Humans have the Mortal World, monsters have the demon world, ghosts also have the Realm of Ghosts… it should've been like that.
But in this era, humans, monsters, and ghosts coexist—what humans don't know is that those creatures they think only exist in fantasy are right beside them… only because they're very good at hiding, and carefully obey certain rules.

Most monsters choose night shifts. Because there are relatively fewer humans working at night, the chance of exposure is lower; on the other hand, it also helps them absorb the essence of moonlight.
