The Hakkenden: Legend of the Dog Warriors

During Japan's war-torn feudal era, the Awa clan faced certain extinction at the hands of a rival clan backed by demonic forces. But a careless promise by their lord brings both salvation and disgrace when the family dog returns with the enemy warlord's head and insists on marrying the lord's daughter. Their unnatural union bears fruit, but when the two are killed, the eight unborn pups are reincarnated as the eight Dog Warriors, the Hakkenden. Slowly they find one another and come together as a group. These eight warriors, who represent the eight separate aspects of Bushido, fight bloody battles against demonic entities and evil samurai in a final attempt to redeem their clan.
