Hueco Mundo (虚圏 (ウェコムンド), Wekomundo; Spanish for "Hollow World", Japanese for "Hollow Sphere") is the dimension in which Hollows and Arrancar usually reside. It lies in between the Human World and Soul Society.


An unchanging night covers the sky, an endless white desert covers the ground. The tree-like objects are not plants, but rather quartz-like minerals.[1]

The landscape of Hueco Mundo is a seemingly never-ending white desert, with a multitude of dunes, littered with boulders. In Hueco Mundo, the moon is on the opposite lunar phase of that in the Human World. The vast desert seems to lack any bodies of water and contains rocky formations. Like in Soul Society, the atmosphere is filled with a high concentration of Reishi, thus allowing smaller Hollows to gain nourishment despite the lack of Human souls.[2]

Similar to the case of Human World deserts, active life in Hueco Mundo appears to be few and far between. Hollows generally dwell below the surface or in other areas until something provokes them to leave their shelter, like the intrusion of a foreign entity. According to the Shinigami, all Hollows dwell in Hueco Mundo regardless of their shape, size, or power.

Accessing Hueco Mundo[]

Hueco Mundo is located between the Human World and Soul Society, though it is separated from the bordering dimension known as the Dangai. It can be accessed by traversing the Garganta, a void between the worlds which can be crossed by Hollows, allowing them to travel to any other dimension at will.[3][4]


Hueco Mundo has no formal government. In Hueco Mundo, the strongest being wields power. If there is no particular leader or organization, Hueco Mundo runs as usual.
