Demon souls trade with people and can help people realize all their wishes, but people have to pay the price for their souls.
The soul thought that no one would be willing, but the fact is: some people are really that stupid, and their wishes are also all kinds of strange.
Some do it for love, some do it for their own selfish desires, some do it for their children, and some do it to harm others...
In the process of helping others, Soul also met a very strange man. He seemed to have strong magic power, but he looked like an ordinary person, but he could sometimes see through Soul's disguise with magic.
The soul tried several times to know the man's true identity, but all failed... It was not until a long, long time later that she realized that they should have known each other before...
