Aoi Nanase did this? Really? Pretty cool because this girl will be in the upcoming game: Luminous Arc 2 Will for the Nintendo DS.
Don't believe me? Check their official site:
http://www.mmv.co.jp/special/game/ds/Luminous2/
and browse through the character section. You'll find the girl that looks almost...if not completely identical to
this image.
Be aware that the site is in Japanese.....but it isn't that hard to look for this girl if you follow my word.
By the way.....maybe I should request a Luminous Arc Gallery. The girls are very cute / beautiful / adorable.
