Fem! Demon Y/N meets some Demon Slayers

(I made this in 2021 but published it in 2022 please forgive my stupid younger self that did not know how to write in any way possible) (2024 update, uhm this sucks and is very cringe so if you wanna read this brace yourself)

You meet Tanjiro after the last they left the butterfly mansion in the last episode (no manga or anime spoilers though). You were injured after a fight with (M/N) (mother's name) she hated you after "you killed your father", Tanjiro, Zenitsu & Inosuke help you after you collapsed in a small town. They take you to the butterfly mansion where you are healed (yes I know the (Y/N) is a demon but let's say that you didn't develop good healing capabilities). But then you lie down on one of the beds in the far back corner and you fall asleep...
