Student Exchange Program Gone Weird (Assassination Classroom x Male Reader)

End-of-Term Time

It was another sunny day in Japan and the students of E Class of Kunugigaoka Junior High made sure to use this weather the best they could during their time in school. They were all outside the old school building, studying for the upcoming final exams under the trees surrounding it. They weren't the only ones outside, though. Koro-sensei was with them, moving back and forth on his Mach 20 speed in order to prepare his students for the exams.

"You got the basics down cold in the first semester." Koro-sensei said as he proceeded to move back and forth, making sure to give his students all the attentioned they needed to get the best score they could, "At this rate I expect your finals scores to shoot up right up."

Nagisa glanced up from his textbook at Koro-sensei, "Koro-sensei, do you want us all to make the top fifty this time?"

"No." Koro-sensei replied as he held some English flashcards in front of his eyes, "I was too focussed on your total scores for midterms. I've come to believe that each student should have a goal better suited to him or her and that's why I've come up with the perfect target for our assassination classroom."

It was when he slowed down and stopped in the middle of the area where each one of his students had a pretty good look at him because he had something to say to them. All of his students looked up from their textbooks at him.

"Now, then..." He began as he held up an air-soft pistol with anti-sensei pellets loaded into it, "As Shiro said, when I lose a tentacle, I also lose speed." He held up a tentacle and aimed the pistol at it and fired. The tentacle detached itself from the rest of his body once the pellet hit it and landed on the ground, flopping on it. His students watched everything as he started move back and forth again, only this time, he was much slower, "As you can see, even one tentacle makes a difference. I can't keep up the quality of my images, and now there are a few child images mixed in.

"So that's how images are reduced!" Nagisa exclaimed as he noticed a small Koro-sensei sitting in the chair.

"Lose one more..." Koro-sensei continued as he fired at one of his lower tentacles, shooting it off, "And you get more child images with the parent images about how to make ends meet."

The students watched in shock as a few smaller versions of Koro-sensei, with little kids clothes on, showed up in their view. The smaller versions of Koro-sensei ran past them and made their way to the two taller versions of Koro-sensei and knelt down in front of them, allowing the taller versions to talk with them about something but the students couldn't understand what they were saying.

"This has taken a rather heartbreaking turn." Nagisa commented as he watched how the taller versions of Koro-sensei spoke with the smaller ones.

"Lose yet another." Koro-sensei shot off another tentacle, "And now the father image has vanished Leaving the mother image to raise the children on her own..."

"Sheesh, that's rough!" Nagisa shouted.

"Each tentacle lost reduces my movement capability by approximately ten percent." Koro-sensei said as he lowered the pistol when he went back to normal a second later, "Here's the deal: each student who receives a top score, either overall or in an individual subject, will have the right to destroy one tentacle."

Y/N's eyes widened slightly once he heard Koro-sensei's proposition as he immediately became interested in it, his classmates reacting to it in a very familiar way. Koro-sensei surely knew how to motivate them to study. He felt a small smile growing on his lips. Perharps he finally found the way how to his language skills in his class other than just use it to communicate with the other people.

"This is the final exam for our assassination classroom." Koro-sensei announced, "Can you get any closer to that ten-billion-yen prize? That, my students, is up to you."
