In the Program[]

When Yoshio hears his name called, he starts to cry and as he leaves, he debates the situation. In fear of dying he returns to the school, just in time to murder Mayumi Tendo with his crossbow. As Shuya comes out, he is almost persuaded to join Shuya and to stop playing but he suddenly goes mad again as he thinks of the reactions of the others after they discover he killed Mayumi. At this moment, Noriko Nakagawa walks out and Yoshio aims at her. In retaliation Shuya knocks Yoshio off the school's entrance roof by hurling an arrow into his shoulder.

As Yoshio begins to regain consciousness, he realizes that he lost his crossbow. He looks around for it and doesn't realize that Kazushi Niida is behind him. Kazushi shoots an arrow at him which penetrates the side of his head.
