Cells at Work!
Volume 1


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.

Story: 9
The story mainly focuses on a red blood cell (Ae 3803) and a white blood cell (U-1146). They aren't given names, but numbers. The red blood cell has a hard time trying to find routes through the body, so the white blood cell helps her out. Through this, we get to know what exactly happens in different parts of the body and encounter different types of cells ...

Preliminary (25/30 eps)
This is one of the my most anticipated adaptation after reading it on a whim, an exceptional story about Cells, by turning them into characters, emphasizing the similarities of humans and cells through comparing them by how they do their job.

This manga is entertaining so far, for an author to be able to make great characters even if they are cells, an action packed story which centers around White Cell's adventures along with blood cell, this is truly one of the most interesting stories that I've ever read.

Story: 7
I don't think this manga was made for biology, anatomy or even medical students, this manga ...
