BMBP is set on an alien planet, in a city that shifts and changes with every night. Within this city of skyscrapers and ancient structures, there are strange creatures who evolved complex sentience just to have to work a desk job. The sky is blanketed in a permanent gray, yet storms only occur when a tear exposes the ground to the eye of the red star. It's hard to say if the sky above, the land you stand on, or the reality around you doesn't host another being at any point. Angels exist, and demons (in some capacity), yet they lack a god to lead them; not to say that there isn't a god watching over them anyways. yeah thats like a quarter of whats happening, its a lot to try to summarize well.
