Summary
Class A had quickly adjusted to everyone around them, and their weirdness was welcomed and even appreciated. They all had their quirks and eccentricities, so no one could be faulted.
But, if asked, Izuku Midoriya did have an odd habit of speaking to his watch. And leaving in the middle of class, and tensing up. at the word “Kill.”
No one brought it up, obviously, until it became more and more frequent than before.
Having been in class 3E, Izuku knew first hand how to fight villains, how to beat the and win and how to kill. His classmates didn’t seem to. This is how he juggled both lives
tldr: izuku was in class 3e and his assassin life effecting his hero work

Summary
"You're so worked up about wins and losses, victories and defeats, that you skip over defining what they mean. Is an academic genius the winner in a room of world-class athletes? Think about it! Are you truly winning against me if you're the only one invested in the competition?
Of course, mathematically, in a room of 100 people, get 51 on board and you dictate what's black and white. So? Are you going to travel the world to serve a life philosophy quiz to 8 billion people?
And between you and me, Kiyotaka. If you set your finish line simply to comply or deny another's whims, you've already thrown in the towel. You see, unlike the rest of our peers, I'm not looking to peak in 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
“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.

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
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.”

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.
