^ You can find a few pics where the dark skinned girl is getting fucked by a futa on 23's pixiv, but you never actually see if that light skinned girl is the futa (at least I couldn't fin any with her face). But there was only one pic of her with some other girl, so she's the most likely to be said futa.
Too bad only Silva made it into Shadowverse. Would be nice if they made Song a card too, and adds some interaction between them. Katalina has one line with Vira.
Cool, I might have to check that out, at least a little bit. There was that girl in Classroom of the Elite that reminded me of a shy Nozomi, but she was just a side character, so not really a Nozomi spinoff so to speak hehe.
