The grimoire grants her wish, and she is rewarded with a luxurious mansion, lavish meals, and a doll that has become a human being, who calls her sister. Eva's heart is stolen by the grimoire, and now the grimoire tells her what she wants. She wants the magical power of Unico of Olympus Academy. One day at the library, Unico hears about the new Knights of the Library and greets Miya. She is shown a picture of one boy, Adam, who seems to be involved with Grimoire. In the back alleys of the town, a pair of men and women are indulging in an intense affair. The girl was a toilet woman who had been rumored recently. The man gets carried away and says he's going to invite his friend. Hearing this, the girl's body changes and she takes the form of a boy. It was Adam that Miya had been looking for.
