Appearing in the *Detective Conant: The Culprit Hanzawa* spin-off as a supporting character, Kogoro Mouri maintains his established traits from the main series, adapted to the spin-off's comedic and parodic tone. He continues operating as a private detective from the Mouri Detective Agency in Beika Town. His habit of frequenting bars leads to interactions with potentially dangerous individuals, exemplified when a shady bar owner attempts to exploit his drunken state. This peril escalates until his daughter Ran intervenes, demonstrating her protective role and Kogoro's recurring reliance on her in dangerous situations. The spin-off amplifies Beika Town into a crime-ridden environment where frequent murders and criminal activities are normalized. Against this backdrop of pervasive violence and societal desensitization, Kogoro pursues his detective work. Residents, including Inspector Megure, often joke about Kogoro and Conan attracting death, reinforcing the series' dark humor. His "Sleeping Detective" persona, solving cases while unconscious via Conan's deductions, remains an offscreen element of his reputation within this universe. His role remains consistent with the main series: a formerly skilled police marksman turned private detective, separated from his wife Eri Kisaki, and prone to unprofessional behaviors like heavy drinking, smoking, and flirtatiousness toward women. His serious deductive abilities surface primarily in cases involving his family. The spin-off utilizes these established traits for comedic effect without expanding his personal arc.
