- About Gamu Takayama played in Ultraman Gaia, although the setting of "Genius boy" was exactly opposite to himself, it was also a setting to have a fighting spirit that actively moves even if he fails, so from that point. It was easy for acting. He played as Gamu again in Superior Ultraman 8 Brothers, but since the work Gaia is a setting called Parallel World, he is considering both works separately, and on the extension of the TV series. He said he wants to play his dream.
