Being a fan of the good old hack n' slash anime ninja movies, I had to check this title out. I wasn't really expecting, much I didn't really get all that much either.
Story- Okay so the story is about this guy named Jiro and he is framed for killing his own parents. Well except he did kill his own father, but he didn't realize it was his father. So he vows to take revenge on the one responsible, a monk looking dude by the name of Tenkai. So theres Iga and Koga ninja clans in this (surprise surprise) and they're duking it out and what not, but our boy Jiro is a lone ninja and he has a special dagger (guess what its called) It was made in a foreign land and has foreign script on it and he wants to find out the mystery. This is where the story kind of gets strange. So Tenkai is contantly sending ninjas after him and and he has to fight them off and at one point he meets this black slave that helps him get on this ship that takes him to Russia... yeah I'll let you find out the rest by yourself lol.
Animation- The character designs look a bit too plain for my tastes... and kind of blocky at times, but they're still not bad. The animation is fairly good for its time. Some interesting animation techniques were used and I think this might be one of the first anime to use the whole "sparking/glowing" blood thing... it actually doesn't look too bad.
Sound- The usual fare for this kind of movie, classic Japanese sounding stuff. The ed theme was kind of really sad though. Also when the ninjas attacked people they would make this really annoying sound...
Characters- Jiro is a pretty decent char and hes got the whole tortured past thing too. Tenkai is your basic really evil Antagonist with no redeeming factors. All the side characters are a bit like stereotypes... there is kind of a twist with two of them though, wihch was somewhat interesting.
Overall- If your a fan of ninja anime movies, that always seem to have the whole Koga v.s Iga thing then you should check thing out. Since its so old I'm guessing most movies of this genre drew inspiration from it in some form. I'm talking about stuff like Wrath of the Ninja, Ninja Ressurection, Ninja scroll, Blood Reign: Curse of the Yoma. So if you enjoyed any of those, I would say this is worth giving a shot.
