耳虫
みみむし

Translation: ear worm
Habitat: the ears and heart

Appearance: Mimimushi is an infectious yōkai with long ears and a spotted, snake-like body. It writhes and slithers back and forth as it migrates between the ears and the heart, causing discomfort in its host.

Interactions: People infected with mimimushi crave cold foods and avoid hot food. Their stomachs appear swollen and bloated. Infections can be treated with remedies made from the herb byakujutsu (Atractylodes japonica) and the mushroom bukuryō (Poria cocos).
