Summary
"Koro-sensei always wanted me to be myself, so I did."
8 years after the death of Koro-Sensei, the world seems more at peace, with the forever crescent moon shining a new beam of hope. This is shown with Nagisa Shiota, a student-teacher at Paradise High School working on the delinquents of 3-5, shaping them up to be better than him.
Unfortunately, this is far from the truth.

Summary
Nagisa becomes an assassin and he's been assigned a target who works in the government, except his security is top notch and Nagisa can't even get close to his target unless he uses his old friend from junior high, Karma Akabane.
He has to manage lying about not using Karma just for his assassination while trying to find out more information about his target, not falling inlove with Karma and trying to do other assassinations on top of it all.

Summary
This is a rewrite of a story I posted a while ago. I wasn't happy with how the original turned out. When you read it, it feels rushed and kind of messy, so I decided to give it another shot.
Class 3-E finds out that Nagisa had a boyfriend, and let's just say they did not see it coming. They’re shocked, a little weirded out, and, honestly, kind of glad it ended, but what no one realizes is that Nagisa never got over him. Now, those feelings are returning, whether he wants them to or not.

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
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
**"They called me a monster before I knew how to speak. But monsters don’t protect their sisters from burning cities. Monsters don’t play lullabies for lost children. Monsters don’t try to save the world… when they’re still learning how to survive it."**
Karasuma Aizawa Izuku was never meant to be a hero. Born of legacy and secrecy—marked at birth, hidden by guilt—his story begins with fire, betrayal, and a name buried to keep him breathing.
From war-torn villages to underground labs, from orphanage traps to blood-soaked vigilante nights, Izuku carries every scar like a roadmap etched in pain. But even at age ten, with ghosts in his shadow and powers stitched from ancestral silence, he never stops running toward the people he loves.
This isn’t just a retelling—it’s a resurrection.
A multi-arc epic of survival, identity, found family, and the kind of love that rebuilds broken children into legends.This book also draws inspiration from other books and movies like *The Promised Neverland* and *Pan’s Labyrinth* for some arcs so please be advised.

Summary
Have you ever wondered what really happened in those last 15 years of the gap after Koro-sensei's death and the start of the main story, 'My Sensei is an Assassin'? So here it is, an anthology series that will tell you about what happened in that time gap in pieces.
Read my other story first. Well, it does not matter if you read or not.
The arcs are jumbled up, so be careful what you are reading. Some are romantic and light-hearted comedies, while some are dark as void with torture and gore.

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
NAGISA has been through a lot with Hiromi and her mental instability, and last year he lost his only friend that he could ever fall back on. Losing that trust and having no one else who could help him with his situation, he closed himself off and finally took some of his "mothers" advice. He muted himself and promised himself to try and keep his mouth shut for as long as he was stuck in Hiromi's grasp.
KARMA cut off his friendship with Nagisa to appease his instinctual need to get away from something as dangerous as Nagisa, or whatever was cultivating inside of him. Realizing too late after cutting off their friendship, Karma worried about Nagisa and his life at home. Trying to talk with Nagisa and get their friendship back backfired quickly and left him with more worries and fears as Nagisa left him with a written threat to keep quiet about his mother and not a single sound out of the already quiet blue haired boy.

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
“I don’t care if he’s not human.” He yanked the knife out of the paper and let it drift to the floor. “I’ve always wanted to kill a teacher.” This was certainly a very interesting opportunity.
For the first time since his suspension, he felt a surge of energy. He hasn't felt this alive in a long time.
He smirked, eyes gleaming in the dim light of the room, looking much to the devil others had always called him.

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.
