Author to conduct research during break
This year's 40th issue of Shogakukan's Weekly Shonen Sunday magazine announced on Wednesday that Gosho Aoyama's Detective Conan manga will take an 11-issue break, from the 41st through 51st issues. The manga will resume in the magazine's 52nd issue on November 27. Aoyama will conduct research during the hiatus.
The manga previously took a four-issue break in the magazine's 24th through 27th issues from May to June. It also previously took two other one-month breaks from January to February and in the magazine's 16th through 18th issues from March to April. Aoyama also conducted research during those three breaks.
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.
Arai (Tenshō no Quadrable, Cirque du Freak) launched the Meitantei Conan Zero no Tea Time manga in Weekly Shonen Sunday in May 2018. Aoyama has "complete supervision" over the work.
