Sekiguchi (19 years old), a virgin going bad, is in love with Midori, a motorcycle rider and a very hot girl! Despite having no license, no bike, and no knowledge, he turns into a gung-ho man and forcibly joins Green Hill, the bike team to which Midori belongs. However, there is a rich NEET with chest hair, a violent hard-core dude, and a guy who looks just like Itokin from Boku to Issho (?!)... It was a sanctuary where fierce, beast-like blockheads lived out their love of motorcycles!
