Riki (Ginga Nagareboshi Gin)

Riki is Gin's charismatic father. He was believed killed in the beginning of the series by Akakabuto when he threw Riki off a cliff, but survived and had amnesia, becoming the leader of a pack of wild dogs. He was killed in the final battle by Akakabuto, when the bear slashed him open with his claws, but not before regaining his memories. In the manga it is revealed that he learned the Zetsu Tenrou Battouga from a wolf Hakkenshi (八犬士 Eight Canine Warriors?) named Fuuga, and upon his death, warns Gin never to use it again, because he fears the wolves will come after him.
