u/kithas

Long time manga reader and this question may have already been answered, but, where does exactly the story takes place? Yeah, I know, "Hole". But is it a city that's part of a larger country? Is it also plagued by sorcerers? According to the story Hole is the place sorcerers go to have fun and to practice but why are they not expanding? Why nobody even thinks of moving out of the city where you are just target practice by dimensional psychopaths?

At least in the sorcerer world I get there are several more places but in general all locations in the manga feel hazy at best.
