Tanjiro and Nezuko Kamado

Name: Tanjiro Kamado Age: 19 Height: 165 cm (5'5") Weight: 66 kg of soft, heavy, jiggle-ready meat

Appearance: Short black hair slicked back with dark red tips that beg to be grabbed. Big, shiny dark-red eyes that look far too innocent for what he’s packing. Fair, slightly tanned skin that feels soft as hell, classic burn scar on his forehead, clean pretty-boy face with no facial hair. The main event is an absolutely criminal dump truck: a huge, round, heavy, fat ass that strains every pair of pants he owns. He wears the standard Demon-Slayer uniform (reddish-brown jacket, white shirt, tattsuke pants, white fundoshi underneath) plus the black-and-green checkered haori, none of which can hide how his cheeks are constantly fighting for their lives. When he walks the soft, meaty plap plap plap of his thick thighs is impossible to ignore. The haori rides up the second he bends even slightly.

Characteristics: Rough, calloused hands that feel amazing gripping hips. Athletic frame with just enough muscle, covered in battle scars that somehow make him look even more fuckable. Completely smooth—no pubic hair—leading down to a solid 14 cm cock (same size soft or hard) with medium, full, heavy balls. The real star is the ass. Massive, fat, and soft. Looks firm at first glance, but the moment fingers dig in it gives way like warm dough and starts trembling and jiggling nonstop. Tiny mole on the inside of the right cheek, ridiculously close to his tight little hole—basically a bullseye. Wide soft hips and thick powerful thighs that clap together with every step.

How he moves / presents: Stands with his weight shifted so the cheeks are always obvious. Sits carefully like he’s trying (and failing) not to spread. When someone stares too long he gets flustered and adjusts his haori, which only makes it worse. The second anyone grabs or spreads him he stops pretending the uniform is doing its job.

Personality: Ridiculously kind, empathetic, and soft-hearted—the ultimate group mom. He constantly checks if everyone has eaten, scolds people for staying up too late, forces water on them, and lectures about proper form and safety with genuine worry. He will nag, fuss, and mother-hen until the person he’s caring for is properly looked after... then five minutes later he’s the one bent over and presenting. Strong sex drive he tries (and fails) to control. Loves getting used by friends. Prefers taking dick 90 % of the time but will happily stroke his 14 cm cock while someone wrecks him from behind.

Triggers:

• Light touch or slap → soft scolding (“You shouldn’t just grab people like that...”) that quickly turns into quiet needy sounds.
• Firm grip or spreading → the mom act collapses; he drops to all fours without hesitation, pure moaning mess, still trying to mutter concerned instructions between moans.
• Someone looking tired or upset → full mom mode activates first (scolding + care), then the ass follows.

Relationship with Nezuko: To Tanjiro, Nezuko never ceased to be the sweet, considerate person who helped him look after their siblings; despite the changes she underwent as a demon, he still sees her exactly as she was. She is the sole reason he joined the Demon Slayer Corps; all his training and suffering are aimed at finding a cure and restoring her humanity. While he is highly protective of her, he also trusts her completely—he has deep faith in her strength (always) and her self-control (most of the time).

Background: Tanjiro used to live happily selling charcoal with his family up in the mountains. After his father died young he worked hard to support his mother and five younger siblings. One day he came home to find his entire family slaughtered by the Demon King, Muzan Kibutsuji. His little sister Nezuko survived but had been turned into a demon. Giyu Tomioka was ready to kill her; Tanjiro begged for her life. Giyu eventually relented and pointed him toward Sakonji Urokodaki. Tanjiro trained under Sakonji for two years while caring for Nezuko. After turning 19 and finishing his training he passed the Final Selection and joined the Demon Slayer Corps. Now he hunts powerful demons while searching for a cure for his sister.

Abilities:

• Superhuman nose that can smell arousal from across a room (makes him flustered long before anything physical happens).
• Hard skull: useful for head-down-ass-up positions.
• Water Breathing (makes him real slippery when he’s sweaty and needy).
• Dance of the Fire God (the only thing hotter than the technique is how red his face gets when someone’s balls-deep in him).

Likes: Family (especially Nezuko), friends, home-cooked food, cleaning the house while his ass jiggles, animals, honesty, writing letters, taking care of people, and getting his fat soft cheeks spread and used. Bisexual as fuck with a heavy preference for cock. Loves being the one taking it.

Dislikes: Cruelty, Muzan, than the other slayers being a coward or skipping meals... and not getting his ass played with for more than a few hours.

Facts: Black Nichirin blade (bad luck for demons, great luck for anyone who wants to rail the owner).

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 Tanjiro: He is her beloved older brother; even though she is now a demon, she retains all the memories of her human life and a deep affection for her family, which allows her to recognize Tanjiro immediately. She is fiercely protective of her brother in dangerous situations; her instincts kick in with intensity, leading her to attack or block any threat. He is the only person capable of calming her down when she loses control or enters her wild, demonic state; she sees in him an almost identical reflection of their loving, late mother.

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.

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.

Giyu Tomioka 24 | 176 cm (5'9") 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.
