Our string ( Nagisa x reader)

kid you

Lunch time rolled around so you decided to sit in a tree near the field while eating your bento but something tasted different it tasted sweeter you wanted more so you ate the whole thing when you were done you jumped down the tree and ran to the classroom to put your bento away but everything started getting bigger you look at your hands and see little baby hands that kinda reminded you of B/n your clothes shrunk with you  and you yelled

You: Okuda!!!!!!!

You voice sounded squeaky Okuda Karma Nagisa and Meg run in the room

Meg: don't tell me that's

You: Okuda can you explain why I'm a little kid again

Karma: wow who knew you grew up so adorable Y/n

You puff your cheeks as Nagisa lifts you up and sits you on the desk you cross your arms  and stare at him with a spark in your eyes

Nagisa: your about the same size as B/n

He poked your nose you grab his finger as you grow smaller your teeth are now gone as you tease on Nagisa's finger

Meg: Okuda you have to change her back

Okuda: it should wear off by tomorrow morning for now where just gonna have to wait it out

If you picked  blue

Mega groans Nakamura comes in and widens her eyes

Nakamura: who snagged a baby in hear

Okuda: that's Y/n

Nakamura: what happened?

Okuda: earlier I dropped a vile into Y/n's bento I tried to get it but Y/n already took it

You laugh making everyone aww at your cuteness Nakamura walks over to you you look at her and cry making her back up Nagisa picked you up and cradled you making your crying fade and your eyes turn blue you may be a baby but your still not in a good mood with Nakamura

Meg: how come you and Y/n won't talk to eachother anymore?

Nakamura: I when we were in the forest I was mad that she picked to save Korosensie when she said it herself he's the target and the target always dies I shouldn't have said it I feel like a total jerk now I knew she said it when she had her tentacles taking control of her so I shouldn't have used it against her

You reach out to her with your baby hands she picks you up and hugs you you pull her hair making her wine you giggle at her

You: [ I feel better now ]

You put your finger in your mouth you grow bigger at least B/n's size again

Nakamura: whoa

Meg: Okuda what was that

Okuda: I think it's because she heard something mature I don't know

Karma: hmm her eyes are blue looks like she's taking after people

Nakamura: her eyes look more like Nagisa's

Okuda: it must be something else in it 

If you picked red

Toka and Nakamura came in they squealed at the sight if you and started taking pictures

Nakamura: what happend to Y/n

Toka: she's a thousand times cuter than ever now

Your ears twitch as the snapping sound runs through your ears Nakamura picks you up

Karma: I should start taking pictures and  send this  out who knows how Y/n will react

Nakamura put you down on the ground and you stomp over to Karma and hit his leg

You: you big meanie don't do that Kama

He laughed his ass off as he recorded you your voice was so priceless he couldn't stand it you puff your cheeks again Nagisa picked you up and poked your nose again you giggle as your eyes turn blue

Okuda: wow her eyes are blue

Nakamura: she kinda looks like your kid Nagisa

Nagisa: it's weird whoever she touches she takes after them

Original story

You pull at Nagisa hair making his pigtail come out

You: Na-gi!

Nakamura: at least she's not forgetting us

Meg: yea but who's gonna watch her?

Nagisa set you on the floor and you ran out the classroom into Itona

Itona: what the

You grow taller and grab his hand

You: hey Itona

Nakamura followed you and facepalmed

Itona: what's with Y/n

Nagisa: she kinda got into Okuda's stuff

Itona: hmm she's taller than I would imagine a kid

Nakamura: I'm starting to wish you just go to your regular age

You playfully stick your tongue at her and run pass Itona then crash into Korosensie he picked  you up and examined you

Korosensie: now who are you

You: hi Korosensie can you put me down now

He put you down and his face was pretty confusing

Okuda: Korosensie don't flip out its just Y/n

Korosensie patted her head

Korosensie: it's fine but I suggest you do your experiments somewhere away from Y/n we don't want her turning into a fish now do we

Time skip

School ended and Nagisa had to sneak you past the main building and out of the campus you were now holding his hand while skipping next to him

You: hey Nagisa do you know ice cream has cream in it it doesn't taste creamy

Nagisa: I think it's because of what  it's made out of that's why it has cream in it

You: cool!

Lady: oh look at that girl and her daughter

Lady2: aw she has her eyes

Lady3: she looks awful young for a child

You: hey Nagi you think if I had cat claws would I still look cute?

Nagisa: probably your cute no matter how dangerous you are

You giggle and lean in Nagisa's arm as you walk home

B/n: hey Nagisa where's onii-chan?

You: I'm right here

B/ n: your not onii-chan she's has e/c eyes and she's taller

Nagisa: it's a little magic act Y/n will look like onii-chan tomorrow okay

B/ n: okay I can wait

You walk over to B/n and hug him be hugs back and you both wobble around then yawned

Nagisa: are you guys tired

B/ n fell asleep on you Nagisa picks him up and sets him on his bed you crawl in your  bed still in your clothes Nagisa layed down next to you with you sleeping in his chest he pecked your forehead before falling asleep
