MUZAN KIBUTSUJI

01. Muzan and his needy human

02. Fucking you into the couch, watching you writhe

03. You swore your husband was sick. That his body was too weak to even fight off small burns like the sun’s rays; that’s why he locks himself in his study. So why is he ramming into you and restraining you with so much strength?

04. Muzan and his god complex

"You should be thanking me—thanking me for allowing you to feel me at all. Say it." ✦ "thank...aphf thank you!"

05. He bent you over his lap, asking you to tell him of your day. Every time you lie, his palm slams down on your cheeks.

"nghh... what was that for?" ✦ "That was a lie. you did not go straight home after." "I'm unsure whether to punish you for disobeying my orders or lying about it."

KOKUSHIBO

03. Inspecting to see if his human girl was good during the day

04. A pure representation of the control he wants in bed. Control over you, your movements, orgasm, moans—everything

05. How he thrust right after punishment sex. After all your crying, he goes slow right before releasing inside and wipes your tears

06. Such a peaceful cuddle and kiss turned dirty. When his fingers slip between your thighs

“Stay. Still.”

DOUMA

"Awhh, you're being lazy. didn't want it to come to this but it seems—" ✦ "no!...phf, I'll m-move."

AKAZA

01. Even a modernau!Akaza would find himself sneaking through your window at night as your secret boyfriend

02. He only visits at night, every second he's inside you feels as if he tries to make up for days he's been gone.

03. In another universe, Akaza is obsessed with morning sex.

“you’re sick and as much as they don’t want to admit it, the upper moons hate seeing you like that.”

⋆˚࿔ MUZAN KIBUTSUJI

You’re curled up beneath heavy blankets, fever painting your skin hot and clammy. A cough rattles your chest as you murmur weakly,

“…I don’t feel so good…”

The air shifts, heavy with Muzan’s presence before you even see him. He appears in the doorway, gaze sharp as ever, but something unsettled lurks beneath the red of his eyes.

He strides to your bedside, movements smooth, deliberate. His cool hand presses against your forehead, and his frown deepens instantly.

“Pathetic. A fever has you bedridden? How fragile can one body be?”

You huff softly, trying to burrow deeper into the blanket.

“Not very comforting…”

He exhales through his nose, clearly biting back a sharper retort. With surprising gentleness, he adjusts the blanket up to your chin, tucking it close like he’s trapping you from the cold air.

“If you waste away like this, you’ll be no use to me,” he says flatly. But his voice is low, almost strained.

His eyes linger on your flushed cheeks, your trembling lashes, the way your lips part with each shallow breath. He looks away quickly, jaw tight, as if your vulnerability is something he shouldn’t have to see—something that claws at him in ways he doesn’t want to name.

You mumble drowsily, half-asleep. “You… hate this, don’t you? Seeing me like this.”

His hand freezes where it hovers above you. He could lie. He should lie. Instead, his voice drops, quieter than a whisper.

“I despise it.”

For once, it doesn’t sound cruel. It sounds like confession—like watching you sick cuts deeper than any enemy ever could.

When you wake later, the fever dull but still lingering, you find water at your side, a neatly folded cloth, and sliced fruit arranged with meticulous care. Muzan is gone, but the ghost of his touch on your forehead and the silence of his unspoken worry lingers.

⋆˚࿔ KOKUSHIBO

The fever has you pinned down, your body weak and heavy beneath the blankets. Each cough feels sharp in your chest, and when you open your eyes, Kokushibo is already there, kneeling silently at your side.

His six eyes scan over you, unreadable yet unrelenting.

“You should not have allowed yourself to reach this state,” he says, voice even but edged with something heavier.

You let out a soft groan, tugging the blanket up higher.

“Thanks for the lecture… I feel so much better now.”

For a moment, silence. Then, Kokushibo reaches out, long fingers brushing your damp hair back from your forehead. The touch is careful, deliberate—like he’s unfamiliar with the act, but determined to do it right.

His gaze lingers on your flushed cheeks, your trembling breath.

“It displeases me… to see you suffer like this.”

Your half-lidded eyes flick toward him, lips tugging faintly upward.

“That almost sounded like you care.”

His eyes narrow slightly, but his hand lingers on the side of your head, thumb grazing lightly against your temple. His expression doesn’t change, but the stiffness in his movements betrays him.

At last, he pulls back, settling his hand into his sleeve.

“…Rest, and recover. I will not leave until you do.”

When you drift into sleep, Kokushibo remains—motionless as a statue, but unblinking, watching over you as if daring the fever itself to try and take you from him.

⋆˚࿔ DOUMA

The sound of soft footsteps and an airy hum announce him before he even enters. Douma slides the shoji open, rainbow eyes glittering as he beams.

“Ahhh, _______! I’ve brought tea, gossip, and a few jokes to brighten your day!”

He struts in with his usual flourish, carrying a tray stacked with treats and flowers. But as his gaze falls on you—slumped weakly against your bedding, skin pale and lips dry—his grin falters.

The tray lowers slightly in his hands. For the first time, his voice softens.

“…Oh.”

You cough, trying to wave him off.

“Douma, don’t… I probably look awful right now.”

He sets the tray down without a word, the clatter uncharacteristically careless. In an instant, he’s kneeling beside you, a hand hovering just above your flushed cheek before finally settling there. The cheery mask he always wears doesn’t disappear completely, but it wavers, his smile trembling at the edges.

“You’re burning up,” he murmurs, almost too quiet to hear. “Why didn’t you tell me sooner?”

You laugh weakly, though it quickly dissolves into another cough.

“Didn’t want to bother you.”

His brows knit, eyes flickering with something unfamiliar—something dangerously close to fear. He adjusts the blankets around your shoulders, tucking them carefully.

“You could never bother me. Not like this. I… I don’t like seeing you suffer.”

For once, there’s no sing-song lilt, no exaggerated cheer. Just raw honesty slipping past his mask.

You smile faintly, half-dazed.

“You’re sweeter than you let on.”

His lips part, like he wants to protest, but he closes them again. Instead, he presses a cool hand to your forehead, eyes fixed on you with a strange, quiet intensity.

When you finally drift into sleep, you don’t see him sit there motionless, unblinking—his usual smile gone entirely, replaced with something heavier.

⋆˚࿔ AKAZA

Your fever keeps you pinned down, beads of sweat clinging to your skin as you cough into the blanket. When you force your eyes open, Akaza is already there—kneeling at your side, brows furrowed into a deep frown.

“You shouldn’t have let yourself get this bad,” he mutters, voice low and tense. “You’re trembling like you can’t even hold yourself together.”

You give him a weak smile, though your voice is hoarse.

“I’ll bounce back… it’s just a fever.”

He doesn’t smile back. His jaw tightens, golden eyes scanning every detail of your face like he’s searching for something more dangerous than an illness. With surprising gentleness, he presses the back of his hand to your forehead. The heat under his touch makes his frown deepen.

“This isn’t ‘just’ anything. Your body’s fighting hard. You… shouldn’t have to go through this.”

You blink at him, startled by how raw his tone sounds. For a second, he almost looks… lost. Like he’s seeing someone else entirely.

A strange ache twists in his chest—a quick flash, like he’s knelt like this before. Sitting at someone’s bedside, worrying, tending to them. A weight of familiarity that makes his throat tighten.

He shakes his head sharply, as though banishing the thought. His hand lingers at your temple, thumb brushing lightly against your skin.

“I don’t know why, but… seeing you like this… it makes me want to fight something I can’t even see.”

Your lips part, stunned at the slip of honesty. You try to speak, but he hushes you, adjusting the blanket higher over your chest.

“Save your strength. Don’t talk. Just rest. I’ll make sure nothing happens to you.”

The promise hangs heavy in the air. When your eyes flutter closed, Akaza stays exactly where he is—kneeling at your side, one hand still hovering near yours, his frown deepened not with anger this time, but with worry he can’t explain.

⋆˚࿔ SEKIDO

You’re curled up in bed, fever burning through your body, a harsh cough rattling your chest. The sliding door slams open, and Sekido storms in, staff sparking faintly with electricity.

“Tch look at you! Pathetic! Can’t even stay on your feet because of some stupid illness?!”

You groan, pulling the blanket higher over your head.

“You don’t exactly sound worried…”

His jaw clenches, eyes blazing. He stomps closer, yanking the blanket down just enough to glare at you directly.

“Of course I’m worried, you idiot! Do you think I’d waste my time standing here if I wasn’t?!”

The words come out like thunder, but his hand betrays him—it presses against your forehead, lingering longer than he probably means it to. He jerks it back almost immediately, face twisting at the heat radiating off you.

“Damn it… you’re burning up. Why didn’t you say anything sooner?!”

You smile weakly, your voice barely above a whisper.

“Because you’d just yell at me like you are now…”

He freezes, expression cracking for just a moment. His grip on the staff tightens, shoulders trembling with the effort to hold back what he really feels. With a sharp exhale, he adjusts the blanket carefully around you again, almost tender despite his scowl.

“You… you better not die on me, got it? I won’t forgive you if you do.”

Your tired eyes meet his, and you manage a small smile.

“That sounded a lot like… you care.”

His face goes red instantly, his teeth gritting.

“Shut up and sleep before I change my mind!”

He turns away, pacing furiously at the edge of the room. But no matter how many times you drift in and out of fevered dreams, every time you open your eyes, Sekido is still there—arms crossed, jaw tight, guarding you like a storm waiting to strike anything that dares to get close.

⋆˚࿔ KARAKU

You’re lying weakly in bed, body aching with fever, when the shoji door slides open. Karaku saunters in with his usual grin, his giant fan resting lazily against his shoulder.

“Aww, poor thing. You look like you’ve been through hell. Guess it’s my job to cheer you up, huh?”

You give him a tired smile, voice hoarse.

“You’re… way too chipper for this.”

He chuckles, crouching down beside you. At first, it’s the same playful act as he fans you lightly, teasing.

“See? I’m like your personal breeze. Bet that feels nice, yeah?”

But then his grin falters as his eyes actually take you in. Your flushed skin, trembling hands, the weak rise and fall of your chest. The fan lowers slowly. For once, he doesn’t laugh.

“…You’re really burning up.”

His hand, calloused but surprisingly gentle, presses against your forehead. He frowns—an expression rare on him.

“Damn. You weren’t kidding… You’re in rough shape.”

You blink up at him, surprised by the shift in his tone.

“…Is Karaku actually worried about me?”

He scoffs lightly, cheeks coloring just a bit as he adjusts the blanket snugly over your shoulders.

“Don’t sound so shocked. I like you, you know. What’s the point of all the fun if you’re not around to share it with me?”

Your lips twitch into a small, sleepy smile.

“That… almost sounded serious.”

He laughs, softer this time, brushing a strand of damp hair from your forehead with unusual care before caressing your cheek.

“Don’t tell the others, okay? I’ve got a reputation to keep.”

When you drift off again, the faint breeze of his fan continues to cool your fever. And though he keeps his grin, his eyes stay fixed on you—troubled in a way he doesn’t want anyone else to see.

⋆˚࿔ UROGI

You’re bundled in blankets, coughing weakly, your face flushed with fever. The shoji door slams open, and Urogi bursts in with a booming laugh, wings flaring wide.

“HEYYY! Who said you could go and look like you’re dying without me around?!”

You groan, dragging the blanket over your head.

“Urogi… too loud…”

He crouches beside you, his taloned arms resting against the tatami as he leans close. That wide, sharp-toothed grin beams down at you.

“Don’t look so miserable! You’re tougher than some little fever, right?”

But when he really looks at you—your trembling lips, shallow breaths, and how your hand barely clutches the blanket—his grin falters. His feathers twitch restlessly, wings folding in tighter.

He lowers one long, clawed hand carefully, hesitating before letting the back of his talons brush against your cheek. The touch is cool, feather-light. His eyes widen at the heat radiating off your skin.

“…You’re on fire. That’s… not good at all.”

Your weak smile peeks out from under the blanket.

“What’s this? Urogi actually… worried?”

He huffs, cheeks coloring faintly as his grin wobbles back into place.

“Huh, don’t say it like that. I just don’t like seeing you quiet. You’re supposed to laugh at me, tell me I’m too loud. Not… lie here like this.”

The corners of your lips curl tiredly.

“Then… don’t leave me alone.”

Something shifts in his gaze. For once, his grin isn’t loud or sharp—it’s small, fragile. He crouches lower, wings curving around you protectively.

“…Fine. I’ll stay right here. No one’s getting near you while you’re like this.”

When you finally drift to sleep, his talons remain curled gently against the edge of your blanket, as if anchoring you in place—keeping you safe through the night.

⋆˚࿔ AIZETSU

The fever has you curled on your side, shivering despite the mountain of blankets pulled over you. Every cough shakes your whole body, leaving you drained and aching.

When the shoji slides open, Aizetsu steps in slowly, his expression already heavy with worry. His eyes soften the moment they land on you, and his lips pull into a trembling pout.

“…You look so unwell. I hate it. I hate seeing you like this.”

You manage a weak smile, voice scratchy.

“Don’t… don’t look so sad. It’s just a fever.”

He kneels beside your futon, hesitant at first, then reaches out to gently adjust the blanket higher up your shoulders. His touch is feather-light, careful as if you might break. His brows furrow deeper as his hand brushes your damp forehead, feeling the heat of your skin.

“No… it isn’t just a fever. Not to me. Every sound you make… it hurts me to hear it. I can’t stand watching you suffer.”

Your eyes flutter, warmth pooling in your chest at how openly his voice cracks. You give a soft little laugh, though it quickly turns into a cough. Aizetsu immediately steadies you, a hand hovering at your back without pressing too firmly.

“Don’t push yourself,” he murmurs. “I’ll take care of you.”

You blink up at him, half-dazed with fever.

“You… really mean that?”

His cheeks tint pink, and he looks away shyly, but he doesn’t take his hand from your shoulder.

“Of course I do. I may be sorrow itself, but when it comes to you… I just want you to feel safe. To feel better.”

As your eyes drift shut, you feel him carefully shift closer, his sleeve brushing your arm as he sits vigil at your side. Aizetsu hums softly under his breath—a low, steady sound to soothe you as you fall asleep.

And when you stir in the night, you find his hand resting lightly over yours, his gaze still fixed on you with quiet devotion.

⋆˚࿔ ZOHAKUTEN

You’re curled up beneath layers of blankets, skin burning with fever. Your coughs echo softly through the room, leaving you breathless.

The shoji slams open with a sharp crack, and Zohakuten storms in, hands clenched into fists. His eyes blaze with fury as his gaze falls on you.

“What is this nonsense?! Who dared do this to you?!”

You blink up at him weakly, lips parting in confusion.

“It’s… just a fever, Zohakuten. No one did this.”

His expression twists, teeth bared. He stomps closer to your futon, glaring down at you as if the sickness itself is his sworn enemy.

Another cough racks your chest, and you wince, squeezing your eyes shut. Immediately, his anger falters. He kneels down, tugging the blanket tighter around your trembling frame. His movements are rough, almost frantic, but undeniably protective.

“…I don’t like this,” he mutters, voice quieter. “I hate seeing seeing you like this. It makes me angry. I want to destroy it. I want it gone.”

Your tired eyes meet his, and despite your fever, you smile faintly.

“That’s sweet… in your own way.”

His cheeks flush instantly, and he scowls harder to cover it.

“I’m not being sweet! I just… I just don’t want you to disappear. If you did, I’d—”

He cuts himself off, fists clenching at his sides. His face twists between fury and something softer he refuses to admit. Finally, he huffs and sits cross-legged beside your futon, glaring at the floor.

“Rest. I’ll stay here. If this sickness tries anything else, I’ll crush it myself.”

You giggle weakly, and his eyes flicker to you, softening for just a moment before narrowing again. He stays there, silent and stubborn, but his hand eventually finds its way to rest lightly over yours—hot with fever, but safe under his watch.

⋆˚࿔ GYUTARO

Your fever has you curled weakly under the blanket, coughs scraping your throat raw. Every breath feels heavy, and your skin burns hot.

From the corner, Gyutaro watches. His lanky frame is hunched, yellow-green eyes narrowed as his nails scratch absently at his skin. He clicks his tongue, voice dripping with bitterness.

“Heh… look at you. Perfect even when you’re sick. Figures. Meanwhile, l’m the one stuck watchin’ you suffer.”

You give a weak chuckle, though it dissolves into another cough.

“You don’t… have to stay. You don’t like looking at me like this.”

He flinches at your words, then scowls, crouching down beside you. His voice grows sharp, but his hands betray him as he tugs the blanket back up over your shoulder with surprising gentleness.

“Shut up. Don’t tell me what I like. You think I wanna see you all pale and burnin’ up like this? You think I enjoy it?”

His eyes dart over your face—every shiver, every labored breath. His chest twists painfully, like the sickness is gnawing at him too. He mutters, more to himself than to you.

“Damn thing doesn’t even care how good you are… it just eats away at you.”

Your lips curve faintly, even through the fever.

“…You care more than you admit.”

His cheeks flush instantly, and he bares his teeth to hide it.

“Heh.. don’t say crap like that. You’re delirious.”

But his hand doesn’t move from where it lingers, hovering at your temple before finally brushing damp hair from your face with the lightest touch. His voice drops lower, rough and raw.

“…Just get better, okay? Don’t leave me here with nothin’.”

When you drift into sleep, you don’t see him bow his head, his long hair shadowing his expression. His nails twitch like he wants to claw the sickness out of you himself, but instead, he just keeps petting your hair in shaky, uneven strokes, staying by your side through the night.

demon slayer masterlist

Can I also request for some headcanons? Uppermoons, Muzan and yoriichi with a s/o who feels the aggressive affection towards them? Like how we normally feel with cute things or the person we love and would out of nowhere hug them tightly, cooing and squealing sweet words or just bite them— like on cheek or arm?

I’m so so soo glad you liked it !! And I simply loveeee the idea !!! I believe my love language is actually aggressive-affection lol thank you so much for requesting it I’ve never thought about it before !!

𝐊𝐍𝐘 𝐌𝐄𝐍 𝐖𝐈𝐓𝐇 𝐀 𝐒/𝐎 𝐖𝐇𝐎 𝐅𝐄𝐄𝐋𝐒 𝐀𝐆𝐆𝐑𝐄𝐒𝐒𝐈𝐕𝐄 𝐀𝐅𝐅𝐄𝐂𝐓𝐈𝐎𝐍 𝐓𝐎𝐖𝐀𝐑𝐃 𝐓𝐇𝐄𝐌

𝐏𝐚𝐢𝐫𝐢𝐧𝐠 : Upper Moons (1-3) ; Gyutaro ; Muzan and Yoriichi.

𝐂𝐎𝐍𝐓𝐄𝐍𝐓 𝐖𝐀𝐑𝐍𝐈𝐍𝐆 ʚɞ : None ?

𝐌𝐔𝐙𝐀𝐍 𝐊𝐈𝐁𝐔𝐓𝐒𝐔𝐉𝐈...

The GIF speaks for itself he's pissed lol... but secretely likes it.

At first he was just so flabbergasted like genuine shock.

"Why are you...squealing ? And biting me for... ?!"

He would often freeze anytime you'll attack him with those then relax.

He would sometimes grith his teeth or gruff in annoyance but notice how he lets you ?

He got so used to it that it became so predictable.

He'll just start dodging your bites attacks or anything that could physically "cutely harm" him when he feels like it.

Just to annoy you.

He likes the hugs the most. (But would never admit it even if you threaten to bring back Yoriichi to life)

Despite the scowl, he never steps back. His arms twitch like they want to hold you. But they never do. Not yet.

"Enough."

"But-"

"That's the 113th space invasion of the day"

"Well talking about personal space, you did invide Ubuyashiki's mansion-"

"That's diiferent-"

"That's space invasion still."

"..."

He braced himself for the 114th one...

𝐘𝐎𝐑𝐈𝐈𝐂𝐇𝐈...

Literally lets you tackle-hug him mid-battle and just smiles. 🥺

The first time you bit him, he paused before gently laughing like : "That was unexpected..."

He finds your affection healing. After leaving a life of lonliness, your love and presence feels like a new light.

THAT MAN BLUSHES!

Every time you would bite his cheek or arm he would look confused, then blush, processing what you just did.

"Is this your way of showing fondness?"

His responses are always innocent, trying to understand the why you did that.

He finds it really cute.

He'll quickly get accustomed to it and will do the same.

He doesn't even resist or show any negative feelings toward it, while he's usually the composed and soft one, a bit of lovely chaos in his life is not for him to refuse!

But he'll be more on the gentle clingy side not straight out aggressive.

He'll hold you close, cage you in between his arms cooing at you, trying to make you laugh and never let go.

He's like a golden retriever, always ready for your little stunts and never gets tired of them.

"You are the most curious soul I've ever met. Please stay the way you are..."

𝐊𝐎𝐊𝐔𝐒𝐇𝐈𝐁𝐎...

Completely shaken.

Your random tight hugs or kisses on his cheek leave him STUNNED.

"Is this… affection? I am… not accustomed to such warmth."

He’s still learning how to interpret physical affection (MY SHAYLAA)

He doesn't really know how to return that much energy at first, he's used to being calm and composed so having an energetic s/o like this completely shatters that part of him.

He would be lying if he said he didn't like it.

The first time you bit him oh THAT MAN FLINCHED.

Not because it was painful but because never in centuries someone had done that to him EVER.

He's sooo touch starved but has no idea know how to initiate, so deep down he's very thankful that you're the one initiating it.

He would act like he doesn't like it at first. But secretely loves it!

He tried to bite you in return once, little did he know he created a kink.

Sometimes when you go under his radar and manage to "surprise" him, all six eyes blink slowly, staring down at you.

Processing your affection like it’s a puzzle before relaxing and sighing. (I promise he loves it tho)

*sees you approaching in his periphical vision*

"Don't."

"I haven't done anything yet!"

"You were going to."

"I wasn't...well okay please just one more bite-"

*he teleported somewhere far away from you*

𝐃𝐎𝐔𝐌𝐀...

ABSOLUTELY LOVES IT.

Finally someone who matches his energy!

Whereas bites, squeals or hugs he loves them all!!

He would wrap his arms around you and spin you in response everytime, with both of you squealing like idiots.

It's like a never ending mix of fun and banter.

He exaggerates every reaction just to make you laugh.

You would kiss his cheek ? He would fake-die dramatically.

The first time you bit him he just paused like "...", before smiling creepily.

And right there you knew you were done for...(Run if you still can..)

You're both biting each other now and he clings to you any chance he gets.

And that shi hurts fr tho like have you seen those FANGS ??

But deep inside… that affection means everything. He never had love like this.

"You know you can't hide from me right ? No matter where you are I'll always find you ~ My bites don't even hurt that bad I promise I won't bite you this time! I just want to feel you close again." he coos, looking for you.

"There you are."

"DON'T-"

*bite*

𝐀𝐊𝐀𝐙𝐀...

He would FREEZE then relax.

His body just naturally tenses at any contact after being so conditioned to react quickly if any fights were to occur.

You would bite his cheek softly and giggle. And he doesn’t react. Not at first. Until he exhales and whispers, (more to himself) "You’re dangerous…"

Not because of your strength, but because of how easy it is for him to let his guard down around you.

Over time, he starts seeking it.

And he'll start living for it. He acts like he’s unfazed but he adores how affectionately feral you are.

Like you could literally lunch yourself at him and he would catch you like it’s the most natural thing in the world.

And if you ever stop being aggressively affectionate — if you go quiet one day, that’s when you’ll realize how much he craves it.

"Hey. Bite me or something. I’m starting to think you’re mad at me..."

𝐆𝐘𝐔𝐓𝐀𝐑𝐎...

He literally glitches like Muzan but worse. Affection?? For him???

If you bite his hand or cheek teasingly, he stares like you just unlocked a secret part of him.

"Wh...what are you doin’? Stop that! …No wait… don’t ?"

He thinks you’re making fun of him at first.

But when you kiss his scars like they're the most beautiful piece of art or call him cute names, he just melts.

Understanding that what you're showing him is just pure energetic affection and not mocking in any way, just a new kind of affection he never had access to before.

He would look away and blush at every cheek kiss or bites, feigning annoyance, muttering under his breath as if he wasn't craving it.

At first, he wouldn't know how to say thank you or reciprocate this aggressive affection.

So he would let you do it again. And again. Until it feels safe.

He eventually starts biting you back, but gently of course he's quite aware of his fangs ( *cough* not like a certain cult president) and playfully. His excuse ?

"Well YOU started it..."

✎ 𝒂kaza 𓂃 ♡︎ the shrine had long since lost its holiness. once, maybe, people had come here with prayers, with offerings, with trembling hands clutching candles and coins, whispering for blessings into the air. but now the roof sagged under the weight of moss and rain, wood split open by years of rot, the altar cracked and jagged like teeth. it smelled of mildew, of damp stone, of something long forgotten. when you stepped past the broken gate, it felt like walking into a mouth that meant to swallow you whole.

you told yourself you came here to investigate, to track whispers of demons prowling in the area, to follow duty where it called. but the truth slipped into your mind, unshakable—you shouldn’t be here. not alone. not in the silence of night, where even the wind dared not move through the trees. the stillness pressed on you, heavy as a weight on your chest, until the fine hairs at the back of your neck prickled.

that was when he appeared. you didn’t see him walk in. you didn’t even hear the floorboards creak. you just felt it first—the crushing weight of presence, like the air had turned to stone, like your lungs forgot how to breathe. akaza stood where the moonlight bled through the broken roof, tattoos glowing faintly under pale light, eyes sharp, unblinking, unhuman. his voice cut the silence, low and steady, carrying a cruel amusement.

“hm. another slayer wandering in where they shouldn’t. fragile little thing… you really thought you’d make it out of here alive?”

your sword was already in your hand, heart hammering as you forced your body into motion. you lunged first, trying to seize control, trying to bite down on fear and twist it into strength. the blade sliced toward him—but it never landed. his hand lashed out, faster than thought, knocking steel aside as if it were nothing more than paper. his other hand clamped around your wrist, fingers digging so deep you swore he could crush bone if he wanted.

you jerked, twisted, fought, but it was useless. his strength was overwhelming. before you could gasp, your back slammed against the cracked altar, the sharp edge biting into your spine. the impact knocked air from your lungs, leaving you gasping like a fish on land. your blade clattered across the broken floor, useless.

akaza’s grin stretched slow, wolfish, as he leaned close enough for his breath to ghost against your face. “you fight with spirit,” he murmured, grip tightening when you tried to squirm free. “but spirit won’t save you. not when you’re this weak. not when you’re this breakable.”

you're meant to be a lowermoon, just a bit weaker than Enmu. yet you're prioritized like you're muzan's strongest soldier. whenever there is danger you're never sent to deal with it, instead, you stay by muzan's side. you mostly just...follow him around?

you're even in the uppermoon meetings, if someone points it out Muzan tends to shut them up. he mainly has you sit near him, never near the others. you were not punished when Rui had died like the others, far from it.

he also doesn't seem to care when you speak out of turn, whether it is just saying you're hungry or to give an offhanded comment to get an uppermoon seething. he just pats your head like nothing's wrong, or sometimes even nods.
