Sometimes, I wonder if artists have reasons other than thirst, to draw important figures like whores.
It's not just that her tits are huge and in the open, but they are being pushed against with a pseudo-bra piece of cloth like-corset, and a dress that has a slit open just enough to expose her panties at all shots that feature her.
Even if you'd argue: "Ah, she's a succubus" or some shit like that -- you'd expect the literal queen of all demons, to be more dignified. You don't need to dress like a bimbo to play your species' role. And that's especially coming from a country like Japan, that has a
history of courtesans, so drawing your highest authority like a cheap wet dream is just really fucking weird. It would have been better to just drew her completely naked, or just covered by minimal robes.
