Netflix revealed during its Netflix Festival Japan 2021 event on Tuesday that it will stream the anime adaptations of two spinoffs of Gosho Aoyama’s Detective Conan manga — Mayuko Kanba’s Detective Conan: Hannin no Hanzawa-san (Detective Conan: The Culprit Hanzawa) manga and Takahiro Arai’s Detective Conan: Zero no Tea Time (Detective Conan: Zero’s Tea Time) manga.
Arai launched the ongoing Detective Conan: Zero no Tea Time manga in Weekly Shonen Sunday in May 2018.
