Every twelve midnight you can access Jigoku Tsushin (Hell Hotline) online. If you type the name of someone you have a grudge against there, the Hell Girl will appear and she will introduce herself. She will also give you a straw doll which ties a red string around its neck. The rumors of the site became quite popular with children and students among the cities. However, you must make a contract with the Hell Girl before sending that person to hell.
