Animation is great
It was a pretty weird thing to watch, but you made up for it for just being so cool. I didn't even know that was part of the entire song (meaning I thought they were separate songs). It just helps that the animation is so slick and everything fits together well. That one guy with the sharp teeth reminded me of Suigetsu from "Naruto". I especially like how the main character is just such a positive and likeable character. You only see him for about three minutes, but you get a great impression of him.
