Yet when he witnesses his father"s death at the claws of the man‑eating demon bear Akakabuto, he is selected over his brothers to inherit his father"s mantle and vanquish the beast that terrorizes their village. While Akakabuto amasses allies, Gin journeys across Japan to recruit dogs for a dog‑vs‑bear conflict to protect the people and restore peace to their homeland and honor their legacy.
