Reincarnated as Rui in Demon Slayer

Now reborn as Rui, our pansexual female protagonist is now a boy. Packed with the inevitable future of turning into a demon, dying to the main protagonist helper giyuu, and Muzan being supper clingy, what shall she do? What hope is there at all? (There will be a harem, bxb/yaoi/boy love, yandere themes, lack of me caring to edit, if you don't like any of the things I mentioned, it's better to leave right now as your reading this, and not when you are in the middle of reading this. Also I will be referring to Rui as she/her in her point of view as our protagonist still thinks of themself as a female, just in a male's body, I will be referring to Rui as he/him in anyone else's point of view. If you don't like that may the door be close by with the power of the force.)
