Hueco Mundo ("Wekomundo"; Spanish for "Hollow World", Japanese for "Hollow Sphere") is the dimension where Hollows and Arrancars usually reside.


Hueco Mundo is located between the World of the Living and the Soul Society, though it is separate from the bordering dimension known as the Precipice World. It can only be accessed by tearing the dimensional fabric separating the worlds, allowing Hollows to travel to any other dimension at will. Depending on the Hollow, the effect of this process varies. Regular Hollows usually appear from a small black vortex or form out of smoke, while Menos-class Hollows quite literally tear the sky apart to emerge. Arrancar use a more stable variant of the latter technique known as Garganta.

The landscape of Hueco Mundo is a seemingly never-ending white desert, with dunes like those of the Sahara. The desert is littered with what appear to be boulders and shriveled trees, but these are actually a form of quartz. In Hueco Mundo, the moon is on the opposite lunar phase of that in the Human World. The vast desert also seems to lack any bodies of water. Like in the Soul Society, the atmosphere is filled with Spiritual Power in the form of Reishi, but it is more concentrated, thus allowing smaller Hollows to gain nourishment despite the lack of Human souls.

Like that in real world deserts, active life in Hueco Mundo appears to be few and far between. Hollows generally seem to 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 Soul Reapers, all Hollows dwell in Hueco Mundo regardless of their shape, size, or power. Hollows can also drag other spirits into Hueco Mundo.
