The eldest son of the Daimaru Clan. He desires to bring the Kyousen Style out of the shadows and to dominate all other schools. To fulfill this plan, Ryugo has sought to 'perfect' Sakon's genius by subjecting him to mental and emotional trauma, thus creating the perfect warrior. Gama later pointed out that Ryugo's actions actually ruined Sakon's true potential, by turning him into nothing more than a 'mindless beast'. Ironically, he is killed by Sakon, who shatters Ryugo's spine while in his berserk state.
