The official Twitter account for the anime of Keigo Maki‘s Shikimori’s Not Just a Cutie (Kawaii Dake Ja Nai Shikimori-san) manga announced on Wednesday that the manga will end with its 20th compiled book volume. The 20th compiled book volume will ship simultaneously with the manga’s 19th volume on April 7.
Kodansha USA Publishing is publishing the manga in English, and it describes the story:
Shikimori seems like the perfect girlfriend: cute, fun to be around, sweet when she wants to be… but she has a cool dark side that comes out under the right circumstances. And her boyfriend Izumi loves to be around when that happens! A fun and funny high school romance with a sassy twist perfect for fans of Nagatoro-san and Komi Can’t Communicate!
Maki launched the manga in Kodansha‘s Magazine Pocket manga service in February 2019. Kodansha published the manga’s 17th and 18th volumes simultaneously on Wednesday. Kodansha USA Publishing released the manga’s 11th volume in December 2022.
The manga inspired a television anime that premiered in April 2022. Crunchyroll streamed the anime as it aired in Japan.
