Tetchō Suehiro
"He probably wasn't amazing enough to be known to the public or anything, though. He could never beat my mom when it came to solving mysteries or reasoning, so she always got the upper hand on him when they argued back home."

- Ranpo talks about his father

Tetchō Suehiro is Ranpo's father whom Yukichi Fukuzawa recognized as a legendary detective known to have solved various difficult cases throughout the country. Despite the man's fame and being praised by many for his extraordinary deduction and observation prowess, Ranpo surmised that his father was "not amazing enough" to be popular among the public, since he could never beat his mother in solving mysteries, reasoning, and arguments. Ranpo was also seemingly taught by his father regarding the field, once telling him that fingerprints were easy to falsify.

Ranpo's father once advised him that he shall soon surpass his parents due to his gift and, until the right time, asked him to humbly observe others and learn virtue until he could grow with good judgment and knowledge about how the world worked, though Ranpo did not quite understand what his father meant. Ranpo also went to Yokohama and entered the Yokohama Police Academy as instructed by his father if anything were to happen to him, an endeavor Ranpo did following his parents' death due to an accident.

Saigiku Jōno
"Don't think you can control me with a few compliments. My mother told me to never look down on others."

- Ranpo echoes his mother's teaching to Fukuzawa

Ranpo apparently looked up to his mother's deduction skills, able to best his father in deductions and arguments. Sharp enough to go up against Tetchō Suehiro despite not being a police officer, detective, or criminal psychologist, he and his spouse partook in raising Ranpo as an ordinary child to protect his extraordinary gift, teaching him never to look down on others and to observe the people around him until he could understand them. Ranpo was often told by his mother that he was "still just a kid", which Ranpo correlated with adults being "smarter" than him and caused him over time to develop the perspective that adults thought and noticed things like him.

Yukichi Fukuzawa
"Your point of reference may be justice, but mine is to face the same direction as the President."

- Ranpo to Ōchi Fukuchi

Fukuzawa took Ranpo in as an orphan twelve years ago. Fukuzawa first met Ranpo after running into him on a job where Fukuzawa was working as a bodyguard for a CEO's murder. Ranpo came into the room where Fukuzawa was meeting the late CEO's secretary, looking for a job, and continued to ramble before offhandedly remarking that the secretary killed the CEO. Fukuzawa, impressed by Ranpo's ability to solve the case immediately, took Ranpo to a restaurant as he had promised earlier.

From there, Ranpo pestered Fukuzawa until he took Ranpo with him on his next job at a theater which had received a death threat. Halfway through the play Ranpo exclaimed how bizarre other people were that stirred a commotion, with Fukuzawa ultimately storming outside the theater with him. After talking to him and discovering that Ranpo's loneliness and anger towards other people were caused by Ranpo genuinely believing he was no different nor special than others, Fukuzawa told Ranpo a white lie that he's an ability user. Ranpo, filled with newfound confidence, solved the case at the theater using the pair of glasses given to him by Fukuzawa to help him "control his ability".

However, while luring out the V|organization behind the case, Ranpo was put in danger after going with a police officer during the case, apparently knowing that he pulled the strings behind the incident and confident that Fukuzawa would come save him on time. When Fukuzawa arrived to save him, he got incredibly upset with Ranpo for putting himself in harm's way, resulting in Fukuzawa slapping him. Ranpo cried, before Fukuzawa consoled him and took him with him.

They stayed together for a while, Fukuzawa going to missions where he acted as a bodyguard (and ultimately not needing to protect anyone due to Ranpo solving the threat beforehand), and Fukuzawa accompanying Ranpo on cases. However, it didn't take long before Fukuzawa realized that Ranpo was brilliant but weak, and thus he needed someone to protect him while he solved crimes. While Fukuzawa could do so, he knew there would come a time where he could not, so he established the Armed Detective Agency who could protect Ranpo at all times while they, led by Ranpo, solved crimes and cases throughout Yokohama.

Over time, Ranpo and Fukuzawa grew to be quite close, their relationship being hinted towards a parent–guardian one. Fukuzawa, though sometimes annoyed with Ranpo, puts up with it out of deep care and respect for him. As for Ranpo, he seems to have a deep-seated admiration for Fukuzawa, doing things simply for the sake of being praised by him and becoming incredibly depressed when harm befalls him.

For someone who values logic for his actions, he is nonetheless willing to heed Fukuzawa's order simply because he "said so" and does not need any other reason or explanation for obeying the President's instructions out of genuine trust and faith in him, though Ranpo initially got seemingly intimidated when planning on diverting from or disregarding the President's order. Moreover, Ranpo's concern towards Fukuzawa's well-being extends to disobeying him if the need arises, such as leading the fight against the Port Mafia despite Fukuzawa's strict order not to engage them, all for the sake of protecting him.

Akiko Yosano
"Join the Armed Detective Agency. We don't want your ability. We want that kindness of yours."

- Ranpo recruits Yosano to the agency

Ranpo appears to be quite close with Yosano, hiring her after its establishment. While Fukuzawa and Ōgai Mori were fighting over her custody, Ranpo took her aside, used Super Deduction to find her missing butterfly adornment gifted to her three years prior, and assured that she wouldn't have to use her ability often as he was the "star of the Agency". Instead, they wanted her kindness and empathy. This made Yosano cry tears of joy, helping her break out of her trance-like depressive state.

She also accompanied Ranpo when they arrived at the location where Edgar Allan Poe invited Ranpo for another competition on solving his novel, which soon trapped them in the novel's setting. When Yosano failed to catch the culprit and eventually fell victim to the murderer, she placed her trust in the great detective for whom the Agency was established and thanked him for recruiting her to the organization. As Yosano "died", Ranpo used his deduction prowess and solved the case, apparently the first time without relying on his glasses and "ability".

They seem to know each other well, with Ranpo correctly anticipating Yosano's quirks and hobbies like asking someone in the Agency to accompany her shopping. On casual occasions and even during the Guild war, Ranpo invited Yosano to play a game with him, particularly, while Yosano accepted and fiercely asked what their wagers shall be. Despite their friendly rapport, Ranpo is also wary and seemingly frightened of her treatments like the other Agency members.

Doppo Kunikida
"Kunikida. You are the noblest, strongest member of the Agency. That's why our enemy tried to break you first. Keep that in mind."

- Ranpo's view towards Kunikida

Ranpo is often praised by Kunikida like the rest of the Agency and widely sought for his deduction "ability", with Ranpo pridefully taking his compliments and need for his gift. Nevertheless, recognizing Kunikida as Fukuzawa's apprentice, Ranpo places his trust in Kunikida as their acting president during the President's affliction and offered to read through any vital intel that can help them in their battle under Kunikida's leadership. Ranpo also considers Kunikida as the Agency's noblest and strongest member, which he deemed to be taken advantage of by their enemy during the Cannibalism operation and understood if he did not wish to bend the rules, especially in the midst of his erstwhile broken state.

Subsequently, Ranpo felt a sense of accountability during Kunikida's arrest after a child died during his and Atsushi's failed chase for Alexander Pushkin. Though Kunikida considered himself a suspect and therefore worthy of being imprisoned, Ranpo insisted on getting him out of jail and swore to clear his name. After all, Ranpo claimed that he would not be arrested had he seen through and stopped Fyodor's scheme in the first place. True enough, Ranpo went through all possible methods to pressure Mushitarō Oguri into retracting his evidence-suppressing ability, which ultimately resulted to Kunikida's release.

Osamu Dazai
"A coworker and an enigma, even to me."

- Ranpo describing Dazai to Minoura

Ranpo and Dazai are shown to be on good terms with each other. Both have eccentric personalities and seem unbothered by it which is shown during the Yamagiwa's murder case when Ranpo simply reacts to Dazai's theatrical attitude by stating that he's always like that and describes him as an enigma. During their first encounter, Ranpo seemed to deduce Dazai and asked him about his prior engagement before entering the Agency, to which Dazai ambiguously responded. After a few seconds of silently staring at Dazai, he reverted back to his usual disposition "as if nothing happened" as Kunikida observed and simply welcomed the newcomer to the Agency.

The two are also considered as the most intelligent and capable strategists in their organization, renowned as the Agency's sharpest detectives (双璧,), having notably worked together to come up with a plan to infiltrate the Moby Dick. On top of that, despite Ranpo stating that he is better than Dazai and is still not quite to his level yet, he seems to respect Dazai's intellect and once admitted that facing Fyodor was complicated and like facing Dazai.

The duo's dynamic seemingly persists in many other instances, quite unseen or indirectly. Such include the aftermath of the Yokohama fog incident, particularly when Ranpo returns to reality and calls out to Dazai by himself after accurately predicting the situation's outcome, and during one of the Agency's cases in Standard Island, in which Dazai tipped the absent Ranpo on their endeavors in the island; from merely relying on Dazai's intermittent reports, Ranpo eventually led their rescue from what escalated into a dire situation in the island, saving the Agency and the island's residents.

Jun'ichirō Tanizaki
Like the other Agency members, Ranpo takes sympathy on Tanizaki whenever he recounts his treatments with Yosano. Professionally, they appear to have mutual trust in each other, Ranpo once sending in Tanizaki alone to leverage with the Mafia in the midst of the Cannibalism operation and worrying for his well-being after realizing that his strategy had been anticipated by Fyodor.

Initially, some of their ideas clashed, one notable example being Ranpo's refusal to help retrieve Atsushi from his Mafia abductors—which he saw as a personal issue they must not meddle with—in contrast to Tanizaki's proposal to rescue him as one of their own. Nevertheless, they would apparently come to terms after Fukuzawa's personal intervention to have them save Atsushi. Ranpo also mentioned that he would normally contact either Tanizaki or Kunikida to fetch him back to the office.

On the eve of Atsushi's entrance exam, Ranpo bid Tanizaki good luck even before he was set to act the main role of a bomber and later left some scribblings of the office floor on the ideal places where a bomber could barricade before leaving for case in the. Tanizaki took these up to be some form of message to cheer him on, which also left him in awe at how Ranpo was able to make out the exam's details even before they themselves could finalize their plan.

Atsushi Nakajima
"Atsushi-kun! Go handle this job! […] I can't do it! This pastry's all warm 'n' tasty right now! I can't leave it."

- Ranpo arranges for Atsushi to take on his orphanage director's death case

Ranpo initially did not mind Atsushi as their erstwhile latest newcomer, albeit not to the point of hostility, and mentioned that he did not need his assistance in solving a case but rather in heading to the crime scene. Ranpo was also firmly against rescuing Atsushi when he was taken by the Mafia, insisting that the bounty on his head was not theirs to interfere with nor did Atsushi seek the Agency for his protection. Nevertheless, upon Fukuzawa's direct request, Ranpo helped in deducing Atsushi's location.

Over time, however, Ranpo and Atsushi grew to develop a friendly and professional relationship. For instance, Ranpo handed a case over to Atsushi, keeping to himself initially that the case victim was Atsushi's orphanage director and is therefore quite fragilely personal for Atsushi; he also provided him some hints if Atsushi were to ever get stumped along the process. In other occasions, Ranpo would also ask Atsushi to piggyback him as a means of transportation, similar with Kenji.

Ranpo would also notably fall for Atsushi's "bribes", particularly a, in exchange for carrying out some favors. In one instance, Ranpo accepted Atsushi's Ramune offering to use Super Deduction in finding out Kamui's real identity despite telling Atsushi not to rush things as part of their systematic plan by Fukuzawa, eventually leading Ranpo to identify who Kamui is. In so doing, Ranpo apologized for being "wrong" and saved Atsushi from getting slashed by Kamui, afterwards instructing him to run to save his life rather than taking on their enemy by himself.

Kyōka Izumi
"This is the candy I mentioned! It changes color upon squeezing! Go ahead! Knead it in your hand! […] But it's all mine to eat, got it?"

- Ranpo's enthusiasm during Kyōka's arrival in the Agency

Despite not having many interactions, Ranpo is the most excited among the Agency members when Kyōka first came to their office, even buying candies and teaching her how to make it. They are also described to be looking like "grade school siblings" together by Atsushi.

Kenji Miyazawa
Ranpo appears to get along well with Kenji in the Agency, who also showers him with compliments as a great detective. They are occasionally shown taking breaks together alongside other Agency members like Kunikida in their office or with Yosano, Tanizaki, and Dazai at Café Uzumaki, especially after the Guild war. Moreover, Ranpo reveals requesting Kenji, and also with Atsushi, to piggyback him as his means of "transportation".

Chūya Nakahara
"Oh, I'm afraid that won't do, Mr. Fancy Hat. By my deduction, you'd reduce our chances of winning. Thus, I'm here to stop you."

- Ranpo taunts Chūya

During the events of Cannibalism, Ranpo viewed Chūya as one of the Mafia's greatest chances of defeating the Agency, hence devising a plan involving Poe to transport them out of the battlefield. During their confrontation, Ranpo taunted the Mafia executive that he would stop him. Chūya was unnerved by his threat, even recognizing Ranpo as the Agency's linchpin yet not a combat-oriented member. Ranpo shot back by recounting how Chūya lost before to Dazai, a non-combat-based ability user himself, which provoked Chūya and ultimately fell for Ranpo's trick.

Referring to Chūya as Mr. Fancy Hat since their first encounter, Ranpo later informed the Agency once escaping the novel how Chūya got stuck in the novel world and ended up killing everyone, showcasing how Ranpo did not mind for the Mafia executive and leaving him behind by himself.

Edgar Allan Poe
"I remember it like it was yesterday, we tested each other's wits right here. That's the only time another detective's given me the chills… Never before, never since."

- Ranpo remembers and acknowledges Poe

Six years ago, Ranpo and Poe took a case together in which they decided to have a detective battle. However, Poe lost and fell into a depression where he cut off ties with his family and friends. For six years afterwards, he started working on a plot to get back at Ranpo. He eventually joined the Guild just to challenge Ranpo.

However, even though Poe challenged Ranpo (with Yosano) again, he did not win. Even more, Ranpo initially seemed to not have remembered their original detective battle at first, which greatly upset Poe. Nevertheless, after this encounter, Ranpo admitted that he remembered Poe and exclaimed that it was the first time he'd been pushed that far by another detective. From then on, Ranpo would request Poe to bring him some more of his manuscripts, though Ranpo would easily solve his cases from only reading his stories'.

Following the three-way conflict, when Poe asks for his output or deductions, Ranpo doesn't seem to mind it and helps him. In a similar way, Ranpo would seek out Poe's help in various occasions like rescue operations even if Poe does not have a certain affiliation towards Ranpo's targets, particularly the Agency. Moreover, Ranpo has one of Poe's novels as his "10,001 Shelters", where he could retreat to in times of emergency and would have Poe create safe novel settings for his and his peers' interim hideouts.

Poe seems to still refer to Ranpo as his rival, but Ranpo calls him his friend instead. It is often remarked that Poe's so-called rivalry towards Ranpo is odd considering his obvious admiration and fan-like behavior towards him. More recently, Ranpo spends his free time both at Poe's house and eating sweets.

Mushitarō Oguri
"Mushitarō-kun, you've won! I knew from the start that regular people can't defeat ability users. But I'm still going to defeat you. Why? Because my friends think I'm invincible."

- Ranpo accepts the challenge posed by Mushitarō

Mushitarō is thus far one of the few individuals who baffled Ranpo due to his evidence-suppressing ability, a natural weakness to Ranpo's deduction technique. Though Ranpo appeared downcast and straight-out announcing his surrender after failing to pinpoint the criminal to the falling murder case, he nonetheless worked to the best of his abilities and eventually cornered Mushitarō, identifying him as the culprit to the incident and in another case.

Mushitarō, being Fyodor's accomplice, naturally had few tricks up his sleeve, but Ranpo, admitting that he himself took in Fyodor's methods in himself as well, was able to back him up the wall by using his friend Yokomizo's final work as Mushitarō's weakness against him. Ranpo threatened to expose the late author's connivance with Mushitarō to the public that the latter feared would defame his legacy, ultimately compelling him to surrender just as Ranpo expected.

Nevertheless, Ranpo promised that he would help grant Mushitarō a job if he were to lose one, directing him to a government spy whom he could help out and even to the Special Division for Unusual Powers where he could potentially utilize his ability. Ranpo also burned the original final page of the manuscript that contained Mushitarō's tears, possibly to prevent his identity getting identified. Subsequently, upon Nikolai Gogol's arrival, Mushitarō warned Ranpo not to take the Agency's next big case which would destroy them, a request Ranpo honored by turning down unlike the others.

Fyodor Dostoevsky
"The Agency has fallen to Dostoevsky once. It won't lose again. I won't let him hurt a single person there."

- Ranpo's unyielding aura against Fyodor

With his own deduction technique used against himself, Ranpo admitted Fyodor to be a master of cunning, not unlike going up against Dazai. As such, he himself believed there was no way to overturn his intricately-laid traps in time, forcing them to take on the Mafia and play right into Fyodor's hands.

Though the Cannibalism operation ended with Fyodor's arrest, its aftermath placed his subordinate Kunikida into jail and the others into punishment, including himself, for disobeying the President's orders. Moreover, on a deeper level, Ranpo felt accountable that he was not able to see through Fyodor's schemes, which he reckoned might have ultimately prevented a child from dying in Kunikida's midst and thus from getting him imprisoned.

Hence, he revealed having scrutinized Fyodor's methods and eventually took in the Conjurer himself, close to being willing to adopt any and all possible means not to place anyone in the Agency in danger or to lose to Fyodor again. Even Mushitarō noted Ranpo's aura when urging him to surrender to be akin to Fyodor's himself, eventually leading him to turn himself to the police.

Ōchi Fukuchi
Ranpo first met Fukuchi at the founding of the Agency, where the latter, arriving drunk at the venue, stirred some commotion and even pissed on the Agency's doorplate. Ranpo became quite annoyed at the man, something he admitted happened very rarely. Nevertheless, Ranpo learned that Fukuzawa found him quite reliable, though Fukuzawa wondered if Fukuchi was quite lonely that he found his life's path before his childhood friend.

At some point and until his adulthood, Ranpo seemed to be "envious" of Fukuchi's relationship with Fukuzawa, as Fukuchi reasoned out how he and Fukuzawa spent more time together as friends compared to Ranpo. As such, he acted quite sulkily in Fukuchi's midst, with Atsushi noting it to be the first time he had seen Ranpo like such.

It was only after he deduced Kamui's identity and uncovered Fukuchi as the Decay of Angels' mastermind that he most likely changed his perspective on the man, warning Atsushi to flee from him instead of fighting him. Despite being or, more so, especially as a friend of the President, Ranpo devises the Agency's strategy to stop Kamui's plans from further escalating.

Minoura
"If you ever need my ability, do not hesitate to call! We'll throw in a discount from now on."

- Ranpo offers his services to Minoura and the police

Ranpo and Minoura met on callous terms; as Minoura doubted Ranpo's aptitude as an "amateur", while Ranpo boasted about his ability that would not require any sort of investigation. Instead, he assured the officer that he would figure out the culprit and the details of the case like a divine revelation.

Ranpo soon dissipated Minoura's mistrust when he correctly deduced Officer Sugimoto, Minoura's subordinate, as the culprit. After the interrogation, Ranpo opened his services to Minoura and promised to "throw in a discount" for him. Since then, Ranpo would occasionally cross paths with Minoura either from the police seeking Ranpo's help or during other cases.

During his infamous broadcast as a wanted terrorist, Ranpo was able to tap into Minoura's belief system, as well as other police officers', which urged Minoura to break him out of a police car and to help him escape. Though Minoura anticipated how the great detective had the situation under control despite dividing the police forces throughout Yokohama, Ranpo admitted his uncertainty if anyone would even believe in his words.

Officer Sugimoto
"Okay, Sugimoto-kun, you're the detective now! Solve this case for us within sixty seconds!"

- Ranpo challenges Sugimoto to solve a case

Unlike Minoura, Sugimoto seemed unhostile towards Ranpo and openly explained the few details they found out from Yamagiwa's corpse. However, Ranpo apparently saw through him possibly with ease and did not hesitate to point him out as Yamagiwa's killer. Ranpo also interrogated him alongside Minoura, pressuring him into revealing the evidence after Ranpo correctly recounted Yamagiwa's last words to Sugimoto.

Jun Mitamura
"‘Negotiate’? I have no intention of negotiating, and when the conversation doesn't interest me, it just goes in one ear and out the other. Just sounds like a cow mooing to me. Moooo."

- Ranpo absentmindedly provokes Mitamura

After Ranpo became an instant detective sensation for solving the theater incident, Mitamura was quite an avid fan of Ranpo and kindly escorted him into his vehicle. Along the way, Ranpo sensed that Mitamura did not actually believe him to be an ability user, during which the officer gradually exposed his hidden persona as part of an organization known as V, though Ranpo remained unfazed.

Ranpo then provoked Mitamura from warmly attempting to recruit him into angrily threatening Ranpo with his gun out of agitation, his blabbering being constantly compared by Ranpo to that of a cow mooing. Mitamura eventually failed in taking Ranpo in their organization due to Fukuzawa's timely arrival, which Ranpo expected.

Egawa
"The adult world is so bizarre. What made her so mad?"

- Ranpo's confusion to Egawa's anger after deducing her personal life

Meeting Egawa in his adolescence, Ranpo perceived the theater owner like any other adult, called her "old", and directly asked her to hire him at the theater, though he showed disinterest immediately after learning that there were other applicants for the job. Once he correctly deduced her personal life, Egawa grew flustered and walked out on him, leading Ranpo to yet again view her as bizarre like other adults.

Later on, however, the two were able to warm up to each other. Ranpo deduced that she never wished to be a theater owner but to get involved in stage production, which he helped her accomplish during his strategy of exposing the theater murder case to the audience. He even entrusted her to relay his messages to Fukuzawa about the two interrelated cases at the time.

Tokio Murakami
"''The silicone padding, the hospital, the blood—there was so much evidence that you didn't even have to go looking for it. All that's left is a confession. That's why I prepared a place better suited for you than a dismal, boring interrogation room with the police. Enjoy."

- Ranpo exposes Murakami to the theater audience

When Ranpo first met the thespian Murakami with Fukuzawa, Ranpo and Murakami did not see eye to eye regarding the art of acting. Ranpo found that the play might only bore him, which Murakami nonetheless acknowledged and thought such answer befitted a "brat" like Ranpo. Following Murakami's "death" onstage, Ranpo soon uncovered him to be the culprit all along who faked his own demise.

Ranpo initially thought that Murakami was amazing, having been able to achieve what could hardly be done, but once he directed Murakami to their audience, he challenged Murakami's perception towards what entertainment is. Ranpo noted that the audience were amazed not by his onstage death that he wished so hard to act out but rather by his performances, a truth that broke Murakami and made him realize that he was merely performing for himself.
