With Rika promising she can get Satoko to promise to admit to being abused, the CCC calls Satoko's house. Her uncle stands behind her, reminding her that if she tells them anything, he will beat her, and then destroy Satoshi's room. However, Rika tells her that letting her uncle abuse her isn't strength, and that if she were really strong she would let everyone help her. Satoko finally admits to being abused, and her uncle is arrested. Rika tries to warn Tomitake and Takano that they will be killed on the night of the Watanagashi, but they ignore her. We find out that Tomitake was sent to Hinamizawa to prevent an outbreak of the disease that existed in the town long ago, while Takano was hired to stop him. She injects him with the syringe containing the disease, which makes him go crazy and tear his own throat out, much like keiichi did in the first arc, while Takano fakes her disappearance, leaving behind a corpse for people to find as her own.
