The Royal Library in the Royal Academy of Magic in Olympus. The head of the library committee, Unico Wingedhorse, is being attacked by a tentacle monster. A ball of light comes to Unico, whose entire body is covered in white muck, and frees her from the tentacles. The ball of light is Dante, the Grimoire. After being manipulated by the Grimoire of Lust, a young girl named Patricia Garlondo (Patty) begins masturbating in the hallway of the school. A group of men comes to pick her up. The grimoire of "Sexual Desire" puts up a ward and manipulates Patty's body to engage in an orgy with the men. She sucks up the magic power of the men along with their sexual desires. Dante senses the vibrations of the Grimoire of Lust. When Unico rushes to the school with student body president Bunka, he sees the manipulated Patty attacking students all over the school with her tentacle demons.
