Tsugumi was abducted as she was returning to the apartment and taken to Nachtigal. Shiginuma Takashi tells Tsugumi that he will take advantage of her powers and have her bear his child to succeed him. Meanwhile, having ascertained that the fake cursed tomes are being made in Nachtigal, Rui and his Kagutsuchi companions infiltrate the grand building in order to put a stop to this.

During the search, Hisui comes face to face with Professor Mozuyama, who has conducted numerous human experiments.
