demon slave of a different kind ( Muzan x reader)
(I don't own Demon slayer or Hantengu or pics or vids) Okay so Hantengu in this is actually His daughter, She only goes by one main personality but holds availabilities of all. She was raised by a blacksmith Sword mans, and so what happens when Muzan finds her and senses a Uncontrollable Desire and bond to her.
