Kiri Haimura is obsessed with beautiful hair, particularly hair cutting. This peculiar characteristic drives him to seek out a legendary long-haired ghost who resides in an abandoned house on a hill. However, instead of a ghost, he encounters Iwai Mushanokouji, the "Hair Queen," a lovely girl with long flowing hair whose hair cannot be trimmed due to a family curse. Iwai says that there is a death game going on around her, and that if she is slain by a cursed weapon, appropriately termed a "Killing Good," the bearer has their wish realized. After defending Iwai from "Authors"—Killing Goods users—he discovers that a Killing Good has been handed down in his family: a pair of scissors used by his ancestor to commit murder.
