Demon Slayer Manga Chapter 156

Akaza’s battle reaches its final moments as his memories of Hakuji begin to change the way he sees himself. Tanjiro’s determination reminds him of the person he once was, while the fighting style he learned from Keizo makes him realize how far he has fallen. For the first time in centuries, Akaza begins to understand the pain behind his own actions.

In Demon Slayer Manga Chapter 156, Akaza turns his most powerful attack against himself and finally accepts that he has lost. Even Muzan’s influence cannot keep him fighting forever. When Koyuki appears and calls him by his human name, Hakuji, the demon finally lets go. With tears in his eyes, he apologizes for failing to protect her, and his body fades away after finding peace at last.
