The openings to the darkness which were sealed by Shirogane opens up causing a weird thundering red-sky phenomenon. Kou is shocked by the numbers of Kokuchi's at his area. Haruka appeared and tells Kou he suspects that there's a spy among them. Akira, Kengo and Aya ran to Kou-nii during the attacks in their school. Kou tells Haruka to repeat what was in his mind and at the end of the sentence, Shirogane appears with his usual flirty smile. They fells betrayed Kou and Shirogane fights because Haruka says that Shirogane's the spy and told out the evidence. Ruru saves Shirogane confessing that their plan is revealed. Shirogane denies it and brought Akira up to an abandoned building. He whispered something in his ears, standing really close and intimate. Kou comes in and dives from a few floors with Shirogane. He sacrificed himself to kill Shirogane.
