However, the price for ridding yourself of such a burden is a steep one: in return for condemning the soul of your tormentor to Hell, your soul will also face eternal damnation. In her long vigil as the Hell Girl, Ai has met many willing to pay such a cost. In Jigoku Shoujo: Yoi no Togi, Ai and her enigmatic companions continue to carry out their work, ferrying soul after suffering soul into the depths of Hell. However, as of late, a mysterious girl has been following them. This strange child, unable to even remember her own identity, questions Ai about her duty as the Hell Girl. Who is this girl, and what connection does she have to Ai?

It is said that if someone seeks revenge, they should dig two graves—and this is especially true of those who use the Hell Correspondence website. At the stroke of midnight, this ominous web domain becomes accessible, and whoever inputs the name of their grudge will get a visit from Ai Enma, the Hell Girl. Ai explains that she will send the target's soul to hell, but the requester will also end up in hell when they die. For some, that price is far too steep; for others, where they will spend their afterlife has no bearing on their current, day-to-day hell. But one thing is certain: the Hell Girl will always be available to those in need of revenge, while she stoically performs her duty of ferrying souls into the darkness.
