The year is Future Century 60; much of mankind now lives in colonies surrounding the earth. After being ravaged by countless wars, every four years the dominance over the colonies is decided in a martial arts tournament called the Gundam Fight. This year marks the 13th tournament, and Gundam Fighters representing their colonies have begun to gather. Their purpose is to fight, and fight, until only one remains to claim the title “Gundam of Gundams.” But Domon Kasshu, Neo Japan’s representative, has another secret mission; and should he fail, all of mankind may pay the price. Gundam Fight! Ready! Go!
