I wanted to write something where Izuku and Dazai were twins and saw how everything might change and connect from there. This story ended up being rather complicated but I'm excited to work on it and share it with you! Enjoy! ♡♡♡

Summary
This is an old story I posted on Wattpad back in September 2021 and decided to finally add to AO3. It's an AU using characters from the DSMP if they were experiments. I was inspired to write this from seeing someone make a post with a similar AU over on YouTube and decided to try my hand at it. I never finished this story but I made around 12 chapters so I'll be adding those here. I hope you enjoy this old fanfic, happy reading! ♡♡♡

Summary
An AU idea (inspired by this post) where Stan threw a rope to Ford as he was being pulled into the portal. He let go of his journal in favor of grabbing the rope and it was lost to Bill's dimension. Stan had saved him and for that, he was grateful. They talked and forgave each other for the past and all seemed well for as much as a day. That was when Bill's ruthless anger became apparent and he took full advantage of his deal with Ford. Thirty years later, the demon is still punishing him for his refusal to rebuild the portal.
*Now with new content! A comic that sets up how this AU diverged from canon!
*Will update as possible. Thanks for reading!Series

Summary
Mori Ougai had worked hard to earn his position as head of the Port Mafia, and he ruled with absolute authority. And, like any other who wielded absolute power, he was not someone to take an affront lightly. He was even less inclined to forgive and forget when the affront was committed by a spandex-clad man who claimed to fight for peace above all else. So, when he found himself dangling by the collar at the hands of Japan’s Number One Idiot during what should have been a routine meeting, he couldn’t help but laugh.
Finally. Something he could work with.
-
Chuuya had done a lot of batshit crazy things in his life–he’d taken out entire rival gangs with just Dazai at his side, he’d been betrayed by the people closest to him, and he’d even risen to be one of the most influential members of the Port Mafia before he even turned 16. But nothing could have prepared him for his next mission. A pro-hero? UA student? Him? And that bandaged freak was going to? What has the world come to?
-
Or Mori is attacked, so Soukoku is forced to go to UA, and Dazai wields emoticons like verbal nukes

Summary
“You will both be undertaking long term stealth missions elsewhere, but you won’t be operating together for the most part. Dazai, you’ve heard of UA high school right?”
“Of course I have, it’s like the most popular hero school in Japan or something. And now you’re going to tell me I have to live my dreams and become a hero," Dazai jokes.
The older man makes not a single sound, and Dazai turns to look at him, straight in the eyes. The corners of his mouth turn downwards instinctively.
“Wait. You’re serious? Ah, I might really have to jump off that bridge, after all,” He says airily, but he’s already planning out which bridge will be his best bet.
Mori sighs exasperatedly, “Dazai, you will be infiltrating UA high school and posing as a student there. You’ve already got experience in stealth training, but it will be a shame to let such a valuable executive go..”
-------------Dazai and Chuuya are sent on missions to infiltrate opposite sides of two parties that Mori has deemed a threat to the mafia, and to simply gather information from both sides. Is there more to this assignment than what they were informed of?

Summary
Many had marked their calendars in anticipation of what they were effectively calling “Judgement Day” for one loathsome sinner. The event itself was rather absurdist, the first of its kind, for no sinner had ever caused such an uproar that they demanded a second Judgement post-mortem.
What punishment, everyone thought, would be fitting for a man who made such history?
Once, this creature was a man whose voice and manner were adored by the many who followed him. Now, he stood alone, chained, and without the strength to raise his head.
“Let the Judgement of the Media Overlord, Vox, commence.”
--
My personal take on a post-Season 2 redemption arc for Vox, where the Speaker of God takes away Vox's voice as punishment for his crimes in Season 2- this is the Voiceless AU and a RadioSilence Fic

Summary
The Armed Detective Agency and Port Mafia are asked to investigate "amplified abilities" around Yokohama. After initial complaints, Dazai and Chuuya agree to work together. Their group manages to find the culprit and devises a plan to apprehend them. It's supposed to be foolproof but something goes horribly wrong. Dazai and Chuuya are sucked into an amplified portal which teleports them into the future. Two hundred years.
They land in the middle of a highschool and learn that abilities have become much more common and are now called quirks. As they figure out a way back to their time, they have to act as teachers for the hero course students in class 1-A, in return for U.A. to help them out with housing, I.D. and information gathering.
