Hajime no Ippo Filler List

Ippo Makunouchi is a timid, bullied high schooler who discovers his talent for boxing after being rescued by professional boxer Takamura, rising from a nervous novice to a determined featherweight contender.

Mamoru Takamura is a brash, supremely talented boxer at Kamogawa Boxing Gym who rescues Ippo from bullies and becomes his mentor, driven by an insatiable hunger for stronger opponents.

Genji Kamogawa is the gruff but deeply caring head coach of Kamogawa Boxing Gym, who trains Ippo and his gym-mates with hard-earned wisdom from his own boxing career.

Ichiro Miyata is a boxing prodigy and Ippo's fiercest rival, whose technical brilliance and rivalry with Ippo drives much of the series' early tension.
