Fuminori's cold attitude toward his friends (whom he also sees as hideous monsters) worries them. After Yoh, who has a crush on Fuminori, attempts to confess her feelings, her friend Omi goes to confront Fuminori—and promptly becomes food for Saya. It is with this incident that Fuminori unknowingly tastes human flesh, finding it delicious due to his warped senses. As Koji investigates Fuminori's strange actions, Saya visits Fuminori's neighbor, Yosuke, and changes his brain into the same as Fuminori's as an experiment. Yosuke, driven insane, kills his family and assaults Saya before being killed by Fuminori.
