Two Sorority members, Ogiwara and Komabayashi, persuade Aya's friends, Miyuki and Megumi, to steal and burn the petitions. Rei stops them. Aya intentionally takes the blame to protect the girls, saying that she'd ordered her friends to do so. Mariko reminisces their rivalry to Nanako and Tomoko. That night, Aya attempts to drown herself in the ocean, but the three of them save her: Megumi and Miyuki revealed the truth to them and Kaoru, and they've been searching for her. Mariko and Aya rekindle their lost friendship, and Aya signs the petition the next day.
