Kogorō Mōri, a private detective and former Tokyo Metropolitan Police Division One officer, once served under Inspector Megure with a focus on marksmanship. Though his investigative skills were middling during his police days, a critical incident led to his resignation: accidentally grazing his wife Eri Kisaki with a bullet during a hostage situation—a detail noted in a film but unverified in the manga. Now operating the Mouri Detective Agency in Beika Town, he shares his home with daughter Ran and Conan Edogawa, a teenager shrunk to child size who secretly aids his cases. Dubbed the "Sleeping Kogorō," his reputation arises from Conan’s habit of incapacitating him via stun-gun wristwatch or tranquilizer dart during investigations. While unconscious, Conan mimics his voice through a voice-changing bowtie, creating the illusion that Kogorō solves cases in his sleep. Despite his comedic persona—marked by laziness, bravado, and a weakness for attractive women like pop idol Yoko Okino—he possesses martial arts expertise, judo proficiency, and sharpshooting skills. Personal stakes, such as threats to Ran or Eri, trigger a serious demeanor, unveiling sharper deductive abilities and emotional intuition. Medical records highlight elevated uric acid and cholesterol levels, common in middle age. A heavy smoker, he indulges in alcohol, horse racing, and baseball, drawing frequent reprimands from Ran and Conan. His marriage to Eri remains tense due to his flirtatious tendencies, though mutual affection persists. Occasional reconciliatory gestures, like gift exchanges, yield uncertain outcomes. In *One-eyed Flashback*, Kogorō investigates a decade-old avalanche linked to Inspector Kansuke Yamato’s past after former colleague Koji Sametani seeks his help. His tenacity underscores loyalty and investigative focus when personally invested, mirroring prior instances like solving a case involving an Eri-lookalike culprit in *Strategy Above the Depths*. These moments reveal latent deductive prowess often eclipsed by Conan’s interventions. Evolving from comic relief to a sporadic bridge between police work and Conan’s covert operations, Kogorō’s acrophobia—once exclusive to films—later surfaces in manga, signaling gradual growth. Though reliant on Conan for most solutions, sporadic displays of competence and a moral opposition to violence balance humor with understated capability.
