The year is Post Disaster 323. Mars has been successfully terraformed and colonized by humans more than 300 years following a catastrophic conflict between Earth and Mars known as the "Calamity War." Despite technological breakthroughs, individuals on Mars yearn for independence from Earth's authority and aspire to enhance their standard of living. Furthermore, while most of Mars' states have gained autonomy, the planet's economic progress is mostly dependent on Earth. Mikazuki Augus, a young orphan, is part of a group of children who serve for the civilian security firm Chryse Guard Security, which has been entrusted with the safety of the Martian Princess Kudelia Aina Bernstein, who has aspirations for her nation of Chryse to gain independence from Earth. The gang was attacked one day by the Earth Military organization Gjallarhorn, which intends to put an end to the Martian independence movement. During the battle, Orga Itsuka, the head of the children and the Third Army Division under CGS, decides to rebel against the adults and higher-ups who have fled, leaving the children and foot troops to fight as decoys. As he falls inside the renowned mobile suit, the Gundam Barbatos, Augus must now choose between his buddies and his objective.
