Tetsu Daito and his apprentice Naoto Kiba operate a karate dojo. In order to keep the dojo afloat, they pull in extra cash through their company, God Hand, through which Kiba hires himself out as a bodyguard.

Despite his master's claims that the assignments won't be dangerous, somehow Kiba is constantly in danger. Kiba eventually agrees to protect a beautiful woman in Hong Kong, thinking the job will be an easy one. But he was wrong. Dead wrong.
