Shogakukan is listing a 20th volume for Nao Maita’s Age 12 (12-Sai.) manga for release on July 1.
Age 12 inspired the 12-Sai: Chiccha na Mune no Tokimeki (Age 12: A Little Heart-Pounding) television anime in 2016, two original video anime series, and a live-action DVD special.
The manga won Best Children’s Manga at the 64th Shogakukan Manga Awards last year.
Maita launched the Junjō Girlfriend manga in Shogakukan’s Ciao Deluxe magazine in March 2019 and the Otona wa Wakattekurenai.
