Hishaku, Hinoshu脾ノ聚
ひのしゅ

TRANSLATION: spleen shu (a type of infection)
HABITAT: the spleen

APPEARANCE: Hinoshu is a lumpy, rock-like microbial yōkai which infects the spleen.

INTERACTIONS: Hinoshu cause a lot of pain. When a hinoshu infection settles in, the victim feels as if they have fallen from a height onto an enormous boulder.

When an infection takes this form, it becomes very difficult to recover from this illness.  Traditionally, acupuncture is used to treat it.
