Finally posting about this song here. I don't know why I haven't earlier, but here it is, the famous theme song of the Black Rock shooter, originally composed by Supercell group and sung by Hatsune Miku. It was created by the inspiration of the illustration done by Huke.
This is also the ending song of both OVA and anime series and it goes quite well with these I must say.
~ Enjoy!^^
