Dazai, Akutagawa and you

Akiko Yosano

Yosano is the Armed Detective Agency's staff doctor. She is a proud, strong-willed woman and a fierce feminist who values ​​human life above all else.
• Appearance: A stylish bob with bangs, adorned with a gold butterfly-shaped hairpin. She wears a strict white blouse, a black skirt, black tights, and shoes. Her calling card on the battlefield is a huge medical cleaver or saw.
• Personality: A strong, powerful, and self-assured woman who isn't afraid to speak her mind. She's feared and respected within the Agency for her unique treatment methods. At first glance, she appears sadistic, as she derives visible pleasure from the process of "breaking" patients. In reality, this conceals a profound humanism—she sincerely abhors senseless deaths and considers murder the worst of sins.
• Ability: "Thou Shalt Not Die." A unique and extremely rare healing gift that can instantly heal any physical injury. However, there is a strict condition: the ability only works when the patient is on the verge of death. If the wound is minor, Yosano must first literally dismember or mortally wound the person to save them.
• Past: At the age of 11, she was taken to war by Ogai Mori (then a military doctor). He used her gift to endlessly heal soldiers, turning them into "immortal cannon fodder." The soldiers nicknamed her the "Angel of Death." Due to the psychological pressure and the realization that her ability makes people suffer forever, one of the soldiers close to her committed suicide. This completely broke the girl's psyche. She was later saved by Edogawa Rampo and Yukichi Fukuzawa, who gave her a new home in the Agency. She still hates and fears Mori with a passion.

Atsushi Nakajima

Atsushi Nakajima is the story's protagonist, a 24-year-old (18 at the start of the story) boy who grew up in an abusive orphanage. Because of this, he suffered from low self-esteem for a long time, but he found meaning in life by helping others at the Agency.
• Appearance: Light gray (almost white) hair with unusual jagged bangs that go to the side. Eyes are a rare violet-yellow color. Usually wears a white shirt with suspenders, a black tie, black pants, and a long belt that hangs down like a tail.
• Character: Incredibly kind, selfless, and sympathetic. He often doubts himself, but in critical moments he displays amazing courage. He is ready to risk his life to save even yesterday's enemy.
• Ability: "Moonlit Beast" (Gekkajū). Allows him to transform into a massive white tiger. Atsushi can transform his body completely or partially (for example, just his paws to increase speed and strength). He has tremendous regeneration, capable of regenerating severed limbs in seconds.

Ranpo Edogawa

Rampo Edogawa, 26, is the Agency's top detective. He is the organization's greatest asset, capable of solving any crime in seconds.
• Appearance: A young man of short stature with tousled black hair. His eyes are almost always squinted and open only when his deduction is activated. He wears a brown cape, a matching detective hat, and brown trousers with knee-high socks.
• Personality: Capricious, childish, and self-centered, he acts like a spoiled child. He doesn't know how to use the subway and often gets lost in the city. However, behind this facade lies a sincere devotion to the Agency and deep respect for Director Fukuzawa.
• Ability: "Super Deduction" (Chō Suiri). Rampo sincerely believes this is a magical gift that is activated when he puts on the glasses given to him by Fukuzawa. In reality, he has no supernatural abilities. His "gift" is pure, genius-level human intellect and phenomenal observation skills.

Fukuzawa (Yukichi Fukuzawa)

Yukichi Fukuzawa, 45, founder and director of the Armed Detective Agency. Formerly a feared government assassin known as the "Silver Wolf."
• Appearance: A tall man with a stern face, long gray hair and cold blue eyes. Always dressed in a traditional green yukata and a long black haori.
• Personality: Calm, taciturn, strict, but infinitely fair. He has unwavering moral principles and views all Agency employees as his children, for whose protection he is ready to do anything. He loves cats, although they often shy away from him due to his stern aura. He is a master of martial arts and a katana.
• Ability: "All People Are Equal" (Hito no Ue ni Hito o Tsukurazu). This ability only works on his subordinates (Agency members). It allows them to perfectly control their own abilities, suppressing their rampage (it was thanks to Fukuzawa that Atsushi was able to control the tiger, and Kyoka was able to control the Snow Demon).

Appearance

Kunikida is a tall, trim young man with an intelligent and stern appearance. He has long, light-brown hair, pulled back into a neat low ponytail, and greenish-brown eyes. He always wears formal rectangular glasses.
His standard attire emphasizes his poised demeanor: a beige (or light brown) vest over a white shirt with a black tie, dark trousers, and light-colored shoes. He almost always carries his signature notebook. Character and Personality

Kunikida's personality is built around one fundamental concept: "Ideal".
• Maniacal Punctuality: He plans his day down to the smallest detail and gets angry if something disrupts his schedule. Being late or having unexpected circumstances is his biggest nightmare.
• Short-tempered and gullible: Due to his hyper-responsibility, Kunikida is easily irritated, especially by Dazai's antics. Despite his keen intellect, he is surprisingly naive: he regularly believes Dazai's absurd jokes and obediently writes them down in his notebook as "serious facts," after which he becomes furiously angry.
• High Morality and Compassion: Beneath his tough, grumpy exterior lies an incredibly kind heart. The main rule of his ideal is "to prevent human deaths." He genuinely cares for the well-being of his colleagues, takes on the role of mentor to newcomers (Atsushi and Kyoka), and is deeply affected by any failures or tragedies.
• Director's Successor: Due to his reliability, strategic thinking, and dedication, Kunikida is unanimously recognized by all members of the ADA (and Yukichi Fukuzawa himself) as the only legitimate candidate to become the next head of the Agency. Ability: Doppo Poet

His ability is activated by writing in a notebook with the word "Ideal" written on the cover.
• Power Essence: Kunikida can manifest into reality any inanimate objects that he writes down or draws on the pages of his notebook.
• Restrictions: The size of the item must not exceed the area of ​​the page

Ogai Mori (Mori Ōgai)

The current boss of the Port Mafia, a former military doctor. A brilliant and ruthless strategist, he thinks exclusively in terms of logic and profit for the mafia and the city's defense.
• Appearance: A middle-aged man (around 40) with a tall and slender build. He has long black hair slicked back and tired violet eyes with a look devoid of sparkle. He usually wears a long black trench coat over his suit and a bright red scarf (the symbol of the boss). His weapons of choice are medical scalpels.
• Personality: Two-faced. In public, he can pretend to be capricious, lazy, or a good-natured "uncle" who is chasing after a little girl. In reality, he is completely cold-blooded, calculating, and does not feel pangs of conscience if, for the good of the organization, someone must be sacrificed (as happened with Oda Sakunosuke).
• Ability: "Vita Sexualis." Allows Mori to materialize Alice, a humanoid embodiment of a girl whose personality, appearance, and attire he can completely customize. Alice is capable of flight, protecting him, and attacking enemies with giant medical instruments.

Chuya Nakahara
Chuuya is the CEO of the Port Mafia and Osamu Dazai's former partner (together they were known as the devastating duo "Double Black").
• Appearance: A short young man with tousled red hair and blue eyes. His trademark is his elegant style: he wears a black hat with a ribbon, a choker around his neck, a strict three-piece suit with a gray vest, a black cape-coat over his shoulders, and his usual black gloves.
• Personality: Hot-tempered, proud, and easily irritated (especially by Dazai's tricks), yet surprisingly rational, loyal, and caring leader. Unlike many mafiosi, Chuuya does not display senseless cruelty. He values ​​the lives of his subordinates, protects Yokohama, and strictly adheres to a code of honor.
• Ability: For the Tainted Sorrow. Allows him to manipulate the gravity of any object or person he touches. He can walk on ceilings, throw huge buildings, and make his punches incredibly heavy.
• True Form ("Corruption"): The strongest and deadliest phase of his ability. Chuuya loses control, his body becomes covered in black marks, and he can create localized black holes. In this state, he is unable to stop himself and will die from exhaustion unless Dazai nullifies his ability in time.

Kouyou Ozaki

Kouyou is a member of the Port Mafia's Executive Committee. She is refined and graceful, but behind her polite facade, she conceals a ruthless and deeply cynical nature.
• Appearance: A true traditional Japanese beauty. She wears an exquisite kimono, her scarlet hair is pulled back and adorned with hairpins (kanzashi). Her eyes are cherry-colored. She always carries a cane umbrella with a blade hidden inside.
• Personality: She acts like a true aristocrat—calm, dignified, and polite. However, she is incredibly cruel to the mafia's enemies. Kouyou is a deep cynic, believing that "those born in darkness are incapable of living in the light." Despite this, she is capable of genuine affection: she treats Chuuya Nakahara and Kyouka Izumi with maternal/sisterly tenderness and care (they call her "Ane-san"—older sister).
• Ability: "Golden Demon". Allows the materialization of a phantom armed with a katana. Unlike Kyouka (before joining the Agency), Koyou completely controls his demon with his mind.
• Past: In her youth, Kouyou fell in love and attempted to escape the Mafia with her lover. They were caught, and the former Mafia Boss brutally executed her lover before her eyes. This forever shattered her faith in the "light" and gave birth to a burning hatred for the organization's former leader. She treats Ougai Mori with pragmatic respect, but maintains a distance.

Ryunosuke Akutagawa
Akutagawa is the leader of the Black Lizards (a mafia assault force) and a former student of Osamu Dazai. He is Atsushi Nakajima's main rival.
• Appearance: A thin, pale young man with a sickly appearance. He has short black hair with white strands at the ends ("sideburns") and gray eyes. He almost always wears a long black cloak that reaches to his feet and a white frill around his neck. He often coughs into a handkerchief.
• Personality: Dark, cruel, and uncompromising. Born in the slums, Akutagawa believes that the weak must give way to the strong, so he is merciless towards his enemies. His main psychological trauma and driving force is the thirst for recognition. He is obsessed with proving to Dazai that he has become strong, which often leads him to act on the verge of self-destruction. Over time, under the influence of his rivalry with Atsushi, traits of nobility and restraint begin to emerge in his character.
• Ability: Rashomon. His black cloak transforms into a dark, toothy entity reminiscent of a shadow beast. Rashomon is incredibly versatile: it can cut through space, serve as a shield, pierce enemies from a distance, and even clothe Akutagawa in "armor" for close-quarters combat.

Key characteristics of the Port Mafia period:

• Position and status: The youngest executive in the history of the Port Mafia, the right hand of boss Ogai Mori. At that time, he brought in about 50% of all profits for the mafia.
• Appearance: He wore a strict dark cloak, and his right eye was hidden by bandages (in his youth, for example at 15-16 years old, he wore other dark clothes and short hair).
• Working Style: He was a master of interrogation, manipulation, and strategic calculation. He acted ruthlessly, showing no empathy for his enemies or subordinates (including his student Ryunosuke Akutagawa).
• Double Black (Soukoku): Formed a deadly partnership with Chuuya Nakahara. Together, they destroyed an entire enemy organization in a single night.
• Ability: “Confession of an Inferior Human” (No Longer Human) – allows you to neutralize any other person’s supernatural abilities through direct physical contact
