Mushi-Shi

Shinra, a boy living in a forest with mysterious powers, calls for Ginko, The Mushishi, to help him with his problems. While Ginko is staying with Shinra, he tells him all about Mushi and his powers. Later on, while walking in Shinra's house at night, Ginko finds a Mushi... But this isn't an ordinary Mushi, it's Shinra's grandmother!

A girl named Sui has an unusual disease that causes pain in her eyes whenever she sees light. She has to be locked in a pitch black shed that has no light in it. A boy named Biki helps Sui by removing bandages, giving her food, and just talking to her. Biki's mother is worried about him getting the illness, so she tells him not to stay as long as he normally would with Sui. One day while Biki is talking to her, she tells him why she has that illness: There are Mushi in her eyes. Biki continues to take care of her until one night when he is reading by a candle, a strange pain comes to his eyes.

On silent snowy nights, when no sounds can be heard, many people go deaf in one or both ears. The doctors can't do anything, so they think it might be paranormal. Ginko looks into some of the villager's ears and he tells them that the cause is a Mushi called "Un". After dealing with their small problems there is one more person who has lost sound in both of his ears and his condition is very different than the other people's, as he has also grown four horns on his head.
