Summary
Sometimes I wonder why I still bother using these words. Class, classmates, classroom…
The blank hall where our wheelchairs are lined up in neat rows next to each other, with armed guards standing by the walls keeping an eye on us, is nothing like any classroom anywhere in the world, and my classmates… well. Fellow prisoners would be closer to the truth. Or fellow test subjects, perhaps.
But our teacher, then… she is the single thing that helps us to forget the reality around us. Today, too, Yukimura-sensei’s smile is as bright as ever.
And today, the illusion of normalcy is broken even faster than ever before.
Project 3-E: a group of infected teenagers in a world ravaged by a mysterious disease, who are trained to be the saviors of mankind.That's the plan, anyway. Some of the kids might have different ideas. And then there is, of course, the master assassin lurking around who appears to be quite interested in what is going on behind the closed doors of the lab.

"casual lack of concern; indifference""Something about me must have really pissed you off yesterday." He grinned.
I then watched this redheaded devil-incarnate sit on his desk, face me, and tilt his head innocently with a cute, boyish smile.
"Listen..." I sighed and paused, not knowing what to call him.
"Karma," He just kept smiling, and I just rolled with it.

Summary
After a certain amount of time passes, life for you becomes more normal when you're dealing with cryptids, yokai, and cosmic aliens that share information that should be beyond understanding.
Or,
A-Class gets the unfortunate experience of what it's like to witness the supernatural in front of their very eyes, rather than looking through a small window attached to a building on top of a hill.

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
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 - Sapphire_1212)

Summary
Sometimes, watching Karma’s easy stride fade down the hallway, Nagisa couldn’t help feeling that they lived in two completely different worlds—one where consequences never stuck, and one where even breathing wrong could earn a reprimand.
He felt like an eleven-year-old again—naive, small, and secretly wishing he could be just like him. To act like Karma did. To go home to a place where he wouldn’t be judged… or maybe to an empty house altogether.
He’d thought more times than he cared to admit how much easier that would be. But he never said it aloud. He didn’t know how Karma would react to that sort of comment, something that bold, coming from him—and he wasn’t eager to find out. Mostly because Karma hadn't shared what he really felt about his own situation at home, so Nagisa was afraid he would be stepping over unstable terrain.
He sighed softly and shook the thought away, tightening his hold on the chocolate shake before sitting down in his seat.
Class E was meant to feel like the end of the world. It made Nagisa the target of judging stares and sharp remarks. Yet, despite it all, he ended up discovering how an old campus could feel more like home than his quiet apartment ever could.

The Grey Side by DarkSoul7714
Fandoms: Assassination Classroom, 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
02 Dec 2025

Summary
In a world filled with quirks, people often view morality as black or white: heroes are good and villains are bad. However, true morality resides in the grey area, a place where complexity and nuance exist.
Many individuals choose to remain in their comfort zones, living bound by the shackles of ignorance, as in Plato's cave. They prefer the familiar shadows of their beliefs, for stepping into the light of truth can be terrifying. This truth has the power to shatter illusions and challenge the foundations of their understanding.
Those brave enough to seek and share this deeper truth often face rejection and scorn. Society, uncomfortable with the grey, shuns those who disrupt the peaceful ignorance of the majority. Consequently, many who see the true nature of the world keep their insights hidden.
Among those who navigate the grey area are assassins. They understand the complexities and contradictions of existence and embrace the moral ambiguity that lies beyond the simplistic labels of good and evil. In doing so, they reflect the profound truth that our understanding of right and wrong is rarely as clear-cut as we would like it to be.

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
Kuroko Yua's final year at Teiko Middle School was supposed to be smooth sailing with no interesting events after her brother and the rest of the Generation of Miracles graduated and moved out to different high schools. But all of that changed when seventy-five percent of the moon exploded over night and she found herself being blackmailed by meddling principal's with terrible teaching philosophies.
Now transferred to class 3-E at Kunugigaoka Junior high and tasked with an impossible mission: to kill a super being with speeds clocking up to Mach twenty before graduation. She most certainly won't be experiencing a calm third year focused on helping her older brother beat all of their friends at a game they used to love.
A year filled with friendship, basketballs, ammunition, and far too many tentacles lays in front of her. All she can hope is to save the world and for her brother to save their family.

Kiss of... by Yadontsay

Tags
Summary
Each kiss was deliberate, and each word was heavy, but they were brimming with sincerity. “I love you.” A small, broken giggle slipped past Tenma’s lips despite the tears still glistening in his eyes. Shindou’s tenderness was overwhelming, a reflection of the way Tenma had kissed him earlier—soft, unhurried, filled with unspoken emotion.
“I love you, I love you so much, Matsukaze Tenma.”
Or; sometimes words aren't enough.
