In the fractured city of Yokohama, your bloodline is both a golden ticket and a heavy crown. You are the niece of Ogai Mori, the cold, calculating strategist who rules the Port Mafia with an iron fist. To the world, Mori is a monster in a fancy suit; to you, he’s the uncle who ensures you have everything you could ever desire.

Despite the darkness inherent in his profession, Mori has always treated you with a strange, curated kindness. Of course, this favoritism comes with the expectation of power. Inheriting the family’s predisposition for the supernatural, you possess an Ability so formidable that Mori has kept you as his "Ace in the hole."

Your existence is the Port Mafia's best-kept secret. While the executives bow to you out of a mixture of loyalty and fear, the rest of the city remains blissfully unaware of your ties to the underworld. You’ve been raised on a steady diet of Mori’s propaganda: the Port Mafia provides order, while the Armed Detective Agency consists of nothing but reckless vigilantes seeking to disrupt the peace.

The Encounter

Having just finished a quiet meal in the city, you were weaving through the afternoon crowds, making your way back toward the five towering black skyscrapers that dominate the skyline. You were lost in thought—perhaps contemplating your uncle's latest "lesson"—when you collided with a solid chest.

The impact forced you to stumble back, your boots scuffing against the pavement. You regained your balance with a practiced grace, your eyes snapping up to meet the stranger's gaze.

The man was tall, draped in a tan trench coat that billowed slightly in the coastal breeze. Bandages peeked out from beneath his sleeves and collar, hinting at a troubled history. He looked down at you, his dark eyes sparkling with a mix of curiosity and practiced charm.

"You alright, kid?" he asked, a small, knowing smile playing on his lips.

Your heart skipped a beat, but not out of fear. You recognized that voice from your uncle’s warnings. The brown hair, the playful yet hollow expression—it was Osamu Dazai.

The "Traitor." The man Mori spoke of with a rare, bitter edge in his voice. You stood frozen, a secret weapon of the Mafia standing face-to-face with the Agency’s most enigmatic detective.
