TRANSLATION: lung worm, lung bug
HABITAT: the lungs
APPEARANCE: Haimushi is a tiny moth-like creature with a segmented body and four wings.
INTERACTIONS: Haimushi infect the lungs and cause various health problems. They are fond of cooked rice. If a haimushi leaves its host, the person will die and the haimushi will transform into a hitodama—a fiery orb which floats about in the sky.
A haimushi infection can be treated with byakujutsu, a traditional remedy made by burning the powdered root of the herb Atractylodes japonica.
