On the outside Kiri is just some obnoxious boy with an odd obsession with cutting hair. It is something he has done ever since he was a kid with a pair of scissors that were handed down to him. Then one day he meets a young girl named Iwai who has long black perfect hair that he must cut. Only problem is that normal scissors do not cut her hair. However, for some reason his scissors do, that is because they are actually a cursed item called the killing goods.

Killing goods are handed down generation to generation by serial killers. They speak to their owners and compel them to kill other people. Kiri posses such an item and Iwai is the ultimate goal of the Killing goods, the Queen of Hair. It is said that if a killing goods kills her then the owner of the goods will have any wish granted. Kiri has just inherited the position of protecting Iwai. After all cutting her hair is the only way to keep his homicidal tendencies in check.
