You’re Muzan’s child, an offspring with a woman, she was human, though, you turned into a demon at birth.

You were currently resting in your rockable crib that was placed in your father’s office as he put aside his work and just observed you resting, realizing how much you looked like him. He loved you, with all his heart, he has become attached.

Even though he loved you, he would have the upper moons take care of you at times when he was busy.
