The "Hell Communication" can only be accessed at midnight. If you write a letter of resentment and send it, the Hell Girl will appear and throw the person you hate into the abyss of hell. The rumors circulating on the streets are actually true. Her name is Yanma Ai. She is a girl who is not very eye-catching at ordinary times. Once she resonates with the feeling of hatred, she will transform into a Hell Girl. However, there is a contract with the girl that has not been mentioned in the legend: "Cursing others is double. When you send the other person to hell, your soul will also go to hell after death. Does it matter even if it is so?"
