Demon spirits make deals with people, granting any wish they desire in exchange for their souls.
The spirits thought no one would agree, but as it turns out, some people really are that foolish, and their wishes are all kinds of bizarre.
Some wish for love, some for selfish reasons, some for their children, and others to hurt people...
While helping people, one spirit also meets a very strange man. He seems to possess powerful magic, yet looks like an ordinary person. Sometimes, though, he can see through the disguises the spirit creates with magic.
The spirit repeatedly tries to uncover the man's true identity, but gets nowhere... Until much, much later, she learns that they must have known each other before...
