Tanjiro learns more about the Flame Hashira on the Journey, and his feelings of admiration grow into something more.... meanwhile Rengoku focuses more on their mission, But soon, Tanjiro's survival becomes more important to Rengoku than the Mission, and soon, something goes on between them, something that changes their relationship forever.
(this may include just a little 18+ and above aka sex. I'll have a warning at the top of the chapter if you wish to skip it, and also this takes place before Mugen Train! Hopefully, this isn't to confusing for you)
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.
