Hell Girl (Japanese: 地獄少女, Hepburn: Jigoku Shōjo), also known as Jigoku Shōjo: Girl from Hell, is a Japanese anime series conceptualized by Hiroshi Watanabe and produced by SKY Perfect Well Think, Tokyo MX, Wakasa Seikatsu, Fujishoji, Aniplex and Studio Deen.

It is directed by Watanabe and Takahiro Omori, with Kenichi Kanemaki handling series composition, Mariko Oka designing the characters and Yasuharu Takanashi, Hiromi Mizutani and Kenji Fujisawa composing the music.

It was broadcast across Japan on numerous television stations, including Animax, Tokyo MX, MBS and others, between October 2005 and April 2006.

In the fourth season, the story introduces a new character named Michiru, whom Ai helps realize her fate as a successor to the Hell Girl title.

Initially clients would write the names of whom they hated on an ema, which later changed to sending a letter to the address appearing in a three-column newspaper advertisement only visible to those with enough hatred.

Should someone submit the name of someone against whom they bear a grudge or immense hatred, and their request is accepted, Ai Enma will take them to a realm of perpetual twilight where she offers them a straw doll, which is one of her companions, with a red string wound around its neck and describe to the client the details of their contract.

Should the client pull the string tied around the doll's neck, Ai Enma will ferry the target of the revenge straightaway to Hell.
