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 girl shot up so quickly her chair squeaked against the floor. “Nagisa-sensei!” she beamed, eyes shining with unfiltered excitement. “What’s your quirk?”
The room seemed to lean in all at once, a ripple of anticipation spreading through the students. Even the green-haired boy in the front row — who already had a notebook open — was practically vibrating, pen poised like he was about to record every word.
For a moment, Nagisa only smiled back at them, soft, calm, the kind of expression that gave nothing away and yet somehow eased the air in the room. His eyes swept lightly across the expectant faces, catching sparks of excitement, curiosity, and even a little awe. Then, with the same steady composure he had carried all morning, he answered:
“…Why, I’m Quirkless.”
or
After Paradise High School, Karasuma contacts Nagisa and sends him on a mission to UA. The goal? Monitor and teach combat to the new upcoming hero students in Class 1-A. So, Nagisa becomes Aizawa’s assistant teacher.

Summary
Just the normal events of the anime with my oc thrown in the mix :> Plus some minor writing changes to make things a bit more fun for me. Like skipping some filler arcs to put more focus on the stuff that I wana put focus on
This anime/ manga has been such a comfort series for me as someone who also really struggled in middle school and just school in general. Young me always made up so many stories of herself interacting with the characters and me as an adult want to create a work that a younger me would be happy to read.

Summary
Nagisa Shiota is a boy who's been trained to be a weapon by his father his whole life. He's a boy who's been trained to keep a facade on by his mother his whole life.

A retelling of Assassination Classroom but some themes are expanded upon! Mainly the darker ones like Hiromi’s abuse, Nagisa’s suicidal tendencies, Nagisa’s bloodlust, Karma’s depressive tendencies, etc.
It’ll start slow but pick up later.

Summary
Years ago, Nagisa Shiota and Karma Akabane forged a bond inside the walls of Class 3-E—equal parts rivalry, tenderness, and an unspoken sense of gravity. Through assassination plots and midnight rooftops, their connection burned bright, then fractured under the weight of youth, pride, and one night too many regrets.
As adults, fate pulls them back together. Karma, now polished but quietly restless, crosses paths with Nagisa again—no longer the boy he once knew, but someone stronger, still carrying the name of a child that both of them had once imagined together: Riku. The name hits harder than Karma expects. That simple memory, spoken aloud again, stirs up everything they buried.

Summary
"I know that you are afraid of what will happen next, but you can trust me when I say that I will not allow you to go back to her and that I will find a place for you to stay if that is what you want." Nagisa nodded to that. Slowly, tears formed in his eyes. He was glad to have a teacher like Karasuma.
Someday Nagisa will get the parent he deserves.

“Come on, you would be the perfect candidate for our cause!” Shigaraki finished his sales pitch and gestured to the other villains in the bar.
Bakugou didn’t buy his bullshit, his goal was to be the number one hero, not join some little villain band that felt sorry for themselves. But when he turned his eyes to look at Nagisa he felt himself freeze.
The kid looked like he was considering it.
