Hueco Mundo; Spanish for "Hollow World", Japanese for "Hollow Sphere" is the dimension where Hollows and Arrancar usually reside. It lies in between the world of the living and the Soul Society. Moderator:Kino M. Kyodo
Soul Society, literally "dead spirit world" is an afterlife (also called the spirit world). This is also where Shinigami live and is where most Souls dwell until they are reincarnated into the Human World. Moderator:Kino M. Kyodo
