A living human-paopei (divine superweapon) hybrid, he has once been dead and revived with the aid of Taiitsu built via lotus plant. Possessing little emotion and a cold personality (although he does have a bit of a soft spot for his mother and Tensyou whom he watches over after Tenka died), he exists largely to fight and is more "directed" by Taikoubou than lead, albeit at times that became hazardous to Taikoubou's health as Nataku has no qualms about shooting his weapons at people. He can fly thanks to his special boots which have a metal wheel under each one. His weapons are his iron bracelets which work as homing missiles and hit the target with tremendous impact. Throughout the manga Nataku gets several "up grades", namely from Taiitsu who gives him new weapons. Nataku has a serious grudge against his father who was responsible for destroying the grave his mother made for him when he died.
