Ryuubi (Fake)

In Shin Koihime Musō, it is revealed that he stole the name Ryūbi Gentoku from a girl (the real Ryūbi Gentoku) along with her sword prior to his appearance in the first series. He then became the target of the said girl, who intended to retrieve her sword and clear her name. He is later found to have lost the sword due to raids on bandit hideouts and his current whereabouts are unknown.
