Twelve years ago, before the Agency was founded and Fukuzawa was still under Sōseki Natsume's tutelage, he wore a black hakama (a pair of large, pleated, traditional trousers), a kimono underneath a longer haori and a small scarf with a circle pattern on it.

Kunikida is very professional and diligent when it comes to his job, because to him, the reputation of the agency takes precedence over anything else. He constantly feels the need to organize, gather, and schedule everything, which is why he comes off as somewhat strict and harsh during investigations.

He is also practical to a fault, as he almost considered abandoning a kidnapped Atsushi Nakajima, because the boy's presence might implicate the Agency. He also once advised Atsushi to give up on the wanted Kyōka Izumi, lest his one-man boat might sink the both of them if he saves her, though he soon encourages Atsushi later on when the latter shows resolve to rescue her.

Though he often appears calm and careful, Kunikida is also known for his exasperated outbursts, which are primarily caused by his partner, Osamu Dazai, who constantly vexes him with his suicidal attempts. However, Kunikida never genuinely disliked Dazai. He acknowledges Dazai's skill and knowledge. when first working with him, and he entrusts much of the Agency's strategies to Dazai. Kunikida extends similar faith to Ranpo Edogawa. Despite this, Kunikida is nonetheless a trustworthy and loyal detective upon whom many in the Agency rely on because of his authoritative capability and responsible nature.

Ranpo Edogawa

Ranpo Edogawa is a member of the armed detective Agency. Despite not being an ability user, he is known as one of the best detectives highly sought by the police, renowned by his comrades, himself, and others as the "greatest detective in the world"

Ranpo is a 26-year-old detective with a youthful appearance, messy black hair, fair skin, and brown/green eyes that are usually kept closed. He wears a brown detective cape (inverness cape), matching hat, blazer, striped tie, and white long socks, often putting on black glasses to "activate" his ability.

Ranpo takes extreme pride in his "ability" which can solve any mystery in mere seconds, with which he has solved countless cases. With his incredible intelligence, he is commended for it by the rest of the Armed Detective Agency, even more so because he lacks an ability. He is often found bragging about his status as the greatest detective in the world. Ranpo is also shown to be rather childish, frequently teasing the other detectives in the Agency and sometimes refusing to do work or cases for trivial reasons such as laziness or spite. Ranpo loves eating snacks too from his snack stash. Ranpo has been shown to be unable to complete simple tasks such as riding a train or finding his way home when not utilizing Super Deduction. However, despite this demeanor, Ranpo becomes serious and calm when the situation calls for it. Because of the Agency's faith in him, Ranpo equally places his trust in them. He recognizes how the Agency members, whom he regards as his friends, see him as invincible, so Ranpo has a sense of conviction to protect them and vowed never to let anyone hurt them.

Kenji is a young boy with gold eyes and short blond hair that reached past the nape of his neck. His bangs are gathered at the center of his forehead, and he had freckles across his cheeks.

He wore blue overalls that are cuffed and a black belt around his waist. His overalls are worn over a loose beige shirt that has tattered sleeves. He wore a black undershirt that has sleeves ending a little past the elbows. He wore an old straw hat around his neck. He usually goes barefoot but is sometimes shown wearing sandals.

Hailing from a small rural village, Kenji is a simple but carefree and hospitable boy, who never fails to greet people with a smile on his face. It's this welcoming disposition that makes him quite popular with the residents in the city. He carried an exceedingly optimistic outlook and always believed in the innate sincerity of others, regardless of what they may appear, say, or do. His obliviousness to the dangers some situations pose may be attributed to his rustic upbringing, but it's a mentality that has aided him in several investigations, given his high track record in solving difficult cases. Specifically, he interrogates suspects straightforwardly regarding their possible involvements in cases and, when they would naturally deny his allegations, Kenji would simply believe them and take his leave, even thanking them for their cooperation. In addition, since Kenji is from the countryside, he is unable to comprehend basic urban concepts such as money and often has to rely on his rural instincts. He once agreed to join and help them in risking their lives to fight the Port Mafia for the sake of protecting the President, despite admitting himself that he does not fully know whether doing so is the right thing or not. Despite this gentle and caring side of Kenji, he has a "menacing side". According to Kunikida.

Yosano is a member and personal physician of the Armed Detective Agency. Her ability is a rare healing ability, Thou Shalt Not Die. a powerful healing ability that instantly regenerates any physical injury. It requires the patient to be on the brink of death (half-dead) to work, forcing Yosano to often use her medical tools to severely injure them first to activate it. 

Age: 25 Height: 5'5 Birthday: December 7

Yosano is a young woman who takes care of her appearance. She has straight, dark hair cut into a bob that reaches past her chin and bangs. Her eyes are magenta. She wears a white button-up blouse with puffy sleeves that end in the middle of her forearm. Her shirt is tucked into a plain black skirt that flares out above the knee. She wears gloves that reach past her wrist, a black tie, and black tights. Yosano wears red high heels and a golden butterfly hairpin on the left side of her head.

She carries herself with grace and dignity. She prides herself on being both a strong woman and a capable doctor, which is why she does not take too kindly to those who belittle her in both respects. She is a feminist who believes that now is the age of equal rights for men and women. She is almost always depicted as calm and composed, but when angered she is quite to contend with, often sadistic in her retaliation

She's also prone to prominent sadistic and aggressive tendencies, which are amplified by her ability's conditions. As a result, most members from the Agency flee when in her presence; Junichiro Tanizaki specifically advised the newcomer Atsushi Nakajima to avoid getting injured even in the slightest to avoid experiencing her unique brand of "treatment". Even the members who entered the Agency around the same generation as her, including Ranpo and Kunikida, recoil from the thought of getting "treated" by Yosano. Moreover, she has a penchant for the morbid and the gruesome, notably gleefully taking apart her patients and healing them with her ability afterwards.

Tanizaki has a slim, average build with orange hair, hazel eyes and pale skin. His hair is parted in the middle with its spikes sweeping downwards, along with a light grey bobby pin clipped on his left. He wears earrings with the corresponding color of his pin. His attire consists of an oversized, off-white V-necked sweater with a black stripe on the collar, light blue pants, and brown shoes. A red sweater is wrapped around his waist. Tanizaki also dons a black tank top underneath his sweater.

Hes arguably one of the most average members of the Agency, not being eccentric or loud like the other members. But he goes along with their shenanigans, especially when specifically instructed by his senior members like Kunikida. He once hinted on feeling quite mediocre as a detective with an ability "not too useful for battle". He also never hesitates to apologize for his behavior, when necessary, specifically when he apologized to Atsushi for his rude role in his entrance exam, even when that was what was expected of him for his role. Nevertheless, he has a tendency to get nervous. Despite being the humble and somewhat carefree type, Tanizaki gets extremely violent and bloodthirsty towards those who hurt his sister Naomi. He tends to get embarrassed by his sister's constant antics and physical intimacy, but he nonetheless cared deeply for her. He even stated that things such as morality, ego, and pride do not matter to him compared to Naomi and would gladly burn the world for her.

He cares deeply for the well-being of his fellow Agency members, but he has a very fragile sense of morality, in which he quickly takes the path that is most likely to preserve himself and the Agency.

Naomi Tanizaki is an office staff at the Armed Detective Agency and the adoptive younger sister of Jun'ichirō Tanizaki.

Naomi is a high school-age girl with hip-length black hair that is styled in a side-swept hime cutand dark grey eyes. She also has a beauty mark underneath her left eye. In general, her appearance does not resemble her brother, given her charismatic allure compared to Tanizaki's timid disposition. She wears a standard seifuku that consists of a white long-sleeved blouse attached with a red sailor-style collar and a black pleated skirt that comes above her knees. She also dons black socks that reach the middle of her calves and a pair of brown loafers.

Naomi is a bold and strong-willed young girl, who never shies away from involving herself in a case—more specifically, ones that involve her older brother's well-being. Despite not being an ability user, she is often embroiled in the Agency's conflict, but when told to leave, she mostly refuses

As an Agency clerk, Naomi is rather intelligent and quick-thinking, even amidst perilous circumstances. She is also shown to be mentally resilient because, in spite of being a near-frequent victim to kidnappings and ability users, she takes it quite well and is outwardly unaffected. Moreover, she appears to be courteous towards Agency clients. Probably one of Naomi's most prominent characteristics is her deep-seated love for her elder brother, whom she is always with. When with her brother, she can be both childish and provocative.
