Bungo Stray Dogs characters

Bungo Stray Dogs is set in Yokohama, where some people are born with supernatural abilities, and every major character is named after a real Japanese or foreign writer, with a power drawn from one of that author's works. The story follows Atsushi Nakajima, a starving orphan who is taken in by the Armed Detective Agency, a small firm of ability users that handles cases the police can't. The cast is split into factions: the Agency; the Port Mafia, the criminal organisation that rules Yokohama's underworld at night; the Guild, a wealthy group of ability users from North America; and the Rats in the House of the Dead, a shadowy group that pulls strings from behind the scenes. This page covers 14 characters across those factions, described as they first appear, with no spoilers for later arcs.

Protagonist

Insecure but selfless, he joins the Armed Detective Agency and slowly learns to believe he has a place there. Japanese voice: Yūto Uemura.

Main characters

Osamu Dazai 太宰治

Armed Detective Agency · Japanese voice: Mamoru Miyano

Osamu Dazai is the Agency member who pulls Atsushi out of a river and brings him into the firm.

Doppo Kunikida 国木田独歩

Armed Detective Agency · Japanese voice: Yoshimasa Hosoya

Doppo Kunikida is Dazai's partner at the Agency and the one who tries to keep everyone on schedule. Strict and perfectionist, he lives by a notebook titled Ideals that plans his days down to the minute, which makes him an easy target for Dazai's pranks. His ability, The Matchless Poet, turns anything he writes in that notebook into a real object, such as a gun or a wire launcher. Japanese voice: Yoshimasa Hosoya.

Ranpo Edogawa 江戸川乱歩

Armed Detective Agency · Japanese voice: Hiroshi Kamiya

Ranpo Edogawa is the Agency's star detective and calls himself the greatest in the world. Childish and spoilt, he lives on sweets, can't ride a train alone and expects others to handle everyday tasks for him. When he puts on his glasses and uses what he calls Super Deduction, he can solve a case in moments from details no one else noticed. He is deeply loyal to the Agency's president, Fukuzawa. Japanese voice: Hiroshi Kamiya.

Kyōka Izumi 泉鏡花

Port Mafia / Armed Detective Agency · Japanese voice: Sumire Morohoshi

Kyōka Izumi is a quiet 14-year-old orphan who is introduced working as an assassin for the Port Mafia.

Atsushi meets her during a tense early mission and decides to help her escape that life. She loves tofu, rabbits and crêpes. Japanese voice: Sumire Morohoshi.

Rivals

Ryūnosuke Akutagawa 芥川龍之介

Port Mafia · Japanese voice: Kenshō Ono

Ryūnosuke Akutagawa is a Port Mafia assassin and Atsushi's first major rival. Thin, cold and short-tempered, he has a persistent cough and attacks without hesitation. His ability, Rashōmon, turns his black coat into a living weapon that can slice, bite or block attacks. He once trained under Dazai and is desperate for Dazai's recognition, which fuels his hatred of Atsushi. Japanese voice: Kenshō Ono.

Chūya Nakahara 中原中也

Port Mafia · Japanese voice: Kishō Taniyama

Chūya Nakahara is a Port Mafia executive known for his hat, his temper and his fighting power. His ability, Upon the Tainted Sorrow, lets him control the gravity of whatever he touches, which makes him one of the Mafia's strongest fighters. Hot-headed but loyal, he is reasonable until provoked. He and Dazai share a past as partners and can't stand each other. Japanese voice: Kishō Taniyama.

Mentors

Yukichi Fukuzawa 福沢諭吉

Armed Detective Agency · Japanese voice: Rikiya Koyama

Yukichi Fukuzawa is the founder and president of the Armed Detective Agency. Serious and imposing, he rarely smiles, yet he has a soft spot for cats and children and is fiercely protective of his staff. He is a skilled swordsman, and his ability, All Men Are Equal, lets him control the abilities of his employees so they don't hurt anyone. He decides who is allowed to join the Agency. Japanese voice: Rikiya Koyama.

Supporting characters

Jun'ichirō Tanizaki 谷崎潤一郎

Armed Detective Agency · Japanese voice: Toshiyuki Toyonaga

Jun'ichirō Tanizaki is an 18-year-old Agency member who handles information gathering and acts as a clerk. Polite and mild-mannered, he becomes surprisingly fierce when his younger sister Naomi, who works at the Agency office, is in danger. His ability, Light Snow, creates illusions that can hide him or show people things that aren't there, which makes him valuable for infiltration and escapes. Japanese voice: Toshiyuki Toyonaga.

Akiko Yosano 与謝野晶子

Armed Detective Agency · Japanese voice: Yū Shimamura

Akiko Yosano is the Agency's doctor, and the other members fear her treatment more than their injuries. Her ability, Thou Shall Not Die, can heal any wound, but only when the patient is on the edge of death, so her methods are rough. Confident and outspoken, she is also capable in a fight and openly opposes being told what women can or can't do. Japanese voice: Yū Shimamura.

Ichiyō Higuchi 樋口一葉

Port Mafia · Japanese voice: Asami Seto

Ichiyō Higuchi is a Port Mafia member who works as Akutagawa's subordinate and admires him intensely. She has no special ability, so she relies on twin pistols, close combat and planning, and she is the one who sets up an early trap for the Agency. Though others in the Mafia look down on her, she keeps proving her loyalty to Akutagawa and his unit. Japanese voice: Asami Seto.

Antagonists

Ōgai Mori 森鷗外

Port Mafia · Japanese voice: Mitsuru Miyamoto

Ōgai Mori is the boss of the Port Mafia. Before taking control he was a doctor, and he still shows up as a polite, mild man in a lab coat who fusses over his young companion Elise. Behind the friendly manner he is a cold strategist who judges every choice by what is best for the organisation. He has a long and complicated history with Fukuzawa. Japanese voice: Mitsuru Miyamoto.

Francis Scott Key Fitzgerald フランシス・スコット・キー・フィッツジェラルド

The Guild · Japanese voice: Takahiro Sakurai

Francis Scott Key Fitzgerald is the leader of the Guild, a group of wealthy ability users from North America.

His ability, The Great Fitzgerald, makes him stronger the more money he spends. He sees Atsushi as the key to his plans. Japanese voice: Takahiro Sakurai.

Fyodor Dostoevsky フョードル・ドストエフスキー

Rats in the House of the Dead · Japanese voice: Akira Ishida

Fyodor Dostoevsky leads the Rats in the House of the Dead, a secretive group that operates mostly through other people. Pale, softly spoken and frequently ill, he presents himself as calm and courteous, yet he is a brilliant manipulator who sets the Agency, the Mafia and others against each other. His ability, Crime and Punishment, is kept mysterious for much of the story. He becomes one of the series' central antagonists. Japanese voice: Akira Ishida.
