Hell Girl (Jigoku Shōjo) is a Japanese dark fantasy anime series about a supernatural system that allows people to send their tormentors to hell via a mysterious website, Jigoku Tsūshin, accessible at midnight. The titular Hell Girl, Ai Enma, and her assistants appear to those who post a grudge, offering a straw doll with a red thread; untying it sends the target to hell, but the client is also sent to hell after death. The series explores themes of revenge, injustice, and human suffering through episodic stories, with later seasons introducing new characters and expanding on the lore.
