Henrietta is a young girl who works for a "welfare group" that does the government's dirty work. Cybernetically-enhanced and specially-trained, she is one of a group of elite hit-girls, remorseless killers with no memories of their past. Jose, her partner, has taken care of her since she was brought into the organization following the murder of her family, and struggles between his affection for her, and his opposing duty to his employer. But, time is running out.. for with each bullet they fire, Henrietta and the other girls lose a little more of their humanity.
There are two main themes that run throughout both Gunslinger Girl and Jigoku Shoujo (Hell Girl) that make an appreciation of one lead into the other. Those two themes are loss of innocence, and retribution (whether it be divine or mortal). While Jigoku Shoujo is decidedly more canted towards spiritual retribution and Gunslinger Girl towards the hubris of man, both stories center around a young girl who, with a cast of adults who support her, carry out a certain final justice. What makes these two titles particularly compatible is that both are seeped in a dark sense of style, with a slow yet satisfying pace designed to keep you guessing what will happen next.
While Gyo is more so an adult adaptation of horror there are a lot of things similar between Gyo and Hell Girl. The idea of people get what's coming to them, the whole atmosphere and even the art style. Both are horror stories as well.
Thinking of committing fraud? Embezzlement? Murder? Think again. Though crimes often slip through the cracks of the laws of man, the laws of the spirit world are not as forgiving. In the underworld, even the dead can request vengeance against those who have wronged them, at the hands of the Judge, the keeper of justice. Hot on the trails of a corrupt executive, the Judge realizes that the chain-of-command might be guilty as well, causing an investigation of deadly proportions...
Both Judge and Hell Girl delve into the topics of supernatural justice/revenge. A theme they both use heavily is the concept of not being able to escape one's sins.
Hell Girl is longer, and thus has time to develop a fuller story, but I am confident if you enjoyed one, you will like the other.
Near the ruins of an old and abandoned city, there is played a game simply known as "Otokoyo." It is said that when children play this game, they go missing one by one. Some say it is ghosts. Others say it is demons. But for Hikora, one thing is certain: his sister disappeared playing the game and he will do whatever it takes to find her, even if it means playing the game himself. He and seven others will do just that, all for their own reasons, and learn that rumors aren’t always fictitious. Escaping with their lives will become the main concern when this game of hide-and-seek turns deadly.
As far as dark anime go, Hell Girl and Kakurenbo fit the bill. Hell Girl is a mind-blowing series and seems to share a few of its intense qualities with Kakurenbo. Both are suspenseful and thought-provoking.
Both Hell Girl and Garden of Sinners deal with the dark side of life, with horror and afterlife, with the consequences of actions taken earlier in life. Hell Girl is more episodic in nature, while Garden of Sinners (set up as a series of movies) has a more connected, plot-driven storyline, but both anime have a paranormal theme with a sinister vibe.
