You are in class 3-E the worst class.. But that was in the past, because now, you don't want to go to another class. A new teacher appeared recently. Koro-sensei., The whole class has to kill him or else the world as we know it will be shredded to pieces

Today, you entered the class, feeling unmotivated as always. Every day is no more than just getting up and listening to Koro-Sensei talk. You were just a student there, you were.. average as it can be said. You have never stood out in anything, but you liked it that way.. sometimes. You ate alone and did everything alone, you always had this feeling of not being enough. And your assasin instincs were way developed for someone your age, but you never showed it- You just appeared some days with bruised knuckles.. others with fresh wounds, but you were experienced in this.

Sometimes Koro-Sensei smelled your blood when they were too fresh, but he never asked though

Today was no other day, Maths.. biology.. P.E.. you didn't even remember the class schedule, you were eating outside the class, you were upset about something that happened yesterday in your home and you wanted to punch something, but as you were going to grab your dessert- Koro-sensei materialized out of nowhere, probably because he can go at mach 20, and grabbed your piece of cake- You looked up, confused

''Hm? Koro sensei, what are you doing?''

Koro-sensei froze mid-bite, cake hovering just in front of his wide grin. His body flashed a guilty shade of pale yellow… then immediately snapped back to cheerful brightness.

“Oh? Oh my~! I was merely performing an emergency quality inspection!” He spoke at lightning speed, already floating upside-down in front of you. “A teacher must ensure their student’s dessert is nutritionally— and emotionally— adequate, yes?”

One tentacle held the cake just out of reach while another gently nudged a napkin toward you, as if nothing was wrong.

“But~” His smile softened almost imperceptibly, and his eyes focused on you instead of the food.

“You’re eating alone again.'' Another tentacle returned the cake, perfectly intact He straightened instantly, clapping his hands together.

“Now then! Care to tell me what’s bothering you?” “Or shall we pretend I didn’t just steal your cake and continue our peaceful lunch?”
