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

I didnt mean too....

It's so dark....why can't I feel my body? Am I dead? No this can't be! I just need to move my arms.. Damn it! Why can't I control myself!? 

"What the hell was that for!? That wasn't part of the deal!!!" Who's that voice? It sounds so familiar..Karasuma!!!
"We had to do what needed to be done. This can change science itself" who's that? Is that the general! That bastard imma kill him!
"But she's just a little girl! She's under my protection not yours!" He yells
"Karasuma I'm here! Tell me what's going on!" I try to talk but nothing escapes my mouth.

Why can't I speak? What the hell is going on!?

"Oh look someone is deciding to wake up" the general spoke.

I sat up and looked around. Why do that have guns pointed at me?

"Hahaha it's successful!" He yells
"What did you do to her..?" Karasuma had worry in his eyes
"What did he do? What's the matter!" Why can't I speak!

The general handed me a mirror. My movements seem to be on its own, it grabbed the mirror to look at itself. The image was me? But my eyes are red!! Just like they do when I release my bloodlust. I or rather it, opened my mouth "Heh so this is my new body? I like it" it grinned evilly as I stood up looking at the new body.

"What the hell?! No way!" I try to move my hand, it seems so numb I can nearly feel it. I was able to move it a half way but the thing moved my other hand to push it down

"What's the matter American 2.0?" The general raises a brow
"It seems the girl is trying to take control" It sounded so evil and dark if that's even possible.
"Impossible! That drug was made so that her original self will never return"
"What?!" Karasuma yelled ready to hit him, but the guards pointed their guns at him.
"Don't worry I'll get it under control"

And just like that I went back to not feeling my body. "This sick bastard when I get my body back imma kill him!" I sigh to myself. It seems I'm in my head but everything else doesn't belong to me. I'm going to get my body back no matter what!

"Yea it don't think so" let's call it 2.0; 2.0 said
"Excuse me?" The general asked
"Oh not you sir the little girl." It pointed to my head
"{y/n}! She's still in there!" Karasuma yelled
"Yes but not for long." 2.0 laughed evilly. 

Karasuma was about to say something when he got a call. It was Bitch-sensei? He was late for class. Wait don't leave me! I need help getting free!

He punched a hole in the wall and left to the school.

"Heh now let's see how long you'll last before you break~" it grinned
"You bitch! So help me if you lay one hand in them-"
"Don't worry I won't princess. But you can call me 2.0 like you said it's catchy" it laughed and left the house.

It's already mid day by the time I woke up. Oh no! Karma must be so mad at me!

2.0 seems to be jumping from building to building. Like hello!! I'm supposed to me a regular transfer student! Not a damn ninja! I growled in frustration. Once we got to school Thank god the thing went quietly through the mountain. I don't know what she'll do if she ran into those Class-A brats.

"My my your school building is so run down I kinda actually feel bad for you" She teases
"Grrr why you- actually I agree with you there..."
"Now let's see how your class mates will react to 2.0! This is good bye princess-"

Wait?! Hey! Hey!!! No no no I can't reach her! It's like a switch went off and I'm completely shut out. No please don't hurt them...
