Quick Strategies [Assassination classroom - Nagisa x Fem!Reader x Karma]

-Chapter One-

The classroom's aura was filled with tension. Everyone had there heads down with a scared like expression. It was quiet as well. You could here someone gulp it was so silent.

They waited in the most calm state they could, a few not as anxious as others. It was worrying how such a classroom with Junior High students were so tense. Soon, a loud rumble was heard outside, shaking the building slightly, making one of them look out the window.

They started sweating in anticipation. Slithering and squishy sounds were heard outside of the classroom. It came closer and closer. Soon, the door opened. It came inside and stood behind the class podium, setting down an Roll Book.

"Alright class, let's get started. Student on duty, on your word." It said. It at least stood at 9 feet or higher. It had a bulbous head with a large grin and small beady eyes. Two tentacles with off looking fingers had to of been presumably his arms. It also seemed to wear a black academic dress, a small squarish black academic cap with a yellow tassel and a large black tie with a yellow crescent-shaped moon on it.

A student had nodded and called back. "Right! Ready!" Suddenly, everyone had gotten out of there seats and took out weapons, which happened to be guns and aimed at the octopus like creature. They held pistols and assault rifles. It was quiet for a moment.

"Aim!"

It went silent again. Suddenly, the trigger word was said.

"Fire!"

Gunfire was heard from the students' firearms. As soon as fire was open, It started moving at such an inhuman speed, dodging the pink BB's.

"Oh my! Well, while you tire yourselves out, let me go over attendance!" It said in a cheery tone. And so he started Roll Call.

"Isogai?" He called over the gunfire. "Here." He called, which had been barely audible. "What was that?! I can't hear you over the all of the gunfire!!" "H-HERE!"

"Okajima!"

"Here!"

"Okuda?"

"Here!"

"Kataoka?"

"Here!"

"Kayano?"

"Here!"

"Kanzaki?"

"Here!"

"Splendid! All present and accounted for! NO TARDIES! CONGRATULATIONS!" It's face turned a bright orange.

"Damn... He's fast..." Someone mumbled. "The whole class opened fire and didn't even get a single scratch..." Isogai added.

"No luck today either, aye? That's really too bad." It commented. It soon began lecturing the class. "Excuse me sir, but how were you able to dodge all of that?!" An orange haired boy blurted out. "Yeah how did you manage to dodge all of that? The whole class did fire after all. Unless you just stood there and took the blow like a champ?" A dark blue haired male added, examining the a BB that had been of the floor.

It only sighed. It went on about how those BB's were harmless to humans but very affective to it. It gave an example by shooting it's own tentacle off. The whole class gasped in surprise. "But it'll just regenerate after a second of course." It pointed out after it's tentacle grew back.

It went on another lecture telling them how they should start thinking outside the box like true assassins. It told them that they could no longer use weapons inside the classroom as well. It then spoke in a cocky and grim tone as it went on, "I do hope you can kill be— before graduation that is..." It's face had green stripes, it's grin grew wider and it's  small eyes turned into a glare.
