The Banten shinobi and Grey Wolves are under attack by the students at Alya Academy. Raimei tries to talk Subaru out of fighting, but Subaru reveals that the brains of young shinobi are the main ingredient for the forbidden cure-all Daya, which she wants to use to revive the school’s headmaster, who is dying of a chronic disease. They capture Raimei, Juuji, and Miharu, but Yoite’s brains are judged useless and they run him through with a sword. Meanwhile, the adults are still fighting upstairs with Kouichi, but they can’t get into the basement where the other kids are until Kannuki shows up, capturing Kouichi and forcing the others to surrender their weapons. Kannuki reveals his own plans to mass-produce Daya and gain huge profits for Alya Academy, and Yukimi starts the fighting again. While Kumohira tries to stop Kouichi from ruthlessly beating Kannuki, Kouichi gets shot. As he dies, he warns Kumohira that others will die in a similar manner because of him and his ideals.Down in the basement, Miharu’s desire to help Yoite and prevent him from dying has unleashed te Shinra Banshou. Kumohira attacks him and gets him to stop, but then Tasuku turns on the rest of the student council, locking everyone in the basement where there is no air. He goes to get the Daya scroll from the headmaster and reveals that he has been working for the government’s secret intelligence squad Kasa the whole time. Kouichi shows up, revealing that he can’t die, and beats up all the Kasa guys; Tasuku kills himself so as not to be killed. Kouichi and the headmaster let everyone out of the basement, and the headmaster’s life finally comes to an end. Shijima, who has been entrusted with the Daya scroll, gives it to Miharu, and in a conversation with Kouichi, she reveals that she is actually Miharu’s cat Shiratama.
