Hannya Mist | Giyu Tomioka x demon fem!reader

Warnings: aphrodisiac (kind of?), touching, boobs, Giyu's first time seeing boobs (#I'm so proud of him), fight for control, first blow job, mentions of sexual fantasies, and mortal enemies kind of sexy for each other heheheh word count: 2.1k a/n: Giyu... my baby. Virgin just fits you so perfectly, but when you learn you LEARN.

Fireflies float through the air, the footprints left behind by the water hashira marking a path of determination. The evening air is muggy, nearly oppressive as Giyu comes across a strange hut. It’s a small building, barely bigger than a room at the water pillar’s manor. His aqua gaze searches for evidence of a nearby village. It was off to have a hut in such a dangerous part of the woods. Did anyone even live in it? If it were abandoned, he could rest up under its roof for the night.

As if answering his inquiry a light flicks on, illuminating the silhouette of a woman in the window. The mountains swallow the rest of the sunlight, a dim stillness settling in the clearing where Giyu stands stagnant. The water pillar is unaware of the mist swallowing him up. A deep purple fog coats the surrounding area, the tendrils from the mist seemingly beckoning him toward the hut. 

Come closer it almost whispers and against what better judgment he could form through the thick fog – coating his throat and sense of smell – he takes a heavy step forward. His heart is racing despite the calm breeze that rustles the leaves above his head. Dusk painted the sky an array of orange and pink. 

It was like he was on the brink of suffocating. What was with this air anyway? Had it always been this stifling? Giyu sucks in a steady breath, the purple mist filling his lungs. He feels a tingle in his lower abdomen and his brows furrow as it burns hot, making him take pause in his advance toward the hut. 

His limbs feel shaky as he brings a hand to his forehead. His other hand grips the hilt of his sword as if that would stop him from sinking to his knees. The slick magma grows, tying his muscles in a buzzing feeling that nearly makes him want to rip it out. He’s panting, the hand that was on his forehead dropping to his mouth as he bites down on a finger. 

Giyu Tomioka, the stoic and quiet water hashira, was unnervingly horny. He could feel himself grow stiff in his breeches. His throat bobs as he shakily shifts his legs apart to allow more room for his swelling cock. He’d never experienced such an overwhelming sense before, only hearing about it from the other hashira. Sex never interested him, it was a distraction from the ultimate goal of destroying all demons – but as his eyes flutter shut, all Giyu wants to do is find a wet warm cunt to plunge his aching cock into. 

Night has captured the clearing, dusting the ground with moonlight. With the way he felt now, it wouldn’t be safe for him to enter the hut. Not with a woman supposedly alone inside. This damn fog was making him crazy, but the damned door swings open, revealing you.

His hand releases the hilt of his blade.

You are in a blush pink yukata, hands folded in front of you, and a hannya mask covering your face. Your hair flutters around the mask, your head cocking to the right as you peer through the small eye holes at the encumbered water hashira. Beneath your lips pull tight into a smirk. 

Giyu had a string of thoughts enter his head, one specifically that he would surely spend the rest of his life wondering about. What did you look like under that mask? A mask crafted to take on the appearance of a female demon consumed by jealousy. Your mask is made out of wood, the bark left jagged and dangerous. Two pointed horns sprouted from the sides, weaving into your own hair. The brows are drawn together in protruding masses. Sharp teeth decorate the open mouth that’s under a large nose. 

The water pillar takes a tentative step forward, your presence calling him into your den. “Excuse me, miss, I don’t mean to intrude, but I’ve had a long journey.” He pauses, his head spinning with obvious reasons as to why he should not enter your hut. 

You step to the side, though, slowly righting your head. “You need a place to rest. To be safe from demons.” The mask muffles your voice, but Giyu revels in the way its melodic tone enters his ears.

Just for a little bit, he promises himself. The water hashira enters through the threshold of the hut. Inside is a raised wooden platform with a mat pushed into the corner – folded bedding placed on top neatly. Beside the mat is a small table with a candle and tray of steamed rice, vegetables, pork, and a cup of piping hot tea. A cushion rests directly in front of the table, a rug underneath that. In the middle of the dirt area is a cooking pot – storage closets lining the wall and a flickering orange lantern that lights up the whole room on a bench. 

His eyes flick to how you stand by the door – he only assumes you’re still watching him by the way the mask faces his general direction. “Have I interrupted your dinner?” His voice is soft and playful. 

You shake your head gently so as not to disturb the placement of your mask, then step toward him. “Dinner has just begun.” You reply, gesturing to the steaming food with your head. “Please, eat.” 

The ravenette’s mind is fuzzy as he sets his nichirin sword against the far wall. Then, slipping out of his zori, he steps onto the wooden platform. He’s surprised by how comfortable the cushion is under his knees. The food looks delicious, but he stiffens when you come to kneel next to him. Your body was mostly hidden by the yukata, but the hashira imagines how exactly he would lavish you – if he knew how. 

He’s stricken with shame – for having such thoughts with you next to him and for his lack of knowledge about sexual experiences. He was disciplined in how the body functioned, training for years on how to perfect muscle density and stances. He clears his thoughts of the wicked images, picking up the chopsticks that are next to the bowl of rice. “Thank you for the food,” He takes a mouthful of rice, humming in satisfaction at the warm consistency. Giyu peers at you while chewing away on the food. “If you do not mind me asking, why do you wear such a mask?” He was genuinely curious, but then again, he was curious why you had to be clothed as well. 

You tilt your head. “To hide my identity. Safety.” You answer and as Giyu swallows another mouthful of rice he feels that sickening feeling return. This time it feels like it’s coursing through his very bloodstream. He sets the chopsticks down and you lean forward, raising your hand to pull your mask down. “Are you okay my Lord? That is what they call you right?” Vibrant eyes narrow at him and fangs accompany the twisted smile on your face. 

Giyu is panting, clutching his throat as it burns with sensations foreign to him. “D-demon,” He begins, lips curling in disgust. “What did you,” He hacks up spit and winces at the fire in his esophagus. “Do to me?” 

Your lips curl in a smirk, crawling closer to him. Giyu can’t move back as you slither toward him, placing your clawed hand on his thigh. “Mmm, well I’m not the one lusting after a stranger.” You tip your head to the side curiously as you graze the indent of his bulge. The ravenette hisses at the way he shifts into your touch. This earns a delighted laugh from you. “I am a demon, the thing you promise to eradicate from this plane of existence, yet you yearn for my touch. It’s…adorable.” Your fingers press firmly into his erection now, Giyu’s eyes squeezing shut. 

His body feels like it’s being electrified as you trace the imprint of his cock. “You-You did this to me,” he grunts out. The fog must’ve had some sort of aphrodisiac in it. He’s full of rage and disgust, but also lust. 

You giggle, meeting his heated gaze – the blue in his eyes darkening to almost black. “Yeah? Doesn’t look like you want me to stop,” Your fingers reach for the hem of his breeches. “You smell like you’re on the verge of cumming. Are you pure?” Giyu’s heart thumps wildly in his ribcage as you drag your nose up his neck, your tongue darting out to taste the line of his jaw. You return to his line of sight with a wide grin. 

The water hashira’s cheeks warm with the acknowledgment. “Please, help me.” You almost want to take pity on the whimpering man in front of you, but who’s to say once your mist fades away that he won’t drive that pretty katana through your heart? He was… exceptionally fit and had withheld this much torture. 

You start to peel off your yukata, edging the sleeves down your shoulders. “If you don’t satisfy me, I’ll kill you.” Giyu’s skin itches to be warmed by yours as the yukata billows to the floor. He’s never seen a demon become shy, but that could be a result of him gawking at your large breasts. The way they rest on your chest brings his gaze down to your navel, then dips to your thighs that press together. 

After a beat of him staring, you grab his hand and place it on your chest. His brows furrow as the skin molds around his thick fingers. Your own brows knit together as a stained moan escapes your lips. “Barely started and you’re already a mess,” Giyu quips, growing more comfortable with the way your nipple brushes against his palm as he squishes your breast. 

You huff, positioning yourself closer. “It’s just been a while.” The hashira tuts as his fingers find your nipple, rolling it between the pads of his thumb and pointer finger. You throw your head back and groan. “Fuck,” 

He was growing confident and he hadn’t even gotten to the finale yet. You reach out to stroke his thigh, a smirk twitching on your lips. His ministrations halt, moving his arms out of the way so you’ll have more room. Your ears pound as you gaze upon the sheer size of his cock and some of it was hidden underneath the cloth of his breeches. He gets up on his knees, working them off his hips. Hard pelvis lines lead to the star of the show – the untouched cock of the formidable water hashira. It is fucking beautiful. A pale pink head that’s leaking precum and a hungry look in his eyes. 

Though the very thought of having a demon’s mouth around his cock should seem like a very bad idea, Giyu runs his hand through your hair, fisting around it. “You’re gonna wrap that pretty mouth of yours around my cock. Got that, demon whore?” 

To you, that should sound like a threat. You should kill this hashira and reap the rewards, but you allow him to push your head down to his stiff length. For someone who was supposedly pure, he acted like he’d done this before. 

The moment your hand wraps around him, his eyes roll back in his head. It’s glorious, the feeling of your palm against his length, pumping up and down. He goes wild when you graze the slit of his tip, rubbing the pre along his cock. Without warning you dip your mouth onto his tip, using the flat of your tongue to swipe at the vein running up the underside. He groans, shoving your head further down. 

Hearing you sputter and choke on his cock is damn near hell sent. Spit drips from your mouth and warmth radiates from you trying to breathe. He’s hitting the back of your throat, your fangs dragging along the side of length. Giyu shivers, the feeling painfully pleasurable mixed into a bowl of fucking salvation. 

“M’so close,” There’s a fire located in the pit of his abdomen and maybe this is where demons are born – in this hell of angelic desire flooding to one place. That one place happens to be your mouth as Giyu jerks his hips up into your mouth, cumming hard. Spittle and his creamy mess mix as he pulls your mouth off him. 

Of course, you lick your lips and swallow what you can with a swollen smirk, but that falters when you realize he’s orgasmed. The one thing to break your mist is to feed into the desire. That would mean Giyu is clear of mind and probably going to cut your head from your-

His hand wraps around your throat, shoving you to the ground. He hovers over your naked body, panting crazily. “My tricks seem to have run dry,” You garble out. 

Giyu clicks his tongue, gazing down at your plush skin, regarding the view. “Ah, but I’m not finished yet, demon.” 

HEHHEHEHEHEH WHATS UP MY BBG? I hope you have had a good day/night! I have this idea in my head that I'm ITCHING to get out but you can feel free to ignore❤️

Can you do what would happen and what would Sanemi, Giyu, Tanjiro, and Obani do if reader got turned into a demon during a battle?

LIKE I SAID FEEL FREE TO IGNORE!! YOU DA GOAT BBG❤️

GEHEHE I'M DOING SO GREAT! 🫶🫶I HOPE YOU'RE DOING EVEN BETTER THOUGH 😡🥹 It was raining here all day and I was a worrisome parent and got soaked going to check on my kitties🥰🥰. (also why would I ignore such an angsty request MWAHAHA😈)

Includes: Sanemi Shinazugawa, Giyu Tomioka, Tanjiro Kamado, and Obanai Iguro CW: pretty much reader dies in all scenarios, but... yeah no my heart hurt writing these so there's no hope for any of us. Death, angst, sadness.

Sanemi Shinazugawa

The demon’s claws slice through you, tearing your skin apart. You fall to the ground, crumpled and bleeding

“San-Sanemi,” You choke out, the life draining from your beautiful eyes.

A vengeful scream erupts from his throat, burning his very vocal cords as he rushes the creature

Its head falls to the ground with a gruesome thump, Sanemi dropping to his knees next to your corpse. “YN...I’m so-”

Your eyes, they’re open and your pupils pull into slits. His next breath catches in his throat. “Sorry,” He breathes, his eyes stinging with hot tears

He picks up his nichirin blade, using it to help him into a standing position. Sanemi’s choked sobs echo through the forest valley. The glint of fresh sunlight reflecting off of his blade as he plunges the tip into your heart. The sun is cresting over the mountains in a new dawn.

Your garbled noises nearly drive him to the brink of whisking you off to a shadowy haven, but you wouldn’t want to live out your life being the very thing you fought so hard against. 

As the ashen belongings of your body blow past him he feels like he’s just stabbed himself through the heart.

“Sorry…so sorry.” He cries, but the sunlight dries his tears. 

Giyu Tomioka

He was by your side one second then cornered off by a second demon. He wants to remain close to you and protect you, but as he lands the final blow to the demon in front of him he catches the tail end of the demon lifting you by your throat. 

His blood runs cool, the demon’s features twisting in a cruel sneer as it makes you lick up the blood from his wounds. 

Too late, too late, too late

Just like with Sabito, Giyu was too late to save you. His head spins, running through possibilities to somehow not fuck up again

Tanjiro and Nezeko were a special case, who’s to say Giyu would break through to you? And when he didn’t? Would his heart finally go numb? The risk was too great.

The demon has dropped you and ran off, leaving you panting on the ground. You touch your throat, hacking up the blood it tried to feed you. A glimmer of hope sprouts in Giyu’s chest. Maybe you had saved yourself? You meet his gaze, tears rolling down your cheeks.

“Giyu,” you smile, the one he’d grown accustomed to seeing every morning when you greeted him. “Giyu, I need you to be strong,” you start, but he can’t hear you. He doesn’t want to.

“No, I’m not strong,” His voice is trembling. His body aches with the knowledge of what you’re about to request of him. He couldn’t do it. You meant too much to him and he was a selfish man. When everyone else ignores him you see through his suffering to the little boy underneath, scared of being seen for the fraud he was. 

There’s that smile again. “Giyu. You’re a Hashira, you’re more than strong – you’re kind. You know what you have to do. Please, before it’s too late.”

Giyu’s body feels limp as tears mix with his sweat. He was too weak to save Sabito, but he could still save you. He yells into the night, a pained scream that rustles the birds from their branches.

Your head thumps to the side, fanning into dust as he sinks to his knees, sobbing over your remains. Turns out – he wasn’t numb after all. 

Tanjiro Kamado

You’re bloody, a demon standing over you, it’s foul stench dripping round droplets onto your wound

“Let’s see if you have the heart to kill one of your own, slayer.”

Tanjiro had been through this before, with his younger sister Nezeko and things were turning out alright with her.

Would his bond be strong enough to snap you out of the demonic craze? You had acted like an older sibling to him, watching over his progress and always cheering him on. Often he thought the gods had blessed him with you so he would have someone to look after him when he had no one. 

“YN!” He screams, the demon slipping away into the night. “YN talk to me. If you can still talk that means there’s still time.” But the veins on your face bubble and contort your expression to one of hatred.

Tanjiro falls back on his hands, heart loudly echoing in his ear. “YN, please… it’s me…your little brother.” But it’s far too late to work on your once human heart. As you rise to your feet Tanjiro stumbles to his as well

His katana is shaking in his grip. You were a demon, but also his friend. He can’t see through his blurry vision. 

“Pathetic,” you spit, then before Tanjiro can will his heart to do what he knew he couldn’t, you spill into the shadows

His vow to cut the head from Muzan Kibutsuji’s body grew a thousandfold that night

Obanai Iguro

You had been on this mission for weeks now, fighting side by side. Obanai had grown fond of you.

That was until a demon stole you away, reminding him that fondness sprouted weaknesses. However, he tracks you down regardless.

The demon had set up in a cave, the dawn making this rescue mission easier, but as he steadily slides into the heart of the cave he finds you’ve been tied up, dried green blood on your lips

“Fuck,” Obanai hisses into the darkness, searching around for the creature that did this to you

“It’s gone Obanai…” You drawl, your voice raspy and strained. He winces at the state of you.

He rushes to untie you, hoping it’s not too late and the insect Hashira can work some miracle cure on you. If Obanai was fond of you he couldn’t even imagine how the corp members felt about you. 

It had been a while of your fighting off the urge to turn, there had to be hope for you. If only he could get you back to headquarters fast enough…

As if reading his mind you shake your head solemnly. “Please, let me see the sunrise one last time,” you croak, gaze drifting to the sunlight filtering in from the cave’s entrance. 

Obanai squeezes his eyes shut, the electric buzz of his heart making it hard to fulfill your request. He was stagnant, breath quickening as you pleaded with him.

He offers you his hand, willing his chest to return to steel. He leads you to the outside world and your grip tightens as you step into the sun. Obanai’s body aches with unrelenting sorrow. If only he’d kept a better eye on you.

Soon enough, a faint ‘thank you’ blows past him on the wind, and he rushes away from the spot, not willing to look at what he had so carelessly taken for granted.
