Y/N was born into one of the Lambda facilities as part of a project called hybrid. Due to unseen issues when she was being transported to another facility, wild demons attacked the transportation. She was able to make it out alive but not knowing anything about the outside world put her at a disadvantage until she was found by two demons who appeared to not eat humans. She/Her pronouns the reader will be 12-13 when the escapees reach the bunker. this is mainly a ray x reader tho it will contain some other characters x reader. and I will be changing how old the kids are when they get shipped out, so instead of 6, it now will be 7. This book will follow the manga, mainly. I have not proofread any of this since I plan to come back later on and edit all my chapters but till then enjoy the odd (or a lot) of mistakes
