Clairvoyant
"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

The Clairvoyant 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.

Unnamed Mother
"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 the Clairvoyant despite not being a police officer, detective, or criminal psychologist, she and her 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.

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

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

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, Poe and Ranpo 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 joined the guild just to challenge Ranpo.

But, even though Poe challenges Ranpo (with Akiko Yosano) again, he doesn't win. Even more, Ranpo seemed to not have remembered their original detective battle at first, which greatly upset Poe. Though, after their 'fight', Ranpo remembers Poe and exclaims that it was the first time he'd been pushed that far by another detective.

More recently, when Poe asks for his output or deductions, he doesn't seem to mind it and helps him. 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 ‘fanlike’ 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

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

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

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

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

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

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
