Shun's father. Gate Robo A mecha that uses a more compact version of the Gate Engine as its power source. Ukiya uses the Prototype Unit 00 Gate Robo, which is known for its extreme instability and unpredictability. Units 01, 02, and 03 are used by Jim Skylark, June Thunders, and Misao Sakimori respectively and amplifies their Gates even more. Aside from Ukiya, Reiko Asagiri has also operated Unit 00, and used its secret weapon, the "GRO5V" (see below), to activate her Gate of Illusions. Unit 00 was initially disabled by Reiji Kageyama's Shadow Robot at the battle atop the Tokyo Tower by smashing its Gate Engine, but Megane found an original prototype gate engine in the Ukiya garage, reviving it. This is the same engine that was used by Ukiya to eventually defeat Kageyama in front of live national TV. GRO5V The Gate Robo Unit 00's secret weapon, which is practically a giant piano. However, Ukiya does not know how to play the piano, so Reiko Asagiri uses it when operating the Gate Robo. Unlike the Gate Engine, this big machine requires lesser support personnel to transport it to and from the battlefield--it can just be dropped into the battlefield with a Vertol 3000. UP-15 It is a modified Toyota Sports 800 bearing the license plate AEGIS 01, powered by a Gate Engine, and is capable of using Shun Ukiya's Gate of Gales to reach incredible speeds. When it exits, the front of Tategami High erupts in a blinding sandstorm, which is a cover as the A.E.G.I.S. hangar doors open and the car exits. Ukiya even ran the car on tracks designed for a roller coaster in an effort to hurry to the scene of a battle. It is transportable to any location via a transport truck disguised as a tanker and is available on call within three minutes. It is referred to by Megane as the "Yota-hachi." As of Gate Keepers 21, it was the only working mecha remaining inside the ruins of A.E.G.I.S. Far East. After a brief hunt for Invaders, it was programmed by Ayane Isuzu to self-destruct (by overloading its Gate Engine) to destroy Kikai Shogun and his minions. BB5005 Electric Locomotive An electric locomotive loaned from A.E.G.I.S. France to help stop the runaway Shinkansen possessed by Kikai Shogun. It was the fastest locomotive in France, breaking speed records (at speeds in excess of 200 km/h).
