NHK reported on Saturday that act-age story creator Tatsuya Matsuki (29) was arrested on suspicion of committing an indecent act with a female middle school student.
Matsuki and artist Shiro Usazaki launched the act-age manga in Weekly Shonen Jump in January 2018, and the manga is ongoing.
The manga was nominated for Kodansha’s 43rd annual Manga Awards last year, and is inspiring a stage play that will premiere in 2022.
The girl went to police, who analyzed security camera footage to investigate.
