I remember when Blue Exorcist first came out and I heard the first 15 seconds of this song. I immediately put it into my playlist <3. It's very modern/techno sounding, and I really enjoy it, and I hope you guys do too!
I know, right?! I've had it as a favorite on my iPod forever it feels like. It doesn't grow old for me. What's weird is for some reason when my pod is on shuffle, tokyo ghoul songs and aoi exorcist songs always play one after another. It's creepy, but awesome. XD
