Ranpo Edogawa/Relationships

Armed Detective Agency=


 * -|Port Mafia=

Yukichi Fukuzawa
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 CEOs murder. Fukuzawa, impressed by Ranpo's ability to solve the case immediately, takes Ranpo to a restaurant to repay him.

From there, Ranpo pesters Fukuzawa until he takes Ranpo with him on his next job at a theater. Halfway through the play Ranpo starts a commotion, with Fukuzawa ultimately storming outside the theater with the boy. After discovering that Ranpo's loneliness and anger towards other people was caused by Ranpo genuinely believing he was no different nor special than others, Fukuzawa then tells Ranpo a white lie; that he’s an ability user. Ranpo, filled with newfound confidence, solves the case at the theater.

However, Ranpo, at while luring out the organization behind the case puts himself in danger. When Fukuzawa comes to save him, he gets incredibly upset with Ranpo for putting himself in harms way, resulting in Fukuzawa slapping him. Fukuzawa then consoled him.

They stayed together for a while, Fukuzawa going to bodyguard missions (and ultimately not needing to protect anyone due to Ranpo solving the threat), and Fukuzawa accompanying Ranpo on cases, before Fukuzawa realized there was an issue. Ranpo was brilliant but weak, and would need someone to protect him while he solved crimes. And while Fukuzawa could do so, there would come a time where he couldn't. And with that, the Armed Detective Agency was formed.

Ranpo and Fukuzawa are shown as very close, and 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.

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.

Yosano appears to be close with Ranpo. Yosano was the first hire to the agency, after its establishment. When she first came in, Fukuzawa and Mori were fighting over her.

Ranpo took her aside and used Super Deduction to find her missing butterfly adornment gifted to her three years prior, and told her she wouldn’t have to use her ability often as he was the star of the agency. Instead, they wanted her ‘gentleness’, and empathy. This made Yosano cry tears of joy, and helped her break out of her trance-like depressive state.

She's also with Ranpo when they arrived at the location where Poe invited Ranpo for another competition on solving his novel. With Yosano fails to catch the culprit, and eventually falls victim to the murderer, she places her trust in the great detective for whom the Agency was established and thanks him for recruiting her to the organization. As Yosano "dies", Ranpo uses his deduction prowess and solves the case, causing him and Yosano to return to reality They seem to know each-over well, correctly assuming the others moves (like when Yosano asks Atsushi to go shopping).

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.

The two are also shown to be the most intelligent and most capable strategists in the Armed Detective Agency as they worked together to come up with a plan to take down 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 seem to respect Dazai's intellect with Ranpo stating that facing Fyodor Dostoevsky was complicated as it was like facing Dazai.

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
Chūya and Ranpo have briefly interacted a few times, most notably when Ranpo stuck Chūya in a book made by Poe.

Edgar Allan 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. Ranpo also spends his free time at Poe's house, and eating sweets.

Minoura
Minoura was initially hostile towards Ranpo as he believed that he was incompetent and also disliked his arrogant behavior. However, after Ranpo was able to solve the Yamagiwa's murder case, Minoura apologized for doubting his abilities and told him that he will contact him if he ever has trouble with another case to which Ranpo replied that he will gladly help him.
