Jimmy Kudo (Japanese name: Shinichi Kudo) is a high school detective who sometimes works with police to solve cases.[2] During an investigation, he is ambushed and incapacitated by a member of a crime syndicate known as theBlack Organization. In an attempt to murder the young detective, they force-feed him a dangerous experimental drug. However, instead of killing him, it shrinks his body to the size of an elementary school child.[3] Adopting the pseudonym Conan Edogawa and keeping his true identity a secret, Kudo lives with his childhood friendRachel Moore (Ran Mori) and her father,Richard (Kogoro Mori), who is a private detective. Throughout the series, he tags along on Richard's cases. Nonetheless, after Kudo solves one, he usesDr. Agasa's hidden tranquilizer to sedate Richard and then uses a voice changer to simulate his voice to reveal the solution.[4] He also enrolls in Teitan Elementary School, where he makes friends with a group of classmates who form their ownJunior Detective League (Detective Boys). While he continues to dig deeper into the Black Organization, he frequently interacts with other characters, including his neighbor, Dr. Agasa; Ran's friendSerena Sebastian (Sonoko Suzuki); a fellow teenage detective,Harley Hartwell (Heiji Hattori); assorted police detectives from different regions; and aphantom thief calledKaito Kid.
Kudo later encounters an elementary school transfer student,Anita Hailey (Ai Haibara), who reveals herself to be a former member of the Black Organization under the code name Sherry and the creator of the experimental drug that shrunk him. She too ingested it to evade the pursuit of the organization.[5] She soon joins the Junior Detectives. During a rare encounter with the Black Organization, Conan helps the FBI plant a CIA agent,Kir, inside the Black Organization as a spy.[6]
Case Closed was conceived in 1994 during the rise of mystery genremanga due to the publishing of the seriesThe Kindaichi Case Files; the first chapter appeared inShogakukan'sWeekly Shōnen Sunday on January 5.[7][8] Aoyama cites the stories ofArsène Lupin,Sherlock Holmes and the samurai films byAkira Kurosawa as influences on his work.[9] When scripting each chapter, he ensures the dialogue remains simple and spends an average of four hours for each new case and twelve for more complicated ones.[10][11] Aoyama's older brother is a scientist who helps him out with the "gimmicks" in the series.[12] Each case spans several chapters (except for a handful of shorter cases that span only one) and is resolved at the end, when characters explain the details of their solutions in simple terms.[13] An online database of all the cases from the manga was launched in 2007.[14][15] In 2007, Aoyama hinted that he had planned an ending but did not intend to end the series yet.[10] Aoyama and his staff decided to computerize their manga creation process in early 2011, although he still draws with a pen and paper.[16][17] The change began with the final page of chapter 760.[17]
