A young boy named Tsutomu, is failing in school from his obsession to Ultraman Gaia. One day, while watching an Ultraman Gaia episode, he gets teleported into hyperspace where he sees a girl and behind her a scene of mass destruction. He later sees that same girl, named Lisa, in his class. Later on, he finds a mysterious glowing ball (Also from the dream) that tells him it can make any wish come true. The one thing Tsutomu wants more than anything else is to meet Gamu, Ultraman Gaia's human host. After his wish is granted, Gamu actually appears, but a bully takes the ball and makes the second wish; for a monster, Satan-biezor, to fight Gamu.
