Summary
the story is pretty basic. Tsunayoshi Sawada (a girl in this story because i can't for the life of me get into the mindset of a dude) is sent to Kunugigaoka and has to be an assassin.
Just like mentioned in the title, this is a Katekyo Hitman Reborn! x Assassination Classroom fanfic. There are a few out there and not enough that i was satifide with. anyway i liked that type of idea and wanted to do my own story to it.
The twist is, the whole khr side of the story is pretty much an AU type of stuff while the main story follows the one of Assassination (with a few khr twists of course).(I'm also updating on Wattpad)

Summary
“Elemental magic and were-creatures - those humans who have the ability to shapeshift into an animal-like form - are deeply ingrained in the history of our society. But now, in the modern day, these abilities are mostly arbitrary, and possessed by a minority. Those of you who have these abilities face the same challenges as everyone else - school, homework, sports clubs, getting into college, getting a job - with neither advantage nor disadvantage...Or, at least, that’s what I wish I could tell you.”
Annette, a werewolf who runs a bar in the heart of the city, slowly adopts a gaggle of volleyball-obsessed teenagers in need of a safe place to exist. Because growing up “different” is hard, and the best way to face down challenges is together.
Featuring everyone’s favorite parents, Daichi and Suga, Noya but with the ability to shoot lightning out of his hands, Asahi as a werebear with anxiety, Kuroo and Bokuto as college roommates, Ushijima with too many potted plants, and many more!
Note for transparency - despite the use of were-creatures, this is not an A/B/O fic, and there are no “animal-based” relationship dynamics. Sorry if I got anyone's hopes up (up? down? idk...)

[PODFIC] Senbazuru by MixterGlacia for Shrineart
Fandoms: Assassination Classroom, Ansatsu Kyōshitsu

Tags
Summary
You'd been lead into another office and given a brief overview of your new job. There’d been files on each student you were to take care of which he had handed over to you. Another file you were shown but not given a copy of. A dossier on your new coworker, an unkillable creature of speed and brilliance.
If it weren't for how straight laced and intense Mr Karasuma had been you would have thought you were being hazed...
That had to be it, right?You'd read over the file, you'd seen the photos, you'd signed a non disclosure agreement and here, days later, you were trying to work out just what you'd gotten yourself into.

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. ]

The Merge by Animefan77_fiction

Summary
The Board of Education proposed a merge in the top three school in Japan. Yuuei High, of the top pro hero’s in the lime light. Kunugigaoka High, the school with the most underground “Hero’s” (more like assassins). And lastly, Jujutsu High, who works closely with otherworldly activities. What happens when the reason for the merge comes to light, and how will the student at all three schools manage to save a world that could be in danger?
(Basically I wanted to right a story about the three school’s merging and throw in some SubVerse undertones)

Summary
"I know that you are afraid of what will happen next, but you can trust me when I say that I will not allow you to go back to her and that I will find a place for you to stay if that is what you want." Nagisa nodded to that. Slowly, tears formed in his eyes. He was glad to have a teacher like Karasuma.
Someday Nagisa will get the parent he deserves.

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
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
Nagisa Shiota has always been invisible. People glance right past him, even those who should know better. That changes when he unexpectedly crosses paths with Gakushuu Asano. For some reason, they keep running into each other, as if the universe has decided to push them together. Each encounter leaves something behind: a feeling Nagisa can’t quite name. For the first time, being truly seen is both terrifying... and exactly what he’s been craving.
Gakushuu Asano, on the other hand, has built his life on perfection: Top grades, a flawless reputation, and total control. Nothing slips through the cracks. Until Nagisa Shiota came along. There's something about Nagisa that Asano can't get out of his head. The more their paths cross, the more his perfect mask begins to crack. If he wants answers, he might have to risk breaking the rules he’s lived by his whole life.

When the fates warped, however, he found himself dropped in the middle of a different world – one without magic, but one with an alien who had blown up part of the moon. A new identity, a damned school, and an alien teacher welcomed him with open…tentacles. Everything was new, yet some things remained the same, such as–
