Kazu didn't have his own feature episode until 12, wherein he faced a tofu-Gohma in a drinking contest. But his teammates had made certain his drink was clean. He didn't have another feature episode until 25, wherein his photograph was taken by the copy-machine-Gohma, who then produced his evil twin. However good the copy was, it was still flawed, and when it faced the real Kazu alone, was destroyed. (note: the actors are identical twins, which made the duo scenes so much easier to shoot, don't you agree?) During the episodes 28-31 arc, he became friends with Kameo, who was the only person to learn Kazu's secret: namely that he was a country-boy. The two became fast friends, and in episode 31, when we discovered a secret even Kameo didn't know about himself, we also watched Kazu captured and tormented, nearly to death, by a powerful set of evil Gohma. Kazu managed the rest of the series without being the absolute focus of any attacks. He was always there for his group.
