After Zeldris suggests recuperation at Edinburgh Hill to recover their severely drained magical powers, Estarossa took flight and left Zhuhur Valley, following his comrades while leaving behind a terrified Hendrickson. Arriving at Edinburgh Hill, Estarossa and the rest of the commandments find a deformed castle. Estarossa decides to relax on the ruined castle. He appears before Elizabeth Liones, in her dream, where she mistook him for Meliodas in the latter's wanted poster. Curiously he is wearing the same armor Meliodas wore 10 years ago.

Istar arc
After getting bored of waiting, Estarossa and the others decided on eating human soul to slowly return their magic back by sending a Red Demon and a Gray Demon until the demons were stopped by three Holy Knights and Hendrickson. Estarossa was confronted by Meliodas when the latter arrived to give them a warning. He then proceeded to watch Galand fight Meliodas, where the former was beaten in under 10 seconds.

After Meliodas' warning, Zeldris suggests that the Ten Commandments split up and move across the land to regain their magic faster while calming Galand down after his loss against Meliodas. However, Zeldris remained behind and Estarossa refused to move as he wanted to relax after being sealed for so long. Zeldris decided to look around, leaving his brother alone to relax. A bird lands on Estarossa arm and begins chirping until it suddenly grows into a mutated beast and subsequently explodes.

Great Fight Festival arc
He, along with the other Commandments, arrive to aid Drole and Gloxinia, who are facing off against Meliodas. For most of the battle, he stays on the sidelines, merely observing with a smile but, when Meliodas attempts to finish them all off in one go with his move, Revenge Counter, Estarossa finally steps in, and effortlessly halts the attack by placing his hand on Meliodas' blade. He tells the barely conscious Meliodas he truly didn't want it to come to this, and asks if he understands as he begins to crush his chest underneath his boot. He explains it's because he loves Meliodas. As he listens to Meliodas screaming, he begins to reminisce and when Meliodas' comrades are mentioned, he becomes angrier, beginning to choke Meliodas as he sarcastically asks when he plans on betraying them. He laments over how great Meliodas used to be before his unexpected betrayal, before deciding to let Melascula finish him off.

However, before Melascula can eat Meliodas' soul, she is summarily killed by Ban of the Seven Deadly Sins. Estarossa believes that Melascula deserved to die for daring to try to eat his brother's soul, and even thanks the human before admitting that he was about to kill her anyway. He then proceeds to destroy each of Meliodas' seven hearts, as Ban tries to stop him in vain. He cries as he kills Meliodas, and obliterates Ban for being too noisy. When the deed is done, Estarossa declares Britannia at the Demon Clan's mercy, and the Ten Commandments set out again, to solidify their conquest.

Defensive Battle for Liones arc
After one month of uncontested reign, Estarossa, Grayroad, Fraudrin and Zeldris are confronted by several Holy Knights and Ban, while trying to conquer Liones Castle. Revealing the effect of his Commandment and rendering all his opponents powerless, he is surprised when Escanor suddenly appears unaffected. Escanor states it because the only thing he feels towards those weaker than him is pity, and Estarossa comments on the arrogance of that remark, as they stare each other down.

When Estarossa realizes that Escanor must have been the one to defeat Galand Escanor tells him not to hate him, as it would ruin the fight if he was powerless. As they share a good-natured laugh over Escanor's concern, Estarossa suddenly uppercuts him and then punches him into the ground, then kicks him back to the surface. He moves in for another attack put sees the visage of the Sun and suddenly blocks one of Escanor's attacks. Though at first, he seems fine, he momentarily becomes dizzy and falls to his knees. Estarossa, becomes excited at the prospect of a real fight, but Escanor calls his statement presumptuous and brings Rhitta down for an attack, only for it to rebound back to him. Estarossa explains his power, Full Counter, and the two exchange names, in preparation to kill one another. Escanor then decides to fight seriously as well and materializes a miniature sun.

After confirming the location of a nearby lake with Ban, Escanor bunts Estarossa away, crashes him into the lake, and vaporizes it in an instant. Estarossa survives, thanks to his darkness, and quickly heals his wounds. When they both decide to end things quickly, Estarossa wraps Escanor's Cruel Sun in the darkness of his Blackout technique and charges, they clash, and again Escanor's attack is rebounded at him. Estarossa states that his magic is superior because he can block out Escanor's sun, and Full Counter makes all physical attacks useless, assumes that he has won.

But then suddenly Escanor slashes his chest with an attack he could not see, and his sun dispels the darkness. Estarossa doesn't understand why Escanor's power is increasing, and Escanor tells him the only one who makes decision about his power, is him. He then commands Estarossa to die and unleashes a furious attack. Zeldris attempts to aid his brother, but both of them are sent flying off into the distance.

Prelude to the New Holy War arc
When Zeldris was trying to contact the other Commandments, it is revealed that Estarossa survived the battle with Escanor, although having fallen into a coma for four days. Weakened, he manages to wake up, when he overhears Zeldris' and Cusack's conversation about the Demon King's decisions about Meliodas. He asks if Meliodas is still alive but is quickly interrupted by his brother who advises him to fully recover.

After this, Estarossa would wake up due to a dream in which Elizabeth would appear asking him if he had returned to fight with his older brother after this. Estarossa would react very surprised, which would awaken him from his dream to end his recovery. After this, there is a woman named Peronia, who tells him that she has been taking care of him since he was in a coma but Estarossa rebuffs it, saying he knew she was experimenting with him. After this, he would dress to rejoin Meliodas and Zeldris, something that had not occurred in several years, but that would notice the presence of Elizabeth, this surprises him despite the fact that both claim not to know each other. The brothers' debate who would be the new Demon King, something that does not interest at all to Estarossa. However, Estarossa says that he wants Elizabeth in exchange for not fighting for the throne, but Meliodas says that he will be the Demon King and that he will not surrender Elizabeth to Estarossa, for which Estarossa and Zeldris launch against Meliodas, with Estarossa saying that Meliodas is a coward and has no right to covet. However, Meliodas effortlessly overpowers them, pinning them to the ground with darkness so powerfully that even Zeldris with the power of his father could move a millimeter, however, Estarossa could briefly resist, expressing curiousity on how much Meliodas had changed, but then Meliodas increased the pressure to completely nail the latter to the ground. Only after Elizabeth asked Meliodas to stop was Estarossa able to get up.

Estarossa, astonished at such power, apologizes to Meliodas for having called him a fool and shows acceptance of his claim of the throne but nevertheless, mentally affirmed that he would not give up on Elizabeth. He takes advantage of the strong explosion of debris caused by the attack of Zeldris on Meliodas to appear behind Elizabeth to apparently take it, but Meliodas launches an attack with his dark matter towards his brother, which he manages to dodge, and taking several steps back.

After convincing Zeldris to help him in his eagerness to break Elizabeth's curse, Meliodas says that he can not match the power of the Demon King training or taking the Zeldris's borrowed power, and that the only way to do so is by absorbing the ten commandments of the Demon King inside his body, since the ten commandments are fragments of half the power of the Demon King. When Zeldris reveals to possess the commandments of Gowther, Drole and Gloxinia, Estarossa is very interested, after which Zeldris withdraws the commandments. Estarossa urges his younger brother to teach him how the commandments are removed from his wielder, to which Zeldris uses the spell to remove commandments in Estarossa. He is alarmed at that, but the spell does not work, which leads Zeldris to explain that commandments can only be withdrawn if the bearer gives his consent or if he finds himself powerless or unable to fight back. When Zeldris mentions that they will not be able to remove the remaining commandments as they did with Gowther, Drole and Gloxinia, which were special cases, Estarossa asks what would happen if they killed their comrades, revealing Zeldris that in such a case the commandments could be removed without problems from the corpses.

Finally, Meliodas orders them to collect the remaining commandments. Before leaving in opposite directions, Zeldris warns Estarossa not to try to keep the commandments for himself.

Estarossa left in search of Galand. so he spends all night in search of him. Once he finds his petrified body, they manage to engage in a conversation with their minds. Galand asks Estarossa to tell Zeldris to release him from his state, however, Estarossa refuses and says that would be a nuisance, proceeding to destroy the body of his partner, ultimately killing him and continuing to take his commandment.

New Holy War arc
On his way to find the Commandments, Estarossa discovers that Derieri and Monspeet were hiding in a human village. There, Estarossa uses Hellblaze to burn to death the girl who housed them and enters and teases them about playing house. Derieri, enraged, attacks him, but Estarossa quickly deals with her using his Full Counter. Estarossa then takes out the soul of the girl's corpse to eat it, but Monspeet prevent it, switching it for an apple by using his innate magic.

Estarossa then attacks Monspeet with a series of punches, managing to put him into a head lock. Estarossa states that he has come to collect their commandments, even if he has to kill them for that. Derieri and Monspeet affirms that they pretend give their commandments to Zeldris. However, Estarossa reveals that he want to take all commandments for himself.

Monspeet remarks that he is twisted and that he knows something that every Commandment know except for him. Suddenly they swap places, with Monspeet now choking Estarossa, much to the surprise of the latter. Monspeet reveals that he was waiting for Estarossa to have him completely immobilized, to use a technique called Conjurer Joke.

Monspeet continues with his story, revealing that Estarossa was born without the power of darkness, and that the Demon King gave him a commandment out of pity. Monspeet tells Estarossa that if he takes any more commandments other than his own he will die, due to the fact that having one commandment was already eating away his soul and mind. Estarossa angrily tries to get free using Hellblaze  with no effect on Monspeet and is eventually driven unconscious by him.

Thinking that they had won, Derieri walks up to Estarossa and Monspeet, asking what they should do with him. Monspeet warns for Derieri to step away, but too late. Estarossa grabs her by the neck intending to pierce Derieri, but Monspeet uses Conjurer Joke one last time, switching himself with Derieri, and having his last heart ripped out instead. After Estarossa crush his heart, Monspeet uses his strength to send Derieri flying and ignites the house on fire that engulfs him and Estarossa.

He is revealed to be alive as he flies right after Derieri to take her Commandment, encountering the new Stigma alliance after their first fight against the demon army. He excitedly notices Elizabeth and decides to kill everyone besides her using Black Hound, a dog-like figure created out of Hellblaze flames, and to create as well a circular barrier around Elizabeth and Derieri. He says it is his lucky day to find Elizabeth away from Meliodas and tells Derieri that he will send her to the same place as Monspeet once he takes her Commandment.

Elizabeth cuts him off by using Ark and crashing him into a mountain. He says how Elizabeth's rejection makes him want her all the more. Sariel and Tarmiel followed him, and commend him for taking Elizabeth's Ark unscathed. Estarossa shows false politeness as he recollects the two, asking where Ludociel and Mael were, before mockingly reminding them how easily he killed the latter.

Angried, the two Archangels use Shunenbukaki Seijin on the demon, claiming how they will easily deal with him. Estarossa forces his way through their attack and slices them both in the side with Killing Saucer. As their both bodies are covered in darkness and falling to the ground, light pierces through the black shells, and they re-emerge unscathed.

Estarossa claims that they are able to show their hatred before him yet are unaffected by his "Love" Commandment due to the Supreme Deity's divine protection against the Commandments. Tarmiel ponders on how he was able to kill Mael, to what Estarossa claims that simply he just was stronger, while he pierces the Archangel chest. However, Tarmiel melts into water by the effect of his Ocean Grace while Sariel giggles at the futility of the demon attack attempts. Estarossa attacks him, but his arm is bounced off being cut all over as the Archangel uses his Tornado Grace.

Then both Archangels trap Estarossa in a separate dimension created by their Graces, rendering him unable to break out. They claim their vengeance is fulfilled as Estarossa is torn apart by Enlil no Tenbatsu, a technique combination of their Graces, that will disintegrate him down to a molecular level to the point where no demon could regenerate.

Out of desperation, Estarossa absorbs Galand's Commandment of "Truth", causing him to possess two Commandments at the same time, giving him enough power to break free from the alternate dimension. He reappears at the battlefield, with half of his body covered in darkness, surprising everyone, who thought him defeated. Hawk assess his total power level to be now 88,000.

His demeanor is showed to have changed greatly, acting frisky and childlike. He aggressively beats both Archangels as he overcomes the protection of their Graces. Sariel and Tarmiel nonetheless, counterattacks him, leaving Estarossa quite wounded. He then realizes that even with two Commandments, he can not defeat them and has no chance of defeating Meliodas. He proceeds to absorb Monspeet's "Reticence" Commandment, causing him to go through a second transformation, this new form resembling that of Meliodas in his Assault Mode, claiming that he is "the great Meliodas". In that, he cross the chest of Sariel and Tarmiel.

Estarossa has a recollection of his childhood, sitting in a field by himself, until the Goddess Elizabeth appears and asks him if he got into a fight with Meliodas again. He says he is a coward due to being unable to kill even an insect, making him an embarrassment to his older brother. A dog was following her, and he tries to remember its name. She says he is fine the way he is. Estarossa claims he will become strong enough to end the Holy War, revealing his love for Elizabeth. He remembers fighting together with Meliodas against some Goddess soldiers. His brother praise him for doing well in the fight and when Estarossa asks if he will ever be like him, his older brother said with a smile that it is guaranteed. Estarossa keeps remembering later times, walking wounded through a forest, after he had fought and killed some Goddesses on his own, when he furtively sees Meliodas embracing Elizabeth. He thinks to himself that he did not want actually to be like his brother, but to BE Meliodas himself, as he had the power and ruthlessness he lacked along with the girl he loved.

Coming back to reality, he claims that he is in fact, Meliodas. Out of the blue he is surprised to see Elizabeth and happily ask her if she came to visit him again. Elizabeth realizes she does know him from somewhere, but does not know why her memories of him are forgotten. His attention is then focused on Derieri again, restating that he has come for her Commandment and the other nine to surpass Meliodas, but suddenly he goes back to saying that he is Meliodas as the darkness begins spreading on his body; until he breaks and begins to only repeat Elizabeth's name over and over.

Guila puts herself in front Elizabeth telling her to get behind her as she attack him. Diane and King also intervene with a defense and attack combination, with not much effect. Tarmiel and Sariel manage to cut him in three, but Estarossa instantly counters, slicing the Archangels instead. He tells Elizabeth that here it is too noisy, and they should go somewhere quiet, or he could make it quiet by killing everyone. She agrees, to keep anyone else from dying. Estarossa says there is somewhere he wants to go first with her, as he takes her off flying into the sky.

While they are flying, Elizabeth asks Estarossa where he is taking her. Estarossa affirms that they go to the place where they always went when they wanted to escape from everyone's sight, something that only she and Meliodas knew. Although Elizabeth tries to convince him that he is Estarossa and not Meliodas, Estarossa denies being the useless son of the Demon King. Then, Estarossa begins to suffer the rejection of the Commandments that absorbed, causing it to fall to the ground, but Elizabeth manages to stop his fall.

With his mind twisted by the Commandments, Estarossa takes Elizabeth by the neck and begins to hang her. Elizabeth manages to use Ark to push him away, realizing that they are in Heaven Theater, the place where she always met Meliodas. There, Estarossa tells her about how he always used to look at her, at that only person besides his brother who never made fun of him for being a cowardly demon without the power of darkness, but that the only thing that Elizabeth looked at was Meliodas. Elizabeth asks him to help her prevent Meliodas from becoming the Demon King, surprising Estarossa by worrying about Meliodas even in that situation. Estarossa begins to talk about how strong and trustworthy Meliodas is, and how he used to protect him all the time and assure him that he could talk to her about any problem or concern. There Estarossa reveals that Meliodas promised to fix things for him and Elizabeth, but Elizabeth says that his memories must be wrong. Estarossa claims that his brother lied to him, as the rejection of the Commandments gets worse, causing him to release dark matter without control. Although Elizabeth tries to help him, Estarossa locks her in his darkness claiming that if she is going to be stolen by Meliodas, he prefers to make her his by devouring her.

While being devoured by the darkness of the Commandments, Estarossa is found by King, Sariel, Tarmiel and Derieri who went in search of Elizabeth. Estarossa attacks them with his increasingly twisted mind, releasing words about Elizabeth belonging to him and Meliodas' betrayal. However, when the spell that Gowther had used 3,000 years ago began to lose its effect because Meliodas and the Demon King had begun to notice the truth, Estarossa's memories begin to return to normal. Thus, all his false memories as a demon with his brother Meliodas are replaced by the true ones as a goddess with his brother Ludociel. As the darkness surrounding him begins to disappear, Mael's original wings resurface beneath revealing to all his true identity.

Mael is in shock as he remembers how his faked memories of his "brother" Meliodas were parallel to his true memories of his brother Ludociel and how he taught him there was no sin in killing Demons. He was known as the "Angel of Death" whom the Demon Clan feared and due to his older brother's influence, saw Demons as living garbage. His worst memories were seeing his love interest, Elizabeth, fall for the "filthy demon" Meliodas and was forced to watch as his memories were twisted around and his alter-ego, Estarossa, took in Meliodas' former Commandment and caused him to lose his Grace, Sunshine. He joined the Ten Commandments as Estarossa the Love and was known as the Demon King's second son.

He is horrified to know he killed so many of his own race and other innocents and asks who was responsible for turning him to such evil, to which Gowther replies by saying it was his fault and that Mael was free to destroy him in atonement for his actions.

Mael recognize Gowther as one of the Ten Commandments and immediately attacks him with a strong knee strike. Mael takes him by the neck claiming that having made him idolize a dirty demon like Meliodas, turning his brother Ludociel into his enemy and stealing his Grace is an unforgivable sin, proceeding to attack him with a strong blow from Ark. Mael stamps Gowther's body against the ground with his foot, and tells him that before ending with him he wants to know the reason for what he did to him. Gowther tells him that it was to compensate for the balance of power that was lost when Meliodas betrayed the Demon Clan, forcing the Goddess Clan to seal them after losing Mael and thus ending the Holy War.

Mael destroys Gowther's heart necklace saying that he put him before such humiliation and pain just to end the Holy War. Mael wants to make Gowther suffer a thousand times his pain, but then Mael realizes that Gowther is just a doll. Gowther confirms that he was created by a great magician who gave his life to perform the forbidden spell. Mael lifts him by the neck, saying with dementia that he can not make a doll suffer who does not know what pain is.

Then, Mael is suddenly punched away by King's True Guardian. However, Mael quickly manages to assault King from behind saying that he would kill him to make Gowther suffer in his heart instead. However, his blow is stopped by his sacred treasure Chastiefol, then followed with Bumblebee engulfing the archangel. Mael shoots his Kyusai no Ya, piercing King's shoulder, mentioning how the technique causes a terrible pain instead of a quick death in someone who is not a demon. Gowther intervenes insisting that he is the one who should be destroyed, pleasing Mael with his expression of pain. King manages to use his Sabaki no Yari against Mael, but the Archangel catches the Chastiefol attack with one hand, saying that the more King resists the more Gowther will suffer.

Chastiefol changes back to True Guardian and hits Mael. However, he easily destroys it with an Ark beam. Mael says that King and Gowther can face him at once, being surprised when Sariel and Tarmiel appear to face him as well.

Mael greets his fellow Archangels, going on to ask them why they stand in their way protecting whoever snatched everything from him, accusing them of ignoring the mission of the Four Archangels to eliminate the Demon Clan. Mael is enraged when Tarmiel tells him that he understands how he feels, claiming that it is impossible for him to understand and that he will never be able to recover the time he lost. Sariel and Tarmiel tell him that he must get rid of the Commandments that he absorbed, but Mael affirms that those Commandments are the only hope that he has left and that if they try to take it away, he will only give them desperation.

Mael then gathers a large amount of the light power of the Goddesses and the dark power of the Commandments and uses it to attack them. Sariel and Tarmiel manage to use their Graces in conjunction with King's True Increase to stop his attack, but in the midst of another crossfire, King ends up with his arm seriously injured.

Seeing an opening, Mael goes to attack Gowther with blades of light and darkness, but is stopped by King's Increase. Mael receives no harm by calling King an annoying fly, but this gives Sariel and Tarmiel the opportunity to use their Graces to immobilize him from both arms. Continuing with her plan, Derieri jumps and starts hitting Mael with her Combo Star, wounding him to the point of death so that Gowther could learn the spell to remove Commandments. After many blows, a wounded Mael resorts to mercy in Tarmiel, claiming that he does not understand why he should always be the one who suffers. These words cause Tarmiel to free Mael's arm, allowing him to use his Sabaki no Yari to pierce the last heart of Derieri and thus claim her Commandment.

Although Sariel warns him that he will never be the same if he does, Mael absorbs the Commandment of Purity. Mael is wrapped in a huge cocoon of light as he proceeds to assimilate his fourth Commandment. Inside, Mael begins to shoot at his discretion dark rays of light, one of which hits Tarmiel.

Mael finally emerges from his light after assimilating the fourth commandment, now with a completely different appearance. All are terrified to feel its magic power, Hawk reads if power level above 200,000. Elizabeth tells everyone to run, but Mael mate makes the Love decree and uses it to perform his Jiai no Kougyoku. The attack manages to put them all out of combat, however, Gowther manages to use his Sense Opener to rid King, Diane and Elizabeth of the numbing effects of his attack. Gowther uses the Twin Bow Herritt's Range Enhancement to wrap Mael and gives King and Diane the signal to use their combined technique against him.

King uses the sixth form of Chastiefol, Yggdra Cloth, acquiring an armor with which he sets out to attack Mael. In conjunction with Gowther's Kaleidoscope technique, dozens of King's illusions appear, confusing Mael without being able to distinguish the real one. Diane proceeds to perform Drole's Dance to gradually increase King's power level. Although at first it seems to work, Mael uses the Commandment of Truth to use his Shinjitsu no Kane, dispelling the illusions and pushing back the real King.

Mael proceeds to use the Reticence Commandment to use the Chinmoku no Oogama, slashing King and Diane and sealing their magic with cursed seals, lending them unable to use their techniques. Seeing Mael preparing another Jiai no Kougyoku, Gowther jumps and clings to Mael's body, asking for forgiveness for not saving him and for having to kill him in order to save his friends. There, Gowther reveals he have a mechanism of self-destruction on him, that has enough power to kill all living within a radius of fifteen kilometers, including him. However, Mael uses the Junketsu no Kou to make Gowther to fall to the ground unable to move and make him to hallucinate with Nadja Liones.

Mael proceeds to use his Jiai no Kougyoku. However, Oslo decides to sacrifice his life receiving the attack himself.

Mael uses his attack again. However, the cursed seal is removed just in time for Diane to use Gideon's special ability, Lightning Rod, to disperse the explosion on the earth. Mael launches another Jiai no Kougyoku and Diane uses Gideon again to redirect it. There, the Heaven's Theater is broken into pieces.

As Elizabeth catches Diane to prevent her from falling, Mael appears to Elizabeth's back but before he can hurt her, King push him away revealing his new form and fully grown wings, to the great surprise of Diane and Elizabeth. King is able to hear the chaotic thoughts in the voice of Mael's heart, crying out for his sins, his desire to have Elizabeth and his intention to destroy whoever gets in his way. Mael launches a Jiai no Kougyoku, claiming that Elizabeth will be his even if it should be only her soul and her corpse. However, King emerges intact having protected Elizabeth and Diane with True Form Eight: Pollen Garden.

Mael launches to attack King, but he counterattacks with a new and more powerful version of True Guardian, hitting until Mael is badly hurt. Mael tries to use his Chinmoku no Oogama, but King responds with his new True Increase, destroying the scythe and hitting Mael repeatedly. King tries to reason with Mael pointing out the similarity in his experiences and losses, but Mael insists that he does not interfere and get out of his way. Mael launches several Kyusai no Ya, but King deals easily with it with his new True Chastiefol. Despite leaving Mael in disrepair, King says he will not kill him because revenge only brings hatred, but will face him as many times as necessary.

There, Mael's body begins to writhe and rip apart due to the power of the Commandments consuming him now that his strength and magic power were exhausted. However, before he was destroyed, Gowther jumps on him and, asking for another chance to save him, uses his Invasion to enter inside his mind.

Inside his mind, Mael is met by Gowther on the hill where he used to go when he wanted to be alone and where Elizabeth used to go to comfort him. Mael says that all he wants is to disappear quietly, but Gowther tells him that Elizabeth would not allow that. Mael insists that he does not deserve to live after taking so many innocent lives and even trying to kill Elizabeth. Gowther tries to convince him that he must be saved, but Mael says that nobody wants that or awaits his return. While Mael curses the power of the darkness that he obtained after leaving his people, the four Commandments that he absorbed materialize in in front of them, separating Mael from Gowther, ordering him to disappear from that body.

Gowther yells to Mael to expel the Commandments, but Mael is annoyed to have to endure such shame. Gowther affirms that he wants him to live to atone for his sins, and there Mael demands that he tell him the true reason why he was chosen to become Estarossa, since although Gowther told him it was because he was the only Goddess equaling the power of Meliodas, there were others like Ludociel and Elizabeth who were also on a par with him. Gowther suggests that if he has managed to remember so much, then his face should become familiar. Without understanding, Mael has a setback to an occasion in which he ruthlessly massacred a group of innocent demons who pleaded for their lives, and among them, there was a woman who looked exactly like Gowther who was crying for a last moment with her beloved before being killed. Mael does not understand who she was, but Gowther reveals that her name was Glariza, a member of the Demon Clan and the lover of its creator, the magician Gowther. Shocked to discover what he did, the Commandments begin to consume him as his body reaches its limits. Mael says that there is even a limit to his stupidity and, claiming that he can not forgive them, Mael finally expels the Commandments from his being.

Mael manages to return to its original form, and stops Gowther from his fall, to the great happiness of this and Elizabeth.

Along with Gowther, Mael takes Derieri and Oslo's corpses to another place where Mael uses Tensei no izanai to send both of their souls to reincarnate in a new life with their memories intact, stating that if they wished to punish him, then he would accept it. Gowther ask to be punished by him, but Mael ignores him. When Gowther ask him to go to Camelot with them, Mael claims if he must fight the Demon Clan as a member of the Goddess Clan, even after he made his comrades suffer and anyone wants to be near to him anymore. There, Elizabeth arrives and ask Mael to share his strength with them, not for the victory of the Goddess Clan, but to end the Holy War. At the end, Mael goes along Elizabeth, Gowther, Diane and King to Camelot.

On the way, everyone sense another great magic presence reaching Camelot. Mael recognize that it must be the four Commandments that he expelled and that they are coming to rejoin with the other five that Meliodas possess. Mael understand that Zeldris planned it from the beginning, knowing that Estarossa would eventually be destroyed by the Commandments if he tried to absorb them. Elizabeth ask if there is a way to stop them, but Mael affirms that there's not. She is alarmed knowing that Meliodas will become the Demon King if he absorbs all the Commandments, even when Diane points that Merlin still retains Melascula's, Mael knows that it wil not make a difference since the Commandments will attract each other.

When Escanor is sent flying by the Original Demon, Mael catches him poiting the irony of both of them to meet again with him in such form, saying that it must be the guidance of the "sun". Escanor recognizes him as Estarossa, but quickly understands that he is Mael.

After Elizabeth heals him, Escanor says that they are flying in the right moment to find and catch him, to which Mael says that is because King been watching the entire time, surprising Escanor with his new appareance.

Remembering the situation in Camelot, Escanor tells Mael that he heard from his brother that Sunshine was originally his Grace and that he is willing to give it back if he helps them. Mael accepts to help them but rejects the Grace, affirming that he is no longer worthy of it after having been consumed by the darkness taking it away until he chose Escanor as his new owner after waiting so long. Escanor insists that his body can no longer resist the Grace, but that they can not defeat the demons without it. As Mael continues to deny, Escanor offers to borrow it instead, asking him to save those precious to him.

Remembering his brother, Mael finally decides to borrow the Grace and when they arrives to Camelot, he uses its power to undo the Darkness spell that covered the kingdom. As Zeldris looks up, he sees that Mael has returned and refers to him as Estarossa before correcting himself.

Zeldris tells him that he must have returned to heaven as soon as he woke up, but he is surprised when Mael states that he has not come to fight since he is responsible of the Holy War and tries to convince him to retire the demon army of Britannia and stop helping Meliodas to be the Demon King.

When Mael releases his Greatest Sun against the Original Demon, Zeldris protects himself with God, reminding him that no magical attack has an effect on him. In response to his previous request, Zeldris uses his darkness to attack Merlin, overcoming Ludociel's Ark barrier by dividing it into small dark creatures. However, Elizabeth and the Seven Deadly Sins manage to protect Merlin, who has five minutes to complete the Chrono Coffin.

Mael manages to catch Zeldris' arm and throw him to the ground. Zeldris then activates his Ominous Nebula, attracting Mael with its vacuum. However, before he can attack, Zeldris' sword melts by Mael's Sunshine.

With five minutes to decide the winner, Mael and Zeldris engage in a hand to hand combat, in which Mael manages to take the lead. Mael there tries to ends the fight pacefuly reclaming that even under flase memories, they used to be borthers and that they can come to an understanding by talking.
