Universal govern more probably. I don't know much about it but I know the universe is apparently divided in four sections that fit with the cardinal points. For example, our Earth is placed in the North Galaxy, but it seems they use 'galaxy' differently than us, as in a wider meaning. What we consider a galaxy is just a small part of a real galaxy for them.

The North Galaxy is watched over by North Kai, who is basically the god of the whole galaxy and thus is above Earth's god. And apparently there's even another deity above him but I'm not sure.

[Maybe she should ask Goku a bit more about the future.]
