Episode 16 Episode 16

The Neo UN fleet, taking control of the Alvis base, is faced with a new Festum that begins to assault the island. It is shown that Seri Tatekami was with the female island core, recognized as Tsubaki Minashiro, before she returns back to the base. Chizuru later finds Tsubaki and takes her to the lighthouse. Tsubaki leads Fumihiko and Soushi into a second command center. Mamoru, Kenji, and Sakura barely put up a fight against the Festum, as they are consequently defeated. Kazuki, in the Fafner Mark Sein, arrives in time, synchronizes himself with Soushi, and eradicates the Festum using a rifle gun and then a lance sword.
