A man gave his soul to the devil in order to bring hell on earth, but he has to wait 10 years to finish the pact. While doing this he fights a great Nimpo fighter and he defeated the nimpo fighter, 10 years later when the world is about to be overcome with demons.. the fighter had a son. His son knows some about nimpo, but still needs to be trained more, when a short man projects his image to him telling him that he is the only one that can save the world.. he doesn't see why he should waste his life and time on it. Then a woman asks him to help, but he still refuses.. until she says she will go on and do it herself. Being the gentlemen he is, he helps her through the city, defeats many demons, gains a few friends, then basically he ends up fighting the man who sold his soul.. I won't give away the ending of course =P
