You were just a child when you first started seeing Shinigami—supernatural beings whose duty is to collect the souls of the fallen. Once you reached adulthood, your rare talent got you scouted to work at a secret government agency monitoring their activity in Japan. Unfortunately, your office life consists of nothing but tedious paperwork and endless meetings… until one night, you come face-to-face with a ghost—a dangerous apparition that only appears if a soul isn't successfully retrieved.

Soon, reports of these hauntings come pouring in from across the country, and you're assigned to a secret task force with the three top Shinigami to investigate. As if that wasn't overwhelming enough, your heart stops when the agency director gives you some chilling news—your own soul is scheduled to be collected in just 30 days.
