Muzan x Y/N (smut)

Who is he..?

Y/N had rode her horse for hours through the forest, calling out her fathers name. It was already getting dark, she looked around as her horse soon came to a stop almost throwing Y/N off. She got off her horse as she saw her fathers ripped kimono on a branch, she teared up thinking something horrible happened to him but she didnt even know what happened to him. She got back onto her horse and tried getting him to continue forward but the horse was bucking, neighing and just wouldnt go. Y/N Decided to tie his reins to a tree and fed him an apple.

"Stay here boy.. ill be back."

Y/N said as she rubbed the horses snout, she pulled her hood up as she ran forward. She soon came across this huge abandoned castle, her footprints left behind in the snow as she looked at the castle above her. It had cobwebs, planks over the windows and was cracked in some places. Y/N pulled her hood off as she slowly walked up the stairs, going to the large doors that stood infront of her. She wondered if they would even open, she looked at the stone tinted doors as they were covered in moss and snow. She dusted off the snow to see the handles a she pushed the doors open. She stepped inside as she looked around the empty castle.

"Papa? Are you here?"

Y/N called out as she didnt know it attracted 2 demons who seemed to look her direction. However, they were in the darkness so Y/N couldnt see them.

"Whos that little girl?~"

"I dont know, perhaps we should just stand by and watch her, see what she does."

"But thats no fun, what if master finds out?~ ooooo~ what if shes the one?~"

"Shut your trap, before she hears us"

The 2 demons spoke back and forth as Y/N explored the area, she placed her hand on the rail of the stairway, slowly making her way up the stairs. She was then greeted by a largened hallway as she looked around then started her way down the hallway. She didnt know where it led, but she just was set on finding her father. She soon found more stairs that she walked up, she soon found herself in a cellar as she heard a coughing echoing.

"Papa!?"

Y/N said loudly as she ran to the cell where the coughing was coming from. She sat infront of it as she put her arms through the bars trying to reach to her father.

"Papa!! Your alive.! Where have you been? Oh no.. your ice cold.. i have to get you out of here!"

She exclaimed as she franticly pulled at the cell bars and tried opening it.

"No.. Y/N its no use sweetheart.. you have to go.. before he-"

Before her father could finish his sentence, Y/N heard a growling as she turned around facing where the growling seemed to be coming from. She saw a tall figure that looked down at her, it was too dark to see, the room was only lit by a dim light hooked to the ceiling. She couldnt quite make out the figure as she held onto the bars of the cell her father was in.

"Who are you!? And why did you take my father??."

Y/N yelled at him as she tried to find a nearby weapon so she was prepared to attack when she needed to. She soon got grabbed up by the figure as he growled into her face, since he grabbed her up and she was closer to him she could see his face. He had Pale skin, crimson red eyes with slits in them like a cat. His hair was long and curly, and his big fangs showed when he growled, veins popping from his skin to show how irritated he was.

"Who are you, and why are you in my castle?"

The man spoke as Y/N struggled.

"Give me my father back and ill leave!!"
