I'm looking into it now (I want the pic of the server twins). In the meantime, I found MCC has an anime OVA and the artist who does that is Kuroda Kazuya, the man known for doing the animation for "Spice and Wolf." I'm not sure if I'm allowed to link youtube here, but a quick google search brought up this English subbed version of the anime.

I don't think Kazuya also does the game illustrations. It just strikes me as a very different art style he just adapted to for the animation.
Edit: I give up. Couldn't find them on Pixiv or various other image boards, so your best bet may be extracting them afterall. I understand Ambition hires different artists for their games, but it would be nice if they did list the artist's name. I guess the artist prefers privacy, which I find understandable though dissapointing.
