The demon king Muzan Kibutsuji has planned the ultimate downfall of the Demon Slayer corps. However, when the flame hashira, Kyojuro Rengoku, suddenly retires from his post, and his student Minami Ryuu is promoted as the Nature hashira to take his place, an unforeseen series of events occurs that could see Muzan's plans fall to ruin.

[Started: 07/23/2025] [Ended: ???] ━━━ 美しく, 最愛 ⤷ Koyuki was only thirteen years old when she met Hakuji, whom she called her beloved.She's loved Hakuji ever since the day her father took him into their home. One day, Hakuji proposed to Koyuki over the doorstop while the fireworks exploded in the sky. Koyuki loved Hakuji so dearly, as did he. Her and Hakuji were about to get married but one day, Koyuki and her father went to fetch water from a well, not knowing that it had been poisoned. It didn't take long for them to feel the effects of the poison, passing away within ten minutes of drinking it. Hakuji returned home and people in the village told him about their deaths, and he rushed home. The first thing he did was cradle Koyuki's pale and cold body in despair. Koyuki woke up, and found herself as a young child. She realized she had reincarnated with the same looks and name as her first life and decided to take the new life she had to find Hakuji, her love. She heard about the demon slayer corps and thought that it might be easier to find Hakuji if she did. One day, after a mission with the flame hashira Rengoku Kyojuro on the Mugen train, another demon had suddenly appeared, making a loud sound as it hit the ground. When the dust cleared, she widened her eyes in recognition as she realized who this demon was. ❝𝐇𝐚𝐤𝐮𝐣𝐢? 𝐈𝐬 𝐭𝐡𝐚𝐭 𝐲𝐨𝐮?...❞ [Read to find out more!]

Come look into the lives of the Hashira in a world where Demons rule. What will come of their lives if they never were slayers? Based in the same AU as 'Who's In Control', an AU in which the slayers lost long ago and Muzan has conquered the world.

(Old title : What If?) --"You...You don't know anything of the sins I've committed since you- since you..."-- What if Koyuki was reincarnated as a demon slayer? Will this change in fate save lives, heed way to new encounters, and lead to a brilliant victory for the demon slayers? Or will it usher in a downward spiral that will ultimately bring about the deaths of our favorite heroes? 《Who knew a simple girl held the power to change fate?》 ! SPOILERS ! for the manga. (Characters do not belong to me except Mikaru Chizuki, my oc. Cover artwork belongs to @odr_lol) Weekly updates, hopefully. :')

Muzan and his Uppermoons were turned to stone by Tamayo. Now they awaken to the Reiwa Era. The first being Douma as the scent of familiar blood wakes him from his stone slumber. - The Disney Gargoyle's inspired story that no one asked for but what I needed. A Douma X Kotoha set in the Reiwa era story

Akaza, uppermoon three, reunites with his deceased fiance after she unknowingly becomes a demon to live with her fiance once more. Tragedy stands in their way as they both don't remember their human lives and encounter each other, not recognizing their long lost lover.

The moment everything changed was the moment Doma felt something within him. His chest was not hollow - his heart was not still... not anymore. Something in him stirred and he felt a small twinge of his lungs, filling him with foreign warmth. Suddenly, the world was vibrant, and at the center of it was her. She was called Kotoha, a young woman with dark hair, deep beautiful eyes, and a truly lilting voice that seemed to soothe the heavens in its softness. Doma was transfixed. The baby in her arms suddenly didn't seem so annoying in its cooing and her smile didn't seem fake as he assumed most were. The day everything changed was the day Doma smiled for the first time. WARNING: Contains death, gore, reference to SA, trauma, blood, foul language, and angst. There will be more specific TW on chapters that handle heavier topics but these are the main ones. WARNING: Also contains a reformed Doma, a redemption for Akaza (with some romance included), Inosuke gets a family, Kotoha gets to be happy, Daki and Gyutaro get to heal, Genya and Sanemi WILL communicate eventually, Uzui is vibin', Kanae gets to L I V E, Tamayo gets some motherly recovery, Kokushibo has an existential crisis, Nezuko will eventually get some character development, Muzan is TICKED, and life is good... mostly. Also, Kotoha adopts... everyone. Just... everyone. I don't own Demon Slayer (Kimetsu no Yaiba) or any of the art! Yes, I am aware most spellings spell Doma's name as Douma; no I'm not changing it no we're too far gone.
