The story's focus is on the Occult Club at Akademi High School and what they do.
Oka sees a murder, and begs Yandere-chan not to kill her, who doesn't. She stays silent for a few days, before starting to cry during an Occult Club meeting. The other members ask her what's wrong, and, after checking nobody was near the Occult Club's room, she told the other members. They are shocked, but don't tell anyone. Oka goes to stalk the Basu sisters to forget the murder, but Inkyu was gone. Sakyu was by herself, crying. Oka asks her if she's okay. Sakyu says Inkyu's dead. Oka confesses she saw the murder, and should have gotten helo. Sakyu is not mad. Oka asks Sakyu if she wanted to help bring Yandere-chan down, to which Sakyu accepts.
