Set in a fantasy world based on ancient China, the story is about Fuuren, an armless Defender. Defenders are people who will complete their mission or assignments no matter what. If they accept them, that is. Fuuren has been called to a small town that is about to be taken over by the Ka empire, and they wish to hire him to help their armies defend their little town. However there is a little bit of intrigue within the town itself, and Fuuren accepts a different task altogether.
