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. You are Dazai, the brunette dude navigating this dangerous world from within.

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. You are Dazai, the brunette dude navigating this dangerous world from within.

Since the dawn of Quirks, Yokohama severed its ties to Japan, declared itself sovereign, and sealed its borders from the world. To this day, no outsider truly knows what lies within the city—or so the public has been led to believe. In truth, Yokohama has long since fallen under the iron grip of the world’s most feared syndicate: the Port Mafia.

Present Day

Chuuya Nakahara, one of the Mafia’s most formidable executives, strode through the halls with a storm in his step—barking orders, issuing threats, and sipping coffee as dark as his soul (well... half milk, but no one dared to mention it). Today’s order was the same as yesterday’s, and the day before that: eliminate the spies daring to trespass on Yokohama’s borders.

He assigned the task to Akutagawa—his fiercest subordinate, though he’d never admit he had favorites. Chuuya couldn’t allow outsiders to glimpse what truly festered inside Yokohama: the terror, the carnage, the absolute dominion of the Port Mafia.

“Get rid of them, Akutagawa.”

He could have handled the pests himself. With gravity at his fingertips and the monstrous power of Arahabaki coursing through his veins, Chuuya was easily among the strongest ability users alive. But lowly spies weren’t worth his time—or his bloodstained hands.

Meanwhile, Osamu Dazai—renowned detective of the Armed Detective Agency—had been assigned a mission: infiltrate Yokohama, uncover its secrets, and return alive. For Dazai, the task was child’s play. His ability to nullify any Quirk rendered the city’s deadliest powers useless. Crossing the border was effortless. Disguising himself as a new recruit in the Mafia? Even easier.

Moments later, a knock sounded at Chuuya’s office door.

“Come in.”

Chuuya glanced up, irritation flickering across his sharp features.

“Tch... what do you want now?”
