Our string ( Nagisa x reader)

Almost

You and Nagisa were at your house making a plan to assassinate Korosensie then Nagisa got an idea

Nagisa: how about you dress up like a unknown assassin and try to take him out by surprise

You: what in the world should I wear?

Nagisa: you have a reaper costume don't you?

You: ooh great idea!!

You rush to your closet and pull out a black leather vest with black tights and a black hood and black arm warmers

You: you should go to school you'll see me there just tell Korosensie I'm sick

Nagisa: ok see you later

He pecked your cheek and walked out you grab black boots that go up to your knees along with cherry lip gloss just to wear you also grab a black mask that covers your mouth you put it on and let your hair out so you would fell comfortable with the hood on then look at yourself in the mirror

You: I look awesome!!

You grab your bag along with your gun, knife and keys and place them in your bag as you walk out the door

Time skip

You stand in front of the door your hood covering your eyes with your mask on you knock on the door gently dropping you bag to the side with your gun hidden

Korosensie: come in!

You open the door and step in you could sense all eyes on you you look and see Nagisa at the front with Korosensie he was blushing that you found adorable

You: are you Korosensie?

Your voice was low and sweet so he wouldn't recognize your upbeat and cheery voice

Korosensie: why yes I am! who are you?

You: that information is classified

You look at Nagisa and stand in front of him

You: are you also Shiota Nagisa?

he nods you smile behind your mask and take it off and pull one of his pigtails and kiss him you hear gasp and snaps from the whole class you pull away looking at him in a daze

You: at lunch meet me behind the school don't be late

You place your mask back on your face as you walk out the door saying

You: I hope I get close to killing you Korosensie

You grab your bag and walk out into the forest

Nakamura: woah looks like Y/n is gonna have to fight for her man

Kayano: I wish she wasn't sick!!

Korosensie grabbed a napkin and cleaned off Nagisa's lips

Nagisa: what are you doing?

Korosensie: she left lip gloss all over you Y/n will be furious

Nagisa had to hold back a chuckle knowing it was you the entire time

Another time skip

Nagisa walked out the classroom to the back of the school to find you standing there waiting for him

You: finally Nagisa-kun I was starting to get bored

You walk up to him and pull him away from the windows

You: so what's next?

Nagisa: you could come in again challenging him to a fight

You: with his mach 20 speed? I'm gonna look like a joke

Nagisa: they tell him don't use it

You: ok but hey don't I look awesome in this outfit!?

Nagisa: you looked adorable but that kiss left lip gloss all over me

You: oops?

He gave you a kiss on the nose since you still had your mask on

Nagisa: I almost thought you were a different person by the was you talked

You: well I can't blow my cover now can I?

Nagisa: you should get ready for the fight

You: did you not see what I did to him last time?

Nagisa: true

He takes off your mask and plants a kiss on your lips you suck his bottom lip making him moan a little

You: you should go lunch will be over soon

You place the mask back on and give him a quick hug he hugs back the walks off

Last time skip

You walk out of the forest to where the class was for gym taking them all from the lesson onto you

Kayano: guys look it's the girl that lip marked Nagisa

Hinata: twice

Nakamura: girl Y/n is gonna get you

You try not to laugh as you face Korosensie

You: Korosensie how about a quick fight

Korosensie's grey faced turned back to yellow

Korosensie: ooh great some fun

You: ah ah ah you are not allowed to use your mach speed ability I want to see what your capable of

Green stripes appear on his face you smirk behind your mask

Korosensie: I am strong and clever even with out mach speed

You: I never said you weren't

You whip out your guns shooting off a tentacle shocking him

You: oops didn't mean to pull the trigger

You shot off another tentacle as he tries to attack but you dodge and shoot off another then you pull out a knife and throw it at him slicing off another

You: don't worry I have 430 more I would love for you to enjoy

You kept throwing knifes at him no matter where he goes as he was attacking with tentacles but you kept jumping a giggling and you throw a knife at his tentacles as they go near you all his tentacles were gone you grabbed your gun again ready to shoot

You: Korosensie at least you were strong enough to hit me

A scar was going down your left cheek as you were ready to pull the trigger until you feel a shot in your arm you drop your gun and look to see Shiro

Shiro: now Y/n that's 1000 yen your stealing from me

Nakamura: Y/ n!!?

Kayano: that was you!!?

You pull out the needle and Korosensie regenerates pulling you off the ground

You: what did you shoot in me!!!?

Shiro: you'll be fine

Everyone rushed to your aid as your mask and hood fall off Itona grabs the needle and hiss eye widen

Itona: this is the-

You didn't hear the rest because you blacked out
