Every soul has a plan. But if you stray from your destined path, your soul stone, called a psycholith, becomes tainted and shatters, bringing misfortune to all that encounter it. The mission of the uptight Sakurai and the freespirited Amano—agents of a company called Livingstone—is to find souls in danger of straying and keep them pure. If your life seems to be flying off the rails, and everything just seems wrong, you’d better hope this odd couple finds you in time to put events back on course—because if they’re too late, they might just have to help you along on your journey to the next life.
Amano has set out on a mission to find his soul, and along with Sakurai, his journey leads him to his hometown of Okinawa. As Amano seeks an answer to whether or not he can find his origins, Sakurai also seeks answers of his own. Heavy with the burden of reliving the memories of lost souls, he is haunted by the question of what exactly makes a soul. However, answering these questions entices danger, as Amano’s ever growing humanity has set him on a course for self-destruction. Will they find what they seek before it’s too late?
