Call me dad
warnings: suggestion of forced turning, reader refuses to call Muzan dad, the upper moons are scared, reader is tied up, reader is tied up. GN reader

Tumblr media Tumblr media Tumblr media
Reader hated Muzan with a burning passion.
They hated how Muzan got angry when they didn't call him dad.
They hated how his anger was never directed towards them.
It made Reader feel like they weren't justified in their anger. But what they hated more was the forced cuddle time.
"I hate this." Reader mumbled, Muzan was having a meeting but since it was at the same time as cuddle time. Reader had to attend, they were tied up unable to leave his lap. It would feel domestic if Reader ignored the restraints.
The upper moons tensed. Muzan turned to Reader with sharp yet concerned eyes. "Are the restraints too tight?"
"I don't want to be here." Reader mumbled. "It's too loud., Muzan"
"Is it?" Muzan mumbled. "How sensitive you are, my dear but it's dad remember." Reader rolled their eyes. "Don't worry, I'll punish those pests for disrupting our cuddle time."
Reader scoffed and mumbled: "I think they should be rewarded instead."
Muzan's grip on them became stronger. "Don't say such foolish things unless you want confinement." Reader couldn't help but chuckle. "And you say I am sensitive Muu-zan~!"
It felt like a victory every time he got pissed, the upper moons terrified faces made it all worth it. "It 's dad, preferably papa." Muzan hissed.
"Oh, it is now?" Reader hummed with a grin. Muzan dragged his nails on Reader's shoulder. "It won't be when I die."
Douma looked up scared, the other uppermoons looked at Reader with wide eyes. "Are you threatening me with your death?"
They grinned. "Well, it is the one thing you can't control." Reader whispered in his ear for dramatic effect. "Is it? Perhaps I should turn you now."
Reader's eyes hardened. "As if you would." Muzan didn't want to turn them until they were an adult". But the more Reader opposes him, the more he wants to turn them. "Oh, I will."
Their young demon self would need guidance and would be under his full control. And he could command them to call him papa.
and he will take that opportunity gladly

I miss mommy muzan ;(
Okay but like you guys know how Muzan has the ability to shift into different genders and ages, so essentially he's both mommy and daddy to reader???
So imagine baby reader, who is of course spoilt to the core, demanding that she wants Mommy Muzan.
Dad Muzan, feeding baby reader: okay, open up! Here comes the airplane-
Baby reader: no! I want mommy!
Muzan: baby, she can't come rn. Let's eat-
Baby reader, tearing up and refusing to eat another bite: I want mommy! I want mommy!
Muzan, sighing and transforming into his female form: here's mommy! And here comes the airplane! Open up~

Have you ever been in booktok? You know book side of tiktok
I stumbled upon it (the DARK side) and I'm both traumatized and thrilled.
So if you have time could you do Yandere Muzan or Kokushibo x bookworm reader?
Bonus points if she reads the spicy dark shit that could make even Muzan want to cry in the corner
I really don't use tiktok~ But I get what u mean. Hope you enjoy this.
I just write this for Muzan because my brains no work with Kokushibo
Yandere Muzan Kibutsuji

Muzan had just kidnapped you.
But unfortunately he was busy.
Because of this, he didn't have much time to spend with you.
Luckily, Muzan knew you like books.
He would have stalked you.
And if you behaved well, he would definitely get you something to read.
Muzan has never read the things you want him to deliver.
And that's his luck.
This would go on for some time.
And it would work.
But then Muzan would start getting more free time.
He would demand that you spend time with him.
You're really not interested.
Muzan doesn't like this.
He would like to see what would be more important than HIM.
SKSKSKSKSKSKS
Bad mistake…
He almost dies of Cringe…
And God help him if it was something sexual ;)
Muzan would really see you in a new light.
And he wouldn't like this.
Guess who will lose their reading rights?
Oh yesss youuuuu.
Muzan would surely burn all your books.
In the future, you will spend much more time with his people.

Hii! Could I get Muzan x Reader who doesn’t wanna take their medicine (maybe they’re sick and they don’t want to take it bc it doesn’t taste nice?) I’ve not seen this scenario before so I thought it would be cool (also huge fan of your writing!)
Tumblr media
You Need to Take Your Medicine | Yandere Muzan Kibitsuji
Being the spouse of Muzan Kibitsuji means many things
But by no means does it mean that you get to neglect your health
Especially when he’s allowed you to stay human 
Now maybe he doesn’t control that maybe that's what makes you an exception
But he’s not the Demon King if he doesn’t make sure his human doesn’t stay healthy
Especially over something as stupid as taste:
Romantic
“Did I hear you correctly? You're refusing to get better? Then you’re prepared to reap the consequences aren’t you?”
If you couldn’t push through the taste orthat’sjustanexcuse
He figures its something else
But since it's you he’s willing to actually figure out why you’d do this
Its no doubt he’s making you take it 
Even if he has to hold your face and threaten to pierce your cheek with his claws
But he thinks this is only a sign of more
So now he demands that he facilitates your meals 
makes sure your hydrated 
Should he feel you're not displaying healthy behavior he’s taking over
Whether this is some weak way that you're trying to get back at him 
He’s not entertaining it
“I commend you for targeting something I hold dear. But I don’t lose and your mine. Therefore you're taking your medicine.”
Platonic
“Why are you giving the nurses such a hard time.”
“Yuck yuck, Daddy, I don’t want it.”
“You’re human. You need it. Until I can make you like me you need to maintain your health.”
“No!”
“....Fine then just eat (y/f/f).”
“Yay!”
He knows he has to be gentler
And he is actually more willing to just listen to whatever you adorably say
He’d sooner kill all the nurses whichhedid than force you to eat it
So he just mixes it in your favorite food 
Why didn’t the dolts think of that sooner he has no idea
But nothing beats a finally resting you in his arms
“Just wait for me, (Y/n) until I can rid you of all ailments.”

Guys. S4 EP1 Kny. Let's insert reader there because YESSSSSSSS!!!!!! im SO EXCITED TO BE WIRITNG FOR KNY AGAINN!!!!!!!
updated a/n: y'all, it's me, tina except now kny has s4 ep8. wow I forgot about this draft lemme continue it.
Yandere Muzan x Reader ( I hope this is yandere )
__________
You were summoned in the infinity castle, well not really summoned, just teleported to a different area since you quite literally live in the infinity castle. All because of stupid Muzan being love-sick over you. Like bro, find a new obsession or something. Stop being a creep.
"[Name], come here. Stand beside me." Muzan said without looking at you, sensing your presence as soon as you were here. He was mixing some chemicals, since when did bro know chemistry?
You obeyed nonetheless, it would be futile to resist. So you got up and stood beside him, like a dutiful pet. You couldn't help but look at all the different chemicals Muzan was mixing, like bro, tell me the atomic mass of barium!!! You had this sudden urge to poke the chemicals, so you did. "Darling, don't do that." He chided you softly, as if you were some child. Did you listen to him? No.
Soon, all of the uppermoons were summoned and Muzan went on and on like some boring professor lecture. You almost fell asleep, almost.
"Ne ne, Muzan-sama, who's the new guest?" Douma, sitting in a criss-cross position, pointed a finger at you, staring at you menacingly. You stared back, more menacingly. Soon, it turned into a staring contest between the two of you before you decided to jump down the platform where Muzan is also standing, because why not? You have free will!!
Muzan glanced at you before sighing, irritated. "Don't do it." He warned. You looked back at him, smirking. "What if I did?" You replied in a snarky tone. Muzan looked fed up with your bullshit while Douma only merrily laughed in the background, finding it amusing that someone was able to challenge the demon king. A mere human, at that.
"Don't," Muzan said, not bothering to look at you again. "What's the magic word?" You wiggled your eyebrows at him. Really, all of the uppermoons were just waiting for you to get your skull burst open because who in their sane mind tells the demon king to say the magic word? Psh, as if he will- "Please don't." I kid you not, the uppermoons let out collective gasps. "Are you a witch?" Daki muttered, looking very surprised.
You only laughed and decided to not jump off the platform. Maybe another day. It was comical seeing the oh-so-feared demon king listen to the demands of a tiny human. That, my dear, was a normal day with the feared demon king. Just some uppermoon meetings, where you got Muzan to do something polite, effectively shocking the uppermoons to their core so much that they might just go into a coma. They all have concluded that you must be some type of goddess to be able to get Muzan to say, 'please'.
_______
"Moo-zan." You poked Muzan's cheek as he read some boring ass book about flowers. He looked at you out of the corner of his eye, humming.
"I'm bored."
"And? That is not of my concern."
"I'm bored."
"I still don't understand how is that my concern."
"I'll eat your books."
"Would you like to go to dinner, tonight?" Muzan felt threatened. He knows you won't be beyond eating his books.
Silly little threats always work, guys. Try it out! Sponsored by [Name].

Muzan Kibutsuji Yandere Headcanons
Tumblr media
A/N: I'm in love with this guy, I swear I can fix him!!!
Warnings: Sadism, kidnapping, yandere themes
Tumblr media
Tumblr media
➼ You're in deep shit if he goes yandere for you.
➼ Of course, at first he's just fascinated by you. Your beauty is compelling to him, but even more compelling to him is the fact that someone as beautiful as you decided to become a demon slayer and annihilate demons. Slowly, his fascination with you becomes an obsession as he sends even more demons to find you after the last demons he sent failed to. 
➼ Once he finds you, his first plan is to cage you in the Infinity Castle. He's probably going to let you stay as a human for some time as he likes how powerful he is compared to you. Once he does find you, he's going to order Nakime to get more information from you (by stalking you) along with the location of the corps.
➼ He's felt immense potential in you since the first moment he saw you. You looked sort of familiar like he'd seen you before. It would be a mistake for him to let you let go from his claws.
➼ Surprisingly, he doesn't hate the fact that you're a demon slayer. It's actually amusing to him to see someone like you hunt down demons. But he does hate the fact that you show so much compassion for humans. In his eyes, they're pathetic beings who don't deserve you.
➼ He's a mix between a possessive and a sadistic yandere. Red flag? EVERYTHING. He's probably going to enjoy mentally torturing you by trapping you within the Infinity Castle. Whenever demons are in a fight with you, he carefully monitors them and might even give them instructions to hurt you as he's fascinated by you and is curious how you'd react. He loves observing you, that's for sure.
➼ Oh, he's never going to let you go once he's gotten a hold of you. He's going to study and solve you like a mathematics equation.

Yandere Muzan with a gn darling who suffers from migraines
Tumblr media Tumblr media Tumblr media
Request(ed?): Yes! - hiii, long time no see. Could i request muzan with reader who always has migraines? i have one atm and it’s pure hell. — requested by ❤️‍🔥 anon.
Warnings: Yandere behavior.
Authors note: I hope this is okay, i didnt check for any mistakes. Please enjoy this still!
Tumblr media
As he’s very ‘old’, he’s used to seeing humans in pain and he enjoys seeing it, but on you, he absolutely hates it and never wants to see it.
When the severe headaches first happen, he raises his eyebrow, seeing that you were sick to your stomach and weren’t eating as much; but the more he observed you and saw how you groaned from the lights and fast-movements, he immediately knew what was up.
Like the first headcanon: he’s pretty ‘old’ and well educated on the health of humans. Because of this, he will do everything in his power to atleast make you feel a bit better, such as: turning off the lamps, having a cold towel resting on your temple, making sure you stay hydrated and leaving anti-nausea near you. He will even take time off, or try too, to make sure you stay alright.
If that’s not possible, he will make sure to have Kokushibou or Akaza near you, coming at your needs and delivering whatever you say.
Muzan makes sure to not be overbearing, but you’re his pet, so he needs to make sure you’re in the perfect condition 24/7. He helps you to the bathroom, making sure to pull your hair back, and hand-feeds you if he needs too.
Though, after you’ve recovered, he goes back to original mood and disappears as much. But, he will try to go easy on you for a week or two, remembering that you shouldn’t be overwhelmed after a hellish time.
But, if you have continuous ones and that makes it extremely hard for you to do daily-tasks when he’s gone most of the night; he will end up turning you into a demon.
Like stated above, Muzan needs his partner well and perfect, meaning he will take every chance there is to make you feel better; this shows how far he will go for you.
Check out my masterlist for more yandere content!
Reblogs, comments and likes are very much appreciated!!!

Wonderful child
Platonic!Yandere!Muzan x Child!Fem! Reader
Tumblr media
You were a wonderful child not only in the opinion of your own mother, but also in the opinion of your new father, whom you and your sister unconditionally accepted. But to tell the truth, first time your new father bothered you. He may not have done anything wrong, but you were a child with an incredibly developed sense of empathy and you felt every change in his mood better than your mother and sister.
That's probably why Muzan thought you were a wonderful child. You never bothered him and when it was necessary, you left and even more, you took your younger sister away when he was not in the best mood, which made it easier him to stay here.
That night, you saw how annoyed he was after meeting with a strange boy, so when you and your mom and sister said goodbye to him, he was leaving for some business meeting. You, unlike your sister and mom, didn't hug or kiss him, just wished him to come back soon and waved.
"Y/n, I don't think you get along very well with Muzan."
You looked surprised at your mom, who was talking to you.
"You hardly talk to him, I understand that you miss your real father, but..."
"No, I get along well with Muzan. He doesn't even mind anymore if I'm in the same room with him when he's busy."
"Was he against being in the same room with you? I mean, you're a calm girl and don't bother..."
"He didn't kick me out, it's just that my presence, at first, often annoyed him, and now he doesn't mind."
You smiled at your mom, calming her nerves, and your little sister repeated after you, your mom giggled. You really were a wonderful child.
However, a good streak cannot last forever and one day it really ended. Now you were lying in bed in terrible suffering. Muzan still hasn't returned, but his money was enough to delay the progress of your illness. The problem was that neither you not your mom had the strength. You couldn't fight with illness anymore, and your mom couldn't watching you cry and moan in pain, couldn't watching your medical analysis get worse and worse every day. Your mother couldn't contact her husband, and therefore she had to make this important decision on her own.
Muzan came back at night and he was furious when he heard that he had an hour to say goodbye to you when your heart stopped completely. Not caring about the force, he pushed your mother away.
Why can't this useless woman even take care of her own child?!
When he entered your room, he discovered your unconscious figure. You were lying on the bed and looked very much like a dead, but the demon still heard your weak heart. With his claw, he sharply scratched your cheek, giving a small amount of his blood.
At that moment, your sweet dream ended, you thought that the disease was terribly painful, but it was worse, much worse. Your whole body was bending in the opposite direction, you even heard the crunch of your own bones, but all this faded against the background of your cheek, it burned with hellish pain, and the skin near the wound seemed to melt.
Your little sister ran into your room after hearing the screams. And froze in horror. Muzan sat on your bed and held you in his arms while you squirmed and screamed. The father was calm, while you beat him with your head in agony, while he held your legs and arms. The girl immediately covered her eyes with her hands and wanted to run away, but the demon stopped her.
"Come here. Don't you want to help your sister?"
She wanted to help you, she has to help you, so she listens him and approaches you. You began to shake less, but blood poured out of your mouth.
"Dad, what can I..."
Abruptly Muzan grabs her by the head and begins to squeeze.
"Y/n will be very hungry when she becomes a demon and you will help her with that."

Demon Siblings
Request: Yandere older brother Muzan with prompt D1? (love ur fics btw!!)
Tag List: @issamomma @repostingmyfavs @chickennugnugnug @palesweetscherryblossom
Prompt Request: “This hurts me more than it hurts you.”
Warnings: Yandere themes, delusions, slapping, Muzan uses his demon powers to punish you, reader tried to escape, blood, injured reader, Reader is a demon
Master List
Yandere Alphabet Prompt List
—————————————————————————
Tumblr media
Even though he says it hurts him, he doesn’t quite show it. That expression on his face is constantly neutral unless he’s lashing out in anger. It’s unnerving, especially to be on the receiving end of it, to endure his wrath.
Being a demon is one thing. Being the little sister of Muzan Kibutsuji is a whole different story. His punishments are vile, extreme, cruel, and he always tells you the same thing every time he lights your blood of fire with flames so hot they feel white.
“This hurts me more than it hurts you.”
But his tone is ice cold and calm, deadly like the venom dripping from the fangs of a snake. He glares at you with crimson irises, watching you intently as you writhe on the floor in front of him, beneath him.
You reach out for him. “B-Brother!” It’s all you can scream on an exhale. You can barely manage a singular breath.
Gripping the hem of his pants right at his ankle, you clutch his limb like it’s a lifeline. Salty pearls invade your cheeks, clinging to your damp lashes, but you haven’t the ability to cry. The pain is too much to even be able to wail.
You don’t even recall how you were able to shout for him.
The pain stops suddenly. You curl up in a ball on your side, hugging your knees, shaking violently.
Muzan crouches down, placing a hand on your shoulder. “Does my little sister still think she can go outside the castle against my orders?”
Feeling a fresh wave of defiance wash over you, you turn to glare at him instead of revering him with timid eyes.
“You say it hurts you worse, but I don’t think that’s true. I think…I think you don’t care if you hurt me, and you’re only saying that to make me feel guilty.”
“It seems you haven’t learned your lesson yet. It also looks like you’ve forgotten your place.”
An echo sounds throughout the castle, a sharp crack against your cheek, turning your head to the side. Then, you feel that same pain again, focused on your back this time. It’s overwhelming, and you feel whip-like cuts embedded in your skin.
“Muzan, I won’t leave anymore! Stop it! Brother, please?! End this! I’m begging you!”
How you regret being bold enough to say those things to him. You know better, yet for a singular second, you let all of that go to speak to him with a sharp tongue. You wanted him to know how much pain he causes you, but he’ll never know, he’ll never truly understand no matter how hard you try to convey it.
“Brother!”
You cross your arms over your chest, hugging yourself as you curl even further into a ball. The sensation in your back is growing even worse. The power your brother wields is unfathomably special, and you know that he won’t stop until his anger is satisfied. That could be minutes, hours, days, weeks from now. You never know with him, as fickle as a cat, as unpredictable as his many disciples.
Lying in a pool of vermillion, your chest heaves with heavy breaths as your glassy eyes scan upwards. You study him, the twitch upon his lips as he considers your broken form, his narrowed orbs casting a look of scrutiny upon you.
You both can’t look away from one another until he finally holds you by your arms, helping you to your feet. You take in your blood-soaked kimono with a suffering sob and wipe your eyes free of the salty rivers welling up and cascading down your cheeks.
“Don’t ever tell me I don’t care about my younger sister.” He places a soft kiss on your forehead. “Otherwise, I’ll have to show you the lengths I’m willing to go to just to prove it. You wouldn’t want that, would you?”
Shaking your head quickly, you know exactly what he’s talking about. More discipline. Muzan equates discipline with love, keeping you in line shows how much he cares about you.
“No, Brother, I do not wish it.”
“Very well, then. Let me see your back.”
You turn to him, and he sees that your back hasn’t started healing yet. He has no worries, knowing that the cuts will be closed within the next few minutes. He traces one large gash through the back of your open kimono with a finger, eliciting a sharp hiss and vocal cry from you.
“You’ll be fine shortly. Go find something to do now, something that won’t anger me.”
“Yes, Brother.”
So you disappear to your room and hide away for the time being.
All of that pain in your body, and he barely even touched you. A slap across your face was the only physical torment from him. It was his true power which tortured you into submission.
You shake your head.
I’ll never be able to escape him.

Can you do more on the demon slayer fix idea? It’s now one of my favs!
*『Memories』
Yandere upper moons × little sister reader
Tumblr media
"Why is it that you always cause trouble!Stupid child!"
"Dumb little girl! Can't you do anything right!"
The memories played through your mind like a broken record. Never ending and screeching inside your head
"You cursed child , if it wasn't for you your sister would still be alive!"
"The world would be a much better place if somthing as useless as you wasn't around!"
"Do everyone a favor and take a dive off the near-"
"Your thinking to hard again." You snap out of your little day dream to stare up at muzan who was looking ahead. You went back to looking over the edge of the mountain as he moved to stand right next to you. You leaned your head on his legs as he ran calming fingers through your head and you knew you were protected and wanted.
"They don't matter anymore you know. Their words hold no significance in the living world nor in that precious head of yours." You clenched your hands , hard enough to drag out blood from your palms. "Your a demon now. We take what we want when we want it and if anybody upsets us we destroy them."
"But what if I cant." You said , voice quite and on the verge of frustrated tears spilling out. "I can take and take untill I can't no more. What then aniki?" You asked as he gently cupped your face in hands wiping away tears that had began to fall from your face. It during these times that he rembers that you were 8 when turned into the dangerously beautiful demon you are today.
"Then you call upon one of us , And we'll take what you cant."

Chaos bitch
Warning: Reader causes chaos and tells everyone to deal with it unless they want them to continuously escape again, reader using their modern knowledge and using it to be annoying instead of a smart ass
If you can, please consider visiting my Ko-fi it's still a work in progress :)
Tumblr media Tumblr media Tumblr media
Reader thought it was time for some more chaos, they had been bed-ridden for 2 days thanks to their latest escape attempt.
And maybe it's time for a new approach, channeling their inner gen-z jokes they went on war path.
Muzan found it amusing, it was better than them escaping, so why should he punish them for it?
Well that was his thought progress until he became victim of it.
"My dear lord, can you please get Reader to stop their weird slang?" A lower upper moon asked as reader was besides Muzan reading a book. "Bombastic side eye." Reader said, causing Muzan to turn in confusion. "What was that?"
"Thin air."
"What the fuck." Muzan blurted out. "Please, my lord, we can no longer understand them!"
"Would you rather have to chase me every few hours?" Reader asked, taking advantage of Muzan's confused face. The upper moons looked shocked.
"This is my payback for kidnapping me." Reader grinned. "now deal with it."
"Reader... You shouldn't annoy your aunties and uncles."
"I can do it to you too, bitch boy."

Hear me out- what if Darling sees Muzans female form? Honestly, I think i would go feral.
Female Muzan>Male Muzan
Darling would resist Male Muzan to the max. Like biting and scratching at him, making sure his life is way harder than it used to be.
But oh.
Ooohhhhh
When she sees female Muzan?
On her hands and knees. Even barking if F!Muzan commands it.
She's down HORRENDOUSLY (and who can blame her because same)
Darling is suddenly complying with everything she asks of her or does with her.
F!Muzan wants to dress her up all nice and pretty? Darling is going to be a perfect doll.
F!Muzan wants affection? Darling is all over her.
F!Muzan asks her to speak Japanese? Darling is suddenly fluent.
F!Muzan is also somewhat softer than M!Muzan, but still a real mean girl. She's also surprised at the whole switch darling went through the moment she saw her female form.
She isn't complaining, though, and absolutely ravishes in this new attention.
Darling just admires F!Muzan, it's like a whole new person demon. They enjoy cups of tea together, dressing up together, doing eachothers hair.
It's almost like how darling is with Daki only not platonic.
I wouldn't say darling is now A okay with the whole kidnapping and weird ass relationship thingy, but she is more willing when F!Muzan is around.
NSFWISH WARNING
Muzan would also use this to his advantage in the bedroom.
Darling was never compliant sleeping with the demon, but in female form, she is allot less resistant (it's still there, though)
F!Muzan has never been a fan of change, but when she tried out all these new ways in how they could pleasure each other, she was quite baffled.
I wouldn't say Muzan likes it better in female form, but he isn't complaining either.
She's still rough, but the experience is so much better somehow.
Anyway, F!Muzan is just better in lots of ways than M!Muzan (and hotter)
But you know, at the end of the day, it's still Muzan, and darling is still trying to bite her way out like a feral toddler.

How would parents muzan and yoriichi repremind their spoiled child reader?
Muzan wouldn't, because you're angel in his eyes. Even if you're a total menace, you're his menace. Besides, what would u expect from a hybrid demon????
I think the only time Muzan does reprimand reader is when she tries to escape or puts herself in real danger. Like- he'd get real silent as he brings you back home, watching with those red eyes as a lower demon bandages you up (and if you hiss, that poor demon is dead, along with whatever demon was responsible for babysitting you) Muzan would sit in front of you, veins popping up as he tells you the consequences of what actually would've happened if something happened to you.
"The moons, i wouldve killed them. That measly fake family you had? Tortured to death. The Hashiras? Turned them all into demons. That little crush ive allowed you to have? Id drain him of life righr in front of you." Muzan cupped your cheek, as a soft smile graced his face. "I will set the world on fire if you hurt yourself until you realise you don't have anyone to run to."
For Yoriichi, I think he'd be the parent who reprimands his kid the normal way. For minor offenses, like staying up too late or eating too many sweets (Muzan had a very strong sweet tooth when he was preggers with u), he'd try the gentle parenting.
For major offenses where you end up endangering yourself, like running out into the sun without proper clothing or sunblock to protect your demon skin, or wandering out of the boundaries he'd told you to stay within, he'd use that booming, sobering voice (like the one he uses on Muzan when he was about to kill him), and it'd stop you dead in your tracks. Wrapping you in his kimono, he'd bring you back inside the house where he's giving you the lecture of a lifetime- but he doesn't use any unnecessary words, nor does he repeat. The words he chose are careful yet effective, and his tone holds such power that it compels you to obey him. Also, he grounds you/takes away certain privileges.
Overall, I don't think they'd physically reprimand you (besides making you physically stay home). You are a product of their... love? You're a part of them, and they don't ever want to hurt you.

what would yandere Muzan be like with a s/o who is married to Kagaya Ubuyashiki and has a daughter for which Muzan is platonically yandere.
Yandere Muzan Kibutsuji
Tumblr media
Muzan really hates how people oppose him.
He has a "small" god complex.
Such behavior is definitely not acceptable.
And now Ubuyashiki and Demon Slayer corp is the problem.
So the best solution is to kidnap the Ubuyashiki family and use them for blackmail.
What could possibly go wrong?
Everything
This is why you had to meet Muza.
In the beginning, Muzan was really distant.
He is definitely not interested in you or your child.
After all, you're just a way to blackmail Demon Slayer Corp.
Things only change when some lower class Demon tries to attack you and your child.
Muzan is not happy about this.
Because of this, he starts keeping you closer.
Muzan knows that if you die he will lose his way of blackmailing Ubuyashiki.
During this period, Muzan might get a little attached to you.
But he actively tries to deny his feelings.
You, on the other hand, learn to hate Muzan even more.
You especially don't want this man near your child.
Although Muzan is surprisingly good with children.
He starts admitting his feelings more.
But his love is possessive.
His "You can't go out because you're a hostage" attitude has changed to a "you can't go out because you belong to me" attitude.
The only problem is that you are already married.
Now Muzan is even more passionate about killing your husband…
He really doesn't understand how relationships work

Anonymous asked: Because you allowed me to request on your blog so I'm just thinking a lot last day to request a yandere kny like hashira and upper moon & muzan I just thought what if someone came to their place that was a spirit like in date a live I don't know if you've seen that but if you do what will they do if they meet the one who create the spirits/orginitor and when they find out the reader has a source of powerful spirits they don't think. twice when they all fights where she should stay with Hashira or Demons. That's all sorry if it's a bit difficult for you but you can research in the Google (date a live orginirator Mio takamiya) you will find it there and thank you again for allowing me to request you have a nice day and stay healthy.

Spirit Originator Reader | Yandere Demon Slayer
As a spirit originator, you’re overwhelmed with power allowing you to create spirits with powers of mass destruction. Your clothes alone can protect you without even raising your hand. Your only weakness–is your sadness. Pulled by the woeful sadness of being unable to end it yourself it only gives you two options. 1) To fill an underdeveloped world with your daughters of destruction or 2)To use your power to protect humanity from the growing threat of Muzan Kibitsuji: 
Tumblr media
The Hashiras 
They’ll have to find you before you start producing spirits
Hopefully catching your fading attention 
Not to mention how obsessed they are 
But in terms of power, they are no match for you
So force is not an option
They can only wish that you’ll stay and let them worship you
Literally working to carve out a safe haven as you live out the quiet life
The hashiras are all the more insistent on bringing Muzan’s reign to an end
Their honored if you decide to help the cause 
But they won’t pressure you
They want to keep you happy, so that you don’t destroy the world so that you’ll let them serve you wholeheartedly.
“My children are more than happy to serve you. We all are.”
Tumblr media
Upper Moons
If you’ve already created the spirits
Muzan sends them in his own intrigue
A powerful being that doesn’t value human life
You sound as though you’re one in the same
But where the hashiras realize their hubris in trying to control you
He does not
He thinks you equals he thinks he’s more powerful
So he’ll send his eager minions to pursue you and your spirits
And even without their master’s command 
The upper moons are fixated on having you 
On owning you
They hope to one day see you’re glowing powerful visage be reduced to someone eagerly bowing at their feet
A sentiment you probably won’t take kindly to if Muzan rubs you the wrong way
“Come (Y/n), join us peacefully. I have no doubt we’d work perfectly together.”

Another gen z reader pls!
YOUR WISH IS MY COMMAND.
Yandere Muzan x Gen Z! Reader.
Tumblr media
Also, this will contain TRIGGERING THEMES!! It could be anything, like mentions of murder, blood, obsession, anything yandere related. Basically dark content, so if you are NOT comfortable with such stuff, please do not read this post!
Okay, so before we start this shit, just know that Muzan here is kind of gonna be like, only good to you and shit.
Tumblr media
"My love, I'm back-" Muzan announced as he started taking off his coat like they did in those 90s shit. Or not. God, my memory is fucking shit. That does not matter, for the only goal in your mind at the moment is to find a excuse to get away from this ugly orange of a demon.
"Oh no, I forgot to water my baguettes! I am so sorry, I must take my leave right now!" Just as you said that, your baguettes in the background screamed, "Hydrate us, [Name]!"
I can't even properly tell you how hard Muzan face palmed at your so stupid attempts to try and escape his affection??? And he doesn't even wanna know who you bribed to wear baguette costumes and say to hydrate them.. What did you even bribe them with???
One of them was probably Enmu.
Muzan, himself doesn't know why the fuck he finds you so amusing. It's probably because you are like, literally playing with your life. Literally.
Evidence is the time when you once tried drinking bleach because first, it looked tasty, and second, you wanted to know what bleach tastes like.
And my God, it did not taste as good as it looked like! IT WAS A SCAM. No one ever scammed you this hard. It tasted like extremely concentrated swimming pool water.
Oh that reminds you of the time when you drank swimming pool water-
And in the Taisho Era, there is no shit like fanfics or memes so Muzan can more than often find random drawings...which are memes but his boomer brain can't process what's so funny about it. Like, talking croissants are funny- no, not the ones you find on Kids YT.
But as I said there are no fanfics, and my goodness do you love reading, proof is of you reading this. So let's hope you like reading books too.
No fanfics. What can you do? Probably read Shakespeare. I'm bullshitting my way through this, please deal with it.
Of course, after reading Shakespeare your grammar and vocabulary got a lot better! Which Muzan liked, a lot.
But,,,,, you being you, now even have more ways to insult Muzan. Like,
Thou base decayed ingested-lump!
Thou perfidious weather-bitten writhled shrimp!
Thou fawning fool-born filthy rogue!
And you could go on and on, but let Muzan have a break.
It's so funny to the uppermoons, especially Douma, when Muzan is just 'scolding' them by 'gently' smashing there heads in and you come in and go, "Awww, mama duckling scolding her ducklings..." As you pretend to make a video with your phone which you don't have because Muzan broke it because he's an asshole.
And as soon as you come in, somehow all the blood disappears and everything is normal as he kisses your forehead and asks, "What are you doing here, darling, did I not tell you to not leave your room?"
Everyone present could feel the temperature drop when Muzan said that, and that was not a good sign.
"YOU AREN'T MY MOM." As soon as you said that, you ran away faster than light because you are....idk. You were able to run away mostly because Muzan let you, but trust me when I say that he wasn't angry at you, more so at the demons who he kept at your room's door to prevent you from leaving the room.
And those poor, poor demons who were now begging for their lives as Muzan glared at them, "I gave you one job, one job.."
That's just when you had to again come in, "CUT!" You yelled, "Do it again, but this time, with more feelings." The demons and Muzan nodded, "ACTION!" You said as the scene started again, this time, with more feeling.
One time you just pointed at one ugly demon and said, "This does not spark joy," Muzan killed it. And then after seeing what Muzan did to the ones you said that to, "This does not spark joy," you said to Muzan. Pointing at him.
And after that, he was seen sulking the whole day because he thinks you hate him, which you do. I hope. I don't know.
