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.)

Sasuke's Rinnegan takes him to the world of BNHA, shenanigans and Sasuke being thoroughly unimpressed with the hero world ensue. I do not own Naruto or BNHA, both belong to their respective owners, this is for entertainment purposes only. Any and all art I use isn't mine. I can't draw. !! IMPORTANT !!: As of May 20th, all updates for this fic will continue on AO3 under my account there, MTDSOW for reasons listed in the final chapter.

[UNDER EDITING] When Jouno Todoroki was born both quirkless and blind, his father immediately dismissed him as a failure. But over the years of being ignored by everyone but his mother, he learned how to heal. Experimenting on himself to create the ultimate medical serum for his future brothers and sisters that he knows will get hurt.

Art is most definitely not mine unless I say so (I'm looking for the original posters) Kinich gets dropped off in MHA with three saurian whelps after doing a favor for Kachina and Mualani. The babies have imprinted him as their mother but Kinich has no idea who is the father. However, Ajaw seems to know but refuses to tell him. Why? ------------------ @TheDumbBirdinYard is my co-author and wrote the fight scenes and Christmas special :]

What if instead of a bell Dream manages to wish for a way out of the prison? What if that way out was a portal leading to a new dimension full of heroes and villains? What if Dream and Technoblade were essentially gods among men in this world? An anarchist and a self proclaimed puppeteer could only end up as villains. Especially when the government was as oppressive as this one. "Who are you, villains?!" "You may call me, Blade." "And I'm Nightmare." ____________________________________________ Welcome to my newest story! As usual updates are when motivation hits to ensure quality work. A small disclaimer, I am taking some serious creative liberty on the MHA portion of this story. (Mostly because I stopped watching MHA after the Provisional Hero Licence exam) There will be no ships, between the MCYT. MHA ships will be limited to the Dad for One headcanon. Art is not mine. With that, Enjoy!

In a world that exalts Heroes and worships Quirks, the port city of Yokohama stands tall as a feared anomaly. Isolated by a mysterious mist and governed by its own laws, the outside world knows it as a "Criminal Paradise" ruled by the Port Mafia. However, the reality is far more complex; the city is the focal point of reality itself, maintained by a fragile balance between three organizations through the Tripartite system. Following the USJ incident that shook UA Academy, a secret agreement brings two figures from Yokohama into the heart of Hero society: Dazai Osamu and Edogawa Ranpo. They come not to save the world as heroes, but as observers and guardians of humanity's greatest secret. Yet, as Dazai attempts to adapt to the naive idealism of the Class 1-A students, an old shadow begins to creep through the chaos sown by the League of Villains. Behind the curtain of a conspiracy involving the symbols of peace and evil, someone is reweaving the threads of destruction that were once severed-someone who believes the best way to save the world is to erase all power-users from the face of the earth. Dazai realizes sooner than anyone that the echoes of the rat's laughter have not truly faded, and the chessboard he left behind in Yokohama is now expanding across the entirety of Japan. --- ### **{WARNING!}** • Typographical errors • Grammatical errors • Punctuation errors • Violence and blood • Bad words • Suicide attempt • Bad English because it's not my mother tongue • Profanity • Heavy conflict • Alternate universe (AU) and world-building • Neutral alignment • Update schedule depends on mood • Any similarities to other works are unintentional, as the concept of Yokohama as an isolated city is a common trope.

Yokohama has been the talk of Japan since Quirks first appeared. It was the only city in the world that Quirks did not appear in, due to a barrier protecting the city. | | | | (A lot of things will be changed, you will understand more as you read. But I will give a brief summary of changes: -The abuse Akutagawa went through with Dazai was minor and resembled actual training. HE WAS A GOOD MENTOR in other words. -Mori isn't Pedoph!l!c in this and he actually treated the kids in the PM as if they were his kids. He was only harsh in words when he needed to be, like a strict parent. -Also wanna say here that none of the relationships are toxic in anyway and they are actually relatively healthy. -Also wanna mention that while the PM members were treated better, the PM is still a "criminal" organization and still commits crimes for the sake of Yokohama *most of the time*. -Just saying this here: the DOA will not be making appearances but they will be mentioned. The hunting dogs will be mentioned as well, but start to make appearances at ch.27. -There are more changes but these are just the main ones!.) Now some warnings: -Gore Scenes Described -Violence -Mentioned Abuse -MLM -WLW -Might have *some* NSFW content -BNHA characters might be a little naive *this is just how I choose to write them for this book* -Discussion of murder -You're fav character from BNHA might not be how you want. Some characters will be unbearable at times. This is due to how they views things as black and white. -This book will not have any BNHA ships explicitly stated. -In this book, Abilities are way stronger than Quirks, just warning. -MINETA Now Timelines: Bsd: no timeline but definitely *future* because of how things are. MHA: shortly after USJ, instead of the training camp arc, they go to Yokohama.

They were the Port Mafia's deadliest weapon-Soukoku, the fearsome Double Black. Two fifteen-year-old executives bound by blood, violence, and an obsession so complete it terrified everyone around them. When their boss attempts to sacrifice them for political gain, Chuuya Nakahara and Dazai Osamu make an impossible choice: kill him and escape over the Barrier into hero society. But leaving Yokohama doesn't mean leaving their past behind. Now trapped in UA High School, they must navigate a world of heroes who can never understand what they've survived. Chuuya's possessive protectiveness borders on violence-he'll destroy anyone who threatens Dazai. Dazai's suicidal tendencies and manipulative genius make him both brilliant and dangerous. Together, they're codependent, obsessive, and utterly devoted to each other above all else. As the Port Mafia hunts them and hero society demands they become something they're not, Chuuya and Dazai must decide: can two weapons forged in darkness learn to protect instead of destroy? Can their obsessive love become something more than survival? And when forced to choose between their past and their future, will they burn the world down to stay together? A tale of tactical genius, brutal efficiency, possessive devotion, and two boys who love each other enough to become monsters-or heroes-depending on who's asking. "You're mine. I'm yours. Everything else is negotiable." CONTENT WARNING: Violence, references to child abuse, suicidal ideation, murder, unhealthy codependency, possessive behavior, organized crime, trauma, mature themes.

Y/N L/N son of two small time villains. With his quirk idle transfiguration, he can change his body to his will using up energy in return. After his quirk gets an unforseen second awakening, he accidentally kills his parents. But with no evidence pointing towards an accident and a second awakening just like that happening highly unlikely. He is given two choices by the Hero commission.

Haku Yuki was supposed to die on a bridge. Instead he woke reborn into the Yukimura clan, heir to a quirk that lets him slip through mirrors and bend cold into blades. Bound by duty to an arranged alliance with Shoto Todoroki, Haku must learn to move like a weapon and think like a shield. At U.A. he trains under watchful teachers, weathers whispered rumors, and faces a world that prizes power over mercy. When the USJ attack shatters the classroom's safety, Haku's calm precision and Shoto's volatile strength collide with villainy and sacrifice. Between tea ceremonies at the estate and battles that demand everything, two heirs discover that protection can be taught, but courage must be chosen. Quiet, strategic, and dangerous in equal measure, Haku must decide whether to be the clan's perfect blade-or the kind of hero who refuses to vanish.
