It may come as a surprise, but big tiddy loli isn't exactly top seller when it comes to aesthetics, not many found her appealing to bust a nut for, the crowd for that kink is relatively scarce. Not to mention she was comically evil by the way she represented herself, the reception she got, had nothing to do with the skin tone, people loved that part for being literally the first girl with that appeal point for JSK heroines, had JSK based the new heroine for Kakudate Karin instead of Ichinose Asuna from Blue Archive, the sales wouldn't taken negative blow due to it, in fact, might even had boosted those, as those two are quite popular gals as far as I am aware.
But that's just my two cents on the matter, take it however you like.
