Dr. Ogami now has to deal with a patient who has a violent record. He is trying to solve a murder mystery for the police. He performs tests on him, while Kaoru Satsuki teases him. This causes him to become nervous. He also constantly stares as Nanako, as if she is of importance to him. He turns into a "Hyde" monster and wreaks havoc on the Ogami Hospital. Many attempts of falsely torturing Nanako, including stripped her down to only her panties and being tortured by Kuron, hanging her above a boiling pot of goo, topless with only nipple shields to cover her big breasts in a torture ritual, and a near-lesbian scene where Satsuki tries to "make her into a real woman," all fail. They attempt to shoot tranquilizers into the monster to stop it, but all fail, and, in turn, make everyone else except Dr. Ogami go to sleep. While cornered outside in the rain by the monster, Nanako is saved by Dr. Ogami, who manages to put it to sleep. The next day, Nanako goes over to Satsuki's room, hoping to ask her about "making her a real woman", but not the way Nanako thought. However, Nanako caught Satsuki at a bad moment... without her makeup on!
