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. 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.

Kaina, Ririha, and Yaona descend into the bowels of the royal palace to prove the existence of the Great Orbital Spire Tree, but just as they find the evidence they're looking for, Valghia unleashes a monstrous weapon…
Can Kaina and his friends save Atland from destruction?!

The climactic final chapter in the tale of the young heroes striving to change the fate of their dying world!
