Tatarigoroshi-hen

Plot
Shion gets offended when Keiichi says that Satoshi transferred and quickly asserts that Satoshi never transferred and hints that Satoshi actually ran away from home. Later on, Keiichi asks Rena and Mion about Satoshi's disappearance. Rena has a obsessive episode about the curse of Oyashiro-sama and Mion drags Keiichi away from her. Mion later explains how it makes Satoko uncomfortable to talk about Satoshi's disappearance and that the mention of Oyashiro-sama causes Rena to go into a fit. Having offended several people with his questions, Keiichi begins to feel that the happy days in Hinamizawa are coming to an end.

The next day, Satoko doesn't show up to school. That day, Ooishi Kuraudo meets with Keiichi for the first time. Keichii gets a strange feeling of hatred for Ooishi despite having never met him before. After a small greeting, Ooishi asks Keiichi to find Satoko and bring her to him for questioning. Ooishi acts in a brusque manner while talking to Keiichi and ends up hurting Keiichi and drawing the attention of Irie. Irie takes Keiichi to the nurse's office and informs him that Ooishi has been harassing Satoko for some time. Irie explains the death of Satoko's aunt and the disappearance of her uncle and tells Keiichi that Ooishi is "Oyashiro-sama's servant."

Three days after Satoko was first absent, Tomita and Okamura confront Keiichi with rumors they heard regarding Satoko. Tomita claims that Satoko visited the Tomita family tofu shop and purchased an expensive silken tofu, contrary to Satoko's usual buying habits of cheap hard tofu. Okamura claims that Satoko's uncle, Teppei Houjou, has returned to Hinamizawa. Following this revelation, Satoko comes to school, visibly weaker than she was before. Keiichi, Mion and Rena deduce that Satoko is locked inside her uncle's house and is being forced into labor by him. Satoko skips club activity that day. Keiichi, worried about Satoko's well-being, visits her uncle's house to check up on her. Once he sees her, Keiichi is shocked to see several bruises on Satoko's body, which she claims are from falling down the stairs. Keiichi spends that night thinking of ways to sneak Satoko out of her house.

The next morning, Keiichi is late for school and takes a walk to the dam construction site, where he meets Jirou Tomitake. Jirou asks for directions to the Furude Shrine and Keiichi decides to take him there. At the shrine, Jirou meets up with Miyo Takano and they discuss the curse of Oyashiro-sama. After a little prodding, Miyo reveals to Keiichi who she believes will be the curse's victim this year.
