I'm forced to have impression that the author aren't cutting corner on their wish fulfillment, flying car, women in skimpy japanese outfit carrying firearms.
We're desperate for idea!
there's onee-sama, but ane-ue is more of an old speak that actually fits their royalty status here.
so yeah it's hard to get it perfect here without it sounding unusual to readers that less deep into japanese culture
"ane-ue" is a bit awkward imo. I think big sis or older sister is fine.
aside from that, thanks for the translation 🫡
I will quote myself before you react
early impression
tldr, wish fulfillment edgelord revenge of former bullied loser that reduce women to object of conquest just because magically choosen by "fate" (god but brain dead) only need dick to "win" women because brain dead god configured it to be so.
would be nice if I'm proven wrong...
