Yura and Sumi, the former's caretaker, were close friends. Eventually, as they were moved apart, Yura could still feel Sumi's presence. However, whenever that happened, she'd become like an empty shell, worrying her father. As Ginko comes to know of the case, he proceeds to offer them advice, as the condition is caused by a mushi that can connect people's minds.

Shigeru's daughter (Yuri) is found dead in the mountains. A painful skin infection breaks out in his village. Ginko can cure the disease of the villagers but Shigeru has a much more serious case. It turns out that he and the son of his deceased brother brought back the mushi causing the problem to the village when they broke a taboo.
