(A Demon Slayer Fanfiction - Very Slow Updates)
⚠️ Warning: Major manga spoilers ahead! ⚠️
How would you feel if you suddenly woke up with incredible powers and the gift of immortality? Would you call it a blessing? A miracle?
For a girl named Chiyo, immortality is nothing but a curse-a suffocating burden. She's forced to watch the people she loves wither and die while she continues to exist... endlessly.
Born in the year 600 of the Asuka era, Chiyo once lived a normal life-until it was ripped away. Her family was brutally murdered by two men connected to her father's debts. As if that weren't enough, Chiyo was kidnapped and tortured by the same men for three long years. When they finally believed she had died, they discarded her body in a mysterious river.
But death never came.
Instead, Chiyo awoke in a strange realm, greeted by a mysterious woman named Daichi... and everything changed. Her body healed. Her powers awakened. And her fate was rewritten.
But was it salvation-or something far worse?
Follow Chiyo's harrowing journey as she crosses paths with Demon Slayers, faces ancient demons, and carries the weight of centuries-seeking meaning in an eternal life she never wanted.
Note:
This is not a My Hero Academia x Demon Slayer crossover-just a standalone Demon Slayer fanfiction with its own original plotline. This story contains heavy manga spoilers and does not follow the anime storyline. I'm creating this story based on my own ideas and interpretations.
I'm also not following every backstory from the original KNY characters, as I don't know all of them in full-so please be kind and understanding.
✧ If it's not your thing, that's okay. Please don't read if you find it confusing or weird. ✧

Y/n was born into the Kurogane family, a distinguished bloodline of swordsmiths who specialized in forging Nichirin blades. From a young age, she showed not only talent for metallurgy but also a natural sensitivity to rhythm and flow-traits that made her movements almost dance-like, even with a practice sword. Her family believed she would continue the proud tradition of crafting blades, yet Y/n felt her fate belonged on the battlefield rather than the forge.

A Feather in the Storm (KNYxOC)
This is the story of a girl born in the mountains and raised by the wind, whose path leads from the icy solitude of vengeance to the searing warmth of comradeship and self-sacrifice. Ayaka Yamadori's life began in an idyll-a small house in the mountains, among a family of herbalists who taught her the language of plants and silence. But this world was shattered when she was just five years old. A Demon, obsessed with finding the mythical "Moon Root," broke into their home and murdered her parents. Ayaka herself survived by hiding in the cellar, listening as her world died. The horror left one silvery-white streak in her dark hair. The next morning, orphaned and desolate, she was found by a retired Demon Slayer, the stern recluse Saitō-san. For the next ten years, her home was a cold cave, and her family was her silent mentor. Saitō turned her life into continuous training, forging a deadly weapon from her grief and will. She grew up believing a simple truth: the world is divided into hunters and prey, and emotions are an unforgivable luxury that leads to death. At fifteen, after passing her master's final test, she descended the mountain to become a full-fledged Demon Slayer. //I do not own the world of Kimetsu No Yaiba, the rightful owner is Koyoharu Gotouge. This is fanfic, and the only characters I made are the ones introduced in the "OC" chapter//.Complete

Savior • Giyu Tomioka
At the tender age of 29, (Y/N) Rengoku found herself grappling with a reality she never envisioned. The tragic demise of her beloved husband aboard the Mugen Train, plunged her into a profound and shattering sorrow. The very fire that had once kindled her heart and animated her spirit had been cruelly extinguished, leaving her in a state of heart-wrenching defeat. Faced with the daunting task of carrying on for the sake of their kids, Hinoko and Kijuro Rengoku, (Y/N) found herself ensnared by the suffocating grip of despair. The weight of grief threatened to consume her, overshadowing the light that once illuminated her existence. In this bleak landscape, she yearned for salvation, a lifeline to pull her from the depths of her desolation. Even while hesitant, Giyu Tomioka felt an unexplainable pull toward (Y/N)'s plight. Though unprepared for the enormity of the challenge, Giyu felt an inexplicable determination to be the one to mend (Y/N)'s shattered spirit. He wished to shoulder the responsibility of her healing, aspiring to be the beacon of hope she so desperately needed. A story of Heratbreak, Acceptance, a little bit of Thrill, and definitely a lot of Romance. This is the story of how Giyu became her Saviour. A Giyu Tomioka × Reader Fanfiction.Complete

Y/N is an old-money European, that is until her parents decided to send her to a school in the United States in order for her to get a grasp of how life is without the luxury of Europe. In this story Y/N is a new student at Kimetsu Academy public school, what new challenges will she face? ♤♧♡♢ Hello everyone! This is my second fic but the first one is currently unfinished, so this one might not be the best considering that I started this in 8th grade and have not been on Wattpad for a long time. I'm an American upper middle class man so European or rich kid habits might not be totally accurate but I've done some research. A reoccurring thing that happens in most of my books is the overuse of the number four, see I have OCD and four is kind of my lucky number so if there is a quantity it will most likely be because of me not because of a hidden meaning behind the story or anything. I currently have Tiktok but I'm logged out. If anyone wants to be mutuals just message me, I'm always down to make new friends. 🗣️Y/N is upper class european so imagine her with a really snobby accent🗣️ ♤♧♡♢ Characters used: Tanjiro Nezuko Inosukee Zenitsu Kanao Aoi Genya Muichiro Yuichiro Shinobu Uzui Mitsuri Kyojuro Obanai Giyuu Kanae Sanemi Gyomei Yoriichi Murata Sabito Makomo Suma Makio Hinatsuru Hotaru Kanamori Kaigaku Ume (Daki) Gyutaro Nakime Hakuji (Akaza) Douma Michikatsu (Kokoshibo) Muzan Lady Tamayo Yushiro

// Honestly, I finished the manga and I'm trying to remember things as I go so I'm sorry peeps. \\ Rengoku has a past that you are fairly aware of since you grew up together. Kinda. After you both began to grow to try and achieve a future desired. You unfortunately faced the worst event in your lifetime. Rengoku had already moved elsewhere and during the couple days he's not been in the neighborhood anymore. The worst had happened. Striving to become a demon slayer, you became the enemy without choice. Miserably living your couple of days as a demon. It wasn't until a Hashira found you eventually. When brought to fight a foe that you were under prepared for, you find a familiar face in them. Stuck between wanting to die without another word or saying something. You let it all out regardless if your superior limited your every move. Now what would an old friend do in such a situation now that you guys are way off from a chance of redeeming any bond? The wheel of fate tries to find balance in between a on-going war. A demon with a demon slayer, nonetheless a Hashira at that; this violates code on both sides that were either written or just common sense. When attempting to work it out, you find each other to have a hard time even making it possible. Making the situation worse the longer you bond after lost time. Will your interactions contribute to Rengoku's life greatly and will be so that in your case? Cudos to: Koyoharu Gotouge and Art that I've found on Google for the chapters. *I won't be going back to this 😭 this story can honestly go whichever way for y'all.*Complete

The Last Trace: Child of Two Souls (KNYxOC)
Kirine Kage was born with a gift that became her curse. Her eyes are the color of silvery ice, and her body is sculpted for absolute silence. She is a child of a clan that has guarded the greatest secret for centuries: the location where the legendary Blue Spider Lily blooms. From childhood, Kirine learned not only the art of the hunt but also how to listen to her mother's silent lullaby-a map that reveals the path to this sacred flower. Her companion, the loyal wolf Gin, is her second soul, her second shadow. But when Kyōzo, the Fourth Upper Rank Demon, finds her village, this world of silence crumbles. Kirine's parents perish, and the secret they so fiercely protected falls onto her young shoulders. Now, Kirine is the last trace of her clan, a hunter whose only weapon is the Breath of the Phantom Predator and her faithful wolf. She steps into a world full of noise, pain, and betrayal to fight not only the demons but also the ghosts of her past. Her path is a road to the heart of the war, where she faces encounters with the legendary Pillars, brutal battles against the Upper Ranks, and finally, the ultimate hunt for the demon who destroyed her world. This is a story of strength born from silence, of loyalty forged in blood, and of a girl who must become the most lethal predator to protect her world. //I do not own the world of Kimetsu No Yaiba, the rightful owner is Koyoharu Gotouge.
