Demon Slayer
Demon slayer x FEM!reader Raised by an aging samurai in the quiet snows of the north, Y/N's only dream is to see the world beyond her village and wield her sword for something greater. When she begins writing letters to the famous Flame Hashira - never expecting a reply - her words become her secret solace. But years later, a response arrives from someone claiming to be Rengoku himself... though his letters sound far too warm, too young, too alive to belong to an old master. Two souls connected by ink and parchment. One mistaken identity. And a love destined to burn brighter than the flames that brought them together. [DISCLAIMER] I do not own any of the characters except (Y/n) and any original characters. All the other characters and Demon Slayer belong to Koyoharu Gotouge.

  • Tragic Love.

Some bonds were never meant to survive the sun. She didn't ask to be turned. Didn't want the dreams of others stitched into her bones. But now Kyahan lives in the silence between nightmares, half a demon, half a ghost, feeding on broken sleep and holding herself together with threadbare hope. Then he finds her. Rengoku Kyojuro. A man of fire, of honour, of impossible warmth. He should have killed her. Instead, he looked at her like she was still someone. Now they're spiralling into something neither can name, tethered by a power that shouldn't exist and feelings that cannot survive what's coming. Because dreams can't touch flame without burning. And love can't save what was born to be hunted. But maybe... just maybe, it can change how the story ends. A slow-burn psychological tragedy. A romance that dances on the edge of death. And a final act you won't forget.
