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 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.

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
“Elemental magic and were-creatures - those humans who have the ability to shapeshift into an animal-like form - are deeply ingrained in the history of our society. But now, in the modern day, these abilities are mostly arbitrary, and possessed by a minority. Those of you who have these abilities face the same challenges as everyone else - school, homework, sports clubs, getting into college, getting a job - with neither advantage nor disadvantage...Or, at least, that’s what I wish I could tell you.”
Annette, a werewolf who runs a bar in the heart of the city, slowly adopts a gaggle of volleyball-obsessed teenagers in need of a safe place to exist. Because growing up “different” is hard, and the best way to face down challenges is together.
Featuring everyone’s favorite parents, Daichi and Suga, Noya but with the ability to shoot lightning out of his hands, Asahi as a werebear with anxiety, Kuroo and Bokuto as college roommates, Ushijima with too many potted plants, and many more!
Note for transparency - despite the use of were-creatures, this is not an A/B/O fic, and there are no “animal-based” relationship dynamics. Sorry if I got anyone's hopes up (up? down? idk...)

Summary
Never in his 15 years had Nagisa thought he would have to be in a fake relationship to protect his class's secret. But here he is, in a fake and unhappy relationship with a student from the A-Class.
And a jealous Karma who is unable to admit to his feelings for his best friend.

Summary
Nagisa Shiota has always been invisible. People glance right past him, even those who should know better. That changes when he unexpectedly crosses paths with Gakushuu Asano. For some reason, they keep running into each other, as if the universe has decided to push them together. Each encounter leaves something behind: a feeling Nagisa can’t quite name. For the first time, being truly seen is both terrifying... and exactly what he’s been craving.
Gakushuu Asano, on the other hand, has built his life on perfection: Top grades, a flawless reputation, and total control. Nothing slips through the cracks. Until Nagisa Shiota came along. There's something about Nagisa that Asano can't get out of his head. The more their paths cross, the more his perfect mask begins to crack. If he wants answers, he might have to risk breaking the rules he’s lived by his whole life.

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
With that final push, Nagisa lifted his head and looked directly at Karma, avoiding his intense gaze. He forced himself to speak the question that’s been burning on his mind since that morning. He forced himself to not think about the worst that could happen, and only on the best possible outcome. Anything to get out of the new reality that he was painstakingly living through.
“Karma-kun, I need you to be my fake boyfriend!”
As soon as he spoke, he swore he heard a pin drop.

Summary
The chair beside Karma’s bed is cold. Nagisa doesn’t notice until his hands start shaking again, until the chill sinks into his bones the same way the silence in this room has.
"You always said you'd never let yourself end up like this." He forces a smile, but it dies fast. "Too smart, remember? You said I was the one who'd end up in a hospital bed first despite your recklessness."
He laughs once, it's sharp, bitter. "You were wrong, dumbass." The only reply is the soft hiss of the ventilator.
