Baiser's power level seems to be up and down depending on how crazy she is at the moment. I think I counted 16 visible stars after she got her butt kicked by Lorde and the Nun.
It's amazing how incredibly tender and loving this is when they're doing the deed. Baiser just wants all the ladies of the world to be their best self. Whether it be accepting your love, or not falling into depravity.
This page mentions the stars being on their skin, her horns are part of her costume and her eyes are not skin. So she is 2 stars, but they multiple the hornier she gets.
