure, Gideon. Ban and Meliodas eagerly join the tournament; Ban enters the names of the three, including King, under false names, and against King's will.

During the preliminaries, Ban, while commenting the battles to be boring, easily defeats many other fighters and stole a new shirt similar to his previous one from an unfortunate man he just met. After preliminary ends, he is shown to be among the eight fighters who have advanced to the main tournament, along with Meliodas and King. As their advancing is announced, he mocks King for winning in a cheap fashion by using his flight abilities. During the determination of the match-ups, he is revealed to have entered King, himself, and Meliodas under the names of "Old Fart", much to King's annoyance, "Baan", and "Meliodafu". Howzer, a Holy Knight almost discovers the identities of the latter two from their physical traits, but in his naivety and stupidity, does not see through the obvious aliases. Ban, standing among the audience, watches the battle between Griamore and Matrona. After the latter defeats the former, causing her hat to fall off and reveals her face, which is identical to Diane, Ban looks on bewilderingly. Ban similarly looks on while Howzer and Taizoo fight, and also explains to Meliodas and King about Taizoo losing against the Holy Knight. After the third battle of the main tournament, between Cain, the elderly man who directed the four to the tournament, and King ends with the latter losing, Ban finally readies himself for his battle against Meliodas.

As their battle begins, Meliodas compares the ring, and the tournament's rules of a fighter being disqualified if he is pushed out of the ring, to "something" long ago. Telling Ban that he will remember soon, Meliodas punches him with great strength in his face. This reminds him of the mentioned episode: Meliodas and Ban's first meeting when the latter was still imprisoned, for supposedly burning the Fairy King's Forest and killing its guardian, that led to him joining Meliodas. Ban seems to have been pushed out of the ring, but regains his balance, and proceeds to exchange a series of attacks with Meliodas. One of Meliodas' retaliations sends Ban crashing into the ring, and even breaks the Great Vaizel Rock, on which the ring is located. Ban heals himself instantly, much to the audience's surprise, and continues to fight. As their battle continues, Meliodas punches Ban again; however, he then falls down to his knees, due to Ban having used his ability, "Snatch". Ban immediately heals himself, and attacks Meliodas again. When the latter tries to retaliate, he appears to have weakened. As Ban displays his increased speed, Meliodas attacks him again, but as before, is easily defeated, and seems to be continuously losing his stamina and the battle as the fight continues. This leads King to explain that Ban's ability, Snatch, enabled him to "rob" not only physical objects, but also physical abilities such as speed and stamina; the reason why Meliodas was on his knees without receiving any damage was that Ban had "robbed" him of his physical abilities. As the battle continues in Ban's favor, Meliodas, lifting Ban with one hand, smashes him repeatedly on the ground. Ban, however, is then revealed to have stolen Meliodas' physical strength during the attack. Ban, wanting to test his strength now, punches Meliodas, but is stopped by a single punch. Ban stops himself from being pushed out of the ring, and wonders how bottomless his captain's powers are.

He, again, instantly heals his wounds, Ban states that since the battle would not end by stealing of speed and strength in small doses, he will now rob all of Meliodas' abilities. Meliodas attacks Ban with a barrage of punches, and the latter continues stealing the former's abilities. In the end, all of Meliodas' abilities are shown to have been stolen before he is able to defeat Ban, as the Sin of Greed smirks while standing over his collapsed and weakened captain. Ban tests the strength he has stolen by swinging his hand, the mere resulting air pressure creating a crater on the ground.

Ban questions Meliodas if he will give up, or be utterly defeated; Diane yells at him that if he further harms Meliodas, she will not forgive him and will cut off their ties. The Sin of Wrath refuses to give up, and states that he will win. Diane then states her hypothesis that Meliodas is baiting Ban to delivering his most powerful blow, and will then reflect the blow with Full Counter back at Ban. King, however, explains that doing so would be impossible - Full Counter can only reflect "power" attacks, and is useless against indirect attacks such as Ban's Physical Hunt, or an ordinary punch. Despite Elizabeth's pleading, Ban punches Meliodas. In the midst of the resulting dust and debris, Meliodas, who now mysteriously has a strange black colored mark on his forehead, and his eyes colored black, crushes Ban's hand, then proceeding to send him flying out of the ring with a single punch, thus defeating him.

Ban laments his defeat, and his having forgotten about what, he calls, his captain's "trump card". Hawk then unwittingly carries Ban to the ring due to him feeling his body to be very heavy after using "Physical Hunt" Ban, still laying on Hawk, watches Diane and Howzer's battle. During Meliodas and Cain's battle, when King and Diane wonder as to Meliodas and Cain's relationship, Ban instructs them to stop, citing the third law of the Seven Deadly Sins, which states that a Sin shall not question of the sin of an another member. Sometime afterwards, during the beginning of the final battle of the tournament between Meliodas and Diane, Ban is shown to have paid some women to cheer for Meliodas flirtatiously and erotically, which would enrage Diane into fighting him seriously. This was since the two fighters were intending to end their fight quickly by Diane letting herself be defeated. Ban enthusiastically watches Meliodas and the enraged Diane fight. Some time afterward, Meliodas, stopping the fight, declares his identity, and that he will now be taking over Vaizel. Ban and King enter the stage and are immediately recognized due to their appearances. Meliodas continues, ordering everyone to leave Vaizel in one minute, lest they be massacred. A few brief moments later, several gigantic, and explosive flares rain down on the town. The attackers are shown to be Guila, Jericho, and another Holy Knight, Marmas. Elizabeth then understands the Sins' actions: the four had threatened the civilians to leave to have then evacuate. Meliodas notes that the attackers are now much stronger than before, instructs the other three to separate. While the attacks continue, Ban, is sent crashing onto a building by a surprise attack from Jericho. He expresses his enthusiasm to fight, but questions Jericho whether they have met before, and she declares that she will carve her name into his heart.

Jericho's subsequent introduction reminds Ban of her. He, believing that she is male from their previous encounter, questions whether she cross dresses, and kicks her away. Much to his surprise, his wound does not heal despite his regeneration abilities. Jericho, stating that the Deadly Sins are no match for the "reactors", attacks Ban as he dodges. Walking towards Ban, she states that she no longer has to pretend to be a man, since she was now powerful. She kicks him on his chest, and spreads a drop of his blood, which spurted on near her lips, as a substitute for lipstick, she states that Ban has made her into a woman. Sometime later, after Veronica, Elizabeth's older sister seals Meliodas with Goddess Amber, and tries to forcibly bring Elizabeth back to the capital, Ban wakes, and quickly takes Veronica hostage. Griamore demands for him to let her go, in return to which Ban asks for the spell on Meliodas to be undone, and for Elizabeth to be released. However, he is abruptly slashed from behind by Jericho, which allows Veronica to escape.

Ban then overhears Guila informing Griamore about Hendrickson's goal, resurrection of the Demon Clan. Enraged due to his experiences with a demon, Ban attacks Jericho, but is defeated quickly again. As Elizabeth then pleads for Meliodas to rescue her from Guila, the Goddess Amber shatters, releasing a black substance, whose aura recognizes as similar to the demon he killed in the Fairy King's Forest. Meliodas proceeds to cut off Guila's hand to regain his broken sword, leading Jericho to utilize an Incantation Orb to heal Guila, with Ban recovering along with them and then stealing the rest of the Incantation Orbs they possess. Angered, Jericho prepares to attack Ban, when he yells out to them to prepare for Meliodas' attack which knocks them both away. The rampaging Meliodas slices Ban in half and completely destroys the nearby terrain.

As Elizabeth and Hawk watch in horror as Meliodas is defeated by Helbram, Ban grabs King and tells Elizabeth that they have to retreat. Elizabeth refuses to leave Meliodas behind, but Ban grabs her and tells her it's too dangerous to be around, proceeding to run away from the fight. Soon after, Diane finds the wounded Meliodas and, in her rage, ends up completely destroying Vaizel with her Sacred Treasure Gideon, while Ban and the rest are running away. After Diane saves Meliodas, Elizabeth and Hawk watch in shock at what happened to Vaizel, while he reminds them how he said that it was too dangerous for them to be around.

Armor Giant arc
After the Boar Hat stops at a unknown location, Ban and King start training together to improve themselves after the events at Vaizel. While they are sparring, Ban asks King if he was taking him lightly and tells him he should try to act like he was trying to kill him, but King tells him he can not kill someone who is immortal, to which Ban reminds him that he could stop him from fighting like he did in Capital of the Dead. Ban then tells King that Jericho's slash wounds did not heal at all, something that King finds odd, and wonders if it could be a power that stops time at the wound or an illusion power that creates a sensation of pain.

King then tells Ban that he is not acting like himself and could be trying not to think about something, with Ban quickly appearing behind King and tossing him toward a boulder in response, with King barely stopping himself from crashing into it. Ban then tells King that he just wants to crush the Holy Knights and take back the kingdom as soon as possible. King is further surprised to see Ban caring about other people's business to which Ban tells King that he feels the same, but King reveals that he wants to stop the Holy Knights because he wants to help Diane.

Ban then reveals to King that he wants to get the Horn of Cernunnos which greatly shocks King because it is the treasure of the kingdom. He asks Ban if he is planning to steal it, but Ban answers that since he is going to save the kingdom, the horn would be a good reward for him. King wonders aloud about the legend of the horn, which is said to have the ability to communicate with the Goddess Clan, with Ban revealing his intentions to use it and ask a Goddess to revive Elaine from the dead, claiming that it would not be a trouble for one. Ban then yells to King that he should take him more seriously, something that King agrees with. While sparring some more, King says to Ban that the main reason he is not acting like himself is because of Meliodas' change at Vaizel and how his power resembled Guila's and Jericho's, but was much more sinister.

King starts to think that Meliodas could be from the Demon Clan but is stopped by an angered Ban, who yells at King, saying that Meliodas is not the same as the monster. King is confused as to the monster Ban is talking about, but Ban does not explain further. He tells King that Meliodas took him in, despite being an outcast and a bad person. Ban tells King that only two people in those world accepted him for who he was, and those were Elaine and Meliodas. Ban then tells King that Meliodas would never kill anyone, no matter how bad they were, saying he is too naive to be the same as the monster he fought in the past. Ban and King later meet with Diane and Elizabeth who went to find Meliodas, and later stands at the opening of the mountain Meliodas split in two, listening to his speech with the others.

King and the others later meet up with a group of kids who are role-playing as them, and later befriends them. Ban ends up chatting with Armando, who apologies to Ban for the trouble they are causing. Ban replies that it does not matter if they want to fool around, but warns that they should not role-play the Seven Deadly Sins since he would not help them if they got into trouble with the Holy Knights. Armando then tells Ban that it's odd how Meliodas talks like an adult while being the same age as Pelliot. Everyone is later informed that a group of Holy Knights was spotted at the mountain, to which the kids set out to find them. Later the Deadly Sins overhear a dying knight, screaming that there is an Armored Giant at the mountain which easily annihilated his group. Meliodas then reveals to everyone that the Armored Giant is the Goat's Sin of Lust, Gowther.

King, Meliodas, and Ban head to the forest to find Gowther, where they see him having a standoff against the Dawn Roar. The standoff is broken when Pelliot arrives at the scene and attacks the giant, before being saved from death by Armando, who is smashed by Gowther to the ground. The Deadly Sins then head to the battlefield. Ban rushes toward Weinheidt to stop him from shooting down Gowther with his arrow, however Weinheidt turns out to be an illusion, informing Ban that the Dawn Roar knew about them hiding in the forest. The real Weinheidt, hiding in a pile of dead bodies, shoots Gowther with a powerful magical arrow, but the arrow is caught midway by Armando, who then reveals himself to be the real Gowther, to the shock of the Sins.

Excited, Ban walks toward Gowther and tells him he always thought he was a big old man under the armor. Gowther expresses his surprise that Meliodas did not change over the years, which Ban points out he does not look surprised and did not know the little kid is King until he changed back to his fat form. Once Gowther offers the giant head to the Dawn Roar, and they leave, Gowther tells everyone that the monster was most likely human, which shocks them. The monster later gets up despite being headless and Gowther further reveals that it used to be a Holy Knight.

The beast almost smashes Meliodas and Ban with it many finger fists, but the latter dodges in time and sent out several attacks against the beast's head, but the beast is not effected and sends them flying. King saves them with Chastiefol, which he then sends to fight the beast, but it is easily defeated by its ice breath. Meliodas and Ban decide to use the weapons of the dead Holy Knights and Meliodas charges toward the beast with a sword and a shield. When Meliodas uses Enchantment on the beast, Ban tells Meliodas to finish it, and becomes upset when Meliodas does not kill the beast due to hearing it speak.

When Meliodas is saved by Gowther with his strange arrow ability, Ban uses his whip to pull Meliodas away. Ban then scolds Meliodas for not killing the beast, but Meliodas explains that the beast is still alive, but Ban tells him to stop being naive. Gowther then uses one of his powers, Invasion, where he traps the beast into an illusionary world which his heart most desires to see, Ban says that they should kill the beast but Gowther responds by saying that the Holy Knight did not wish to be born like this, and therefore, he is unable to kill him. Ban decides to kill the beast himself until Meliodas stops him, saying that the beast is still partly human, but Ban does not listen and removes the beast's heart with his whip. Meliodas gets upset with Ban for killing the beast, but Ban tells him that they should have put it out of his misery, to which Meliodas responds to why not kill him. King then points out that the beast is mumbling something despite having lost its heart and start releasing a lot of power. Ban then wonders why removing the beast's heart did not work and realizes that it's a demon.

While Meliodas tries to reason with Dale, Ban pushes him out of the way and gets cut in half. After Ban heals himself, he punches Meliodas and tells him he should stop being naive or everyone they know will die. Elizabeth then appears and offers Liz's Sword to Meliodas, which he finally uses to slay the beast in one hit. Ban then goes to search the body where he finds a strange planet which attempts to attack him, but he crushes it with ease and overhears Dale thanking him. The Deadly Sins later take Gowther to meet with Diane and hold a celebration party. Gowther later uses Invasion Search Light on Ban, which reveals that Ban robbed Diane and King's strength during a past battle while drunk, with Diane angrily squeezing him for doing so.

Kingdom Infiltration arc
As Meliodas explains his reason to head to Liones and get his sword back, a mysterious Holy Knight appears out of nowhere and takes Elizabeth, saying she was the last key to the Coffin of Eternal Darkness. After his initial outburst, Meliodas orders Diane to toss him to Liones, with Ban and Gowther deciding to tag along for their own reasons. Diane tosses the trio toward Liones at full speed with Ban screaming that he might die of such speed. Soon after, Meliodas, Ban and Gowther land near Liones and start running toward the kingdom, with Holy Knights aware of their arrival trying to stop them. Meliodas tells Gowther and Ban that their mission is to save Elizabeth and to keep the fighting to a minimum. Ban wonders if Meliodas will be going all out, with Meliodas responding that he will.

The Deadly Sins briefly stop when they feel a large power coming from the southern gate of the kingdom, which turns out to be the Camelot army led by Arthur Pendragon. Later, the trio continue to cut through the Holy Knights as they attempt to break through to the castle. Deciding to end this with minimal bloodshed, Gowther uses his Sacred Treasure Herritt to overwrite the memories of the attacking Holy Knights and turns them into their allies. Gowther explains his technique to the bewildered Meliodas and Ban who then warn him not to use that on them no matter what, which Gowther complied. The trio sneak away from the Holy Knights and go into hiding to figure out a decent strategy. Ban tells Meliodas that they should head to the Liones castle, because in fairy tales, the princesses always get locked in underground prisons. Meliodas agrees to the plan and heads out to the castle as Meliodas promise to save Elizabeth. The trio then sense a battle going on by the south gate, which changes Meliodas' mind, and he decides to head over there, thinking Elizabeth could be there.

The trio see Ground Gladius suddenly rise in middle of the kingdom, and realize it's one of Diane's abilities and collectively wonder if she's in trouble. Gowther offers to go and help her while Meliodas and Ban save Elizabeth. When Great Holy Knight Dreyfus makes an announcement of the Sins' presence in the kingdom, Ban calls him bastard as he and Meliodas keep running to the place where Meliodas believes Elizabeth might be.

As Dreyfus is under Gowther's Nightmare Teller, a past version of Ban is seen being completely drunk, earning an angry glare from King.

Meliodas and Ban stop in their tracks when they see giant roots attacking a section of the kingdom where Diane, Gowther and King are located. Ban asks Meliodas if he can sense it, which Meliodas nods to as he mentions that Diane and Gowther's powers are fading, but King's rose to an invincible level. Ban and Meliodas then decide to split up to cover more ground, with Ban heading off to the castle, and Meliodas to fight Hendrickson.

While inside the castle, Ban sneaks around, so he would not get caught by the Holy Knights. He spots a lone Holy Knight, and before he is able to call for backup, removes some Holy Knight's teeth and asks for information, threatening to remove his ribs too if he did not comply. After a successful interrogation, Ban leaves the Holy Knight unconscious and goes off to a wall, and turns a lion head around so a secret entrance is revealed. Ban walks inside the entrance and finds Liones' treasure, the Horn of Cernunnos, and is surprised by its great size. Ban calls out for a Goddess and asks if they could exchange his own life to revive Elaine from the dead. Ban then hears a voice and is shocked to see Hawk standing of the Horn. After Hawk explains to him how he ended up there, he suggests to leave and save Elizabeth, but Ban tells him to go ahead without him.

Ban thinks that he can not just give up like that, and that there must be something he can do to revive Elaine, and at that moment a voice speaks from the Horn, telling him that there is indeed something he can do. The Goddess tells him that due to the Ancient War, they lost their power and will need time to regain their physical forms. Ban is skeptical about the Goddess so easily agreeing to take his life and bring Elaine back to life, but the Goddess tells him that she will not take his life, but will ask him to do a mission, and if he succeeds, she will bring the fairy back to life. Hawk protests, telling Ban that it sounds shady, but receives a double shut up from both Ban and the Goddess. Ban then tells the Goddess that he agrees to do the mission. The Goddess tells Ban that his mission will be to kill a certain man. She also tells him that this will benefit the four clans, and asks him if he will accept. Ban tells her that he had already said he will do what she wants. The Goddess then reveals that the one he must kill right now goes by the name of Meliodas from the Seven Deadly Sins, which deeply shocks Ban.

Ban later appears at the battlefield where Elizabeth had just been taken by Hendrickson, armed with a three-section staff. When Ban and Hawk approach Meliodas, Meliodas and Hawk agree to go rescue Elizabeth and ask Ban for help. However, Ban starts to attack Meliodas to the latter's shock, ripping his arm off. They exchange blows, and Meliodas snatches his arm back, using his Demon powers to reattach it to his body. As Ban witnesses Meliodas' ability, he asks Meliodas if he is from the Demon Clan, to which Meliodas does not respond, with Ban taking it as a yes. As they battle, Hawk tries to stop Ban by saying that if he killed Meliodas, they will no longer be friends. Ban responds that they were never friends which shocks Hawk, however he tells Hawk if he wants to stop him, then he should try, showing that despite choosing Elaine, he does not want to kill Meliodas. As Meliodas is driven against the wall in the middle of the fight, and Ban reveals that the Goddess Clan promised him to revive Elaine if he killed him, Meliodas understands Ban's intentions, as he had always heard him sleep talk about Elaine, and decides to accept death by Ban's hand. Ban was surprised at this sudden event, but decides to do as Meliodas wishes, saying he will never forget about Meliodas, telling Elaine to wait just a bit longer. As he is about to kill Meliodas, the latter jumps up and head-butts him in the face, breaking his jaw into pieces. Ban grows furious at Meliodas, asking why would he accept Bans offer, but then attacks him. Meliodas tells Ban that he did say he is okay with Ban killing him, but did not say he would not fight back. Meliodas then tells Ban that Elizabeth thinks nothing of sacrificing herself in order to save Liones, and knowing that, he can not just die. Meliodas tells Ban that despite what he is doing, Ban will always be his friend, no matter what, but like him, he's got things that he can not give up on. Hawk then confronts Ban, asking if he will really do what the horn ordered him to do, asking if Meliodas is not his friend. Ban tells Hawk that Meliodas is his greatest friend, but he wants Elaine to come back. Upset by this, Hawk says that if Elaine does 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 knew 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.

As Meliodas ordered Hawk to carry him to Elizabeth's location in Merlin Old Castle, Ban told Hawk to take care of Meliodas while he helped out with the current problem. Ban found the poisoned Gilthunder who he grabbed and tossed at the demonic Jericho which alarmed Margaret Liones and Vivian. Diane was annoyed at Ban's actions until he tossed a Hyper Recovering Spell he got from Vaizel at Diane and Gilthunder which healed them quick, but quickly realized that he should have used it on Meliodas. Ban then told King to take his fight against the revive slaved Helbram seriously due to Meliodas ordered. Ban faces the Hybrid Demon Jericho who her brother, Gustaf begged him not to kill her while Jericho plead to kill her as she does not want to live as a monster for her live. Ban grins as he said he will end her life as he used his three section staff to strike her. But, instead of killing her, Ban remove a strange "plant" which he destroyed as Jericho return to normal while Ban said he ended her life as a Holy Knight, saying that she should not hold it against him. Ban and King teamed up to stop the Hybrid Demon in Liones while the others help Meliodas to save Elizabeth.

Ban rejoins the other Deadly Sins member at Merlin's old castle to face Hendrickson in the final battle. While the Deadly Sins, Meliodas, King and Diane were fighting against Hendrickson, Ban questions Gowther how Hendrickson gain demonic powers which Gowther explains that Hendrickson gained them through a demon corpse (As Guila told him). Ban was surprised to hear what Gowther said until Hendrickson slams Ban against the wall where Ban discovers the Red Demon corpse that he slayed many years ago. Ban walks toward Hendrickson and furiously slams him against the wall as he asks where he got the corpse, and the wall breaks down to reveal the Red Demon corpse. The Deadly Sins were shocked to see the Red Demon corpse as Hendrickson explains that he found it in the Fairy King Forest long ago and how much of a blessing it was to him. Hendrickson used the power of the Red Demon and nearly stabs the Deadly Sins, However Ban uses this opportunity to get closer to Hendrickson and slam him to the ground while furiously telling him that he can not beat him since he was the one who killed the Red Demon.

After the king, Bartra Liones returned and thanked the Deadly Sins, Ban goes to grieve over Hawk death, feeling terrible for saying that the two were not friends. However, Gowther logically explains to the Fox's Sin of Greed that if captain had died instead of Hawk, their chances of victory would have been diminished and Hawk's death did not even affect the fighting prowess of the group and considers not much of a loss.

Jericho complains about the room they're given but Ban tells her its on higher standards than the usual in this city. He tells her that he lived in this city when he was a kid, and before Jericho could ask more his attention was dragged by the ruckus outside where someone was getting beaten up. Jericho wonders if they should help him but Ban tells her to not stick her nose in it. However, as soon as he heard that person is the one who revived a dead person, Ban beat up the bandits and took the man to the inn, throwing him to the floor who is revealed to be a Werefox.

Ban speaks out how the Beastman escaped the bandits' abuse and proceeded to return Jericho's wallet, which the Werefox had stolen. Ban asks the beast if he revived a dead person but the Beastman denies that rumor, but collapses to the floor a moment later and is quickly rushed to bed. The beast tells them that they, humans will never understand what it is like to live off stealing alone, which causes Ban to reminisce.

Whilst Zhivago told his story, Ban listened carefully until the Beastman mentioned his two sons and how he had betrayed one of them. After he told his story, Ban reassured the ill Beastman that he is not angry at him nor did he ever despise him for a moment, which startles the Beastman whom Ban recognizes as Zhivago, his idol father, embracing him soon after.

Ban begins to protect Jericho from Elaine, as he tries to persuade Elaine to stop. After hearing Jericho's speech, Elaine cries until Ban embraces her. He reminds her of his promise that he would one day make her his, and reassures her that they will go on a journey together. Relieved, Elaine loses consciousness in Ban's arms. After hearing a mysterious voice which states that Elaine would die soon, Ban turns to face both Galand and Melascula. He pieces together what has happened and swears that he is going to kill them for what they did to Elaine.

Ban pulls his Three-section Staff towards him, but Galand cuts him in half before he has a chance to move. After knowing of the commandment's defeat by Meliodas, Ban comments on their mentioning of Meliodas' relation to the Demon Clan. A furious Galand asks how he's still alive, to which Ban replies he is immortal. Galand tries to kill him once more, by crushing Ban's head, but, the latter recovers almost instantly. Galand then offers Ban to hit him once in honor of his feats, as Ban prepares his Hunter Fest, robbing Galand of his power and delivering a massive kick to the latter's gut. Ban continues his assault on Galand and soon shifts to attempt a hit on Melascula. Galand continues to attack Ban to no avail. Melascula deduces that Ban's ability, Snatch, will wear off soon and that he is currently beyond Galand's level. Ban continues to provoke them as he feels his body's exhaustion kicking in.

Ban then switches his attention to Melascula who traps him in her Antan no Mayu. She explains that she is the "Faith" of the Commandments and impressed by Ban's strong faith while facing Elaine's rage moments ago. She knows that she can not kill him due to having an immortal body, however she reveals that his soul is still the same as a Human's and can be killed - forcing it out of his body. Galand asks for his soul but Melascula refuses, but he still proceeds to jump up and devour his soul.

Ban's body is then seen using Fox Hunt, catching the commandments off guard and ripping out one of their hearts.

After traveling a few dozen miles, Ban collapses due to exhaustion and explains hat he was saved by Zhivago, who appeared before Galand and was eaten in Ban's place. After asking Jericho to take Elaine and run, she refuses and instead, she promises to carry them to safety.

As Jericho carries Ban and Elaine away, Galand and Melascula start toying with them by throwing boulders at their location. They miss twice, before the third one hits the ground and send the group tumbling off a cliff. Thanks to Elaine, the three of them land safely near a dark cave. Inside the cave is an open bar with a lone bartender inside. As they enter, the bartender greets them to his store: "My Sweet Gluttony".

The bartender who recognizes Ban backs away until Jericho tells him that the Seven Deadly Sins are no longer considered criminals. The bartender urgently asks about Merlin's condition, but is left hanging as Galand and Melascula find the bar. Ban, Jericho, and Elaine quickly hide from the two commandments.

As night shifts to day, the bartender, who reveals himself to be the Lion's Sin of Pride, Escanor, decides to play Galand's deathmatch game. After a strong swing from Galand, Escanor intimidates Galand and causes him to flee breaking his own commandment and turning him to stone. After his small battle with Melascula, he turns to Ban and orders him to stay put... to which the latter states even if he could, he could not.

Meliodas understands that being only the emotions of the real Meliodas, he will only end up delaying Ban. Even so, Ban affirms that he will carry with him. He tries to use his Fox's Hunt on the creature, but it returns to avoid it with his speed. Ban begins to chase, being unable to catch it.

Taking a rest from the persecution, Meliodas asks him how much he must have suffered in Purgatory with a body of flesh. Ban tells him that he lost count of how many times he was about to surrender, spending the first hundred years reliving from burning to ashes, frozen to the bone and rotting from deadly poisons. However, after two hundred years, he ended up getting used to all that, even being able to sleep in the process. There, Ban manages to wait and use a quick blow to finally kill the creature.

While making new clothes with the skin of the creature, Melidoas thanks Ban saying that he is incredible. Ban tells him that when Merlin told him that the Demon King had captured him, he hoped he was locked somewhere. Melidoas explains that at first it was like that, but in the end he managed to escape but ended up giving up on finding a way out and became a monster. Ban asks him if the Demon King was okay with letting him wander with the possibility of finding the exit, giving Meliodas with the conclusion that the Demon King is the one who watches the exit of the Purgatory.

After finishing their new clothes, Ban and Meliodas decide to start their escape mission. While touring the Purgatory, Ban asks Melidoas what he wants to do first after having returned to the real world. Meliodas tells him that he wants to break Elizabeth's curse and drink enough barnya to fill his eyes, and Ban says that he will revive Elaine and drinks enough aberdeen to bathe in it.

Several monsters attack them, ending Meliodas unable to fight and trapped by them. There, Ban manages to save him and uses Crazy Hunt to kill all the monsters. Noticing the presence of another, Ban kills him from a distance, affirming that the flesh of that creature is the most delicious.

While they eat the creature's flesh, Ban mentions that they do not really need to eat being an immortal and a soul in a fake body, but that doing it really makes them feel alive. Meliodas says that even though they have spent five hundred years without seeing each other, he does not stop being surprised at his ability to adapt to things. Ban says that he had no other option, but Melidoas says he is not surprised that he tried to adapt, but that he could. Ban mentions that burns and frostbite have stopped affecting him and that he can breathe rotten air without problems. Meliodas declares that he is the only human who has survived so long in the Purgatory and retained his rationality, Ban says that it is due to his immortality, but Meliodas remarks that with that it would not be enough. Ban believes that it is because he was raised in a horrible environment as a child, but Meliodas does not believe that he is related. Meliodas tells him that his body and soul have been explosively transformed by what he has experienced, and that everyone on the other side will be greatly shocked to see him. Although he does not feel it himself, Ban hopes to be strong enough to face the Ten Commandments. Meliodas laughs at his claim, causing Ban to get angry.

Ban points out that he now knows the true size of his power by not seeing him suffer the wounds that his immortal body suffered, claiming that when he returns to his body, no one can oppose him. Ban and Meliodas begin to talk happily about what they will do when they find the Demon King and escape, Ban says he will play games with Elaine and all the Seven Deadly Sins will meet in the Boar Hat while Meliodas does not cook. There, both notice the presence of some individual observing them.

Meliodas launches to attack his spy with his sword, but all his thrusts are avoided. Ban tries to catch him, but the spy just leaves his hand on the bones and catching him in the back. Ban asks if he is a subordinate of the Demon King, the spy denies it but says that he can take both to the Demon King if they both help him too. When asked what he wants help with, Ban and Meliodas are shocked to see that individual, posing as Wild, looking exactly identical to Hawk.

Wild declares to be a warrior in search of his younger brother. Ban and Meliodas wonder if this brother is Hawk, Wild says that his brother is called Mild, but that having been sent to another world since he was born, he might not remember his real name. Realizing that Hawk could be his brother, Wild breaks into tears of joy.

In the face of the impending sandstorm, Wild takes Ban and Meliodas to his home and offers them wild boar broths. After telling them about how his brother had been kidnapped by the Demon King, he asks both of them to tell him about Hawk. After hearing them, Wild suffers to shock to know how it is, but affirms that he will love him no matter what.

After passing the sandstorm, Band, Wild and Meliodas went to where the Demon King is. After passing the sandstorm, Band, Wild and Meliodas went to the Demon King. On the way, Ban asks how long the Demon King has been in Purgatory, Wild tells him that he has been there long before he was born millions of years ago. Wild also tells them that he faced the Demon King 120,118 times when he was looking for his brother, leading Ban to say that he has an insane tenacity. Ban claims that Hawk crapped his pants to see him. When Meliodas says that he is a good older brother, Ban asks him why he should be. Upon learning that he also has a younger brother, Ban asks him about Zeldris.

Meliodas stops to talk to Ban and Wild about their younger brothers, Zeldris and Estarossa. Ban is surprised to learn that Estarossa is his brother, claiming that they have no resemblance, to which Meliodas says he can not help him in that, leading Ban to ask him to continue his story. After listening to the past of Meliodas and Zeldris, Ban is emotional saying that what they both lived was not useless. When Wild asks about Estarossa, Ban reproaches him. There, Meliodas begins to feel strange about his memories of Estarossa. Suddenly, a voice interrupts them, claiming that he does not remember anything about Estarossa either. This is revealed to be the Demon King.

Ban is surprised to see the huge size of the Demon King, to which Wild says he has grown steadily consuming the life of the Purgatory. After Wild failed to attack him, the Demon King unleashes a blow on all three. Ban manages to evade and catch Meliodas half fallen, surprised of the incredible power of the Demon King. Ban uses his Physical Hunt on him, but to his surprise, his own energy is being absorbed instead. Upon falling with his exhausted strength, Ban is stopped by Meliodas, after the Demon King threw lightning bolts all over the place. Ban wonders what kind of magical power Demon King possesses, which was able to render useless his Snatch and Meliodas' Full Counter, as well as Wild's attacks. Melidoas reveals the power of his father, also called the "Demon King", as "The Ruler".

While sixty years pass in the Purgatory, the trio still battles the Demon King, being defetead every single time they charge at him. After their defeat number 6,093, the three stop to eat. Meliodas begins to think that maybe Elizabeth will not die if he does not return, but Ban convinces him that they should not surrender until they escape and can eliminate the curse of Elizabeth and revive Elaine

Ban and the others return to launch themselves against the Demon King, only so that the same succession of events that lead to be easily defeated by The Ruler is repeated. When they were thrown away, Ban discovers that his powers could also "heal", as Wild's wounds have been "healed" by him by "giving" some of his own life, a fact that develops after the sixty years of his power being absorbed by the Demon King. With this, they also discovered how to get around with Demon King's power, and they charge at him once again.

Ban, instead of using his Snatch to try to steal the strength of the Demon King, uses it to give him his own power instead. This surprisingly ends up weakening the Demon King. Meliodas reveals that The Ruler actually reverses the effects of enemy abilities, turning damage and debilitation into power and healing.

Ban uses his infinite life to keep weakening the Demon King to allow Meliodas and Wild to reach the exit of the Purgatory, However, the Demon King manages to revert the effect by switching off his power. Meliodas then tries to battle the Demon King himself, as the gate to the real world is revealed. Ban refuses to go, saying that he can not leave the Captain behind but Wild decides to use Wild Full Throtle, ultimately leading to his death, as this technique is considered by him his "Trump card", consuming all his life force to increase his power. With this technique, he was able to hold off the Demon King, giving Ban and Meliodas a chance to escape.

As they fall down the exit to the real world, Ban and Melidoas lament that in the end Wild and Hawk can not meet, Ban wonders if they should tell Hawk about Wild's song. However, the Demon King manages to grab Meliodas from Purgatory to prevent him from escaping. Ban tells Meliodas to return to help him, but Melidoas assures him that he will escape by his own means and that he must get ahead to help everyone. Ban tells him that he trusts that he will follow him, while following the path to the real world.

Ban emerges in the real world through Hawk, right where this was with Diane, King and Elizabeth after their battle againts Mael. In his thoughts, Ban tells Meliodas and Elaine that he has returned.
