As a claymore fan, i just have to share this. The song is not so new, but it should really be used in Claymore anime, not to even mention it's a song from Gackt-sama.
Everything about this song is so great, even the video contains lots of inspiration. I've been watching is like 30 times now and i plan to create some photos out of the inspirations i've got. Feel so excited already =")
Hope you like it as much as i do.
