Relationship analysis

Takagi and Sato

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.[1] 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.[2]

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.

However, he is caught up with a case and doesn't read the message until Conan, (who happens to be there eavesdropping with Araide sensei, Ran and Sonoko at the time) calls him using Shinichi's voice and explains the situation. He also helps Takagi with the case.
  • Sato, who had just agreed to the wager, thinks that Takagi will definitely come, and then, blushing, she wonders why she thinks that.
  • As the sun is about to set, Sato resigns herself to the deal and thinks herself a failure as a police officer for not realizing until just now how important Takagi has become to her.
