Ginga Hyouryuu Vifam: Keito no Kioku - Namida no Dakkai Sakusen

Fuente: AniList

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.
