It's more of a Gothic punk setting with various elements of cyberpunk given the technological advancements; that's its current era as those before it particularly the Old Ages were dark fantasy settings like Dark Souls, Berserk, and Bloodborne or just regular fantasy i.e. the Mythic Age as I call it, essentially Dungeons and Dragons.
Considering the amount of monsters that terrorize the world, humans corrupted by greed and pride, deranged cultists seeking to plunge the world into chaos, it's a decadent world. Not so much dystopian more like reminiscent of ours except much worse. Locked in a perpetual cycle of strife and conflict, whenever thwarted, invites newer challenges.
It's endured several ages of prosperity and darkness, going back and forth since humanity can't help themselves but be tempted by their vices and fixations for power and control. It also doesn't help that said vices are nurtured by malicious forces like vampires and demons who also infested mortal high society. Normal people try to live about their lives while those who are aware of the real world that being the world of gods and monsters are fighting tooth and nail to repel the darkness so these regular people can live their lives in peace or have some semblance of peace.
