Shiroi-kami no Musume

Presumed to be somewhere between fourteen and sixteen years old. Her birthplace is unknown.

She has snow-white hair, ruby-red eyes, and abnormally pale skin, giving her an otherworldly beauty that many find disturbing. She is also hypersensitive to sunlight, which forces her to remain indoors much of the time—much to her dismay. Though reticent and passive, she also has an air of femininity about her.

One stormy night, the White-Haired Girl shows up unannounced at the Rhodes household. She is taken in as a servant, but it appears she may have come for more than just work.

"This rose... This rose was white. Until I took it in my hand..."
"Then see for yourself... feel for yourself... that there is but one difference between us."
"Those memories give me the will to wait... for the day things go back to the way they were."
