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?
