The first official spin-off of the July 2018 TV anime "Cells at Work"! The main characters are the "bacteria" that exist within everyone's body! Farts, constipation, silky hair, cavities... For all of these, there were good bacteria, bad bacteria, and bacteria that read the air... the earnest and hardworking "activities" of the bacteria working hard inside your body! Packed with knowledge useful for beauty and health! The much-talked-about "bacteria" anthropomorphic manga! There is some yellowing due to aging. There is a wrinkle on the inside of the cover of the first volume, so please check the second image.
