Shouta Aizawa after having an affair with his girlfriend, became single. He's stayed like that ever since but his girlfriend was pregnant and gave him the child. Aizawas always been fond of children so he raised the child up and named his Osamu Aizawa. But one day his son went missing, he was devastated and went into deep depression hinting some of the bags under his eyes. He became a teacher at UA when a mysterious boy is found roaming the streets alone, he says his name is Dazai. He won't mention his first name but told aizawa it was his last name. Aizawa suspects something of this boy but let's it slide, the boy banters about wanting to be a student at UA and when the time comes passes the entrance exam though sadly only makes it to the general studies course. This Dazai though is the one and only Demon prodigy from the port mafia of the city yokahama, that closed itself off from Japan years ago in a Great War when quirks appeared. (Enjoy!)

"Dazai-kun, Chuuya-kun, a new mission for you. This will be an infiltration mission outside of Yokohama. Don't disappoint me!" Dazai and Chuuya leave the boss's office after receiving the file containing information on their new mission. "These so-called heroes have been overstepping their boundaries. They've been getting bolder these days, "saving" the citizens of Yokohama." Chuuya says in disdain and anger. There's no way these heroes thought kidnapping these poor citizens meant that they were saving them from the rumored "villain's ruling". The heroes have been invading Yokohama, time to send Soukoku in to show these heroes their places! This is posted in ao3 as well :))

Dazai and Chuuya find themselves in a predicament. With little time to process Mori's betrayal, the two boys run to the outskirts of Yokohama city. Working together while soaked in blood, they climb the city's impenetrable barrier in a desperate attempt to survive this ordeal and start a new life. Their new life, now filled with a world of heroes and villains. The two boys now living in this new world under the guardianship of a homeless-looking man and a blond with an annoyingly flashy appearance and loud voice. What will become of these two tragedy-stricken boys and their newfound home? Will they heal from their trauma and become heros? Will their budding romance bear fruit? This is my first fanfiction and my first time writing something publicly like this( sorry if it sucks). This is a fan-fiction cross-mix with Bungo Stray Dogs and My Hero Academia being in the same universe. The characters may not act canonically, In this story, Dazai and Chuuya are both 15 and still in the port mafia. In this world, ability users were prosecuted in society so they had to seal themselves in Yokohama city, allowing no one to enter or leave. While on the outside world, quirks had developed and the existence of ability users became forgotten with the rise of heroes and villains. The citizens of Yokohama are aware of what is going on in the outside world but think it's stupid to label someone as good or evil. No, that is not my original idea and I got heavy Inspiration from "This Boys Too Young to be Singing the Blues", By Distonail. It's an amazing read, I recommend it. :) Ps. If you wanna skip to when they start making their way to MHA then skip to chapter 6 ;) though you will be missing some shipping material and plot lines if you do ;b #gore #Dazai x Chuuya X Arahabaki # Eraser-head x Present Mic #Soukoko in UA

Without reason or warning characters from Bungo Stray Dogs end up in the world of My Hero Academia. With no record of their crimes or even the existence of the Port Mafia the best course of action is to stay out of trouble and survive school in the world of heroes. Technically low effort as I pretty much just made it up as I went along and I didn't do any research or review, as I had no desire to rewatch My Hero Academia, and the story is more abridged than it could be. Characters and universes belong to their respective creators, I just put the crossover together. I do my best to keep characters at least close to canon and try my best to keep headcanons to a minimum. Personal rating of the story: 13+ for Dazai being Dazai, but otherwise it's quite clean. (For any potential MHA fans who aren't familiar with BSD, but want to read a crossover, I suggest just doing a quick search for "Osamu Dazai", regardless of which Dazai pops up first, it should explain the rating reasoning pretty well.) To artists, especially commission artists, please read the afterword before asking about doing illustrations/comics and please confirm that you've read the afterword if asking too. (I had to come back and add this because I keep getting asked and would like to avoid awkwardness as much as possible.)

Modern AU. The Hashira and Kamaboko squad are all students (apart from Gyomei who is their friend outside of School.) Giyuu doesn't do well at school, he has long term hypothermia from when he got lost on a mountain in a snowstorm as a kid and left unconscious for weeks, almost freezing to death. If it weren't for Urokadaki, he would have died. But now the consequences get worse. Shinobu bugs Giyuu as she discovered this quickly. But theres an angry guy who will get in the way of them.. i wonder who 😭 MAIN SHIPS: Sanegiyuu, Shinogiyuu +others WARNING! ⚠️ spoilers.? - angst, blood, sh, swearing .. illness... sensitive topics etc - cringe, canon and non canon ships! NOTE: IM NOT A DOCTOR!! please note some stuff in here is probably not accurate.

-On hiatus- Whenever Atsushi got bored in the orphanage he would go to the library to read books. It never really mattered what genre it was, he liked all of them. But his overall favorites were the mystery books. He liked to solve all the problems before the answer was revealed. It was fun for him. And then.. after a while.. He just knew. He knew every single answer. Atsushi stopped reading the mystery books, they weren't fun anymore. ---------------------------- Smart Atsushi AU I do not own any of the characters

Chuuya Nakahara got into an argument with his partner, Osamu Dazai. Now, he's riding his motorbike through Yokohama as a way to cool off. But when he swerves off of the road to avoid hitting two pedestrians and gets knocked out, he wakes up to see two Pro heroes in his hospital room. Chuuya then has to attend a prestigious school despite hardly being able to read, figure out how to get back to the Port Mafia, to apologise to Dazai, and why this old hobo wants to adopt him so badly. Basically me giving Chuuya a "normal" teen experience, and Dazai suffers for later angst <3 cross posted on ao3 on the user aoibb :3 - but it is on private to avoid access of ai and bots

While on duty, Pro hero Eraserhead (or better known as Aizawa to his friends and family) Runs into a scrawny teen in an alleyway. Aizawa's sense of justice forces him to take the boy under his wing, unaware of his true nature as the Port Mafia's own Demon Prodigy. This is from A03, so updates might be pretty inconsistent depending on if I remember to update this as well :,) This is a remastered version of This Boy's too Young to be Singing the Blues, which is a fic I worked on that I have now abandoned to rewrite.
