>>11882503Sana's officially stated size is almost 17million kilometer, which would look like that.
Since she never bothered to correct that scale, it's propably the most reasonable to assume that she can adjust her size to a lower degree even without the limiter.
Like I said, Yatagarasu is literally standard equipment for her so not including him only makes sense if you want to nerf her for a specific fight.
While you're right that it's impossible to quantify the power the ancient ones give to Sana, it's pretty much a given that it's considerable, the same applies to Ina, you wouldn't just scale her to be a regular human just because it's hard to quantify how much power she gets. Also the ancient ones are obviously a homage to the Cthulu Mythos and the fact that they still scale above Sana and the council means that it's fair to assume they just as powerful as they are in the original mythos (until proven otherwise).
Sana also has MFTL feat of traveling the universe to collect 50.000 of waterplanets + decently sized stars to make a suitable bath for her.
