Iwai Mushanokouji 武者小路祝
A girl with hair that cannot be cut. Her hair has never been cut since birth, so it is extremely long, and also grows fast. When Kiri found his ancestor's scissors, he was able to cut it, and he cuts it every time it grows (every day, due to to the curse). She is a shy and quiet girl, who has never attented school due her hair.
SpoilerHer ancestor, who was the first Hair Queen, left two curses behind before she died, the curse of the Killing Goods, and the cursed hair; the latter being the one Iwai carries. It is revealed that whoever kills Iwai, will have his/her wish granted, no matter what it is - and their curse will be lifted as well.
