Devil's Contract: Just a Fair Deal

Demons, a mysterious species that has existed since the first humans. It is often understood as an evil existence, but in fact... It is indeed the case. "You little human being, offer your soul and make a contract with me. I will allow you to take something away." "Then I want you... The contract in your hand." What a risk, I almost got the most useless thing. "When humans think about it, I laugh. Do mere humans want to make a contract with humans? That's fine, let me enjoy the Fool's performance."
