Eikyuu Shoujo

"Silver" is a teenager living in Europe in the late 19th century, whose nickname comes from the strange color of her hair. Suffering from a mysterious illness, she has undergone numerous medical treatments paid for by her overworked mother, but Silver's condition has not improved. There is an old legend that speaks of the Devil who walks among the village in a handsome disguise, seducing young ladies so he can steal their time and live for eternity. In the villagers' eyes, Silver and her mother are the Devil's victims, and "Crow," a foreign bachelor who dresses all in black, is the Devil himself.

Silver is content to ignore these rumors, until one evening she witnesses her mother inexplicably crumble like sand at the hands of a hooded stranger, and soon after Silver loses consciousness. When she comes to, Crow is at her side, and he offers to take her away with him since she has no other relatives to care for her. They stay together until the early 20th century, and in that time, neither of them grow noticeably older. Silver comes to realize that they both cannot be human, but when did this transformation of hers occur?
