The Severing Crime Edge - S01

Kiri Haimura has an obsession with beautiful hair, specifically, cutting it. This strange trait leads him to seek out a rumored long-haired ghost who supposedly lives in an abandoned house on a hill. But instead of a ghost, he finds a beautiful girl with long flowing hair named Iwai Mushanokouji, the "Hair Queen," whose hair cannot be cut because of a family curse. Iwai explains that a death game surrounds her, and that if she is killed by a cursed object, fittingly called a "Killing Good," the wielder gets their wish granted. After protecting Iwai from "Authors," the users of Killing Goods, he learns that his own family actually passed down a Killing Good: a pair of scissors his ancestor used to commit murders. Naming the scissors "The Severing Crime Edge," he discovers he can cut Iwai's cursed hair with them, freeing her to live a normal life. But many Authors want to kill the Hair Queen, and Kiri must protect her in this deadly game of fate.
