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. ( love in the air) -> you will read in the story who it will be. (Manga Spoilers⚠️) I do not own Demon Slayer; much of it is fictional. Start: 21/09/25 End: 17/10/25 Reminder: This is my first story written here in a long time. I hope you all like it. :)

Akemi Saionji was born to be the perfect porcelain doll: beautiful, silent, and convenient. Her world was confined within the high walls of a wealthy estate and governed by the rigid rules of etiquette. But within her chest, a spark always smoldered, needing only a gust of wind to erupt into a wildfire. A forbidden escapade into the night city and an encounter with the fiery Hashira, Kyojuro Rengoku, change everything. At thirteen, she escapes her golden cage, trading silks for a Slayer's uniform and hairpins for a blade. She must endure a year of solitude and despair in the wild forests before reuniting with her savior to become his Tsuguko. There, she will forge her own Breath of the Phoenix-a dance of death and rebirth. But is the refined aristocrat ready for the harsh sting of reality? And what happens when fate throws her together not with a noble prince, but with a wild, uncouth beast in a boar mask who turns her understanding of the world (and her patience) upside down? //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//.

Her name is Yukiko Tsukikage, but within the Demon Slayer Corps, she is known only as the Shadow Hashira. With hair the color of moon ashes and cold violet eyes, she is a living contradiction: a phantom of light waging war in the darkness. Her blade, which absorbs light, moves with impeccable precision, and her Breath of Shadow - a unique and deadly art-is unparalleled. To all, she is the perfect blade, honed by tragedy, devoid of emotion and flaw. But that is a lie. "The Flaw in the Blade" is the story of the last of her line, who fights not so much with the monsters outside, but with the legacy and feelings inside. Can she accept the part of herself she swore to destroy, or will her desperate pursuit of perfection lead her to self-destruction? And what if this hateful flaw in her soul is not a weakness, but the only thing that can still save her? //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.

In a world where humanity is fighting an eternal battle with demons, legends have a special value. One of them is about the Ryuga clan, whose descendants have been using Dragon's Breath for centuries. But the true power of this technique was lost 400 years ago, along with the last female warrior. And so, after many years, Nami is born - the first and only girl capable of reviving the greatness of her kind. At the age of 14, she becomes a Pillar of the Dragon, wielding a blade that changes color and a body marked with dragon scales. But even such a strong warrior will face difficulties when her paths cross with Tanjiro, a man who believes in a demon. //I do not own the world of Kimetsu No Yaiba, the rightful owner is Koyoharu Gotouge.

The first time he met her, it felt like the universe crashed into him. The second time, it was fleeting - just long enough to learn the sound of her voice. The third time, he pulled her out of the darkness... but the timing wasn't right. And the fourth time, he never let go. •••••••• Each and every time, his soul had recognized her before his mind did. She was gentle where he burned fierce, soft where he blazed. She was a quiet soul who never learned how to be loud, and he was a flame that never knew fire could also burn tenderly. •••••••• When Kyojuro Rengoku first met Koharu Ito, it felt like destiny announcing itself - not in thunder, but in silence. She was gentle where he was fierce, patient where he was driven. In a world ravaged by demons and duty, their paths should never have crossed more than once. Yet every meeting felt inevitable, as if some part of their souls had been waiting for the other all along. Now on AO3 (MoriNoHime)

As the world burns around them, their bond becomes both a weapon and a promise - that even in ruin, humanity endures. Now on AO3 (MoriNoHime)
