In a post-nuclear war world, a brutal global Hide-and-Seek game has taken control. Countries select players to survive hunts in Instance dungeons; failure means territory occupied. Sage Lin, imprisoned for 15 years, is selected. She has the innate ability to see ghosts, thriving in Instances. Earning S-tier rewards, she forms an alliance with players from Southland, Bear Nation. They retrieve supplies and uncover a shocking secret: hunters are souls of deceased players.
