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.
Sakurai and Amano continue their profession saving souls, but it seems to be having an affect on both of them. For Sakurai, constantly reading and reliving the traumatic experiences of the departed is taking a toll on his general well-being, but for Amano, the job is changing him in unexpected ways. These changes bring back lost memories of his previous life – memories that should no longer exist – and this starts Amano on a journey to find himself. For his brief existence, Amano has only known a life of saving souls, but perhaps now he can save his own lost soul.
