第 5 集: Mari 解釋 Arume 的本質，Tsubael 攻擊 Blue，Hagino 反思重要的羈絆。

5

In the dorm, Hagino and Tsubael explain their Arume nature to a perplexed Mari. Later at school, Yuuko attempts to ask Michiko to write a script for the school festival, and Mari later pushes her to do so. Shivariel dispatches a ship to attack Blue, which is barely able to survive the subsequent assault. In his office, the headmaster collapses and is sent to the hospital, and Akane, the headmaster's daughter, is pressed to visit him by Mari. As Akane prepares to leave, she is discovered by Hagino, and Mari, Michiko, and Hiroko attempt to cover for her. Mari then tells Hagino that she helped Akane because she wanted to help her be with someone important to her. As the group sleeps, Tsubael manages to critically damage the opposing ship under Hagino's instructions, and afterward, Hagino reflects on Mari's statement about having someone important in one's life.
