This one took a while.
And there are a lot of mistakes and things to improve on,
but, I'm still learning here... ; w;
The song is 'Counting Bodies Like Sheep to the Rhythm of the War Drums' by a Perfect Circle. Pretty badass song (not to mention terribly fitting) for this anime in my opinion.
I love how it came out though---I mean, look at Light! One of my favorite anime characters, and that evil grin of his is just too addictive.
