The Monster King's Daughter (King! Adult! Asriel X Adopted! Hybrid! Reader)

It was a calm, quiet night, and Asriel, the King of the monsters, was taking a stroll on the dirt path, through the woods. It was enjoyable...until he heard the cries of a child. He follows the sounds of the cries and finds a dying woman with a small infant. (You of course.) Your mother is human but you're something more.
