I was thinking about it too.
1 Joule is equal to 1 Newtonmeter, so for simplicity's sake, we will calculate the Work to carry a continent for 1 meter.
As far as I remember, to get the newtons, we have to multiply kgs by gravity's acceleration, so let's say 10.
Doing some not very precise calculations, for the continent of Australia, getting the info from google.
Surface: 7692 billion m2
Depth: I think 100km is a good depth, to keep the calculations simple.
Volume: Surface x Depth ~= 7 * 10^17
Density: Earth's density is 5515 kg/m3. I guess it's denser near the core but than the 100km depth I'm calculating but cba to research it further.
Weight of Australia = Volume x Density ~= 4 * 10 ^ 21
Work = Newton x Displacement, so 4e21 * 10 * 1 = 4e22 Joules
Finally, applying the conversion, we get 40000 Exajoules or 40 Zettajoules.
So if Kira can punch with the weight of Australia, she can also handle as much, at least while she punches.
With some more assumptions, the scenario becomes plausible.
1) Her hand may be able to withstand these forces when punching, but when attacked from the sides it may have a structural weakness.
2) Her arm was already strained by the speed which Eisheth jerked her into the ball's trajectory.
3) One thing I noticed about Superhuman/Monster bodies, is that once someone overcomes the "magical" protection, they go splat. So it's probably a mix of material and monster energy, with monster energy probably being the more prominent factor.
Possible errors in my calculations:
1) Perhaps the world of superhuman has even smaller continents.
2) Perhaps 100km depth is too much.
3) Perhaps calculating Work for 1m is too much. I'm really not that good at visualizing these effects so I can't tell, and I'd rather keep numbers as simple as possible.
All in all, I'd say the narrator is not too far off. Of course if we take it at face value, "into the exajoules" means a few tens or at most hundreds of exajoules, while my calculations reach thousands. going from 10*18 to 10^20 is quite a huge increase, but humans are incapable of visualizing these numbers anyway so I personally would excuse some imprecision there.
