Your grievance shall be avenged.
According to rumor, a mysterious message board exists, accessible only at midnight. Those who find the site have the ability to post a grudge they harbor against someone, and the Jigoku Shojo (Hell Girl) will carry out the revenge and then transport that person's soul to hell.
