Sakuma is introduced to Koutarou Douchin, a young boy contracted with Gusion, a monkey-like demon who eats the memories of others. Akutabe asks her to take him to school, but she is disgusted by Douchin's bad attitude and sexual harassment. Akutabe is forced to call upon the increasingly unstable Undine, who is revealed to be desperate for a husband. Undine takes Douchin to his school, Golgotha High, where she meets and falls for Himoi, Douchin's new homeroom teacher. She then tricks the handsome but stupid teacher into signing a contract and to say that he loves her. When Douchin accidentally breaks a vase in the principal's room, he calls upon Gusion to eat the memories of Himoi and the principal to cover his actions.
