In the spirit dimension, the spirit of Kyuuemon Shingetsu Kibaoni was at peace. After aiding the Ninningers as Midoninger, and fighting them earlier, he decided to rest. However, something was still bothering him. Since most of the Youkai were revived, including Ariake No Kata and Mangetsu Kibaoni, there would be even more evil. Suddenly, Kyuuemon noticed a dark cloud of evil rising up from the spirit world, thanks to a lot of fear from previous attacks. It left the spirit dimension and entered the mortal world. It was Gengetsu Kibaoni, who had revived for some reason.
Meanwhile, in a spaceship, a figure wearing a suit was on a stage. He looked strikingly similar to Baron Nero of the Shadow Line, but with a different face. His name was Cosmo Royale, the host of Galaxy Warriors, a popular game show. The game show involved gladiatorial matches between aliens from different galaxies, but it was a front for the "champion" of the show, Galvanax. Robotic flies with cameras attached to them scouted the area for a good place for the next show. Galvanax was using the show to seek ninja Power Stars, which were taken by five teenagers. Galvanax's warriors were sent one by one, as contestants, to retrieve the Power Stars. However, this time was different. Galvanax was fascinated with a black cloud appearing on the streets, and that was when he saw someone emerge from the cloud: someone who looked EXACTLY like himself. Galvanax sent one of his soldiers, Ripcon, to investigate.
Later, on Earth, in Japan, Ripcon approached Galvanax's lookalike. He was speaking Japanese, but since Galaxy Warriors was an intergalactic show, the staff supposedly had translation devices to translate most languages. Galvanax's lookalike kept talking about someone named "Gabi Raizo" as soon as he saw Ripcon. However, both of them were beamed on the Galaxy Warriors ship.
On the ship, before Galvanax appeared, Cosmo Royale was announcing the latest competitor: an armoured ninja wearing light grey. He was introduced as a guy whom they just found, fighting another ninja who looked like him, except in black armour. Galvanax said to Cosmo, "What is the meaning of this? I found someone who looks exactly like myself!" Cosmo Royale said "I have no idea what you mean!" Then Galvanax's lookalike said "What am I doing here? Do you have any idea who I am?" Galvanax said "I don't know who you are, but this is my ship!" Then the lookalike said "It looks like you have no idea who I am. I am the warlord, Kibaoni Gengetsu!"
