Alcohol, smoking, and stress—in the body subjected to these irritants, the cells responsible for maintaining life seem to fight a war that never ends. Due to a severe shortage of workers, Red Blood Cell AA2153 has to quickly learn to deliver oxygen and collect carbon dioxide, even in dangerous conditions. Meanwhile, White Blood Cell U-1196 has to do her part by dealing with germs and viruses during life-threatening situations. In the midst of these crises, they have to work together to keep the body healthy, despite not knowing if their sacrifices will be worthwhile. Cells at Work! Code Black takes a different approach by showing the grittier side of the jobs our cells perform.
Cells at Work! CODE BLACK is a darker take on the popular anime franchise, following Red Blood Cell AA2153 and White Blood Cell U-1196 as they battle to keep a body healthy despite constant assault from alcohol, smoking, and stress. This 2021 series shifts from the original's educational tone to explore the gritty, often losing war cells wage against disease and lifestyle damage. The show ran for one season and is now complete.
