The kunoichi are indeed included in the list of side girls that are likely to get preggernet.
Claire, Ami, Hana, Laura, Renee, Julie, Lucille and Molly are others that I can name off the top of my head that were on the really high priority list.
I haven’t really made a list of all side girls.
Qarinah’s situation is a bit more complex.
While Roxy simply doesn’t reproduce sexually (she presummably shapeshifted her lady bits to “play” with humans.
Qarinah having a physical form is debatable. We’ve never met her physically, and she exists in the world of dreams, that’s her “real form”.
But if you remember how her story went during act 2, I seriously doubt she’d be up for trying to make another dream succubus… Even if such a thing was possible to begin with.
So, we might get a dream baby or nothing at all.
