DEMON Slayer SSBBW
The Butterfly in the Larder
The wedding preparations in the Swordsmith Village were unlike anything the secret valley had ever seen. While the forge fires usually roared for the creation of killing edges, they now burned to roast whole hogs and simmer vats of sweet, thick glazes. Mitsuri Kanroji, the bride-to-be, sat nestled atop a mountain of silk cushions in the center of the Chief’s private pavilion. She was a vision of immense, soft splendor, her fingers idly tracing the floral patterns on a plate that had, until moments ago, been piled high with honeyed dumplings.
"You look truly divine, Mitsuri-dono," Chief Doragon’eiji murmured, standing beside her. He no longer looked at her with the shock of their first meeting. Instead, his gaze was one of possessive adoration. He reached out to stroke the back of her hand, which was now so dimpled and soft that his fingers seemed to disappear into the warmth of her skin.
Mitsuri giggled, the sound vibrating through her heavy chest and causing the layers of her scarlet robe to shimmer. "Everyone is so kind. I used to worry so much about being 'too much' for a husband. But here... I feel like I'm just getting started!"
"You are exactly as you should be," Gasuto said, appearing from behind a screen with a fresh tray of steaming buns. "But a bride should not be lonely in her final days of preparation. It is the custom of our village to ensure the bride has a companion of her own status to share in the... festivities."
Mitsuri tilted her head, her triple-braided hair resting heavily against the soft curve of her shoulders. "A companion? But I’m the only girl from the Corps here. Unless... did Shinobu-chan send a message?"
Gasuto’s mask seemed to curve into a deeper, more secret smile. "Better than a message, Lady Mitsuri. When the Insect Hashira came looking for you a few weeks ago, we told her you were deep in the mountains under spiritual seclusion. We invited her to wait. She was quite insistent on finding you, but eventually, the mountain air and our hospitality won her over as well."
Mitsuri’s heart gave a little skip of joy, sending a ripple across her rounded form. "Shinobu-chan is here? Oh, I’ve missed her so much! Is she coming to see me? We can have tea together!"
"She is already in the adjacent chamber," Gasuto replied, gesturing toward the heavy sliding doors at the far end of the pavilion. "She has been undergoing the same 'restoration' as you. She was quite frail when she arrived, you know. All that running and those harsh poisons she works with... it wasn't healthy for a young woman's constitution."
With a nod from the Chief, the attendants pulled back the doors. Mitsuri leaned forward as much as her newfound weight would allow, her eyes wide with anticipation.
"Shinobu-chan!" Mitsuri squealed.
The woman who sat in the next room was almost unrecognizable, yet the purple-edged butterfly haori draped over her shoulders was unmistakable. Shinobu Kocho, the famously petite and slender Insect Hashira, was no longer small. She was seated in a wide, reinforced wooden chair, her frame having expanded to a scale that rivaled Mitsuri’s own.
Her once-sharp, delicate face was now framed by soft, pale cheeks that gave her a cherubic appearance. Her purple eyes, usually flickering with a hidden, sharp anger, looked glazed and heavy-lidded. Her uniform had been replaced by a loose, lilac-colored kimono that struggled to contain the vast, soft curves of her torso. Her arms, which used to be thin enough to snap like twigs, were now thick and pillowy, resting atop a stomach that spilled over her lap in a magnificent, heavy slope.
"Mitsuri...?" Shinobu’s voice was slower than usual, lacking its typical clinical edge. It was breathy and sweet, like honey dripping from a spoon. "Is that you? I... I came to find you. But then the tea... the tea was so good. And the cakes..."
Mitsuri clapped her hands together, the flesh of her palms meeting with a soft, muffled sound. "Shinobu-chan! You look wonderful! You look so healthy and soft! Doesn't she look beautiful, Doragon’eiji-sama?"
The Chief nodded, though his eyes remained mostly on Mitsuri. "The Insect Hashira has proven to be an excellent guest. She has a very refined palate. She particularly enjoyed the lotus-root paste we prepared with the special additives."
Shinobu tried to adjust herself in her chair, but the effort seemed to exhaust her. Her heavy thighs rubbed together with a soft friction of silk, and she let out a long, contented sigh. "I feel so... quiet inside, Mitsuri. The anger... it’s just gone. It’s hard to be angry when you’re this full. I think I finally understand what you meant about the joy of eating."
Mitsuri’s heart swelled with love. She scooted herself across the floor, her body moving with a slow, rhythmic sway until she reached the threshold of Shinobu’s room. The two women, once the fastest and most agile warriors of the Demon Slayer Corps, now sat like two great, soft monuments to the village’s twisted generosity.
"It’s wonderful, isn't it?" Mitsuri reached out and took Shinobu’s hand. Shinobu’s fingers were plump and warm, lacking the callouses of a swordsman. "We don't have to fight anymore. We don't have to worry about Upper Moons or tragedy. We can just stay here and be happy. Gasuto-san says the village needs us. They want us to be the mothers of a new generation of smiths!"
Shinobu’s gaze drifted to a plate of glazed chestnuts sitting on a small table beside her. "Mothers... yes. I suppose a body like this is meant for that. It feels so heavy, Mitsuri. Every time I think about standing up, I just... I’d rather have another bite of something sweet."
Gasuto stepped between them, her presence like a shadow over a feast. "And you shall have it. We have prepared a special lunch for the two of you. A celebration of your reunion. After that, we must begin fitting the wedding garments. We’ve had to order extra silk from the capital; the local looms simply couldn't keep up with your... blossoming."
Attendants flooded the room, carrying trays that dwarfed the ones Mitsuri had seen before. There were deep bowls of fatty pork belly braised in soy and sugar, platters of fried tofu stuffed with minced shrimp, and massive wooden tubs of rice glistening with duck fat. The air became thick with the scent of salt, sugar, and the faint, spicy undertone of the village’s secret additive.
"Eat, Shinobu-chan!" Mitsuri urged, picking up a pair of chopsticks. "You have to catch up to me! We're going to be the most beautiful women the mountains have ever seen."
Shinobu didn't need much convincing. She reached for a piece of the pork, her movements slow and deliberate. As she ate, the glazed look in her eyes deepened. The additives were working quickly on her smaller frame, softening the sharp corners of her mind and layering her body with the "prosperity" the village demanded.
"It’s so... peaceful," Shinobu whispered between bites. "I forgot what it was like to not be tired. I’m still heavy, but it’s a different kind of tired. A happy one."
"That is the feeling of belonging," Gasuto said, her voice dripping with artificial warmth. "The Corps used you for your speed and your venom. We value you for your essence. You are the treasures of the Swordsmith Village now. Hidden away, just like the blades we forge."
As the afternoon wore on, the two Hashira lost themselves in the rhythm of the meal. The sounds of the village—the distant clanging of hammers on steel—felt like a dream from another life. Here, in the heart of the Chief’s estate, the only reality was the taste of the food and the growing, heavy warmth in their limbs.
Mitsuri watched Shinobu, feeling a sense of pride. Her friend looked so much more relaxed. The sharp, tense lines around Shinobu’s mouth had vanished, buried under the soft fullness of her cheeks. Even the butterfly ornament in her hair seemed to sit differently, perched atop a head that was now tilted back in a daze of caloric bliss.
"You know," Mitsuri said, her voice muffled as she chewed on a sweet bean cake, "I used to be so afraid that no one would love me because of how much I ate. But the Chief... he looks at me like I’m a masterpiece."
"He does," Shinobu agreed, her voice trailing off as she reached for a bowl of thick, sweet porridge. "And the villagers... they look at me like I’m precious. Not like a weapon. Just... precious."
The tragedy of their situation was entirely lost on them. The two most powerful women in the organization dedicated to protecting humanity were being systematically fed into a state of total dependency. Their muscles, once honed for the lightning-fast movements of Insect and Love Breathing, were being replaced by layers of soft, sedentary weight. Their minds, once sharp enough to outsmart centuries-old demons, were being clouded by a constant, drug-induced euphoria.
By the time the sun began to set, casting long, orange shadows across the tatami mats, neither woman could have stood up even if a demon had crashed through the roof. Mitsuri was leaning back against a pile of bolsters, her breath coming in short, happy puffs as her stomach rose and fell in a slow, rhythmic swell. Beside her, Shinobu had slumped slightly in her chair, her head resting against the high back, a small, sleepy smile on her face.
Gasuto entered the room quietly, followed by the Chief. They stood at the doorway, looking at the two women.
"They are perfect," the Chief whispered. "The Insect Hashira... she will make a fine wife for my brother. A lineage of poison-masters and smiths. Our village will be invincible."
"And the Love Hashira?" Gasuto asked.
"She is mine," Doragon’eiji replied, his gaze fixed on Mitsuri’s radiant, sleeping face. "She is the heart of the mountain now. We will keep them here, fed and happy, until the world outside forgets they ever existed."
Gasuto bowed. "The wedding is in three days, my Lord. By then, they will be even more... substantial. They won't even be able to cross the threshold without assistance. They are truly bound to us now."
In her sleep, Mitsuri dreamed of a world made of sakura mochi and endless summer afternoons. She dreamed of Shinobu laughing, not a sharp, pained laugh, but a deep, belly-shaking sound that echoed through a house filled with children. She felt a hand on her cheek—the Chief’s hand—and she leaned into it, a soft moan of contentment escaping her lips.
The butterfly had been caught in the web, and the flower had been plucked and planted in a golden pot. The Swordsmith Village had claimed its prizes, and as the mountain mists rolled in to hide the valley from the rest of the world, the Love Hashira and the Insect Hashira drifted further away from the path of the warrior, sinking deeper into the soft, stifling embrace of their new lives.
Outside, a single Kasugai crow circled the village, cawing in confusion. It could smell the scent of its masters, but the village was silent, save for the crackle of the cooking fires and the low, haunting melody of a flute. The crow waited, but no messages came. No orders were barked. There was only the heavy, sweet scent of the feast, and the knowledge that, for Mitsuri and Shinobu, the war was finally, irrevocably over.
