This is an extremely popular manga series which required 10 editions in the shortest amount of time in the history of the publisher Kodansha. It has been announced that the manga is going to be adapted into a TV animation airing from April 2022, and the opening theme song will be Kiyoe Yoshioka’s “Dekoboko”.
