This year's 23rd issue of Shogakukan's Weekly Shonen Sunday magazine announced on Wednesday that Gosho Aoyama's Detective Conan manga will take a four-issue break, from the 24th through 27th issues. Aoyama will conduct research during the hiatus.
Weekly Shonen Sunday previously noted that Meitantei Conan Zero no Tea Time (Detective Conan: Zero's Tea Time), the spinoff manga series by Takahiro Arai centering on the character Tōru Amuro, will have new chapters when the main Detective Conan manga is on hiatus, and will not publish chapters of the manga otherwise.
<!–The main manga series centers on Conan Edogawa, the alias of detective Shinichi Kudo, whose body shrunk after being poisoned at the beginning of the story. Together with detective Kogoro Mori and his daughter Ran, Conan helps the police solve difficult mysteries.
Detective Conan has been running since 1994, and in August 2017 it became the first Weekly Shonen Sunday series to publish its 1,000th chapter. The manga’s 95th compiled book volume shipped last October. The manga has spawned an ongoing television anime series and a yearly anime film series. The 22st film in the series, Detective Conan: Zero the Enforcer (Meitantei Conan Zero no Shikkōnin), opened on April 13 and became the highest-earning film in the franchise’s history. Aoyama’s various manga series have a combined 200 million copies in print worldwide.–>
