There is a legend among children that at midnight, someone with a grudge can access a web page called "Hell Communication". Type the name of the person with resentment on the page, and a "Hell Girl" named 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 the contract method and 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 will have to face the same fate after death... As for whether to untie the red thread, it is entirely the client's decision.
"If you harm others, you will harm yourself. When the other person goes to hell, your soul will also go to hell after you die. Even so, are you willing?"
