    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. This is fanfic, and the only characters I made are the ones introduced in the "OC" chapter//.

    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//.

    Story Title: Whispers Of The Silken Veil Genre: Historical Dark Fantasy / Supernatural / Tragedy KNY × MALE OC Story Description: In the fading twilight of the Edo period, a nobleman named Seijuro Kurohana vanished from courtly life, lost to rumors and silence. Now, beneath the quiet glow of the moon, a ghost-like figure moves through remote villages, veiled in silk, wielding grace and death in equal measure. Once human, Seijuro is now a demon who defied Muzan Kibutsuji's control. Bound not by hunger, but by honor, he roams the night feeding only on beasts and the wicked, protecting the innocent in secret. His Blood Demon Art, Hagoromo no En-the Dance of the Silken Veil, renders him untouchable, ethereal, and deadly. But Seijuro's long existence is not without torment. Haunted by memories of his former life, hunted by demons and demon slayers alike, and drawn into a conflict he never wished to join, he must decide whether neutrality is a shield or a cage. As war brews in the shadows and ancient forces stir, the veil may fall, and with it, the last remnant of who he once was. Might have slow updates

    Kaya and Kaizu Miyasato, two normal half Canadian, half Japanese siblings find themselves transported to a world Kaizu knew little of, but Kaya knew quite well: Demon Slayer. However, there was a bigger problem than the mystery of how they'd ended up there; The two had been separated from each other with no way of knowing where the other was, or even if they were alive. Kaizu found himself in the company of Tanjiro and Nezuko, whom he at least knew a little about due to reading the first manga. Kaya ended up stuck with Obanai Iguro as his Tsuguko, under Shinobu's suggestion. Both siblings had one goal: find the other. They didn't particularly care for the demons, they just wanted the company of someone they knew from their lives beforehand. Will the duo be able to survive a world full of demons and find their way back to each other, or are they doomed to meet the same fate as so many others...
