Keiichi determines that he must kill Teppei. He asks Mion to take Satoko to the Watanagashi festival, claiming he has things to do when she inquires. Mion notes that Satoshi said and did the same before he disappeared. Keiichi concludes that Satoshi must have killed his aunt to protect Satoko and decides he must do the same. He beats Teppei to death with Satoshi's baseball bat and buries the body. On his way back home, Keiichi bumps into Takano, who appears to know of the murder he committed when she asks him if he buried the body.
