|Technique Type||Hollow Technique|
Kūmon (空門, Air Gate) is a Hollow technique.
Hollows and Arrancar can use special spiritual pathways to travel between Hueco Mundo and the other realms. These are called Garganta. A Menos Grande can open a Garganta by tearing through the barriers between the realms, thus creating a spacial distortion which opens a pathway. Gillians typically use this method to travel to the Human World.
