Juzo Megure serves as a police inspector in Division 1 of the Tokyo Metropolitan Police Department. He is approximately 41 years old, possessing a large build, thick mustache, and thick eyebrows. He habitually wears a hat in public to conceal a scar on his head, a permanent reminder of an incident early in his career where he intervened to save high school student Midori from a serial hit-and-run driver. This event led to their eventual marriage, though Megure remains self-conscious about the circumstances surrounding their relationship's origin.
Megure maintains a long-standing professional relationship with detective novelist Yusaku Kudo, having frequently consulted him on complex cases in the past. Yusaku often brought his young son Shinichi Kudo to these consultations, significantly influencing Shinichi's early development as a detective. Megure holds Shinichi in high regard for his deductive abilities and regularly sought his input on challenging investigations prior to Shinichi's physical transformation. Conversely, Megure typically views Conan Edogawa (Shinichi's shrunken alter ego) and the Detective Boys as nuisances during investigations, despite their frequent contributions to solving cases.
His professional history includes previous collaboration with private detective Kogoro Mouri when both served in the police force. Megure expresses skepticism about Kogoro's investigative abilities and often remarks on the apparent "jinx" surrounding Kogoro, noting that murders frequently occur in his vicinity. Nevertheless, Megure consistently appears at crime scenes to lead investigations and interview suspects, typically accompanied by subordinates Wataru Takagi, Miwako Sato, Ninzaburo Shiratori, and Kazunobu Chiba.
Megure demonstrates a capable but conservative approach to police work. He exhibits genuine concern for his subordinates' well-being yet displays limited patience for ineptitude or obstruction during investigations, occasionally resulting in emotional outbursts. His investigative methods prioritize established procedures over unconventional thinking, which can restrict flexibility in complex cases. He possesses a strong sense of justice and high pain tolerance, evidenced by continuing work after sustaining injuries like head trauma or abdominal stab wounds.
In the Episode One special, Megure responds to a murder at Takanori Sewa's private mansion where bank president Tetsu Yamazaki was stabbed to death. During this investigation, he relies heavily on Shinichi Kudo's deductive reasoning to solve the locked-room mystery, leading to Sewa's apprehension after Shinichi exposed Sewa's feigned disability and method.
Megure maintains formal yet familiar address patterns, typically using honorifics like "-kun" for younger individuals or colleagues. He is commonly addressed as "Inspector Megure" or "Keibu" by most characters, though Kogoro uses "Inspector-dono" and Ginzo Nakamori occasionally employs the nickname "Raccoon-dog Megure". His linguistic and technological limitations are occasionally noted, including difficulty with English pronunciation and challenges operating modern devices. Some anime-original episodes depict him delivering moral lectures to culprits after capture, a trait less frequent in manga-based storylines. Throughout his appearances, Megure remains a constant presence at Tokyo crime scenes, providing investigative stability while often depending on exceptional deductive talents like Shinichi's to resolve perplexing mysteries.
