Ritsuka finds Shiki in the school garden destroying thorned roses with his bare hands. She stops him and Shiki tells her that he was doing so because he thought that she might want to help him. Shiki reveals to Ristuka that he is a fallen angel. He suddenly tells her that he may know the whereabouts of her mother and he offers to take her there. Ristuka is hesitant, due to her previous encounters with the other members of the Student Council, until Azuna interferes. Shiki allows Azuna to accompany them. He takes the girls to a nearby art museum with many hallways like a maze. He disappears and Ritsuka gets separated from Azuna, becoming lost. While wandering around the museum, Ritsuka catches glimpses of her family's past until Shiki grabs her from behind. He tells her to become his, but Ritsuka pushes him away, prompting Shiki to use his powers to freeze her. He threatens to kill her if she doesn't comply, but Azuna intervenes by repelling him with a capsule of holy water. She attempts to exorcise him, but Shiki reveals that he can't be exorcised due to the angel blood within him. Black wings sprout from his back and he attacks the girls, wounding Azuna in the process. As he is about to kill her, Ritsuka convinces him to stop, and he teleports them back to the school garden where they first met. As Shiki begins to leave, Ritsuka asks him if he lied about knowing where her mother is, but he only replies by saying that lies are truth before disappearing.
