Muzankibutsiji Stories

Everyone believed the story had already been written. Y/N refused to accept it. After dying in her own world, Y/N is reincarnated into the world of Demon Slayer by the gods with memories of everything yet to come. Determined to save everyone she once cried for, she rewrites battles that should have ended in tragedy, earns the trust of the Hashira, and slowly becomes one of the Corps' strongest swordswoman. But changing fate comes with consequences. A legendary swordsman forgotten by history becomes her first companion. A demon no one can ever discover becomes part of her family. The Hashira begin questioning the impossible coincidences surrounding her. And somewhere in the shadows... Muzan Kibutsuji realizes someone already knows every move he has yet to make. The future is changing. The gods are watching. And this time... Even destiny has no idea how the story will end. This is a isekai/ reincarnation story!

So basically y/n finds Muzan and Douma in his room after trying read a smut fic of Muzan. Will y/n be able to get them back? Will y/n succumb to Muzan and f\ck him? I don't know. Read to find out I guess. (Also y/n has a pet spider,bc I said so<3) I lowkey suck with grammar so feel free to correct me-
