Bureau of Exorcism, Case File Zero: Shadows of the Mountains and Seas

The passerby you brush shoulders with on the street, the smiling clerk in the coffee shop, the stranger who strikes up a conversation late at night: can you guarantee they're all human?

Bewitching female ghosts, bone demons impervious to blades and bullets, half-demons adrift in the mortal world, and strange spirits hidden among the common folk. They mingle with crowds and pass us every day, perfectly disguised. You can't see them or run into them, but that doesn't mean they don't exist.

The bustling city is nothing more than a hunting ground where humans, demons, ghosts, and monsters coexist. The next "person" who approaches you: are they human, or a hunter?
