When the weekend comes, skilled drivers gather. Amidst the roar of engines and the cheers of the crowd, hot battles are fought with pride on the line.

Furthermore, the female-centric team "ROSE VEIL," combining elegance and skill. Beautiful, and faster than anyone else. Encounters with them will change not only the matches but the course of love itself.
