Parody?
At first I was thinking this was about Naruto because I just associate the term "Shinobi" with that. I also thought the guy was based off of Kakashi, but it was apparently a different thing altogether. But I digress. I was impressed by the animation, especially when he was jumping and slicing at the angle taken from the front. I'm not familiar with the source material, but this didn't strike me as being that much of a parody. In fact, I think you're better off just doing action animations.
