Humanizing the microorganisms and cells of the body into characters just doing their job, laying out the arteries as highways, fat tissue as housing, and the body as a sprawling city of billions of regular workers. Plus, it's educational!
The concept itself isn't half bad, and I was excited to see what kinda story they would be able to make with this extremely unique setting.
The animation is nice, the music is upbeat, and the fight scenes are good, the two main characters are enjoyable, especially the red blood cell.
However, to my disappointment, the anime was unbelievably boring and the opposite of captivating. Why you may ask? Because it lacks an actual story.
The "story" is told episodically with each episode focusing on different parts, diseases or functions of the body. Laying out like a biology lesson, but with anime characters and their actions in the place of a textbook. This alone is fine, I don't mind being tricked into watching something educational however this heavy focus on being educational, and less focus on the main characters (who in many instances get little to no screentime in episodes or only appear by happenstance) leads to the anime only being a collection of various lessons with the minor subplot of the two "main" characters friendship/life in an attempt to pretend like there's actual plot progression going on.
The anime would have heavily benefited from focusing more on one main function or combating a specific disease within the body, or the struggles of the main characters in the taxing job of keeping the body operational, instead of various lessons with no connection to one another with the main characters only being used as vessels to explain body functions through their conversations.
I won't rate the anime too poorly as I understand what it was trying to do, and as a pure entertainment educational piece, it works very well. If you want to learn about the body in a more entertaining form than a textbook or you have a biology exam coming up I would highly recommend giving it a watch. However if like me, you expect a story you will sadly be disappointed as this anime is nothing more than biology class with more anime.
