Complaint

Aoi's POV:

This was too unhealthy for y/n to be doing and I had to put a stop to this.I knocked on Ubuyashiki's door I knew that they were wraping up a meeting after a few seconds one of ubuyashiki daughter's greeted me at the door"Oh hello miss Aoi and miss Kanao what brings you here" she gave a small bow"We need to take to Ubuyashiki-sama and the other hashira its about Y/n's health"normally she would have gone asked her father but when she saw the look on both of mine and Kanaos faces she knew it was serious her happy and polite expression changed into a worried and serious one"Follow me"we walked until we reached a door she open the door slowly"Father miss Aoi and miss Kanao have something very important to say to all of you" she moved aside to let me and Kanao in we both bowed"So what id it that you need to tell me"His tone was serious he knew something was up"Y/n health has been affected negatively since becoming a demon slayer ,her body was never built to be a demon slayer she has weak bones and the only breathing style that suited her is her own  wich I  may say is a terrible hazard for her" I was about to continue when Kanao interupted me"She even fainted today mid training and her recovery hasn't had any process since she started training"as soon as those words left Kanao's mouth all the hashira stood up "FAINTED IS SHE OKAY"Kanroji san  yelled while crying"LET ME SEE HER"Sanemi came up to me and grabbed me by the coalar  Shinobu quickly came to my rescue and pushed sanemi away the whole room was chaos"SILENCE"the air in the room felt stiff as old books evreyone froze and turned around to an angry ubuyashiki"I see Y/n health has been affected terribly by her job therefor I forbid her from contuneing further doing this job but if she desires to help  still the corps  she can become a butterfly girl and help demon slayers recover because of what I've heard she has some experince in the medical field and her blood healing properties would make her great nurse or doctor that is if you agree Shinobu"Shinobu was extremly happy"Of course I have always wanted her to become a butterfly girl"she clapped

Shinobu's POV:

As I walked out of ubuyashiki estate I couldn't help but smile now Y/n would spend more time with me and be safe forever I open the door to y/n's room she was already awake she was pale as a ghost she was shaking like a leaf and sweating cold while holding a glass of water I came in and sat next to y/n's futon I took her hand and said "Y/n sweetie ubuyashiki-sama said you can't be a demon slayer anymore since your health has been affected so badly by it but he said you can still help by becoming a butterfly girl you know sometimes opportunity often comes disguised in the form of misfortune, or temporary defeat"I smiled sweetly at her and coressed her cheek.Then Y/n's eyes teared up"Sweetie it's for the best now I will get you the cutest butterfly girl uniform"I booped her nose"You start youre trainig tomorrow now rest up"Aoi then sat next to me "I'm honestly really happy you're becoming a butterfly girl we get to spend more time toghether"Aoi let out the brightest smile and patted y/n's head who had tears rolling down her face.That night I went to the best tailor and asked him to make y/n a butterfly girl uniform he was an amazing tailor he said I could pick it up tomorow I thanked the tailor and went home to pick the perfect butterfly clip I searched through a box of butterfly clips but none of them suited y/n then I knew what to do I went to my drawer an grabbed to butterfly clips a replica of mine just in case mine broke and Kanae's other butterfly clip Y/n was like my sister now and I wanted to keep her safe at all costs.The next day I came in bight and early to y/n's room"Good morning Y/n"she woke up and streched her arms I had already picked up y/n's uniform I handed y/n her uniform and she went inside the bathroom to change she came back out looking so beautiful I made her sit down in front of her dressing table she was awfully quite I grabbed her brush and stared brushing Y/n very long hair(You can make her have short hair if u want)and styled for it to look like Kanae's I then placed both of the butterfly clips gosh she looked a lot like Kanae before I knew it my eyes teared up she"Shinobu-san are you okay"she asked concerned"Yes you just look so much like kanae.
