The year is UC 0153. The conflict between the Earth Federation and Zeon is long over, and the majority of humanity has migrated to the space colonies. Even the Federation headquarters has been moved into space. Only a handful of humans still live on the planet. The Earth Federation has weakened, allowing the space-born Zanscare Empire to gain power. The fanatically religious Zanscare begins to conquer Earth, and the weak Federation is unable and even unwilling to do anything about it. Only the League Militaire, a resistance group mostly made up of the remaining Earthnoids, and its newest weapon - the Victory Gundam - stand in the way of the Zanscare Empire. Uso Ewin, a 13-year old boy, takes the controls of the Victory Gundam in this series, making him the youngest hero in any Gundam series to date.
