Kouta Shimura endures bullying and humiliation at school because he cannot afford to lose focus on the part-time work that helps pay his mother's hospital bills. His life changes when a clumsy fight with his classmate Kanegon is accidentally streamed online and goes massively viral. For the first time, Kouta realizes that the same violence that made him a target of ridicule can also earn real money.

The two build a channel around Kouta fighting opponents who are larger, stronger, and far more experienced than he is. Then Kouta discovers a mysterious series of videos teaching exactly how an ordinary person can defeat different kinds of fighters. By studying every lesson and testing it in real confrontations, he begins climbing through the ruthless world of online fame, where one successful fight can change his life and one mistake can destroy it.
