Hell Girl: The Sins of All Living Beings

My name is Ai Enma. You called for me, didn't you...? Take this. If you truly want revenge, just untie that red string. Once you untie it, you'll have entered into a contract with me. The person you resent will immediately fall into Hell.

But if you seek revenge, you'll have to pay a price too... Harm others, and you harm yourself. After you die, your soul will also fall into Hell. Unable to ascend to the Pure Land, your soul will wander in endless agony forever... But that's all after you die. Even so, are you willing to do it?
