Summary
In a world where people can fly, blast energy beams, and shoot lasers from their eyes, it wasn't a surprise to see that things were getting out of hand. Especially when a kid manifests an exceptionally unique quirk to transport loads to different universes. Even if those loads happen to be a class of assassins and three unusual teachers.
They accepted a flying octopus that can move at Mach 20, a robot as a classmate, and a kid with tentacles coming out of his head. But a universe where eighty percent hosts some kind of bizarre power, and now including one of their own? Which happens to be Karma of all people?
That's where they draw the line.
But with Class-E getting increasingly desperate for a way home, they convince Karma to infiltrate UA as a student so he could find data of a quirk user capable of helping them get home. No matter who it is.
Let's hope the rest of the world doesn't catch wind of their temporary stay in this universe. A hard feat to accomplish since Class 1-A's constantly being broadcasted to the entire world.
Meanwhile, Koro-sensei's worried about the possibility of getting replaced by this "Aizawa." He really should have thought about that beforehand.

Summary
"Look, I really didn't mind the fact that I died and reincarnated into Ansatsu Kyoushitsu. I didn't really mind that you gave me a hole in the heart. That was a real dick move, but I didn't complain. So god, Void, whatever, I'm sorry I punched a student. Please recall my demotion into Class E. Please, the moon literally just exploded and I don't wanna be there!"
Kuma-sensei did not belong here. He knew better than anyone else that he was just an outsider.

Summary
You can't fix something that was never there in the first place. Nagisa's family dynamic was the perfect example of that. They were never a happy family in the first place
But no one needed to know that. No one even really knew what his family was like. Nagisa liked for it to stay that way, but is that really the best option?Rewrite of season 2 episode 9, Round Two Time. A lot of it is a friend of mine's ideas.
TW: implied depression, @bu$e, Hiromi Shiota, etc.

Summary
“I…” Karma rested his head in his hands as he willed the events of that morning to make themselves known to him. And for the classroom to stop performing barrel rolls. “I left the house early because…” Why had he left early? Why would he ever leave early? He never left early. In fact, he usually waited until the last second to get out of bed. Caught the last train that would get him to class just as the bell rang. Why would he…? “Because Nagisa and I were meeting up.”
“Nagisa?” Sugino’s hand came down on Karma’s desk with a bang that didn’t sound unlike a gunshot to Karma’s sensitive ears. “You were with Nagisa?”
“Take it easy.” Takebayashi pulled Sugino back when Karma flinched and groaned at the noise.
“Where is he?” Karma tried to demand, but his voice faltered.
“He never came to class…”

Unreal Assassin by Wendy_Noire
Fandoms: Assassination Classroom, Harry Potter - J. K. Rowling
31 Jul 2025
Tags
Summary
"Korosensei, why is there a child sleeping in the teacher's lounge?"
An odd question made more odd when you learn that this is the classroom of assassins. The unusual situation being discussed easily, as though this wasn't a random child, but a question on a test.
Harry Potter, the unknown hero of the Wizarding World, was never treated kindly by his aunt and uncle. One day he found himself living what must be a dream: He was being beaten by Vernon as usual when he found himself in a forest he had never seen before with a giant, yellow creature that seemed to control the scenery.
-----
Is Harry the only Wix in class 3-E? Can he help them achieve their goals? Does he still have to face the same destiny as he would before?

Summary
A Deku as Nagisa crossover fic.
His lessons on hiding the truth were from the Japanese Government itself who asked a bunch of middle schoolers not to even tell their parents that they were being trained to kill, regardless of how many times they almost got killed in return. In fact, Nagisa was still lying to his classmates at UA about that, and they got paid ten billion yen to ensure that they never talked to anyone about their third year in middle school. So why was the past slipping out? Will his classmates find out what secret's he is hiding?
Mostly focusing on the bonds between the children with some bigger events coming in. :)

Summary
A hotel to redeem the sinners of hell so they can get to heaven sounds like a stupid, but the 28 assassins taught by the moon destroying giant yellow octopus are more than used to the impossible.
3-E are Overlords, though most think they're a group of 3, each of them working together for their communal goal of a livable version of hell. If heaven scorns them and the hotel they choose to help and support, well... Aren't the End Class used to that? They were the scum of society after all. So who is better placed to help Charlie's naive plan?
