Shion is attacked by Gnosis on the cruiser Voklinde. The one that saved the crisis was KOS-MOS, where Shion was the chief development officer. However, KOS-MOS tries to secure Zohar according to a mysterious command that even Shion does not know. Because of this, Zohar was taken away by Gnostic, and Vokhlinde sank. Shion barely succeeds in escaping and later encountering a young man named Chaos. On the other hand, KOS-MOS was in contact with Elsa, a passenger ship that appeared in the air after the end of the battle for the remains.
