Output: In a change from previous Ultraman movies, this takes place in another universe, in which Ultraman Gaia is just a popular kids TV show. A young boy named Tsutomu Niiboshi, 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 Nanase, 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 Takayama, Ultraman Gaias human host. After his wish is granted, Gamu actually appears, but a bully takes the ball and makes the second wish; for a monster, SatanBizarre, to fight Gamu. After a Gamu transforms into Ultraman Gaia, he finds he is losing power quickly, but manages to defeat the monster regardless. Afterwards, reverting into Gamu, he is chased by kids through the neighborhood until he finally manages to elude them by hiding in a toy shop. Once inside though, Tsutomu and his friends find Gamu and Tsutomu explains to Gamu just how he was brought to their world. Tsutomu tries hiding Gamu in an abandoned hanger, and during this time, Gamu sees that Tsutomu has a present for Lisa, a book called Gullivers Travels, which was a favorite of Gamus as a child. While scanning the ball for the answers, not only do the police find him, but Gamu suddenly finds himself back in his own world, and accidentally takes the book with him. He is soon able to recall the events and checks the data he scanned from the ball, and gets a vision telling him that Tsutomus world will soon be destroyed. Unfortunately, during the whole ordeal, Tsutomu loses the ball, and the bully finds the wishing ball and wishes for a giant monster to appear. King of Mons is created and starts destroying their suburban Tokyo neighborhood. Gamu becomes determined to open a gateway between the two universes to stop the monster and save the world Tsutomu lives in. Gamu is soon able to find his way there with the aid of a new mecha, the Aventure, and transforms into Gaia to battle the giant monster. Soon, Gaia is in a deadly battle against the monster. The monster then spawns two more monsters that are equally as strong as the original, one whos specialty is in water and the other whos specialty is sky. Tsutomu, knowing that Gaia is in trouble, tries to wish for help only to be sent flying into the air by one of the monsters stray beams. Just as all seems lost he is rescued by Ultraman Tiga and Ultraman Dyna, who have come via The Light into the battle to help Gaia. The three Ultramen battle the monsters. Tiga and Dyna destroy King of Mons spawns. Gaia manages to oblitirate King of Mons with a highly powerful laser blast and saves the day. Gaia then turns back into Gamu and reveals Lisas secret to Tsutomu: She is the humaninterface of the ball. Even though Lisa will disappear forever, she urges Tsutomu to wish for the ball to vanish forever, repairing all of the damage that had been caused by it to that world. Before returning to his world, Gamu returns Tsutomus book to him and tells him Thanks to this book, we were able to meet again. At the end of the film, Tsutomu relives the day Lisa appeared in his class, but is unable to recall the events of this film. During the credits, though, as he shows Lisa the book, there is an autograph and a message to him from Gamu, as he sees the XIG Fighter EX flying through the air before disappearing.
