In a world where mysterious black marks appear on the skin of chosen hunters. The marks grant their bearers the ability to see, track, and fight spirits that hide between the living world and the shadows. Feared by both humans and ghosts, these marked hunters relentlessly pursue supernatural beings for money, revenge, or justice. As rumors spread of an unusually powerful ghost that refuses to disappear, hunters from across the land begin a dangerous chase, unaware that their target may hold the secret behind the marks themselves.
