Summary
Terasaka never asked about Shiro and Itona doesn't like talking about it. Eventually he stopped talking about it all together. That was around the time he started showing up with injuries he refuses to explain.
Meanwhile Karma and Nagisa eventually get together but trying to be a couple while attending different High Schools isn't easy. And for some reason Asano is attending Nagisa’s school.
Despite all of Class E being scattered about the bonds they built are strong and they all stay in touch. Which is nice because they're all still low-key famous for being the class the Monster who destroyed the Moon took hostage.
Things get especially interesting when a mouse is discovered floating around in outer space. Seemingly trapped in a perpetual state of dying.

The Grey Side by DarkSoul7714

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
Karma twiddles his thumbs, wondering if Asano is ever going to text back about tomorrow.
“It was last minute, dear. He might not be able to come,” Karma’s mother says, slipping past him to sit down at the table next to him.
“I guess, but he could-” He’s cut off by his phone dinging.
Can’t come, grandparents dad mad.
That’s the whole text, and Karma stares at it for at least two minutes before texting back a question mark.

But, this brought with it its own set of problems.

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 chair beside Karma’s bed is cold. Nagisa doesn’t notice until his hands start shaking again, until the chill sinks into his bones the same way the silence in this room has.
"You always said you'd never let yourself end up like this." He forces a smile, but it dies fast. "Too smart, remember? You said I was the one who'd end up in a hospital bed first despite your recklessness."
He laughs once, it's sharp, bitter. "You were wrong, dumbass." The only reply is the soft hiss of the ventilator.

Summary
"Miyo-oh, god-"
"STAY AWAY!" she cried again, pressing herself back against the wall, shaking from head to toe.
Nagisa's throat tightened, tears burning his eyes instantly. "Sweetheart... please," he whispered, stepping forward a fraction. His voice cracked under the weight of it.
Her sobs tore from her like something primal. "I don't want this! I don't want to be here-I hate this life! I just want it to stop!"

And Then... Some Bull Shit Happened... by The_Dawn_Knight

Summary
Remember the scene where Nagisa’s Mom tried to make him burn down the school? Well, Korosensei had multiple mini-adventures with the other students throughout the year that he taught them all. Helping them through traumas, having fun, and learning lessons along the way.
Wanna know what Itona and Terasaka were up to?
This is a retelling of Assassination Classroom (and possibly for some time after). Focusing on how these two idiots fell in love. All while dealing with things both out in the open and behind the scenes. Like that time they fought a Yakuza boss. Or the time Terasaka’s X girlfriend came to try to get back together with him. Or that time bullies from Itona’s old school showed up. And then there was the shit that went down with Itona’s caregiver after Shiro. Then there was the time the Big Five tried to get Terasaka to join as a 6th member after they learned what his parents actually do for a living.
Ah good times…
