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!

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 ...

This show first attracted me because I thought it looked novel, and it was. For the first four episodes. After that I was really bored with this show. I couldn't sit through the show as the story repeated over and over with no effective change. The stories follow a certain format. Red Blood Cell finds either a germ, white blood cell, or a friend red blood cell and then they act afraid as the immune system fight the germs or that episode. The show failed to make me care about any of the characters. The art doesn't look back but it can be really ...
