Gorgeous Carat: Kurayami no Bitoku

Welcome to last XIX century in Paris, where ball gowns swirl, laughter rings through marble hallways, and jewels sparkle—both at the throats of the elite of the city, and in the amethyst eyes of one particular young man. A phantom thief is stalking the city, and nothing beautiful is safe from his clutches!

Meet Florian, the only son of an impoverished noble family who ends up indebted to the stunning, mysterious Ray Balzac Courland. He may have been sold to repay a family debt, but you can count on the fact that Ray is going to get a whole lot more than he bargained for!
