Muzan's Treasure Kanon58

Summary: Muzan takes over the Demon Slayer corps, he had one goal. To have them find a cure to the sleeping Kamado Tanjiro. His dearest human. ONE-SHOT.

Note: its a AU where Muzan enslaves the pillars and ironically keeping a human being instead of turning Tanjiro to a demon. So Tanjiro here is not that brave based on how he would have chicken out if Giyuu did not scold him episode 1. Meaning he doesnt fight against Muzan as much as he would have if he was trained to be a demon slayer XP. Also in here Muzan cared for his life,and this is always based on cap sudden care of Muzan about Tanjiro being dead always gets me when he 'cared' for once xD

What a straaaange thing Muzan-sama 👀

Also this is just a dream I had, so the ending maybe made no sense but...I hope you enjoy the Muzan x Tanjiro fanfics I made!

WARNING: possible abuse. ANd obviously Muzanjiro Bloody Bed Scenes As always lol. Only sadistic readers will be okay with it like me- YOU HAVE BEEN WARNED/IF DISLIKE NO REPORT PLZ!

Enjoy!

...

It was so sudden that the life of Ubuyashiki Kagaya ended when the demon king and his upper moons transported them all to the Infinity fortress.

Highly dis-advantage, it was the moment the pillar knew...

'We lost.'

The one who is mostly in pain of this is Kochou Shinobu. Because...

'We couldn't save Oyakatta-sama, not even ourselves.'

It has been maybe for eternity since they saw the sunlight.

'Were forever trapped and enslaved by Kibutsuji in this infinity fortress.'

If there is any good news, at the very least the demon Douma is dead. However...

'I guess...it was not that bad except...' Shinobu is thankfully assigned as a personal doctor of...well not the demon lord himself, but a certain human boy named...

"Kamado Tanjiro huh."

Here, at the master's bedroom lies a red headed boy with long hair is in a deep sleep. He wears some hanafuda earrings and is wearing a green and black checkered haori while inside is a red kimono that obviously was not the boy's size but the man's size of clothing. At first Shinobu thought it is also a demon, maybe a heir or something due to the fact this person is sleeping inside Muzan's quarters.

But the moment she touched him.

"He is a human, this boy is a real human being."

But why?

It disturbs her and so are the remaining surviving pillars.

Giyuu
Mitsuri
Kyoujiro
Uzui
Obanai
Muichiro
And Sanemi

Unfortunately Gyomei died when he protected Kagaya's son. He succeeded in saving the remaining three little Kagaya children in exchange of his life.

"This doesn't make sense." Shinobu is angry. "Why does...why does a human being is being cared for by the devil himself?!" She questioned the sleeping boy. "Who on earth are you to be this lucky?"

Is it really lucky?

Yes he is lucky. This Tanjiro kid is very lucky, you know why? "After all...everyone of us sharing our blood just not to be eaten, especially Shinazugawa-san!" Upon being trapped here, sometimes the demons and even upper moon like Akaza would check on Tanjiro's condition.

As if...as if he is also a master of this place despite doing nothing but stay in bed unmoving but still breathing.

'Nobody attempted to eat him nor taste his blood. Unlike us...and..specially...!'

Yep, Shinazugawa Sanemi is pitiful. He got more torture than the rest. The demons will feast on him because he is a Marechi. So delicious! Even Muzan joins the fun of tormenting the ex-Wind pillar.

Yet this Tanjiro, whoever he is and for whatever reason he is cared for by Muzan.

In an extent of...

"Hey you, Insect pillar." Shinobu glared when everyone is forced to kneel down to his presence. "I heard you were a doctor like Tamayo." Everyone perk their heads, why does that matter? Then they heard him.

"Become my personal doctor." Muzan ordered.

Giyuu speak out his thoughts by accident. "Kibutsuji-sama why would you-" Muzan ignored him and corrected. "No, become the personal care taker of Tanjiro."

Confused.

'Tanjiro...? Whose that?' Every pillar looks at their eyes to communicate.

To Shinobu's shock, when she had no choice and said yes...quickly Muzan lead her to his room to show the most gentle face ever.

"Wake him up."

It was direct.

"P-pardon me Kibutsuji-san?" Shinobu rolled her tongue with fake smile, yes a very forced smile. "I mean...Kibutsuji...sama-" Muzan didn't care much though and continued his instructions. "If you can wake him up, I will set you free and the rest of you pillars."

Astonished.

"I don't care what method you will use. Just wake him up." Muzan approached Tanjiro whose totally unconcious. Gently his pale hands with long demonic nails as you can tell, fix the hair strands of the red haired.

'It was shocking.' Shinobu stared baffled. 'The face Kibutsuji Muzan made upon greeting the sleeping boy...'

Muzan leans forward to Tanjiro's big forehead that had a scar on it.

His eyes looked like he was precious to him.

'What the hell is this?'

Muzan even said, "Sweet dreams Tanjiro-kun." And kissed it. He kisses the freaking forehead of this Tanjiro!

Shinobu eyes gawks. 'Is this for real?!'

The fact witnessing this heartless demon lord actually loves someone.

What more-

"S-sorry to even ask but!" Shinobu couldn't shut her mouth. "What is your relationship with him? I mean...isn't he a human?!" She wants to deny it but then, with no embarassment nor anger.

Muzan shared to her the truth. "This boy named Kamado Tanjiro, I slaughtered his family and eat his sister who I turned into a demon." Muzan sitting beside the sleeping figure of Tanjiro, his hands from the boy's hair earlier travelled down to the battered and beaten hands of his that rested upon his stomach like sleeping beauty would look like. "The shock of loosing his family put him to comatose. It was not my intention to break him..."

There was no sadness nor guilt displayed on Muzan's face but his eyes did feel lonely.

Shinobu thinks this is crazy. "T-then why are you keeping him alive if he is already useless to you...?"

'Oops, I used the wrong word!' Shinobu thought it would offend the monster but then the man answered back without any second thoughts. "Because I love him." Muzan even smiled as his fingers intertwines to Tanjiro's small human hands. "He is the sun I had been searching for." Then he frowns, "But I took that away by accident. I thought to just threaten him and force him to be mine but...he and his family is so protective. I got pissed off and this is the result."

Shinobu needs medicine. 'I think am sick of this reality!'

Either way she doesn't have a choice does she?

"F-fine. I will do my best to find a cure for him. However what proof do I get that you will keep your words that you will set us free?"

It is time for negotiation of course!

Muzan finally looked back at Shinobu as he keep being obsessed to stare at Tanjiro's face and body in his bed looking so peaceful.
"If Tanjiro-kun wakes up,I'm sure he would wish you all free." Muzan said with no lie. "This time, I will make him like me by making his wish come true."

Shinobu is so done with this.

"Unbelievable." With no reserve,Shinobu was frank. "If you were actually capable of such emotion, this thing called 'love'..." she fist on her haori. "THEN WHY DID YOU MADE SO MANY DEMONS THAT EATS OUR FAMILY AND KILLS THEM WITHOUT MERCY!?" She points at Tanjiro, "IT IS THE SAME FOR THIS BOY! YOU...YOU KILLED HIS FAMILY YET YOU DARE TO SAY YOU LOVED HIM?! AND THEN WHAT...? YOU THINK BY DOING THIS WILL REDEEM YOUR SINS!?"

Shinobu exclaims.

Muzan looks bored though.

"You can't blame me."
"Eh?"

Muzan stood up, Shinobu made a defense stance as she thought Muzan will punish her for screaming like that.

Like, she had no place to do that as a captive right?

Everyone's lives are on the line not just her after all.

Stiff, Muzan pat her shoulder. "Blame the fact it took so long for Tanjiro to be born."

He smirks and dismissed himself.

"Now do your job insect pillar." With small threat. "An insect like you is so easy to squish."

The door shuts when a string plays.

Shinobu exhales her trembling body when the demon king touched her so easily.

"He could have killed me but...but he did not.." frustrated for being weak, Shinobu cries. "Dammit!" Slamming her angry fist at the tatami. She looks up to the victorian bed where laid the so called 'loved' by Muzan. "Hurry and wake up boy, I can't keep up with this nonsense...!"

---

3 days later...

'I'm sure people wonder why we had not killed ourselves.'

Shinobu mixing potions to determine Tanjiro's real cause of comma. 'We couldn't kill ourselves.' Shinobu remembered Ubuyashiki Kiriya's order the son and heir of Kagaya. The boy shouted while crying with strong will.

(("Come back to serve me Hashira's! Live on! Live on and avenge my father! No matter what!"))

'Which is why we...the remaining living pillar decided to comply for now. But normally we would have sepukku if were just gonna be a demon's minion. Though...'

Glancing at the mysterious sleeping boy Tanjiro in thar comfy luxurious bed in Taisho Era. 'Kibutsuji has never laid a single torture against us except Shinazugawa.'

Well, to be honest it is kinda Sanemi's fault. He was violent, noisy and always protesting.

'It is normal to be disgusted when you are a gourmet prize in demons.' Shinobu pitied Sanemi but Sanemi growled at them and said.

(("IF YOU GUYS HAVE FUCKING ENOUGH TIME TO WATCH ME GET HUMILIATED, HURRY AND AVENGE OYAKATTA SAMA IDIOTS!"))

Sanemi has not given up. Therefore nobody else had rights to give up.

Knock, knock.

Shinobu stops working her fingers on the medicine bottles and looks at the japanese sliding door opens. Revealing..."It's me, Tomioka Giyuu. Am entering the premises Kochou."

Shinobu smiles, she was relieve to see Giyuu safe but Giyuu would never notice that she actually cared so much. "Ara, Tomioka-san...please do come inside." On Giyuu's hand were a tray of food and his feet had...

Cling...clang...

Chains.

Shinobu cannot help but make a face of worry and resentment. 'We are indeed Kibutsuji's prisoners by the end of the day.'

Giyuu then carefully made his way to Shinobu's desk granted by Muzan for her to use.

"Who is this?" Giyuu of course will ask Tanjiro's presence at the bed. Shinobu chuckles, "Shocking right?" She then glared at the figure. "Kibutsuji Muzan apparently keeping this boy named Kamado Tanjiro captive until he went to a comma. Is what I get the gist of it."

Listening, Giyuu cannot stop his free hands to touch Tanjiro's flesh. "He is warm...?" It was a dumb question. Of course he is alive! "I just said he is in comma. This is why nobody likes you Tomioka-san~"

Giyuu tsukkomi with no emotion. "I'm not dislike by anyone." Then his eyes landed to the weird scar on Tanjiro's forehead. "Isn't this what I think...?" He spoke his thoughts.

Shinobu who has absolutely no idea, stood up from her sit to join Giyuu checking on Tanjiro. "What do you mean Tomioka-san? To be honest I had not done a physical check up yet." Somehow Shinobu felt scared on touching Tanjiro carelessy, since he seem to be so important to Muzan.

Without a nichirin blade it is terrifying.

Giyuu point at Tanjiro's red mark in forehead then points at his own cheeks. "Remember the fight against the demon who killed Kanae? Douma was it? A strange mark appeared on my left cheek you said." It clicks now, Shinobu gasps. "Noway, this boy has a demon slayer mark too?!" Shinobu is envious a bit. 'I'm so weak that a demon slayer mark never appeared on me...!' Although that was for the better! Because with a mark like die you will die early.

Shinobu decided to softly touch the demon slayer mark on Tanjiro's and eventually her finger tips reaches the hanafuda earrings. Shinobu commented, "What a peculiar boy this Tanjiro-kun. Being loved by the demon king, having a strange hanafuda earrings and a surprisingly demon slayer mark..." she sighs, Giyuu looks at her. "Who is he to be making me so curious?"

Giyuu agreed. "Me too, if he woke up we can ask him." Shinobu doubted that idea. "You mean, if he will actually wake up." Shinobu talks about reality. "Some people in comma takes years..." it reminds her. "Oh, I should have ask when did he fell to comma to determine the chances of him waking up."

However Giyuu pointed out. "Meaning you have to ask Kibutsuji Muzan the day this boy collapse?" Shinobu had sweatdrops. "Yeah." Because who the hell can ask the scary devil lord about a personal thing!?

'But he is the one said it doesn't matter what method as long as it can wake up Tanjiro boy!'

Giyuu deadpans. "Goodluck."
Shinobu smiles wider with vein pop. "Ara~ara Tomioka-san, in times of these you are suppose to volunteer!"

---

Later that day...

"Why are you asking me that?" Is the immediate response of Muzan sitting at a king sized chair. Shinobu and Giyuu went to the throne room of infinity fortress. This is where Muzan will spend his time sitting and just staying still while closed eyes.
At first they thought he is sleeping, but it turns out his eyes were closed because he was reviewing the memories and seen through the eyes of the lower demons he created.

Basically he is scanning through all his demon reports linked to their mind.

He can see to their visions and memories. That is why Kibutsuji Muzan focuses onto when sitting at his throne while his upper moon either watches him or spread outside eating and hunting pillars.

Giyuu helps Shinobu explain. "Pardon for interrupting Kibutsuji-sama, this is for Kochou's research. She said to determine the possibility of that human boy waking up is the reason of his comma and how long it is since." Shinobu's eyes were widen as both of them kneeling before Muzan like how they do to Kagaya.

At first they couldn't tolerate it. But somehow, the eagerness to survive and to eventually escape is there.

Which is why they abide.

Muzan stared at them speculating and suspicion but he found none. "Very well." Both were surprise that Muzan can easily be converse on negotation. Probabbly because he lived so long, he can tell if they were making it up or frankly trying so hard not to be killed.

Muzan confessed. "Since winter...hmm, let us see..." Muzan contemplates and shared. "Out in the mountains he is 13yrs old. I took him out during winter. My Tanjiro is still awake along with his demon sister Kamado Nezuko." Shinobu and Giyuu paid sudden interest.

The name 'demon sister'. The fact how no shame Muzan nonchantly say it, it is somehow vexing even though they do not know who exactly is the Kamado Clan. It was pitiful story.

"It was atleast 2 years after...I finally decided to devour his stupid useless little sister." Muzan rolled his eyes. "He pathetically broke down and there." Shinobu and Giyuu almost twitch how insulting Muzan said it that way. 'I thought Tanjiro boy is important to him! Why would he call him pathetic and...and...!'

Shinobu is angry and so is Giyuu, but they hide the bloodlust by baring to hear the rest. "Now he is 15years old, so I guess he had been asleep for 6 months already." Muzan finishes.

Shinobu cleared her throat and showed her usual fake smile. "Aahh~ I see, I see. So it has not been that long! If so please allow me to do body check up on him to learn more how to wake him up~!" Giyuu felt disgust at the most fake Shinobu voice ever. 'But she is doing the right thing...' Giyuu understands, it cannot be helped.

Muzan just looks at her and dismisses her. "Alright, I give you permission. Now both of you go." Giyuu and Shinobu bows. "Thank you very much Kibutsuji Muzan-sama."

And so...!

FLIPS!

Shinobu lifts up the sheets that has been covering Tanjiro's body. Giyuu is not allowed to see Tanjiro naked according to Muzan. Apparently he is easily jealous and possessive that no other men shall see his beloved naked.

Everyone is of course disgusted by a 900 years old demon like a little child!

'Here goes nothing...!' Determined to unlock the key of mystery surrounding Kamado Tanjiro, Shinobu carefully undresses the boy. It is normal for her to see naked people because she is a doctor and a nurse. However, Shinobu would never thought she will tremble at the sight upon seeing Tanjiro's bare body.

BADUMP!

"What the hell are these wounds...?!" Tanjiro had a lot of weird bruises. "Could it be...?" When she touches them, it is confirmed. "Kisses that are actually bite...marks." that bastard had been marking his property!

Shinobu wants to puke. "How sickening. Love my ass...!" Then she also notice some bite marks on the sleeping body. Shinobu gulps as she felt anxious upon realizing what this human went through the hands of a toxic love from the demon lord. "He is...feasting his blood."

She was wrong about Sanemi and them are getting their blood taken.

Even Muzan's treasure is under the same fate!

Eyes glued to examine Tanjiro's sleeping mode, Shinobu finally notice something crucial.

Her trained fingertips checking up the boy's vein and bones besides the physical chest.

She found something she would never thought.

"Huh?" Shinobu doubted at first but the more her hands travelled from Tanjiro's neck, ribs, hips and legs.

It was something made her feel sorrowful.

"His legs are broken...?" That just meant this boy can't run and walk. It was un settling. 'Did Kibutsuji made him cripple in order not to escape or is he originally cripple?' Never the less, Shinobu decided to patch up Tanjiro's legs to go back to normal by bandaging both sides. "What a very unfortunate boy you are Kamado Tanjiro-kun." Somehow Shinobu decided to be closer. "Tanjiro-kun." She says, "I will make sure you will wake up and then..." smiling. "We will avenge your family."

Pulling a knot.

"It's a promise from I the Insect Pillar of demon slayer corps..."

For now she decided to dis infect the wounds that spread's all over Tanjiro's body even the nasty kiss marks that obviously done by the self proclaimed lover Muzan.

...

---

After cleaning Tanjiro's body, suddenly the door opened.

"Tanjiro!"

Shinobu snaps her head behind as she heard that voice belong to. 'K-Kibutsuji Muzan?!'

Muzan spot Shinobu in a perfect timing of dressing back Tanjiro's clothes. By the looks of it, Muzan seemed to behalf asleep. His eyes went clear when he realized that his Tanjiro is still at the bed. Their bed. Noticing Muzan is inhis padjamas, a very elegant color black sleeping kimono's with his silky dark hair.

"U-um-" Before Shinobu can question, Muzan passes by her vision and he went to embrace Tanjiro. "I'm glad you are still with me..." is what he whimper.

Shinobu is star struck. 'Such a broken voice he is capable of...?' Distancing herself as Muzan did not even acknowledge her presence, Shinobu awed upon what she heard and witness. Like again...it was insulting.

Muzan hugs Tanjiro so tight as he let out those desperate and lonely words. "Don't ever leave me be Tanjiro..."

Badump...)))

'I don't know.' Shinobu grits her teeth and clutches her haori like deja vu. 'My heart just hurt the way he says and shows it...' it is truly unfair. 'To think he even dare to beg such happiness not to be left alone...!'

Muzan who did not care of her bloodlust, proceeds to lay down Tanjiro's head at the pillow. "You are somewhat cold." He chuckles and then..."Let me heat you up." Muzan kisses the boy's lips hungrily.

Shinobu gawked and she let it out. "W-what are you doing!? That is sexual harassment!" Muzan explained briefly. "If I don't do this, Tanjiro-kun's blood vessels would stop moving. He need some activity that can heat him up alive." Shinobu can't stomach that logic. "There is a way to keep his blood flowing!" She scolds him. "By doing body massage and not s-se-"

Muzan smirks at her. "Ahh~ Are all pillars virgin?" He mocks, "Oh right, after all nobody lives long when they dare to defy me and my demons." Shinobu held her tongue to retort. 'Just calm down...! I must not die, if I insult him back he would kill me.' Shinobu uses her breath technique to calm her usual hot head anger.

"I cannot win against you sier." She thought she can escape by turning around, Muzan then ordered her. "Who told you to leave? Stay here and observe Tanjiro's condition Shinobu."

Badump, badump!

Shinobu felt the short terror before it became malice. 'HAaahh?!' Inside her head and outside a fake smile to decline the offer. "Kibutsuji-sama, if you and him will make love I shouldn't be here for privacy~"

Muzan narrowed his eyes. "Do not make me repeat myself." Quickly Shinobu sits at the floor like a good. "A-Affirmative."
Seeing the butterfly doctor is being obedient. Muzan now focus to Tanjiro's face. He caresess it and then. "Tanjiro...thanks for the meal." He nibble Tanjiro's lips as his hands worked to touch the unmoving body.

Shinobu went red. 'Eeeeehhh! Man to man I cannot-' seeing Muzan pulls Tanjiro's hair with love is so wicked enough!

'Gaaaah!'

Shinobu raises her hands and covered her eyes.

Muzan scolds her. "Watch us." It was deep voice, Shinobu shakes and her fingers slowly goes apart to create a small hole to view behind hands covering her eyes.

Technically her whole face. "My a-apologies-"
Her heart is going crazy upon seeing a live sex between men. Worst part is Muzan is older and Tanjiro is just...just...

'God dammit he is 15yrs old! I want to kill this pedophile!'

"Nnh..."

Shinobu froze.

'W-whose voice is that?'

It was a very small and short whimper.

"Mmm..mm..."

No...

It was...

"...haahh..."

The moment Muzan raised the cripple legs of Tanjiro to enter there, Shinobu heard it clearly.

'T-Tanjiro is moaning in his sleep!?' Shinobu cannot believe the boy in comma is actually reacting to the hot sex his body being abused onto. 'Wait, so it was effective...!?' So Muzan's idea to keep Tanjiro's body warm is actually working but so disturbing to be exact.

"Aahh..haa..hhhaa..." Tanjiro boy is...panting and moaning but not that loud. Because his eyes were shut, his mouth is not really open, it was like he is just having a nightmare some sort. 'This is a nightmare.' Muzan thrusting himself, the bed creaks. The cripple legs of Tanjiro swaying, Tanjiro seems to feel the pain despite asleep.

'Please wake up!' Shinobu beg inside her mind as she couldn't do anything but watch Muzan violate the sleeping beauty.

"Tanjiro, Tanjiro...Tanjiro." Muzan keep calling his name with wanting while Tanjiro doing short tired whimpers and visible pang in his face, but then again his eyes couldn't open.

He was trapped to sleep.

Kochou Shinobu bare it till the climax.

Event from 3 years Ago

---

Tanjiro's POV with Outside POV

'It all started in a single breath.'

{BREATHS}

'It all started with snow flakes.'

{BREATHS}

'It began by the smell of blood.'

{SNIFF}

'I regret it with all my heart.'

{SNIFF, SNIFF}

"I smell blood...?"

Looking around the snowy scenery, young Tanjiro with ponytail up, blue scarf on his neck and an empty charcoal bag. However he was not 13 yrs old. He was 12 during this time, no scar in his skull not even earrings.

'Father started to get very ill so I needed to help mom.'

Suppose to be...yet why is there...spots of red? No, its a trail of blood! Normally you should ignore but Tanjiro couldn't ignore his gut to follow it.

"A Bear attack...?"

And begin to find himself investigating a cave where the trail ends.

Pluck, pluck.

Sound of dripping water from the cave's body rocks. Slippery it may be, Tanjiro dared to go inside. "Hello...?" His voice echoed, slowly the light is leaving his side as he goes further inside it. That is when he heard someone panting.

"Hahh...ghh...hahh...ueghhahh.." the way it was like out of breath and pain, 'Someone is wounded?' Tanjiro begin to enter the darkest side of the cave and shouts. "IS ANYONE THERE?"

Such a brave 12 year old isn't he?

He even has a hatchet with him just incase. As the eldest he has to be brave no matter what. His father taught him a lot of things before his father's health came into a surprise of very bad result of illness by becoming bedridden.

Is it poverty? Or is it because of a certain breath of fire?

"PLEASE RESPONSE? ARE YOU A HUMAN? ...?"

Nobody responded except a growl.

'Is it indeed a bear, or any other kind of injured animal?'

"Grr..."

Tanjiro thought it was some kind of animal due to a foul smell. "Am entering near!" He even bothered to ask permission.

Tap,tap,tap.

Finally Tanjiro stop on his tracks. He found the source of someone in pang and growling with anger.

There he is...

'Red eyes...?'

"E-eto...?"

'I found an injured man with a very pale skin like the snow and black hair like the dark sky. Red eyes like a lotus flower. He was very handsome and beautiful...'

Kibutsuji Muzan.

Something about this man's exotic beauty Tanjiro can't help but blush and felt like he had to make sure he is careful approaching him, 'He is...cautious of my presence.' Like a wounded animal that is and of course he is seeing it. 'There is blood at his left shoulder and around his torso? He got bear attacked? Or...maybe...' Well what if it is a criminal on the loose?

Muzan on the other hand glared at the boy with suspicion since he see a hatchet hidden on the boy's belongings. '...A kid at this place?' The sun is up actually, but thanks to the snow it look like cloudy day.

But the thing is Muzan cannot go outside with such injuries. Muzan cares about his own life and safety more than anything else. 'Good timing...This kid...I can eat him to recover!' Is the plan A...but!

"E-excuse me mister!" Tanjiro removes his blue ragged scarf and- "I can give you first aid...!" He had a cracked up smile as he offered that. Tanjiro is not sure how to not look suspicious against this strange man bloodied and hurt. He set aside the suspicion if this man is a nice human or a criminal or who knows.

'He smells weird because of the blood?' He is smelling something else but he did not know yet the existence of humans and demons so he has no idea what the other smell is. 'I need to help him. He seem to have lost lot of blood, he looks so pale...'

It is dark so he cannot tell if it was a bear slice or a katana slice. Speaking of which, swords are not allowed at Taisho Era anymore otherwise if you are a city cop. The fact the eyes were red but they still figure as human, Tanjiro did not questioned if this person is even human for real. All he can think of is when he notice how the man dislikes him...'He is glaring at me...!' For whatever reason the man is angry. Well he can smell 'dislike' but not particular against him oh...anyway...

Tanjiro raised his hands. "L-look!" And properly smiled this time by inhaling and exhaling a short moment, he look confident. "It's going to be okay."

Muzan twitches from that assurance phrase.

Something about this kid's smile felt safe.

One more thing, Tanjiro does not have yet his earrings in his ears during this season so Muzan did not know he is a descendant of the sun...the fire he hates the most.

Not yet.

Muzan stops growling, his expression from cautious to flat.

Tanjiro sighs. '...I'm glad he calmed down!' Then kneels his knees and carefully reaches Muzan.

"May I touch you?"

Badump...))

Muzan is not sure why his seven heart's beat like that.

That question sounds so cute to be honest.

The little boy actually look...'Ugly same time charming.' This brat is a adorable human being. 'He probably is not even a teenager yet.' Speculations this boy is around 12 or lower age basing on his voice, appearance of height and baby face. Without speaking, Muzan made a movement to show his wound. Tanjiro is delighted by this welcoming gesture. "Thank you!" Then moves closer.

Muzan then made an evil smirk. 'What a fool.' Behind Tanjiro his claws went out, ready to slice his prey to death and become his meal.

Only then-

Tanjiro idiotically moved too close he loose balance. "Wu-Waaah!"

BONK!

"UGH!"

Muzan and Tanjiro bumped their heads and Tanjiro's freaking skull in that said forehead is hard as a rock!

'What on earth?!' Muzan went dizzy. 'Is this kid's head made of an iron or something!?' It felt so stupid.

"I'M T-TERRIBLY S-SORRY MISTER!" Tanjiro panicked upon seeing Muzan's facial reaction from pale, went much more paler and his eyes were obviously spinning. "Are you okay mister?!"

Ah.

Tanjiro touched him in is shoulder's to keep him conscious, Muzan and him have locked eyes to each other.

Something makes them stiff and ohhh finally Tanjiro can see clearly now. His eyes adjusting to the darkness of the cave. 'His...eyes...are they human..? They looked like the shades of blood.' Is Tanjiro's thought. Meanwhile Muzan thought too, 'His eyes are like...the fire...a gentle fire.'

Tanjiro once more blushed but this time due to embarrassment of trying to help but hit their heads like that, oh boy, oh boy, how lame. 'He...looks like he had a status base on his handsome face.' Tanjiro had smell the stranger so close for contact, from foul scent of blood something like a flowery odor is also present.

'This person must be a rich guy? It does not smell like a resident of Kumotori.' Realizing he was fascinating at the stranger's profile by the looks and smell, Tanjiro immediately behave himself for being rude on staring closely.

"I-I'm sorry for s-staring!"

Muzan gave him a look.
Tanjiro waves his hands in the air, like a kid would do and he is a kid.

"I-IM GOING TO PATCH YOU FOR FIRST AID!" Is his excuse while obviously embarrassed more and more for being clumsy.

Here Muzan who is hungry ended up loosing appetite, 'What a dork.' he sighs and for now cease his flag not to reveal his true form.

"Fine." He said.

'Ah! He spoke!' Feeling a sense of achievement upon hearing that suave voice. "Thank you very much!"

And proceed to take care of him.

...

---

Muzan's POV

'He was a kid.'

"How are you feeling now mister? The doctor is far away but I can ask my family to gather to help me carry you down the mountains. If that is okay with you?" Tanjiro proposed his natural idea as any human being would actually say in this situation, Muzan is skeptical but he can tell this human is plainly a goody.

'...Yet he already had dependable ideas.'

Tanjiro smiles and introduce himself to remove the barrier between the air. "I'm Kamado Tanjiro. Am the eldest son of Kamado Tanjuro and Kie the charcoal seller in these mountains! What about you mister?"

Muzan stared at him.

'I see, he was an elder brother huh...'

Muzan thought about it if he would say his name or not, but either way he won't stay for too long here so there is no need to hide his identity. "Kibutsuji." He started, Tanjiro perk his head as he wrapped the scarf to Muzan's bloody shoulder, his torso had blood but there was no wound.

Tanjiro of course did not know the torso part have healed its own without him noticing. "Kibutsuji Muzan is my name." The man did not smile at the very least he revealed his name. Sheepishly Tanjiro smiles again. "Nice to meet you Kibutsuji-san! Hehe!"

Muzan closed his eyes as a sign of letting his tense body off guard for the boy's convenience to patch his wound. Also Muzan did not like to be called by his surname, he is quite proud of his name to be honest. "Muzan is fine." He said.

Tanjiro is hesitant but he is able to smell that it will offend the man if he defies that. "Err...O-okay." Then tried it out right away. "Muzan...san?"

Muzan really likes his own name, the reason behind this is because he lived 900 years and he always have to use fake name. No human being known him for his true name except the Demon Corps and his demons. As someone who lived so long, you would wish someone acknowledge your real existence right? That is why Muzan tells his demons to address him as Muzan-sama instead of Kibutsuj-sama. So he corrected Tanjiro with a soft glare. "You may drop the honorific...Tanjiro." Tanjiro can tell he was irritated so he abide. "O-ok sir!" Then proceed to wrap the bandage to a knot. "Err Muzan."

A few moments later as silence grow, Muzan watched how Tanjiro used his hidden bottled water to wash Muzan's wound before he finalize his blue scarf to stop the bleeding.

Muzan can heal, but he couldn't heal himself right now on some parts of his wounded body. Very limited, glad his torso healed before Tanjiro can even bother himself with it. They do not heal so easily...because the wound he got is from a nichirin blade. He was able to hurt back the demon slayer and killed it. Though the problem is, as said it hit his wound from the past. The wound Tsukiguni Yoriichi inflicted to him that never heals.

It is like...curse wound.

"You are a weird kid." He voiced out, Tanjiro stops working. "Eh?" Having a question mark face, Muzan began to speak more to point out facts. "Entering this cave alone, the trail of blood got you here right?" Tanjiro never actually thought of that, he felt dumbfounded. "W-well yes?" But Tanjiro added. "Also I smell you!"

Muzan raised an eyebrow. "Smell? Me? You serious?"

Tanjiro grins. "I have a keen of smell!"

"Hehh~ that is rare." Muzan can tell the boy did not think throughly of his actions just for the sake of wanting to help. "You could have been eaten by a bear or a demon."

Somehow that rings a bell.

"Demon...?"

But Tanjiro couldn't pinpoint what it was and when he was told. He had forgotten his grandmother said something similar! But anyway...he brushed off with laughter. "Ahaha! Demons are old folk tale Sir!" Muzan had a stoic face he was not responding.

Tanjiro felt guilty, quickly he composed himself not to offend the older guy for believing such creature exist at this kind of era. "I mean, Muzan-san..." Muzan rolled his eyes hearing again the 'san' but he decided to let it go if the boy couldn't master it right away. Tanjiro on the other hand decided to change the awkward topic.

"A-anyway! I know it was not right to follow the trail of blood. But I was worried what if one of my family member is the one been attacked by the bear or my neighbor Saburo-san in this mountain! So regardless, I will still follow the scent of blood...!" Tanjiro trying to defend his actions that could have put him in danger.

Muzan just.. just not interested anymore.

"Hn."

Tanjiro knows he must change this flow so he said positively with a warm small grin, how a child would do. "Also, if I did not do that...Muzan-san will be eaten by a bear right?"

Muzan eyes widen, "Me? Eaten?" And he ended up chuckling. "Ahaha..." Muzan is honestly finding that answer funny from a mere human.

Like...seriously this kid, as for Tanjiro tilt his head confused. 'Muzan-san seems to be not fretting about his injury though?' Tanjiro's ears went red and fell silent.

"Curious?"
"Eh?"

Muzan slowly lift his available left hand and travelled his fingers to Tanjiro's chin and lift them up. "Curious about my wound where and what it came from?" Tanjiro is still an innocent kid so he cannot figure this gesture is already invading private space. "U-uhh...?" Muzan evil smirks, "Let me tell you a secret then, since am in a good mood." Somehow that smirking face of Muzan made Tanjiro gulp.

"*Gulps.*"

Muzan looks at his eyes, Tanjiro had no choice but to stare back. 'Ahh...what strange eyes he indeed has...' hearing the next word while being hypnotize. "I was attacked." Tanjiro felt sweat drops in his forehead, he wanted to know if he was helping a criminal or not. "A-attacked by a bear?" He assumed. "No, by a human being." But Muzan did not lie. "What?" Now that makes it uneasy for him and this guy alone in a dark cave.

Badump, badump-

"TANJIROOO!")))

An old man's voice echoed loud.

"ONIICHAN! WHERE ARE YOU!?")))

'This voice...'

"ONIICHAAN!"
"IF YOU ARE THERE TANJIRO, ANSWER US!"

Tanjiro snaps out of it. "Those voices, Nezuko and Saburo-san!? But why they are looking for-"

Turning his head to the cave entrance, it is pitch black. "Eeeehh!? Its already this late?!" He can see the moon light rays but very little, so he knew it is indeed night time already.

Muzan who did not want to be found out by other human being decided to let him off the hook. "Go now before I change my mind."

Somehow Tanjiro is disappointed and tried to keep everything together. He thought it is a nice idea for Muzan. "What are you talking about? Perfect timing, I'll introduce you to them for help-"

"Leave me alone or you will regret it."

Muzan said coldly.
Tanjiro frowns.

"...But-"

Muzan avert his eyes and warned. "Kamado Tanjiro, I will spare you. Just go back to your family and forget about my existence. Okay?"

It's a puzzle but then Tanjiro just couldn't say no to that if he is pushed like this. "..." Muzan even added? "Do not tell anyone you met me. Promise me, will you?"

Tanjiro still feeling bad about leaving him.

"That's..."

Nezuko and Saburo's yell went louder and nearer.

"TANJIRO ONIICHAN?! PLEASE BE SAFE! ANSWER US...? WHERE ARE YOU?")))

"OIII TANJIRO! IF YOU ARE AROUND HERE, SHOW YOURSELF! YOU OKAY?!")))

Feeling much more terrible making his love ones wait, especially Nezuko taking effort to search like this how dangerous. As a big brother he should call it a day.

Decided to make a decision, he stood and grab his belongings except for his blue scarf wrapped around Muzan's wound. "I-I will be back tomorrow morning! Goodnight Muzan-san...!"

And dashes outside.

---

{'I should have listened...but I did not. Which is why...which is why...it is all my fault...'}

---

"Nezuko! Saburo-san!" Hearing running footstep in the snow, Nezuko and Saburo sparks in their eyes to find Tanjiro safe going towards them.

"ONIICHAN!"

Burst by angry Saburo whose hell worried.

"Tanjiro idiot! Where have you been?!" He scolds him in behalf of Nezuko whose first reaction is a heavy relief. Tanjiro shook his head in an apology gesture and averted his eyes. He is never a good liar but he tried to make a white lie now. "S-sorry. I slip my ankle then hide myself to rest. Before I know I fell asleep...!" He just couldn't say it since he made a promise to the strange man.

Nezuko can tell it is a lie and is finally angry. "Oniichan, you are not a very good liar. Tell me what happenand where exactly you had been? Sheesh! Mother and Father were so worried! After all a bear spotted early this morning walking around! It looks like it failed to hybernate...!"

Tanjiro can only smile nervously. "I-I see."

Nezuko sighs again and looks at Saburo while taking her brother's cold hands. "But am glad you are safe."

"Nezuko..."

Saburo cleared his throat and instructed the two kids. "Lets stop this conversation and head home before demons appear."

The winter wind blows.

"Demons...huh."

His eyes went upwards to stare back at the moon.

'Muzan-san said the same thing.'
...

---

At Kamado home.

SLAP!

"Tanjiro! You are the eldest and for you to be a bad influence to your siblings by not taking care of yourself is a big dismay!" Kamado Kie in rage of her son's recklessness for being gone almost 8 hours. Who wouldn't worry?

Tanjiro cups his slapped left cheek and chokes in his throat and dry lips in attempt to stop himself crying. "S-sorry mom...I was just..." Kamado Tanjuro on his futon bed, sick as he is ..he still bothered to butt in to the situation as the head of the family. "Now, now Kie. Let me do the scolding." Kie shouts at her husband despite being sick, as a mother these situations cannot be tolerates or it will be bad for her heart.

Fierce like Nezuko, "But Tanjuro! Our kid, just because he is dependable he is taking too much risks outside! He is only 12 years old..! I do not want him to be-" Tanjuro who smiles patiently like Tanjiro hushed her by saying, "Kie, The fire god will be with Tanjiro. Im sure he had his reasons to why he got so late." Looking at his visibly guilty 12 years old son. "Isn't that right Tanjiro?"

Tanjiro stutters and tried to fix his answer in order to avoid any further aggravation from his parents whose just really scared he was gone till dark. "I-Im very sorry father...I-I wont do it again...I p-promise. What I did is indeed not a good example as a big brother. I-I also made Mom and Nezuko so worried that it makes Hanako,Takeru and Shigeru even Rokuta cry...!" Kie and Tanjuro both sighs as they did felt bad for being harsh, but this must not be passed.

"Come here."

Tanjuro pat his side bed, where during Tanjiro's much younger days would lay beside him and talk about ancient stories, like the Hii No Kami Kagura dance that they celebrate every New Year's eve.

Tanjiro who knows this is a father and son discussion, obediently walk and sat beside him without a word. Eyes casted down to his own fist to his worn out clothes.

He gulps down.

"So...where did you go?"

Tanjuro stares were like arrows of interrogation. In panic Tanjiro opened his mouth to say the truth. "I saw-"

But then,

---

{{"Do not tell anyone you met me. Promise me will you?"}}

---

Tanjiro recalled the promise he made with Muzan guy.

Quickly he back out like a kitten and murmur. "...S-saw..." heart beating so fast as a guilty person. Tanjuro is expert with breaths. He can tell the oxygen is not properly going through his son, obviously a breath of a lie. "Is it something you cannot say my son?" He suspected.

Tanjiro finally looks up and almost broke down. "I..I made a promise...s-sort of." Eyes all gliterry, Tanjuro pushed more. "Hmm...? Something fishy? Are you doing something illegal for my medicine? Tell me the truth." He did not want his son to be in trouble so he needed to know.

Good thing the breath of his son changed into honesty. "What? No! I swear! I dont do those!" It is quite fun foretelling Tanjiro's words and actions by the simple learn of tracing breath forms. Tanjuro allowed him to explain, "I-Its just hard to say...lets say I found a wounded rabbit attacked by a bear...and I aid it. But the rabbit didnt want its location to be found and I felt like I shouldnt betray..."

Tanjuro is actually not satisfied with Tanjiro's reasoning but atleast his son is not doing anything shady.

"I see." Then he pat Tanjiro's head. "You are a good boy huh." Tanjiro whose almost crying inside is weird out by that compliment. "Father...Am a good child indeed...?" He doubted his actions were forgiven however Tanjuro smiles and commented. "Yes, and remember a man keep his words. As long as what you are doing will protect this family and wont hurt anyone. That is something you can proud of."

Tanjiro finally let his tears slide off and hugs his dad."I love you father. I-I will do my best in your behalf!" Tanjuro hugs him back as he pat his back.

They forgive him.

"Thank you."

Kie whose watching behind the corner suddenly stepped in as she could not of course remain angry. "Oh Tanjiro!" And joining the embracing.

"Mom! Dad! I won't do it again! I really promise."

"Ok we believe you..." Suddenly, "By the way Tanjiro...?" Kie noticed, "Y-Yes mom?" She cup Tanjiro's cheek with the red mark of slap and travelled to his neck. "Where is your blue scarf?"

Tanjiro scratches his head with a distorted face of lying.

"Uhhh...It flew away by the strong wind?"

Is his lame excuse on this weather.

The next day...

"Muzan-san...?" Tanjiro went back to the cave early in morning but found no traces of that strange man. "Huh? He is not here anymore? Even though...we haven't got him a doctor...?" He isnt dead right? Looking around, no signs of other life inside. "...strange, he's able to walk fast by such wounded body?" Tanjiro did not say anything but Muzan had a lot of wounds but strange enough there is a lot of blood but the actual wound were scratches only.

Though Muzan smells lingers actually.
("Sniff-Sniff")

Tanjiro poke his own nose to distinguish the scent. "His blood...smells foul yet at the same time...It was that kind of smell I heard rumors about high status people... it smells like a lotus flower...? Also something else...something...else..." not realizing he was referring the scent of human and a demon.

Outside the cave.

"Oniichan!"
"Oh Nezuko."

Nezuko scolds him. "Gee, isnt last night incident got you? Why did you suddenly disappear?" Tanjiro made a nervous laugh. "I just check on something!" Nezuko looks with suspicion before she made an evil grin. "Uhh, are you what? Meeting a girl~?"

Tanjiro quickly went red. "WHAT!?" Nezuko burst laughing. "Tehehe!" Tanjiro pouts and points at her. "Nezuko! You are just 11 years old! Lets not talk about those stuff for mom and dad!" Nezuko brushes him off. "Well! Nao-chan from below the mountains had a crush a you so why get so stingy?" Tanjiro smokes out. "S-shut up!" Nezuko laughs. "Hahaha!" Until it died down. "Lets get back to work Oniichan!"

Tanjiro sighs in relief that the topic about romance stopped. "Ok!" And run together back to their house.

---

3 days passed...

Tanjiro actually tried to investigate, when he got the chance down the mountain into the village he secretly looked for him by asking people who bought his charcoal if they know a person named Kibutsuji Muzan but to his dismay nobody knows him.

Meaning he is indeed not a resident of this place. Weird out, 'What is he doing in the mountains anyway? Alone and...' unable to think of any other stories that could have led to that outcome. Tanjiro just breaths out the cold air. "I wonder if I will meet him again? I hope he is okay. Especially this weather..." still a bit concerned. "Also he is very pale...is he sick maybe?"

Tanjiro had day dreamed too much that he did not realize he got home already then-

"ONIICHAN WATCH OUT!"
"Eh?"

CRASH!

A large bean pot fall on his head. Everyone screamed as blood emerges. "Ahhh! Tanjiro!" Dizzy from the hit...Tanjiro's world turned blurry.

"No! Tanjiro Oniichan!"

'H-huh...? What am thinking again...?'

Oniichan!)))

Till everything went black.

A few moments later...

"Tanjiro! Thank God you woke up! I was scared that you would have died! That was a loud and strong impact after all...! Are you okay son...?!"

Eyes of wonder.

"...huh?"

Kie freaked out.

"Whats wrong? Your head hurts right? Tell me where exact, we will patch it up-"

Her son is like floating in thoughts.

"Mother..."

Anticipation.

"Where is my favorite blue scarf gift by father...?"

"Ehh...?"

WHOOSH~

...

---

Months passed...

'Father died so suddenly and I was left with a huge ugly scar in my left forehead due to the incident of a clay pot falling down apparently straight to my head. My skull is hard but not the skin they said. Or...the quack doctor said who lives below these mountains, where the other house where located that I have been lucky.'

Grabbing the hatchet and getting ready for work like he always do. Tanjiro traces his wound.

'I thought I forgot a lot of things because of this...scar.'

He forgot the Hii No Kami Kagura.
He forgot that he gave his red scarft to the injured Kibutsuji Muzan.

'I feel like I have forgotten a very crucial memory?'

Tanjiro vaguely remember his time spent during 12 years old.

'What could it be...?"

Now...

---

1 year later...

'I wonder how is that kid doing?'

Kibutsuji Muzan couldn't get off his head. The gentle boy who smiled purely for him. It has been a while he had encounter such a gentle...creature. Ehm, a human being.

Muzan got reminded of his humane side because of that kind hearted lil boy.

'I'm a man who knows how to show gratitude despite being selfish and self absorbed.' Just like Rui, that little boy who had a very sick body and couldn't play. His parents always worried so Muzan thought to heal the poor kid. However his parents did not like it.

Still that incident doesnt affect Muzan. Once he like someone he wouldn't mind doing a short vacation or a period of side tracking.

By observing them from afar, what a poor family he thought. Always selling charcoal, he heard that apparently the father of the household died making Tanjiro work extra harder than the last year.

Muzan thought they are healthy but just not rich enough in terms of human needs. 'Kamado Tanjiro, I would give his family a sum of money as a payback from him saving my life unconditionally.' So he approached them by winter time, you know...the sun is not up.

'But to my disappointment...'

When Muzan visited, he could not step further near because his eyes trembled when the boy...that same boy...'Noway...' he saw the earrings.

The cursed hanafuda earrings of Tsukiguni Yoriichi.

A family heirloom.

It was on that boy's ears!

'He was an enemy for me to exterminate.'

The sense of gratitude he felt suddenly quench into hate and fear. 'Before he realizes who am.' Muzan thought to kill them and get back to safety before they can pin point his existence.

Though seeing such a normal family with just kids laughing and playing, there was no threat.

Strange...

The strange sight and his strange change of heart. 'However somewhere inside me debating about it.'

Should he really kill them just because they had that Hanafuda momentum?

He hates the earrings, anything that reminds him of that shameful defeat.

But not that boy who lend his blue scarf and got soak with his red blood.

'After all he saved me and doesn't seem to be aware about Demon Slayers.'

Muzan knot his eyebrows.

'Not even the breath of fire.'

Which is why Muzan changed his mind.

Knock, knock.

In the middle of night, he knock at their doorstep with manners. Quickly the door opened and there he is...

"Yes?"

The Tanjiro who had his father's reminder, the earrings Muzan loathes the most. Muzan is very good at faking his facial expression to nice person image.

He smiled, "Good evening, Kamado Tanjiro." Tanjiro who is smart enough not to open completely, just slightly ajar...size enough to peek outside the cold night. "Uhh...G-good evening too, sir...?" What disturb him the most is, 'Why does he knows my name?' Also this man wearing a white fedora. It is obvious it's a city guy. "How can I help you?" Trying to be polite as possible.

Muzan's lips went flat shock. 'Hm? He does not remember...?' Then his eyes landed on Tanjiro's head injury. 'A scar in his skull? Did he got into an accident?' Well... 'Whatever, it doesnt change my goal.'

Muzan introduce himself and his purpose. "Tanjiro-kun, I'm here to repay my debt. I will be happy if you accept it." Tanjiro whose just much more confuse and slightly smiled unsure if he should shoo this person away. Opening the door a bit to be able to tell him to leave later. "H-huh? Sorry I do not recall doing anything to be thanked for lately...?" Kie's voice echoed behind.

"Tanjiro, who is it this late at night?" She stop on her tracks when a tall black haired and pale guy wearing extravagant clothes in this time of hour is strange. "Good evening madam. My name is Muzan, am here to grant your family something you needed." He handed a pouch. It was heavy and the obvious coin sounds. Tanjiro trembled in his palm. "M-money?!" Looking up, "But why Muzan-san?!" Tanjiro addressed him first name unconciously brain working to the memory he met him in the cave.

Muzan answered Kie's questioning face instead of looking back to Tanjiro. "Your son over here helped me."

Kie did not like it. "We appreciate the thought but don't you think this hour is kind of late for this...?" Also this is like a red flag, a stranger giving huge amount of money out of nowhere. Muzan ignored her warnings and reveals a folded familiar fabric. "By the way, here..." Tanjiro's eyes lit with recognition. "Eh? That's my scarf...!?" His missing blue scarf! Then it might be true, he must have met this man.

"I'm here to return this tonight." Muzan finishes and turned his back, only then Tanjiro finally says some audible confusion. "Um..." Muzan glances sides and smiles of acquaintances.

"I will be back tomorrow."

He walks away...

Tanjiro had the urge to chase so he did.

"Excuse me!"
"Hn?"

Behind him is Tanjiro with the money bag lifted back against him. "Sorry, but we can't take this money...R-regardless if it is a gratitude. After all this sum of money is too huge-" Muzan had a straight face. "It would hurt me more if you reject them."

Tanjiro can smell the man is offended so he just bowed and accepted the money as it is.

"S-sorry."

Muzan smiled sweetly then says another goodbye.

"Goodnight~"

...

---

Anyone's POV

'The next day he really came back. Despite this winter season he casually visited me back as if the cold never bothered him.'

Tanjiro is just uncomfortable.

That's all.

"Hello again Tanjiro-kun. Did you use the money I gave you for you and your family?"

The man from yesterday night is here again even though it is winter. It must be hard to travel, especially for a rich person. They must have those things called car's in tokyo.

"Err..."

Tanjiro's eyes gawks the moment Muzan took his hands and rubs them. "Look at your hands its all battered. What a shame..." blushing a bit, it tickles. "Uhh..." Muzan grins. "I can make them smooth again if you like? I'll take care of you-"

"I'm very sorry!"

Tanjiro knew he had to stop this man from invading their quiet life in mountains. 'I have gotten myself a strange person!'

Muzan raised an eyebrow, "For what?" Tanjiro push his hands away and bowed.

"I...I don't remember doing anything with you related to. The saving thing? Umm...so am confuse and I do not feel comfortable with this." He is obviously telling him go away. "I'm happy you wanted to pay back so much, I don't want to decline it but my mother said you were a suspicious person. Specially I cannot-" Muzan cannot conrol himself though he, "M-Muzan-san!?" Pulls the boy into am embrace and whispers. "I really like you now Tanjiro-kun, what a pure person." Tanjiro's ears went hot with anger and embarassment.

"L-let me go Muzan-san?!"

Muzan pulls away and captured his shoulders with a sweet proposal that he thought a poor person will just say yes just because it's money.

"Then how about this? I'll pay you well."

Tanjiro gave him a face.

Good timing, "Oniichan! What's wrong!? Why are you screaming-" Nezuko and his other siblings happen to be complete set and, "O-oh, it's you Muzan-san...why...you really came back for oniichan?"

Muzan remained his fake smile to others that he did not really care for but for the sake of his goal. "Kamado Nezuko isn't?" He would do anything, he will buy them. Though Nezuko is not a dumb mountain girl, she did not like how this person feeling close to them. Tanjiro begins to be hostile. "Why do you know my sister's name? Are you stalking me?" Wrong timing as well Kie emerge out of the house hold.

"Tanjiro, Nezuko can you get me-" immediately angry eyebrows. "You again?"

Muzan had a strong face, as if he was welcomed when obviously not. "Hello." Kie cut to the chase, "We do not want to be rude but you are bothering us. Please leave us alone." Its his a mother's job after all. Muzan chuckles, and tried to make a smooth lie. "Oh no, am just here to ask the permission for your son to come with me."

Kie darken her voice. "Are you hearing yourself?"Muzan just...just that he invites Tanjiro and ignoring the glare from Kamado Kie. Tanjiro thought he must stood up for himself and make things clear, the boundary!

"Come with you? You are creeping me out-"

"Work for me." Muzan said firmly, "In exchange I will guarantee your family's financial issues and safety." But somehow it sounded... 'Safety? Is that a threat?'

Kie marches forward, pulls Tanjiro's away and hide him behind her. A angry mother protecting her precious child. "Excuse me! My son is not going with a stranger like you. Leave Tanjiro alone." It is getting to annoying now for Muzan. "Why do you humans reject my kindness like this?" Angry nerves starts to get visible to Muzan's face.

"Muzan-san...I-"

Until Muzan snaps.

"Fine, if you want the hard way. I'll do it. But you know~ here am being gracious to take you properly. However you lead me now no choice but to take you by force."

So fast dark and long figured passed before Tanjiro's and-

WHACK!

"WAAAH! MONSTER!"

His sibling got captured by a nasty tentacle with razor teeth. Tanjiro realizes what is going on the moment his siblings were in danger. "T-TAKEO!"
Before he can run to Takeo, the tentacle moves and slams Takeo with Kie.

WHIP!

"KYA!"

Kie and Nezuko was slapped by one of the monster tentacles.

"MOM! NEZUKO!"

Kie got captured by the other tentacle then got slammed this time to Hanako and Shigeru who both fell to the snow. "KYAUGHH!" Nezuko crawled at the floor to go towards Shigeru and Rokuta. "E-everyone!" While Kie yelled her son's name to make him snap out of it. "T-TANJIRO!"

He gasp and quickly glared at Muzan with teary eyes. "M-Muzan-san...what on earth are you?" His heart is so nervous as those red eyes glow.

The snow fall silently and yet nobody can rescue them nor witness this event.

"Me?" Muzan chuckles darkly before he sighs and says, "I guess your family does not have any knowledge of his legacy." As for Kie in the ground with broken arm from the impact of Takeo hitting her earlier with the tentacle, she recalled a myth her husband used to share. Tanjuro when he was still a teenager and still healthy, removes the paper covering his face with a smile to his girlfriend Kie.

(('This Hii No Kami Kagura is to cast away demons, it was never really for the sun god or anything. It was to keep away Kibutsuji demon that our ancestors said loathe our existence.))

Kie said below her shivering voice. "Wait...are you...a de-" Muzan with sharp ears heard it and clarified everything. One truth, "Yes, am a demon. Not just any demon,am Kibutsuji Muzan, the king of demons."

Kie is now more scared but her fighting spirit came back. Knowing now it is an enemy indeed before them. "It's what Tanjuro mention before when we were teenager...! Demons, Kibutsuji the enemy of Fire-"

"Ow...!"

A scream.

"HANAKO!"

Muzan had turned them to his plaything. You know,dragging their legs beneath the snow, smacking them,choking them. Making them screaming all kinds of terror. Only Tanjiro is not hurt but he couldn't breath by watching his family like this.

"Don't you feel cocky monster!" Takeo who raised his machete to protect his younger siblings.

"Now all of you kneel before me." Muzan chokes Takeo. "KUHHACK!" Nezuko moves near to kick Muzan. "LET HIM GO!" But then Nezuko is pulled to the ground and got slammed "Aaaah!"

Tanjiro breaths out. "S-stop!" It gets bloody, because he now sees blood oozing from their heads due to the impact of being thrown around here and there.

"PLEASE STOP!"

Pathetic, Tanjiro couldn't move himself from gawking instead of fighting. He was a coward, 'I need to protect them because am the e-eldest...!' Then Rokuta cries. "Waaah! Daddy! Save us!" Irritaring Muzan. "You shut up." Commanding a sharp tentacle to silence the kid. Finally Tanjiro bit his lips and made a move. 'MOVE YOUR BODY AND FIGHT HIM!'

"NOOO!"

SLASH!

Tanjiro run towards Rokuta to cover the youngest in process his ponytail got cut off.

"...!"

Surprised and shortly resumed being a villain that he is. "Oh, I cut your hair. I did not mean too. It is your fault shielding that thing." Tanjiro twitches in anger. His face had vein pops. 'Thing? A thing?' It is his damn family! "Why are you doing this?! You said I saved you so why are you hurting my family and threatening me to come with you!? What do you want to play here Muzan-san!?"

"I like you."

Tanjiro must have misheard it.

"What?"

Oh he does not, Muzan made sure it is loud and clear.

"You captured my interest so much that I cannot stop thinking about you." Even he raised his hands to welcome him to his arms. "Come with me Tanjiro, spend an eternity with me if you do not want me to kill your family in behalf of my grudge against the owner of that hanafuda earrings of yours."

Tanjiro just breathing in and out of his nose with his racing heart from the adrenaline rush of almost got sliced in half. "M-my father's earrings...?"

Kie rose up with her broken arm and tied up hair falls down, revealing such a very long hair like Nezuko's whose keeping Hanako and Shigeru in check. "Be silent demon! My son will not become a demon! Over my dead body!"

Muzan vein pops from the dare. "Dead body?" She is in the way to his romance. "As you wish-" Nezuko catch up and, "No! Mother!" Before they can blink twice.

STAB!

"NEZUKO!"

Nezuko is stabbed in the neck. "AAAAH!" They all shrieked. "What a foolish girl getting in the way. Now she got stab instead." Muzan injects his blood to Nezuko. He never intend to kill them anyway. In fact he wanted to turn them all to demon so he can keep Tanjiro...but it doesn't seem to work that way. This is a mess.

Thud.

Falling down with gurling sound in Nezuko's throat choking with blood. "Aughrrr...!" Tanjiro quickly goes to her side. "NEZUKO! HANG IN THERE! ONIICHAN IS WITH YOU! DONT DIE!" Shaking her sister. It was worst.

WHACK!

"Hn?"

A rock thrown to Muzan, "What did you do to nee chan monster?!" Hanako is the culprit. Muzan is not hurt but he was not happy. Trying to still be in poise of the situation, he smiles with malice. "Relax, your beloved big sister will soon become a demon too. She will live long...no, she will live forever."

Kie's eyes widen. "Don't tell me...!"

Tanjiro looks at him and smells in the air as Muzan reveals his plans. It did not smell like a lie. Muzan did explain himself, "...The attack I made is never intend to kill your mother Tanjiro. I wanted to turn her into a demon as an example, with that you will understand the beauty of eternity. If you do not choose to come with me, I will turn them all into a demon instead of you."

Alarmed. "No! No! Nezuko you cannot become a demon!" Nezuko still choking with her hair down in process. "It's either she dies from my blood or she becomes one of us. Hehe, entertaining~" Nezuko stops choking on her own blood and eyes went white.

Tanjiro is very angry. "Muzan..." his beautiful sister in a mess. "HOW DARE YOU!" And throws the hachet and makes a run towards him.

"Weakling."

Muzan dodges the flying hatcet and grabbed Tanjiro's neck. "KHH!" He got choked. Lifting him with threatening demonic eyes.

The machete chopped Muzan's other shoulder, Tanjiro thought he won and only to witness the quick healing abilities of the monster. "Ahh~ yoy just ruined one of my favorite clothes."

Tanjiro starting to loose his oxygen. "Kuagh...!" Muzan is not smiling anymore,his eyes narrowed. "Now watch your sister become a demon Tanjiro. Blame yourself for being a bad boy, if you were obedient this won't happen~" he was forced to look at his sister's transformation. Muzan puts him below his feet and saw Nezuko awakening, she stood in a zombie way and he had a bad feeling. "N-Nezuko!" Nezuko launch an attack against Muzan though. "Graaaahhh!" Muzan chops her off. "Nezuko!?" And collapses.

Bored, "Hmm? She fainted? Oh who cares..." then pulled Tanjiro's remaining short hair strands. "Ghhh...!" Gritting his teeth with frustration. "So what is your decision?" Muzan is just waiting for him to admit defeat. "This is not fair...! I cannot-" Tanjiro suddenly had the urge to cough.

*COUGHS! COUGHS!*

Muzan throws him away. "Ack!" Hitting a tree, Muzan walks to Kie and hostage her. "This is the last straw Tanjiro. Me or your family?" One of the tentacles with mouth opens and bites Kie's shoulder. "Uuuaaghh!"

"Stop..."

Then Hanako was next bitten.

"Aah! Brother!"

"One,"

Shigeru got bitten next.

"Stop...stop..."

Rokuta is held up high and bitten.

"Two,"

Takeo is bitten while unconscious.

"No, no,no!"

Seeing Nezuko almost dead body on the bloody ground.

"Three."

Tanjiro submitted defeat.

"NOOOO! PLEASE STOP!"

He dogeza at the cold snow, properly as he whimpers and beg for their lives.

"FINE! I-I'L GO WITH YOU! TAKE ME, EAT ME, ENSLAVE ME WHATEVER YOU LIKE! JUST PLEASE STOP HURTING MY FAMILY! PLEASE DO NOT KILL THEM! MUZAN...!"

It was so unsightly, his nose running and his voice shaking with his hands freezing at the snow where he bowed to Muzan.

Super pathetic.

"Do not take more than it is..!"

Sobbing.

Muzan whose face is blank and cold made an evil smirk.

"That's what I like to hear."

Immediately dropping them all. Kie tries to reach out weakly at her bloodied body in the floor.

"Tanjiro...no...!"

His siblings beg and cries. "No! Oniichan..! Don't leave us behind!"

Muzan looks down at him. "Stand up Tanjiro, let's go to my fortress." Tanjiro murmurs. "Promise me." Hearing the boy still had words to say. "Hm?" Tanjiro is crying and beg more. "Please promise me...! That in exchange of my captivity you will let my family live! And return Nezuko to normal!"

Muzan sighs. "Isn't that the same bargain I offered you earlier and you rejected it? Also how awful you make it sound like a prison. How do you correct yourself, hm?" Muzan warned with eyes. Sensing the demon's anger, Tanjiro quickly grab his clothes and continued to plead. "N-noway! I beg! Please! I was at fault...! Forgive me!"

"I'm kiddin. I'm not that cruel, I will keep your family safe from any demon attacks." Muzan said and there is no smell of lie, a bit of joy taken, "Then...!" It sinks to despair right away. "But there is noway for me to revert back your sister into a human being."

Tanjiro feels like he is going crazy already. "Y-you are lying right!?" Muzan is straight forward to this truth. "Remember this is your fault, your lil sister Nezuko became a demon because of you bitch didn't follow my commands." Making Tanjiro blame himself. "No...no..that is not true! I...I...!"

Gently his point finger goes to Tanjiro's lips.

"Hush."

Looking up with hopeless feelings. "Let's go shall we~?" Seeing that smile across the devil's face, Tanjiro had stop struggling for the meantime. "...Ok." and accepted his fate.

Kie's voice roared behind and Tanjiro never looked back.

"No! Give my son back! Tanjiro...Tanjiro!"

...

---

In the Infinity fortress, Muzan's room.

"Come here Tanjiro." The place has dim light, yet Tanjiro can see his own feet and hands still has Nezuko's blood traces on it, they trembled horribly. 'I'm shaking, I'm shaking, I'm shaking!' Muzan called out. "Tanjiro." But Tanjiro is too detached from his fear to his fate. 'I can't, I can't! This is impossible!' Because he isn't that dumb, by this smell he can tell what is the older man plans were with them alone to this room. "Kamado Tanjiro?" Muzan continues to call out.

Tanjiro shaking his head and proceeds to scratch them to calm himself, his thoughts were in a mess. 'Why? Why did it end up like this? My body...my legs...my hands they won't stop trembling. I'm in danger? Is that it? What will this demon do to me? Will he make me his slave...or will he-'

Cold hands touched his shoulders in place.

"Tanjiro-kun."

"(GASP!)"

Muzan is already near him, acting like a gentlemen his natural beautiful face. "You don't have to be so nervous. Its just you and me in my room. If you are afraid of demons that surrounds you by your keen of smell, rest assured I will protect you. They are under my control. It will be alright." Tanjiro awed,his stomach twisting inside this...unbelivable man!

'This man...Earlier he just attempted to slaughter my family and now he is able to say such nice words...It makes things more scary.'

That suave assurance.

"Okay?"

Noway.

'Because he...because he intend to-'

Muzan escorted him. "Now let us go to bed. I will make sure that you will become mine~" Tanjiro in instict slap his hands away and yelled so loud with deep rejection. "DONT TOUCH ME!"

Muzan's kind demeanor drops. "Huh?" Tanjiro covered himself by a hug. Yes he was embracing himself to keep it together. "I-I can't do it after all. I...I fear you! But...but more than t-that. T-this thing...this activity that will happen between us...I dislike it!" Teary eyes. "Please,please just let me go."

Muzan clicked his tongue. "Are you defying me? Do you have any idea what effort it took me just to get you?" Muzan grab his jaw and squeeze them. "Hmff!?" Zooming his threatening glares to the boy.

"I could have just slaughter them and take you by force but I didn't? Did not I gave you a choice? And you think am forcing you? Your head is hard as a rock and I know since you headbutt me before. However I won't let this insult slide!" Muzan suddenly throws him to bed.

Tanjiro did not expect that impact of pain. "Ack!" Gasping again from sudden rough moments. Tanjiro's back landed to the soft bed, but the strong impact of suddenly spinning in the air and landing in rush made his back gain pain of his fatigue from the situation. "I'm sorry!" Is all he can say while lifting his hands to hide himself.
Muzan narrowed his eyes upon the frighten sight of the boy. 'He doesn't stop shaking.' It is annoying but can you blame him?

Muzan sighs.

"I'm a very impatient person. Do not make me hurt you than this." Tanjiro just responded a whimper. Muzan called out once more with a commanding voice this time. "Look at me in the eye Tanjiro!" Tanjiro jerks up and run for the door. "NGGHH!" Muzan grabbed his collar and by accident-

SLAM!

Knock him out in the process.

"Oops."

Tanjiro just lost conciousness at the floor where he got slammed hard.

"Oh well."

Muzan does not care either way, he will make him his and his alone.
...

Re opening his eyes like a dejavu...this time he saw the ceiling. "Argh...? Where?" Feeling sore and unsure why. 'My body hurts a lot...why? Is that?' Tanjiro sits up while clutching his head. "What happen to me?" Only to see pale arm fell off in his chest to his torso. His movement made that flesh roll over. As if...the other is in rest mode. 'An arm?' Whose arm is embracing him as he is bare naked in his chest? "Wah!" Oh yes it his the demon king. "M-Muzan-san...?" Realizing how abnormal the situation is. 'Wait, he is naked and am n-naked...? C-could it be...' the reason why his body hurts and felt cranky.

(Gulps.)

Tanjiro's finger made it's way to touch his bottom by his fingertips that went inside the sheets covering their lower parts. 'I-It's wet with something s-sticky and...' Confirming. 'B-Blood...!'

"Hmmrr.."

Tanjiro proceeds to plan an opportunity of escape. 'I have to get out of here!' About to sprint out of bed, "Ah!" A strong hand locked his left wrist and pulled him roughly back to lay on bed. "Where do you think you are going?" Before Tanjiro know the man is above him. Muzan with bare chest and a handsome face with his black curly locks.

Tanjiro did not want to feel embarass being naked with another man. After all in japan being naked with eachother makes you closer. "Y-you! What did you do to me!?" But the fact knowing Muzan declared to be romantically attracted to him makes him alert and expect suspicion by being naked together in bed,body hurts...the red and white liquid on his bossom. No doubt he was raped by this guy.

Muzan chuckles and had an evil smile at he look down at the cornered meal below his sight. Tanjiro's face is visibly embarass, shy and scared yet there is hatred and disgust. Softly his pale cold hands decided to go ahead and touched the boy's ear by his left hand and travelled to Tanjiro's jawline "You don't remember again? You are too young to have Alzheimer's you know~" he zoomed his face, his hot breath to Tanjiro's left ear.

"But if you want to know what happen last night, sure I will tell you~" moving away just to see again Tanjiro's flustered face, there is it. The boy was in horror. Muzan evil grinning widens. "You were splendid last night. A very obedient dog~" Tanjiro burst in unbelivable tone of his. He just could not accept it did happen. "So you did do it!?" Muzan starts to crawl down and giggles out to Tanjiro. "Hehe~Now it is time for round two now you are awake unlike last night ."

Tanjiro knows they are both naked below, it was an awful sight that this large man crawled all the way to see his... "W-what? No way I would-" Tanjiro hide his thing as Muzan is watching his being.

"Let's spread your legs~"
"Don't-"

Ignoring the prostest. "How beautiful." Muzan strong hands easily takes off Tanjiro's hands shielding his small and cute...Ehm.

Tanjiro panics, "N-no! You are a male and am a male so why are you-" Muzan laughs. "Ahaha." Then points out facts how he must have lived. "Gender does not define an old being like me. Not anymore~" then he turned serious. "Now behave yourself...leave it to me~ Tanjiro." Tanjiro felt his body went stiff by the commanding eyes, "-Ah!" He did not even had chance to cover his mouth by letting out an obvious moan. All he can do is have some pleading eyes as he look at his penis being captured by those firm big hands. Muzan's palm moving up and down.

"Nhh-" his body is having electricity, tossing a bit but trying to remain in place of the bed, just not to be obvious that it actually feels tempting to let it be. "Y-you can't! Am underage!"

Muzan rolled his eyes. "It's fine, you never heard of Wakashu?" Then smirks. Tanjiro had a questionable face. "W-wakashu?" Muzan shared to the country bumpkin. "It's a legal terms of a young boy having intercourse with older man here in japan." Tanjiro had the face of pure disgust and felt stupid.

"I-I never heard of that! Thats probabbly invented story of yours! Please spare me this! Get off me...!" Tanjiro yelling, such rejection same like it did before, getting boring. "Shhh~" Muzan is nearing to get pissed. "This isn't right Muzan-san!" Tanjiro's crsytal eyes, Muzan knows the boy will cry soon. Muzan stops moving his hands from below, he reminded him of their somewhat contract.

"Look here. You came here to be mine, if you do not keep yourself as mine...not only Kamado Nezuko will be a demon." Tanjiro went again fearful. "You can't turn my family into demons! Never! Don't do that!" Muzan stared straight at him. "Then what is your action?" Tanjiro is lost for words. 'T-that is right. This guy is my master now...I said I will do anything just to keep them...' Tanjiro did not bow down his whole body at the snow for nothing so...he had no choice for real.

"Spread your legs and behave like a good dog okay?"

"...F-fine, just...just please be gentle."

Muzan made a evil triumphant smile. "That is what I liked to hear." Then moved his face next to Tanjiro's little thing and rub his cold cheeks to it's throbbing and hot rob. "Hmm~"Muzan hummed, "I can feel the life of your hot penis." He purposely said that to make Tanjiro turned on with much more embarassment. "H-hahh?!" It is effective, Tanjiro's thing move and twitch straight up by the compliment.

"Hoho~you like that you slut?" Muzan is sexy when he said it. Tanjiro gulps. "N-no." Tanjiro scold his easily turned up body. Muzan kisses the tip.

("Mooch")
"A-Ahhnn-"

Then hungrily said, "This will be a delicious meal~" Tanjiro looks down and witness Muzan just licked his tip and swallowed it. "Ghh...!?" Tanjiro confuse why it has to be eaten, it occured. 'Is he going to eat me because he is a man eating demon?!' But he was wrong. Muzan is simply giving him a blow job. "Hahhh...hahh-" Tanjiro is starting to feel fire in him.

The slurping sounds, the moving tongue and a closed spaced mouth. A very hot tunnel, Tanjiro is sweating. 'This is very bad...am feeling it. Am feeling this intensity feels good-' Tanjiro came by accident and surprises Muzan. "Hm?" Tanjiro snaps his head. "S-sorry!" Tanjiro thought he peed.

However..."Hohh~" Muzan stops eating his little mushroom. There reveals a white liquid just slip out of Muzan's mouth, Muzan wipes it by his fingers and examine the white cream. "You came so quickly?"

Muzan is amused. "I was not wrong when we first did it then~" Tanjiro gulps at Muzan, watching the man entertained on his own thoughts. "You were asleep when I did it, Which is why the blood on your bottom...the pain of it. You did not felt it."

Tanjiro raises his eyebrows why Muzan would let him know the details. "Ahhh~ Tanjiro, you are great." Muzan touches again his cheeks and showed him how he licks his lips with the milk Tanjiro gave him. "I will make you cum so hard till you beg for more~"

Tanjiro immediately know he is in hell hole but could not say another protest since Muzan cut off the conversation and went back devouring him there. "Haahhhhaaa-" Tanjiro arched his back and his head weighten in the pillow.

"This is weird!" He says that but Tanjiro deep inside, 'Why? Why does it actually feels good?' Tanjiro starts to drool as Muzan lick his thing throughly like a popcicle stick. The man eats human body parts, so no wonder he is very good at licking and chomping. Tanjiro never masturbated before,he never used his ugly hands to pleasure himself.

'This man's...palm is so smooth..' Tanjiro did not know he was mesmerizing Muzan now. 'He also smells nice...then...his lips when it kisses me...'

"Ah!"

Moaning when Muzan peck at his thing, Tanjiro shut his eyes in process. 'They feel good...so good...I...I want more...I want-' Tanjiro gasp his eyes out. 'W-what am liking this for?!' Then he felt pain in his hard thing. "Very hard~ that is good Tanjiro, just let it out~let it out~" Muzan teased it.

Muzan pulled it in a way to force Tanjiro to let it out, like when someone feels peeing and they want to stop it. Muzan is making it worse to stop for Tanjiro. "Come on, let your seed out Kamado Tanjiro~" hearing those hungry words Tanjiro could not retain compose anymore. 'I-It's coming out-' biting his lips.

"Let it go Tanjiro~ feed me more of your tasty cream-" Tanjiro felt painful on his second come. "Its out-oowww...!" Because this time,it was more white fountain than the first. Muzan joyfully open his mouth to be sprayed by it. "Hehehe~very good, very good."

Tanjiro pants, 'H-he treats me like a good dog or something...! Wait am his...dog now, the moment I beg my family to be spared-' But he was starting to get dizzy. "Let's make more~" Tanjiro just gasp the third time Muzan blowing him up.

"M-Muzan-san...Muzan-san..." he sub consciously utter the man's name as he is panting and moaning. 'More...more...' his head chanting, 'Do me more...' Tanjiro's hands that had been behaving near his mouth went down to his own chest. 'I feel so...so hot...why do I feel so...so...' Tanjiro came more and more. If to count it was like 5 times already and Muzan starting to get concerned. "You keep coming huh..." then finally notice the boy touching his chest near the nipples. Tanjiro is touching them!

"Hehh~" so Muzan crawled up. "You want to be played there hm~?" Tanjiro looks at him all fuzzy headed. "Hh...huh?" Is his response. Muzan evil smiles then gently remove Tanjiro's finger that is capturing his own nipples. "I can please you better~" proceed to suck the right and pinch the left.

"Wah!?" Tanjiro woke up in sense that Muzan is done from below and is now in his chest...sucking and pleasing them.

Tanjiro drooled and accidently says outside his mind. "HAahh...I-It feels good Muzan-san!" Muzan stops and almost judge what he heard. "Pardon?" Muzan finally had a better look on Tanjiro's face. They were so red, the boy's pupils were like in high fever, then...his lips or more like his mouth is open, like inviitng a kiss and there is that drool trail in his jawline. "Tanjiro-kun...you..." Muzan felt light hearted to know that this innocent boy is starting to abide with him. "I love you." Muzan says and then kissed him.

"Hhmm?!" Shock, Tanjiro shut his eyes again. 'W-what?!' Muzan nibbles his lips, as if he was trying to eat an ice cream.

"Hmm~Tanjiro~" the way Muzan mention his name, Tanjiro's ear feels ticklish. "Mmm-" Tanjiro open his eyes and closes them again, "Mmm..Muzan..san.." and submitted to the kiss. Tanjiro kisses back. 'I don't know why...it felt tasty too...' Muzan eating his lips, Tanjiro did not mean to open his mouth he was amature on kissing, "mmhhh~" Muzan decided to go next level and inserts his tongue. Tanjiro jolts. "Mmmh!?" Muzan comforts him by grabbing his hair.

"It's okay~" he said shortly and kisses a French kiss. Tanjiro did not know what to do so he let him, all he did is kiss back but not good with tongue fight. 'This...man's kissing me...' Tanjiro not gonna lie. He smell it, 'His kisses felt like he was madly in love on someone like me...' Tanjiro's body relaxes in the rythm of deep kiss. '...What did I even do to make him so charmed on me...?'

Muzan tells him. "I will make you pregant Tanjiro-kun~" Tanjiro whose light headed already. 'D-does male get pregnant?'

And so...

"Wait don't enter-"

It felt painful at first.

'Is this what female feels when they get penetrated?!'

Yeah!

Things escalated from sweet to much more wild. "Ah,ah,ah...Ahh!" Muzan thrusting in Tanjiro's. "You are so tight. I expected something from you but you surpassed it Tanjiro-kun~" for some reason Tanjiro from behave starts to dislike things again and spats. "L-liar! *sob* Didn't I ask you to be gentle? Why are you so rough-nnhhh! Not so fast! You are heavy-" the sweet sex from earlier must have been an illusion!

"Hahhh,hahh," every thrust a moan and panting goes out. 'His big thing is violating me inside. Is this what a girl feels like? So scary...so scary...!' Tanjiro clutch at the bed sheets. "Too strong...! I might break in half please!" Tanjiro is drowning in pleasure, his eyes reflects differently from what he says. Tanjiro just knows he is getting corrupted. To be okay with this...no, it is for his family that's why it is ok. 'Dad,Mom, Shigeru, Takeo, Rokuta,Hanako and Nezuko...it hurts a lot...! Lend me your strenght!'

"Tanjiro am coming~ Be a good boy and take it all in okay~?" Panting, "T-the what now?" It spills out. "Buaaaahh!" So hot...and strong like water's rampage. "W-what was that?!" Is Tanjiro's question 'Hahh, hahh, Its so hot inside my stomach! What did he do?! Whats with this sticky liquid going inside me...!?' Muzan chuckles. "It felt good~right?" Then received another kiss in lips.

"Mmmh-" stopping a bit, "I like you a lot Tanjiro. Entertain me more and more~" eventually Tanjiro got flipped over. His buttocks shown, the pipe just went in. 'Ah! N-not another round?!' Shutting his eyes and grit his teeth, clawing the bedsheets. Eventually pleads again..."Nooo! Make it stop! You are destroying my body Muzan-san! Kuah-Ahh!"

Oh it's finally over.

Tanjiro's heart thumping so loud as he feels exhausted. The sweat and smoke releasing out of his body as he laid like a tired flower n the bedsheet. Watching Muzan just sitting at the bed and watching him with fulfillment.

The forced pleasute from earlier subside amd now hos body starts to tremble again upon the horror of truth what on earth happen to him with this devil.

As he trembles in his small voice...Tanjiro frowns, and dared to ask. "W-w-why...?" Tanjiro glared between their eye contact with tears. "Why d-do you love me f-for?" Trying to put a brave front despite his obvious shaking physically, mentally and vocally. Tanjiro had small blush as he is atleast acknowledging Muzan's feelings for him. "Do I deserve y-you...?"

Muzan is surprised at how Tanjiro still try to be polite in interrogating him. "You..." Muzan smiles then caresses his face, to swipe Tanjiro's sweat. "You really forgot?" Then his eyes landed to that strange scar in Tanjiro's forehead. "Is it this scar's fault? You got into an accident?" The way Muzan sounded worried, Tanjiro doubt it but..but then again...'I smell it, his hands are cold but gentle on me. Yet these hands probabbly slaughtered and tortured people.' Tanjiro admits. "I did. Then I gain this scar...after that everything just..just the way it is." Muzan nods, "I see." Then placed a soft kiss to his said forehead.

Chu~

Tanjiro froze. "Mu-"

"Goodnight Darling~"

Tanjiro just confused if he should embrace this completely or still... "Muzan-san..."

Muzan dismiss the topic and stood up to get his black bathrobe. "When you feel better, take a bath. It's on the right side of our room." Muzan terming 'our room' Tanjiro's ears went red. He freaking know what that means. 'Why does he say it like were married couple in one bedroon!?'
Well it is because they are.

Officially and forced. 'He is a pedophile isn't he!'

---

A bit later...

Muzan decided to introduce Tanjiro to his Twelve Moons.

"Today is a feast." He declared. Tanjiro is pale, infront of him is...'Demons...!' And they are so many. The table is long alike to a meeting table. Surprisingly it is still japanese table. It was not western. Tanjiro feeling his feet numb from sitting on it, not because he isn't used to it. 'The pain in my waist still lingers after that rough sex...' blushing alone in his thoughts, he heard Muzan. "Meet my wife Kamado Tanjiro.

From now on treat him with respect as how you treat me. Anyone who dares to eat him or his family will pay either the price of their life or a very painful punishment..." witnessing how Muzan narrowed his eyes that intimidates everyone.

'The smell of fear on his authority.' But more importantly. "W-who are you calling wife?!" Tanjiro just going crazy. "Were both guys! There is no wife and husband in this relationship!"

The Twelve Moons went dumbfounded. 'H-he answered Muzan-sama back!' They thought it is rude and also they already assumed the boy will make Muzan slap him or what...no...Muzan actually, "Pff-" and burst out laughing. "Ahahaha~" embarassed. "W-what's so funny!?" Muzan suddenly shape shifts into his female form.

"Okay~" Tanjiro jawdrops. "W-what you are a-" Muzan explained briefly. "If you want I will be the wife then, Ne? Tanjiro-kun~" Tanjiro shakes his head. "No,no! That is not the problem!" Tanjiro is mad. 'I can smell he is messing with me!' Muzan transform back to his male form and commanded. "That is all. You may now all eat."

When they open the top of their plates. Tanjiro is horrified and trembled. It is disgusting sight...cannibalism. It was not so obvious at first glance because the said foodies were looking alike to a normal fish in a first look but...

"Hahh,hahh..." Tanjiro starts to breath in an irregular way, his heart is beating so fast due to the gory conclusion what it was at their table. His nose can tell the smell is not an animal meat. Hands,Cut fingers,Eye balls in soup of blood,Ears,Human legs that looks like a chicken,Arms,Neck and other things that is just plainly stomach aching. 'These are h-human bodies...! Human meat...!' Tanjiro covers his mouth in an attempt to stop himself from vomitting.

Muzan ignored him and proceed to fill the empty cups for wine by his blood. "Since am in a good mood~I will allow you my Twelve Demons to drink another set of my blood~" the smiling fangs. "Muzan-sama thank you! Were honored!"

Tanjiro saw how thristy they are on Muzan's blood. They were much more excited drinking the bloody wine of Muzan than the pieces of human meat in the table. This made his attention change from feelimg sick into curiosity.

'I wonder if his blood taste good?' Tanjiro smacks himself mentally for even thinking that. 'Idiot! Drinking it means you will become a demon! Like...like Nezuko-' Muzan felt like he can read the boy's mind.

"Do you want my blood?" Tanjiro jerks up his head to meet gaze of observing eyes from Muzan. Muzan rephrased the invitation, this moment Tanjiro had a normal human meal and empty cup.

Muzan points his finger to that cup. "Do you want to live forever with me Tanjiro?" It sounded like a wedding proposal that Tanjiro did not know how to react. "T-that's..." seeing the troubled face of Tanjiro, Muzan brushes it off by a pat. "Don't worry, I will not force you. As long as you are mine..." Muzan looks in distance of the room. "You do not have to become a demon. Especially I want to hear your stories out of the sun."

"Muzan...?"

For whatever reason Tanjiro felt his melancholy. 'I smell sadness from Muzan when he said that.'

...

---

1 week later, Tanjiro is surprise at Muzan. 'After that first sex with him he stopped flirting at me. Instead he...' Tanjiro has been locked up inside their room. Tanjiro had wear Muzan's clothings which is too big for him, because the man never thought of buying some stuffs for him despite saying they are married or whatever delusional things Muzan would assume against Tanjiro. 'I noticed Muzan had a lot of books he tend to read and fully focus on it. He doesn't even remember I exist in this prison...his room.' Tanjiro is frankly getting bored and worried about his family. 'They are alive right...?' Seeing Muzan sitting at their bed and busy reading a book with full of english words that Tanjiro does not understand at all.

He dared.

"U-um, what are you reading?" Muzan's is slightly startled by the proof he stopped flipping the page and slowly turned to see Tanjiro at his left side standing with a frown. As if the boy is trying his best to feel comfortable in an attempt to converse. "About rare flowers."

Muzan said shortly. Tanjiro fidgets,"U-Uhh huh, I-I see you like flowers...?" He trailed off unsure how to continue. Tanjiro actually had a plan, 'Ackward! But I must build rapport to eventually ask how is my family doing outside...! Do your best Tanjiro! Continue the conversation!' Muzan is silent and staring at him though. Sweatdrops, 'Did he find out already!?'

Out of nowhere Muzan moved his right hands to go inside his vest pockets and revealed a small paper. "Here for you." Tanjiro blinks. "Eh?" Well, Tanjiro did not want to offend him knowing what the man is capable of so he accepted it. "O-okay?" Opening the folded paper, Tanjiro's heart skip a beat and his nose exhaled his tension out into...blushing cheeks and yearning eyes. "T-this hand writing..." he knew it, it is..."Hanako's hand writing!"

His family is alived then!

Muzan smiles at Tanjiro as he promised.

"From now on I will cherish you Tanjiro, I'll get you back your family as long as you stay with me forever."

By forever means becoming a demon right?

Before Tanjiro can say anything else he got kissed in the lips.
