Episode 9 hit and it's a game changer.
While Chihiro's on his way to be frozen, the thought of never seeing Iyu again causes him to hulk out into this monstrous Amazon form and starts laying waste to everything, while killing Tachibana and Kano. When Chihiro turns back to normal, he runs away after relizing what he did. Kurosaki straight up tells Iyu to kill Chihiro.
