Hizō no kasamushi


Translation: capped spleen worm
Habitat: the spleen

Appearance: Hizō no kasamushi get their name from the bright red cap-like feature on top of their heads. They have a long, worm-like body covered in short red hairs, which ends in a hairy forked tail.

Interactions: The hizō no kasamushi’s cap interferes with the normal intake of food, so people infected with this worm become pale and weak. It can cause rapid weight loss as well as extreme weight gain.

This bug is very difficult to remove the from body, but its symptoms can be somewhat relieved by taking Chinese medicine made from agi (dried gum from the roots of ferula plants) and gajutsu (made from the stems and roots of turmeric plants).
