Fighting expert Bunshichi Tanba enjoys defeating TV fighting champions and celebrities on the street until he stumbles into the underground wrestling club known as FAW (Federation of Amateur Wrestling). Unfortunately, there he's defeated by a wrestling world underdog and forces himself to improve before seeks his rematch. Years later he returns better than ever and his fights attract the attention of the two "monsters" of the fighting world that are constantly in competition with each other, Makoto "the great" Tatsumi, owner of the FAW and with a power and charisma unrivaled in the ring, and "the demon of karate" Matsuo Shozan, owner of the best Karate schools in Japan and with a power and speed that's almost godlike.
