A soul exchange gives a frail girl a chance to be reborn. She swaps bodies with a max-level powerhouse from another world and becomes the warden of a prison in a demon city.
To make up for the regrets of her previous life, she vows to work hard, live well, and be an honest and kind person this time around.
However, what awaits her is a mess that couldn't possibly be any worse.
But that's all right, because I'm a max-level powerhouse.
But why does it have to be a little succubus?
There's nothing wrong with being a little succubus, really. It's just that she sometimes has a few little troubles. Whenever she sees something cute, she feels the urge to make it her pet or something...
Begone, desire! Begone, desire!
Huh? What do I do if I've brought someone home without even realizing it?
