Li Xiao, a scout who was permanently banned by the league, returned to the world after five years of dormancy because he took a look at Yu Jin, a good-for-nothing player who was despised by the entire league. No one believed that Yu Jin could play ball, but Li Xiao decided to risk all his reputation and lead him into the underground game known as the "Crazy League" - there are no rules here, only blood and madness. When Yu Jin used his incomplete skills to tear away all doubts, Li Xiao's eyes of revenge slowly opened: this league was originally a training ground for the two of them.
