PROFESSION Teacher (Formerly) Detective Internal Director

ORGANIZATION Shin-Tsuruya Institute (Formerly) ACA (Armed Detective Agency)

Doppo Kunikida (国木田 独歩, Kunikida Doppo) is a member of the Armed Detective Agency and Dazai Osamu's partner. Has the ability "Doppo Poetry".

Appearance:

Doppo is a tall young man of average build, with blond hair and grass-gray eyes. His bangs point to the right and his hairstyle is tied into a long ponytail, but still has spiky hair. He always wears glasses. His outfit consists of a beige vest over a long-sleeved black shirt, a red ribbon tied around his collar, beige pants, and plain brown boots.

Personality:

Doppo appears to be a very serious, but also slightly hot-tempered young man. Throughout his life he documents events in a notebook. Doesn't recognize anything other than his small notebook. Most likely, he is a perfectionist. As a member of the Armed Detective Agency, Kunikida takes his work very seriously and responsibly, as the agency's reputation is paramount to him. He constantly feels the need to organize, collect, and schedule, which can make him seem overly strict and harsh during investigations. He can also be considered practical out of guilt, as he almost decided to leave the kidnapped Atsushi because the boy's presence might affect the agency. Despite this, Doppo is nonetheless a trustworthy and loyal detective who is relied upon by many in the agency for his authoritative abilities and responsible nature. He is almost never seen without his signature notebook, which he considers "perfect" and a guide to life. He uses this function for several reasons such as data collection, planning and most importantly the environment for his ability, Doppo's Poetry. Portraying a calm and cautious front, Kunikida is also known for his irritated outbursts, which are primarily caused by his partner, Dazai, who constantly irritates him with his suicide attempts. He is also uncharacteristically naive and tends to easily believe Dazai's lies, which he later writes down in his notebook for later reference.

When Atsushi tried to guess the previous positions of the Agency members, it turned out that Doppo used to work as a mathematics teacher. In episodes 6 and 7, Dazai stole the "Ideal" and showed the standard of an ideal woman written by Kunikida, Atsushi Nakajima and Sasaki Nobuko, the girl they saved in episode 6. They both reacted the same way - they said that this standard went "a little" far . It’s a pity that the standard was never shown in either anime or manga, and it remains unknown to viewers. Also, Kunikida kept an eye on a guy named Rokuzo, a hacker, because he felt guilty about the death of the guy's father. The story is this: when Doppo found out and reported where the famous terrorist - the Azure King - was hiding, five detectives were sent there without much training, since the military and police were busy. The terrorist committed suicide as soon as he was almost caught by exploding a bomb. All the detectives also died. One of the dead detectives was Rokuzo's father, so Kunikida felt that he had to take care of the guy and try to become his dad.

Several days pass after defeating the Guild. After the incident with Katsura, Kunikida and Atsushi head to a certain hacker, where on the way Doppo tells his partner about him and shows the Moby Dick control panel, which was useless even after defeating Fitzgerald, and all because of the chip he points to Kunikida explains to the guy that at the last moment, someone hacked the controls of Moby Dick with the goal of bringing it down on Yokohama and destroying it. When Atsushi asks if they can trust this hacker, Kunikida replies that he has known him for over ten years and adds that he was once a member of the Armed Detective Agency at the same time approaching his home.

Atsushi and Kunikida arrives at Katai's apartment Kunikida and Atsushi visiting Katai. Finding themselves inside Katai's house, Kunikida angrily calls him, adding along the way that it is time for him to get out of this godforsaken place and restore order in the house, opening the door to the room, they watch the hacker himself, who is depressed in himself and is going to spend his whole life in his futon and die, to which Kunikida is not at all surprised. When Katai talks about how he envies even the ticks that live in his futon, Atsushi doubts him a little and asks Kunikida if this is the right person and if they have the wrong address, to which Doppo talks about Katai’s ability to control any electrical equipment in his field of vision and all this at a speed tens of times faster than usual. Kunikida even says that abilities This is enough to participate in the information war of military intelligence, but the hacker can concentrate only when his body and mind are most relaxed. Then, Katai reveals that he cannot use his abilities because he is in love.

Telling them about a meeting with a girl whom he immediately called his “Yamato Nadeshiko”, adding that his heart was won by a woman located at a distance of 500 meters, which slightly surprises Kunikida, who does not think that this can be considered a meeting. Continuing to talk, Kunikida makes tea and asks how many spoons of sugar to put Atsushi and then, when Katai shows a picture of this lady, he immediately amazes the others, since she is really very beautiful, and then again falls into depression due to the fact that she never will not meet her, but Atsushi promises the support of the Detective Agency, because if they find this girl, they will receive help from Katai. Kunikida is not very happy with this idea, but understands that they have no choice, while Katai personally asks them for help and gives them a letter, which they must give to the girl, so they leave to search.

Atsushi, Higuchi, and Kunikida looking for the woman Kunikida and Higuchi are looking for a girl. Then, they appear at the place where the mysterious lady last appeared. Atsushi asks Kunikida whether Katai has always been so shy, but why he still decided to take such a step, but Kunikida himself does not know. At this very time, Higuchi is looking for the same girl and notices these two, hiding, she knows that they do not need a conflict with the Agency, and at this time Kunikida is already standing behind the girl asking her what she needs from them. He says that if Higuchi decided to spy, she could have done it more carefully, since Atsushi's field of vision is very wide, so he easily noticed her, Atsushi himself is behind Kunikida. Higuchi asks to tell her about the girl, believing that she is their spy. Atsushi apologizes and says that they don't know her either, but they are also looking for her to give her a letter with a declaration of love, which makes Higuchi think that Atsushi has fallen in love.

Continuing to look for the girl with the three of them, Higuchi asks why guys only like such cuties, she advises Atsushi to change his image, but in response she hears the voice of Katai who says that he is not the one who confesses his love. Kunikida is surprised by Katai’s appearance on the street and then Tayama notices how that same girl is leaving the laundry, so he begins to chase her, which Higuchi does as well. Noticing Ichiyo, the mysterious girl runs away while Kunikida and Atsushi are just watching, and when they lead the girl into a dead end, they find out that this is Gin - who, in addition to being a cutie, is also Akutagawa’s sister, which makes Kunikida and Higuchi very surprised . Doppo and Nakajima then watch as Tayama gives the letter to Gin and receives a negative response.

File:The Truth About Gin.png The guys find out that Gin is Akutagawa's sister. Returning home, Katai again wraps himself in a futon and becomes depressed, but Kunikida only says that Tayama should have guessed that everything would end like this, to which Katai agrees, but tries to say something, but Kunikida interrupts him and calls him an idiot. Walking back to the office, Atsushi asks; what will happen to Katai now, Kunikida says that everything is in order and he will soon begin to study that symbol on the chip, adding that the hacker never had the courage to confess love at first sight, so he was sure that their task would come to a dead end, but he was very surprised that his friend went all-in, so he only adds that if he returned to the Armed Agency, things would become much calmer.[4]

Arc Cannibalism

Kunikida becomes afraid Kunikida is completely depressed in himself. After the capture of Dostoevsky, some time has passed, Kunikida is in prison, where he, in a bear costume, is visited by Ranpo, who promises to get him out, even if Kunikida himself is against this, he was accused of murdering the children of the fake Pushkin, which, strangely enough, is also part of the plan Dostoevsky, who framed Kunikida. Doppo is very depressed about this incident and he did not contradict the accusations, since he himself blames himself for this. When Kunikida asks why Ranpo is doing this? He replies that if he had seen through the demon's trap then, the girl (with the grenade) would not have died.[5]

Arc Death of the Celestials

Kunikida trains Atsushi (manga) Training with Atsushi. After his release from prison, Kunikida trains with Atsushi and easily knocks him to the floor, explaining that Atsushi simply attacks head-on, from which he can easily be defeated using a successful counterattack. When Atsushi asks what he should do, Doppo explains that Atsushi should not allow the power to completely take over his body, since previously he always lost when he allowed the tiger's power to take over him. Kunikida adds that the tiger is strong, but Atsushi is weak. He then looks at his watch and they both go to work.

A little later, Kunikida tells members of the Detective Agency about the appearance of mysterious and at the same time brutal murders, showing them photographs of the victims in and telling about their origin, thus describing the murders of the four victims. Then, when Ranpo guesses about the death of the celestials, Kunikida only adds that the appearance of these criminals foreshadows the five signs that precede their name: the death of the highest celestials, gods, in the teaching of Buddhism about the cycle of life and death, who, apparently, want to kill all those who occupy high positions in the government. Then, Atsushi guesses that if there are five signs and four murders, then the last murder should happen soon, to which Doppo agrees and adds that the fifth murder has not yet happened. At the same time, Director Fukuzawa orders to gather all his forces and stop the criminals, to which Ranpo refuses and quarrels with the director of the agency, and when Kunikida asks about the reasons, he explains his action with the last words of his friend, and then leaves the room and when Kunikida tries stop him, then Fukuzawa only stops the man.[6]

A few hours later, they receive a video message where Gogol talks about the fifth sign and when the video ends, Doppo looks at his watch and sees that they only have thirty minutes left to save the hostages. Then, he supervises Atsushi and tells about the place where he must get inside and turn off the timer, since the guy's speed is their key to success, and they themselves will arrive only in ten minutes, transmitting all this through the earpiece.

His ability, Doppo Poetry (独歩吟客, Doppo Ginkaku?), allows Kunikida to turn anything he sees into real objects, while retaining every function. For example, this way you can create a pistol, a suitable key or a stun gun. However, the item being recreated must not exceed the size of a notebook page.

Kunikida dropped out of college. Kunikida once worked part-time teaching algebra. Kunikida has a list of as many as 58 points for an ideal partner.

OCCUPATION Detective Mafia Executive (former)

AFFILIATION Armed Detective Agency Port Mafia (former)

Dazai is a young man with mildly wavy, short dark brown hair and narrow dark brown eyes. His bangs loosely frame his face, with several strands gathered near the center of his forehead. He is tall and slim, possessing a deceptively fragile appearance that contrasts sharply with his mental acuity and past brutality.

Dazai’s usual attire consists of a long sand-colored trench coat worn untied, a black vest layered over a light blue striped dress shirt, and a bolo tie secured with a turquoise pendant. He wears beige trousers and dark brown shoes. His body is almost entirely wrapped in bandages, leaving only his face, hands, and feet exposed. The bandages are implied to be remnants of both past injuries and repeated suicide attempts.

During his time in the Port Mafia, Dazai wore a long black trench coat that extended below his knees. At that time, his right eye was bandaged, and his right arm was kept in a sling—injuries implied to be self-inflicted or sustained during missions. He later regained full use of his arm. Following the Cannibalism arc, Dazai appears in a formal suit during the Armed Detective Agency’s celebration.

During the Yokohama Fog incident, he wore a white waistcoat over black long sleeves with a brown tie and white trousers, accompanied by a padded overcoat adorned with a lapel pin. After his arrest by the Hunting Dogs and subsequent transfer to Meursault Prison, Dazai is seen wearing plain white prison garments.

Dazai is an enigmatic individual whose true intentions remain concealed unless he chooses to reveal them. The person who came closest to understanding his true nature was Sakunosuke Oda. As acknowledged by Dazai himself, Oda recognized that Dazai would always exist within darkness, as there was little in the world capable of surpassing or fulfilling his intellect. Oda believed that no matter which side Dazai stood on—killing or saving—his loneliness would persist, and Dazai himself was aware of this truth.

While in the Port Mafia, Dazai cultivated a cold, calculating façade. His abilities and results earned him the title of the youngest executive in the Mafia’s history (歴代最年少幹部). Due to his extraordinary competence, Dazai was responsible for nearly half of the Mafia’s profits for at least two years. Ichiyō Higuchi once described Dazai’s blood as being “as dark as the Mafia itself.” Even after joining the Agency, this darkness remains evident; when Kyōka Izumi expressed guilt over having killed 35 people, Dazai remarked with chilling indifference that such a number was insignificant.

A saying within the Mafia stated: “The greatest misfortune for Dazai’s enemies is that they are Dazai’s enemies.” He was widely considered to be someone “born for the Mafia.” Dazai excelled at long-term strategic planning, psychological warfare, and manipulation. He successfully orchestrated the downfall of Mimic, a group of trained soldiers, by deliberately luring them into carefully prepared traps. His interrogations were particularly feared; even individuals who resisted Kōyō Ozaki’s torture squad often broke under Dazai’s words alone.

Dazai originally joined the Mafia to immerse himself in death, violence, and human desire, believing that witnessing humanity at its worst might reveal a reason to live. Following Oda’s death and his final request for Dazai to “save people,” Dazai defected from the Mafia and disappeared underground. He later acknowledged that people can change and that potential can surface over time—an idea that applies to himself as well.

Within the Armed Detective Agency, Dazai is frequently labeled lazy, with Doppo Kunikida constantly reprimanding him for slacking off. Despite this façade, Dazai consistently demonstrates exceptional insight and deductive ability. He was able to uncover the truth behind Atsushi Nakajima’s situation almost immediately, deducing that Atsushi himself was the tiger. Regardless of danger, Dazai maintains absolute composure, even in scenarios he deliberately engineers.

Dazai is highly theatrical and treats most situations as jokes, rarely taking credit for his own meticulously crafted plans. He enjoys teasing others, particularly when it provokes a reaction. His obsession with suicide is often portrayed comedically; however, his attempts typically fail or are abandoned if pain is involved.

Dazai openly expresses a desire to commit double suicide with a beautiful woman. While he claims to like all types of women, he appears drawn to those who would agree to die alongside him. Kunikida once described him as a menace to women, and Chūya Nakahara once threatened to leak Dazai’s address to every woman he had made cry—a threat Dazai urgently asked him not to carry out. On one occasion, a woman obsessed with Dazai even attempted to bomb him.

Beneath the humor lies a profound existential emptiness. Even as a teenager, Dazai questioned the value of life. His immersion in bloodshed was an attempt to fill that void, but Oda’s death ultimately redirected him. Though good and evil hold little intrinsic meaning to Dazai, he understands that choosing the side that saves people may allow him to become marginally better.

In the past, Dazai’s suicidal tendencies were far more serious. He described death as liberation from an “oxidizing world,” yet found himself unable to die despite repeated attempts. During this period, he was exceptionally cruel and methodical, capturing enemies alive for torture and brutally abusing his subordinate Ryūnosuke Akutagawa in order to force his growth.

In the present, Dazai retains his darker traits beneath a lighter exterior. He continues to execute long-term strategies without informing his allies until the decisive moment. He is willing to participate in elaborate charades if it serves his goals, as demonstrated during his Agency entrance exam. He does not hesitate to employ underhanded tactics, such as sabotaging Ango Sakaguchi’s car airbag to force his cooperation.

Despite his methods, Dazai genuinely cares for his comrades, particularly Atsushi Nakajima, in whom he sees immense potential. He has assumed a guiding role within the Agency and even orchestrated cooperation between Atsushi and Akutagawa as a modern counterpart to Twin Dark, anticipating greater threats to Yokohama.

Main article: No Longer Human

No Longer Human (人間失格, Ningen Shikkaku) allows Dazai to nullify any ability upon physical contact. The ability is always active and does not require conscious activation. Any ability that touches Dazai—directly or indirectly—is instantly nullified, even if he is restrained.

Skills

Intelligence: Dazai’s intelligence is his greatest asset. Ōgai Mori regarded him as his most capable subordinate and future right-hand man. Within the Agency, Dazai is recognized as one of its two greatest minds alongside Ranpo Edogawa. He is capable of matching Fyodor Dostoevsky in complex psychological warfare, and even Ranpo acknowledges Dazai as an enigma. Dazai excels at predicting outcomes and manipulating probabilities to his advantage.

Negotiation Skills: Dazai is a master persuader, capable of manipulating allies and enemies alike. He negotiated Kyōka’s capture and eventual protection, convinced Francis Scott Key Fitzgerald to cooperate against Fyodor, and maneuvered Akutagawa into assisting Atsushi despite their rivalry.

Dexterity: He is extremely skilled in sleight of hand and lockpicking, capable of opening safes with needles, swapping documents unnoticed, implanting bugs, and stealing weapons without detection. Kunikida once described him as “frighteningly dexterous.”

Physical Prowess: Though not physically dominant, Dazai compensates through prediction and nullification. He has temporarily held his own against Chūya Nakahara by memorizing his movements and timing, though he was eventually overpowered.

Heart Rate Manipulation: While imprisoned in Meursault, Dazai demonstrated the ability to consciously manipulate his heart rate, using monitoring devices to encode and transmit messages to the outside world.

OCCUPATION Port Mafia Executive

AFFILIATION Port Mafia

⸻

Chūya is a relatively short young man with a lean yet well-trained physique. He has striking blue eyes and vibrant orange hair, typically worn slightly long with a messy, layered style framing his face. His most recognizable accessory is his black fedora hat, which he rarely removes.

His attire is formal yet distinctive: a black suit with a vest, white dress shirt, black tie, gloves, and a long dark coat draped over his shoulders. His outfit reflects both his status within the Port Mafia and his refined personal taste.

⸻

Chūya is hot-tempered, prideful, and highly confident in his abilities. He is quick to anger—especially when provoked by Osamu Dazai—yet remains deeply loyal to the Port Mafia and takes his responsibilities seriously. Despite his aggressive demeanor, he possesses a strong sense of honor and personal code, valuing loyalty and repayment of debts.

Unlike many members of the Mafia, Chūya is capable of forming genuine bonds and shows concern for his subordinates. He respects strength and despises underhanded tactics when they violate his sense of fairness, though he will still act ruthlessly when necessary.

Chūya was formerly the leader of the Sheep, a group of ability users who relied on him for protection. However, this relationship was exploitative, as they depended on his power while fearing it. His eventual betrayal by the Sheep played a crucial role in shaping his distrust and his decision to join the Port Mafia under Ōgai Mori.

His partnership with Dazai as “Twin Dark” was one of the most feared duos in the underworld. Their teamwork combined Chūya’s overwhelming destructive power with Dazai’s strategic brilliance and ability nullification. Despite their constant conflict, their synchronization in combat is nearly unmatched.

⸻

Ability

Main article: Upon the Tainted Sorrow

Upon the Tainted Sorrow (汚れつちまつた悲しみに, Yogorechimatta Kanashimi ni) grants Chūya the ability to manipulate gravity. He can control the direction and magnitude of gravitational forces, allowing him to: • Increase or decrease weight • Launch devastating high-speed attacks • Manipulate projectiles and surroundings • Enhance his own mobility and physical strikes

This ability makes him one of the most powerful combatants in the series.

⸻

Corruption (Arahabaki)

Chūya possesses a hidden state known as Corruption, where he releases the full power of the entity Arahabaki sealed within him. In this state, his gravity manipulation becomes exponentially stronger, granting overwhelming destructive capability.

However, Corruption comes at a severe cost: • It destroys his body over time • He loses control of himself • It will eventually kill him if not stopped

The only way to safely deactivate Corruption is through Dazai’s ability, making their partnership uniquely interdependent.

⸻

Skills

Combat Ability Chūya is an exceptional close-range fighter, combining martial skill with gravity manipulation to overwhelm opponents. His speed, strength, and reaction time are all enhanced by his ability.

Endurance He has extremely high durability and pain tolerance, allowing him to continue fighting even under severe physical strain.

Tactical Awareness While often overshadowed by Dazai’s intellect, Chūya is far from reckless. He is capable of making quick and effective combat decisions, especially in high-pressure situations.

⸻

Despite his volatile personality, Chūya is defined by loyalty, identity, and control. His struggle with the inhuman power inside him contrasts with his very human desire to belong—making him one of the most emotionally grounded yet dangerous figures within the Port Mafia.

REFERENCE Flawless (Short story by Sakunosuke Oda)

OCCUPATION Mafioso Postman (former) Assassin (former)

AFFILIATION Port Mafia

Oda was a tall man with short dark brown hair that carried a faint reddish tint and dark brown eyes. His hair was slightly parted, exposing a portion of his forehead, and he had light stubble, giving him a calm but mature appearance. His expression was typically relaxed and unreadable, rarely showing strong emotional reactions.

His usual attire consisted of a black-and-white pinstriped collared shirt worn loosely over a beige-brown Kevlar-woven coat with buttoned cuffs. He wore pale gray trousers and light brown shoes. During dangerous missions, Oda occasionally wore a bulletproof vest beneath his clothing, reflecting his practical and cautious combat style.

During his early years as an assassin, Oda wore simpler clothing consisting of a navy collared shirt, work pants, and leather shoes. At the time, he carried two old pistols in shoulder holsters, which became his signature weapons. During this period, Yukichi Fukuzawa described Oda’s eyes as frighteningly empty, lacking visible emotion or hesitation.

Before joining the Port Mafia, Oda worked as a freelance contract assassin. He was highly efficient and professional, completing numerous assignments without hesitation. However, his life changed after encountering a middle-aged man at a café. The man noticed Oda reading two volumes of a novel that he had taken from one of his assassination targets and commented that the final volume of the book was poorly written. The man encouraged Oda to write his own ending to the story and later gave him the final volume with the ending pages missing.

The words spoken to him—“To write novels is to write about humans”—profoundly influenced Oda. Believing that someone who takes lives has no right to write about human experiences, Oda decided to stop killing entirely. From that moment forward, he aimed to become a novelist and dreamed of someday writing stories while living in a room overlooking the ocean.

After abandoning assassination work, Oda joined the Port Mafia. Despite being part of a violent criminal organization, he became widely known as “the mafia member who does not kill.” Instead of assassination, Oda took on lower-profile tasks and occasionally worked as a courier or handled logistical duties. His refusal to kill made him an unusual presence within the Mafia, but his reliability and combat skill still earned him respect.

Following the Dragon’s Head Conflict, Oda adopted five orphaned children who had lost their families during the chaos of underworld warfare. The children—Kōsuke, Katsumi, Yū, Shinji, and Sakura—became the most important part of his life. Because of the dangers surrounding his occupation, Oda entrusted their daily care to a curry shop owner, whom he visited frequently. He financially supported both the shop and the children, forming a quiet but deeply genuine family bond with them.

Oda was widely regarded as a calm, kind, and straightforward individual. Unlike most members of the Port Mafia, he rarely showed cruelty or ambition. Dazai described him as a man without hidden motives, someone who spoke honestly and accepted others at face value. Oda often took Dazai’s sarcastic or absurd explanations seriously, reflecting his literal and sincere nature.

Despite his gentle personality, Oda was an extremely skilled combatant when forced to fight. His fighting ability, combined with his supernatural ability, made him highly dangerous in direct confrontation. Dazai himself warned others, including Akutagawa, never to underestimate Oda’s combat strength.

Oda possessed strong emotional intelligence and observational skills. He was one of the very few people capable of understanding Dazai Osamu on a personal level. Oda recognized Dazai as someone exhausted by existence, describing him as a man who had grown tired of the world and was quietly waiting for death. Oda’s awareness of Dazai’s inner emptiness formed the foundation of their friendship.

During the Dark Era, Oda maintained close relationships with both Dazai Osamu and Ango Sakaguchi. The three often spent time together at the Lupin Bar, where they spoke casually about life, work, and personal beliefs. Among them, Oda acted as a moral center, maintaining grounded views despite living within the criminal underworld.

Oda’s philosophy revolved around the belief that people should strive to become better regardless of their past. This belief culminated in his final conversation with Dazai, where he encouraged him to leave the path of violence and choose a life that saves others. Oda’s final words became the decisive factor that ultimately led to Dazai abandoning the Port Mafia.

Ability

Main article: Flawless

Flawless (天衣無縫, Ten’imuhō) allows Oda to perceive approximately five to six seconds into the future. This predictive ability makes surprise attacks nearly impossible against him, allowing him to react and adjust his actions before danger occurs.

However, the ability has clear limitations. Oda can only see futures that stem from his current decisions. If he changes his actions based on what he sees, a new future forms, which may introduce unforeseen threats. Additionally, traps or events triggered outside the short five-to-six-second window cannot be fully prevented, making the ability powerful but not absolute.

Skills

Marksmanship: Oda demonstrated exceptional firearm accuracy, particularly with dual pistols. His combat style relied on combining predictive foresight with precise shooting.

Combat Awareness: Through both experience and his ability, Oda possessed outstanding battlefield awareness and reaction timing.

Tactical Judgment: While not as strategically manipulative as Dazai, Oda showed strong situational decision-making and survival instincts during combat scenarios.

Emotional Insight: Oda displayed unusual empathy and perceptiveness, allowing him to understand others’ motivations and emotional states with remarkable clarity.

REFERENCE Discourse on Decadence (Essay by Ango Sakaguchi)

OCCUPATION Information agent Special Division for Unusual Powers operative (undercover)

AFFILIATION Special Division for Unusual Powers Port Mafia (former spy) Mimic (former spy)

Ango is a tall young man with short, neatly cut dark hair, styled so that his bangs usually reveal his eyebrows. He has light-colored eyes and wears circular-framed glasses, which contribute to his intellectual and reserved appearance. One of his most recognizable physical features is a small mole located above the left side of his upper lip. His posture is usually upright and formal, reflecting his disciplined personality.

His standard attire consists of a pale brown double-breasted coat buttoned to the left side, worn over a tab-collared shirt paired with a kobicha-colored brown tie. He wears trousers matching the color of his coat and shoes similar in shade to his tie. His clothing reflects his preference for modest professionalism rather than intimidation or extravagance.

During the Dark Era, Ango operated as a triple agent, secretly working for the Special Division for Unusual Powers while infiltrating both the Port Mafia and the foreign ability organization Mimic. His role required extreme caution, secrecy, and psychological endurance, as exposure from any side would have meant immediate execution.

Ango is characterized by his composure, rational thinking, and strong sense of responsibility. Compared to Dazai’s manipulative unpredictability and Oda’s quiet moral steadiness, Ango acts as a pragmatic realist. He values structure, duty, and stability, often acting as the most grounded member of their trio.

Despite his professional detachment, Ango formed a genuine friendship with Osamu Dazai and Sakunosuke Oda. The three regularly met at the Lupin Bar, where they shared quiet conversations and temporary relief from their dangerous occupations. Ango openly acknowledged that Dazai required someone to restrain his destructive tendencies, while he respected Oda’s moral clarity and sincerity.

As part of his duties following the Dragon’s Head Conflict, Ango was responsible for documenting the lives and deaths of fallen Port Mafia members. He carefully recorded their personal histories, family backgrounds, and final circumstances. He also ensured that the relatives of the deceased were notified of their deaths while deliberately concealing any connection to criminal organizations. This task demonstrates Ango’s deep respect for human life and memory, despite operating within morally gray environments.

During his infiltration of Mimic, Ango gathered intelligence on the organization’s military strength, leadership structure, and operational plans. His information ultimately contributed to the chain of events that forced a confrontation between Mimic and the Port Mafia, a conflict that would have lasting consequences for all parties involved.

When Ango’s true identity as a government spy was revealed at the Lupin Bar, his relationship with Dazai and Oda collapsed. Ango attempted to justify his actions by explaining that his loyalty was always directed toward protecting national stability and preventing greater chaos. However, both Dazai and Oda rejected his reasoning emotionally, creating a permanent fracture in their friendship. Recognizing the damage he had caused, Ango chose to withdraw without resistance.

Following the fallout, Ango continued to respect both men, particularly Dazai, though their relationship remained strained. His exhaustion and stress increased significantly, reflecting the emotional burden of balancing loyalty, friendship, and duty. Even after losing their trust, Ango continued to monitor events surrounding them as part of his responsibilities to the Special Division.

Ability

Main article: Discourse on Decadence

Discourse on Decadence (堕落論, Daraku-ron) allows Ango to extract and read memories embedded within physical objects. By touching an item, he can access information connected to its history, previous owners, and events associated with it. This makes the ability extremely valuable for intelligence gathering, forensic analysis, and historical reconstruction.

However, the ability places significant mental strain on Ango. Large or emotionally intense memory fragments can overwhelm his consciousness. In extreme cases, his brain temporarily shuts down while processing excessive information, rendering him physically vulnerable.
