Ep. 12: Tomoya manipulates Amano to reveal the Red Star while Kikusnosuke discovers the truth too late.

12

Concerned by Kokuanten's growing interest in humans, Tomoya initiates his plan. Kikusnosuke informs the Seven that he is nearing the discovery of the Red Star's nature and how to stop Kokuanten and Tomoya. Amano waits for a call from Kikusnosuke but receives one from Tomoya instead. He reveals that the Seven harbored secret crushes on Kikusnosuke, citing their Virgin Vow of Chastity, which causes Amano distress and exposes her as the key to the Red Star. Meanwhile, Kikusnosuke uncovers Amano's role, unaware that Kokuanten's spell is manipulating her. Her immense power breaks the ward, exposing the monsters to the Seven. They arrive as Amano attempts to extract the Red Star from beneath the school. Overwhelmed by the required power, she collapses into Kikusnosuke's arms. Apologizing for her lack of awareness regarding their feelings and her own, she tries to confess to Kikusnosuke but dies in his embrace.
