Hoshin Engi 7

"When his clan is wiped out by a beautiful demon, young Taikobo finds himself in charge of the mysterious Hoshin Project. Its mission: find all immortals living in the human world and seal them away forever. But who do you trust--and whose side are you really on--when you've been trained to hunt demons by a demon.

When the land of Seiki declares its independence, Bunchu decides to destroy the fledgling kingdom. Taikobo attempts to mount a defense against this powerful enemy, but when the Dashiben, his only weapon, is stolen, he must rely on his wits alone.
