I was expecting something like this to be longer. It's hard to do so much with something that's basically a trailer. I'm glad it turned out to be awesome. I couldn't really identify any characters, because I didn't need to. This was awesome in every sense on its own. It's nothing but wonderful fight scenes.
It kind of reminded me of "Ghost In The Shell". I especially loved the colors. It wasn't too blue. My favorite character was probably the tailed monster thing. I'm impressed you can do so much with such a short music video.
