Background / History

Mouri Kogoro is a former police detective who operates the Mouri Detective Agency. He lives and works with his daughter, Mouri Ran, while Conan Edogawa temporarily stays with them. His former colleague, Inspector Megure, continues to work with him on major cases. 7 20 43

During the art-museum murder case, Kogoro initially suspects Director Ochiai but doubts that an elderly man could physically carry out the killing. He shifts suspicion toward Kubota, though he ultimately recognizes that a conviction requires evidence rather than demeanor alone. 8 9

On Moon Shadow Island, he accepts an investigation request after learning it carries a 500,000-yen reward. Despite his initial skepticism of curses, he becomes increasingly serious as the case escalates from an eerie piano recording to Kawashima's disappearance, severed hands, and revelations about the Aso family's murder. 16 17 19 20

Personality

Kogoro is proud of his identity as the “Great Detective” and readily introduces himself with confidence, even when his reputation does not impress those around him. 17

He can appear unreliable: he drinks, sleeps at his desk, is easily distracted by attractive women, and sometimes dismisses Conan's deductions because of Conan's apparent age. 7 9 43

Beneath that behavior, Kogoro is practical and protective. He does not believe in supernatural explanations without evidence, notices the smell of blood in Kuroiwa's gift box, checks on unconscious officers, and becomes visibly angry when criminals endanger police personnel or evade responsibility. 16 19 21 23

Investigation
