Enma Ai seems like an ordinary girl, but in reality she is Jigoku Shoujo: Hell Girl. If you live in Japan and hate someone deep down, she will take revenge for you, at a price. Access her website at midnight and her services are yours, but in exchange you will spend an eternity in hell once you die. After the events with the reporter Shibata, Ai and her assistants Ichimoku Ren, Hone Onna and Wanyuudo are back to their duties of ferrying more souls to hell. Only this time, they are joined by a mysterious girl named Kikuri whose intentions and nature are completely unknown...
In the human world, there live demonic invaders named Shinma who prey upon the fragile souls of humans. The only hope for the humans is one of demonkind: Miyu, who is fated to destroy the Shinma and send them back to whence they came. Although half-human herself, as well as living amongst them as a typical high school student, she bears no compassion for those she saves, as well as condemns. Along with Larva, her subservient, Miyu sets out to destroy evil, one Shinma at a time.
The second season of Jigoku Shoujo retains the same dark and moody elements of the original JG even as it explores the interaction between Ai and those who seek her services. This forging of bonds between doomed supernatural females and humans is also very present in the latter episodes of Vampire Princess Miyu. Jigoku Shoujo Futamori reveals a deeper kinship between Ai and Miyu, firmly establishing them as kindred spirits.
The dark and brooding Ayakashi is composed of three horror stories: the narration of a young woman named Oiwa who was abandoned and betrayed by the one she truly loved, leading her to curse all who stood in her way; a story of two star-crossed lovers – a human and a forgotten god – and their struggle to have a future together; and the tale of an evil and malicious demon who is haunting and murdering a family for unknown purposes. Though different in animation style and tone, each story shares a similar theme: the darkness of the human heart.
