“Kuronekotei (黒猫亭) is a coffee shop that sits at the corner of the 5th district of the imperial capital. The girls who work there are autonomous mechanical dolls (automata) that were made by the most advanced technology.
The girls were created as weapons for the Great War years ago. But after the war, peace came to the city. Restored as new dolls, dressed in shiny kimonos, they look for the meaning of their birth.”
