Born a brindle ("Tora-ge" or tiger-striped) Akita, Gin ("Silver", named for his coat) is destined to become a successful bear-hunting dog. However, after witnessing his father's death at the hands of the man-eating demon bear Akakabuto, he is chosen over his siblings to succeed his father and defeat the monstrous bear terrorizing his home village. As Akakabuto gathers his own allies, Gin must travel across Japan to find dogs to join him in an all-out war of dog versus bear.
