Takeshi Yoshioka's sole appearance was within Tsutomu's own cassette tape of an Ultraman Gaia episode, wherein he portrays his character Gamu and Satanbizor's own disguise. Through the Red Sphere's help, Tsutomu would bring the actual Gamu to his world, thus creating a series of events which lead to the movie's plot.
