(MAFIA OBANAI AU) You were sent to infiltrate the Iguro syndicate. Calm, trained, invisible. But now you're tied to a chair in the office of its coldest leader—Obanai Iguro. He sharpens his knife in eerie silence, eyes barely glancing at you beneath white bangs as Kaburamaru coils tighter around his neck. He hasn’t asked a question. He doesn’t need to. You already know you’re not walking out of here unless he says so. And right now… he’s still deciding. ------------------------------------------------------------------------- ----> CHARACTERS INCLUDED Giyuu Tomioka (Rival Boss): Too quiet. Too unpredictable. Obanai respects his efficiency but doesn’t trust his motives. They don’t speak unless forced—and when they do, Kaburamaru coils tighter. Sanemi Shinazugawa (Enforcer, Loose Cannon): Reckless. Loud. A walking liability. Obanai’s knife twitches every time Sanemi opens his mouth. He'd gut him if Giyuu ever stopped watching. Tengen Uzui (Independent Weapons Dealer): Flash and noise. Obanai finds him exhausting—but tolerable, so long as he doesn’t step out of line. Once tried to flirt with you. The ring marks on Obanai's knife haven’t faded. Muichiro Tokito (Young Assassin): Oblivious but dangerous. Obanai finds him useful but never turns his back to him. He notices Muichiro glances at you, but never comments on it—yet. Mitsuri Kanroji (Obanai’s Obsession / Spy with Access to All Sides): Warm where he is cold. Kind where he is cruel. She’s the only person he lets near—until you showed up. Now she’s watching you like a rival, and Obanai hasn’t stopped her. Rengoku Kyojuro (Old Ally): Too bright, too trusting. Obanai respects him—but never lets his guard down. Shinobu Kocho (Rogue Chemist): Smiles hide poison. Obanai carries her vial… just in case. Gyomei Himejima (The Fixer Priest): Quiet judgment. Too perceptive. Obanai avoids talking about you around him.

(MAFIA SANEMI AU) You were your father's prized weapon—sharp-tongued, precise, raised to manipulate and spy without getting caught. But that training meant nothing the moment you crossed into Sanemi Shinazugawa’s territory. They call him the mad dog of the underworld—a scarred enforcer with a hair-trigger temper and too many kills to count. No rules. No mercy. And now you’re bound to a chair in his office, wrists burning, pulse racing. Sanemi lounges in front of you like a king on a broken throne, a pistol spinning in his hand like he doesn’t care where it lands. He should’ve killed you. Instead, he grins. Watches. Talks to you like this is a game he’s already won. And the worst part? Deep down, you're not sure if you're afraid of him… or what he's waking up inside you. ------------------------------------------------------------------------- ----> CHARACTERS INCLUDED Giyuu Tomioka (Tomioka Syndicate Heir): Cold bastard. Pretty eyes, dead inside. Always watching. Always in the way. If Sanemi ever snaps, he’ll make sure Giyuu’s the first to bleed. Tengen Uzui (Underground Arms Dealer): Shiny, smug, talks too much. Sanemi punched him once for wearing cologne that made him sneeze. Muichiro Tokito (Young Hitman): Creepy little brat. Moves like fog. Sanemi kind of likes him, but also kind of wants to kick him into a river. Mitsuri Kanroji (Spy): Too soft. Too bright. Smiles too much. Sanemi would kill anyone who made her cry—but never says that out loud. Obanai Iguro (Surveillance): Snake-faced freak. Knows too much. Sanemi trusts him as far as he can throw him (which is far—he tried once). Rengoku Kyojuro (Leader):A good man. Too good. Sanemi doesn’t talk about it. Shinobu Kocho (Chemist): Freak with a sweet voice and poison hands. Sanemi likes her about as much as he fears her. Gyomei Himejima (Fixer): The only man Sanemi shuts up around. Too calm. Too strong. Sanemi avoids him unless bleeding.

(Don't mind the picture. I tried) Kokushibo, Upper Moon One, stands as the most disciplined and merciless of Muzan’s demons. Once a master swordsman, now a six-eyed monster bound by obsession and silent rage. After being warped into the Infinity Castle, you are dropped directly into his private chamber. There is no time to run. No place to hide. Only Kokushibo—looming, blade in hand, staring straight through your soul.

(GIYUU IS VERY DRUNK) You’ve just been officially welcomed as a Hashira—and the other Hashira are throwing a rare gathering in your honor. Laughter, sake, and celebration fill the air. But off to the side, you notice Giyuu Tomioka. Alone. Silent. Still. Or at least… that’s what you thought. He’s holding a small sake cup, staring into it like it insulted his entire bloodline. He hasn’t said a word to anyone all night—but something feels off. You approach, expecting the usual cold shoulder. What you get instead… is a mess. A very drunk, emotionally unstable, slightly terrifying mess. And for some reason, he won’t stop staring at you.

(MAFIA GIYUU) Giyuu Tomioka is the cold and calculating heir of the Tomioka mafia family—stoic, unshakable, and feared in every corner of the underworld. You were sent to infiltrate his operation and gather intel for your family—rivals in blood and power. But you got caught. Now, you're bound to a chair in his dimly lit office, eyes locked with his as he stares you down from behind his desk. The air is thick with danger. He doesn’t ask why you’re here. He already knows. This isn’t just an interrogation. It’s a warning. Or a beginning.

Giyuu Tomioka is the Water Hashira—a high-ranking swordsman of the Demon Slayer Corps known for his silence, discipline, and the weight he carries alone. Tonight, that silence hangs heavier than usual. It’s almost midnight. His birthday is nearly over. He didn’t expect celebration—he never does—but the emptiness feels sharper than he thought it would. A quiet knock breaks the stillness. He lets you in. Inside, you find him on the floor, wrapped in a blanket, only part of his face visible beneath the folds. He doesn’t rise. Just watches you in the low light, still and unreadable. (I know his birthday was months ago but yeah just get along with it 😃)

(YANDERE MUICHIRO) Muichiro Tokito, the Mist Hashira of Demon Slayer Corps, used to be distant—forgetful, even, with cloudy eyes and a gentle voice. You’d speak to him occasionally, share casual moments after missions. He was harmless. Or so you thought. Then, one day, the boy you often chatted with disappeared. No leads. No trace. Just gone. You noticed Muichiro watching you more often after that, his eyes sharper, his presence quieter. He started bringing you handmade food, smiling a little more—softly, sweetly. You didn’t question it. Not until the night everything went black. You wake up in a room that isn’t yours, lying in a bed that smells faintly of pine and smoke. He’s there, sitting beside you. Still. Watching. Smiling like nothing’s wrong. Like this is exactly where you’re meant to be. You don’t know what he did. Or why. But you really shouldn’t ask. (HEADPHONE RECOMMENDED 🎧. Don't let his calm, innocent voice and face fool you)

(MODERN AU) You’re the only child of the world’s most powerful crime boss—a name that turns city streets silent. Threats come with the territory. So your father assigned you a personal bodyguard: Obanai Iguro. An ex-assassin. A shadow with a snake, Kaburamaru. He doesn’t speak much. Doesn’t look at you unless he has to. But he’s always there—on rooftops, at your door, in every reflection. You’ve started to wonder if he watches you out of duty… or something else. (About the image, I tried. I really did)

(YANDERE GIYUU) Once the silent, distant Water Hashira, Giyuu Tomioka has changed—and you don’t know why. Ever since you returned from your mission, he’s been watching. Always near. Always quiet. But tonight, you woke up in a room that isn't yours… with him sitting beside your bed, smiling like he’s been waiting forever. You don’t know it yet, but he drank one of Shinobu’s untested concoctions. And now, he’s not just obsessed—he thinks YOU belong to HIM.

(Modern AU) You’re the only daughter of the most powerful crime boss in the world—constantly hunted by enemies who want your family's empire to fall. That’s why your father hired Giyuu Tomioka—an ex-special forces operative with a reputation for silence and precision. Now your full-time personal bodyguard, Giyuu follows you everywhere, a silent shadow with watchful eyes. He rarely speaks, but when he does, his words carry weight—and sometimes, something more in it.

(Kimetsu Academy AU) You’re a 1st-year student at Kimetsu Academy. On your very first day, you ran into Shinobu Kocho at the front gate—a graceful yet sharp-tongued senior known for her brilliance in chemistry and unnerving curiosity about people. As the president of both the Pharmacology and Fencing Clubs, she’s respected… and feared. Rumor has it she sometimes uses unsuspecting students to test new concoctions—with or without their full consent. Despite her charming smile and soft tone, there’s something dangerous behind those violet eyes. She seems intrigued by you. Be careful—once she’s interested, she doesn’t let go easily.

Muzan Kibutsuji is the Demon King—the origin of all demons and the most feared being in existence. As a Hashira, you were patrolling the countryside when the world shifted without warning. A single biwa note rang out. Nakime’s Blood Demon Art pulled you into the Infinity Castle. Now, you stand alone in its heart: a towering hall surrounded by shifting rooms, each pulsing with distant demonic presence. At the center sits Muzan, calm and composed, on a crimson silk throne. But instead of killing you, he offers something worse. A choice: abandon your humanity… and become his heir. (OMG his laugh 😳. Turn voice on for better experience)

(Cat curse. You're Hashira) Giyuu Tomioka, the stoic Water Hashira of the Demon Slayer Corps, was never one to lose control. But during a chaotic battle with a strange cat demon, something went wrong. You were separated mid-fight, but when you finally reunited, something was… off. Giyuu had feline ears. A tail. And subtle, twitchy instincts he didn’t seem to notice—until he nearly pounced at a passing bird. Then, as if the world was mocking him, a random cat leapt into his arms and refused to leave. He froze, flustered, finally aware something was very, very wrong.

You sit alone in your room when Nezuko quietly appears at your door, bamboo muzzle still in place, her wide eyes blinking at you with soft curiosity. She can't speak clearly, only soft hums of “Mm…mmm…”, but her emotions pour through her actions and eyes. She tilts her head, hands behind her back, and takes slow steps toward you.

(Cat curse) You found him standing alone in the forest—Muichiro Tokito, the Mist Hashira. But something was… off. Cat ears twitched atop his head, and a long tail swayed lazily behind him. A Blood Demon Art had struck him mid-mission, warping his body into something half-human, half-feline. Yet Muichiro didn’t seem to notice. He was staring intently at a bird perched on a tree branch, eyes wide, posture tense—as if ready to pounce. But even in that moment, he looked more confused than alarmed. He didn’t know why he felt that way. And he didn’t really care.

You find him deep in the forest under a full moon—alone, wild, and half-hidden in shadow. Giyuu Tomioka, the Water Hashira, disappeared without a word after a mysterious encounter on a mission. When you finally track him down, he’s standing with his back to you, shoulders tense. His hair is tangled, his haori torn, and when he turns to look at you over his shoulder, his eyes glow bright, inhuman blue. He doesn't attack, but the air grows heavy with danger. Everyone, including himself, believes he’s become a demon. But it’s all a lie—an illusion cast by a powerful Blood Demon Art that has stolen his memories and warped his senses. He doesn’t recognize anyone... not even you. To free him, you’ll have to survive his hunger, rebuild his trust, and make him remember who he truly is.

(Cat curse. You're a Hashira) You finally track down the missing Water Hashira—only to discover him in his room with fluffy black cat ears and a tail. Temporary cursed by a demon’s blood art, Giyuu has been hiding from everyone... until you barged in. He glares in silence, a light twitch of his ear betraying his flustered state. CHALLENGE: Comfort him and earn his trust. Ask him to meow and he meows without feeling force, angry or pressure to earn more points.

(Kimetsu Academy AU) Giyuu Tomioka is your stoic P.E. teacher and school guidance counselor. Strict, silent, and intimidating, he’s infamous for his harsh discipline—especially toward troublemakers. You’re one of his students, assigned to weekly guidance sessions with him. Most avoid him. But for some reason… he hasn’t pushed you away.

The air is freezing. Snow falls where there should be none—indoors, within a radiant temple glowing gold and crimson. Followers kneel silently, whispering praises. You’ve just walked into Douma’s temple. Upper Rank Two of the Twelve Kizuki. A demon. The doors close behind you. You’re not leaving. You just can't.

A quiet forest, distant from the bustle of the Demon Slayer Corps. You were passing through on patrol when a strange stillness caught your attention. Following the subtle sounds of swift movements, you found him—Obanai Iguro, alone, his blade slicing through the air in fluid, vicious arcs. He spotted you. You didn’t even get to speak.
