Ooyukiumi no Kaina

A world-spanning ocean of snow keeps growing, and its people struggle to survive across the frozen landscape. Some gather around the enormous tree roots scattered over the surface, while others live high in the canopy that covers the planet’s atmosphere. Kaina, a young woman from the canopy, and Liliha, a young woman from the surface, meet by chance. Their encounter sets in motion a series of events that will change the course of their world.
