Mysterious Transferee (Assassination Classroom Reader-Insert)

Isogai goes to the front and notices a piece of paper on the floor and picks it up. He sees a map in front of the paper and he turns it around to see a note.

"All of you must come to the location in specified on the map before 6:00 tonight." He reads it aloud for everyone to hear.

"Just like with Takaoka and Shiro. He must be going to use us as hostage and lure out Koro-sensei." Chiba states as Sugino punches his desk in frustration while letting out a few curses.

Y/N goes towards Terasaka and gives him his new P.E. uniform as Terasaka understands what she's trying to convey. He shows the uniform to the rest. "We'll be usin' this."

Rio stands up and looks at the both of them. "To protect someone, right?" Y/N nods as her gaze is full of seriousness and worry for Irina-sensei.

"Greatest assassin or not, we won't let his plan go off without a hitch." Terasaka said while the others agree with him.

Night time came and they are now hiding behind some bushes outside the meeting place. Itona is scouting the area using a drone with a camera attached to it, his own invention.

"Is that the way inside?" Maehara asks as he looks at the only small building with one door as an entrance using his binoculars.

"I checked out the area around it and there's no one around." Itona informs as his drone lands back on the ground.

Sumire looks at her phone where Ritsu is shown. "Ritsu, if we're not back by midnight, inform Koro-sensei about this." Ritsu nods and tells them to be safe.

'He's probably going to hack her later.' Y/N types a message, a code to be exact, to Karasuma-sensei.

...---...

'I hope Karasuma-sensei knows Morse code and since I did not tell him the details, I'm not breaking his sick rules.' Y/N thought, referring to the rules the Reaper made.

Justice runs first towards the door as the others follow after.

'He's probably monitoring us...oh, well, I just hope Irina-sensei is fine and... I really need to control myself.' Y/N looks around and goes to the door.

Isogai opens it and they immediately went inside. The room inside had a big space, as Maehara said. Two walls facing each other have the same style and color, grey with small columns lining up the wall both horizontally and vertically as fluorescent lights line up at the center of the ceiling.

But Y/N is wondering why does the other wall facing the entrance looks like that it's not connected to the room and it has a different color scheme, pale grey mixed with brown.

'It's structure is identical to an elevator...' Y/N turns around and looks up. 'Does he really think that no one will notice that or did he intend to do it?' She glares at the CCTV beside a horn speaker. The speaker starts to create a static ringing sound as someone speaks through it afterwards.

"Is that all of you? Okay then, I'm closing it up." The door closes as Karma stands beside Y/N and also looks at the CCTV.

"So you can see what we're doing? 'Reaper'? More like 'Peeper.'" Y/N softly slaps his left arm as he just gives a smirk at her.

"We kept our end of the trade! Give Bitch-sensei back to us and this'll be over." Kataoka loudly exclaims, knowing that he will hear them.

The whole room starts to go down as Karma stumbles a bit but Y/N holds him in place as he looks at her in confusion. He wondered why most of them, since some are leaning against the wall therefore stabilized their balance, had a difficulty in remaining their standing position when the room starts to move but she didn't.
