My cutie mark would be アニメ. Which is the Japanese symbol for anime. I have a huge passion for anime and Manga and love just about everything about it. I have watched MANY animes and I only read Manga. (Unless I have to read something for school.)

I am a pretty big fan of nu-metal and groove metal. But I like groove metal better and I would have to say this is my favorite groove metal band.
