Episode Description:
Tsubael takes Mari back to the surface, and implores her not to blame Hagino. Back at the school, Mari finds that she lacks any drive to participate in the play, resulting in a furious reaction from Michiko. Meanwhile, Hagino weeps in Onomil's room, and is confronted with an image of her, who tells Hagino not to blame herself. Azanael then returns to Shivariel's ship, and finds that Shivariel is sending multiple ships to destroy Blue. At the school, Mari converses with Hagino's projection, and, after seeing Arume ships dot the sky, she elicits a promise from Hagino to return to finish their talk. However, their conversation is seen by Yūko. Hagino and Tsubael barely manage to survive the assault, with a key system coming online due to the phantom Onomil's efforts. At Shivariel's ship, Azanael discovers that the explosion on the Blue five years ago that killed Onomil was not an accident.
