Kaguya is on the multi-Continental level of power working her way to the small moon level power the sage at his peak was a Continental level power. Rai and his girls are at about large Island or small country level of power. They are all on the Tectonic scale of destruction level of power and Kaguya is about to step into the Planetary level of destruction power. At least that is how I would rate them. Rei and the girl might be at the country or large country level we haven’t seen them go all out in awhile so we don’t know for certain how high there power has gotten.
