Kokushibo / Michikatsu Tsugikuni - SFW & NSFW Headcanons

[Note: Relationship Headcanons of Kokushibo/Michikatsu Tsugikuni from Demon Slayer. In this scenario, Reader will be described as a Demon Slayer with the rank "Kinoe." Will contain NSFW and manga spoilers so minors/anime-onlys, please do not interact.]

SFW:

You first encountered the Upper Rank demon on a mission in a semi-isolated village. Perfect. Just great. Your first mission as a newly ranked Kinoe has branded you with the luck of encountering an Upper Kizuki. Upper Moon One, to be exact. Despite feeling the immense pressure from his aura, you unsheathed your [color of choice] sword and muttered the first form of your breathing style. While you were preparing to attack, Kokushibo took the time to study you (more like check out). With those six eyes holding the ability to "see through," he analyzes the muscles and bones within your body, determining your skill level. A clashing of blades rang into the air, indicating the beginning of the battle.

After several hours of endless fighting, you found yourself on one knee, clutching your bloodied arm. Sweat and crimson decorated your skin, while the Upper Rank was devoid of any wounds. Kokushibo's three sets of eyes stared down at your figure, taking in your appearance. Your expertise with the sword was highly impressive.

“Your abilities are quite... exceptional. It's a shame that your humanity... holds you back. Become a demon... increase your power.”

You looked at the demon like he had two heads. Become a demon? What the hell was he talking about?? Picking up your sword, you go to attack him, but Kokushibo knocked you out and vanished. Normally, he would've killed you, but there was something about you that... intrigued him. He hadn't felt that rushing excitement of battle in quite a long time. Not since Upper Moon 3's attempt to snatch his rank.

The days that followed were full of restlessness and heckling thoughts of one another. Neither of you could focus on your missions or training. Ever since you both clashed, Kokushibo has been wanting to fight you once again, which is a rarity for the 6'3" creature. And what better way than to seek you out and crash one of your missions?

To say you were bamboozled would be an understatement. You never thought you would see him again. Your swords meet each other a few seconds later, Kokushibo staring down at your figure. He begins speaking, telling you that, “Our battle has been... on my mind for some time... now. I wish to know... more about you...”

Since then, you and your new companion would meet in the same spot and train with one another. Kokushibo gave you tips on how to improve your swordsmanship while you taught him about humanity some. A friendship eventually blossomed, and your training sessions soon became friendly outings. A mututal respect between demon and slayer was slowly brewing up to be something more.

Over time, Kokushibo had taken a great liking to you. Your skills and heart made him feel.... good. You felt the same for him. Even with his peculiar features, the demon was very attractive. He made you stronger, better.... wanted. Both of you craved the other, but your occupations made it nearly impossible. But who's to say fate can decide that?

You wrote Kokushibo a letter, asking him to meet you at an abandoned cabin. When he arrived, you both stood there, facing each other in silence. You finally swallowed your nervousness and spilled your heart out to him. After your confession, the Upper Moon continued to stay quiet until his deep voice spoke up. “Despite working for... the enemy... you have made my cold heart... beat again. Even with your humanity... you are special... to me.”

At the start of the relationship, physical touch was mainly initiated by you. Kokushibo didn't really think much of it, but his way of showing you his love was through quality time. Whether it be watching over you in the shadows or napping with you during the day, he was happy to be in your prescence.

Ultimately, he told you about his past with Yoriichi. How it shaped him to become a demon. That night was the first time he initiated physical affection and gave you the sweetest first kiss known to man (and of course, you returned the favor by pecking every space on his marks).

NSFW:

Kokushibo does have experience when it comes to sex. Even though he had a wife and kids as a human, it'd been years since he's been intimate with anyone. So the first time ya'll get down, he takes things slowly before getting into his groove.

Laid upon the soft futon in your bedroom, the Upper Rank's large hands roamed your body while his lips softly explored your neck. He sensually removes your kimono and delivers open-mouthed kisses on your chest. You lean your head back to allow him full access to your neck, a delicate moan leaving your lips. Taking it as a sign to further his actions, Kokushibo kisses a trail down your stomach, the top row of his eyes watching your reaction.

You appreciated how gentle your six-eyed boyfriend was with you, but your impatience was starting to show. Sensing this, the Upper Moon leaned away from your covered cunt and gave you a tender kiss. “I suppose you shall receive... your award for your... patience.” As soon as he says this, he makes his way back to your pussy, removing your underwear and goes to town. You had never felt such pleasure in your life (you damn near passed out).

Afterward, he licked your essence from his lips and chin and stood on his knees, removing his clothing. What you saw made you and your pussy nervous. Kokushibo was a good eight inches flaccid, but a full nine when hard. There was even a prominent vein on the left side of his cock.

Relishing in your reaction, he picked up your thighs and reassured you softly, and slid in. He may have ate your cunt like a pro, but he pounded your cervix like a full-blown champ. You were amazed that his cock could reach your womb before even started moving.

I see Kokushibo as a firm type of lover. He'll whisper sweet and loving words at you while bullying your G-spot like it did something to him. He also took notice of how you'd clench around him whenever his deep voice dropped an octave (he took advantage of this fact every single time). Kokushibo may have been a gentleman, but he showcased just how much of a demon he was in the bedroom.

“You can give me... one more, can't you...? Don't hide yourself from me... let me take care of her needs...”

[These took me way too long to finish💀. I hope I didn't make his character OOC or anything of the sort. ^^']

[ketsuyuki-hibana-typed]

It may be strange request, but...Could you make headcanons about Kyoujuro and his "future wife" when they were children. When Ruka was still alive, when Shinjurou was a Pillar?

Rengoku Kyoujurou x FutureWife!Reader

When Shinjurou came back with other human that hide behind him, little 10 years old Rengoku Kyoujurou become curious.

He jumped around that tiny human, you, who gripped Shinjurou's haori, timidly peeked up from where you stood.

"Father, who is that?"

"Ah, I haven't introduce you yet. I saved her when I was in mission."

Kyoujurou became more excited, he suddenly grabbed your hand and said, "I'm Kyoujurou! And you?"

"Hey, it's not polite to ask her out of blue like that." His father sighed. "She has been live for a long time inside the forest. She has minimum wordings. Right, (y/n)?"

You nodded, but then open your mouth

"I'm (y/n)."

Kyoujurou's face brightened. The thought of he now has sister was flooding on his head.

Kyoujurou learned that you're once was originally planned to be a sacrifice of the demons. These demons were said that they will not devour the villagers unless they give children as sacrifices every month.

The place where you born was like a camp, basically human farm. You only given with name and birthdate, not knowing who your parents is.

Until you somehow, managed to escape into the forest when they accidentally loosened the door when they're about to deliver you and the other children to the demons.

You learned human language from a rich family that live near the forest, but you quietly heard them talking without showing yourself.

And the rest of the story is survival. Hunting, making traps, stealing swords, making house. All of them was made by yourself.

Until one day, the trap you set was failed to capture the demon. Shinjurou saved you, and brought you here.

Well, actually Shinjurou was amazed by your skill, considering you're the same age as Kyoujurou and thought that potential will be a waste if he left you there (Also, a reminder that a little girl was alone inside the forest all this long time)

Ruka accepted you here, so does Shinjurou. Kyoujurou and Senjurou didn't mind either.

That's where your real life started.

You learned how to speak and act properly from Ruka. Both you and Kyoujurou were practicing together on the swordsmanship.

You learned how to feel from this family

Kyoujurou loved to take evening stroll while holding your hand after practices. He said that your hands are so warm, he thinks he could hold onto them forever.

"You know, (y/n). I think you have this- uh- this-! I don't know how to tell it, but you have this kind of aura, but I cannot describe it."

"Charm?"

"Yes, that's what Mother told me, charm!"

"No, I don't have any."

"You have! And only me who could feel them!"

Lived in the middle of upper class family probably the real definition of real wealth. But apparently not you as an Rengoku outsider. The boys and girls that has same age as you often bully or tattling you.

Kyoujurou becomes furious when he found out, and fight them, even though you always ended up saving him.

"I told you that I'm fine, I didn't take their talks with my heart." You pressed compress onto Kyoujurou's temple. He groaned in pain. "What will Ruka-sama say if she saw you like this? I should be the one who protected you."

"I- I should be the one who protect you! I'm the big bro!"

"Yes." You finished with the treatment. "And I'm indebted because Rengoku family has taken care of me, and I shall pay them back to guard their descendants."

"Wha- That's nonsense! You're our part of family!!"

You didn't listen to him anymore and walked away.

After that incident, Kyoujurou still considered you as his sister, but he never talked about your obligations to protect Rengoku.

Shinjurou always brought you gifts after missions even though he's kind of sucks on it.

"You bought her... sculpture."

"Yeah, any human being in this world like sculpture." Ruka looked at Shinjurou in disbelief.

"(y/n), I will buy you hairpin tomorrow, ok? You could threw that into trash pile or burn it down along with the leaves at he yard."

"Okaa-sama, it- it's okay! Otou-sama was right, no one in this world didn't like sculpture."

"You don't need to cheer him up."

"Ruka, you're so cold."

When Ruka was sick, you took the lead of house chores.

"I'm sorry that I burdened the tasks to you."

You helped Ruka sat down on her futon. Senjurou was peacefully sleeping on her side while Kyoujurou sat with folded feet, listened to his mother.

"Okaa-sama." You bowed. "I've pledged to serve Rengoku family. I will not disappoint you."

"You are one of my children." She let the most tender smile you ever saw in your life. "I never considered you as our guard, so does Shinjurou. You are our daughter. Come here."

You came closer to her. She hugged you into her chest, caressed your hair slowly.

This is what mother's kindness felt like, dissipates into your every well-being. It's warm and soft.

You really wished that Ruka could have longer age.

But everything was changed with quick pace when Ruka finally left this world.

On that day, you felt what sadness is, how it felt like when you holding Ruka's board name in front of the house, seeing people saying 'I'm so sorry for your lost' for many times until you became a little qualm.

But none of nags were spat out from your mouth, not even tears sheds out. You just felt sad, that's it.

Senjurou never stopped crying and Kyoujurou tried to calm his little brother. You had to step out.

"Kyoujurou, let me handle this." You told someone to hold the board, replacing you. You brought Senjurou onto your embrace, cradling him into your arms.

"Senjurou, it's okay. I'm here, Ruka-sama always been here too. She goes to yomi but her heart will always be inside us." You closed your eyes, patted Senjurou's back, wiped his tears until he fell asleep because of exhaustion.

You noticed that Kyoujurou looked at his little brother with empty eyes. You smiled towards him, opening one of your arms.

"Come here, Kyoujurou."

He trembled, slowly moved towards you.

Until he breaks down and cries his heart content out on your shoulder. You don't know how many hours you've spent, sat down there while soothing both of them simultaneously.

On that day, you swore that you will fully protect this family with your soul and body.

After that day, Shinjurou never let anyone, even his children stepped onto his room

Except you, because you managed to 'forced unconsciously" onto his guard. He only let you sat on his engawa room, talking light conversation while drinking tea and snacking.

Both you and Kyoujurou took Final Test together and become demon slayer. It didn't took him so long to be a Pillar while you're still a Kinoe.

You knew how Shinjurou reacted to Kyoujurou for being a Pillar. It really hurts you when you realized how much he changed towards this family.

But you're trying, you never give up to make this family whole again, even though it might not be the same as Ruka did.

So, that day, you asked if he could spare his time for evening stroll like you always did when you were still children.

He happily accepted your request.

Both of you stopped at grilled sweet potatoes booth, taking rest.

"Congratulations on being a Pillar." You gave him flame-motive cape. "This was Otou-sama cape, but it worn out. So i fixed it first."

He looked surprised and freeze.

"Um, it's okay of you don't like it. I know it looked-"

"NO! I WILL USE THIS!"

He wore it on his back, spinned like children testing their new clothes.

"Umu! This is great!"

"It's good to hear." You let out relieved sigh. "And-"

He sat down again, ready to hear your next words.

"Otou-sama.... Didn't mean it when he said he didn't care about you. I know that he's happy."

"It's okay! Father is always like that after all! I just had to-"

"I really mean it." You looked at him straight at his eyes with tender gaze. You reached your hand to his head, patting it. "Thank you for your hard work, Kyoujurou."

He stunned again.

It was like something snapping from inside his mind. His tears suddenly flows without warning.

You grabbed him onto your embrace, letting him cry.

You knew it's hard. It's hard for being cheerful 24/7 because he didn't want to make anyone worry.

After that, he became really close more than ever. He didn't like being called with Flame Pillar. Just call him with usual name.

Uzui realized your talent as trap maker and took you as his tsuguko, even though your breathing traits are Flame.

Kyoujurou wasn't so happy with this decision.

"I became a Pillar because I wanted to make her as my tsuguko."

"You've just BECOME a Pillar." Uzui snickered. "Don't be so cocky."

He didn't talk to Uzui until you scolded him for doing so.

Everyone was wondering why are you still not 'chasing' Kyoujurou. You made your own breath, and talented on almost everything but people just wondering why you couldn't caught up to Kyoujurou.

You never interested to become one, you only focused on rescuing orphaned children, took them into your care. The corps made orphanage for children who lost their family, and you're the one who trusted by Oyakata-sama to lead it because you could handle kids.

You're the one who brought him when he injured on demon train mission. You're the one who took care of him when he's still in comma.

When he woke up and found you holding his hand, that's when the feelings towards you changed, from a sister, to someone that should have Rengoku name as their family name.

"If you really love her, then when will you confess to her, headass. You've retired like me, but she hasn't. Who knows who she paired with while she's in mission?"

"..."

"She didn't want to be Flame Pillar even though Oyakata-sama asked her to be one after your retirement. And you know what she answered? 'I'm not a Rengoku, so I don't have obligation to take that role.' Damn, man, stubborn girl as always.

"Shut up for awhile, will you?"

"Or you wanted someone to propose to her first? Don't you know that she's popular amongst the Kinoes, even other demon slayers? She's caring, kind, good with children and strong too."

"I'll kill the-"

"Wow, keep that killing intention to yourself. The only reason why people who put their heart onto her weren't confessed yet because they knew you will rampage, knowing you as her closest related person."

Kyoujurou crosses his arms, his mind was a mess, thinking on how he could propose to you without being awkward and to avoid the dense inside your head, because you only believe that all you had to do until the rest of your life is serve and protect the Rengokus.

LIKE, LET ME LOVE YOU, LET ME FUCKING LOVE YOU WITHOUT THINKING BEING MY BODYGUARD 25/8

That's what he wanted to scream.

But he just played it cool.

Until he can't take it, or couldn't find better way to propose, so he just screamed from his top of the lung, "(y/n), PLEASE BE MY WIFE! I DON'T WANT YOU TO BE MY BODYGUARD OR CARETAKER, I WANT YOU TO BE MY WIFE! I LOVE YOU! I! LOVE! YOU!"

...he screams from outside the orphanage while you're still taking care the children.

They were giggling, teasing you when you flushed with red. His message was loud and clear this time.

And, that's how you got married.

"It's unfair because you almost knew all of me." Both of you sat down at engawa, looking at your 5 children playing around.

"We've been together for years, what are you expecting?" You let small giggle. His heart was thumped once before quickly averting his gaze to another direction. "Hm? What's wrong?"

He sighed, turning his head again and looking at your bloated stomach, ready for 6th child. He caressed it, hoping that everything going smoothly this time too. He flashed a quick smile, before kissed your temple

"It's been years and I still can't resist your charm."
