I really like the film, I also liked when he was finally captured and they were transporting him back to the Ninja clan compound. He was healing himself from his wounds with his finger formations in his hands. Very Sho Kasugi-like. No doubt he contributed that little that detail to the film. Its also something addressed in my own training, ofcourse its exaggerated in the film but now I can appreciate better what those hand formations are all about. Back in the early 80's watching Kasugi's films, I didnt have a clue.
