Tomoe Shiro, a formidable racer with a very promising career, makes a sharp turn when a serious accident puts his life at stake. He recovers miraculously, though, when his heart is replaced with the engine of his own racing car. However, for that very reason, race regulations demote him to the status of a mere mechanical part of the vehicle, depriving him of the right to participate as a pilot in regular races. Only on a faraway colonial planet, alongside a multitude of other charismatic pilots also barred from participating in regular competitions, will he be given the opportunity to race for his pride and the prize money. And so this exciting rally begins!!
