A Hierarchical City (階層都市, Kaisō Toshi) is a term in BlazBlue used to describe cities that were built after the Dark War which left a large amount of hazardous seithr that covered the world. After the Dark War, a lot of humans and animals became tainted with the seithr and died off, save for the Kaka Clan. Humans were forced to move to high-altitude areas and create cities there.
