3rd Person point of view

The class sat quietly. So quiet, you could hear a pin drop. That certain fact made Nagisa concerned. Never had her students been so quiet in all the months she had been teaching them. But then again, knowing that your new teacher is an artificial life form you have to kill, might shock you to silence.

Nagisa cleared her throat ;trying to block the feeling of nostalgia. "Class, this is experiment no. 49987. He will be your teacher and your goal is to kill him before he kills us. He has a ticking time bomb built inside him and a careless employee ticked it off. You have exactly 1 year to kill him and receive ¥ 1,000,000 or die trying."

Chaos.

"How the hell are you so calm?!"

"This has to be some kind of sick joke!"

"Nagisa-sensei what is that?!"

Nagisa sighed but smiled. Reminds her of the first time she and her classmates met Koro-sensei. Irina shook her head at their expressions. Karasuma stood beside her, his face not showing any emotion, though he looked a bit annoyed. Karma had a meeting and thus couldn't come.

Nagisa, Irina, and Karasuma each grabbed a bag and began to distribute familiar green knives and guns to the students. Nagisa nearly cried at the familiar feeling. The small plastic knife that she repeatedly handed brought back memories she tried to avoid in order not to cry.

Karasuma cleared his threat and the attention was on him. "These knives handed to you were made directly from the government. They won't harm you. However.." he left his sentence trailing as he tried to throw a knife at the blue octopus-like creature. It was professionally dodged, as expected, but everyone got the hint. It would harm the failed experiment, not them.

Nagisa stared out the tinted window. The view was visible from inside but the outside was obstructed from seeing what's inside. It was for extra safety, she supposed. If anyone would show up at the mountain unexpectedly, the couldn't see what's going on inside.

Irina began the first period with language class. She sprouted language after language. French, Russian, Italian, English, Mandarin, German, Tagalog, Greek, Roman, etc. the class could do nothing but sit down and listen.

Nagisa snapped out of her train of observation. She had to find out one thing: Why was the new failed experiment teaching? She understood that Koro-sensei had a reason - a deep one in fact - but what about this new, blue octopus? What was his backstory?

"H-hi, I a-am Shizuka Misako, I- I am frum Japan. " tried one of Nagisa's few female students.

"Fryktelig!" Irina exclaimed in the same language.

Norwegian. Nagisa concluded. Irina may be a good assassin, but a teacher is one thing she absolutely can't do. She grabbed a stack of paper and began to talk to Irina in several different languages.

"You're going to hard on them." Nagisa said in concern and in Italian.

Irina waved it off and replied in Hawaiian, "I'm not! Besides, what would you propose?"

"How about you give them a break and let them choose a language they're interested in and do a research about it? They could fill these paper on why they are interested on that certain language." Nagisa said in Sweden and handed the older woman the stack of paper.

Irina thought about it for a while and looked at the students and back at the shorter girl. She sighed and spoke in French, "fine! Just this once, I'll spoil them."

Nagisa sighed and faced her confused students with a reassuring smile. "Okay, I was able to convince Irina-sensei-"

"But she said we should call her bitch-sensei." A student interrupted.

"I change my mind. Only my first batch of students can call me that!"

"I can see why they call you Bitch-sensei." A student pipped.

Nagisa smiled. This was starting to feel like home to her. Just with new family members.
