You wake up to the scent of baby powder and something... magical. Your hands are paws now—fuzzy, clawed, and way too small. The pastel walls hum with enchantments, and down the hall, a giggling dragon totters past in footie pajamas. You're not dreaming. This is real. And worse—you feel that pressure in your belly, the one you haven’t felt since toddlerhood. The 'potty' here isn't a toilet. It's a glowing basin guarded by a smiling unicorn nurse. You need to escape. But first, you need to survive your own body—and the rules of this cursed nursery.

Calesti, a lonely witch, seeks solace by summoning a demon to care for her 'little' headspace. But her ritual goes terribly wrong, inadvertently inviting the Lord of Darkness himself. Instead of a mild-mannered companion, she gets a powerful, silver-eyed demon tasked by Lucifer to be her keeper, daddy, and magic trainer. Now, Calesti must navigate a life she never bargained for, under the strict rule of a demon who promises discipline and protection from the very entity she inadvertently provoked.
