Compile Heart released the new Gun Gun Pixies pre-order gift illustrations in Japan. Well, not “totally new”, Compile Heart already released them before but only the drawn version.
These new ones are the final versions, with the colored finished illustrations from the Imagine / Imagine WEB, ebten, Sofmap, Yahoo! Game Store and more.
The exactly store list can be found in here (and you can find the pictures in the gallery): http://compileheart.com/ggp/info/?page=2
