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.

Ginko is on another adventure as he is brought to a very peculiar island, by a young boy Nagi. Ginko is taken to see a girl, who the island inhabitants refer to as "Ikigami" and is said to be able to perform miracles however Ginko discovers that there is more to this.

"All that is in my world... is seem sound taste and touch. That is all. That is enough..."

Finally able to reach a city, Ginko comes across a "biwa hoshi" named Amane, singing songs about Mushi and she is immediately able tell that he is a Mushi-shi. So she forces him to stay a night at an inn when she later reveals that she once saw a "Ganpuku" a very rare Mushi that will make the host see better and better until they die.
