Kyu has a masculine appearance. She has shoulder-length black hair and wears a white Kitsune mask. She is seen wearing a black suit with a white buttoned up shirt, a black tie, black pants and shoes. Her true appearance is currently unknown.
Given how she killed Mrs. Suirenji, she appears to be able to chop people in half with her hand.
She's first seen during the Administrators' meeting. She was later sent to assasinate Kiyoharu's mother, which she did by chopping her in half. Kiyoharu was able to detect her death via her Stick and asked Aya to do someting about it. Aya stole Alice's Stick and rewinded time. She then transported Kiyoharu to her home so she could save her mother. Kyu is then seen manifesting inside the Suirenji home via television screen, puzzled at how there's nobody home. She's later seen with the other Administrators once the King awakens.
- Her name means "Nine".
- Her face/mask is based on the Kitsune, a mask of a fox.
