The art by Yasuhiro Fukuda is similar enough to the flagship line while also being distinct. The cells here are cuter, the violence that can get quite gory in the other series has been toned down, and the body seems appropriately smaller and less complex compared to the adult bodies that are the settings for Cells at Work! and Cells at Work: Code Black! The character’s expressions are often a bit more exaggerated, and that totally makes sense as these cells aren’t old enough yet to become jaded or bored.
Each of the organs is depicted differently. The placenta looks a bit like a large conference center that’s been decorated to look like a preschool. The mother’s adult red blood cells hand over oxygen and nutrients to the baby’s childish red blood cells through a series of windows that look like a bank teller’s station. Because the mother’s blood and the baby’s blood don’t intermingle, the placenta acts as a meeting ground for both bodies’ red blood cells to exchange oxygen and nutrients. The umbilical cord is a long, tall tunnel with linoleum tiles and muzak playing in the background. The lungs appear to be composed of a series of large geodesic domes connected to massive vents. The small intestine looks like a mix between an oil refinery and an assembly line at a food manufacturer. The stomach, when it is first shown, is a dry, empty wasteland. The brain is a mix of NASA’s mission control room and a children’s library filled with information from the genes.
The book is listed as 16+ on Kodansha’s website, but I think it would be appropriate for middle grade readers. There’s no talk of sex or conception, no nudity, and the violence is pretty tame. I think that this would be a great series to give to a young reader, especially one who is starting to learn about the human body. By giving the different cells distinct personalities, it makes it easier for readers to differentiate between white blood cells, red blood cells, etc. And there are also helpful tips throughout the book for expectant parents and caregivers. A preteen who’s about to become a big sibling would likely get a lot out of this book. Heck, I got a lot out of this book!
