About the title
Yuma and his girlfriend Akina stumble upon the long-abandoned village of Inunaki, after which Akina becomes not herself, constantly humming some song, and eventually takes her own life. When Yuma decides to return to the cursed village, his younger brother Kota tags along, and both disappear without a trace. Their mother is hysterical, their father declares he no longer wants anything to do with their "tainted blood," and their sister Kanae, who has tried to ignore ghosts since childhood, will have to save her brothers and unravel the mystery of the mystical village of Inunaki.
