Mayoi Hachikuji (八九寺 真宵, Hachikuji Mayoi) is the ghost of a fifth-grade elementary school girl who was killed in a traffic accident while trying to reach her mother's home. Since her death, she has been haunting people who possess an urge to avoid going home as an oddity.

Here is the skin of everyone's favourite finger-biter and wandering spirit.
For those who don't watch the show, she has a habit of biting the main character, Arargi.
