Ryuu-ou is the Bushinshou of the West, also the new King of the Ryuu clan. He is energetic and easy-going person. Unlike other members of Yasha-ou and Ashura's group he doesn't have personal score to settle with Taishaku-ten. However he joined the group, because it seemed to be fun adventure and he wanted to have some combat practice.
He died in volume 9 of the manga. Ryuu-ou went after Ashura who ran off to chase his mother, however in the end Ryuu-ou is killed by the "real Ashura", Ashura’s other side who is the god of destruction who wants to destroy everything. Ryuu-ou apologized to Ashura saying he can no longer keep his promise of protecting Ashura.
