This is definitely one of those experiences you will either love or hate. It is definitely satire.
The Art should always lend to the production and the design appears very purposefully American with a setting that is a parody of New York, it makes perfect sense. The art took some getting used and is probably the only reason this anime isn't better reviewed.
The Characters are all satirical parodies of real-life dynamics and remain a social dialogue about the bourgeoisie.
There were many interesting elements including the world in which demons exist but the main plot line doesn't seem to actually require them. The music was beautifully classic and lent itself to this darkly hidden subterfuge that maintained an aggressive presence in the undertone while making this ever prevalent facade.
To me the story doesn't appear to be about demons, it appears to be a youths experiences and growing up to see that everyone wears masks.
