Mouri, Kogorou

毛利小五郎

Kogoro Mouri is a private detective and Ran's father. He previously worked in the Tokyo Metropolitan Police Department's First Division alongside Inspector Megure. Although he was an excellent marksman, he was not a particularly skilled investigator. Around the time Mouri left the police force, his wife, Eri Kisaki, also moved out. Despite ten years having passed, they have never officially divorced.
Mouri has an overinflated sense of his own importance and detective abilities. He does not investigate why he suddenly and consistently passes out at crime scenes, only to solve cases in his sleep with deductions different from those he made while awake. He is also frequently unprofessional, often making sarcastic and blunt comments about suspects or even his own clients.
In cases, Mouri is typically lax with his deductions and investigations, following only the most obvious clues or assumptions to reach conclusions that are often silly or fall directly into a culprit's trap. The police, especially Megure, often find him to be an embarrassment while he is awake and hope to see "Nemuri no Kogorou" (Sleeping Detective) as soon as possible. Mouri does have a serious side that emerges only when a case has personal importance to him, such as when Eri and Ran are involved. In such instances, his entire personality and demeanor change, and he begins acting professionally, demonstrating improved deductive skills and cunning. While he does not meet Shinichi's standards and still struggles to find clues, his logical reasoning improves, and Mouri often demonstrates a better sense of interpersonal relationships than Shinichi.
Mouri easily becomes infatuated with beautiful women. His favorite celebrity is pop idol Yoko Okino, and he never misses (or tries not to miss) her television shows. He also keeps a large collection of Yoko-related merchandise, and his office and bedroom feature Yoko posters. Because of his flirtatious behavior around attractive women, he often embarrasses Ran. While it is not stated as the reason why Eri left him, it is one of the primary reasons why she has not returned.
Although never explicitly called an alcoholic, Mouri has a tendency to get intoxicated, and Shinichi/Conan often makes sarcastic remarks about him spending money on alcohol. In the anime, particularly in early episodes, his office is littered with empty beer cans, and he keeps a well-stocked liquor shelf. Mouri is also a heavy smoker and is usually seen with a cigarette in his mouth. Other hobbies include watching his favorite idol star, Yoko Okino, betting on horse races, playing mahjong (which he tends to lose), and playing or watching baseball (he even plays on his neighborhood's team).
Mouri suffers from mild acrophobia (fear of heights) and is quite uncomfortable in high settings where he can see how high up he is. He does not have this fear in the manga.
