The demon killed the children, save for one girl, and Gyomei fought it to save her. The girl's remarks afterwards were misinterpreted and he was imprisoned, leaving him cynical and distrustful.

As the Hashira are summoned to the mansion, explosives level the area, sacrificing Kagaya and most of his family to stun Muzan. Tamayo appears and injects a human-conversion drug into him before Gyomei decapitates the demon with his flail, which fails to kill him.
