Maya participates in paid meetings with older men in exchange for gifts and, along with Keiko, tries to encourage her friend Eri to join this world too. When Eri arranges a meeting with a man, Maya shows up beforehand to steal him, and it is soon discovered that he was murdered. Observing these events, Misa, who had transferred to the same school, begins to take action to investigate this problem.

Kazue shows her friends that an orange stain appeared in a photo with them, including Misa. It seems strange, but Misa initially doesn't notice anything wrong. When Kazue mysteriously dies and a new stain appears in Yukari's photo, Misa is sure that something very sinister is happening around her and her friends.
