One of the "Eradicators", he uses the Fiend Sword "Birai" (Lightning Tail) that was forged from the tail spike of a Black Dragon. Carrying the blood of his father "Raioh", a high-ranking demon, it is said that he's already as skilled as his father. But, probably because he had absurd amounts of strength since he was young, his personality is warped as he takes pleasure from seeing others suffer. After he and his father's invasion of Dragon Empire failed (owing in part to his own overconfidence), he was arrested. Almost executed on the spot for being a dangerous criminal, his talents were noticed and was instead invited escorted into the Empire. He doesn't care if he cuts someone down and kills them. For someone like him, it might mean the Empire is his ideal environment.
