Shinsei
The Shinsei world is the real world, it is our reality. It is the planet Terra and universe around it. It is very similar to the ninja world/dimension, but the differences are very significant. Everything that is possible in the ninja world such as jutsus, special powers and abnormal abilities are not possible in the Shinsei world. It is described as an extremely boring and mundane place. It's purpose isn't known and the Hokage 18 are often pondering why it exists. Shinsei is the old home of the Hokage 18 and some have returned home after fufilling their purpose in the ninja world.
