Echo Tokyo is the last bastion of humanity.
A nuclear fog has made street level uninhabitable.
Now hundreds of years later Echo Tokyo lives on, by building bridges and platforms between the skyscrapers to create a new city in the sky.
This cyber punk city somehow manages to function without government or law, where the companies rule and order is what people make it for themselves.
