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

Finally test day

After we've been studying for god knows how long, with all the little Koro-sensei holograms I feel like this will go well.

As I look around the classroom everyone seems so focused on working that I couldn't help but smile.

"Ne {y/n}-san why are you smiling?" Sensei asked with an American headband on.
"Just seeing everyone working so hard to make it to the top 50 as you said, it amazes me on how hard they work" I giggled and looked up at him
"Now it's my turn, I'm going to kick those snobby pricks so hard they won't see what's comin!!" I grinned as we both started working. 

After al the studying it was time to go home. I cleaned the board as everyone left.

"What's taking him so long!" I pout as I opened the door to the teachers room
"Ne onii-chan what's taking so lon-" I was cut off once I saw a specific someone.
"Asano?" The one and only principle. I hate him no doubt about it.
"Ahh look at we have here the American transfer student" he faked a smile and got up and walked to me "It's good to finally meet you" he stuck out his hand
I looked at it then at Karasuma, he gave me that 'deal with it' look so I shook his hand.
"Same here" I allowed myself to show a little disgust but quick changed it

God why does he have to be here?!

"Nufufu that's where you went-" Sensei walked in and stared
"Nice to meet you Koro-sensei" he smiled
"This is apparently the principle" "Which makes him our boss" Bitch-Sensei and Karasuma said

Just then Sensei started to massage his shoulders and give him sweets.

"I forgot he's a total suck up" I sighed
"I just came by to talk about Class-E, the reputation I mean, you know if the students manage to kill you, I need to keep their reputation just the way it is" he sits on the window ledge

"Tch bastard" I whispered

He knows exactly what we are doing, telling Sensei that the kids should still be at the bottom of the food chain...he only ever cares about his image.

I growled slightly as he talked.

"You know the worker ant principle? That's exactly how this is, there are those 5% of slackers while the 95% are hard workers and strive to not be like those 5%. I strive so that the students built in 'I don't want to be like Class-E' that's exactly how it should be I hope I make myself clear" he stood up and walked towards the door.

"Oh not to mention I got a complaint from a D class teacher that the foreigner and a guy threatened to kill them" he looked at me with amusing eyes. Kill?! I beg to differ..

"I'll take my leave, I won't stand in the way of your assassination attempts" he looks at me "And not to mention I don't think it's legal to allow a high schooler to take a junior high test" he grins

"H-How!?" I whispered in shocked. How the hell did he know that?! He'll do anything to make sure non of us gets to the top 50
"That is correct, however as of now since she came to Japan, she in known as a junior high student that goes to your school and nothing else." Karasuma took a step in front of me.

He glares at him then leaves. I slammed my hand on the wall

"That no good principle, I've always wanted to kick his ass when I had the chance" I gritted my teeth as Karasuma put a hand on my shoulder.
"Calm down we need you right now" he sighed
"Let's go home please?" I looked up at him
"Fine let's go"

And with that we said our good bye.

This isn't good for class E....he's underestimating them and they're letting him win...
