Jigoku Shoujo Futakomori

Synopsis

Hotaru sends Takuma to Hell, insisting that this will all stop when Takuma dies. Ai begins to ferry a sobbing Takuma to Hell, knowing he has done nothing wrong. Reminded of her past, she turns the boat back, and reverts to her human self, gravely weakened. She now has no memory of her companions nor her time as Hell Girl. Takuma is almost killed by the townspeople until Ai intervenes. The mob ruthlessly beats her and Ai dies, saying "It's over." The Lord of Hell finally releases her parents' souls. The townspeople abandon Lovely Hills, and all charges against Takuma are dropped. Takuma's father also wakes up. At the end however, a girl is seen receiving a message from Hell Girl, saying her request has been accepted, meaning it's not over.
