Summary
Izuku’s life doesn’t just veer off course - it detonates.
After the sludge villain incident, after Bakugou leaves him broken and bleeding in an alley.
Instead of a hero's rescue, he gets the Hero Killer.
Instead of safety, he gets dragged into the League of Villains and tied to a debt he never asked for and can’t refuse.
It should’ve been the end of everything he hoped for. It should’ve been the worst thing that ever happened to him.
And maybe, in some ways, it was.
But somewhere between becoming Stain’s personal informant and the League’s analyst, Izuku starts to understand something:
He isn’t nearly as powerless as he used to be.

Summary
You wake up as someone who has nothing left to lose, stranded in an Underground that's slowly dwindling in life. Despite being capable of crossing the barrier, you don't dare to, when you have a personal endeavor and promise in mind.
It's a different story when you're transported into an ideal alternate timeline, where your oath is rendered void. Here, with your various counterparts, you don't appreciate reliving the life of a prisoner-- especially when it's enforced by a reflection of what your Sans could've been.
(OR: In a pacifist timeline, an alternate Sans possessing a human soul appears, risking the newly established peace between humans and monsters. If Classic Sans had hair, he's pretty sure he'd still end up bald.)
[A Various x Sans!Reader fic.]

What's all this business about heart attacks?

Summary
Hey, so. Basically. I am terrified of writing porn, but I thought this would be a good foray into writing it more often. What better way to do it, than writing 31 fics about Error having. sex.
It sounds weird when I type it.
Basically, this is mostly just going to be Error ships, probably no Errorink, but if enough people like this fic, I'll take requests for Error ships to write about.
The kinktober list used for this collection is by DREAMLANDCREATIONS on tumblr. It isn't mine, so thank you to them for making it.
Current ships included in the fic:
-Errormare
-Errordream/Insomnia
-Errorkiller
-Crerror
-Horrorerror/Herror
-Errorberry(THIS COLLECTION WILL BE CONTINUED! I am one of many who struggles to keep motivation, and procrastination kicked my ass particularly hard this time. It might not even be finished until next october, but hey! It'll be my first finished multi-chapter. I'm excited for that.)

Summary
When Sci had gotten trapped in the Save Screen with Geno, a future version of himself, he wasn’t sure if he would ever be able to get out. With Geno’s help, Sci had escaped, promising to come back and get Geno out as well. In another multiverse, another life, this goal was accomplished, and they both lived free and happy.
This is not that multiverse.
In this life, it’s been years since Sci had escaped the Save Screen. When the tracker he constructed finally located Geno’s signal and created a rip in reality to lead him straight to his friend, he stepped through without a second thought.
Now he’s trapped again, and instead of finding Geno as he’d intended, he’d unintentionally stuck himself in the Antivoid with Error, a destroyer of universes who tries to kill him at first sight. And there was no trace of Geno anywhere.
Now Sci has to find Geno, get out of the Antivoid, and avoid getting killed, all steps that Sci failed the second he left his universe.
or
Sci gets isekai’d while looking for Geno, but instead of going on a magical girl adventure he ends up becoming permanent roommates with Error. No one is happy with this.

How to Survive a Dating Sim (and Not Die) by indietrx (butakyou)

Summary
I didn’t sign up to die in the Act 3 of a dating sim—especially not as the disposable extra sister. Now I’m stuck in a fever dream with a jaded skeleton duke who hates humans, a princess stuck on eternal rewind, and a survival rate lower than my GPA. But hey, at least the villain’s hot. (Note: He’s literally bones. Send help.)
— sincerely, (y/n), probably screaming into a silk pillow.

Summary
"Is it that fun?" Teruhashi wants to project into his mind. "Not being the center of attention?"
It’s only then that she realizes while watching Saiki smile into his cup – the words “WINNER! You win one free coffee jelly!” printed across the bottom – there’s something to be found in the silence.
OR: Across every iteration of their universe, Teruhashi Kokomi and Saiki Kusuo have a lot to learn from each other. Especially when she's a psychic fixated on attention and he's a perfect, pretty boy fixated on normalcy.

Summary

Summary
“The fuck are ya doin’, Clas?” A voice called out from the entryway of the bathroom, and Dust’s eyelights jerked up to meet the red eyelights of Fell. It took every ounce of will not to immediately summon his magic and pierce through the sans variant. However, considering that there was no malice in the way the monster was speaking to him, it was easier to shove the building magic down, down, down.
Had he called him Clas? Did Fell need glasses or something?
Fell, having not noticed anything amiss beyond how odd the other skeleton was acting, was quick to move forward; wrapping a gloved hand around Dust’s wrist and pulling his bitten phalange away from his teeth. “Seriously, Classic, what the fuck are ya doin’?” Fell snarled again, agitation clear in his posture and voice.
Classic. Fell called Dust Classic.
Or;
Dust wakes up somewhere he isn't supposed to be.

Summary
“Why doesn’t he just take over the world?” Gojo asks.
Kusuke imagines a little Warp-cat popping up over his brother’s shoulder: “Yeah, why don’t you do that thing that everyone’s always telling you not to do because it’s morally wrong and also would bring you no joy because you don’t want to do it and also would actively impede your efforts to tie yourself to normality? Why aren’t you doing that?”
It’s the stupidest question he’s ever heard. Only a monster would take over the world. Kusuo, who is a god, already owns the world. He doesn’t need to take over anything.

Saiki Kusuo is Not a hero by themossgrowsonthenorthsideofthetrees

Summary
Saiki Kusuo doesn't want to be a hero. In fact, he would do almost anything to avoid that outcome. So, he hides his power, blends into society, pretends that his telekinesis really isn't that strong. He plans to become invisible (not literally, he can already do that literally) to the world of heroics, no matter the cost. And that plan almost comes to fruition... until he accidentally gets into UA.
How does one accidentally get into a prestigious hero school?
Well, it all starts with a giant robot spider, a persistent teacher, and a really fucking annoying prophecy.

Summary
edited existing chapters to make dialogue more canon like
(regained some motivation but who knows when it will be gone again)IVE NEVER WRITTEN FANFICS OR ANY KIND OF STORY BEFORE SO FORMAT MAY BE WEIRD
This may or may not end up as a kind of draft and end up being rewritten/edited once I figure out my writing style and the actual events of the story
Fanfic premises (not written yet): saiki chooses to transfer to Ouran PUBLIC high school/academy but instead ends up going to the Ouran Private Academy because of kusuke's interference. By the time he finds out kusuke meddled with his applications, the school application period has already come to an end, leaving him with no choice but to attend a school full of rich kids/nepo babies with too much time on their hands: Ouran Private Academy. How will this sudden change in plans affect Kusuo's goal of living an average life?
okay so this will be a saiki k x ohshc crossover fanfic that's a little slow paced in terms of when he will get roped into host club plot. The characters will act as closely to canon (personality and action wise) with minimum OOC behaviors unless being used to make the storyline flow smoothly.
