The central plot revolves around Bunshichi Tanba, a dojo-crasher who seeks out stronger fighters to prove his strength to himself. While traveling to several schools and challenging the best each had to offer, Tanba arrives at the FAW (a gym that trains pro-wrestlers) and is pitted against T. Kajiwara. Tanba is defeated and humiliated after realizing that he is not strong enough, and he disappears for 3 years. Upon his return, he has become nearly unbeatable.
