Ooyukiumi no Kaina: Hoshi no Kenja

Kaina and Ririha helped end the conflict between Atland and Valghia, finally creating the peace both sides desperately needed. One larger problem remains untouched, however: the resources of the Snow Sea continue to disappear, and without an answer, peace itself may soon become meaningless.

Kaina returns to the icy Canopy before setting out with Ririha and a small party across the Snow Sea in search of a colossal orbital spire tree believed to hold a path toward humanity's survival. Their expedition carries them beyond the lands they know and toward secrets about the true nature of their world. After fighting to stop a war, they now have to prove that there can be a future in which both former enemies are able to live at all.
