Each episode of this anime contains a short story of a person, who is going through something or probably being tormented by someone to the point that he or she accesses the Hell Correspondence website and submits a request to get rid of the person. Ai Enma, the Hell Girl, appears, and presents a doll with a red string on its neck that can send the named antagonist to Hell. When the string is pulled, Ai and her companions then torment the antagonist and eventually ferries them to Hell. Moreover, a price has to pay by the one who pulls the string as well. Once he or she dies, he or she will have to go to the Hell as well. When the episode ends, we hear Ai Enma saying, "When one person is cursed, two graves are dug."
Ai Enma is my favorite character. She is a female kuudere and yet unlike other kuudere characters from the mainstream anime, she doesn't swore loyalty to any other main character. It has been more than a decade and she still remains my most favorite female anime character. The anime has a good storyline for sure but Ai Enma's backstory and a triggered point where she goes against the authority and takes a different decision have been executed really well. Each episode has an interesting yet a depressive case. It will be hard to feel satisfied with the ending yet you yourself wouldn't be able to think of a better ending.
This anime first came out during 2005 and the animation is fine. The character designs are impressive. The theme songs are fabulous as well and really suits the atmosphere of this anime. Overall, a decent watch. Totally recommended.
