During the WGP's Royal Festival Cup, an unknown machine called the "Gun Bluster XTO" and its owner Rion Cusco appears racing without control and causing various riots with fellow racers. This makes Go's Cyclone Magnum reach the goal but a dissatisfied Go and the TRF Victorys decides to pursuit the situation. This was all due to the Gun Bluster's special GP Chip invented by Professor Cusco gone haywire while emitting strange EM waves, making the machine a powerful weapon. To avoid further destruction to the city, Professor Cusco decides to destroy the machine before a rival association acquires it. It's up for the TRF Victorys and Rion race together and safely halt the Gun Bluster before its too late!
