The "Oh My Goddess!" universe is fashioned loosely around Celtic/Norse Mythology; various names and concepts are recycled for humor. Three worlds exist in the Universe of Oh My Goddess: Heaven, Hell, and Earth. Heaven is the realm of the All Mighty and goddesses, Hell is the realm of Hild and demons, and Earth is the realm of humans. Reality is controlled by an enormous and complex computer system, named Yggdrasil.
