Some live in the deep darkness behind your eyelids. Some eat silence. Some thoughtlessly kill. Some simply drive men mad. They are known as mushicreatures 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.
They live on the shadowy border between the possible and the impossibleancient lifeforms known as mushi. Rare is the individual who can see them, but those with that special ability, the mushishi, can counter the creatures' deadly effects on humans. After a young boy is orphaned in the forest, he is saved by a reclusive female mushishi. But the lake near the mushishi's home holds a deadly secret, and the boy must find out what it is before his only friend is lost forever.
