Hi guys. This is an idea that just popped into my mind and I thought it would be fun to write. So I hope you'll enjoy this story, and reply if you guys want to read more. Criticism is welcomed.

It all began in the middle of the day. Everything was normal. As always. At the first period shooting some anti-sensei BBs and greeting Koro-Sensei who dodged perfectly while checking everyone's presence.

Of course Karma was the one not being there though. After that came English lessons with flirting Bitch-Sensei and her blackmailing with French-kisses if we pronounced any word wrong. And now a murderous PE lesson with Karasuma-Sensei. So just the usual stuff.

We were in our second semester. Midterms just over with all of us in the top fifty and Karma on first place. Our assassinations? Well we were the closest to get Koro-Sensei in summer. He proved to be even harder to kill now than back then.

Nagisa sat outside leaned against a tree looking over all of his notes on Koro-Sensei's weak points. Disappointed. They were useful, indeed, but sadly not able to give them victory. He sighed.

During PE some of the students got an idea. Something about science and a new mixture to create. Apparently the idea came from Nakamura and Okuda was involved, well since she is the best in that subject though. Half the class was interested and went in to see the results. However Nagisa didn't trust all of that. He can't be blamed though, after all Nakamura has only evil in her mind just like Karma.

Ah yeah, surprisingly the red haired delinquent showed up for today. He was bored with whatever he was doing before and joined the class members inside, wanting to support. Well another reason for Nagisa to stay away from it. He actually wondered if the ones inside saw his devil smirk of his or heard Nakamura's evil laugh.

Besides Nagisa was afraid to end up as their test object or something in that way

When Koro-Sensei came back, from what Nagisa remembered (if correctly), Thailand, (Sometimes the blue haired boy thought that their teacher was only boasting with his Mach 20 speed though) he was asked to help.

And so even Koro-Sensei was inside. If that was actually an assassination attempt it should be something really smart, after all they had their target help them.

Maybe this time someone else was the target. Nagisa shivered, hoping they won't do anything horrible and being glad not to have gone along.

He preferred to be here together with the other half of the class in PE. Karasuma-Sensei gave them a free choice to do whatever they wanted to, since bigger training methods didn't make sense without the whole class.

No one had an idea though what to do, so they sat down doing nothing. He alongside Sugino, Kanzaki, Kimura, Mimura, Sugaya, Takebayashi, Kurahashi, Hayami, and Yada sat there in boredom.

Kataoka, Muramatsu Yoshida and Hara went with Karasuma-Sensei to explore the mountains. Nagisa couldn't exactly remember why. It was a bit of a surprise that Kurahashi didn't joined them, but Nagisa wasn't about to ask. Maybe she was frustrated about the class' wish to bring their PE teacher together with Irina-Sensei. And Fuwa disappeared some time ago.

All the others were in the classroom. Besides the little bluenette wondered whether to admire their courage to be in a chemistry experiment thought by Nakamura or pity their stupidity.

How happened all of this again? Why did they actually go inside? Well Nakamura and Karma don't need to be mentioned though and Okuda is obvious too. Kayano went in there, being sure it's going to be interesting.

She even tried to drag Nagisa along but the boy was stubborn and refused. Okano had apparently become interested in chemistry, Maehara murmured about helping ladies or so and Isogai was courageous enough to look out for all of that.

Okajima was reading his porno magazines inside even before, maybe he didn't expect anyone to come inside. (Even though it was obvious what kind of things he did). Who else was there? Ah, Terasaka and Itona. They were simply asked if they want to come. The shorter one just shrugged and came along while the other was dragged inside by Karma.

Whatever they were going to do, Karma was definitely going to use Terasaka as some kind of guinea pig. Poor Terasaka.

He sighed. "How long are they taking?" No answer. The others simply shrugged off his question. "As long as it's safe to go back it doesn't matter", said Sugino. They sighed in chorus. "I wonder what they are going to do."

Booommmm!

An explosion. Definitely from the classroom. I knew it thought Nagisa as he stood up in panic to go see, with the others around him, what actually has happened at that time.

Getting back to the old building of their E class there was smoke. Everything was hidden in smoke. Grey filled the air and some strange kind of smell. "What the…?" the students were stunned. What on earth have their classmates been doing?!

Hesitantly they got closer to the building, while the smoke was almost gone Nagisa dared to continue. Inside was nothing but a mess. Everywhere burnt woods, destroyed things like desks chairs and so forth which must have been harmed by that explosion. Oh no! Is everyone okay? What the hell have they been doing?

"What happened?" Karasuma-Sensei followed by the students who left with him early arrived. They must have been alarmed by that sound of the explosion. "I think there went something wrong with the experiment" replied Nagisa worried. I just hope everyone is fine.

He stopped before the class. The door was blown away revealing all the mess in the room. The short boy swallowed heavily. One last glance back to his classmates who gave him an assuring nod he dared to go forward. He stepped in and froze. He froze on the spot. Mouth wide opened. So did his friends entering after him. Everyone totally stunned.

What on earth did happen?!

AN Besides I have the bat habit to include my OC's in nearly everystory (one for same fandom) and for those who know my other AssClass story I would like to know if I should include my OC or not
