text: Yokohama Yokohama is the home city of Aya Fuse in Extras. The cities name is never mentioned in the book, but in early drafts when Hiro was the main character, he refers to the city as Yokohama. The city is not shown to have any rusty ruins near it, so it is presumed to be built over the remains of the modern-day city of Yokohama, since Aya describes her apartment in Shuffle Mansion as having a view of mountains and of a coast; modern day eastern Yokohama has a view of both. Also, the large mountain that Aya and the Sly Girls visit multiple times in the story is presumed to be Mount Fuji.
  Londinium
  Only mentioned once in Extras, when Tally says that metal has been disappearing from the rust ruins near the city. It is presumed that Londinium is built near or on the ruins of London.
  Prettytime Architecture
  New Pretty Town
  New Pretty Town is where all of the new pretties live. They are full of parks, mansions named after famous people from the Rusty Time, and amusements for New Pretties after they've become new pretties. In Tally's city, New Pretty Town is separated from the rest of the city by a river, and the bridges report people when they cross the bridge. The exception is an older bridge, which Tally uses to sneak across the river and gatecrash a party that Peris was attending. Later, Tally needs a diversion in the city, and she tells some uglies about the bridge.
