I remember listening to this while I was studying for my A levels and now I am listening to it while I am working on my B.A thesis. :D Thanks for uploading this, and thanks to Hiroyuki Sawano for being a genius.
I just watched ao no exorcist season 2 episode 6, and while this was playing I thought my ygo pro app was still on, but wow, the music is actually from this show
I like the first season when Rin unleashed his true form before Mephisto. Now I want the soundtrack when Rin encounter Lucifer for the first time. It was intense. Sorry for being an Audiophile
