Summary
So what if Miku just one day adds everyone who has a SEKAI into a Nightcord chat with no warning? Chaos of course!
Also I'm heavily Tsukasa biased so...
I just made this for fun since chatfics a fun to read that's it.
I promise the humor is in here somewhere… -
Ekleipsis by Hanshayukari

Summary
“Ekleipsis” is a Greek word that means “abandonment”, “to forsake” or “to fail to appear”. The English word “eclipse” derives from it. An eclipse is described as the phenomenon in which a celestial body blocks the light from another, or passes into its shadow, creating a darkening or obscuring effect.
Historically, eclipses have been interpreted as the Sun abandoning the Earth, generally seen as bad omens; but they have also been symbols of change and new beginnings.Or:

Summary
Tenma Tsukasa, the world’s future star, completely forgets everything from the past 10 years. That includes marrying Kamishiro Rui — someone he has known just as long.

Summary
After cat Miku acquires a laptop from Nene, she manages to create a virtual world based on video games. Blindsided by passion, she gets Tsukasa to test it for her. She may have accidentally clicked on Fear and Hunger, a game Nene played for less than an hour because it was too cruel. But that was fine because—oh, she forgot to make a way out…
At the same time, another Miku (from the streets), who had been informed of Cat Miku’s super awesome idea, coerced Akito to try it out, sending him to whatever world was currently running. When Akito didn’t come out for more than an hour, she realised that Cat Miku never told her how to get someone out.

Summary
The woman standing in front of him took his hand, eyes wide. “You!” She said, “You’re the one I’m looking for!”
Tsukasa’s eyes widened. Even though he had planned to fake innocent confusion to entice a good story, he was genuinely terrified by the crazy look in her eyes. “Uh— What?” He said dumbly.
She catches herself, and takes a step back to give him space. “Oh, I’m so sorry! I was just so happy to find you here. We have an opening for an Idol show we’re doing, and it seems to me you’re the perfect candidate. So, please, please, PLEASE join our program! I’ll take care of literally everything!”
And because Tsukasa was trained to lie, he flashed a confident smile that he didn’t really feel. “Well, it seems to me you’re the expert here. Why not?”
Tsukasa Tenma has been sent to another universe. And he must Debut.... Or Die.

The You That Hides No Longer by Annacrane

Summary
"Behind a lightpole, almost flickering at the edges, was that cursed reflection he kept on seeing. But this time the reflection was given physical form, becoming more than just a trick of the light. It had almost seemed like the world in the proximity of that being had dimmed, turning exceptionally dull in contrast with the bright Sekai all around it.
Tsukasa could feel his breath get caught in his throat, his heart feeling like it was skipping one too many beats. He could only stare back at this mirror image of himself in fear, and almost awe– he couldn’t believe what was happening. The Sekai was already otherworldly as it was, but this was edging on uncanny horror."
----------
Everyone has that part of them they wish to hide, the ugly part of yourself that doesn't deserve the light of day, and Tsukasa was no exception. But what happens when that part of him no longer wants to hide in the shadows.

Summary
a demon slayer fic
They did it. They defeated the demons; they defeated Muzan.
But at what cost?
Amidst the Butterfly mansion, there is a stark silence; an emptiness that does not suffice the loss. Of course, all the Hashira and slayers put their lives on the line to emerge victorious, and they would do it again–
But what if they could do it again? What if they had the opportunity to turn back the clocks, even for a short while, and prevent the evitable?
Giyu and Sanemi, despite their differences, can agree on one thing: the battle sacrificed much. Too much. Their collective dwindled from nine to two– thus, when a letter came by to suggest such an absurdity, the two Hashira couldn’t help but pursue it.
the hashira (+extras) "stuck in a room" (ubuyashiki mansion) for as long as they need to stop hating each other

Summary
Giyuu finds himself conflicted in this very moment, wondering what in the timeline is at stake should he strike, because the annals of history are so easily altered that Sabito is standing next to him today (his own sword unsheathed and one of his hands tugging at Giyuu’s arms so hard his fingernails are digging divots into his skin.)
He worries at his bottom lip, and registers the movement of the Lower Moon, who rudely has not waited for him to finish his rumination and was unleashing a demon blood art, whose exact skillset he does not remember but reacts to on instinct.
Giyuu is struck by immense Deja Vu as he decapitates the demon once more.Tomioka Giyuu has no intention of becoming the Water Hashira again in this bright new world where Sabito is alive.
Sabito takes in a deep breath. “WHAT IN THE WORLD WAS THAT?!?!”
But really, old habits don't seem to die (even when he already did).
And why does the Upper Third remember his name in a world years before Giyuu('s reckless ward Tanjiro) ever gives it to him?Series

The light of the sun was finally able to burn the demon king's body into ashes yet what greeted them was the birth of a new demon king “Tanjiro has turned into a demon! Kill him before he murders someone!” That was the last thing Giyuu shouted before Tanjiro pierce through his heart.
