That’s not true, the lore for the entries never explicitly state that what existed before was one entire universe. However in an interview, Kamiya states that what you’re fighting Jubileus in,
is what the original state of chaos was. Meaning that giant sphere, is what existed, not an entire universe. This backs up her sitting at the apex, which is what her lore description says.
The Bayonetta universe we know, wasn’t the result of one big universe splitting into pieces. Which makes any sort of statement about paradiso being larger, very consistent.
Here kamiya talks about the time axes,
and how balders plan created a parallel universe with a separate timeline.
With that out of the way, it’s still vital to realize that these universes will be converged into one singular universe by Jubileus. This is a 2-C low multiversal feat.
Her weakened state needs to be changed from planetary, to universal. One of kamiya workers states that the dimensions
she creates are actually universes, and that the lava and ice levels are representations of
heaven and earth being created. Kamiya agrees with all this.
Because of this, any user with one eye should very well be universal. Jubileus draws her power from the eyes, and will only be completed when she has both. Meaning Bayonetta and Balder powered by the eyes should be changed from 4-C, to 3-a. And Jubileus weakened state should be changed from High 4-C to 3-A.
Queen Sheba receives the same 4-C to 3-A upgrade, while also making her 3-A full powered form into 2-C.
Aesir when powered by the right eye needs to be upgraded to 3-A, and his full power should be 2-C as they’re all comparable.
