History of Space Migration and Space Wars - After the end of the Universal Century, time flies and people usher in a new history, the Regild Century (RC), and begin a prosperous and peaceful life. In RC1014, the Capital Tower, an orbital ladder that connects the earth and the universe, brings Photon Batteries, the source of energy for the earth, from the universe to humans, so it is regarded as a holy place. During his first flight, Bellely Jenum, a candidate for the Capital Guard, was attacked by an unknown MSG-SELF. Bellely used a maintenance and inspection MS to fight it and successfully captured it. However, Bellely had some feelings for the space pirate girl named アイーダ・レイハントン, the pilot of G-SELF. G-SELF, which will not start unless certain conditions are met, had some reaction to Bellely. The purpose of the space pirates and Airda, the fate of Belllee who was chosen by G-SELF, the truth that shook the entire RC - all this is just the beginning of Reconguista.
