Detective Conan

## Detective Conan *Detective Conan* (also known as *Case Closed* in Western markets) by Gosho Aoyama is the longest-running mystery manga in history — serialized in *Weekly Shonen Sunday* since January 1994 and still ongoing in 2026 with over 110 volumes. It is the founding text of an entire multimedia franchise: one of the most watched anime series in Japan, an annual theatrical film tradition, and a global fandom. The franchise's detective-of-the-week format has created an accessible entry point for mystery readers of all ages, while the overarching Black Organization conspiracy serves as a three-decade long thriller narrative. **Shinichi Kudo** is a brilliant 17-year-old high school detective — already famous enough to regularly assist the Tokyo Metropolitan Police — who stumbles onto a suspicious deal by members of a shadowy criminal syndicate known as the **Black Organization**. Caught spying, he is forced to swallow an experimental poison called **APTX 4869**, which was designed to kill without leaving a trace. Instead of killing him, the drug has an unprecedented side effect: Shinichi's body is shrunk to that of a small child. Hiding his true identity to protect his childhood friend and love interest **Ran Mori** — and to investigate the Organization that poisoned him — Shinichi adopts the alias **Conan Edogawa** and moves in with Ran and her bumbling private detective father **Kogoro Mori**, whom Conan secretly puppeteers to solve cases. Each volume delivers intricate murder mysteries with satisfying solutions, while the meta-narrative of Shinichi's true identity and the Black Organization's schemes deepens across decades.
