This is pretty good. Playing with contemporary demonic tropes, has some iconic characters, sometimes funny, consistently novel.
If there's anything it's lacking, it would be, y'know, a plot.
It's an 8/10 for now, with room for improvement; the usual pattern is that the author after playing around for several years, thoroughly defining the characters and the world, actually has a semi-serious plot crystallize. Looking forward to that; a plot is such a good vehicle to take your jokes to the next level.
