SF/Fantasy visionary Tsutomu Nihei's most accessible and exciting series yet! With a strong influence from classics like Nausicaa of the Valley of the Wind and Castle in the Sky, Kaina tells the story of two worlds - above and below, both of which look to one another for salvation. Part of coming-of-age, part adventure, part high fantasy, this is bound to be a classic. Nihei's character designs are brought to vivid and engaging life by Itoe Takemoto (known for series including The Beast Player). With a very well-received anime adaptation currently on Crunchyroll, Kaina of the Great Snow Sea is perfectly set up to be a smash hit. 
A young man named Kaina ekes out an existence high atop the canopy that spreads from the titanic orbital spire trees. He and the handful of aging fellow villagers who remain believe they are the last humans in the world--after all, no one could survive amid the great snow sea that blankets the surface below. But they're about to learn how wrong they are... 
Here begins the epic tale that could change the fate of a dying world forever!
