Assassination Classroom/Ansatsu Kyoushitsu Various x Reader one-shots

Jealous!Isogai x Shy!Reader {Difficult but Easy}

Requested by @BlackKnightRadiant

Was planning on publishing a BL one-shot first, but it was too hard for me to write...so I am gonna write this first! Not that I don't want to write it, it's just that I don't really know how to write that kind of stuff...myabe I just have to switch the gender?

Honestly, I think this one-shot will be the typical the prince-saves-the-princess-and-they-live-happily-ever-after plot but the prince is really jealous and the princess can't even talk without stumbling but she is actually a bloodthirsty monster inside...

===================================

Your POV

Peeking around the tree, you quickly hide again, clasping your hands together in front of your chest, taking in a deep breath before peeking around again and then hide again.

"I can do this." You mumble to yourself, praying a bit before hugging your bag, keeping your head down as you walk quickly over to the building.

Reaching the doorway, you take a step forwards before going back again, repeating a few more times before gathering up your courage and walk straight to the classroom door, stopping again.

"It's just a few people, I won't die, nothing will happen, I just have to open the door and walk in and introduce myself to 26 people..." you mumble, getting even more nervous and start jumping slightly when you hear the teacher asks you to go in.

Carefully sliding open the door, you keep your head down buried in the bag, walking in with shaky legs.

"O-Ohayo, I-I am (L/N) (Y-Y/N)." You stammer, trying to say it louder but your voice just came out like a mouse squeaking.

"Eh, (L/N)-san, right?" Hearing a kind voice, you look up to find a yellow wiggly creature with pill-sized eyes and a large smile.

Shaking even more, tears appear in your eyes, and you fall to the ground, hiccuping and crying slightly.

"Koro-sensei, you scared the new student. Maybe you should consider being a monster in a haunted house instead." A mischevious voice rings from the back of the classroom.

You look over to find a red-haired male, and sob even louder. "Karma, don't say anything else. I think you are making her even more scared. (Y/N), calm down a bit, okay?"

Hearing a familiar voice, you look over to find a smiling boy kneeling in front of you.

"Y-Yuu-kun...why is there a yellow wiggly monster in this class?" You ask, hiccuping as you calm down slowly.

Isogai has been your "prince-charming" since he talked to you in your first year, and when you realised that your "prince" is going to be in the E Class, you slowly lowered your grades until you got in, but now, seeing the yellow creature, you are hesitating.

"Well, how do I say this? He is our teacher, Koro-sensei, and we are going to kill him." He explains, scratching the back of his neck.

"Kill...? With this?" You ask again, taking out a gun from your bag which Karasuma-sensei has given to you yesterday.

He nods, and you point it towards Koro-sensei, your hand still shaking as you stammer out, "C-Can I try t-this out? I-I won't hurt you, I just w-want to try this."

When you see him nod, bloodlust suddenly appears in your eyes, your mouth curling up into a bloodthirsty smirk. "Then, die." You said, and before anyone can come out from their shock, the bullets coming out from the gun hit Koro-sensei's tentacles, and he barely escaped the one being aimed at his brain.
