In all seriousness a setting like this were the girls are super hot yet underfucked is ideal for NTR enjoyers. It's all too easy to craft a scenario where a sexy nikke gets forced or coerced into having sex with some playboy with a monster cock. Helm didn't get several NTR doujins because just because she was popular. She got them because her circumstances were dangerously close to an NTR plot to begin with. SKK being the only real candidate for sex doesn't help matters either. Who's to say another rookie commander or repair center technician can't turn up the charm in our absence? 99% of nikkes can't fight back against ark citizens. Rupee was literally going to be abducted and raped in that screenshot posted earlier. All of the girls wearing slutty bunny costumes are walking around a casino getting ogled by horny men. It's way too easy to slide NTR into the events the game gives us already.
To give a TLDR, Nikke's setting is absurdly compatible with NTR. It takes very little effort to write "believable" scenarios that end with nikkes getting fucked by different men. You'll have to deal with it until EOS, for better or worse.
