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.

Aizawa is unable to go straight back to teaching due to his injuries, so UA needs a substitute. Nezu contacts an old friend named Fukuzawa, asking for the nullification ability user he talked about. Fukuzawa agrees after being told the whole story, knowing that this League Of Villains will prove troublesome. Dazai goes to teach at UA as the president tells him to, and he realizes that the people outside Yokohama are stupider than he thought.

Dazai is the Port Mafia boss, and Chuuya is his right-hand man. They fight all the time, yet Chuuya is extremely protective of Dazai, his boss, even though he claims to hate him with all his heart. WARNING: sex, bdsm, toxicity

Never lie to Dazai.

824, 880 people died that day but history won't remember a single one. Dazai, the strongest and most fearful executive ever to be known in the Port Mafia, who lived in the belly and shadows of the beast of Yokohama was watching as the city he loved so much fell apart around him. He watched as building split down the middle and fell on to the street cracking the streets and killing innocent by standers. Dazai saw everything he loved so dearly being ripped from him second by second. "Dazai watch out!" Odasaku said as he ran and jumped grabbing Dazai and they both tumbled to the ground as a building fell over beside them. "Shit that was close." Odasaku said sighing. But they weren't catching a break as another building fell over. Dazai? Kouyou-nee? Dazai said as he spoke back into his ear piece. Don't let that child stray too far away. He has destroyed enough of Yokohama. Hurry and cancel out his ability.

Since the beginning of Quirks, Yokohama has announced independence from Japan and closed itself from the rest of the world. To this day and age, no one knows what lies within the city of Yokohama-or that was what the public was made to believe. In reality, Yokohama has long fallen into the control of the world's largest criminal organization known as the Port Mafia. Follow Class 1-A as their principal organized a field trip to Yokohama! In their short trip there, they must change their perspectives and learn exactly what it means to be justice and what it means to be villains.

As a compensation of all the torture I made Dazai go through, here you go my sweetheart, your well desired book~ @LzeroS You better forgive me and give me more love and attention, because yes~ <3 And of course I haven't forgotten about your request as well~ @TophBeifong44 And, for all of my dearest readers, this book will be updated rather slowly as I have other matters to attend to in real life so apologies 🙇‍♀️ Thank you for all the support!!! Disclaimer: The characters and artworks aren't mine, but the plot is~

Mori, being the leader of port mafia he is, decided to invest in hero society. Of course that was just a front for getting more information. With that he invited the most known hero academia to Yokohama. And who else would he entrust these naive heroes to then his most trusted subordinate, Dazai.

Yokahoma has always been strange. The security around its borders were strict, allowing very little to no people to enter. The dawn of quirks only increased security measures around the border. However due to a little inconvenience, the port mafia boss, Mori Ougai, has no choice other than ask help from the so called 'heroes' with the one condition of sending his 2 young executives, Dazai Osamu and Nakahara Chuuya, to the prestigious hero school UA. How could he decline such an offer? This was a little too perfect. How will their stay turn out? This is the same fanfic from ao3 "Too Perfect?" which was written by me. I wanted this fanfic to be accessible to more people, so I decided 'why not post it on Wattpad as well!' So here I am :) however, I'd still recommend reading on AO3 since updating on Wattpad is not my top priority! (Also there has been a lot of technical difficulties regarding Wattpad but I'll try and fix it) I hope you enjoy reading!

chuuya urgently needs money and decides to find himself a sugar daddy. getting a temporary one, means no feelings attached, right?
