A young girl who grew up in Japan is used as a lab subject by who she could only assume were her parents. she ran out of her home after finding out the terrible truth about them. She loses her friend and learns about these things called demon slayers. She meets this strange man, I recognize him. who is he? Hi everyone this is my first Fanfiction on here :) I'm excited to share with you guys the story of my OC. You are free to use my OC as a self-insert although this is still my OC so she will still have her own personality and features. I give all credits to any art that I use to the original artists I do not own any of it. There will most likely be some plot holes I haven't read the manga so some things at the start will be off lmao. Anyways, I hope you enjoy my story.
