#Rei Kibutsuji

[echantedtoon]

Kinda like my last post but more poly. Auish so barely anything's cannon. Kimetsu Gauken based. Artwork not mine both found on Pinterest. Will probably contain some headcannons from my Kagamane x Reader headcannons post too.

-How did you catch the attention of these two couples? You literally had no idea.

-You only knew that you were Muzan's secretary before he hired Kokushibo to take over your job as he was 'better suited.' But unbeknownst to you, that was a way to just get closer to you by Muzan and his wife.

-You've been working for the couple for over two years having been hired by Two to help the both of them manage their companies. Muzan wasn't happy about his wife hiring someone without his say so but relented the because his wife was happy with you.

-You did a very good job honestly. Papers were always perfectly filed, and you were very organized and clean. You kept up with his own and Rei's Business deals separated unless needed to be combined. He couldn't remember how many times the last secretary mixed up their appointments and costed them time and money. You were also on time all the time everyday and had materials at the ready for whatever he needed.

-Rei was quite satisfied with your performance as well and he liked knowing his wife was happy so he didn't care about her inviting you to have small lunch breaks with her and their daughter.

-Their daughter was quite taken by you as well. Smiling and talking about how nice you were and how you had help her learn how to spell a big learn that won her spelling bee at school.

-Rei quite agreed you were quite a charming lady and she wouldn't mind having you around more often. He agrees.

-While you're professional and perficiant in what you do and your bubbly kind and positive personality added a bit of fresh air into the office and at the same time you weren't overly positive for him to find you annoying. If fact he quite looked forward to the way you treated him every morning with your bright smile and a cup of his favorite coffee. How you and Rei smile like old friends and get along so well. How his daughter is always excitedly bouncing around and showing off what cool new facts she learnt 'from the nice office lady'!

-Its inevitable they would find someone as cute as you unable to resist for long. It's not surprisingly Rei that brings up the subject first while at breakfast and he's reading a newspaper. "Dear, Y/n was so kind to teach our little darling how to easily spell arithmetic the other day." "Mmhm. Very nice." "You know I don't think we're really giving her a position she deserves. You've always said that I could use a personal assistant for my work." "Darling, you just read my mind."

-You are shocked when the happy couple announced that you were fired from your secretary job but they were moving you to be Rei's personal assistant. You gingerly try to reject the offer but they insist having already replaced you with Kokushibo who turns out if far more efficient.

-So begins your very awkward new job as Rei's personal assistant. Some of it isn't too different from your old job minus following her around during the day. You still file paperwork for her and handle calls if she's busy, but now you also did things for her such as getting her awkwardly massive food orders-

"I have your double shrimp salad bowls."

"Oh thank you. But I must've gotten too much. You eat the other one you've been working so hard and deserve some food."

And going shopping with her as she gifts you extra items she ..accidentally buys an item she didn't want.

"I have all your bags, Ma'am."

"Thank you. But it seems I accidentally bought the purple heels instead of black."

"Shall I call the store and request a refund for the shoes?"

"No need. You can keep them. They're your size anyways."

-You also start to help out Rei's husband by rearranging furniture in his office as he works and gauges your help in certain things.

"I want you to take this."

".... It's an address and..IS THIS THREE THOUSED DOLLARS?!"

"Yes. I'm thinking about buying a share at this new retreat but unfortunately I'm far too busy to go myself. Go check yourself in for a week and report back to me anything wrong with the place."

Even when you go, granted having a good time, and comeback with your positive feedback you don't see any shares listed for the retreat in the financial database. But he does use your help in other situations too-

"Is this a dinner reservation?"

"Yes. I'm interested in hosting a business dinner together with some investors next week. Go to the reservation and see if their food is up to my standards."

You are concerned when he sees no investors the next week.

-You start to get very awkward when Rei requests you start doing more personal things. Like tutoring their daughter and picking her up from school and playing with her when they're busy. And staying to have dinner with them multiple times a week even if you decline.

-You unexpectedly get a raise despite doing less work than your last position.

-You get invited on outings together to help watch their daughter but for some reason there's always a place set aside for you or the reservations always included a fourth person.

-You get random gifts with excuses-

"My daughter thinks it's your birthday and she'll be upset if I didn't at least gift you some flowers."

"Here. I never used this dress anyways and they got my size wrong."

"My wife misplaced her necklace so I ordered a new one for her. She just found the old one today so you may keep the extra."

-One day you pick up their daughter from elementary school and she's just happily chatting away in the back seat.

"I can't wait for Mother's Day. I'm gonna make you and Mommy the best cards ever!"

"Aw. You don't have to do that. I'm not even your mom."

"Not yet! You have to marry them first and I'm gonna be the flower girl!!"

"Haha! I'm not marrying your mommy and daddy."

"Huh? You're not?"

"Of course not. What made you think that?"

"Because Daddy says I can be the flower girl! Mommy even picked out matching dresses for all three of us in that fancy magazine!"

-Both are a mixed reaction when they receive your professional company email that very night explaining that the hours were starting to get bad for you so you were putting in your two weeks and using all your company vacation days for that entire week so they didn't have to trouble you for a final paycheck.

-Rei is absolutely shocked and very, very confused. Why did you suddenly quit? If the hours were getting to bad then they'd be happy to talk with you about it and rearrange things.

Muzan is pissed. How dare you just quit on such short notice?! After everything they did?! You didn't even have mind to tell them in person!

Both try calling you but get nothing but voicemail, their emails go unanswered as well. Their daughter is very upset. Why did you leave? Weren't you going to marry them?

-Unbeknownst to the couple you use the extra money from your sudden raise to move away to a new residence. Blocking both on your old email and phone before completely getting a brand new email address and number and being sure to block them again on those too before gathering up all the unwanted gifts up to mail them back being sure to include no return address.

-After laying low for about a month you decide to go back out to job hunt. Eventually finding a secretary position open at a local school after the old secretary retired! Perfect! You end up calling the number listed for the principal and she's nice enough to arrange an interview for you with her husband, the Chairman of Kimetsu Academy.

-The interview actually goes very well! Mr. Kagaya Ubuyashiki is a very kind man and his wife is also very kind and both of them were impressed with your resume. You got the job the day!

-You're a little out of your territory being in a a school setting but slowly things start turning. You start to really enjoy your job at the Academy. You've already made friends with a few teachers like Kyojuro and Gyomei.

-Students start to like coming to the office more because of how bubbly and friendly the new secretary is. The teachers start to talk to you more often and invite you to staff parties and outside work events. Events that you were free to DECLINE and no one was giving you an uncomfortable feeling.

-Was working your old job really that stressful? You couldn't remember the last time you actually felt appreciated or just had someone treat you normally.

-Kagaya thinks it's amusing watching you shyly peek into the doorway to his office with papers clutched into your hands and bashfully asking if you could come in. The way you so innocently look unsure of something or squeak out a question. It's adorable seeing your attempts.

Amane finds your sweet and bubbly personality is perfect for the job! Especially when she sees how much you love interacting with the students and always friendly towards her own children. When you shyly ask her for help with scheduling or ask where a certain file is, always puts a smile on her face.

-Speaking of the Ubuyashiki children, you adore the quintuplets! And don't mind watching them in the office for a little bit if Kagaya or Amane was running a little late or had to do last minute work. Because they always asked you if you'd be alright with it first and didn't expect you to do anything outside your job.

-Somewhere along the way they ask you politely if you'd like to have dinner with them without any expectations for you saying yes and you agree wholeheartedly. Making it a weekly thing where you all would all have dinner together Sunday night.

-Muzan and Rei really don't know where you went for the longest time until he just happens to mention you in front of Nakime who recognizes you instantly and reveals it to him.

-Muzan is absolutely RAGED to find out not only are you working for his cousin but seemed to be dating his cousin and his wife!! Rei has to hold him back and tell him to not do anything dumb before he goes to do anything actually dumb like storm into the academy and yell at everyone.

-Instead he furiously calls his cousin and DEMANDS to know what the hell he thought he was doing!! And DEMANDS to let him talk to you THAT INSTANT!!

"Oh yes. You're the really weird bosses she was talking about. How's your dating life going?"

"YOU FUCKER!! IF YOU DON'T DO AS I SAY I SWEAR YOU'LL PAY FOR IT ONE WAY OR ANOTHER!!"

"How do you both manage to get married but still pull no bitches combined?"

"YOU MOTHERFU-"

Rei later scolds him for cussing in front of their daughter at her cousins and for chucking his phone off their second story balcony.

-She tries to later apologize for his tantrums via calling Amane who firmly states that they were not to go near you but much more politely.

-Your're later very surprised to discover that Muzan and Kagaya are actually cousins but it doesn't change your opinion on the Ubuyashikis because of how well they have been treating you.

Rei and her daughter most likely shortly died after Tanjiro met Muzan in Asakusa, and it's partly Tanjiro's fault. Just think about it.

Muzan often uses others to blend better in society, often killing women's husbands and taking their place later by wooing the women and using their status or resources for his research, if his disguise is discovered by the corps, do you think he'd leave any witnesses behind?

No, so after being seen by Tanjiro and seeing the hanafuda earrings, filled with anger and frustration of those memories, and adding to the fact he was discovered, where do you think he'll take out that anger?

If Tanjiro hadn't followed Muzan there, Rei and her daughter would've lived longer, maybe long enough for Rei to be verbally abused by Muzan to the point she offs herself(like his five previous wives).

Yeah, Muzan may be beautiful, but he's really rotten on the inside lol.

Things that went through my head in this episode:

--I'm hurting real bad in my Kamado Tanjiro feels, for two reasons.

--First, something that stuck out to me in the previous episode, and which I just checked against the manga, which has the same--the moment the Swamp Demon's head begins to appear from the ground, Tanjiro starts going into the 5th form. Yeah, that one. He changes it part-way through when he saw there were more heads he needed to target, but his very first inclination was to try to offer mercy. (Granted, we also see him slice this same demon's mouth when he starts going off about needing to eat girls while they're fresh, Tanjiro's mercy does not impede his righteous anger.)

--Second, we all remember that understanding smile he gives Kazumi in response to Kazumi lashing out, but I did not recall the words Tanjiro says to Kazumi right before that. These words are so very familiar, though, you know why?

--BECAUSE IT'S THE LYRICS OF THE "SONG OF KAMADO TANJIRO" AAAAAAAAAAHHHHHHHHHH I was very close to tearing up at this part, aaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhh

--Ok, let's set aside how much I love Kamado Tanjiro and what this rewatch is doing to me by focusing on how little I cared about the Swamp Demon that I didn't even notice in my watch of the previous episode that he does not, in fact, wear a hat.

--That being said, though this battle feels forgettable now after everything we know comes after it, on my first watch, it was pretty interesting. Beside the mechanics of Tanjiro fighting in a space where he doesn't have ground and must rely on the power generated by one of the forms he has practiced, we get to see Nezuko through around her strength and it is a blast.

--There are two things that I love that the Swamp Demon points out for meta benefit about Nezuko. First, that her moves are simple--I've always stood by my analysis that Nezuko is all instinctual power and no finesse, she fights like an angry toddler, but it is so much fun to watch her ignore finesse and throw her strength around willy-nilly with kicks and punches and stomps. Second, that she must had been bequeathed a very large amount of [Muzan's] blood to be so physically powerful. I love that we never really know how much of Nezuko's strength is due to Muzan experimenting on her with lots and lots of blood (making her ability to get away from his curse all the more impressive), or due to Nezuko sheer force of fill to make herself stronger (also very, very impressive).

--I love how this fight also makes Nezuko seem delicate once she's injured, for she does still have the frame of a younger sister whom Tanjiro wishes to see no harm come to.

--I love how Nezuko still needs so, so, so much sleep at this point in the series.

--I love how we see Nezuko's thoughts and understanding of both Tanjiro's instructions, and Tanjiro's strength.

--I love Nezuko

--On the titular character of this episode, this series really wasted no time in sending us straight into the main baddie one episode after he was named, even on my first watch I was like, "wait, really?" and Muzan is as stunned about this as we the viewers are.

--He looks at Tanjiro with the disdain of someone who has just found a flea on their fur coat.

--"Kokushibo, are you seeing this? There is a flea on my coat."

--Muzan has insulated himself from the Corp so thoroughly that having this small fry, whom he couldn't even recognize as a Corp member until he had laid a hand on him and Muzan had to actually turn around and look at him, actually get within a mile of him is so ridiculously incredulous that Muzan doesn't even know what to do at first. This isn't supposed to happen. This never happens. WHAT.

--Backing up a bit, Swamp Demon's fear was totally believable.

--And here we have our first taste of what kind of villain Muzan is--a simple one, who really, truly, blatantly has no regard for anyone around him, showing zero hesitation in causing a major distraction. That's really his whole character right there, the fact that he never develops plays in perfectly with how he believes himself to be a perfect being already.

--Other note, I love the bright character lighting used in the nighttime Asakusa scenes, and they feature prominently the building upon which Uzui stands in the Yuukaku opening! I'll be reblogging that nerd post as I get into Yuukaku, but suffice to say here that they put a lot of effort into the time period accuracy of Asakusa.

He enjoyed your presence. As he now stared at your smooth, naked back facing him on his bed, he ran one hand through his curly, dark hair and sighed. He was not someone who grew attached to people. Feelings were foreign to him. Maybe he never learned how to love, or maybe love was never instilled into his heart. You, however, you had disrupted his whole life.

He blamed it on your laughter, or on the way your eyes glistened whenever you talked about something you liked. You were so innocent, at times. He loved the way your eyes widened and you hummed in delight, whenever he made you try some exotic dish you did not even know the existence of, until the menu was kindly handed to you by the gloved hand of a waiter.

He did not mind spoiling you.

You were young, your delicate features were a blessing to him. You were the sugar he needed in his sour life.

Glancing at your sleeping frame one last time, he reached his hand towards the nightstand, grasping his lighter and his cigarette pack. Another habit of his not even you could help him get rid of. He opened it absent-mindedly, only to realize it was the last one. Perhaps, it was truly time for a change then.

This cigarette was his last one. And you, you were the last woman he would have ever let step into his life. It was time to settle down, after all. He had spent too many nights in random downtown bars, hooking up with strangers he never remembered the name of, only to search for something he never found: warmth.

You were not supposed to be different. You were supposed to he as shallow as the others, but you were not.

It happened eight months ago. Chatting with your friends, drink in hand, you had caught his plum red eyes that infamous saturday night. Ignoring his presence was impossible. A man like him was too charismatic not to draw attention. The way you had tried to resist him, though, that had made him crave you. He stared at you from his stool, shooting captivating glances at you, trying to make you understand that he was demanding your attention. Defiantly, you barely locked eyes with him, almost making him lose his patience. In other circumstances, he would have probably picked someone else to give him the proper attention he demanded, but there was something about you that made his blood boil.

He wanted you that night.

When you suddenly stood up and slided onto the stool next to his one, still pretending not to see him, he chuckled. You were a delicacy, a rosebud in a nest of thorns ready to wound him, but he was old enough to know how to play his cards right.

“A double whisky, please” you asked the bartender, but Muzan interjected in your conversation.

“It’s on me” he smoothly said, half-lidded eyes staring at the liquid into his own glass.

It irked you. Did he just buy you a drink?

“Yeah, it’s on him” you replied sassily then, averting your eyes from the barman to look at him. He was handsome, elegant, older than you. His cologne pierced your nostrils as you leaned slightly closer to him to search for his eyes, the red eyes he had made sure you would have never been able to shake off of your mind ever again.

“Apparently, you’ve finally got the hint” Muzan lowly said, twirling the rum into the crystal glass before drinking it down in one gulp and gently settling it back onto the counter.

You grinned and propped your elbow onto the marble green surface in front of you, your chin rested on the palm of your hand as you watched the barman grasp a bottle to fill your glass. It was thrilling the way he felt so self-assured, his presence alone was enough to make your head spin.

“Don’t flatter yourself. I was just thirsty” you said, earning a chuckle from him.

“You could have asked the barmar to refill your glass from the table” he pointed out, shifting his position to turn his body around and face you properly.

Your cheeks flushed up and, when the glass of whisky was slided towards you, you were quick to grasp it to focus on something else that was not him. You failed so effortlessly though.

“What is it that you want?” you asked him eventually, raising your glass towards your mouth and biting down on the rim softly, before taking a sip of the liquor. It burned down your throat, just like his eyes burned on your skin.

Muzan did not miss his chance and let his eyes travel up and down your small frame. You were perfect, perfect for what he had in mind. Smaller than him, delicate and bold. Being a CEO took away his energy, he needed a distraction and you were a good one. Too precious not to ruin.

He leaned forward, his hot breath fanning your earlobe as he grinned and moistened his upper lip thoughtfully. It was clear that you were affected by his actions. He could see the way your breath hitched and the way your grip on the glass tightened significantly as he spoke “Frankly, just your mouth around my cock” he whispered only for you to hear.

Your eyes widened and you inhaled sharply, as his words sank in. He had no filters and you could not blame him for it. Why? It was probably the force of habit. A man like him could snap his fingers and obtain what he wanted right away. The thrill of doing such a dirty, lewd thing to a stranger, to a man like him, someone you would have probably never met again was tickling your most dark fantasies.

It took you several seconds to make up your mind. You sighed, gently setting your drink on the counter and glanced at your friends from above your shoulder. They were staring at you curiously, some of them probably wondering what you were about to do in excitement and some of them were honestly analyzing the scene with wary eyes. Indeed, the latter ones were the wisest.

“I have a dignity” you pointed out, darting your eyes back on Muzan.

“Growning up, you’ll find out there are things far way more valuable in life than what other people may think of you” he promptly replied, straightening his necktie casually. He seemed tired and not the kind of man who wanted to hurt you. He was not going to coax you into giving yourself away, he just hoped you would say him ‘yes’.

And you did.

As you two stumbled out of the bar fifteen minutes later, you knew you were probably going to either regret it for your whole life, or look back at it as an exciting adventure you had had with an older man on a boring night. He had told you his name was Muzan Kibutsuji. He had whispered it over your lips, right before pinning you against his car door.

His lips captured yours in a fervent kiss, holding your face with both of his huge hands, as his tongue entered your mouth with expertise and elicited a soft series of moans from your throat. It was not just his experience that blew your mind: it was him. It was clear as he unbuckled his belt, in the privacy of his car, and tangled his fingers through your hair.

He locked eyes with you, searching for the slightest sting of fear. He would have stopped immediately, if he had spotted it. Yet, there was just the hunger of anticipation in those glimmering eyes of yours and he firmly but carefully pushed your head down towards his crotch. With your eyes closed, you did your best to pleasure him. Your tongue twirled around the tip, right over the sensitive spot, making him groan softly in pleasure.

It was exactly what he needed. As you began to suck him off, you were slowly making his problems fade away and stress flow right into your warmth mouth. You almost gagged as he bucked his hips up in pleasure and he lolled his head back into the leather headrest, exhaling through his nostrils. When you were sure he was just going to let you finish him off like that, he surprised you.

“Stop” he breathed out, shifting on his seat to grasp the wallet from his pocket.

As he pulled out a condom from it and ripped it open with his teeth, you stared at him in both excitement and fear. Was he going to simply take you without a proper foreplay? You were about to point it out, when he grasped your jaw and planted a tender, passionate kiss on your lips to silence you.

“I am nothing like those dogs you are used to. I know how to properly stretch out a woman” he whispered, almost offended that you had thought so low of him.

“I didn’t—” you tried to apologize, but he simply scoffed and made the words die on your tongue as he pushed the thin fabric of your panties to the side and began to draw smooth figures eight on your bundle of nerves.

You moaned, blushing faintly in the dark car as you finally met a man who knew how to touch you properly. What did you expect? He was twice your years, a man of class, of power. He had told you himself he was not like the guys you were used to.

“You are beautiful, by the way” he whispered lowly, watching the way you arched your back as he thought you were wet enough to take another step. You hummed, squeezing your eyed shut as you adjusted yourself to his thick fingers. It was too much, it was overwhelming, and you could not believe what was truly happening.

He was so skilled that you had almost forgotten you were in a car, in a desert parking lot. You wanted him, you wanted him more than that, therefore you opened your eyes and gripped his wrist gently as a sign for him to stop his ministrations. You were ready for him. For all of him.

And as you straddled his lap, allowing him to guide your hips down to perfectly sink onto him, you knew things would have never been the same again. The thing was that, despite the rather brute way he had told you what he wanted from you, he did not just fuck you that night. The way his mouth hovered over yours, the way he held you so close to him, as if he was afraid you were going to slip away from him grasp, made feel something more.

There was loneliness in that passion, a void that needed to be filled.

Bouncing on his lap, you tugged at his hair, your thighs trembling as his shaft kissed your cervix and his mouth kissed the exposed skin of your neck. He had finally found it: the warmth of a young heart.

Now, putting his cigarette out on the silver ashtray he keeps on his nightstand, he grinned and rolled on his side. Resting his cheek on the pillow, he watched you. He never grew tired in doing it. You were a piece of art from a private collection, a gem. His fingertips glided down your naked back, trailing up towards the spine and grazing over the shoulderblades. You were his. You were his and no one else’s.

You hummed at the feeling, gently lifting your head to glance up at him. Your sleepy eyes always got him and, although he forced himself not to smile, you could swear his upper lip twitched.

“Hey…” you whispered softly, half-lidded eyes staring at him in adoration.

He did not say a word, he simply stroked your hair as if he wanted to lull you back to sleep. Yet, you had learned to read him and his poker face. There was something on the tip of his tongue.

“What is it?” you inquired, not moving an inch but keeping your eyes locked with his red ones.

“Nothing”.

“Liar. I know that look on your face. You want to ask me something. — you replied, sitting up and letting the silky blankets pool down over your waist — Speak up, Kibutsuji” you invited him to talk, poking his biceps with your index.

He loathed your childish ways to make him give up and talk, but he was almost defenseless in front of them. You were his greatest weakness.

“Actually, I got no questions for you. It’s just that… Well, I’m falling for you, I guess” he confessed.

Never in his life he had pulled down his mask like that. However, a love confession from him was overdued. He spoke his mind no matter what. He was not scared of his feelings for you. It was just that, for the first time ever, he did not want to ruin you, as he thought he wanted the night you two met.

You stared at him with your lips slightly parted, your cheeks heating up, as you scooted closer to him and snuggled into his chest. His chest, where you could hear his steady heartbeat, was your favore place to sleep. It comforted you.

“I love you too, Muzan” you mumbled, closing your eyes as you felt his arm flex and wrap you up into a tight embrace. There was no escape.

Maybe it was a trap, maybe it was the highway to paradise. You did not know for how long it would have lasted. All you knew was what you felt and, in that very moment, you wanted him as much as he wanted you.

Until you filled the void in his heart. Until it broke your bones. Until it hurt.

Muzan Day 2023 - Rei and Fem!Muzan.

Muzan Kibutsuji - SFW & NSFW Headcanons

[Note: Relationship Headcanons of Muzan Kibutsuji from Demon Slayer. Reader will be human and a regular citizen for this scenario. Will contain NSFW and slight manga spoilers (just one) so minors/anime-onlys, please do not interact.]

SFW:

Oooooo wee. Mr. Grumpy for a Living himself. Being in a relationship with Muzan can be.... interesting. It can be a lot of things. He can act "generous" and spoil you like a princess or just outright mean as hell. Either way, you'll be treated more as a pet/prized possession than an actual partner.

Muzan, or Tsukihiko, first met you while he was on a stroll with his beloved "wife and daughter." You were minding your business, and the demon just couldn't keep his eyes off you. Of course, the demon chastised himself for even looking at anyone like that, much less a mere human. But, longer he had his eyes on you, the more he wanted to know about you. So, he began planning your move into his castle and his life. This Demon King wanted his Queen. Well... to be more accurate....

He was in need of you.

From your point of view, you noticed Muzan's intense gaze on you that night. To say you weren't fazed by it would be a bold-faced lie. You tried to shake off his glare, but something within you made your eyes turn towards his. The shivers that enveloped your spine, the slight hitch in your breath and body language, none of it went unnoticed by him. Those ruby red eyes of his.... it's like they put you in a trance. One that made you want to know more about him.

The next time you saw Muzan was during a local event in your village. As you went to approach him, the alarm bells in the back of your mind began to ring. Your logic was telling you to stay away from this man at all cost. Deciding to put those thoughts behind, you approach the demon and introduce yourself. Muzan was a bit surprised that you made the first move, but all it did was make his plan of having you that much easier. Giving you a warm smile, he returned your gesture and bowed politely.

“It's a pleasure to meet you as well, (Last Name). I'm Tsukihiko. I apologize for my staring the other night.”

Such a suave liar.

From that day on, a steady friendship ensued between the two of you. Friendly trips to the market, hangouts at local events, night walks in the village. All of it made you come to like Muzan even more. To the point that those feelings became rather.... loving. Initially, you felt guilty for even developing them. The thought of being with a married father made you feel icky. But, being the oh so attentive person that he is, Muzan took note of your inner dilemma and immediately knew how to dissolve those worthless worries. All it took was a fake smile and gentle reassurance.

“(Name), I've come to sense that you're worried about Rei. Well, I can say that it is not necessary. We got a divorce as of recent, and she took our daughter with her. A factor of why is due to what I am.”

Muzan then told you about him being a demon. How he had to consume flesh to survive. This new information made you feel highly conflicted, to say the least. Before you could even process his confession, you heard a twang and found yourself surrounded by a multitude of buildings. You go to question him, but what you saw made your body freeze. Those ruby red eyes you fell for were now a harsh, blood red with slits. The caring Tsukihiko was really the ever atrocious Muzan Kibutsuji, the King of all Demons.

The devilish man stood in front of you, caressing your cheek gently, despite the look of possessiveness in his eyes. It was at this moment that you knew what you were dealing with. It terrified you, but.... it also intrigued you. It only made you fall deeper in love with him. Which is exactly what he wanted. “From this day on, you are mine, and mine only. No demon or man is allowed to be in your prescence, much less look at you. Such filth shall not matter to you. Ever. Do you understand.”

As most people say, Muzan has achieved the rich status and will pretty much spoil you. Anything you want, he's already at the place, cash in hand. That kimono you were eyeing? Already in the closet. A piece of jewelry you talked about getting? He's already putting it around your neck. This man has bought you so much stuff that you feel like a spoiled princess rather than his s/o.

Affection is very rare with him. He's not exactly the romantic type, but when he's in the mood for your touches, he'll just stop you from whatever you were doing and sit you in his lap. He'd caress your thighs and deliver small kisses to your neck. He would hold you tight, almost clingy, but these moments always made your heart flutter.

NSFW:

Now, you know this man is experienced. He's lived for over a thousand years, plus he had five wives in the past (though he treated them like complete shit). Muzan has the knowledge and skills to make the human body experience the ultimate pleasure.

If it weren't for Muzan's ability to hold himself back, he would've jumped on you then and there. The site of the soft ropes decorating the canvas that was your body made him aroused. He decided to heighten the experience by blindfolding you. The demon began to circle you, using the tips of his fingers to stroke the skin of your tummy, goosebumps appearing in their trail. He then moved them to your lips, letting them invade your mouth. You happily sucked on them, a soft moan emitting from you. An amused smirk formed on Muzan's lips.

“Such greed you have. Are you so reluctant to suck on my fingers? Perhaps my cock would be a better option for you then? Hm?”

It seemed his statement went straight to your core. As he stood in front of you and adjusted the rope to spread your legs, Muzan chuckled at the sight of your pussy drooling. Kneeling down, he delivered a series of kisses to your clit while sliding his middle and ring fingers in. To say you were a whimpering mess was an understatement. A combination of not knowing when or what he'd do, plus the feeling of his slender fingers, your cunt sang a song of joy for him.

Muzan is definitely big. He's definitely a good 9 inches and would increase its size to a 10. His cock has veins on both sides, and a pretty pink tip. You didn't know how you were gonna make it with a monster like that, but no worries. Muzan will make it fit. It's why this activity is done with you and you only. Your pussy is the only thing that's capable to handling him.

Your heart jumped a bit when you felt your body being suspended a couple inches off the bed. Was this man really about to fuck you stupid like this? Taking off his clothes, Muzan stood on the bed and used the tip of his dick to tease your entrance. You whined at him to stop the tease and get on with the show. A slap to your clit and the rough pace of his thrusts made you pause your complaint, your loud mewls ringing in the air.

“Cease your complaining. I'm the only one who gives instructions here. Are you that hungry for my cock that you decide to be a brat? To be so desperate as to beg me for it? So filthy. But nonetheless, I will gladly show you just how much I can offer this pussy.”

Muzan's favorite position is definitely between missionary and doggy. Missionary allows him to see you fall apart and mark your neck with his lovebites. Doggy, on the other hand, gives him access to smack your ass to his heart's content. He also loves to push your head into the mattress and fuck you harder. But, his number one will always be you on your knees, sucking him for everything's he's got.

Ya'll have more than likely fucked while he was in his female form. You never knew that tribbing could feel so good. And boy, was Muzan a master at the art. Crossed missionary, cowgirl, you did it all. Of course, she fucked you with dildos of all sizes. Some days, Muzan would overstimulate you with a vibrator attached to your clit.

“You can't handle anymore? How disappointing. You've only had four orgasms so far. Surely you can take more, my naughty girl.”

The overall lesson here? Muzan Kibutsuji is a god at sex, and you will always be left a drooling mess.

[Here's Muzan! Ngl, I went a bit wild with NSFW jdndnrnr💀. Thanks for reading! Likes, comments, and reblogs will be greatly appreciated 💕.]

Hello there :) please could I request headcanons of the Hantengu clones, Akaza, Douma and Kokushibo starting to develop feelings for a fellow upper moon demon who has the same abilities as nezuko, is sweet and shy normally but when angered or friends are threatened she goes berserk 💙💙💙

-ˋˏ ༻falling for you༺ ˎˊ- kny x reader

✰synopsis: uppermoon’s 1-4 taking a liking to a fellow uppermoon with kamado nezuko’s powers

✰additional tags: gn! reader, headcanons, mentions of blood, mentions of death/killing, not proof read

✰character order: kokushibo, douma, akaza, sekido, karaku, aizetsu, urogi

“yeah my boyfriends pretty cool, but he’s not as cool as me.” -Lana Del Rey

˚ʚuppermoon oneɞ˚

❥kokushibo isn’t one to easily think highly of others. Considering he’s the strongest demon and only second to Kibutsuji, he never pays attention to other demons’ abilities. They never piqued his interest. Then you came along as a new Upper Moon.

♡it was obvious you had potential. Soon enough you rose, gaining the title of upper moon three. It had shocked him of how quickly you rose up the ranks.

♡because of how stoic kokushibo naturally is, it’s obvious he favors you over the other upper moons. They don’t mind. They only find it shocking.

♡when he first took a small liking towards you, he assumed it was only due to your powerful aura. you’re powers catch  him buy surprise but he’ll never admit it.

♡soon after he realized it wasn’t just respect he had for you, even if you were ranked lower than him. 

♡he’d never admit it aloud but he knows he’s developed a crush on you. He’s eternally grateful he’s good at keeping his ‘little’ crush a secret.

♡however his liking to you grows stronger after getting put on a mission with you.

♡kokushibo has little care for putting effort into slaughtering demon slayers. They’re strength and skills are nothing compared to his.

♡he noticed you were the same way. But he also noticed how you would grow slightly angered whenever one of the demon slayers got too close to him.

♡curiously, he allowed a demon slayer to land a single medium-sized cut on his abdomen.

♡despite the cut not being anything for a demon, he saw how angered you got. 

♡the way you lunged forward and mercilessly killed the demon slayer was enough to prove how protective you could grow.

♡needless to say, his feelings only grow stronger.

˚ʚuppermoon twoɞ˚

❥Douma always has a playful demeanor. And after he met you, he had only joked about your strength, not taking it seriously. His passive aggressive comments immediately disappear when you take his place as the new upper moon two, making him upper moon three. oops

♡Douma became aggravated at this. But that quickly turns into admiration as he soon learns more about you. 

♡he without a doubt prefers you over the other upper moons, and he, for one, is not afraid to show it. Not like the others care.

♡douma’s admiration can so easily and so quickly turn into love for you. With not having a complete understanding about feelings, he doesn’t even know he loves you.

♡douma’s also much more attracted to your kind persona. He’s not exactly used to others presenting that much kindness to him.

♡your shyness is easily another thing he loves. He especially enjoys teasing you about it.

♡however he’s seen how you can get when provoked. It’s shocking that when something happens to you, you don’t get angered much.

♡but when something happens to your friends, that’s a whole different story.

♡you had fought by douma’s side against a large group of Kinoe ranked demon slayers. (highest rank)

♡you don’t remember much of what happened. The two of you had been easily slaughtering the demon slayers.

♡that was until Douma carelessly let his hand get cut off, as another began aiming for his neck.

♡completely abandoning who you were fighting with, you ran over, killing the slayers in a fast motion with angered eyes.

♡if Douma wasn’t in love with you before, he definitely was now.

˚ʚuppermoon threeɞ˚

❥Akaza always respects the other upper moons except douma even if they do annoy him on multiple occasions. Then he met you. Not only had you gotten along well with each other but he was impressed by your abilities.

♡Akaza doesn’t often meet shy demons. Then he met you. And despite being such a high rank, you remained with a kind and shy personality.

♡it impressed him that despite being so strong you still treated others with kindness. Most demons simply choose to flaunt their strength.

♡it only shocks him more when realizing the full strength hidden in you.

♡He knew you were strong considering your place in the twelve Kizuki. But he had never seen your true potential.

♡but with being so kind, who knew you’d have so much strength to you. 

♡of course he knows about your strength. But he‘s never chosen to look into it.

♡that was until he encountered you while you had been busy fending off a few demon slayers. They were lowly ranked. And it was obvious you were toying with them.

♡but you had stopped the moment you saw one of them heading for akaza, who was admiring you from afar

♡you had quickly killed all of them in a quick second before beginning to mumble about how annoying they are.

♡yeah, now he’s head over heels in love.

˚ʚuppermoon four, angerɞ˚

❥Sekido isn’t used to kindness. More so when it comes from demons. And he’s not precisely fond of it either. Then again, he’s not fond of anything. When Sekido met you, he was quick to assume your kindness was a sign of weakness. Your shyness only adding on to this said ���weakness.”

♡he also will not accept you’re kindness. It’s not that he gets embarrassed. It just makes him feel weak in a way.

♡Sekido will likely take a while to get used to you. A long while, at that. And in the beginning of knowing you, he definitely won’t like you. He’ll hate you if anything.

♡he’ll constantly make snarky remarks, saying that your probably just weak and don’t deserve the title of an upper moon.

♡oh, he is so quickly proved wrong. But he’ll never admit to anyone that he was wrong and he’ll just continue calling you weak, even when he knows about your strength.

♡the other clones obviously tease him about how wrong he was about you. But even they’re shocked at certain times.

♡sekido does at times think it’s weird that you only show your full potential when those you know are threatened, but he never questions it.

♡in fact, he sometimes thinks it’s nice. What? Who said that? Not me..

˚ʚuppermoon four, pleasureɞ˚

❥karaku doesn’t exactly care about your strength. That is, until he see’s it himself. He already knows you’re strong since you’ve gained the title of upper moon. But he doesn’t care about how strong you exactly are. He mainly focuses are you sweetness.

♡it’s unusual and intriguing that a demon of all creatures can be so kind and so shy.

♡so in response, he wastes absolutely no time teasing you about it. He just enjoys seeing your reactions.

♡he doesn’t exactly mean to underestimate you, but the aura you give off, he just can’t imagine you as someone that’s completely capable of mercilessly killing someone.

♡karaku later learns he doesn’t need to imagine it. He see’s it first hand.

♡he had joined for a little snack. Which meant terrorizing a village nearby.

♡the two of you didn’t know a small group of demon slayers had been residing there that night.

♡karaku enjoys playing around with the slayers before he actually kills them. And in the middle of teasing a helpless slayer on the ground, he didn’t react fast enough to realize that one had been coming up from behind.

♡the sword didn’t even make it halfway through his neck as you rushed over, tackling the slayer to the floor angrily as a small amount of blood splattered on the floor.

♡he thought you were simply assisting him.

♡until he realized you only ever got so harsh when he was threatened. You hardly even acted like that when you were threaten.

♡all in all, he found a new thing to tease you about.

˚ʚuppermoon four, sadnessɞ˚

❥aizetsu adores your kindness more than anything. You hardly ever see things like that coming from such vile creatures. And seeing it come from you easily gets him clingy towards you. He admires that despite being an upper moon, you don’t seem power-hungry. He see’s that you care about others. And he loves that.

♡he quickly notices that you’re not easily provoked. He see’s it as interesting.

♡he also finds himself interested in your strength. He can sense your strength but has never seen it for himself.

♡despite being intrigued, he’s never asked you personally. He overthinks and is quick to assume you’ll get a bit mad if he asks. Even if you have no reason to.

♡Aizetsu always manages to push his curiosity to the side and simply acknowledges how comfortable it is to be around you.

♡be never really had anybody that sympathizes with him or at least takes time to comfort him.

♡so when you came along, he found himself get attached to you.

♡it became an attachment that sooner or later turned into a crush on you.

♡he’s clinginess also means he’ll definitely follow you around whenever you have missions. It’s not like you mind it though.

♡when he eventually learns about your anger when others are harmed, he immediately finds it fascinating.

♡it showed that even when you acted harshly towards demon slayers, it was your kindness towards your friends that was acting in play.

♡he’s so in love with you.

˚ʚuppermoon four, happinessɞ˚

❥urogi is another one that totally wastes no time teasing you for your kindness, when in reality he loves it. He understands that you’re shy so whenever you open up and show your excitement to hang out with him, he gets butterflies in his stomach.

♡all of the other demons and upper moons struggle to match his energy. All except karaku but even then, it gets a little boring sometimes.

♡urogi understands your shyness, maybe not 100%, not even 60%, but hey, at least he has a small understanding.

♡and for that he gets so excited and happy when you break out of your shell and match his energy.

♡sometimes your not the best at it, but he knows your trying.

♡but it doesn’t take long until you open up to him. He treats you nicely so of course it wouldn’t take long.

♡your sweet persona is another thing about you he loves. To him, Sekido’s always rude, Aizetsu’s always a mood killer, and Karaku is… well, Karaku.

♡so a sugar sweet personality such as yours feels like a big change. A really really good change.

♡urogi doesn’t pay much attention to the strength you hold, but it does catch his eye when your quick to become protective during battle.

♡it impresses him, actually. How all your senses heighten and your suddenly 10x stronger when something happens to him.

♡it almost seems like his skills are nothing compared to yours when the slightest threat towards him is made.

i’m too lazy to do my little Taisho rumors/secrets💙

[mikaroji]

KNY music headcannons - modern AU

this was 100% inspired by @peachdies, because radiohead and giyuu go together a little to well

━━━━━━♡♥♡━━━━━━

❀ Himejima Gyomei - IDK man, I feel like his top Spotify track of the year would be "peaceful river noises" or "subtle ocean sounds." He probably also listens to a good amount of alternative rock like the Cranberries. His guilty pleasure is Dua Lipa, but don't tell anyone that.

❀ Shinazugawa Sanemi - Dad rock for SURE. Gets down to Guns n Roses, Def Leppard, and Van Halen. Is secretly a HUGE Nicki Minaj stan, but would literally die before anyone found that out. I had to come back to him after writing this cause MY GOD HE'S ALSO SUCH A LANA DEL REY FAN LMAO.

❀ Obani Iguro - Refuses to pay for Spotify premium but also constantly skips songs so half of his listening time is ads. He likes grunge punk like the Garden and Foo Fighters, but secretly cries to Mitski.

❀ Tokito Muichiro - Super into the indie scene and only a little bit pretentious about it. Strokes, Pixies, Arctic Monkeys - super vibey.

❀ Tomioka Giyuu - Listens to actual underground music and a lot of smaller bands, but also listens to a lot of Radiohead and the likes. Went through a huge emo phase with Panic! at the Disco and My Chemical Romance and still cries to Helena from time to time.

❀ Rengoku Kyojuro - Imagine Dragons makes him hyped for the morning:D But alongside that he actually has some banger music taste as well. Gets down to some City Girls and Nicki Minaj from time to time. Not afraid to shake some ass.

❀ Kanroji Mitsuri - Love love loves pop and dabbles in k-pop as well! I'm thinking Doja Cat, Taylor Swift, Ariana Grande, Lizzo, Loona, Red Velvet, and the likes. Enjoys dancing around to it as she gets ready in the morning and holds her own little concerts in her room.

❀ Kocho Shinobu - A true toss up I think. I can see her liking metal like Slipknot and Korn, but I also see her as a Fiona Apple lover so it's hard.

❀ Uzui Tengen - God he's so unbearable. Listens to a lot of soundcloud stuff and thinks he's better than you because of it. He probably also listens to a lot Lady Gaga and will probably play you a super popular song of her's like Just Dance and say something like "it's super underground you probably haven't even heard it."

❀ Kamado Tanjiro - AJR and Imagine Dragons, probably.

❀ Kamado Nezuko - Physically cringes when her brother turns his music on. She's eclectic, though. She hangs out around Mitsuri and Kanao a lot, so bubblegum pop and goth are worming their way into her heart. Traditionally she enjoys a lot of indie pop, though (think Clairo and such.)

❀ Shinazugawa Genya - Dad rock like Sanemi, except more refined somehow. He also branches out more and got super into QUEEN and the Rolling Stones. 

❀ Tsuyuri Kanao - Godly music taste, I'm convinced she and Giyuu are silently judging everyone. Goth music but like real good goth music (as a goth music enjoyer I'm projecting.) Joy Division, Depeche Mode, Type O Negative, all the classics. 

❀ Hashibira Inosuke - I don't know man....... He probably plays all of his music off of a rock. I seriously cannot decide for him. Probably listens to whatever his friends are listening to.

❀ Agatsuma Zenitsu - ONE DIRECTION BABY. But for real, I feel like he would love love love the Beach Boys! A BLACKPINK fan as well.

❀ Kokushibo - He and Kanao would get along so well because I also think he's another goth king, probably more like a Sisters of Mercy type of guy. He hates Douma's music taste, and will eavesdrop on Akaza playing Phoebe Bridgers from time to time and get emotional.

❀ Douma - BLASTS Megan thee Stallion throughout the infinity castle and knows every word to every one of her songs.

❀ Akaza - Phoebe Bridgers fan until the day he dies. 

❀ Kibutsuji Muzan - White noise.

KNY Swap Au Ramblings P2

I've seen a lot of others make their own versions of a swap au and I wanted to create one too just for fun. None of this is cannon, and not everyone will be swapped out and it'll have my own twists on things. And have some things added for new story elements.

Most of the role swaps I've seen are usually with either Sanemi and Genya or Gyutaro and Ume replacing Nezuko and Tanjiro. Or the rolls are swapped with Tanjiro being the demon instead. But for this I'm swapping out the Kamado Siblings for the Tokito Twins. I won't go into depth about everyone but I will give important differences to the story.

WARNINGS: Mentioning of killing, death, regular demon slayer content, etc.

EDIT: If you don't agree with any of the placements or head cannons that's fine. This is only my take on things.

Some people liked my Swap Demons concept so I decided to do a second but with the Swap Haishira.  If you don't agree with the placements or headcannons like before that's fine. And again not everyone will be swapped out or changed.

I based Swap Muzan partially on the swap au headcannons by @demonslayedher on Tumblr.

MASTER MUZAN KIBUTSUJI AND HIS FAMILY:

Honestly not much about him as a person has changed. He's still very much scheming, cunning, smart, strategic, and has a temper. The only difference is that he doesn't really y'know kill, eat, and murder people like Cannon Muzan. He runs the Demon Slayer corps like a smart well oiled machine and somehow he's very good at it. Of course not many people in the corps have the mind to oppose him with his temper and hatred for being tested. Despite his... personality, he's a very efficient planner and more than once some of his plans have worked in stopping demons. Despite his own short comings and the disease he has, his abilities to run the corps effectively has earned him the loyalty of most of the slayers. Even if not everyone likes him as a person they can admit he's an efficient leader. He may not always be understanding but he's smart enough to know how to approach sensitive topics and deal with the consequences that comes with having slayers and being the leader of the corps.  

Not much of the disease has changed. The only difference is that he has it in this timeline instead of Kagaya.

His wife, Rei Kibutsuji, is the one who helps run the corps if her husband's disease is too much for him to deal with that day. She was engaged to Muzan when they were both sixteen due to her family's various connections to resources and married at eighteen. Her family's various connections and resources has been a great help to the corps. Providing various medications for them to experiment with to combat the disease plauging the Kibutsuji family for generations, secret hiding courters for various slayers in the areas, Intel, and other things which helps. Her more level headed calm persona often helps to balance her husband's temper and her insight to various situations and things help him to make better choices in some instances. She is almost like a mother figure to the younger slayers in the corps and many respect her opinions on difficult situations.

They both have a single daughter, Muzan's heir, around the age of ten. Not much is known about her but she's very wise for her age and attends the final selection in place of her mother if she cannot spare a moment from her father otherwise she is always by her father's side helping him. Her first name is unknown to everyone but her parents and is a well guarded secret for security measures. Most call her by her given title of 'Young Kibutsuji'. 

HAISHIRA DOUMA:

Honestly Douma as a character and personality wise does not change one bit. He is still emotionless, apathetic, and everyone still dislikes him. But his story changes slightly as a slayer. His parents were originally followers of Gyomei's cult and upon his birth believed to be blessed by the gods with such a beautiful child. Thus child Douma became the (sideshow-) poster child whenever his parents went out with others to spread the 'good word' of Gyomei's eternal paradise cult. When he was about 8 the same instances occur in cannon. Douma's mother finds her husband cheating with other follower while out trying to recruit more followers. After killing her husband and his affair partner she took her own life leaving Douma just... standing there. Awkwardly just staring. Before just leaving to just...wonder aimlessly really for a long time until after a long time he's attacked by a demon in the mountains after attempting to seek shelter in a shrine as it was something familiar to him. A fight insued in which he nearly died if Urokodaki hadn't come along, he may be retired but he could still slay a low level demon in self defense if needed. The man is surely confused by why such a young child is here by himself, but is even more shocked by the fact he didn't show any emotion at almost getting killed by a demon. Unsure of what exactly else to do, Urokodaki decides to take him under his wing for now.

Later he did end up later learning water breathing techniques from Urokodaki along with Hakuji, and two other boys named Sabito and Giyuu who both went missing or died in their final selection. During his training Douma has formed a personal breathing style derived from Water Breathing known as Ice breathing which match his cold personality. Strongest Haishira which makes Hakuji angry. Actually was the one who ended up recruiting Gyutaro into the slayers after finding both himself and Ume in the entertainment district during a mission. He doesn't have any real reason to be a slayer other than it gives him some kind of purpose. Personally no one really likes him except for Gyutaro whom is grateful for the help he's received from him. Muzan only hasn't gotten rid of him yet because he's a honestly a very powerful force on the battlefield.

Was actually the one who found the brothers in the mountains while tracking down a powerful demon and took pity on them after seeing Yuichiro's unnatural demon behavior. That's what you're supposed to do right? Help others! He was nearly executed by Akaza for his actions at the next Haishira meeting.

HAISHIRA HAKUJI A.K.A AKAZA: 

Not much changes a lot about Akaza's backstory other than instead of poison Koyuki and her father were slain by demons instead of poison. Shocked, in grief, and filled with rage Akaza began hunting demons down on his own. He was unaware that a demon Slayer corps existed at the time until he also ended up just coming across Urokodaki in a similar fashion to how Douma was. Similar to Douma, Akaza developed his own Snow Breathing style derived from water Breathing, and fights a mixture of using his blade and his own physical body up close to deal damage with brass knuckles embedded with Nichirin spikes if demons are close enough. His previous martial art skills helps him to be flexible and untouchable in battle.  Despite studying under the same teacher and both having breathing styles derived from water breathing, Akaza HATES Douma. He hates his fake personality and how he acts all buddy, buddy to him. His mission is to eradicate the demon king and avenge Koyuki's death. The most loyal to Master Muzan. Akaza respects his serious attitude and cunning mind.

He thinks Douma sparing Yuichiro and Muichiro was a stupid idea and has mixed feelings about it all. Much rather prefers to be around the Kamado Siblings he himself recruited.

HAISHIRA GYUTARO AND UME:

Gyutaro is actually the Haishira. Ume is works safely at the butterfly mansion with Kanao, Aoi, and Nezuko in care for the slayers and kakushi who need to heal (changing my mind on Aoi and Kanao being demons). Backstory wise everything still proceeds as is cannon. Haishira Douma happened to have stumbled across the two siblings while hunting the previous Lower Moon Three in the area at the time. Feeling sorry for the two, he brought them back with him and sorta just dropped the two in Shinobu's lap. Gyutaro is extremely grateful to Douma for helping him and when the older man expressed interest in Gyutaro's already good fighting skills, he suggested that he join the corps since he has no where else to go. Unfortunately due to Gyutaro's unusual body conditions, he wasn't able to master the breathing styles Douma tried to teach them. Shinobu in a rare form of kindness after seeing Gyutaro interactions with Ume, offered to teach him her Insect Breathing she mastered because her body also isn't as strong as most Haishira. Gyutaro is the Mantis Haishira having previously learnt insecct breathing from Shinobu before her strange disappearance. He fights using his thin but flexible body like a preying mantis striking his prey. His weapons are duel Nichirin scycles custom made from his memories of using them for his job. He is surprisingly very good at killing demons and enjoys his new purpose.

Ume is often wanting to become a slayer like her brother, but Gyutaro forbids it forcing her to stay in the butterfly mansion with the other girls out of harm's way. Not much to say about her. Her whiny personality often collides with Aoi who keeps her spoiled attitude in check when making her help around the mansion while her older brother is out slaying demons. She does get the occasional visit from the Ice Haishira tho it's rare.

RETIRED HAISHIRA NAKIME:

Again not much to say about Nakime. Y'know that guy from Dororo who can use the sword in his biwa? Yeah that's her. Retired Sound Haishira. She can still slay demons with ease however she has retired after killing the Demon Tengen and his wives with a few other Slayers and loosing her eye I the process however she remains behind in the corps to help Urokodaki and others train the new slayer recruits.

HAISHIRA HANTENGU:

Not much is known about the quadruplets and their younger brother. They were all brought in one way or another from a horrible family situation by Rei after their grandfather Hantengu had a mental break and their father Urami just up and left them all. 

Sekido is the oldest one and trained with Kaigaku and Zenitsu by gramps and is a few years older than them. He and Kaigaku are always butting heads and tolerates Zenitsu only to an extent because he reminds him a smidge of Aizetsu. But otherwise he dislikes the 'whiny lightning brat'.

Aizetsu is the only current water breathing Haishira after training with Urokodaki and mastering the style. He deals with depression after everything he endured and is always worried about his brothers especially Zohakutan being the youngest.

Karaku is the current Wind Haishira. Self explanatory. Often he's paired with Sekido for missions. Despite the two brothers fighting like cats and dogs with rabies, they are surprisingly very good at fighting together during life or death situations. May or may not have a crush on someone in the corps.

Urogi is the only Hantengu brother who isn't a Haishira or Slayer. He is unable to use any breathing styles unlike his other four brothers. No one is sure why and honestly he's a little disappointed and sad, but he found a good purpose of helping to care for the many messenger crows that the corps uses. He's surprisingly very good with them and even matched many crows with their perfect match in a slayer including all of his brothers and surprisingly Akaza. Is the closest with Zohakutan as he's always the one who constantly keeps tabs on baby bro using his birds. Zoha thinks it's annoying but the comfort of having someone to fall back on for help is comforting to him.

Zohakutan so far is the youngest Haishira only a few years younger than his older brothers at 14. He's developed a breathing style all on his own Nature Breathing after his three Haishira brothers all tried training him in their own breathing styles. Somehow Zoha was able to mix the three plus add his own differences to create his own unique breathing style. It's proved to be very effective against demons. He's very loyal to Master Muzan after he let them stay and takes killing demons very seriously. Possibly more seriously than Sekido and honestly is always trying to surpass his older brothers to prove to them that they don't have to worry about him. Surprisingly he likes Tanjiro and Nezuko. Tanjiro's personality won him over and Nezuko is the little sister he never had. A lot of the time you can find him sparing with Inosuke.

SWORDSMITH GYOKKO:

Gyokko is the swordsmith who's responsible for the strange concoctions of weaponry that the current slayers use and his biggest rival is Haganezuka. While Haganezuka absolutely hates, hates, HATES Gyokko making strange weapons and for constantly tinkering with the 'true beauty of the blade', Gyokko hates that his fellow swordsmiths 'have no artistic creativity!!' Gyokko is the only swordsmith who is willing to 'get creative' and take special requests from his slayers. But because of his attitude like Haganezuka he rarely gets any requests. He personally made Akaza's Nichirin spiked brass knuckles, Douma's Nichirin fans, and Gyutaro's Nichirin scycles as they actually saw an opportunity to use his creative skills. Because of that they're his favorite Haishira but he also gets upset whenever he has to replace the unique creations he made for them. It's unclear if he is the one who made Nakime's biwa sword but as the two older people talk it's not a far off possiblity. 

He doesn't just make swords and weapons. Gyokko also dabbled in pottery and has made his own monstrous mask he constantly wears. Douma has expressed the beauty in his pots and was gifted one as a result along with his battle fans. It still sits in his estate. Haganezuka and Gyokko once got into an argument where Haganezuka ended up kicking one of Gyokko's vases destroying it. That resulted in the worst fight the two had up to present day lasting for hours and ended up with both of them needing bed rest for several months. The two swordsmiths are no longer allowed within twenty feet of each other.

DOCTOR ENMU:

Enmu is by far the most hated member of the corps second to Douma...buuuut he knows his way around medicine and he owes a lot of money to Muzan so this is his way of paying it back. Despite his..'quirk' he's a competent doctor and knows a lot about anatomy. Whenever he's given a demon from final selection to disect- Study or is tasked with researching Muzan's blood and skin cells from his sickened skin, he's very creepily excited and motivated. He used to speak to Shinobu about his discoveries from dissecting demons and ask about her wysteria poisoning techniques until her mysterious disappearance. When Shinobu disappeared all of the full nursing duties became his responsibility and he took over the butterfly estate partially run by Aoi. He's since found her notebooks and journals of her experiments and continues her research. Will later assist Tamayo with her cure for demon kind.

He was hoping to study Yuichiro's body if Sekido ended up killing him but unfortunately he wasn't allowed to do anything. Still occasionally asks Muichiro for some of his brother's blood despite his disgust.

TSUNAGU KAIGAKU:

Not much changes about Kaigaku's backstory. He's a few years younger than Sekido and his brothers and two years older than Zohakutan. Like Sekido has mastered enough Thunder Breathing to become Sekido's tsunagu but not by choice. Muzan assigned Kaigaku this placement because Sekido can and WILL scare Kaigaku back into place when his ego goes unchecked including using physical punishment and harsh training when he thinks it's needed. Kaigaku HATES it and Sekido...But it's been effective and he has become more humble and has learnt to not have such a big attitude after Sekido threw him using a single hand to throw him across the room for the fifth time in one day.

Zenitsu and him fight like siblings (see Kimetsu Gauken on this-) but has learnt not to throw things at him anymore after Tanjiro headbutted him and knocked him unconscious for a few hours. Despite that he can tolerate Tanjiro and Zenitsu to an extent but always fights with Inosuke and Zohakutan. He much prefers to go on missions with Kanao and Muichiro if he's supposed to have a partner for missions as they're usually easier for him to go on missions with. Genya is like him so he can somewhat tolerate his presence if he's not being trained by someone else.

Between Sekido's harsh lessons, Muzan's scoldings, and Tanjiro's kind advise(and humbling headbutts) he's learnt to become a bit better as a person. Not a lot but better, and Tanjiro is always trying to be friends with him. There's hope for him yet.

That's it so far for my ideas on some swap Haishira. I might do a third one with my Swap headcannons for the swap Kamaboko squad and Muichiro and Yuichiro if anyone's interested in that.
