By 2048, motor racing has evolved into a popular fighting race called IGPX, a competition of humanoid high-speed mechs running at 600 km/h. As the winner of the IG-2, Team Satomi is now joining the top league, the IG-1. But on the other side of the shining glory, the young team suffers for a total lack of teamwork.

And when Takeshi meets with Yamma, from the next opponent, Team Sledgemama, he gets a harsh greeting. Will Team Satomi make it in the IG-1?
