The story is really formulaic, just like Hokuto no Ken. Guy has his loved woman (sister in this case) taken by someone. He goes around looking for her. He finds people being robbed/raped/killed by gangsters. He beats up/kills these gangsters. Big boss appears. He beats the big boss. Repeat ad infinitum. You get the idea.
The art is really good though. The art style is really polished and looks cleaner than the original. Character designs are great, not affected by the manface problem which plagued the original.
