Mysterious Transferee (Assassination Classroom Reader-Insert)

'Fifteen, no, sixteen of them. Judging by their breathing, they're young, mostly in the mid-teens. Everyone who can still move actually made it here.' The man thought as he fires his gun at the back and hits something that sounds like a glass made material. Some of the students covered their ears as the rest grits their teeth.

"Just to let you know, this hall is completely soundproof. I'll have you all killed by a shot before anyone can come here to save you." He twirls his gun with his right index finger and continues. "You know you're not ready to kill anyone, right? Now, come out like good children and bow before the---" He was cut off by a bullet whizzing past him, barely missing his twirling gun.

He stops his actions as Rinka, the one who shot, was disappointed that she missed the gun that she was aiming for. 'Real gun? And from the sound of it... did they took our goons Model 60's? Junior high kids trained for assassination...' He gets a remote from his pant's pocket and turns on the lights from behind him.

"Finally! A job I can sink my teeth into!" He laughs madly afterwards as the students adjust to the sudden light. 'I can't see the stage with that backlight.' Chiba thought as he tries to see more clearly through the small gap, even with the bright lights almost causing him to be blinded for a moment.

"Feelin' good today with my delicious gun!" He points the gun at Rinka's direction and fires, just missing Rinka's head as she is peeping through the gap of the seats and went back to hiding completely. 'H-He fired through that small gap?'

"I never forget the position of my enemy once they fired. Used to be an army man. All that experience taught me how to pinpoint my enemy's position and the sensation of my guns by taste." He puts his gun in his mouth and licks it. "There should be no more gun stolen out there."

"Hayami-san! Remain stand by! You were wise to not fire, Chiba-kun! He still doesn't know your location! I'll keep an eye on him and tell you when to shoot, so just wait until that time comes!" Koro-sensei instructed as the man is looking around to find where that sound came from.

He then finds Koro-sensei on top of a seat in the front row, after Y/N put him there and is also hiding along with Karasuma-sensei behind the seat he is on, and fires at him but it didn't even make a scratch. "Quit starin' at me!" He reloads his revolver and continues to shoot.

"Nyurufufufu! A professional gunman versus a group of junior high students? This much of a sight advantage should be fine." The man 'tch'es and reloads his gun again but didn't shoot, knowing that it won't make a difference anyway.

"Okay, Kimura! Run five seats to the left!"

"Yoshida-kun and Terasaka-kun! Move three seats to either side!"

"We've made a blind spot! Kayano-san! Move two rows forward with this gap!" Koro-sensei instructs the students as they follow his commands and moves to the spot Koro-sensei gave. "Karma-kun and Fuwa-san! Move eight seats right!"

"Y/N-chan move three rows behind!"

"Isogai-kun! Move five seats left!"

'He's shuffling them? He's making it more complicated!' He switches watching between the students who are continuing to move that are in his field of vision. 'And yet, he's telling me their names and positions in command. I'll memorize them in no time.' He tries to aim at one.

"Student number 12! Move right and continue preparations!"

"Number 4 and 5! Film the target between the seats! Use Ritsu to tell Chiba what was on stage!" Koro-sensei uses their seat numbers as the said students did what they are told. Koro-sensei then uses nicknames. "Ponytail! Move to the front-left!"
