There is a difference between Hyperbole and NLF.
Hyperboles do exist inherently in stories, because they are actual literary technique used in literature to exaggerate something. However, none of what is in these scans are hyperboles at all. They are direct, narrative statements meant to be taken literally.
NLF is a fallacy that people use to argue against people who wank statements or feats to their highest interpretation. NLF statements do not exist inherently in a story. It isn't a literary technique or anything, it's a argumentative fallacy.
Saying that the statements in these scans are inherently invoking no-limits-fallacy is insane.
One again, Dread.
If the sword has effortlessly destroyed everything it's tried to destroy without any problems, then there is no anti feats against it being High 3-A.
What I'm saying is, even if there's no High 3-A feats, there's also no feats that actually debunk the High 3-A statements because it hasn't ever struggled to destroy anything it's been faced with.
