The show is set roughly 300 years after a great conflict between Earth and Mars known as the "Calamity War." A woman named Cordelia sets out on a journey to Earth to speak for the independence of the Martian city of Chryse, which is under the control of the Earth government. Escorting her is the private security company Chryse Guard Security (CGS), of which protagonists Mikazuki Augus and Orga Itsuka are members. When a group named Gjallarhorn attacks CGS and Cordelia, Orga sees this as a chance to rebel against CGS and launch a coup. Mikazuki and Orga are thrust into a new conflict. To fend off Gjallarhorn, Mikazuki rides the Gundam Barbatos, an old mobile suit powered by a nuclear reactor from the Calamity War.
The official website also revealed new visuals for protagonists Mikazuki Augus and Orga Itsuka, as well as other characters and mobile suits appearing in the show.
