Wataru Takagi and Miwako Sato
 Relationship analysis
Wataru Takagi and Miwako Sato are two officers working under Inspector Megure in the first division of the Tokyo Metropolitan Police Department, where Sato is currently Takagi's superior. As the story progresses, they start developing strong mutual romantic feelings for one another.
Despite being heavily admired by many male colleagues around her, especially Inspector Shiratori in the beginning, Sato still cares and worries about Takagi deeply, most notably during situations where his safety was put at risk. She also finds in Takagi traits that remind her of her late colleague, Jinpei Matsuda, whom she had become romantically inclined towards in the brief time they've known each other. Takagi, on the other hand, respects Sato as his senior and loves her sincerely as a girlfriend, even to the point of willingly sacrificing his own life just to keep her away from all dangers. After going through numerous difficulties and challenges, in some later cases, their relationship was hinted to have entered a sexual level; however, the true nature of this development has yet to be confirmed.
A running joke in the series is that their relationship never progresses because of interruptions by the rest of the police force or other characters.
 Wataru Takagi and Miwako Sato moments
- Takagi tells the Detective Boys he has someone he likes and it's quickly inferred that it's Sato.
- Takagi is told that there is someone Sato likes in the 1st division and he wonders who it is, and worries if it is Ninzaburo Shiratori.
- Shiratori invites Sato out for dinner at a french restaurant after the case is resolved, and is dejected when he gets rejected by Sato.
- Sato instead invites Takagi out, and then also invites Inspector Megure, making Takagi worried that the one Sato likes might be Megure instead of Shiratori.
- Takagi asks if Sato likes Inspector Megure (in that way), to which Sato replies yes (she misunderstood). She explains it's because he reminds her of her father, and Takagi realises what she means, that he misunderstood (from before). Sato teases and says he looks like he wants to say something more.
- Sato says she used to think she would grant the wish of the person who solves the mystery and catches Shuushirou, prompting Takagi and Shiratori to fantasise about Sato in a wedding dress. The Detective Boys immediately begin listing the wish they would like granted, and Sato thinks that only they would take it so seriously, but then notices the two men (Takagi and Shiratori) who have both gone quiet and looking like they're thinking hard (about their wishes), and she asks, "What's up with you two?"
- Takagi forgets his handcuffs and says the fortune telling magazine says he is super lucky today. It gives Sato flashbacks of the day her father died, when he left home he had forgotten his handcuffs and also said he had super lucky fortune that day. Sato gives old, rusty handcuffs to Takagi, telling him they are a memento of her father's and that it is sure to bring him luck. Shiratori looks decidedly put out.
- Later, Takagi is handcuffed into a building that has been set on fire, Sato wants to rush into the building but is stopped by Shiratori and Megure. As bits of the building crumbles, Sato yells out that Takagi is a baka, with tears in her eyes, only to hear Takagi answering her from behind them.
- Takagi had gotten out, but was still handcuffed to a metal bar, he collapses from the wound to his head, and Sato notices he has a gun and asks him why he didn't just shoot the handcuffs with his gun. The Detective Boys answer that it must have been because the handcuffs were the memento from Sato's father and he didn't want to damage them. Ai remarks that Takagi is the type to die early.
- Sato holds Takagi's unconscious body, and Shiratori stands to the side with his arms crossed.
- To show her thanks and to keep her promise (because Takagi figured out the mystery), she asks what he wants, and he says he wants to go somewhere sometime with her. He thinks it's a date, but Sato drags him along an undercover mission instead.
- As Ran is mulling over her failed attempt to ask about Shinichi's feelings for her, Takagi walks by muttering, "Doing it directly is bad..." about his situation with Sato.
- A ticket to a magic show drops out of his jacket, and when asked, Takagi says that Yumi had an extra ticket and invited him, but that he said he wasn't interested. It was a plan Yumi thought up, to see whether Sato's face would change expression when she heard, but Sato instead encourages Takagi to go.
- Later, Takagi gets a phone call from Yumi asking how it went, he hangs up quickly shouting for her to call him at a better time, and Sato is behind him asking him what Yumi wanted.
- At the end of the episode, Yumi and Sato are talking, and Sato asks if Yumi likes Takagi. Yumi exclaims loudly, and thinks that her plan worked.

- Sato is pressured by her mom to attend an omiai (arranged matchmaking), so she randomly picks one (with her toes no less), and it turns out to be Shiratori.
- Yumi promises to send her "servant" (Takagi) to fake an emergency and save Sato, she texts Takagi but he is caught up with a case and doesn't read the mail until Conan using Shinichi's voice calls him and tells him the situation, that Shiratori and Sato have entered into a wager, if before sunset Takagi does not resolves the case and gets to them in time, Shiratori will take Sato as his wife, if Takagi does make it, then the whole thing will be forgotten.
- Sato agrees and thinks Takagi will definitely come, then she wonders why she thought he definitely would.
- Sato resigns herself to the deal, and thinks herself a failure as a police officer for not having noticed until now just how important Takagi has become to her.
- Just as Shiratori is about to seal their deal with a kiss, Conan uses Araide-sensei's shadow and his voice-changing bow tie to imitate Takagi's voice, stopping the kiss, and the deal.

- Takagi almost gets blown up and Sato frantically tries to rescue him, not knowing that Takagi is safe, burning her hands in the process. The other infer that she was trying to save both Takagi and Matsuda.

- Later in the case, Sato switches places with Yumi to protect her from the culprit. She tries to arrest him when he attacks her, but then she mistakenly pins Takagi down to the ground since said culprit is a man who looks a lot like Takagi.
- Months later, it turns out that a witness to the 'attack' is a famous photographer and has used a picture he took of Sato pining Takagi down in a commercial ad. Sato and Takagi are embarrassed, and Chiba slyly tells Shiratori that he can't take the ads down.

- Takagi (and the rest of the police department) is worried about the sudden appearance of a ring on Sato's left hand.

- Sato and Takagi decide to go to a spa after the case is finished, and this fires up Takagi who takes up a more active role in the investigation. Sato, however, begins to worry when she hears from Superintendent Matsumoto that this is a very bad signal: such reckless behavior is likely to trigger Takagi's death in the line of duty. She is even reminded of her father and Jinpei Matsuda.

- Sato and Takagi put on disguise to catch the culprit at a ramen shop. It's again stated that they're sexually active, as Sato tells Takagi that she plans to work out *intensely* that night to burn out calories (implying that she wants to have sex with him) and is mad when he misses the point of her remark.
- Takagi pretended he is on leave but instead to spend some private time with Sato in Yufuin.
