第12話: 学校祭にハギノが復帰し、アザナエルがカミオキ島事件を巡ってシバリエルを攻撃する。
As the students begin to prepare for the school festival, Hagino returns. The cast of the play then comes out in their costumes, and Michiko gains permission to prepare the hall overnight. Hagino is invited to Yuuko's classroom, where Yuuko confronts Hagino at gunpoint, and asks her intentions. Hagino reveals she wishes to protect the planet against the Arume invasion. On Shivariel's ship, Azanael accuses Shivariel of having deliberately caused the explosion of Blue's Emiru Force Drive, in order to cover up her test of a new thought-wave weapon on the Arume and humans upon Kamioki Island. Azanael attempts to assassinate Shivariel, but kills only a fake Shivariel created with her new weapon. Shivariel then uses the weapon to materialize Azanael's fears, allowing the crew to shoot her, but Azanael manages to escape. At the festival, Mari's grandmother arrives, and Mari tells her she has begun to realize why her grandmother sent her to the school. Afterward, Mari converses with Hagino, and after admonishing Hagino for not telling her about the explosion on Kamioki Island earlier, the two admit their love for one another. (Source: Wikipedia)
