Mysterious Transferee (Assassination Classroom Reader-Insert)

"It's too dangerous. He threatened us so easily indicating that he might have something waiting for us." Karasuma-sensei brings Koro-sensei in front of his face as Koro-sensei agrees.

"It might be easier to just hand me over. What do you think? It's up to you." Koro-sensei looks at the students.

"I-Its..."

"Too difficult."

"They'll die before they even reach the top." Bitch-sensei worriedly said as Karasuma-sensei decided to back off.

"Nagisa-kun, Kayano-san, I'm sorry but---" Before he could finish, some of them already start to climb up the ledge.

"This just a piece of cake."

"Compared to our training."

"Agree."

Karasuma-sensei and Bitch-sensei was in shock as Koro-sensei just laughs and looks at the remaining student. "Y/N-san? Aren't you going to follow?"

Y/N smiles. "Just giving them a head start."

"This is not a game, L/N-san." Karasuma-sensei said as Y/N is already in position.

"I know, Karasuma-sensei." She starts to climb, faster than the others until she's the one in the lead and stops. "We can't do this without you, Karasuma-sensei!"

The class rep understands her claim. "Can you be our commander, Karasuma-sensei?" The others also stop and agree with them. "We'll let that jerk pay!"

"They're no ordinary students. You have a sixteen member special forces on your command." Koro-sensei speaks as Karasuma-sensei brings him up.

"Sixteen?" Bitch-sensei asks, who is standing in front of the two.

"Don't forget about me!" Ritsu appears on Nagisa's phone.

"There's not much time." Koro-sensei informs as Karasuma-sensei finally makes a decision.

He takes a step forward and yells a command at the students who are still waiting for him. "Listen! Our goal is the top floor of the hotel at the summit! Our plan will change from a stealth infiltration to a surprise attack! We'll use the same hand signals and link ups from training! You only have three minutes to memorize the map!"

"Yes, sir!" Y/N already memorized it after Ritsu showed the map and is now resuming to climbing the ledge as the others are already closing in with Okano leading.

"Don't get left behind!" Okano signals a come on with her left hand while the other is holding on the ledge. "Okano and Y/N sure are fast!"

"They really beat us at this kind of thing." Kimura and Isogai then looks towards their teachers.

"Only one of them can climb." Karasuma-sensei is carrying Bitch-sensei on his back while Koro-sensei's sling was slung on his right wrist. Bitch-sensei was complaining, making it harder for Karasuma-sensei to climb.

Both Y/N and Okano already reached the top and is now waiting for the others. "That was amazing, Y/N-chan!"

"You too, Okano-san." Once the rest has arrived, they hide behind some small pillar fences. Karasuma-sensei takes his phone out of his pocket and calls for Ritsu to do some final check of their invasion route.

"Yes, sir! Displaying interior map." Ritsu gives a salute and shows them the map. "Final check: The elevators can't be used because they require a pass card on every floor. So we'll have to take the stairs, but they're scattered throughout the hotel. We need to cover some distance by foot." Ritsu explains as the class also looks at the map using their phone.
