After spending New Year's in Las Vegas (and attending a rather eye-opening poolside party at a fancy mansion), Yushi is fully relaxed and ready to continue his world trip with the Bookseller. Soon they're on their way to England, and a reunion with their old friend the Antiquary. Things quickly go awry, though, thanks to a coin Yushi happened to come across-and the moment Yushi finally finds Antiquary, he's instantly whisked away to a treasure hunt in the countryside!
