Manako Yami

The Manako Yami (眼の闇蟲 Manako no Yami Mushi, lit. Eyeball Darkness Mushi) is a purple, centipede-like Mushi that eats the eyes of the host if the host keeps their eyes closed. The mushi causes the eyes to be very sensitive to light. The Manako Yami breed and grow much quicker in dark areas, so immediate treatment is necessary.

Weakness
Medicine can be used at an early stage (when the mushi first infests the eyes) to remove it.

If the condition is serious, the mushi must be drawn out by moonlight before it can be taken care of.
