Due to his infection, Messer is reassigned, but not before he expresses his gratitude to Kaname at the Jellyfish Festival. Realizing that the Windermereans have only attacked planets with ruins, Walküre and Delta Flight go to the last such planet, Al Shahal, and singers from both sides try to gain control of the ruins. Delta Flight are losing a battle against the Aerial Knights when Messer returns to save Kaname and fight Keith.
