Around Lake Okutama, where sharp curves continue endlessly, riders who are confident in their arms are straddling the proud monster machine. When I found such riders, there was a boy who challenged a street race betting a machine. This boy, who was feared to be the phantom 50cc rider of Okutama, who won all the races, is the unconventional genius rider, Makoto Kamikaze. One day, Makoto was challenged by a mysterious duo of riders, the bullet brothers, to play a motorcycle. The match venue is Okutama Amusement Park at midnight. The bullet brothers have designated Japan's largest roller coaster "Corkscrew Monster" as a circuit !! How will Makoto capture the monster coaster with a maximum ground clearance of 120 meters !?
