11

Tsubael brings Mari to the surface, asking her to stop blaming Hagino. At school, Mari’s lack of motivation for the play angers Michiko. Hagino cries in Onomil’s room, where a projection advises her against self-blame. Azanael returns to Shivariel’s ship and learns that multiple vessels are being sent to destroy Blue. Mari speaks with Hagino’s projection, and after seeing Arume ships in the sky, she secures a promise from Hagino to return and finish their discussion. Yuuko witnesses this interaction. Hagino and Tsubael barely survive the attack, aided by a system activated by the phantom Onomil. Meanwhile, Azanael discovers that the explosion on Blue five years ago, which killed Onomil, was not an accident.
