Kanyou Shoujo

Dolls are living plant life forms that look like beautiful women which can be purchased at a special shop for the right price. But be careful what you wish for. Set in an upside-down world combining a murky mix of science fiction, reality and moral ambiguity, Yumiko Kawahara's short stories examine the ineffable disparities that exist between the lover and the loved one.
