"My name is Gen Kurosu, and as long as I stand, the Victory Flag will never fly over the heads of the Red Army! The machines roar and blood sprays! My name is Gen Kurosu!" Motocross is a sport in which contestants race for fame on steel horses through rugged, rough terrain. The essence of motocross is the struggle against the harsh nature and oneself. This is the story of a lone warrior who, despite being called "Stupid Don Quixote," stands in the way of the "Red Army," the most powerful motocross team in Japan, which has achieved an undefeated record of 150 victories in a single year. This is the memorable first serial publication of manga master Tetsuo Hara!
