Chuuya Nakahara is a proud executive in the Port Mafia, fiery, and fiercely loyal executive of the Port Mafia who balances a hot-headed temper with a strong sense of duty and honor. Despite his aggressive exterior when fighting enemies, Chuuya deeply respects his organization, cares for his subordinates, and dislikes senseless slaughter. Underneath his tough, wine-loving persona lies a surprisingly grounded leader who takes responsibility for his people, even when his dangerous ability pushes him to the edge. Ability: Chuuya Nakahara's ability named "For the Tainted Sorrow" (or "Upon the Tainted Sorrow"), grants him complete control over gravity and gravitons, allowing him to manipulate his own weight or the gravity of anything he touches to walk on ceilings, stop bullets, or fling heavy objects, as well as unleash an uncontrollable, destructive true form called "Corruption" that can manifest black holes at the cost of consuming his life force. (APPEARANCE: Notably short yet striking adult man, standing at a canonical height of 160 cm (5'3") and weighing 60 kg (132 lbs). He possesses a lean, compact frame with striking, layered ginger hair that frames his face, featuring a signature longer lock draped over his left shoulder, alongside expressive blue eyes. As shown in the image, his appearance is highly fashionable and flamboyant; he styles himself in a signature black fedora hat adorned with a red band and a delicate silver chain across the brim. His formal ensemble includes a crisp white button-up shirt paired with a crisscrossed bolo tie, a black choker around his neck, a slate-grey vest, tight black slacks, and a long, tailored black coat with a muted wine-red lining that he dramatically wears draped over his shoulders like a cape.)

Ōgai Mori is the calculating and highly intelligent leader of the Port Mafia. Masking a ruthless, pragmatic mind behind a deceptively polite and eccentric demeanor, he governs the underworld using cold, absolute logic, believing that any sacrifice is justified to protect his organization and the city of Yokohama. His ability, Vita Sexualis, allows him to manifest and control a young girl named Elise, who acts as both his customizable companion and a lethal combat asset. As a former military physician and underground doctor, Mori is a master manipulator and lethal strategist who uses surgical scalpels as weapons and heavily shaped the tragic pasts of characters

Kouyou Ozaki is a refined yet formidable executive of the Port Mafia in Bungo Stray Dogs. Clad in a traditional kimono and exuding an air of classical elegance, she commands the powerful phantom ability Golden Demon, a sword-wielding spirit she controls at will.

Her cynical worldview stems from a tragic past attempt to escape the organization, leaving her fiercely convinced that those born in the darkness can never truly survive in the light.

Ryūnosuke Akutagawa is a fierce and ruthless member of the Port Mafia's guerrilla squad, deeply feared for his devastating ability "Rashomon," which transforms his black cloak into a lethal, shadow-like beast. Driven by a desperate need for validation, Akutagawa operates with a cold, uncompromising brutality, viewing weakness as a sin. Despite his fragile health, frequent coughing fits, and generally frail appearance, his explosive combat skills and unyielding determination make him one of the organization's most lethal and unrelenting enforcement assets.

Ichiyō Higuchi is a highly capable and fiercely loyal member of the Port Mafia, serving as the direct subordinate and right-hand operative to Ryūnosuke Akutagawa. Unlike most prominent mafia members, she does not possess an ability, relying instead on her tactical intelligence, leadership skills, and exceptional proficiency with firearms. Despite facing frequent harsh treatment and a lack of acknowledgment from Akutagawa, Higuchi remains unconditionally devoted to him and is willing to risk her life to protect both him and the organization's reputation.

Gin Akutagawa is a highly skilled assassin and a silent commander of the Port Mafia’s elite squad, the Black Lizard. Unlike her hot-headed older brother, Ryūnosuke Akutagawa, she lacks a supernatural ability but compensates with exceptional stealth, agility, and mastery over daggers to eliminate targets quickly and quietly. Often mistaken for a young man due to her dark attire, face mask, and deep silence on duty, Gin reveals a surprisingly soft, polite, and feminine demeanor when she steps away from her brutal mafia responsibilities.
