Nobody in Promise. None of them give off the vibe that they'd like it up the ass, even with Bae making butt jokes. They're normal girly girls, not a single one of them is randomly gonna be like "Oh yeah anal's hot."
Nobody in Advent either. Your only potential there is Bijou because of the whole Thai thing, but she's also the tiniest thing on this planet, so I cannot imagine someone like that would ever be into getting fucked in the ass.
While the idea is fun to consider because we are perverts, I don't realistically see anybody in HoloEN liking the idea of having dick in their ass. It is a beyond rare fetish for girls.
