The next day, detective Kuraudo Ooishi confronts Keiichi at school and asks if he knows either Tomitake or Takano. Ooishi tells Keiichi about the series of mysterious deaths and informs him that both Tomitake and Takano have been missing since the night of the festival. Ooishi asks that Keiichi keep their meeting a secret. Later, Keiichi asks Rena if she's hiding anything from him. Rena asks him the same question and becomes angered when he lies. Rena reveals that she knows about Keiichi's meeting with Ooishi and claims both of them have secrets they are keeping.
That night, Ooishi calls Keiichi and reveals Rena's troubled past in Ibaraki. Keiichi's father brings him tea and informs Keiichi that he had sent Rena up to his room. Keiichi realizes that Rena overheard his conversation with Ooishi.
