Dansai Bunri no Crime Edge

Kiri Haimura follows a rumor about a girl whose hair cannot be cut and meets Iwai, isolated by a hereditary curse. The scissors passed down in his family accomplish what ordinary blades cannot, giving her a chance to leave that confinement.

The same scissors connect Kiri to a deadly contest involving cursed possessions and their owners. With Iwai's life offered as the price of a granted wish, he chooses to protect her from people willing to turn their inherited weapons against her.
