This was one of the films I watched as psychophysical research for Domo ArigaDIE!!! It was an act of sharpening the senses, heightening the way ninja magic actually flows. I don’t know how much of the actual story of this film actually seeped into the novella, but it’s butt-kicking ninja action glory certainly did. This is an essential film for serious ninja fans. You already knew that, though, right? Enjoy the trailer.
