Orbus, a space pirate, once attacked the Earth with the intention of targeting Planet Energy, which served as the lifeforce for the planet. If he managed to attack multiple Release Points, which were the areas with concentrated Planet Energy, the Earth faced destruction. Takasugi Seiji, along with his girlfriend Kosaka Hikaru, took shelter in an old temple when the first attack transpired. Fortunately, Seiji was bestowed Orin, a token from the Earth guardians' leader, which enabled their patrol car to transform into the powerful Robot, Da Garn.
