Demon King/Plot

Defensive Battle for Liones arc
After Meliodas' fight with the Ten Commandments, the Demon King greets him in Purgatory.



He admits to having been keeping an eye on the captain of the Seven Deadly Sins throughout and muses that even Meliodas was unable to do anything other than wait for death when caught by the Commandments of Piety and Love. When Meliodas counter mocks him by saying that he is now free from the Commandments' bindings thanks to his curse, the Demon King is unfazed and agrees while also revealing that he can feel Meliodas' quivering and expresses anger towards the certain woman who had changed Meliodas 3,000 years ago into the shadow of his former self he is now. He then informs his son that despite being greatly weakened, the curse he cast on the Dragon's Sin of Wrath would allow him to feed on his emotions every time he dies, allowing the Demon King to regain his lost power and at the same time reverting his traitorous son back to the state he was three thousand years ago.

Prelude to the New Holy War arc


After Meliodas’s fight with Escanor, the Demon King senses that his son has started to return to his former self, much to his delight. He contacts his youngest son and representative, Zeldris, and shows no interest when Zeldris expresses he will find the one who killed the demons guarding Camelot. Instead, telling Zeldris that while his seal is not yet broken, Meliodas will now replace him as the rightful heir to the throne of the demon king. Despite Zeldris obvious shock and visibly anger, the Demon King sarcastically rebukes his calling Meliodas a traitor, as Meliodas shall now be welcomed as the new Demon King. Although Zeldris tries to reason with his father, the Demon King sternly silences Zeldris by saying he will not hear any objection to Meliodas's rule and crown him as the new demon king and kill the Seven Deadly Sins before they become a further threat. Zeldris reluctantly accepts and the Demon King reminds him that he observes everything from the Purgatory.

New Holy War arc


In the Purgatory, the Demon King appears threateningly looming over the emotions of Meliodas, Ban, and Wild when Meliodas said that he has no memory of Estarossa. Revealing that he too cannot remember anything about his middle son, the Demon King disgustingly said that the effeminate nature of Meliodas's emotions made him sick and his son has no need of the existence of these.

Wondering on how Meliodas's emotions returned to his original form and why he and Ban got there, the Demon King quickly realizes that Wild guided them and deduced that they have learned on the existence of the portal to the living world. Wild bravely charges at him, saying that he will finally force through the Demon King alongside Ban and Meliodas, but the King effortlessly flicked him away with a single finger. The Demon King then began pressuring Meliodas and Ban with quick slashes, declaring that they will never return to the living world and soon cutting off Ban's arm.



After commenting on the Demon King's massive power, Ban attempts to steal the King's power, but the Demon King's Magic Power repels the assault back to Ban, instead of absorbing Ban's power for himself. He continues overwhelming Ban and Meliodas with his sword while laughing mockingly at Ban and Meliodas for their efforts. The Demon King is soon attacked by Wild but remaining completely unfazed; he merely grabbed and almost crushed him with his fingers before throwing him away while admonishing them for not giving up, confidently saying that as long as he guards the door, it is impossible for anyone to pass through the door. Not fazed by Meliodas's comments that he is not the one who decides that, the Demon King corrects his son that he is the one who decides everything in Purgatory and unleashes several strikes of thunder at Meliodas, but Meliodas Full Counters it. Remaining unfazed by it, having absorbed it with his magic power, the Demon King gives them the choice of continuing to fight and be killed or to flee, but the king suddenly asks on what Meliodas knows on Estarossa, as he cannot remember him while he remembers all that happened as well as every member of the Demon Clan. When Meliodas tells him that while Estarossa was his son, he was born without the power of darkness and a weak-hearted coward who could not even kill a single insect, the Demon King completes that part by saying that he took pity on him and gave him a Commandment, shocking Meliodas. The Demon King then realizes that Gowther is behind this as he was the only Commandment who betrayed the King and the only one who can do so.



For 60 years, the Demon King effortlessly continues to overpower his son's emotions, Ban, and Wild, all the while looking unperturbed as he blows them far away. When they come to rechallenge him, the Demon King admits to being impressed by their bravery and tenacity but rebuffs them for not having learned anything, as his physical constitution makes any attempt of Wild to harm him utterly futile. Additionally his ability The Ruler can easily counter Ban's attempts to steal his powers instead make him even more mighty and the Full Counter possessed by Meliodas also does not affect him due to him just absorbing the redirected magical energy. Before knocking out Meliodas and blowing away Ban and Wild too, the Demon King notes that Meliodas's Full Counter is just a weak copy of Chandler's magic power. Only with his original magic power can he even hope to fight against him but mocks him for being too afraid, hence making it impossible for him to use it.



Later on, when Ban uses his Snatch again, the Demon King is exasperated by how Ban has not learned that any attempt to steal his power is futile. However, he finds that Ban has learned to "give" instead and as his magic power is inversion rather than absorption, the Demon King is weakened. As Meliodas points out the truth of the King's incredulous magic power, he is unconcerned, instead actually feeling it would alleviate his boredom, but insists that he will never let Meliodas's emotions leave Purgatory.

As he attempts to attack them again, the damage inflicted by Ban being only mediocre and not any hampering, Ban uses the full extent of his immortal life-force to stop the King to buy time. However, the King reverses the inversion aspect of The Ruler and instantly recovers. He easily grabs Ban in his hand and slowly crushes him while being intrigued at how Ban can offer slight defiance. Unfazed when Meliodas saves Ban, apparently activating the full extent of his powers, the Demon King is not at all willing to let Ban and Wild pass the gate even without Meliodas's emotions and attacks, but Meliodas surprisingly deflects it.



Infuriated, the Demon King rages on how Meliodas defied his father, but Meliodas coldly told the King he is no longer his father but is not able to understand why he keeps referring to Meliodas's emotions as a failure. The two trade blows, with the Demon King parrying every blow with his massive sword with ease while telling his son it is because of Meliodas's emotions destroying his plans of passing on the mantle of the King of Demons into his son, which Meliodas scoffs at, telling his father he is more of a destroyer than Meliodas ever was. Soon, the King gets the upper hand, forcing back Meliodas with a slash despite his attempts to parry before submitting him with another sword blow. He muses on how while Meliodas is the only worthy being of his throne, his emotions are unnecessary and prepares to kill him. However, he is suddenly slightly injured by Wild, shocking him as he looks at the beast. Wild holds the Demon King back with all of his life force and power while pushing Meliodas and Ban to the gate. The King quickly regains the upper hand and forces Wild back, killing him finally, but the attack on the King has bought enough time, and his son's emotions and Ban successfully escapes.

The Demon King manages to grab Meliodas towards the exit with his arm, stating he will never allow him to return to the real world. However, the Demon King's arm is severed, surprising the Demon King that his son has used his original magic power with the power of harming him. The Demon King says that he cannot go back because he will ruin all his plans, contenting Meliodas when he first saw his face of anguish.

When in the living word Meliodas finally absorbs all the ten Commandments and emerges with a new aged and stronger body, it is revealed that absorbing all of them, actually allows the Demon King to take possession of that body. After recognizing Elizabeth and the Seven Deadly Sins and regret that Zeldris remains attached to Gelda as Meliodas to Elizabeth, everyone understands that they are not talking to Meliodas but to the Demon King. Zeldris demands his father explain why he is in the body of his brother after having told him to crown him as his successor, leading the Demon King to reveal that he never intended to give the throne to his treacherous son and that what he really wanted was a young and strong body.

After being confronted by Elizabeth and the Sins who demand that he leave the body of Meliodas, Hawk asks how he does that to his own son, to which the Demon King says it is so as not to waste his true potential. The Demon King says that he will free Elizabeth from his curse, but only to be able to kill her brutally, wondering what face Meliodas will put on him when he sees his corpse and if he will become depressed and want to join her in the afterlife or perhaps relieved of not being held back for her. After Gowther saves Elizabeth from his murderous attack, King, Diane and Mael attack him with physical attacks knowing that the magic does not work against him, but the Demon King easily defends himself from all their attacks and incapacitates everyone with a simple movement. He states that the resistance is useless and that Elizabeth must let him end her miserable life for good. Hawk begins to provoke him and warns him to not kill Elizabeth. The Demon King destroys Hawk's little Perfect Cube with his claw, heavily wounding him, saying that looking at it was very irritating, remembering back to how Wild confounded him back in Purgatory and that he will send the piglet to where his brother is. However, Hawk is snatched from his clutch by Ban, who states to take the Demon King out of Meliodas' body.

The Demon King sarcastically asks him how he intends to get him out, which Ban says he will simply do. Calling him a foolish child, the Demon King says he has the power of a god and releases a toxic and caustic storm over the entire area. Ban, however, supports it without problems, stating that compared to what he experience in the Purgatory that is just a nice breeze.

The Demon King tries to attack him with his claws, but Ban uses his speed to evade and punch him in the face that the Demon King manages to block, having to stop his storm in the process. The two then enter a physical contest, after receiving a kneeling of Ban, the Demon King responds with several quick aces that Ban manages to evade and respond with many short and quick blows. The Demon King however manages to strike him in the stomach and back, claiming that he was a fool believing he could do something against him by his own. However, the blows begin to affect the Demon King, to which Ban says he is not alone.

Inside the body, the emotions of Meliodas confront the Demon King. This affirms that even if he managed to return, he would not let him do what he wants, since bringing death and fear is his duty and his own existence. However, Meliodas evades his sword and elbows him to knock him down, claiming that this is also his sin.

After regret not having destroyed them in the Purgatory, the Demon King continues his fight against Meliodas and Ban. In both scenarios, their attacks are completely bypassed. Ban responds with a strong kick to the head, while Meliodas confronts him with a sword of darkness. The Demon King is surprised that Meliodas repels his attacks, to which Meliodas tells him to leave at once because his true body in Purgatory feels lonely. The Demon King reminds him that now that his body awoke the power of the Demon King, he could no longer be in that world for more than a day, but Meliodas affirms that it is okay as long as he can break the curse of Elizabeth and say goodbye to the Seven Deadly Sins.

In the living world, Ban manages to strike hard at the Demon King, while in the spiritual world, Meliodas cuts off his chest and one of his horns. There, the Demon King tells Meliodas that there is no need to go and look for Elizabeth, because she is already dead and that he could never have her in his arms again. Meliodas calls him a liar, but even so Meliodas succumbs to the sadness of this possibility and there the Demon King sees the opportunity to attack him. This gives the Demon King the opportunity in the living world to regain strength after having been stamped against the ground by Ban, holding him by the neck with his claws and piercing the abdomen with his fingers. The Sins try to talk to Meliodas to help Ban, but the Demon King tells them that their voices never reach him in the spiritual world.

There, the Demon King tells a badly beaten Meliodas that embracing the despair in that spiritual world is accepting death. The Demon King tells him to sleep and leave everything to his father because there is no one out there waiting for him. However, Meliodas is backed by Elizabeth and the Sins, who entered the spiritual world thanks to Gowther's magic.

The Demon King is infuriated by their presence there and attacks with intention of eliminating them. However, Meliodas is able to repel his attack and knock him down with several holes in the chest. As the Demon King ask how is he able to have that power, Meliodas stats that he has lost any chance of defeating him since his friends's existence and emotions have given him strenght.

In the real world, The Demon King suffers the damage of Melodias's attack that forces him to release Ban. There, he decides to cut off his son's power source by murdering Elizabeth and the Sins whose physical bodies were immobile under the magic of Gowther. Mael and Ludociel jump to protect them, but the Demon King says that some Archangels like them have no right to challenge a god.

The Demon King sends his ornaments to the sky which are transformed into a great face called Tansoku no Kenjin. When Ban uses his Snatch to send the face to the ground, the Demon King sends him flying with an elbow, ordering everyone to stay out of their family affair with their son. The Tansoku no Kenjin releases a powerful attack from its mouth, which devastates much of Camelot. Ludociel manages to use his Sanctuary to protect himself along with Mael, Hendrickson, Elizabeth and the Sins, but the Demon King says that nothing will be left of him in five seconds. Ban resists Tansoku no Kenjin's attack and decides to stop the Demon King before he kills the others, but the Demon King manages to keep on par with him in a fight.

However, someone intervenes by stopping the Tansoku no Kenjin by piercing it with his sword, leaving everyone surprised when it is revealed to be Zeldris.

The Demon King asks Zeldris to tell him the reason for his actions. Zeldris tells him that he wants him out of his pending affairs with Meliodas, but before that he has something to ask him: if he knew about his relationship with Gelda when he ordered him to execute the Vampire Clan. The Demon King says the he is a fool for not understand that he did it to save him from himself and his own weakness. He reveals that the Commandment that he bestow to him have revealed everything about his secret love with Gelda, the sealing of the vampires and the hope to reach the throne of the Demon King to create an underworld in which everyone could live in peace, something that the Demon King calls pathetic.

The Demon King states that Zeldris' loyalty was what saves him all that time, but he will no longer turn a blind eye. He then creates Setsuna no Inja, a spell creature, to fight Zeldris, while the Demon King continues his fight with Ban.

While in the spiritual world, the Demon King spirit is being overpowered by Meliodas, who uses several concentrated darkness spheres to penetrate his armor and flesh. With his sword destroyed, the Demon King falls bloodied from Meliodas attack, who contents to end the fight with his next attack.

As Zeldris defeats the Setsuna no Inja, the Demon King shoots a energy energy bolt that cut open Zeldris' chest. As Mael points that magic is not supposed to affect Zeldris, the Demon King reminds Zeldris than that is a power that himself gives to his son. Ban take the chance to recover and hits the Demon King with a kick.

Ban strikes the Demon King with fury claiming that Zeldris is his own flesh and blood. The Demon King hits him back stating that he does not need weaklings in his bloodline. Ban gives another strong blow leaving him in bad condition. At the same time, the Demon King is riddled by Meliodas's Trillion Dark. At the doors of his demise, the Demon King begins to fly across the battlefield in a state of madness, in a desperate attempt to take Meliodas to the death with him.

Ban manages to intercept and stop his death throes, and then send him flying with a kick. King, Elizabeth and Merlin then combine their techniques in their Combined Technique: Triple Prison leaving the Demon King trapped. This however manages to break free in a berserk state. There, Diane surprises him with her Diamond Tower, giving Ban the clean guy to give the Demon King the final blow. With a strong fist that sends the Demon King to break the diamond, this is finally defeated and erased from the body of Meliodas.

Demon King arc
After the Demon King's defeat, the ten Commandments are expelled from the body of Meliodas and are left to the disband. However, these are found by Cusack while they were disappearing. Thus, while the Sins were distracted by their victory, Cusack takes the Commandments as well as an unconscious Zeldris to a cave. There, Cusack performs the ritual for the Commandments to enter Zeldris' body, without listening to Zeldris's prayer so he does not. After two days of being a cocoon, the Demon King emerges now inside the body of Zeldris. After assassinating Cusack affirming that he has already fulfilled his purpose, the Demon King indirectly tells Meliodas that he is still alive.

While wandering randomly through Britannia, the Demon King runs into a couple of human farmers who confuse him with a child. Seeing that his current appearance does not match that of a king, he transforms his outfit completely to one that resembles his true form, which frightens the farmers. Searching to prove his magical power, the Demon King levitates and compresses the house and part of the hill. He is impressed with the power he has in Zeldris' body, claiming that he was concerned that he was not as powerful as Meliodas, and that once he has it fully controlled, he will recover all his power as a Demon King. He also tells a dominated Zeldris that he must be a good boy and does not rebel like his foolish older brother.

The Demon King soon realizes that as soon as the Seven Deadly Sins realize that Elizabeth's curse was restored, they will eventually find him without having complete control of his new vessel. He thinks about sending some of his demon minions to entertain them, but he soon realizes that not even the Ten Commandments could fight against the Sins as they are now. There, the Demon King notices a strange magic that should not be in that plane and decides to take advantage of it affirming that whoever invoked it did so at the right moment.

Then, the Demon King reopens the entrance to the Demon Realm that had been opened by Merlin and was about to close, and uses it to invoke an Indura from the Demon Realm.

In order to recover the magic that he lost in his fight with the Sins, the Demon King goes to the magic lake of Salisbury to wait for Meliodas. There, Zeldris awakens within his spiritual world. When he remembers what happened, he repeatedly asks his father to return his body. However, the Demon King creates an illusion of Gelda who affirms that it is the separate spirit of the true Gelda that was killed by Meliodas and the Sins and that Meliodas lied to him when he told him that he had sealed her in order to make Zeldris help him gather the Commandments. Zeldris does not believe him and says he is not real because his father would never allow him to be there. The illusion of Gelda tells him that his father has authorized their relationship and that now both can be together forever without having to hide. Consumed by the desire to be with Gelda, Zeldris stops trying to recover his body and the Demon King takes full control.

When Meliodas and Elizabeth arrive, a tremendous storm of lightning strikes. The Demon King claims that the environment is enraged because it does not need the existence of two Demon Kings. Meliodas replies saying that there should not even be one. Meliodas says that everything they have attacked is due to a useless quarrel between him and the Supreme Deity that continues even 3,000 years later. Meliodas asks if he knows how much blood and tears were spilled or how many lives were lost, the Demon King responds that it is the same as thinking about the swirls and grains of sand on the side of the road. Meliodas states that during his time at his service, He never felt anything during each fight after another, but that Elizabeth and all the friends he made put his world upside down and took him to where he is. Warning him to prepare, Meliodas claims to throw all his feelings in his face. So he launches and exchanges a blow with the Demon King. He mocks that if it is all the power that those feelings have, but the Meliodas immediately hits him a second blow to the face.

After retiring to the sky, the Demon King exclaims that he never expect Meliodas to become so much a failure. He asks him if he really intends to eliminate his brother who in fact if he cares about his father and then erase his own existence. Meliodas denies it by claiming that he will be the only one to disappear and that Zeldris will indeed save him. The Demon King asks what would happen then to what Meliodas claims to kill him right there.

Annoyed the Demon King launches a blast of darkness that does not hit Meliodas, but raises a cloud of steam from the water that gives him the cover to catch Elizabeth and take her hostage. The Demon King boasts of his error in bringing her and that given his desire to protect her at all costs now that her curse is reactive, he only has to use her as a shield until he regains the power of his original being. However, Elizabeth laughs that he is wrong if he thinks that she was only to delay Meliodas, but that she did it to defeat him.

Elizabeth then wraps him in her Ark. The Demon King claims that this pathetic technique will not affect him, but Elizabeth uses Manipulate and Burst and shakes him all over the place and finally producing a big explosion that leaves him wounded. Meliodas warns him that he will know a world of pain if he underestimates Elizabeth just like he did long ago, reminding him of the name they used to give her in the underworld: Bloodstained Ellie.

As Meliodas jumps towards him, the Demon King engages in a sword fight with him, receiving a heavy blow. The Demon King tries to respond, but Meliodas eludes him and sends him flying with a impact from Lostvayne.

The Demon King then uses his magic to create the Gokumonto, but Meliodas uses Lostvayne's Jitsuzō Bunshin and reflects his attack with Full Counter. Elizabeth then joins Meliodas to obliterate the Demon King with their Combined Technique: Kamigui.

As the Demon King curses him, Meliodas comments that he can not invoke his The Ruler power or maybe the vessel is not compatible enough to use it. Meliodas says he has no chance to defeat them so if he does not want to be crushed he must leave Zeldris and return to the Purgatory. The Demon King says that he can feel in the vibrations of the air and the ripples of the water that Meliodas is desperate.

When he tries to get up, Meliodas intercepts him with a nudge. The Demon King throws his darkness, but Meliodas eludes him and gives him an upper. After his next series of blows, the Demon King stops the last one with his arm saying that he feels flimsy. Meliodas throws him sword slashes that the Demon King dodges by calling them sluggish. The Demon King asks him if he is actually trying to save his brother to what Meliodas kicks him down.

Knocked down with a wound on his forehead, the Demon King confirms his earlier claim by noting that Meliodas is not only not using the power he gained that rivals his own, but that he is not even using his demonic power; so the Demon King calls him a fool.

As the darkness comes out his body, the Demon King says that Meliodas is so concerned about his brother that he is not using his full power and in fact, his original power as Demon King is recovering and inceasing thanks to the magic lake. As the Demon King stands with a big and stronger body, he declares that the only possible conclusion is his victory. Meliodas throws himself crying out to Zeldris not to let him control him, but the Demon King resists his blow without any problem claiming that Zeldris' consciousness is lost in the illusion of his greatest desire and will soon disappear. The Demon King assails Meliodas with several punches ordering him to disappear as well, but Meliodas activates his demon mark and wounds him with a blow and several cuts of his sword.

Meliodas swallows him in a swirl of Hellblaze, but the Demon King can only rejoice that his power grows more and more.

The Demon King emerges from the flames with a new even powerful body. He exclaims that feels so relived and thanks Zeldris for his sacrifice that grant him his original power back along with the body and power from his youth. Meliodas still calls for Zeldris, but the Demon King says that the brother he is trying to save is already gone. Meliodas refuses to accept it and claims the he will save him, but the Demon King denies that he can do that on his own. During a sword clash, the Demon King ask if he rather is expecting help from the Seven Deadly Sins. After a big slash that cut open the lake, Meliodas says that would be asking too much. Meliodas returns with a slash and kick on his own affirming that he already owes them too much and can't allow them to put anything on the line for him. The Demon King asks if he really wonders to defeat him on his own before giving another slash. Meliodas says that he promised Zeldris to make him see Gelda again no matter what, but the Demon King starts to overpower him. Elizabeth says that he must retreat for now and return with a plan, but Meliodas refuses to abandon Zeldris for a third time and says that anyone will save him if he does not.

Meliodas then uses Kami Chigiri, but the Demon King absorbs all the flames with his The Ruler power. He says that not expect nothing less from the body that he choose as vessel and how it is a great opportunity to test his power.

Suddenly, the Demon King notices that something is approaching at high speed. This result to be the heads of the Indura that the Sins have launched towards him. The five Sins have arrived to help Meliodas.

The Demon King stands claiming to be death, fear and a god. Taking the heads of the Indura, he uses them to attack the Sins claiming that their remaining pieces of life will be hatreds of hatred and rage that will crush their enemies. Merlin quickly teleports the heads behind the Demon King, resulting in this one being hitted by the attack. However, the Demon King receives no damage thanks to The Ruler, which impress Merlin.

Hearing Ban about the inversion nature of the Demon King's power, Elizabeth uses Invigorate hoping to that its healing turns into damage. The Demon King then switch off his power, but Merlin launch a magic blast hidden behind Elizabeth's technique, catching the Demon King in a fiery explosion.

As the Demon King is taking back, Merlin tell Gowther to take Meliodas inside the Demon King's soul and detach him from Zeldris while they distract him. Not wanting to allow it, the Demon King launch several dark slashes that Meliodas, Ban and King are forced to intercept. The Demon King then attacks the others. Merlin teleports to avoid him while Ban takes Diane, Gowther and Elizabeth.

King uses True Pollen Garden to protect everyone and give Gowther a chance to use his power, but the Demon King quickly break his defenses forcing Ban, King and Meliodas to keep fighting. Merlin states that fighting the Demon King and protect Gowther and Meliodas' bodies at same time is too difficult for them to do it.

Suddenly, Escanor, having ragined his magic power, stops a lunge of the Demon King with his arm. As this one recites a poem about how he has decided to offer his life for his companions, The Demon King ask who is he, since he can't recognize him. Meliodas exclaims that he stops because what will happen if he stays that way. Distracted by this, Escanor receives a blow from the Demon King who then tries to attack him with his sword, but Escanor goes through it with Divine Spear Escanor, stating that a blow as light as that is not even close to tacking him down.

The Demon King responds with Kami Chigi, but Escanor overcomes him with Divine Sword Escanor, saying that killing a god is the only way the fire inside him will go out. Diane questions that claim, but Escanor only tells Meliodas to save his brother while he manages the situation, since he will not be able to continue in that world if he accidentally kills the Demon King. Escanor then begins to cough and languish, just when a Demon King furious at his words attacks him. However, Ban interfere sending him to fly with a kick and then King rains his True Increase. Having finally the opportunity, Gowther shoots an arrow from Herrit that manages to hit the Demon King, successfully entering his soul along Meliodas

As Meliodas and Gowther find Zeldris trapped by a false Gelda, Escanor continues to fight with the Demon King alongside Ban and King, managing to take the upper hand.

The fake Gelda tells Zeldris not to listen to Meliodas, that he has killed her, that he will betray him again and that she is the only one who really loves him. Zeldris tells her that he already knew, that she is not the true Gelda but that he really wanted it to be. She insists that she is the only one who loves him, to which Zeldris says that shows him that she is fake, because the true Gelda would never say something like that.

While the fake Gelda disappears, a fog covers the place while the Demon King's voice calls Zeldris fool for following the same path as his brother. The Demon King then creates many illusions of Zeldris to confuse Meliodas, since if he does not distinguish the true one, he will be expelled from the spiritual world like Gowther by preventing him from destroying an illusion.

Meanwhile on the outside world, while the Sins were distracting him from their attacks, the real Gelda surprises the Demon King by biting him in the back. However, as the Demon King recognizes Gelda as the woman who "seduced" Zeldris, he rips off her head and throws it along with her body in the water.

However, Gelda is able to survive thanks to her vampire regenerating abilities, while adding that Zeldris' blood also strengthened her powers. The Demon King states the she is useless there, but she reveals that the bite she gave to the Demon King was not meant for an attack, but a way of connecting her blood to Zeldris' so she could enter the spirit world of both the Demon King and Zeldris. Meanwhile in the spirit world, Meliodas is having trouble picking the real Zeldris from all the fake ones trapped on extended strings. Gelda arrives in the spirit world and claims she is going to find the real Zeldris herself.

When Gelda manages to identify the real Zeldris, the Demon King controls the fakes to attack her before she releases him. However, Meliodas shields her and with the use of her Kami Chigiri, destroys the false ones and frees Zeldris.

After Meliodas dissapears from the spirit world, the Demon King finally appears in front of Zeldris and Gelda saying that his body already belongs to him and that he will never see his brother again. Zeldris replies saying the he must just take him down.

While in the real world he continues to fight with King, Ban and Escanor, the Demon King manages to engulf them in a fiery explosion that leaves them badly injured. When Elizabeth heals them, he attacks Ban while distracted, but Escanor tackles him and then King hits him with Chastiefol while Ban with Courchouse. However, the Demon King manages to take no damage thanks to the unlimited magic provided by the lake.

When Elizabeth's curse was about to kill her with a lightning from the sky, Meliodas returns from the spirit world in time of Full Countering the lightning to the Demon King.

When Diane starts her Drole's Dance, the Demon King recognizes it as the annoying technique that allows the giants to increase their fighting power. He then attacks Diane with his darkness before she completes the dance, but is intercepted by King.

Diane then unleashes her Mother Creation technique, causing an earthquake that destroys all the land near the lake and lifting an infinity of debris. Diane throws some of them at the Demon King, but he destroys them making fun of an insignificant giant girl dares to challenge him. However, Diane manages to wrap it with so much debris that the Demon King is lifted from the lake.

The Demon King tries to regain his posture, but Diane continues to throw debris, calling on his friends Sins, Elizabeth, Hawk and especially King who always protected her, were always with her. The Demon King states that there is no reason for her to defeat him, but Meliodas and Elizabeth claim he is wrong that what moves Diane.

King then decides to ask Diane that once they defeat the Demon King, they get married. Diane blushes and screaming that of course she will, she throws all the rubble that manages to take the Demon King of Lake Salitsbury, thus cutting off his source of magic.

After noticing that he is in a place he does not recognize, Meliodas says that it is his last resting place since they Sins are about to launch their mission to defeat him now that without the lake he has lost his ability to recover magic. Escanor points out that he has even more bad news for him: it's high noon.

When Escanor becomes The One, the Demon King remembers seeing from Purgatory how he used that form to defeat Meliodas and Zeldris in a single minute, and then encourages him to attack him to take a taste of that power. Escanor simply calls him the king of gods, which confuses the Demon King.

The two then exchange a pair of powerful blows and then cross the same blows releasing a large shock wave. The Demon King then deals some blows that manage to drag Escanor away, then asking him how he feels the power that surpasses that of his unsightly children. Escanor quickly surprises him by saying that he doesn't feel a scratch, proceeding to punch him on his knees.

The Demon King continues to hit Escanor saying that his ignorant pride left him speechless and that is why he will silence him, but Escanor manages to give him a headbutt to which the Demon King responds with an upward blow and Escanor with an elbow.

The Demon King recognizes Escanor for having resisted, surprising himself of the existence of someone in the world capable of facing him in such a way, but having already spent a minute, the victory belongs to him. The Demon King proceeds to bury a blow to Escanor in the womb, but surprisingly, Escanor's power does not diminish despite having spent his time as The One.

Turning his own life force into magical power, Escanor manages to maintain his The One form he calls the Ultimate. Maintaining his fierce battle with the Demon King, Escanor manages to engulf him in his power before suffering a wound in the stomach. The Demon King then breaks free and attacks Escanor with his darkness, but Meliodas vanishes his attack with Counter Vanish. Ban and King then attack him with Vanishing Kill and Fight Fire with Fire, getting hurt and contain the Demon King.

This one, however, is released creating a great monster of darkness. However, the monster is quickly defeated by a combined attack of all Sins.

Meanwhile, in the spirit world, the Demon King shows Zeldris an illusion about the confrontation he had with Meliodas when he decided to leave the Demon Clan, in it Meliodas states that he will not hesitate to kill him when he gives up the moment and that he never considered him his little brother to begin with. The Demon King states that this is the true nature of the brother he intends to trust and that he only intends to deceive him. Zeldris, however, is not fooled and destroys the illusion with a slash of his sword, damaging the Demon King as well. Zeldris reproaches him that no matter how many lies he throws at him, he knows what really is in Meliodas' heart even though he once convinced himself that he had betrayed him.

The Demon King exclaims that he does not understand what a father feels for having to kill his beloved son with his own hands, just before giving a great blow. Zeldris jumps out of his attack with Gelda, stating that he never felt any love on his part and that if he is going to resort to the pity to get his point across, he has really fallen. The Demon King gives another sword strike telling him not to be arrogant and that if he thinks that if someone like him can ever bested him. Zeldris jumps giving him a strong blow of his sword in the head, saying that although he is not as strong as his father or Meliodas, being in the spirit world has full fighting opportunity given that like Meliodas, he also has someone to risk his life for.

The two engage in a sword fight where the Demon King says he will never fall before a weakling that is under a woman's thumb. As Zeldris is pushed back, he tells his father that he will never understand the strength that loving and being loved by someone can give you. Zeldris tells his father that in those moments his pride is destroyed and his heart is weakened, because he was already defeated by the emotions of Meliodas he considered weak and is now being defeated again. The Demon King asks him if he thinks he could be defeated twice and says he can't know what's going on outside. Zeldris says he knows it because he trusts his older brother.

Zeldris then unleashes his Ominous Nebula, and the Demon King asks him if he is really going to challenge his father like that. Zeldris only says that he already told him that he was going to defeat him, before seriously injuring him with his power.

At same time, The Demon King is taken to the limit by the Seven Deadly Sins. There, Gelda returns from the spirit world watching the Commandments begin to leave Zeldris's body.

Although the Commandments detach from Zeldris's body, the Demon King's conscience refuses to let his vessel go and tries to retrieve it. However, Ban snatch Zeldris away before the Commandments can possess him again.

Enraged, the Demon King rises and saying that they observe him, the Commandments separate and disperse in the surrounding area beginning to take over every living being, rock and hill. Thus, the Demon King stands with a new, gigantic and monstrous vessel created from the same land of Britannia.

The Demon King says he can see the faces of people in Britannia crumpled in fear all thanks to the sinful foolies they have commited. He then shouts to be resigned to their deaths because there is no greater crime than opposing the Demon King. However, the Seven Deadly Sins makes a completely confident face. The Demon King demands to know why they have that expression on their faces, to which each Sin and also Zeldris remarks that they are not afraid of him and that he has no chance of winning.

As the Sins launch to the attack, the Demon King uses Death Zero to immobilize them with gravity pressure. He tells them to be slowly crushed out from existence as insects that have no chance against a mountain. Escanor and Ban tries to fight back, but his attacks are ineffective as the Demon King affirms that gods can't fell pain or fear. Ban says than that makes him look pretty dead to him.

The Demon King continues to make pressure in his technique, claming that he will end the Holy War having taking the life forms whitin that land as vessel. However, Merlin uses Limit Breaker, rising hers and her companions's magic power to the absolute top, breaking the Death Zero in the process. The Demon King react angry against Merlin as she fools him in the past, to which Merlin says that he shouldn't have gotten in her way.

The Sins then launch their strongest techniques that Melin combines in a single powerful attack. The Demon King believes that his power The Ruler will protect him, but Merlin reveals that the Killer Switch that Gowther have used was not an attack, but a spell that negates his power. The Demon King tries to destroy the combined attack with Death Zero, but the attack proves to be too powerful as Gowther remarks that he is not able to overcome the resolve within their hearts.

The Demon King ask Meliodas and Zeldris if they really are content with killing their own father. As Meliodas send a clone to Full Counter the technique away, the Demon King tries to kill him claming that his stupidity has helped he live for too long, revealing that it was not the real Meliodas. The real one revelas that he was actually giving him a last chance, but that he can now eliminate him without hestiation. Meliodas creates various clones that repeteadly uses Full Counter in the combined attack sending it back at the Demon King, multiplying its power each time. The Demon King cries that if the attack hits him again Britannia will be damaged. However, Meliodas sends the attack to the Demon King, defeating him once and for all.

In a final meeting in the spirit world, the Demon King says to Meliodas that he will regret what he done and that he must be aware of what he incited by ending the cycle of light and darkness, to which Meliodas say that of course he knew that. There, the Demon King vanishes.
