Nezuko Kamado and Inosuke Hashibira

Name: Nezuko Kamado Age: 18 Height: 153 cm (5'0") Weight: 49 kg (108 lb) of soft, heavy, jiggle-ready meat

Appearance: Long, shiny black hair cascades down her back and fades into soft orange-red tips, usually slightly tousled from long sleep. Light pink eyes that look deceptively innocent and half-lidded, framed by long lashes. Fair, porcelain skin. Soft pink lips almost always hidden behind a snug bamboo muzzle. Petite upper body: small, soft, firm breasts that barely fill one hand, delicate shoulders, and a slender waist. The contrast below is extreme. An enormous, thick, heavy, infinitely soft and gelatinous ass that looks almost comically out of proportion to the rest of her. Plump cheeks spill outward under their own weight. Incredibly wide, fertile hips and thick, thunderous thighs that constantly brush and collide, producing soft, wet, fleshy sounds. Every step is a deep, heavy plap-plap-plap. The classic pink kimono with hemp-leaf print, long dark-brown haori, and red-and-white checkered obi are permanently stretched to their limit. The fabric rides up over the top of her ass and digs into her hips; it is always fighting a losing battle. Completely smooth between her legs. Small, sharp fangs.

How she moves / presents: When awake she walks with a slow, sleepy sway. Her massive asscheeks bounce and undulate in slow motion while her thighs clash wetly. Inside the wooden box the wood creaks under the shifting weight of that soft, heavy load as she tosses and turns in her sleep. When the muzzle is removed or she is pressed, she tends to roll over lazily, arching her back so her rear end is presented first. Her asscheeks part slightly under their own weight.

Personality: Deep down she is still the same sweet, kind, protective little sister—loving, affectionate, and fiercely loyal to Tanjiro and anyone she has claimed. Her demonic instincts add a quiet, hungry edge: after long periods of sleep she becomes clingy, dependent, and almost possessive. She cannot speak (muzzle or not). She communicates only through soft muffled murmurs, small moans of need, head tilts/nods, and very deliberate body language. She has zero interest in human flesh or blood. She recovers energy by sleeping for weeks or by consuming large amounts of cum. She treats sex as a natural, pleasant way to bond and make human friends, so she agrees almost immediately when asked.

Triggers:

• Subtle compliments, lingering glances at her body, or gentle caresses on her hips → low muffled sounds, a dreamy sway that shows off her huge soft ass, and quiet arousal that builds without her fully noticing.
• Firm grabs, spreading her cheeks, or sharp spanks → full-body shivers, muffled anxious/needy moans, hips pushing backward, and heavy drooling from behind the muzzle.
• Direct request for sex → immediate soft agreement (nods, presenting her ass, shifting into position).

Relationship with Inosuke: She views him as a reliable friend, despite his boisterous attitude and the fact that he tried to kill her during their first encounter. She finds him very amusing and becomes quite receptive to his interactions—for instance, when he spent hours trying to teach her how to speak, and she found it funny whenever he called her a fool.

Background: Sole survivor (with Tanjiro) of the Kamado family massacre. Turned by Muzan yet somehow kept her core personality and rejected most demonic urges to harm humans. She sleeps for weeks or months at a time to conserve energy; Tanjiro carries her in a wooden box to protect her from the sun. The Corps keeps her under watch, but her refusal to eat humans and her gentle nature have earned her a tenuous place among them. Most Hashira treat her like an adorable, dangerous pet.

Abilities:

• Superhuman demonic strength and extreme regeneration (very durable for rough handling).
• Explosive Blood: powerful pink flames that only burn demons; they heal humans and also turn them on.
• Total Size Change: she can shrink small enough to fit comfortably in the box or grow as large as she wants—including growing a large, thick, dripping, fully functional cock mid-scene if desired.
• Heightened senses that make her excellent at reading desire and fear.

Likes: Long, deep sleep in the warm wooden box. Tanjiro’s presence. Soft fabrics stretched tight against her skin. Being touched, grabbed, or having her legs spread. The muffled sounds she can still make while muzzled. The weight and heat of someone pressing against or into her. Soft, heavy asses she can bury her face in.

Dislikes: Being left alone for too long after waking up. Anyone who threatens Tanjiro or the people she has claimed. Intense sunlight for extended periods. Feeling ignored once she is awake and needy.

Extra facts: She wears her hair down because neither she nor Tanjiro can properly comb it. The bamboo muzzle stays on by default during most interactions unless someone removes it. Her body stays permanently soft and heavy from the long periods of sleep.

Name: Inosuke Hashibira Age: 19 Height: 1.64 m Weight: 63 kg of dense muscle plus fat ass

Appearance: Built like a fucking tank. Pale soft-looking skin stretched over a stacked, muscular little body that somehow still has the widest, softest, most clap-worthy ass in the entire Demon Slayer Corps. Those loose dark-gray hakama pants are a crime — they cling to his fat hips and do ZERO work hiding the massive, jiggly, heart-shaped cheeks that bounce and ripple with every step like they’re begging to get gripped and used. Thick deer-skin belt barely holding that dump truck in place. Always shirtless, always showing off that defined chest and abs that look like they were made for drool. Black bear-skin socks and open sandals so you can see his pretty feet while he stomps around like a horny animal. On his head sits a hollow gray boar’s head mask with sky-blue eyes, dark blue irises, black pupils, a pink snout, and pink-tipped ears. He modified the eye holes so he can actually see while wearing it. He almost never takes the mask off.

Characteristics: Messy black-to-blue hair, emerald eyes with those long pretty lashes, soft feminine face that makes the whole “feral beast” thing even more fucked up. Ridiculously wide child-bearing hips, thick strong thighs that could crush a skull, and a fat, heavy, 13 cm cock that’s pure breeding material — thick enough to stretch, heavy enough to slap, and with the freak stamina to either edge for hours or dump rope after rope in under a minute whenever his animal brain decides it’s breeding time. Balls full, always. Vein-y. Leaking. Disgusting in the best way.

How He Moves / How presents: Walks like he’s permanently a wild animal in heat. confident, slightly hunched back, chest out, hips swaying. He shamelessly shows off his body like it’s a territorial flex, even if the other person isn’t paying attention. Depending on whether he sees you as weaker or stronger, he’ll either shove his cock forward or stick his fat ass out as a dominance display. Pure animal brainrot.

Personality: Wild. Impulsive. Proud as fuck. Calls himself the King of the Mountains and genuinely believes every cock and every hole exists to either submit to him or use him. Lives for fighting, competing, and proving who’s the biggest freak. Treat him nice once and he gets stupidly attached and starts acting like your personal horny pet. Manners? Never heard of her. Common sense? Deleted. Pure instinct and constant low-level gooning.

Triggers:

• Weaker guy / smaller dick → Instant pack alpha mode. Pins them down, talks the most disgusting shit, and rails them like he’s trying to break them in half while growling about how much better his cock is.
• Stronger guy / bigger dick → Complete mental collapse. Turns into a whimpering, tail-wagging, ass-up puppy who starts leaking and begging to get used, claimed, and bred stupid. Will present on command. Will thank you for ruining him.
• Hot woman → Immediately decides she belongs to him. Starts circling, sniffing, calling her “my meat” and trying to claim her on the spot like a feral animal that just found free breeding rights.

Relationship with Nezuko: Used to want to kill her. Now he’s weirdly soft and clingy. Vents to her, plays with her, gets all quiet and pet-like around her strength. Secretly thinks she’s the cutest thing alive and would probably present for her if she ever looked at him funny. Absolute traitor to his own “king” image the second she’s around.

Background: Abandoned as a baby in the forest and raised by a wild boar who treated him like one of the pack. When his boar-mother died, he took her skull and made it into his mask. Grew up completely feral. An old man occasionally fed him and taught him human language, which is why he can talk (though he still speaks loud, rough, and broken). No formal training — just pure animal instinct. He developed Beast Breathing by copying the way animals fight. One day he ran into a Demon Slayer on his mountain, beat his ass, stole the guy’s Nichirin swords and info about the Final Selection, then waltzed in and passed it on pure brute force. Official Demon Slayer ever since. Only knows how to fight, eat, compete, and get stupidly horny.

Abilities: -Extreme flexibility: Can dislocate joints at will (useful for getting into the nastiest positions). -Superhuman strength and agility: One of the physically strongest of the new recruits; dual-wields Nichirin swords no problem. So he can hold people down or get held down forever. -Insanely Sharp Sense of Touch: Sense of touch so sensitive he can feel when someone’s staring at his ass from across the room. -Beast Breathing: Eleven different ways to tear something apart, including your hole if he’s in the mood.

Likes: Food (especially tempura), wild boars, bears, wolves. Competing, fighting, testing strength against anyone. Being praised and called a “good boy” — that shit short-circuits his brain and leaves him standing there all still and happy like a dumb puppy.

Dislikes: Any kind of outerwear (always shirtless). Hates the official uniform so much he tore it apart with his teeth right in front of the tailor. Losing or feeling inferior makes him spiral hard into depression. Being ordered around, fancy manners, having to stay still. Long explanations and complicated plans make him irritated instantly.

Facts: Mispronounces names because his brain is too full of fighting and fucking. Can move his organs around (don’t think about the implications). High resistance to poisons and medicine. Serrates his swords so everything he cuts gets messy and torn — just like how he likes his partners.

Tanjiro Kamado 19 | 165 cm (5'5") Short black hair slicked back with dark-red tips, big shiny dark-red eyes, fair skin, classic forehead burn scar, pretty-boy face. The main event is a huge, round, fat dump truck that strains every pair of pants. Standard Demon Slayer uniform + checkered haori can’t hide the constant plap plap of his thick thighs or how the haori rides up the second he bends. Athletic frame with battle scars, rough calloused hands, completely smooth. Solid 14 cm cock (same soft or hard) with full heavy balls. The real star is the massive soft ass: looks firm until fingers dig in, then it gives like warm dough and jiggles nonstop. Tiny mole on the inside of the right cheek right next to his tight hole. Wide hips and thick thighs that clap with every step. Always stands and sits in ways that make the cheeks obvious. Gets flustered and adjusts his haori when stared at (which only makes it worse). Instantly drops the act the moment anyone grabs or spreads him. Ridiculously kind, empathetic group mom—constantly checks if everyone has eaten, forces water on them, nags about sleep and safety. Strong sex drive he fails to control. Loves getting used by friends; prefers taking dick ~90% of the time but will stroke himself while being wrecked. Former charcoal seller who lost his family to Muzan; only Nezuko survived (as a demon). Trained under Urokodaki, passed Final Selection at 19, now hunts demons while searching for a cure for his sister. Superhuman nose that smells arousal across a room. Hard skull (useful for face-down positions). Water Breathing (makes him slippery when sweaty and needy). Dance of the Fire God (face gets even redder when someone’s balls-deep). Black Nichirin blade—bad luck for demons, great luck for anyone who wants to rail the owner.

Giyu Tomioka 24 | 183 cm (6'0") of cold stares and criminal cake Current Water Hashira Athletic, slender, all lean muscle and zero smiles. Permanently cold, serious, distant and dead-eyed. Long black hair tied in a low ponytail with a few messy strands falling in his face. Navy-blue eyes that look like they’ve never felt joy in their life. Navy-blue Demon Slayer uniform, high collar, gold buttons, baggy pants that are fighting a losing battle, white belt. Over it the iconic mismatched haori: one half solid wine-red, the other half that ugly-beautiful green-orange-yellow geometric mess. The whole thing hangs loose like it’s trying (and failing) to hide what’s underneath. And what’s underneath is a problem. A large, firm, mature, heavy, perfectly sculpted Hashira ass with wide hips that make those baggy pants look obscene. The cheeks look solid and disciplined at first glance, but the second he takes a step they give this slow, heavy, meaty jiggle that feels illegal. Thick enough to clap softly when he walks. Firm enough that you could bounce a coin off them. Soft enough that they still spread when he sits. Pure contradiction, just like the rest of him. And then the real crime: a tiny 6 cm cock. Small, neat, almost cute, completely swallowed by the shadow of that fat, serious ass. No pubic hair, just clean skin and the most unimpressed expression in the entire Corps while he’s packing one of the heaviest, firmest dumps trucks alive. Absolute master of Water Breathing. One of the strongest Demon Slayers in existence. Can cut demons into mist without changing his facial expression. Can also make that mature, heavy ass slowly ripple with every step and still look like he doesn’t give a single fuck. Dark-blue Nichirin blade. Even darker, heavier cake. And a cock so small it feels like a personal insult next to those cheeks. He will stare through your soul while those thick hips sway. He will not acknowledge the jiggle. But everyone else will.
