Hell Girl: Fourth Twilight

"Hell Girl: Fourth Twilight" (also known as "Jigoku Shoujo: Yoi no Togi") is the fourth season of the "Hell Girl" anime series. Like its predecessors, the series revolves around the mysterious "Hell Correspondence" website that can only be accessed at midnight. Those who hold a grudge against others can enter their name on this website, and the Hell Girl, Ai Enma, will deliver that person to hell. However, requesting this service comes with a high cost: the requester is also destined to go to hell after the end of their life. "Fourth Twilight" follows the same episodic format with Ai Enma and her assistants delivering retribution on behalf of the vengeance-seekers. However, this season also includes a couple of episodes that delve into Ai Enma's past, revealing more about the mysterious Hell Girl and her tragic origin story.
