Legend has it that at exactly midnight in the middle of the night, someone with a grudge can access a web page called "Hell Communication." Type the name of the person with resentment on the web page, and the "Hell Girl" claiming to be Enma Ai will appear next to the person with resentment. Hell Girl will then give the other party a scarecrow with a red thread tied around its neck, and explain how to make the contract and its consequences: as long as the red thread is untied, the contract will be established, and Hell Girl will exile the person the other party hates to hell. However, the other party also has to pay a price after relieving the resentment. The other party decided to exile the cursed person to hell, and he would have to face the same fate after death... As for whether to untie the red thread, it completely depends on the client's decision.
"When you harm others, you harm yourself. When the other person goes to hell, your soul will also go to hell after you die. Even so, are you willing?"
