Reju was a ronin of the Flesh Dragons juzimai, led by Kitsure. The bandit gang terrified the village of Mimura since 1121. All the members bore tattoos covering their bodies, riding Otaku Steeds with Unicorn Clan markings on the saddles. The other members of the gang were Jimitsu and Kesu. Reju was loud and obnoxious, shouting obscenities during the attacks as a psychological strategy in combat.
