Ansatsu kyôshitsu

Nagisa Shiota:
[narrating] How did this happen? How did we get here? I mean, as far as I know, it all started with two very big things kicking off 3rd year. [a scene showing a large chunk of the moon is shown being destroyed] First, there was the moon. One minute, it's fine. The next? Kaboom. Permanent crescent. [news reports of the moon's explosion are then shown]

Reporter #1:
Uh, we interrupt our currently scheduled program for this breaking news bulletin.

Reporter #2:
This just in: A portion of the moon has been vaporized. Some sources estimate over 70%. I repeat, a portion. What does it mean? Astronomers the world over are struggling to figure out just that.

Nagisa Shiota:
[narrating] There was that. And then, there was him.

Nagisa Shiota:
[narrating] Yep, we're assassins. And our target is our teacher.

Nagisa Shiota:
[upset over Korosensei for not respecting Sugino's feelings] That's not fair. You don't know. How could you? That's ridiculous. You can't just...

Tomohito Sugino:
Look, don't worry about it.

Nagisa Shiota:
I get it, why even bother? Hey, we're just E Class, right?

Nagisa Shiota:
[shouting] WE'RE JUST A BUNCH OF LOSERS AND LOST CAUSES!

Nagisa Shiota:
[narrating] With supersonic speed and, um, multitasking tentacles, Korosensei definitely has the advantage. Killing him won't be easy, still.

Tomohito Sugino:
[to Korosensei] Can I bother you for a sec? I wanna take a couple of test shots at you if that's okay.

Koro-sensei:
[giggles] Glutton for disappointment?

Nagisa Shiota:
[narrating] He was such an awesome motivator. The kind of mentor who really knew how to light a fire in you. We were having, well, a "ball" with him.

Nagisa Shiota:
[narrating] What are the facts? This guy vaporized 70% of the moon and plans to destroy Earth in March. He can do it. The issue is how to stop him. Oh, and for some reason, before ending the world, he wants to teach a bunch of last chance junior high nobodies. The Ministry of Defense was quick to make the most of the situation. They gave us a mission: kill our teacher, save the planet. We're on board because the reward money is crazy. Ten billion crazy.

Nagisa Shiota:
Mr. Takaoka... Thank you. [tasers him unconscious]

[last lines]

Nagisa Shiota:
[narrating] The E-for-End Class is the assassination classroom. We are killers, and our target is our teacher.

Koro-sensei:
[laughs] Good morning, class. Time for a second term full of hard work in studying and assassination both!

Nagisa Shiota:
[narrating] It's ours and Koro-sensei's classroom, this assassination classroom. Another day, another class bell rings!

Akira Takaoka:
[Nagisa throws his jacket off before his fight with Takaoka] Ooh, don't you look cool! [Takaoka throws his jacket off as well]
