The anime has a separate staff and cast from Cells at Work!! (with two exclamation points), the previously announced second anime season of Akane Shimizu’s Cells at Work! manga.
The manga and anime Cells at Work! showed you what happens when a young, healthy body gets in trouble… but what if the body wasn’t so young, and was never very healthy?
The second Cells at Work! anime season is also debuting in January 2021.
Shimizu launched the original Cells at Work! manga in the March 2015 issue of Kodansha’s Monthly Shonen Sirius, and Kodansha shipped the fifth compiled volume in Japan in August 2017.
