Demon Slayer has its fair share of shocking and emotional character deaths, so what makes Akaza’s death so meaningful? He’s a demon, after all, and one of the show’s antagonists. Well, there’s more to Akaza (and his death) than meets the eye, and we’ll explain how. In this deep dive, we’ll take a look at Akaza’s death in Demon Slayer and its significance. We’ll also discuss the fan reaction to Akaza’s passing, and why people care so much about the fearsome—and complicated—Upper Rank Three!

Akaza’s Death in Demon Slayer, Explained

Although Akaza—the Upper Rank Three demon—dies in a battle against Tanjiro and Giyu, neither of them kills him. Rather, after being beheaded, Akaza wills himself to stop regenerating, choosing to die. His human memories return to him, and Akaza decides he’d rather die as a man than fight on as a demon.

   Akaza battles Tanjiro during the Infinity Castle arc. During the Demon Slayers’ attack, Akaza ends up in a fearsome battle against Tanjiro and Giyu. Although initially mocking Tanjiro as weak, Akaza quickly realizes he’s grown stronger—but the real shake-up happens after Tanjiro argues against Akaza’s strength-obsessed beliefs. Annoyed, Akaza starts to contemplate why he feels the way he does and begins to recover his human memories.

   • At one point, Tanjiro actually decapitates Akaza, briefly stunning him. However, decapitation doesn’t kill Akaza; he’s able to keep fighting and start regenerating through pure willpower.

   Akaza’s memories lead him to self-destruct. As he starts to recall his human self, Akaza sees a vision of his fiancée, Koyuki, begging him to stop and asking him to “go to the other side” with her. Initially, he refuses, insisting that he needs to get stronger…until he’s flooded with memories that remind him why he was so desperate to get stronger. In the end, he decides that Tanjiro has fairly defeated him and wills his body to stop regenerating.

   • By the time Akaza accepts death, he’s almost fully regenerated. Muzan’s will even manifests and tries to force him to keep regenerating, but Akaza reverts to his human self and embraces Koyuiki instead.
   • In the end, Akaza’s body crumbles into ash—not because a Demon Slayer killed him, but because he voluntarily let it happen.

   Akaza chooses to die for the sake of his humanity. In recovering his memories and reflecting on his life, Akaza makes the choice to die as a man rather than a demon. He dies despite Muzan’s protests, with Koyuki reassuring him that she’s just glad he remembers her again. Decapitation should have killed Akaza, but Akaza’s own refusal to be “weak” let him fight on—and later, his desire to be with his loved ones allows him to die.

   • In short, Akaza dies simply because he refuses to keep fighting. Overcome with memories, he chooses death over continued existence as a demon.

Akaza’s Backstory in Demon Slayer

1. 
   1
   Akaza’s human life was one tragedy after another. As a child, Akaza (or Hakuji, as he was then known) struggled to care for his sick father. He stole and committed criminal acts for survival, and often endured brutal punishments for his actions. His father, not wanting that life for Hakuji, hung himself—leaving Hakuji heartbroken and alone. Later, Hakuji’s talent for martial arts was discovered by a dojo master, Keizo, who let Hakuji live with him and his daughter, Koyuki.

   • While training with Keizo, Hakuji also helped care for Koyuki, who suffered from a long-lasting illness.
2.

   Hakuji grew close to Keizo and Koyuki, but lost them, too. Over time, Koyuki grew stronger thanks to Hakuji’s care, and Hakuji became an exceptional martial artist. Finding a new home with the pair, Hakuji was eventually asked to take over the dojo and marry Koyuki, both of which he happily accepted—yet this bright future was stolen from him.

   • A rival dojo tried to best Hakuji, but failed. In retaliation, they poisoned the water at Hakuji’s dojo while he was away at his father’s grave—and when he returned, Keizo and Koyuki had died.
   • In a rage, Hakuji brutally slaughtered the entire rival dojo, furious over his loss (and his own guilt at being unable to protect Koyuki as he’d once promised to do).
   • The bloodbath caught Muzan’s eye, and the Demon King proceeded to exploit Hakuji’s grief and rage. Hakuji accepted the offer to become a demon, and as Akaza, his human memories were wiped away.

The Significance of Akaza’s Death in Demon Slayer

1. 
   1
   Akaza’s death represents humanity’s triumph over corruption. As he regains all of his memories, Akaza is finally able to feel regret over the decisions he’s made. He disregarded his father’s request for him to live honorably, defiled his mentor’s martial arts style by using it for murder, and got so wrapped up in self-hatred that he let it drive him to evil. Choosing to die is Akaza’s way of embracing his humanity, stopping himself from doing any more harm.

   • Because Akaza’s death was the result of his regret and grief, it proves that he still has humanity left, despite all the years spent as a ruthless demon.
2. 
   2
   Akaza’s death is also an act of defiance and redemption. Muzan is the one who commanded Akaza as a demon, and he was fighting on behalf of Muzan—so, when Akaza decides to stop fighting and let death take him, it’s effectively a rejection of Muzan, too. Akaza is refusing to be Muzan’s puppet anymore in the only way he can, and defying Muzan’s orders to eliminate the Demon Slayer Corps.

   • Few demons have the humanity and willpower to defy Muzan. Despite the tragedy of his death, Akaza also shows extraordinary strength—simply by letting go.
3. 
   3
   In death, Akaza becomes Hakuji once more. As he passes, Akaza reunites with his father, his former mentor, and finally, his fiancée, Koyuki. Embracing him, Koyuki finally gives Akaza the closure he’s needed all along: she assures him that he’s done enough, alleviating his deeply ingrained guilt. Although Muzan tries to reel him back and force him to keep fighting, Akaza’s human side wins out. As Hakuji, he chooses a hopeful afterlife with his lost love.

   • The human Hakuji had noble intentions, but his grief and pain were exploited by Muzan; in rejecting Muzan, Akaza is able to return to his former self, too.
4.

   His death marks the end of Akaza’s story arc on the show. Akaza’s story arc is all about obsession and corruption. He was obsessed with strength, a twisted reflection of his need to protect his loved ones, and his self-hatred over the fact that he failed to do so. Manipulated by Muzan, Akaza led a tortured existence; in the end, however, he realizes the truth behind his obsession and rejects it, choosing redemption instead.

   • Muzan tries to hold onto Akaza by telling him he can only keep his promise to Koyuki (whom he swore to protect) by getting stronger. After believing it for over a century, Akaza finally breaks from Muzan’s manipulation.
   • The culmination of Akaza’s arc shows how dangerous guilt and hatred can be, especially when directed inward—and that the path to redemption lies in forgiveness.
5.

   Akaza’s death is also a precursor to Muzan’s ultimate defeat. Akaza is one of Muzan’s favorites, and an exceptionally strong member of the Twelve Kizuki—so, on a practical level, his death strikes a major blow against Muzan’s defenses. Without Akaza, Muzan’s forces are left vulnerable, allowing the Demon Slayers to advance. In short, losing Akaza weakened Muzan, paving the way to the Demon Slayers’ victory over the King of Demons.

Fan Reactions to Akaza’s Death in Demon Slayer

Download Article

1. 1
   Fans regard Akaza’s death as one of the show’s most emotional moments. Demon Slayer doesn’t pull its punches, and plenty of its characters meet a tragic end. Yet fans were especially moved by Akaza’s death—one of the show’s antagonists, who personally killed Kyojuro Rengoku. But it’s understandable; he might have been a “bad guy,” but Akaza’s life was a tragic one, and his death is a poignant combination of hope, sadness, redemption, and loss.

   • Given his tragic backstory, fans were surprisingly sad about Akaza dying, too. Death was ultimately his salvation, but it was still a reminder of his difficult life.
2. 2
   Fans also laud Akaza for being an excellent, complex villain. Akaza’s death proved that he was more than just a villain. He’s complicated and multidimensional, and his villainy is a product of misfortune beyond his control. Basically, it’s easy for fans to empathize with Akaza and pity his downfall, because he was ultimately taken advantage of at the absolute lowest moment of his life—and who wouldn’t struggle with that?

   • That’s not to say Akaza is blameless; he’s still responsible for (presumably) many atrocities over the years beyond even the ones we know about.
   • But he’s also not a black-and-white villain or someone who set out to become one; his motivations are understandable, even if they’re wrong. It’s what makes him so compelling as a character!

Who is Akaza in Demon Slayer?

1. 1
   Akaza is the Upper Rank Three, a powerful demon loyal to Muzan. As a member of the Twelve Kizuki, only two demons outrank Akaza: Kokushibo and Doma (which just goes to show how powerful he is). Before he was a demon, Akaza was a human martial artist of amazing skill named “Hakuji.” But, after enduring a life of personal tragedy, Akaza was enticed into becoming a demon at Muzan’s invitation.

   • Age: 133 (as a demon); 18 (as a human, before transforming)
   • Height: 5 ft, 8 in (173 cm)
   • Combat style: Destructive Death
   • Description: As a demon, Akaza has near-white skin with a pattern of blue lines running across it. His eyes are yellow with blue sclera resembling cracked glass, and he has short, pink-red hair.
   • How did he become a demon? Losing his mentor and fiancée made Akaza lose the will to live. Muzan, impressed by Akaza’s ferocity and talent, manipulated Akaza into becoming a demon with no memory of his past life.
2. 
   2
   Akaza famously wants to be the “strongest,” and only respects the strong. As a demon, Akaza is a fervent social Darwinist—he believes the strong survive and the weak must perish. He’s one of the few demons to respect his enemies, provided they prove their strength. When he encounters a Hashira (like Kyojuro Rengoku), he even offers them the opportunity to become a demon, too.

   • Akaza also has an obsession with strength that drives him to keep getting stronger. He wants to be the strongest entity possible, to the point that he resents the two demons outranking him (Kokushibo and Doma).
   • Although he doesn’t remember his human life, shreds of his old humanity still poke through in subtle ways.
   • For instance, despite his obsession with strength, Akaza refuses to kill or eat women—something his fellow Kizuki have no qualms about.
