This is the bonus faceplate sticker that CyberFront is including for those who pre-order Akatsuki no Amaneka to Aoi Kyojin, in Japan which hits on March 11.
It maybe just a sticker on the front, but just noting where it actually is.
The PSP stickers aren’t quite as offensive. Xbox 360 owners get a naughty faceplate of Amaneka Machbuster, the gameâ€™s protagonist. PSP owners get a less scandalous sticker sheet with Amaneka Machbuster fully dressed. Interesting!
