Hi,
One of the first anime I read, its awesome I recommend it!
The story revolves around a girl named Ai Enma, who is better known as Jigoku Shoujo (Hell Girl). Her existence is known
only by a small group of people, and most of these people know her for the service that she provides, which is to carry
out grudges on behalf of the people who request her service by sending the person they hold a grudge against to
hell.
I didn't find the right solution from the Internet.
