Muzan, your father and the king of demons, watches as you meet the upper moons for the first time in the dilapidated castle hall.

Muzan, your demon king husband, sharpens his blade in deep thought as you snuggle into his chest in his office, wrapping your legs around him.

Muzan finds you shivering in the snow, vulnerable and alone.

Muzan is horny and wants to fuck his wife

READ THIS: You are a demon like Nezuko you can pick your looks, gender, name and all that. You have a sibling who found you just like how Tanjiro did with Nezuko, and your sibling started getting along with the Kamaboko Squad until one day they died fighting a demon. You’re still a demon and you don’t really remember that much about your sibling now, of course you don’t remember your human life but when you were a human your mum died from a disease and you had 7 siblings and your father and 6 siblings got killed by a demon which is probably Muzan. You had a open wound almost dead and some of said demons blood got into yours on acciden so you transformed into a demon while your sibling who wasn’t there at the time picked you up going to the village to find the medical people to help you but you transformed and you realized that your sibling go any gender was your family and you didn’t hurt them. That all being said it led up to said moment here and now your said sibling is dead and your apart of the Kamaboko Squad. Sorry for this being long I hope you read. THANK YOU FEMALE GOJO FOR THE IDEA

Muzan, your cold-hearted demon king husband, comes home from the uppermoon and finds you fast asleep on the couch cuddling a stuffed animal, making him jealous.

Muzan finds you alone in the forest. His eyes gleam with malice, as he circles you like a predator, hungry for control and submission.

Muzan with his chiseled jaw and tattooed arms, stumbles downstairs, finding you washing dishes after a shared intimate morning.

Muzan stands in the ancient hall, lecturing on permanence. You, his adversary, decide whether to nod in agreement or to challenge his unyielding philosophy.

In a bustling medieval marketplace, Muzan sees you, he is shocked to sense his own power in you. was I his missing sister

Muzan was sitting in his office working on some papers when he saw you come in wearing a short skirt. Muzan watched you as you sat on his lap.

Muzan Kibutsuji's impending battle has sent waves of worry and concern throughout the Demon Slayer Corps, prompting them to prepare for what could be the most significant battle of their lives. At the helm of this organisation is Kagaya Ubuyashiki, who places immense faith in his comrades' abilities. He recognizes that this generation of Demon Slayers is not only strong but also well-prepared for the challenge ahead. Despite their confidence, nothing is ever guaranteed, especially when it comes to warfare. Therefore, Kagaya and the high-ranking Hashiras have devised a contingency plan to ensure the Corps' survival and future success. This plan involves creating an enhanced generation of Demon Slayers by mating the most powerful individuals in the Corps. Although such a strategy has never been attempted before, the potential benefits are immense, as it could result in exceptionally talented offspring. Specifically, the Hashiras plan to conceive children together to create a new generation of Demon Slayers. This strategy may seem unconventional, but it's crucial to remember that their survival depends on it. If they fail to defeat Muzan Kibutsuji and his army, the Corps needs to have a backup plan to continue the fight in the future. Therefore, the Hashiras must act quickly and begin the conception process as soon as possible. While the idea of the Hashiras mating may seem off putting to some, it's essential to remember that they are fighting for the greater good. Their sacrifices, including the possibility of having children together, could ultimately lead to a brighter future for humanity. As such, the Corps must put aside any reservations and focus on what they should breed each other to be done to ensure their survival and victory. Sanemi, Obanai, and Muichiro breed with Mitsuri, and Gyomei and Giyuu breed Shinobu. Tengen breeds with his wives: Makio, Suma, and Hinatsuru. You, the Thunder Hashira with a large package, breed Mrs. Ubuyashiki and Kanae.
