Demon Realm AU collection

//This is a series of one-shots on ao3, so each chapter is an entry of its own. Not necessarily in chronological order or connected beyond taking place in the same universe

Welcome to Demon Realm AU, a place where, you guessed it, demons live in their own separate reality, mostly unaware of the existence of humans - or of the fact they're edible.

In this series, Muzan has turned his previous forms (kid, female and adult) into actual people and now has to deal with the consequences of this decision on top of his regular duties as the Demon King.

They are his weird little family and he loves them. Sort of. He's still learning.
