However, a racing circuit known as MFG, which employs traditional internal combustion cars, is garnering popularity worldwide.

Takumi Fujiwara, the legendary downhill and rally racer, turns out to be Kanata's trainer. MFG employees who are familiar with Fujiwara and former racers from the same generation begin to notice Kanata. A new whirlwind is about to set off at MFG.
