>>55356828It's sort of implied Mumei is in the council as a safety measure because the gods weren't expecting for humans to manifest some sort of combined power, that may be some headcanon thought, council as a whole is mostly some sort of enforcement measure, they aren't a god class technically, as there would be actual gods somewhere, but I guess they'd be the god class relative to everyone else. Sana, Kronii, and Fauna were all made by the gods and are all fairly old, but Bae was recruited instead, and Mumei just manifested from the combined power of humanity. What I mean is that council wouldn't really be a god class, and they are separate from the actual gods in their canon.
The ones who imprisoned advent are stated to be these previously mentioned gods, not council. What these gods are or what they do is never mentioned thought
