Keiichi learns about the curse of Oyashiro. During Rika's ritual performance at the Watanagashi festival, Shion whisks Keiichi away to sneak to the ritual tool shed of Oyashiro, where Tomitake and his friend, Miyo Takano, are waiting. Tomitake stands guard while the others look inside, to find dozens of torture tools. Takano explains the significance of the ritual tool shrine and the Watanagashi festival, and her theory that the villagers of Hinamizawa are continuing an age old tradition of sacrificing people to Oyashiro. Shion and Keiichi promise not to tell anyone they entered the shrine, though Keiichi becomes disturbed when he is questioned both by Mion and Detective Oishi about the whereabouts of Shion, Tomitake and Takano on the night of the festival. Keiichi learns from Shion that Takano was found burned to death and Tomitake committed suicide by clawing at his own throat. Keiichi starts to wonder about Shion's safety as well as his own.
