The Sorority members have a special study session at Fukiko's house. Fukiko invites Rei to join them, telling her to wait under the elm tree at five o'clock, but doesn't arrive. Nanako returns to school that night for her notebook, and finds Rei waiting under the tree, soaked from the rain and delirious with fever. Nanako tries to take Rei home, but she resists, unwilling to break her promise to Fukiko. Rei attempts to walk through heavy traffic and jump off a bridge in order to get back to the tree, but Nanako manages to stop her. She finally brings Rei home, but discovers that Rei lives alone in a dark, dreary apartment filled with mirrors. In her delirium, Rei thinks that Nanako is her treasured doll and hugs her.
