The cells of the human body never rest for too long; there's always something new to do and learn every day. At least, that's 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's 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's just another normal day for these hardworking cells!

This is my favorite anime. First of all, I would like to say a special thanks to the author of the story and the studio of this anime who has presented a very interesting anime.

Just like the previous season, this anime tells of the cells in the human body that are described as humans (to make it interesting) who struggle to eradicate and fight bacteria and viruses in the body. some viruses and bacteria that were not previously featured in this season. the most interesting is where there is a scene where the vaccine enters the body, which is closely related to the current pandemic ...

Mixed Feelings
After reintroducing myself back to the Cells at Work series with Code Black, I thought I'd take a crack at watching the second season to the first one which I rather liked. And after watching, I can only think of one word to describe this season: Unnecessary.

Not BAD, but I feel like this season didn't need to be made. A lot of the same issues are being dealt with as in past episodes with little variation to be seen. "Bump" is very similar to "Scrape Wound" from the first season, and "Dengue Fever" and "Mumps" feel like derivatives of varying parts from "Cedar Pollen Allergy." ...

Hataraku Saibou S2 is a mediocre followup to the surprise hit that was the first Hataraku Saibou. Even as a fan of the first season I didn't find myself liking much of S2's content as much as I did with the first season.

I chalk most of this due to a lack of focus with its topics and plot. While the first season followed an inexperienced worker around her first day at work, having the benefit of the audience resonating with her journey of discovery throughout the human body, the second season is a lot more unfocused and scatterbrained. For the most part, you follow ...
