Post Disaster 323. After a big war between Earth and Mars, called the "Calamity War," which lasted more than 300 years, Mars has been successfully changed into a habitable environment and colonized by humans. But even though technology has improved, the people on Mars still want to be free from the government on Earth and improve their lives. Even though most of Mars' nations are independent, the planet's economy is almost entirely dependent on Earth. Mikazuki Augus, a young orphan, is part of a group of children who work for the civilian security company Chryse Guard Security. Their job is to protect the Martian Princess Kudelia Aina Bernstein, who wants her country, Chryse, to become independent from Earth. One day, the group was attacked by the Earth Military group Gjallarhorn, which wants to stop the Martian independence movement. During the attack, Orga Itsuka, who is in charge of the children and the Third Army Division of CGS, decides to rebel against the adults and higher-ups who had fled and left the children and foot soldiers to fight as decoys. Augus must now decide whether to follow his friends or his mission when he stumbles upon the legendary mobile suit, the Gundam Barbatos.
