A number of gemstones known as the Azuma Collection are being put up for auction.
The manager of the Ito Shobin Company hires Richard and Seigi to win a gemstone called the Buddha's Hand Citron.
During the pre-action preview, Seigi meets an acquaintance of Richard's named Shin.
It would seem that he is also attempting to buy the Buddha's Hand Citron, but how will the auction end...?
