It’s a world where a magical tree grows from the back of a swordsman, a mute girl is turned into a living weapon by her mother, a frost dragon roams the skies seeking vengeance, and beings with godlike powers clash for the balance of nature. In the middle of it all is Bira, an orphaned boy, happily spending his days fishing inside a secluded forest. Then he meets Tanyu, a former general on a quest to find his childhood love. Together, they journey into an enchanted landscape unlike any other.
