Kenkajima is an island that is not marked on maps even though it is in Japanese territory. There lived a family that possessed a phantom martial art, an invincible fighting technique.

Catcher Kao , who was born as the fifth-generation successor of the Invincible Fighting and Taijutsu Dojo , wore a super training suit from an early age and devoted himself to special training. Starting with a martial arts match, he travels to Japan. In order to become the strongest man in the world, he begins a battle with other schools for the honor and prestige of Total Fighter Khao's dojo.
