In the 2/3 combined edition of Kodansha's Morning magazine in 2021, it was revealed that the spin-off manga written by Shigemitsu Harada and illustrated by Issei Hatsuyoshiya, Hataraku Saibou Black (Cells at Work! Code Black), will end with its eighth compilation volume, to be released in Japan on February 22, 2021.
This date does not mean that the work will be finished on that day, since the volumes may continue in publication even after the completion of the serialization of the work. So far there is no confirmed date of when the manga will actually end, however, it should be before February 22, 2021.
Harada and Hatsuyoshiya have been publishing the manga in Kodansha's Morning magazine since June 2018. The publisher published the sixth compilation volume on April 23rd, followed by the seventh on September 23rd. In addition, Akane Shimizu has been publishing the original manga Hataraku Saibou in Kodansha's Monthly Shonen Sirius magazine since March 2015.
The play is inspiring an anime adaptation produced by Liden Films Studios, under the direction of Hideyo Yamamoto and scripts written by Hayashi Mori, scheduled for release in January 2021.
Synopsis by Hataraku Saibou Black
The story focuses on a fledgling red blood cell, a member of the other 37 trillion cells in the body, but something is wrong! Stress hormones keep screaming at him to speed up the pace. Your blood vessels are covered with cholesterol. Ulcers, fatty liver, problems (ahem) down... It's hard for a cell to do its job when every day there is BLACK CODE!
Hataraku Saibou showed what happens inside a young and healthy body... but what if the body is not so young and was never very healthy? Hataraku Saibou BLACK tells the story of such a body, starring a red blood cell and a white blood cell, as they struggle to survive while doing their jobs inside a body that suffers from alcoholism, smoking, erectile dysfunction, athlete's foot, gout... literally a body horror. Whoever this guy is, he's lucky the cells can't go on strike!
