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!

Then we come to society. What makes a society even? The people. Humanity have transcended and evolved for generations and generations and will continue evolving like an endless cycle of life.
What does a human compose of? Cells, organs, organ system, tissues, atoms, molecules, ions and so on and so forth. This things, particularly the cells, are the ones that keeps on giving ...

Mixed Feelings
Hataraku Saibou or Cells at Work has been highly praised despite his lack of story and the lack of characters just because it's unique and innovative.
If Hataraku Saibou can do something is to show that originality is not a guarantee of a good anime.
The show lacks something that i still cannot precisely explain. After the initial shock you quickly realize that despite its originality this anime is incredibly generic (does that make sense? i dunno but thats how i felt while watching this).

Story: There is no story, this is kind of a simpsons slice of life where at the end of the day everything is ...

It’s almost impossible to ignore biology when it comes to the human body. Hataraku Saibou (Cells at Work!) has the confidence to be its own series. It’s like you take the cartoony Osmosis & Jones and turns it into an educational exploration. The human body is complex and that alone really made me wonder how this show could capture its magic.

I’d say making this show takes a creative mind and the audience should feel connected when watching this anime. Right from the start, the show reveals the human body and what it’s made up of which is essentially red blood cells. It takes place in ...
