If you have a grudge against someone, you can access the Hell Correspondence website at the stroke of midnight, type in your grudge's name, and the Hell Girl, Ai Enma, will appear to grant your wish. 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?

Second season of Jingju Mao.

Yuuki Akamatsu lives a normal high school life... that is until his cousin, Ayaka Nikaidou, convinces him to join the Journalism Club as a life consultant! His new job is to manage the advice column for the school's weekly newspaper to help him become more social. Soon, Yuuki is joined by three girls: the smart and shy Rino Endou, the athletic and outgoing Ikumi Suzuki, and the cultured and sweet Fumi Kujou. Together, they solve the personal problems of those who anonymously ask for advice. Although each of the new life consultants has their own unique perspective, they are able to reach solutions together by holding debates and social experiments throughout the week. However, as time goes on, the four slowly come to realize that they have not only been guiding other students through their troubles, but also working through problems of their own as well.
