Maybe back when "she" was Raphael or Great Sage, but Ciel has a Manas has its own ego and emotions. That's why "she" has the presence of mind to declare "herself" Rimuru's "official wife"

And yes she does have the function, its implied she is preventing Rimuru from producing certain body parts or transforming into his own self. In other words, she can influence his powers, even if slightly.

I'm not saying she could or would stop him if he turned doomsday, I just said as far as her ability to alter his actions, she actually has the most pull.
