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
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
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
Deku invites some of his classmates to chill for the weekend. They are all really surprised at his house bills and his relative list. And then they find the other house. They met and everything bad that could happen happened: including MANY emergency calls, MANY fire alarms, MANY murders and a lotta chaos. :D
This is my first fanfic so… idk.
I didn’t add archive warnings but if you’re not interested in smut then don’t read Chapter 6, 11 and any other Mineta/Okajima pov.
If anyone would like to add prompt, please do. (My ideas will run out sometime)

Summary
Karma and Nagisa celebrate their third year anniversary by going to a café. If they were any other couple this would probably be fine. However, Karma needs to hide their relationship as he’s going for a promotion and being gay is a bit awkward in the Japanese government.
Unfortunately, Karma over supply of enemies (and lack of impulse control) means everything rapidly goes wrong.
Maybe Nagisa should have become an assassin after all.

Summary
“You’re a complete psychopath sometimes.” Gakushuu said to him, now finally making eye contact. His Violet eyes were full of contempt and… something else.
“That’s your type, isn’t it.” Karma teased.
————————————————————Karma thought he and Nagisa were soul mates, but a misunderstanding and his abandonment issues cause him to sabotage the relationship.
Despite everything, Gakushuu can’t help liking Karma. His upbringing has taught him toxic relationships are normal and red flags are go signs. Karma finds himself drawn to the power he has over someone so unconquerable.
Ren still likes Gakushuu, of course he does- he’s perfect. But when you view someone as an idol can you see the real them?
Nagisa realises how difficult it can be finding yourself after spending so long defining yourself by your relationship to another person.

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.
