Cells at Work!
はたらく細胞

Summary

Inside the human body, there are around thirty-seven billion cells, who diligently carry out their duties every day. New to her job, clumsy but cheerful Sekkekkyuu AE3803 is excited to start delivering oxygen and collecting carbon dioxide despite her poor sense of direction. Meanwhile, Hakkekkyuu U-1146 is always ready to fight and kill any pathogen that he comes across. After running into each other multiple times, they quickly become good friends, regardless of their contrasting personalities.

Entertaining and educational, Hataraku Saibou follows the two blood cells and their many comrades as they work together to keep the body healthy.

Summary

Here comes a new Cells at Work! spinoff series—with laughs galore! Erythroblasts are cells raised by a Macrophage in order to become promising Red Blood Cells, but that doesn't seem to be really the case here with these erythroblasts, who are on an indefinite moratorium—with no reason to work!

Cells at Work! CODE BLACK
はたらく細胞BLACK

Summary

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, Sekkekkyuu AA2153 has to quickly learn to deliver oxygen and collect carbon dioxide, even in dangerous conditions. Meanwhile, Hakkekkyuu 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.

Hataraku Saibou Black takes a different approach by showing the grittier side of the jobs our cells perform.

Cells at Work!
はたらく細胞

Summary

Inside the human body, roughly 37.2 trillion cells work energetically 24 hours a day and 365 days a year. Fresh out of training, the cheerful and somewhat airheaded Sekkekkyuu AE3803 is ready to take on the ever-so-important task of transporting oxygen. As usual, Hakkekkyuu U-1146 is hard at work patrolling and eliminating foreign bacteria seeking to make the body their new lair. Elsewhere, little platelets are lining up for a new construction project.

Dealing with wounds and allergies, getting lost on the way to the lungs, and bickering with similar cell types, the daily lives of cells are always hectic as they work together to keep the body healthy!

Cells at Work!! The Return of the Strongest Enemy. A Huge Uproar in the Body’s Bowels!
『はたらく細胞!!』最強の敵、再び。体の中は“腸”大騒ぎ！

Summary

Ippan Saibou is envious of the public praise immune system cells like white blood cells receive for protecting the human body from deadly pathogens. Instead of watching safely from his home, he also wants to be useful and get recognized for his efforts. He soon comes across a group of infantile-looking bacteria getting washed away by a river current. Despite knowing the potential dangers that they hold, he rescues the bacteria and brings them to safety. However, Hakkekkyuu U-1146 picks up the presence of these bacteria and is on the hunt for them.

Meanwhile, somewhere else in the human body is NK Saibou, who is on the lookout for someone. Based on her intel, he is an antigen that the immune system cells have previously encountered, and he may have returned for revenge.

Cells at Work!!
はたらく細胞!!

Summary

The cells of the human body never rest for too long; there is always something new to do and learn every day. At least, that is what Hakkekkyuu U-1146 feels as he rushes to and fro, searching for any pathogens that could cause harm to the body. Despite his dangerous line of work, it is all worth it to protect the happy smiles of Sekkekkyuu AE3803, the platelet crew, his fellow neutrophils, and the other cells he meets along the way.

In his latest pathogen-hunting adventures, Hakkekkyuu U-1146 discovers how important cells can sometimes make mistakes, and that not all bacteria are actually bad. Everybody has their bad days, but everything eventually works out when their comrades have their backs. In the end, it is just another normal day for these hardworking cells!

Summary

Due to poor lifestyle choices, a certain human's body is in constant turmoil. With germs, bacteria, and foreign substances abound, the jobs of various cells become increasingly difficult and dangerous. As some of the unfortunate ones who matured in this chaotic environment, Sekkekkyuu AA2153 and Hakkekkyuu U-1196 strive to fulfill their duties—even if it means seeing many of their fellow cells lose their lives in duty.

However, the human’s condition continues to deteriorate, and whether or not these efforts will amount to something concrete depends on the cells!
