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...

A journalist rife with dirty dealing, a young girl isolated from the world. Vengeance from the past and vengeance blind to the truth, and a reporter who wants to stop the pointless deaths. All will come within Hell Girl's domain...

Once a mother's mistake, this time a sister's. Tragedy both past and present. As a reporter struggles to stay a step ahead and stop the vengeance, even he will need to be saved. All will come within Hell Girl's domain...

As vengeance loses meaning, perhaps it's best to put it all behind. But fate has other things in mind. Drawing the past into the future and the accused into the path of the damned, all will come within Hell Girl's domain...

Beyond the veil of midnight lies a mysterious website. Type in the name of one upon which you desire retribution... and it will be served. If you truly desire to take revenge upon those who have wronged you, just untie the scarlet thread from the totem's neck. Pulling this thread will bind you into a covenant with Ai Enma, who will ferry the soul of your tormentor straight into the depths of Hell. However, once vengeance has been served, you will have to deliver on your end of the bargain.

When you thirst for revenge, there's a surefire way to get it: simply go to the strange website that appears only at midnight, and enter the name of your enemy. The Hell Girl will appear to drag your tormentor to eternal damnation. But you will have to pay a price... your soul!

Revenge is sweet... and easy: just visit the Hell Girl's website, and this goddess of damnation will drag your enemy into the inferno. And some people will do anything for revenge. There's the girl whose best friend is scheming to steal her boyfriend... and the innocent student trapped by her unsavory employer in a haunted house. But they had better think twice - revenge may be sweet, but it isn't free!

Though someone has created a fake Hell Correspondence webpage, folks are still adding the names of school bullies and animal abusers to Ai's site - and she is dutifully ferrying the cursed to eternal torment. There's a catch, though: those who seek revenge (and Ai's services) must pay with their own souls... deliverable upon death!

This last collection reveals how Hone Onna was betrayed in love and follows the travails of Takuma, a boy accused of being a Devil Kid. Then the detective helping Takuma suddenly goes missing. Can Ai Enma, the Hell Girl, save them before it's too late?
