Chihiro grows up in the mountains with his father, Kunishige Rokuhira, a celebrated swordsmith who forged six enchanted blades that won Japan the Seitei War. The serious boy trains under his easygoing father and hopes to follow in his footsteps. Then a band of powerful sorcerers murders Kunishige and takes the sacred swords. Three years later, Chihiro wields the Enten, a seventh blade his father made in secret, and hunts down villains tied to the Hishaku, the group he holds responsible. Though his skill and the sword's power are still incomplete, he is set on recovering the stolen katanas and avenging his father in this action fantasy drama.
