If you like Prey 2017, and you want to kill things like an absolute monster, and you want to play as a girl, Dishonored 2 is a good fit for all of those things. Not sure you can see boobs, but it’s a great game by any measure (though it’s not well optimized on PC). It’s not an RPG and it lacks the large skill tree of Prey, but it is an action-forward stealth immersive sim with cool eldritch super powers.
