Demon Slayer Manga Chapter 155

Hakuji finally begins to see a future he never thought was possible. Koyuki’s health improves, and Keizo offers him the chance to inherit the dojo and marry his daughter. For someone who once believed he had no place in the world, the idea of having a family gives Hakuji a reason to live and protect the people he loves.

In Demon Slayer Chapter 155, that happiness is destroyed when Koyuki and Keizo are poisoned by a rival dojo while Hakuji is away. Overcome with grief and rage, Hakuji attacks the rival dojo and kills all 67 members with his bare hands. Soon after, Muzan finds him and offers him demon blood. Broken by the loss of everything he cared about, Hakuji accepts and begins the transformation that will erase his human memories and create Akaza.
