Ayyeee Douma. He didn’t deserve the family he was born into. But good for me cause I can draw him all sad and stuff

Who fell first? Who fell harder?

Pairing: Kokushibo, Douma, Akaza, Muzan x gn!human!reader

Genre: Fluff

Note: Since the hashira version got so popular…

Muzan Kibutsuji // The Demon King

He fell first and fell harder.

Muzan does not choose his partners willy-nilly. He is supposed to become the peak of evolution, the greatest being there is and was and so far, his human partners were rather disappointing. They cried and had to be killed once they found out the truth of his inhumanity, so none of them were around for long.

That is when he found you. You were a regular, almost boring human being. Nothing special. Or at least, that is what Muzan thought at first when he met you as the new apprentice of the florist he consulted every now and then, your face having dirt smudges and fingers small cuts made by thorns, but still you gave him the kindest smile he had seen in a while. You captivated him, just like that.

After courting and convincing you to move in with him, the presumed very rich businessman, and finding out that he is actually much more horrible than a regular man, and yet you continued to surprise him by showing barely any negative reaction. Only ask of you was for him not to eat humans in front of you, of which he’ll oblige.

It was hard not to fall head over heels immediately. Muzan grew fond and protective of you, asking you to remain in the infinity castle instead of his regular home to have easier access to both your lips to kiss for recharging energy but also keeping an eye on you for safekeeping. He is smitten.

Kokushibo // Upper Moon One

He fell first, you fell harder.

He didn’t believe in soulmates, really.

Pairing: Douma x gn!follower!reader

Prompt: Soulmate AU

(Douma being a little more demon-ish in this one)

⋆⁺₊⋆ ☾⋆⁺₊⋆

Douma heard tales of the so called “Red String” that supposedly connected people by their souls, helping them find each other so they can life the rest of their lives united. Not even as a child did he believe there might a person that is connected to his soul. What soul? He doesn’t even have one.

Does he?

I got bored and did some traditional ink lol!

Douma x Reader - general headcanons

DEMON SLAYER MASTERLIST

❄︎ Douma is basically the embodiment of gluttony. Not just when it comes to devouring humans, but in how he wants to utterly consume every pretty, lively, warm thing he can get his hands on. And you? Of everything in the world, it’s you he wants most. He doesn’t even know if it’s love in the human sense - he probably wouldn’t know how to describe it even if you ever asked him to - but every time you smile at him, it sparks something strange in that hollow chest of his. He’ll cup your cheeks with those ice-cold hands and whisper with a grin, “Ah, little lotus! I feel weird inside! My stomach is all wobbly, but it’s not like when I got poisoned before… Does this… Is this what love feels like for humans?!”

❄︎ He calls you every saccharine pet name imaginable: my lotus blossom, little snowflake, pretty petal - sickly sweet, over the top, but always in that sing-song voice of his that makes it hard to tell if he’s mocking you or genuinely adoring your presence. He just loves watching how you react.

❄︎ Douma’s clingy in an almost childlike way. And he doesn’t do personal space. In fact, Douma doesn’t seem to understand the concept at all, and even if he does, he simply chooses to ignore it. That’s why the rainbow-eyed demon will drape himself across your lap, rest his chin on your shoulder when you’re focused on some task, poke your cheek with a claw just to see you flinch. 

❄︎ He loves gracing you, literally. Flowers braided into your hair, little ribbons placed to your shoulders, anything to make you look even more like a living doll. You’re his favorite ornament in the entire Infinity Castle.

❄︎ Douma willingly listens to you ramble about anything. You’ll start rambling about something random or meaningless, and he’ll just tilt his head left to right like a curious puppy, even giving you a nod or two, sometimes letting out soft “mhm” or “ahh, I see” sounds, all with that empty smile plastered on his face. It’s because he’s amused by how your voice changes as you speak. “Mhm, mhm… Say that again, snowflake. I love how your voice hits that word, hahaha!”

❄︎ He often presses you against the walls of the Infinity Castle - or even the walls of his own temple - on purpose while you’re just walking together, just to hear your heart skip a beat. He leans in close, nostrils flaring as if sniffing out your fear, cold breath ghosting over the shell of your ear. In that syrupy-sweet, sing-song voice, he coos, “Why are you shaking like that, little petal? What’s got you so scared? Ah, calm down, calm down, lotus! You know I’d never eat you, silly!” Of course, he does it purely for his own amusement, savoring the thrill of your fear and the tension that radiates from you.

❄︎ Douma’s kisses are overwhelming. One second he’s all smiles, the next he’s crushing his mouth against yours, stealing every bit of air until you’re trembling and pawing at his chest, begging for oxygen. Abruptly, he’ll pull back with that angelic smile gracing his lips, pretending innocence while his rainbow eyes gleam with pure lust. “Oh, dear, forgive me, I think I got carried away again! But you don’t mind, right?”

❄︎ Douma doesn’t get angry often, but when he does - it’s terrifying. Though he usually hides behind that sing-song politeness, there are moments when the mask cracks. His smile doesn’t fade, but it changes. It stretches too tight, his words drip honey that suddenly feels poisonous. If you question his ways, defy him or suggest leaving, that saccharine tone of his sharpens like glass. “After all I’ve given you, lotus, you’d really abandon me? How cruel of you! Lord Akaza is mean enough to me already, hmm? Even our Master scolds me sometimes! You don’t need to be rude too, little lotus… That’s not very nice. I don’t approve of it, you know.”

❄︎ One of Douma’s favorite activities (besides devouring females and then whining about the dirty floors or the wooden bridges over his precious lotus pond) is having you brush his hair. He’s always so meticulous about his appearance. When you comb through his platinum hair, occasionally rubbing his scalp while softly humming his favorite melody, the demon goes completely weak in the knees. He leans back with that playful grin, eyes sparkling as he whispers, “Ah, little lotus… Just like that, don’t stop. You have no idea how good it feels… Your hands… They make me feel oh, so good.” ❄︎ Then there’s Douma’s secret room. The only place in the Infinity Castle nobody else goes into, where he keeps his collection - skulls arranged like trophies, vases holding preserved female heads with hair still cascading down. He’s oddly proud to show you this place, leading you in with his usual cheerful tone, “Look, aren’t they breathtaking? I couldn’t possibly let such beauty go to waste!” The air in there is heavy with decay, suffocating, yet Douma treats it like a truly sacred chamber. Sometimes he’ll brush and braid the hair of one of the heads, humming some melodious tune. Douma often glances at you, rainbow-coloured eyes glinting too brightly. “Don’t you see, sweet lotus? They’re just like you! Lovely things deserve to be kept forever!” And that’s the thing - letting you see that room is Douma’s twisted version of trust. But it’s also a trap. Because once you’ve been in there, you can’t just walk away. You’re bound to him, whether you like it or not.
