Tonshi no kanmushi
頓死の肝虫

Translation: sudden death liver worm

Tonshi no kanmushi infects the liver (as do all kanmushi). It has a yellow body covered in black speckles, and at the end of its tail there is a white string-like appendage. The top of its head is black (which looks just like hair in the illustration, although the description of this worm doesn’t really go into further detail).

When a tonshi no kanmushi bites down on the liver, its host will die suddenly. Yikes!

Fortunately, it can be treated! Mokkō (Saussurea costus) is an effective cure.
