The year FC (Future Century) 60 has begun, and the Gundam Fight has begun anew. After the elites of each of Earth\'s nations fled the polluted planet, creating luxurious space colonies from which they could control the wretched masses they\'d left behind, they soon found themselves at war with each other. To resolve the conflict, it was decided that leadership would be rotated among the space colonies. Every four years, a tournament is held to determine which colony will be the temporary master of the world. This tournament is the Gundam Fight. Each space colony selects a champion to be its Gundam Fighter, and constructs a giant combat machine called a mobile fighter for its national representative to take into battle. Representing Neo Japan, Neo America, Neo China and a hundred other nations, the Gundam Fighters meet in martial combat to fight, and fight, and fight until only one remains. And, of course... Earth is the ring! But this time, in the 13th Gundam Fight, other forces are at play. An experiment has gone awry, and a nanotechnological monster of unspeakable power has been loosed. When Neo Japanese Gundam Fighter Domon Kasshu falls to Earth, he has more on his mind than just winning the tournament; he must find the Devil Gundam, created by his father and stolen by his brother, before a catastrophe befalls the world that will dwarf anything ever before imagined...
