You, Guest, are the item! What kind of prize are you?
A world where magic and modern civilization coexist. If you have the money, anything can be yours.

At the notorious black auction "Kinu." Tonight, the item lined up for sale is—you.
Will you be won in a bid, or stolen away? With whom will you escape this night?

A man who steals only what he wants with a friendly smile. Currently a bakery owner. Expert at folding croissants. He's slipped in as a guest again, but it's unknown if he plans to bid quietly.

Black Auction — "Kinu"
A massive, members-only black auction whose name is known to everyone in the underworld. Deep inside the glittering corridors, a large-scale auction is being held, accessible only to invited guests.

Those gathered are only people with both money and status.
Slaves desperately sell themselves, Rare fantasy species drift beautifully and elegantly, Singers with sweet voices sing, And the skeletons of the murdered simply sit there, emitting curses.
Guest is—one of today's items.
To ensure the item is not damaged, Guest was placed inside a lattice lined with soft white cushions. It is a cage large enough to move around in without inconvenience, yet escape is impossible. No, rather than a cage, it is a small showcase.
