The manga is a spinoff of Fumiya Sato, Yōzaburō Kanari, and Seimaru Amagi’s Kindaichi Case Files manga.
Amagi and Sato launched a new manga in January 2018 titled Kindaichi 37-sai no Jikenbo (The Case Files of 37-year-old Kindaichi).
Tetsuya Fujikawa, an editor for Kodansha’s Weekly Shōnen Magazine, stated on Twitter on Wednesday that Shinpei Funatsu will end the Kindaichi Shonen no Jikenbo Gaiden: Hannin-tachi no Jikenbo (Kindaichi Case Files Spinoff: Criminal Case Files) spinoff manga within the next month.
The original manga inspired other spinoff manga, anime movies, OVAs, and a television anime series.
