Jimmy Kudo, a 17-year-old high school prodigy and detective who frequently worked with the police, was attacked by two members of a mysterious crime syndicate while investigating a case regarding blackmail. He was then forced to take a newly developed experimental poison that was supposed to kill him, but due to a rare side-effect unknown to the two men, the drug transformed his body back into that of his seven-year-old self instead, after they left him for dead. In order to hide his identity and investigate the whereabouts of the syndicate, which he later finds out is called the Black Organization, he adopts the pseudonym Conan Edogawa. To search for leads to the syndicate, he manages to move in with his childhood friend Rachel Moore, whose father, Richard Moore, works as a private investigator. He also enrolls at Teitan elementary school and forms the Junior Detective League with three other children in his class; Amy Yoshida, Mitch Tsuburaya, and George Kojima. Even as Conan, Jimmy continues solving criminal cases, usually posing as Richard Moore with the help of special gadgets, invented by his neighboor and friend, Dr. Agasa. Richard Moore, a rather inept detective, is bewildered at the sudden rise in his case-solving abilities, but does not question this as he is more than glad about his subsequent rise in fame.
Later in the series, another main character, Anita Hailey, appears. A former member of the Black Organization, codenamed "Sherry", she is actually Shiho Miyano, a gifted chemist who developed the poison APTX 4869 which turned Jimmy back into a child. After her sister was brutally murdered by members of the Black Organization, she tried to get out and was held captive. She then attempted to commit suicide by taking a dose of APTX 4869, but instead was transformed into a child as well, and managed to escape from them. She then enrolled in Conan's school under the pseudonym Anita Hailey. She knows Conan's true identity and helps him in his quest to bring down the Black Organization.
Later on, Conan becomes involved with the American FBI, and they are able to capture Kir, a member of the Black Organization. Kir is later revealed to be an undercover CIA agent, and promises to relay information about the Black Organization to the FBI. They return Kir to the organization. Later, she tells the FBI that the Black Organization has a new member codenamed Bourbon.
