Greatest Ninja Battle Ever Put on Film!

Greatest Ninja Battle Ever Put on Film!:

This is quite possibly the greatest ninja fight sequence ever put on film! It's ridiculously awesome in every way imaginable. I have no idea what movie this is from so please hit us up if you know! I want to watch the whole thing! My favorite part has to be the flamethrower sai! Hope you enjoy this ultimate ninja battle of death!
