Hell Girl

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. Of course, vengeance comes with a hefty price. Those who seek revenge must accept the fact that when they die, their souls will also be taken to hell.
