Sezon 0

Summary of the first (A Letter From Katue) half of the anime.

Summary of the second (13 Meet Again) half of the anime.

This episode is a sidestory and can be inserted somewhere between episodes #18 and #21. This is a "mystery" and so the present writer does not tell the whole story. The Janus is sailing towards Taut when something unexpected happens.

The story takes place in Kukto in D.C. 2060 - a year after VIFAM. Ypserlon has been restored to peace, though there still remains occasional skirmishes. The Thirteen are invited there for a ceremony by the new Kukto government (its members are formerly the rebels). As two unexpected people appear, they develop a new story. It is a quest for memory.
