Hell Girl is an extremely formulaic and episodic series. It takes on a bit of a monster of the week format. The idea here being that shrouded in mystery and rumors a website becomes available for a single minute at exactly midnight. A link to hell in which you may enter a request for vengeance or help to be fulfilled. https://otakuusamagazine.com/wpcontent/uploads/2017/11/hellgirlscreen7.jpg This request is heard by Ai Enma Hell Girl as she investigates to understand the request and the parties involved. You learn the stories of the people sometimes devastating and other times selfish. For those that are deemed upon initial investigation to be worth the opportunity or more accurately the effort they are given a doll with a red string tied around its neck. As instructed by Ai Enma they may pull the red string and untie it if they find the complete resolve for their vengeance. If done the target will be sentenced to hell immediately. Though this comes at a cost as the person who placed the request will also be destined for eternal hell when they die. If the string is pulled Enma and a group of 3 other mysterious members of her group each with some pretty captivating personalities toy with and torment the target specifically subjecting them to guilt of their actions in an effort to coerce them into acknowledging their guilt and wrongdoings. Shortly after they are delivered to hell by Hell Girl/Ai Enma. While every episode seems to match this general format... I think each individual story although usually twisted in their own ways is interesting. More than that though there is continuous development given very naturally to Ai Enma herself as things seem to be a bit deeper than they initially let on with her as the Hell Girl at times expressing discontent with the role she is forced to play and the suffering involved. All of this handled in what is always a subtle way with a very particular atmosphere. A general calm that you can feel despite what at times are more horrifying events on screen or the melancholy and manipulation of others. Hard to quite put my finger on but I feel like the mystery of Ai Enma and who she is what she feels etc. is a super interesting background detail as it develops very slowly. I find it conceptually very interesting with the morals and themes of the anime that are explored. At times feeling a bit uncertain about the punishment of hell being given and the cost that is taken from the requester. At other times feeling satisfied with seeing the vengeance carried out but with a lingering uncertainty still due to the cost required to make that happen. A brief impact oftentimes shown to hint towards the varying path one might take and the affect knowing you are destined for hell may have on your life. Lots of interesting stuff that they work with and explore. Though the episodic pattern begins to become increasingly complicated as third parties become involved such as journalists or investigators attempting to dissuade others from committing themselves to hell and using the website. https://animemotivation.com/wpcontent/uploads/2019/09/aienmahellgirlwallpaper.jpg This series is definitely not going to be for everyone. But if you can stomach the slow burn and episodic nature of its first half Hell Girl is an unforgettable experience.
