Actually a pretty descriptive title the "Princess" is Sue Shiomi, Sonny Chiba's daughter, who he trains to take revenge on the men who crippled him. (Chiba himself is in this movie for all of fifteen minutes or so.) A bit choppy here and there, with some continuity errors, but it's hard to tell if that's in the original print (I saw a dubbed American release). Very loose plot turns into a variation of "your school is better than my school" and the inevitable martial arts tournament, although that's eventually dropped for just a big battle. Shiomi is attractive and seemingly a good actress, the fight choreography is mostly pretty good although there's a tendency to indulge in weirdo camera angles, and there's one great bad guy, a white-haired gentleman who's blind and goes nuts when loud noises hit. Fine of its kind.
