(Has Been Adopted)yandere kny insane asylum x caretaker F reader

the start

yn looked down at her job application, it had gotten approved just moments after she had sent it in, at this point that place had been really desperate to get anyone.

while the place itself was not that bad, it was a very comfortable place with it's own indoor basketball court and indoor swimming pool, though that had only been reserved for the staff since someone had tried to drown themselfs in it.

but there was the people in it, they were full of dangerous criminals who have done unspeakable crime's only to have been found insane at the end, one of those people's were apparently her 4 sisters who have been doing awful things behind her back, which is why yn was so confused when the police suddenly came to her house and arrested her sisters.

that was the reason yn was going to work here as a caretaker in the first place, because this place didn't allow guests so yn just decided to work here so she could see them.

yn took out a picture in her pocket and smiled at it, the picture of her,kanae, shinobu, kanao, and aoi all sitting together in a butterfly field enjoying a nice picnic.

yn quickly put the picture back in her pocket, then entered the front door of the asylum.

almost immediately a person came to greet yn and led her to oyokata's office were he then greeted her too.

"hi it's nice to meet you i'm kagaya ubuyashiki but please feel free to call me oyokata, i'm so glad you agreed to work with us, as you know where a little short on staff"

"it's nice to meet you i'm yn kocho, i'm glad that you accepted me, as you know some of my sisters are patients here and i'm so glad that you let me work here, because I wouldn't be able to see them otherwise"

oyokata only smiled didn't say anything...

yn let out a deep breath as she exited oyokata's office, he had explained to her how things worked around here and what to do, he also told her to go meet all the patients here and that she could start with her sisters if she wanted too.

she had a stack papers in her hand explaining all of the people in here and what they did and why they were in here, though the one file yn didn't want to look at were here sisters, she didn't want to know what they did and what their insanity was.

she grabbed the key card that oyokata had given her and walked towards the door that all four of her sisters had been put in.

she used the keycard to open the door then made sure to put it in her pocket and zip it in it.

she saw that the room was covered in butterfly's that her sisters love so much, she noticed that the room looked somewhat empty but maybe that was because she didn't see any of them.

yn walked closer to the beds, 'did oyokata play tricks on me when he said my sisters would be in he-'

yn's thoughts were cut off when she was suddenly hug attacked from behind, she recognized these pair of arms, they were kanae's.

"ara~ara I was so happy when I heard you were taking this job, not only do we get to spend time with you but your just in arms reach" kanae said rubbing her head on yn's.

"Oh I'm happy to see you again too, though we might not be able to spend as much time as I would like with you it's better then nothing" yn told her.

it was then yn remembered that it was four people to a room when three other pairs of arms wrapped around her, that meant all four of her sisters were giving her bear hugs, strangely enough yn didn't remember them being the touchy.

"if you don't mind me asking but what exactly did you guys do, no one would tell m-" yn was cut off when shinobu put a finger on her lips.

"ara~ara, yn don't ask questions with answers you won't like"she said.

eventually yn had to squeeze out of the bear hug she was trapped in, "oyokata, said that I could stay with you guys for about thirty minuets before I go see the other patients, so is their anything you wanted to do?" yn asked them.

the four of them talked for a bit, deciding what they wanted to do with yn, "hey yn can we do your hair, I remember always doing and that was fun" aoi said, the others nodding in a agreement.

"ok, we can do that, do you have any equipment, I don't think they let you bring some-"

"we do, they let us bring anything we wanted" shinobu said, getting up an going to a drawer.

before yn had the chance to think about how it was weird they let them bring anything they wanted, kanao was starting to drag her to the one of the beds, they all forced her butt onto the bed and got to work.

first on of them pulled down the ponytail that yn had been wearing, yn's long and thick hair fell down, for whatever reason they never let yn cut her hair even when she practically begged them.

They all did a braid, meaning yn had four braids in her hair, they seemed to take this longer than it would take a normal person to, they spent every second relishing the feeling of yn's silky hair.

When they were finished yn was surprised when she suddenly felt a little snap above her head.

Yn reached up to feel it immediately, "what's this?" Yn asked.

"A little gift we made you, it would make us very happy if you wore it ever day" Shinobu told her.

"Oh really I'll make sure to wear it all the time then" yn said happily.

It was then yn noticed the time, how had thirty minutes passed already?

"Oh I'm sorry it appears I have to go now, I'll make sure to say goodbye to you when I leave" yn said before exiting the room.

Only once Shinobu,kanae, kanao, and Aoi were 100% sure yn was go did they take out a device.

Or in other words a tracking device, that was connected to the pin in yn's hair.

Ok end(I make to many yandere stories)
