Jigoku Shoujo (2006)

Both about a death girl who will help with revenge in exchange for the persons soul.

There is a rumour of a website called "Hell Correspondence", which only opens at twelve midnight sharp. When a user types the name of a person to be gotten rid of, a hell girl, Ai Enma, brings the person to hell. In return, the user will be sent down to hell at the end of his or her life.

A high school girl, Miho, is worried about her friend Haruka being trapped in the evil scheme of a popular rock band after Haruka joins the audition and starts acting strange. As Miho tries to help her friend, she finds herself in the cursed world behind the "Hell Correspondence".

High school student Watanuki Kimihiro has the ability to see spirits and monsters but is actually plagued with them. Coming home one day, he’s once again assailled by evil apparitions, but his feet lead him to a strange shop. There he encounters Ichihara Yuko, the mysterious owner who offers to grant Watanuki’s wish to be rid of the spirits. But the price must be of equal value, so Watanuki has to temporarily work for her in her shop that grants wishes. Thus begins his adventures in a world full of supernatural experiences.

Similar theme about people that have made a pact/are approaching their own demise. The story about the Death Girl.

Somewhere in the vast sea of the Internet, there's a website that can only be accessed at the stroke of midnight. Known as the Jigoku Tsushin, rumor has it that if you post a grudge there, the Jigoku Shoujo will appear and drag whoever torments you into the inferno. Very little is known about the girl - all we know for sure is that she lives with her equally enigmatic grandmother, that three magical straw dolls accompany and serve her, and that whenever a posting on the Jigoku Tsushin moves her, she becomes the Jigoku Shoujo.

A series where
- someone gives them (bad people) the same suffering they did from their victims
- they die after they receive the punishment
- the soul of the bad people receiving the punishment are going to hell

the differences are:
- In "Judge From Hell", a judge will convict you if you're good to go to hell.
while
- In "Jigoku Shoujo" there's a hotline/website called 'Hell Link' that you need to reach out to at 12mn, you need to type the name of the person who did you wrong and Ai will let you know if she accepts or rejects the human's revenge. The human will form a covenant with Ai (Hell Girl) by untying the scarlet thread from the straw doll's neck. There's also a consequence for humans who form a covenant with Hell Girl.

Both dramas are centered around female character who makes a revenge on bad people.

Jigoku Shoujo is more magic/mystery based while Girl from Nowhere is more psychological.

Synopsis
Have you heard of Hell Correspondence? Those with a powerful grudge may only access this mysterious website at midnight, allowing them to enter anyone's name and have that person be ferried straight to hell. Ai Enma, the Hell Girl, will not judge whether or not the chosen target deserves punishment; she will merely exact revenge on them for you. Not much is known about this young girl other than that she swiftly carries out her tasks with the help of three straw dolls. There is just one catch, however—as payment for carrying out such a request, the user must condemn themselves to an afterlife in hell.

Both are about an "revenge agency" of sorts, where a customer can make a deal to have revenge taken on someone who wronged them. One has more fantasy elements and comes with more consequences, but the topic is similar and both are episodic.
