A very unique and educational anime ... to say the least, Cells at Work!
could very well wind up being shown in high schools and college intro to biology classes across the US and beyond.
Our protagonist is a cute, bumbling, endearing nameless red blood cell whom is referred simply as Red Blood Cell. It's basically a workplace comedy where the interior of a single, nameless human being is the setting and the city where everything takes place.
Kind of fun. Pretty funny. Very smart.
