Kazu Tenjisei was 19 when he became a Dairanger. A confident striking hair-salon stylist always impeccably dressed, groomed, moving, the supposedly cool city boy was actually a country boy. He ran away from his native town when he was fifteen years old. A little old lady selling ramen from her street-stall noted this fragile boy staring longingly and very lost nearby and took pity on him. If it hadn't been for her he would probably have returned home. But Kazu turned himself into a cultured city-boy. He was a great dancer, as he had mastered the Drunken Fist fighting style and odd though as it may seem, he had a tendency to go rushing into battle when perhaps he should have thought it through.

In episode 12, he faced the Immortal Tofu in a drinking contest. But his teammates had made certain that his drink was clean. In episode 25, his photograph was taken by the Copy Empress Gorma, who then produced his evil twin. However good the copy was, it was still flawed and when it faced the real Kazu alone, it was destroyed.
