Ragtime World is a world only visited in the Tsubasa Reservoir Chronicle anime.
Ragtime World is an old dirty city stuck in the middle of an economic depression. In both clothing and architecture it is very similar to that of New York and London during the Great Depression/Slump. It is difficult for everyone living there to find work, and many must us the Employment Center to find any kind of work at all. It is also a very dangerous city with mobs and crime running amuck.
