The Back World (裏の世界 Ura no Sekai), also known as the Gangler's World (ギャングラーの世界 Gyangurā no Sekai), is a dimension, parallel to the Human World, where the Interdimensional Crime Group Gangler reside. It is where the Gangler Mansion is located.
A thousand year ago, Noel's species peacefully co-existed with the Ganglers and many other races in this world, but they were forced to flee to the human world after the Ganglers took over.
Gangler generals could freely open ripple-like portals to travels to Earth.
