Demons walk among us, and it's our own fault.

For a down-on-their-luck human, visiting a Wish-Dealer demon is always an option. However, the wish may not be worth the price.

Mina needs money desperately. When she decides to barter her body for cash to a demon named Sebastian, she doesn't quite know what she's getting into.

Sebastian, the most renowned Wish-Dealer in the nation, does not trade sex for money. He's above such dealings, or so he thinks. But when the gorgeous and intriguing human named Mina shows up and offers herself? Well, that is a deal he can't find it in himself to refuse.
