In a world where wealth can buy almost anything, people still must wait for vital organs. Raised to be harvested for body parts, Ray lost her sight before a renegade surgeon named Black Jack rescued her. Ten years later, she has become a surgeon herself, renowned for performing impossible operations thanks to the unique artificial eyes that replaced her own. Yet her surgical work is only a front for a larger quest: to uncover what became of the other children she was raised with, to locate the men who stole the eyes she was born with, and to bring them to justice.
