The next morning, Mizutani and Tamura enter the school and find the two students alone together in the hallway. Tamura tells them that he is carrying a pen case that he made for Tamura's student, and Mizutana tells him that the case is being used by Sakurai's daughter, who has just transferred to the school. When Tamura asks if he can show him the case, he is told that it is the one that Tamura made for the student, but he does not want to tell Tamura because he fears that the girl will not believe him. He tells Tamura that he will kill the girl if she does not listen to him
