名探偵コナン

名探偵コナン (known as Detective Conan and due to legal restrictions, known as "Case Closed" in English) is a 1996 Japanese anime. It is the 16th longest anime series to date, with over 900 episodes.

Shinichi Kudo (English name: Jimmy Kudo) is a high school detective who sometimes works with the police to solve cases. During an investigation, he is attacked by members of a crime syndicate known as the Black Organization. They force him to ingest an experimental poison, but instead of killing him, the poison transforms him into a child. Adopting the pseudonym Conan Edogawa and keeping his true identity a secret, Kudo lives with his childhood friend Ran Mori (Rachel Moore) and her father Kogoro Mori (Richard Moore), who is a private detective. Throughout the series, he tags along on Richard's cases, but when he is able to solve one, he uses a tranquilizer needle to put Richard to sleep, and impersonates his voice using a voice changer to reveal the solution to the case. He also enrolls in a local elementary school where he makes friends with a group of classmates who form their own Junior Detective club (Detective Boys). While he continues to dig deeper into the Black Organization, he frequently interacts with a variety of characters, including his professor friend Dr. Agasa, Ran's friend Sonoko Suzuki (Serena Sebastian), a fellow teenage detective Heiji Hattori (Harley Hartwell), various police detectives from different regions, and Kaito Kid (Phantom Thief).

Kudo later encounters an elementary school transfer student, Ai Haibara (Anita Hailey), who reveals herself to be the creator of the poison that shrunk him. She too had ingested the poison, but she is no longer affiliated with the Black Organization. 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.
