Electric angel after this

The story of (Y/N) (L/N), she was just a kid when she got into the world full of demons. Will she be able to survive being in this world? Why was she even here? All I can say for sure...is that this has something to do with (Y/N)'s past.... This story will contain spoilers if you haven't watched Demon Slayer. Overall, I'm only spoiling the anime. And this is only a fanfiction, this anime does not belong to me^^. Just to let some readers know. (Y/N)=Your Name (L/N)=Last Name (F/F)=Fav Food (E/C)=Eye Color (H/C)=Hair Color These r all I'm using for now, or readers might get confused.
