Ryu was born in the House of Hayabusa which is a branch of the Dragon Clan. Once before, Ryu was engaged in a fierce batter with Jaquio over the statues of the evil demon, and was able to come out the victor only after a very difficult battle. Ryu is known as the "Ninja Dragon" and he is in possession of the secret "Dragon Sword." When he is not fighting evil, Ryu runs a shop with Japanese antiques, together with his girlfriend Irene.
