Had potential, but didn't go well... read Ranma½ instead. Similar themes, but done better.

One of the best martial art manga from mangaka tatsuya hiruta sensei ,
too bad no one try to complete translating the manga,
tbh the story is getting better at vol 30 to 59.
and the artstyle also getting better.
