The Severing Crime Edge

Kiri Haimura's unique fixation on cutting hair leads him to an abandoned house on a hill, where he encounters Iwai Mushanokouji, known as the "Hair Queen," whose long hair is protected by a family curse. The "Hair Queen" explains that her life is in danger due to a death game involving "Authors," users of cursed objects called "Killing Goods." Kiri discovers that his family has a Killing Good, a pair of scissors used by a relative for murder, which he names "The Severing Crime Edge." He uses these scissors to cut Iwai's hair, freeing her from the curse, but now they must evade the Authors seeking to kill her.
