Cells at Work! Code Black

In this grim, mature spin-off of the Cells at Work! universe, the human body is a wrecked, unhealthy host, and its cellular workforce is pushed to the breaking point. Written by Shigemitsu Harada and drawn by Issei Hatsuyoshiya, this Kodansha USA series strips away the original's cheerful tone to explore the brutal, high-stakes reality of a body under constant assault from stress, STDs, and poor lifestyle choices. Over eight issues, readers follow a rookie Red Blood Cell as he navigates a minefield of exhaustion, infection, and moral compromise, offering a starkly compelling medical drama for adult readers.
