Given how much this character appears in Sugina_Miki's new art, I wouldn't be surprised if this was the main heroine for a new game.

I think it's just Innocent Grey's mascot character or something like that. It would be nice if she did appear in one of their games as a main heroine.

I can't say I've seen any other images of this character in Innocent Grey's earlier works, such as cartagra or "Eisai Kyoku." If this character was indeed innocent_grey's mascot, then wouldn't we see more pictures throughout the earlier works?

She has only recently appeared. In fact, I believe she just appeared this year. Here's her profile. http://www.gungnir.co.jp/innocentgrey/yomiko/prof/index.html
