Fighting Spirit is about Ippo Makunocuhi's gentle spirit and lack of confidence make him an easy target for the bullies at his high school who regularly beat him up. Then, he's rescued from a beating by Takamura, a-larger-than-life professional boxer who inspires Ippo to learn the art of boxing.
After passing one of Takamura's outrageous tests, Ippo attempts to join the Kamogawa Boxing Club, but Chief Kamogawa refuses to believe Ippo has a fighter's spirit and requires Ippo to spar with Miyata, an extraordinarily talented and skilled boxer. Can Ippo even survive the first round?!.
