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
"You're so worked up about winning in life and being on top, number 1, that you skip over defining what that even means. Is an academic genius the winner in a room of world-class athletes? When you think about it, are you truly winning against me if you're the only one invested in the competition?
I mean, sure! In a room of 100 people, get 51 on board and you decide what's black and white. But give me a call when you finish probing half of 8 billion people about their life philosophy.
And between you and me, Kiyotaka. If you set your finish line according to other people's wishes, you've already thrown in the towel. You see, unlike the rest of our peers here, I'm not looking to peak in this Highschool. What about you?"
[A crossover between Classroom of the Elite and Assassination Classroom post-Koro-sensei death, featuring an original character and returning ones. All in hopes of a slightly different approach and feel to a COTE Story compared to most Kiyotaka 2.0 ones. ]

Summary
Karma and Nagisa’s friendship was starting to grow—not in a friendly manner. At least, to Karma.
His heart can’t help but skip a beat whenever he feels his hand brush his slightly, he can’t control the way his heart felt like it would explode whenever he laughed. But what he can do is hide these feelings and urges that were blooming inside him.
And so far, he was trying to bury these feelings down as much as possible. But Nagisa was only making it worse.Nagisa was going to introduce him to his mother, considering how long they have been friends, and because of the fact that this was the peak of their “friendship”. Especially since he ghosted him during their second year.
The problem was that Nagisa was starting to feel differently about Karma, and it was tipping him off.By this point, he wasn’t introducing Karma to his mother as a friend—anybody could tell. Although, he tried hard to hide it. Why? Because it’d be wrong to love another boy. His mother would judge him to no end.
So all he can do is suffer while he tries to disguise his feelings with platonic friendship.

Summary
Rin Hattori didn’t wish for this – certainly not. All he wanted to do was go to the studio, or maybe even the park to get some fresh air, and yet, here he was, whisked away to a different world that had magic.
At first, like a reasonable human being, he thought that perhaps, the universe had abandoned him in this fever dream. Was he so close to death that god had decided to tempt him? Surely death would be better than being stuck in a place like this, right?
Sadly, he ended up enrolling in Night Raven College.
It couldn't be helped, he supposed, forming a solid game plan. Do well enough not to fail in his academics, research a way home, avoid music like the plague, teach some goddamn English, and maybe do some art here and there while he was at it— hey, what could he say, this was another world after all. But most importantly, he resolved himself to try and keep it low-key.
In hindsight, Rin would’ve scoffed. What part of this is low-key? He wanted to scream.
(Oh, his friends back at home were going to absolutely lose it. What joy.)

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
When applying to high schools Karasuma told 3-E that the Department of Defense wanted them to apply to UA, so everyone did. Surprisingly for the dead end class of quirkless rejects, they all got into the classes they applied to.
They have a head start compared to their classmates, at least a year of playing the unwinnable game against the unkillable teacher had taught them the limits of their bodies. Then again, Karma and Nagisa were the first quirkless students in class 1-A in the entirety of UA's history, and that had a certain tone to it.
Nagisa's home life was also getting worse.

Summary
Karma Akabane, an outcast even in a group of outcasts (Not that Ritsu or Itona were any similar to the class) was always embarrassingly lonely. He'd never admit how his friends in Class 3-E had helped with his loneliness, and he'd be d*mned if he told a teacher. They obviously couldn't care less.
Or;
How Karma's life full of nothing but loneliness, turns into one with love from his friends and teachers as they unfold the harsh situation he is in.

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?

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.

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.

Summary
What use was Nagisa in a situation like this? What was one little snake – out of place, out of time and so far out of his depth he’d forgotten what the surface even looked like – to do?
“Come now, we’ve covered this,” the ghost of Koro-sensei’s voice seemed to reach across the centuries to say. “The poor beast isn’t as terrifying as all that. Start by observing how he swings that blade. Next, look over each movement with the same attention to detail and piece together what you find.”
There.
“Don’t you see?” Koro-sensei asked.
And he did. Stain was skilled and he had many blades, both literal and metaphorical. It would be near impossible for a hero of Nagisa’s skill level to beat him, steel to steel.
But Nagisa didn’t need to beat him. Because he didn’t need to be a hero, not to do this.
“Voila,” Koro-sensei said. “A trivial adversary indeed.
“Now, use that trusty blade to fillet him.”
