Kiri Haimura

Kiri Haimura is a middle school boy who possesses a "Killing Good" inherited from his ancestor, which is a pair of scissors that are extremely sharp, and are the only things that can cut Iwai's hair. His ancestor was a murderer, who would bring people into his basement, and then cut them up with a pair of scissors.

He has a hair cutting fetish, which goes hand in hand with Iwai's predicament. He holds Iwai dear, and will do anything to protect her.
