Kogoro Mouri, a private detective and former Tokyo Metropolitan Police Division One officer under Inspector Megure, leverages his renowned sharpshooting and judo expertise from his law enforcement career. His departure from the police force is rumored to connect to a hostage incident where he allegedly grazed his wife Eri Kisaki’s leg with a bullet to save her—a detail unconfirmed in the manga. Now operating the Mouri Detective Agency in Beika Town, he lives with daughter Ran while maintaining a strained yet affectionate dynamic with Eri, who moved out ten years prior. Their unresolved feelings surface through mutual jealousy during his flirtatious interactions with other women. Dubbed “Sleeping Kogoro” due to Conan Edogawa’s habit of tranquilizing him to impersonate his voice during case resolutions, this method originated when Conan knocked him unconscious with an ashtray to prevent a wrongful accusation. The tactic evolved into using a stun-gun wristwatch, cementing Kogoro’s reputation for apparent incompetence. However, he exhibits genuine deductive skill when emotionally invested, such as independently solving a hot springs murder involving a college friend—prompting Conan to discreetly guide him without sedation. In *Strategy Above the Depths*, he cracked a case unaided after recognizing the culprit’s resemblance to Eri. His personality merges laziness, chain-smoking, and indulgence in alcohol and gambling with an unwavering moral code against murder. He frequently embarrasses Ran by shamelessly flirting with clients or idolizing pop star Yoko Okino, whose posters adorn his office. Occasional depth emerges through acts like defending the falsely accused or showing compassion for animals. Health issues include high cholesterol and uric acid, alongside a later-developed fear of heights—initially anime-exclusive before entering manga canon. Though his investigations often seem lax, they adhere to police protocols, earning continued respect from former colleagues like Megure, who acknowledges his past effectiveness. In *The Scarlet Bullet*, he participates in cases linked to the WSG event and Hyperlinear train, though Conan and Masumi Sera drive the primary resolution. His role remains consistent—present at crime scenes but peripheral to solving central mysteries. Kogoro’s narrative journey contrasts comedic ineptitude with latent competence, activated by personal stakes or emotional ties. His dynamics with Conan and Eri, alongside sporadic genuine triumphs, peel back layers of his caricatured exterior to reveal a nuanced investigator shaped by unresolved relationships and hidden dedication.
