Rainbow Eyes - (Douma x Reader)

Who would have guessed that such an exceptional fighter such as Y/N would have attracted the THE Muzan Kibutsuji's attention at such a young age but here she is a century later and trained by the best of the best demons. But where dose a Human raised by the things they fight and kill stand with the Demon slayer Corps?

(Art isn't mine and also I don't own demon slayer or it's character to be clear) much love - Lucette 💜
