Crimes in which young women were slashed in the face were occurring one after another. Ochiai-sensei talks to the members of the Hadogumi about the special psychology of these "pleasant criminals" and the "spiritual spring" that humans need to survive. Hiroshi and his friends are impressed. However, Ochiai-sensei himself has been dumped by Junko-sensei many times and seems to be losing the spring in her heart. So Takeo tries to support the teacher.
