The Assassination Classroom is real?! (Various x reader)

Class-E

3rd POV-

As {y/n} slept on Karasuma laps, Koro-sensei went out and got her some clothes, since a towel was all that {y/n} was wearing. Being back in only a minute he was able to get an outfit that suited {y/n} taste.

"Karasuma, give {y/n} this, I got a class to teach." And with that he bid them goodbye.

A few hours has passed, Karasuma decided to wake {y/n} up, shaking {y/n} shoulders, groaning she opened her eyes, "5 more minutes mom" she sits up and rubs her eyes, looking around. "Oh right I'm not with them.." she looks down sadly"

"Hey kiddo don't feel like that, I know it's hard but remember if you kill this thing you get-"

"Yea yea I know 10 billion yen" she yawns while cutting him off.

"How'd you- never mind that, these are what you need to kill him, I'll give you extra because as you might know I talked to the ministry of defense about our little um interaction and they agreed." He handed her the green rubber knife and 2 hand guns with 3 packs of bb pellets.

{Y/n} grabbed the items and started to mess around with it, getting a feel of how to maneuver with them.

"Great! But one problem, I don't know how to speak Japanese?" She shrugs her shoulders in a matter-of-fact way

"We got that covered, the class and I got these electronic ear pieces that automatically translates what you say in English to Japanese and Vice versa." He handed her piece and put it on

"Cool! Thanks, now why about um..my clothes?" She points down

"The octopus provided what you need in here." He hands her a bag that had a doodle of a small octopus on it.

"Heh so he still does that huh?" She takes the bag and goes behind a little exit that's big enough so that she can change. Once she changed she walked out and put the guns on a strap around her leg and the knife in a case around her waist, she slightly blushing.

"What's the matter?" He ask d confused
"That Octo-perv got my measurements correct with my undergarments!" Her fist clenches in disgust.

He clears his throat and gives a small chuckle.
"Well we will be landing soon, get ready to be part of Kunugigaoka Junior High School."

She nods her head in understanding, I guess this is it, I can't believe I'll be going to that rich brat school. I'm going to be smarter than the class since I'm a high schooler back at home I was supposed to graduate but I'll deal with that later. Here I come Class-E.

Back in class E-

The students wait patiently for there teacher to arrive.

"This is new, Koro-sensei has never been late?" Blue hair boy said out loud
"Yeah he's right" Green hair girl looks outside to see if she can spot their teacher.

Just then a gust of wind came in the class as the door opens, a few people let out a surprise yelp.

"Welp we got our answer" the red head said

"Ne Koro-sensei why were you late?" The blue hair boy spoke again.

"Nufuhuhu well class as you might not know we have a new student, she'll be here any minute in the mean time please put these on" He gave every student the ear-translate
