Fuuga is a golden furred Japanese Wolf, father of Retsuga, minion of Reima and one of his Eight Canine Warriors of Sirius, Suiga's teacher and he knows the Battouga.

Fuuga was once saved by Riki. The wolf had left the palace because he didn't believe that killing humans with their powers was right but some minions of Noroi, the Warriors' teacher, were sent after him and he was soon cornered. Riki appeared and saved Fuuga's life who, in return, taught the Akita the battouga and never forgot the dog and the two met other times, since Fuuga stayed 5 years away from home and once travelled to Ohu to see Riki and to warn him about Reima and Gaia searching for Gin. Smith tells him that Riki died and that Gin is after some wolves. Fuuga goes to help Gin and has to face his son, who doesn't recognize him and tried to kill him, under Noroi's orders, which makes Fuuga take the desperate decision to kill his own son. His old student, Suiga, stops the fight and tells that it was Noroi to kill Fuuga's mate and that Fuuga is Retsuga father. Fuuga joins Reima once again and befrends Gin but accused Noroi of betrayal. He goes with Gin's pack to fight Gaia and saved the Akita from Juga. The two wolves fight and Fuuga says that there can be only one Zetsu (Batouga) Warrior at time.

Fuuga then, lets Juga kill him.
