Summary
One ordinary afternoon, Class E vanishes.
Koro-sensei, Karasuma, Irina, and their students wake up in a world where powers are reality, and heroes walk the streets.Out of place, outmatched, and under the watchful eyes of Japan’s top heroes, the students must navigate a society that is both fascinating and dangerous.
One student is chosen to enter U.A. High — a school of heroes, where every move is a test, and every action has a consequence.But the more they explore this world, the clearer it becomes:
their arrival was no accident. Something — or someone — brought them here.
And what waits for them may change not just their lives, but the fate of two worlds. -

Summary
At the heart of Kunigigaoka Junior High’s rumour mill was Ota Haruka, a simple girl who knew everything about everyone. She thought that putting herself in Class 3-E would solve all her problems, yet they only seemed to multiply. There was that redheaded jerk who was always pestering her, she was losing her ability to make music, and her favourite video game is far too expensive…
Oh, and her teacher is going to destroy the Earth at the end of the year.

Summary
The first thing Y/N remembers is running through the woods. Besides that, she doesn't remember a thing about her past. On top of it, 70% of the moon blew up. Could these events be related or some bizarre coincidence? Join Y/N as she tries to remember her past, but also assassinates her teacher. Assassination Classroom belongs to the rightful creators. The only things that belong to me are Y/N and her backstory, as well as the slight changes to the storyline. New chapters on Mondays.

Summary
The class had come so close to assassinating Koro-Sensei, but with that absolute defence form of his, they were back to square one. But that attempt seems to have tired out quite a few of the students.
But not the ones who should be tired.
Does a slightly different group of students still lead to the same outcome? Who knows...

Summary
Basically, blame everything on their study date, more like blame it on that Akabane guy. If he didn't do that, Gakushuu would not have a new strange obsession.
Since when does hearing a guy humming end up making a band for him to sing in? Maybe Gakushuu rigged it so the universe let all of this happen in his favor, but you will not hear that from him.

Summary
The flashing lights do manage to drag him out of bed and to his window. It’s not the best view of whatever’s happening, and Nagisa can’t hear much of anything from four stories up, but he just manages to see a man being walked out to the back of a police car in cuffs. Ms. Yukimura is speaking to what seems to be a detective. It might just be his mind playing tricks on him, but he’s almost certain he sees a small black cat slink away into the forest.
He shivers hard without the warmth of his blanket. He’d overestimated ‘morning’ when he’d woken up. It’s dark and cold, and Nagisa had abandoned his blanket with his bed when he’d dragged himself up to the window. But it doesn’t really seem like there’s all that much to it. It can’t be any later than four in the morning, so he lets himself slip back into the warmth of his covers.
It takes him just a little bit too long to properly fall back asleep.

or, in the fallout of divorce, nagisa and his mother move to addison apartments.
