I got the impression that it was leaning into raceplay as we started to move away from Sera's plotline but I don't really mind since raceplay can be really hot and this is mostly leaning into fictional raceplay rather than black vs white (at least at first until the Odette scenes which were rather blatant). I mean, you just have to look at the cult and how their stated goal is all "spreading demon seed". There's no subtlety to it, there's definitely raceplay on "demonkind corrupting poor humans".
So it's not too surprising. I do not want Nitrolith to lean too heavily into it, though, or at least if they do keep it to the fictional kind (demons vs humans, not black vs white). I'm here for the netori content. I've been following this game for quite along while during my first few times on this site so this kind of railshift would be a bit unwelcome.
Raceplay isn't what got me into this game, much less a totally not-BBC on blondes. Netori, corruption, and impregnation is great though.
