(Important-ish)

Hello again, Reader-san!

So this is the second last chapter to this book! And if you didn't know, please keep in mind that this book will only cover the first season of the anime!

So the sequel is going to be about their high school life (Yeah, I've decided). Sorry if you wanted the second season too! XS

Enjoy!

Nagisa's POV

Karasuma-sensei was choking one of the guards as everyone looked at him with shock. "I can finally move my body again to a certain extent..."

He dropped the now unconscious guard, "I've only recovered about half way, though."

Kimura-kan said, "Even at only half strength, he's still so much stronger than us."

"Everyone," A smiling Ritsu said from our phones. "I hacked into the personal computer's camera on the top floor. We can observe the situation above."

Hearing that, we all looked at our phones.

"The upper area has been reserved. As far as I can tell, the only one remaining is... this man here." She said.

We saw the back of a man looking at a TV screen. He seems to be smoking and he's looking at the others who got infected with a camera.

"This guy... He's the mastermind, huh?"

Yoshida-kun said, "Isn't that everyone who got infected in the TV screen? They're being recorded?" He asked.

"Regarding that boss, I've figured something out." Koro-sensei said in my hands.

"That mastermind is not an assassin. He hasn't put the hitmen into proper use. Had they displayed their skills to their fullest extent, it would have been a fearful situation."

Chiba-kun said, "...Indeed. We won the previous firefight through tactics, but... That man didn't miss his target by even 1 Cm."

Koro-sensei looked at Karma-kun, "Karma-kun's situation as well."

Karma-kun looked at him.

"Had the enemy not been guarding the hallway, and had instead snuck up behind us like he normally does, you would have most likely been killed instantly from the power of his grip."

Karma-kun smiled, "...I wonder."

...Just the thought of it scares me...

Karasuma-sensei said, "Now, we're running out of time." We all moved forward.

I then noticed something.

Terasaka-kun was acting strange. He looked like he was shivering almost.

I touched the back of his neck. It was burning hot. He seemed surprised by this action and looked at me.

I said in a low voice, "You have a high fever, Terasaka-kun. Are you... infected by..."

He cut me off by putting his hand over my mouth, "Shut it."

He said, "Physical strength is all I got. I'll get better eventually."

I removed his hand from my mouth. "But... That's so reckless."

"The reason Karasuma-sensei got hit by that gas... was because I jumped ahead. And before that, there was a time when the class was about to get killed by me, too." He said.

"I can't let this take me out and drag you guys down anymore."

"Terasaka-kun..."

After that talk, we went up to the top floor.

Karasuma-sensei unlocked the door with the key card he got from the 9th floor.

We got through the door. The students started walking with a walking method called "Nanba", a walking method said to have been used by ninjas.

We went into the room.

We saw the man watching the TV screen at the other side of the room.

The suitcase next to that guy with the wiring is the antidote for the virus infecting the others. The wires are hooked up to a plastic explosive detonator.

And that remote next to him must be the remote for the detonator.

We closed in on him slowly after Karasuma-sensei looked at us to remind us the plan.

We closed in...

"Itchy." The man suddenly said. "Thinking about it makes me itchy."

"Because my wounds are always exposed to the air, my senses have become sharp." He said.

Suddenly, he threw dozens of the same remotes into the air, one by one falling on the ground.

We became shocked.

"I told you. I originally came prepared to kill a mach 20 monster. I made spare remotes so that it wouldn't get stolen."

I started to sweat. "This voice... I've heard it before." I thought.

"And... It's filled with even more malice than before."

"What's the meaning of this..." Karasuma-sensei said.

"Takaoka!?"

The man turned around, revealing Takaoka, much more different than when we last saw him.

"What naughty children..." He said.

"Guess I have no choice. I'll give you guys supplementary lessons for your summer vacation." He smiled.

He stood up, "Shall we go to the roof? I've prepared a reception for my dear students."

We looked at him with fear.

"Takaoka-sensei just laughed it off, with a face etched with madness and hatred. What I can recall, is the memory of my classmates in pain...!!"

Third Person View

The class followed Takaoka to the roof heliport.

"Did you have a change of heart, Takaoka? You hired hitmen with money stolen from the Ministry of Defence, and you violently threatened students with a virus!?" Karasuma-sensei said.

"Hey, hey, I'm extremely upright!" Takaoka said. "This was a plan to save the world."

"I'll respond to my lowered reputation with results. I'll return the humiliation I received with even more humiliation." He said.

He pointed at Nagisa. "Especially you, Shiota Nagisa. I'll never forgive you for tainting my future!!"

"...!!" Nagisa felt chills run down her spine.

Karma went in front of her and said, "Heeh, so that means you called Nagisa over to clear your resentment."

He said, "Would you really be happy from going all out on this little guy? I might be able to provide you with a little more entertainment, though."

He was giving off a glare that said "If you want her, you'll have to go through me first."

Terasaka said, "You're going senile. You just lost to Nagisa with the rules you set yourself."

He said, "Let me tell you something. Wether you won or lost back then, we still would've hated your guts."

"I never asked for you rug rats for your opinions!!" Takaoka shouted. "Don't forget that I can get rid of half you damn rug rats with the tip of my finger!!"

"..."

Takaoka went up the stairs, taking the antidote with him. "Hey, shrimp. Come up here alone. All the way to the top of this heliport."

Kaede turned to Nagisa, "Nagisa, you can't go."

"..."

Nagisa gave Koro-sensei to her. "I don't want to, but... I'll go." She walked forward.

She looked back with a smile on her face. "If he's that agitated, who knows what he'll do. I'll try to talk to him and calm him down, and I'll try to get him to hand over the antidote without destroying it."

"Nagisa-san..." Karasuma-sensei said.

"Nagisa." Kayano followed.

She kept walking, until she felt someone grab her by the hand, refusing to let go.

She looked back to see Karma holding her back. "Don't go." His voice was full of concern.

She smiled, "Don't worry. I don't plan on dying tonight."

He pulled her into a tight hug.

She rubbed his head and put her other hand on his back.

It took a while for Karma to let go, but he eventually did.

Nagisa smiled at him one last time before going up the stairs, where the final boss was waiting for her.
