Morizono Aguni, also known as Agni, is a character who first appears in the Beach arc and is the leader of the Militant Sect.


Agni is an extremely strong and muscular man with short hair and a light goatee. Following his Six of Spades game, he ended up with 3 long scars running across his left eye and cheeks. He is frequently seen wearing camouflaged clothing and carrying a firearm.


Agni can be very harsh and blunt, but does have a compassionate side, especially when he met Hayato Dōdō and Akane Heiya. He is also quite reckless, as seen when he charged at the hyena in the Six of Spades and when he charged at the King of Spades. However, he seems to have an extremely high pain tolerance as even getting shot my multiple bullets doesn’t stop him from charging when he has his mind set. He’s a very tough person, and a lot of that stems from his childhood trauma and the gang activity he and Danma were involved in prior to the Borderlands.


Before Borderland

Agni's father was an abusive alcoholic. He constantly beat his son and wife after returning home carrying another drink. To draw the attention away from his mother, the frightened Agni retorted his abusive father but his mother did not stay long in their home, traveling the world and abandoning them. Agni also ran away from his father when he was 12 years old. Agni and Takeru Danma (Hatter) had been sworn friends when they were 16 years old. Both messed with bunch of street thugs but easily crushed them with just 2 men. After urning 17 years old, Agni wanted to beat his father for revenge, only learned that he died of acute alcohol poisoning half year after Agni's leave.

Forming the Beach

After winning some games, Agni helps Hatter to establish the utopia. Together they recruit Suguru Niragi, Rizuna An, Yūji Mahiru, and Keiichi Kuzuryū. They quickly work out the logistics; rain water could be used to drink, and they can use gasoline to power generators to run the ultimate paradise.

The Beach

After a while, the number of violent people within the Beach grows. Hatter realizes there still isn’t enough hope, and combats this with a lie— once a person collects an entire deck of cards, they return to Earth. With that, new hope is found and the number system comes into place, with Agni being #2. Hatter told Agni that he doesn’t mind if he set up a militant faction against him. Doing so keeps the trouble makers under control so they do not disturb the equilibrium of the Beach society. Agni questions if he’s trying to become a king, but he agrees to assume this role, until Hatter murders the residents for hiding the cards which should be handed over for the society. Agni is horrified that Hatter has become so mentally unstable he can’t even recall that he fabricated a lie. Their friendship slowly starts decaying.

Six of Spades

It’s in this game where Agni is introduced for the first time. As a women is about to be eaten, he shoots her out of mercy, letting her die as bait. A drooling hyena approaches him, but his gun is jammed. He laughs and throws it aside. They both charge towards each other, but Agni wasn’t careful and let the hyena scratch 3 massive lines across his face. He jams his thumbs into the hyena’s eyes and crushes its face apart.

Death of Hatter

The next morning, Agni can be seen wearing a thick bandage around his wound. Later that night, disappointed by Hatter's heightened spirit of brainwashing the residents with the false method of departing the Borderland, Agni calls out Hatter right after the latter has just been returning from game and bids farewell. Hatter points his gun on the back of Agni but he quickly shoots back and kills him, only to then learn that Hatter's gun is not cocked or even loaded. He finally understands that Hatter has been concealing his fear of being unable to escape the Borderland. Hatter would rather die in his best friend's hand than by anything else. Agni is devastated.

Ten of Hearts

When the Ten of Hearts (Witch Hunt) begins in the next evening, he orders his underlings to murder anyone not in their sect, even including the other executives. They believe that they are merely doing what the game requires them: Throw the "Witch" into the bonfire before timeout, regardless of how many lives that will cost. Initially, Taketo Serizawa express doubt at this method. He says that even if they burn the Witch this way, they’ll never be able to return to their original lives after the amount of people they killed. Agni punches him, and states that volition, not courage, is needed to survive in this world. Those who dream die, so he needs to wake up. Later, Taketo approaches him again and pleads that he can’t continue the game, and Agni throws him out a window. The truth is, Agni wants to lead everyone to game over so all Beach residents, including himself, are buried with the false hope spread by Hatter. Even hearing Ryōhei Arisu’s revelation of his true motives and reasoning, Agni still beats him horrifically. Right before Arisu states the Witch’s identity, he punches another Militant member and claims himself to be the Witch. As he fights off countless people trying to attack him, he doesn’t falter. Arisu realizes that the reason he won’t stop his own rampage isn’t because he can’t stop himself, it’s because he has no reason to. His rampage is only distracted when Asahi Kujō reveals her true identity as the dealer which activates the blazing laser of execution. With the silence, he begs 1 last time for Agni to allow them to clear the game, and he abstains. The game has been cleared, but the Beach resort is destroyed in fire set by Niragi. Agni hides himself from the crowd, probably out of guilt.


During the Interval, he overhears 2 guys talking. 1 of them says something weird happened; on the venue, there was no game, but instead just a register that read “INTERVAL”. When he hears this, he is very shocked.

King of Spades

With the Second Stage upon him, Agni sets up his lone garrison in a forest away from the city center awaiting Shīrabi (King of Spades)'s approach. He wants to atone his sin via a meaningful death. After encountering Hayato Dōdō running for his life from Shīrabi, he does not hesitate to point out how cowardly and useless Dōdō is for surviving all along over the sacrifices of others, but decides to train him in the vague hope of outnumbering Shīrabi. At night, the King of Spades ambushed them and sets the forest alight. Dōdō still proves not much of a helping hand when he is commanded to aim and shoot Shīrabi in a crossfire. Agni lets Dōdō run away and rushes himself towards Shīrabi, the latter is impressed by Agni's resolve and retreats. Sometime later, Agni again saves Dōdō from the torrent and meets Akane Heiya after the latter two have destroyed Shīrabi GPS device. Agni is hugged by Dōdō for feeling sorry and grateful that they are still alive. The 3 head into a grocery store to recover and eat. Agni is also asked by Heiya if he would be interested in her sexually, to which Agni instantly rejects her. Besides the possibility of being gay, Agni has been prepared to sacrifice his life anytime soon, hence his rejection to getting involved with other people. After hearing Dōdō's comment that they are like a family even though their ages do not line up, Agni secretly admits to Hatter's shadow created by himself that he will assume the duty of a father to protect his own son. As the banter continues, Dōdō has the terrifying revelation that his visa expires that day. Agni tells him to get some rest for now and worry about it later. Just when Dōdō and Heiya are asleep, Agni quietly leaves to somewhere to set up a leaking fuel trap for Shīrabi which would kill both of them, but Dōdō quickly approaches Agni, refusing someone to die for his sake. The 2 rush onto the roof of the building and are at a dead end, Heiya emerges from a lower building and shoots an arrow at a nearby car, tied with rope. Dōdō slides down on a sling and he follows suit, but doesn’t see Dōdō at the base. To Agni’s horror, he stayed behind to slow Shīrabi, but all shots are voided by the bulletproof vest. Dōdō loses his balance after being nicked hit by Shīrabi's shots and falls into the mud flow below. Shīrabi then uses the same wire to approach Agni, but the building crumbles and he falls into the top of a van. Agni, in deep despair over Dōdō's apparent death, has everything crashing down: Hatter died, Arisu was beaten nearly to death, and now Dōdō died, all because of him. With nothing left to lose, he charges towards Shīrabi, taking numerous shots before closing the distance and punches Shīrabi's head hard before snapping his neck. Before dying, Shīrabi mutters his regret for not being able to save his former commrade Apache, Agni assumes this comrade and forgives Shīrabi. This also gives Agni salvation for his regret over Hatter's death. As he kneels, Hatter appears once more and commemorates his redemption, and shares a heartfelt apology for the burden he placed upon him. As he leaves, he says it’s the last time he’ll show himself and wishes him good health. Rejoicing their victory and Dōdō's survival, the announcement declares only Agni's visa is extended instead of anyone else, this leaves Dōdō in deep peril as his visa will expire that day. However, only 1 game remains so the 2 let’s Agni rest as they head to the final game venue. The last game, Queen of Hearts, is cleared by Arisu and Yuzuha Usagi in the same day.

After Borderlands

Agni, like his allies, chooses to return to the original world, he is last seen unconsciously lying in the hospital bed, watched over by Dōdō and Heiya who preserve no memory of their time in the Borderland but feel a faint bond tied with each other.

I am trying to find a place where I can die. Will the King of Spades be able to give me that?

- Morizono Aguni, chapter 49.1


  • The name Aguni, especially his nickname Agni, is a play on the word agony, and they sound similar. This is a reference to the character parallel between him and Shīrabi, and the latter trying to understand agony.
  • If Agni had accepted permanent residency, he likely would’ve become the new King of Spades.
