Back in June 1983, the club participates in a game of "zombie tag". On their way home, they run into Irie, Tomitake, and Takano, who tell Keiichi about the yearly murders known as "Oyashiro-sama's Curse". However, he understands why his friends hid it from him and doesn't resent them for it. Regardless, this fails to reassure Rika, as she grows progressively depressed as the day of the Watanagashi Festival approaches.

Rika's plans are hindered by the appearance of Teppei, who much like in "Tatarigoroshi-hen", begins to abuse Satoko. Keiichi and the rest of the gang decide to find a way to release her from his clutches, but the government is reluctant to cooperate.
