Anime characters x reader

Muzan Kibutsuji x GN!reader

Request: Idea that been on my mind for like weeks. GN reader that is Muzan's S/O that isn't well known by demons not even some of the uppermoons. Reader comes to the Infinity castle during an uppermoon meeting and gets on to Muzan about leaving a mess (Dead person) at the house and how they always have to clean the blood up. They are tugging Muzan's ear which is just surprising to the uppermoons. Nakime knows Reader cause she brings them there. Kokushibo knows reader because he saw reader in the infinity castle before doing whatever. Reader is also a demon.

Sure thing!! Thank you for requesting!

Fluff, established relationship, mentions of violence, demons, out of character Muzan/other demons.

The moon was high as the upper moon demons gathered together because of their lords command. They all stood in the infinity castle as they awaited their lord who had important news to tell them. Douma in particular was getting restless, wishing he could partake in the eating of beautiful women instead.

"Where is our Lord?" Douma asked to no one in particular.

"Be patient, I am sure our Lord will arrive shortly." Akaza replied with an annoyed tone.

"Hmmm, fine then." Douma sighed.

Just then, the man of the hour himself arrived, almost in a flash. Douma, Akaza, and the other upper moon demons all stood still at Muzans aura. Chills ran down their spines and their once proud faces were now ones of fear. They all bowed simultaneously and kept their heads down to show their loyalty.

"Mmm good to know you all still know your place." Muzan spoke looking down at them with slight disgust. The smell of blood thick in the air as Muzans latest victim lie dead on the floor.

"Yes my lord." They all spoke heads still down

"Dammit Muzan! Not again!" An angry demon called out making all of the upper moons lift their heads in surprise.

"What is it now dear." Muzan spoke calmly looking at his beloved.

"How many times have I told you that you cannot leave your dinner anywhere you want. You're the lord of all demons at least act respectable. My goodness." The new demon scolded Muzan as the tugged on his ear which surprised all of the other demons in the room.

"My...apologies, y/n. Please let go of my ear darling." Muzan spoke softly hoping his subordinates wouldn't hear.

"For what" Y/n said still holding onto his ear.

"For... leaving my dinner... laying around." Muzan responded looking annoyed as his ear was throbbing in pain.

"Good. And this time there is no way in hell I'm going to clean up after you." Y/n spat giving Muzan their best glare as they finally let go of his ear.

"Yes dear." Muzan as he looked deep in their eyes. Muzan then held y/n's face affectionately before turning back to his subordinates who gave him a look of confusion.

"What are you all looking at. If you'd like to keep your head then I suggest you bow your heads." Muzan yelled glaring his bright red eyes at the upper moon demons.

"Yes my Lord Muzan." They all said in unison.

"This powerful demon is Y/n, who also happens to be my mate. Treat them as you would treat me." Muzan ordered looking at them in disgust.

They all bowed further showing that they understood their lord's demand. Y/n then heals on to their mates arm holding it affectionat. They then looked at the sight before them feeling pride that their love is so powerful.

"Don't you have import news to tell them, my love?" Y/n asked looking up at Muzan.

"Why yes, Dear." Muzan replied looking into their e/c eyes. "I have gathered you all here today to tell you that a demon that has conquered the sun had finally come." Muzan started as he continued to hold on to his love.
