Both this and post #644416 are the only posts tagged with Princess Princess (Maika). Both were tagged as artist for Tsuki Kazui, which is uh... weird, because the VNDB page lists 4 different illustrators and none of them go by that name. This one at the very least is adapted from the cover art, so I'm assuming they're both official art and slapping them with an "artist request" instead for now.
