Neither good nor evil, they are life in its purest form. Vulgar and strange, they have inspired fear in humans since the dawn of time and have, over the ages, come to be known as "mushi." The stories of the Mushi and the people they affect are all linked together by a traveling Mushi-shi, or "Mushi Master," who seeks rare Mushi sightings and uses his shaman-like knowledge of Mushi to help the affected people.

Some live in the deep darkness behind your eyelids. Some eat silence. Some thoughtlessly kill. Some simply drive men mad. They are known as mushi—creatures that came into being shortly after life emerged from the primordial ooze. They still exist parallel to our own lives and can only be seen by a select few. As a mushishi, Ginko is one of the few who are aware of their existense, and this young man with a sardonic smile roams from place to place with the knowledge and skill to aid those unwittingly affected by mushi.
