yandere brothers kokushibo and yoriichi (platonic):

(y/n) was the middle child of the triplets, like Michikatsu and Yoriichi quiet. At a young age, his appearance charmed others into trying to talk to him.

However, he quickly shyed away, only ever talking to his mother and brothers. The two boys didn't mind this of course, it was comforting to think that (y/n) had relied on them.

But their mother was worried, often trying to engage the middle child into conversation. So, the young (h/c) boy was often forced to talk to other children his age.

As the three boys aged, Michikatsu and Yoriichi further isolated the young man. The chained jingled loudly echoing across the estate of trapping the (e/c) orbed man.

He couldn't complain, (y/n) had a lack of energy after fighting Yoriichi. The two brothers had to wrestle their triplet for a quarter of an hour before he was too exhausted to continue.

"(y/n/n)...", The burgundy haired male spoke calmly,"I understand that you are angry but—"

Yoriichi was penetrated with a cold glare,"Of course I am, you and Michikatsu took me!"

The other demon slayer turned frustratedly,"Don't be selfish, we are protecting you and this is how you are now acting?"

(y/n) chuckled before retorting,"Protecting me — From what? The only think I need to be protected from is the two of you."

A harsh blow swung against his cheek, Yoriichi attempting to pull the oldest brother off the victim.

"Oh, so now you're acting up?", Michikatsu taunted whilst tugging at his own mauve coloured kimino,"You were well behaved before, so what happened?"

The (h/c) man shivered, backing into a corner, his wrists had become painful due to the increasing pressure.

His older brother continued,"Your attitude better change quickly, you're not going anywhere."

Black hair sprawled over, locks bouncing before Michikatsu shoved Yoriichi away furiously.

headcannons of yandere yoriichi with muzan's daughter:

𓂅You and Yoriichi are around the same age, you are only half demon and had met as children in the city.

𓂅Yoriichi had a massive crush on you as a child, however being quiet and everyone thinking he was 'deaf' could never express himself.

𓂅Unlike your father, you were able to go out in sunlight causing Muzan to be obsessive over you.

𓂅So after Yoriichi's first wife and child were killed by your father, he was devastated but never blamed you.

𓂅He was even kind of happy, yoriichi could finally have the girl he has always liked now they were out of the way.

𓂅Although yoriichi was quiet, he was used to you so he was more flirty around you and overall driving the demon king insane.

𓂅When he finally asks you out, you accept also having some feelings due to his sweet personality— You were able to love.

𓂅Soon, however he became possessive over you and lied telling you horrible things about your father.

𓂅Believing yoriichi, since he has never lied to you before you left your father and lived with your fiancée.

𓂅Yoriichi was clingy around you, yet not delusional. He knew how to manipulate you into staying and had frightened Muzan away.

𓂅Your father is a coward, he would not come to save you and instead stay far away from your now husband.

𓂅Although yoriichi is very strong he'll never hurt you.

𓂅If Muzan is being egotistical and is trying to collect you, yoriichi will be a mood.

"My wife and child?", Yoriichi fervently whispered tauntingly,"Your daughter..."

how muzan would react to his darling being the sister of yoriichi headcannons:

𓂅Muzan would most likely find out about you due to Kokushibo.

𓂅Unlike your other brother, you are close to yoriichi due to the lack of jealousy.

𓂅Your personality is relatively close to your twin (yoriichi), however you would be a lot more chatty.

𓂅When Muzan finds out about you, he sends demons to spy on you. He wants yoriichi to pay.

𓂅Muzan would sometimes personally stalk you, and to find you with yoriichi having tea would frighten/anger him.

𓂅He wanted you to himself, you were his not your brothers. Kokushibo however was loyal to you and pretend that he didn't know a lot about you.

𓂅If Muzan did kidnap you (99% he will) then he would most likely mock yoriichi first by leaving a note.

𓂅You would immediately be made into Mrs.Kibutsuji, and Muzan's obsession would worsen over you.

𓂅So when you see Kokushibo, you would be pissed off but overtime due to a forgiving nature begin talking to him.

𓂅Kokushibo and you have a lot more in common than initially thought, meanwhile yoriichi would become slightly mental.

𓂅He blames himself for Muzan taking you and will try to hunt the demon king down.

𓂅Muzan will slowly upon up to you and will turn you into a demon, sometimes even letting you explore around.

𓂅Throughout the whole abduction, Muzan teasingly updated Yoriichi whilst spending time with you.

𓂅The narcasstic charms his way into your arms and will make sure your twin suffers greatly.

𓂅If yoriichi is ever able to get you back, Muzan would be furious yet unable to do anything yet wait for him to weaken...

yandere muzan headcannons with a male kamado reader:

𓂅You are the friend of yoriichi and a descendant of the Kamado line of heritage. 𓂅Muzan had met you when battling yoriichi, at first his obsession with you started as an act of revenge against yoriichi

𓂅However soon, Muzan had became lovesick often disguising to encounter you. 𓂅When the reader (you) is kidnapped, they are quite surprised yet realised that attempting to escape is a death wish.

𓂅The only threat against Muzan you have is yoriichi, the man is absolutely terrified of your friend.

𓂅Muzan spoils you to try and gain your affection, but you would be extremely humbled and not accept any of the gifts.

𓂅After a while, Stockholm syndrome begins, your loyalty slowly drifts to The demon king.

𓂅Meanwhile, the Kamado family tree is growing on both sides. You have probably had a child with female Muzan.

𓂅Don't every try putting up a fight against Muzan, he'll end your little tantrum and quickly.

𓂅If you attempt an escape plan, then your kidnapper would likely snap your legs into half.

𓂅Skipping four hundred years, Muzan had taken you out of infinity castle as a treat.

𓂅Instead of Rei, you would be there with your own child and Muzan would be in female form.

𓂅You were surprised to see a young teenager touch your husband/wife's shoulder, he had looked exactly like your father and brother.

𓂅Tanjirō is even more shocked, a man like you was in the tales his father used to tell him about. A story about his ancestry...

𓂅Due to Stockholm, you would act polite in public areas and not say anything, only allowing a faint outline of a smile on your features.

𓂅You were the one to gently tell the boy he must be mistaken, whilst Muzan scratched a man and the two of you took the opportunity to escape.

𓂅Sadly, your significant other will never let you leave again and your great-great-great-great-great-great-great-great nephew will make it to life mission to find out about you...
