Yeah, I made the comment before actually reading the full comic so I was just analyzing what I was given with the links. I made the "bruteforce" comment based on the first fight so yeah. My opinions on this hypothetical fight sort of changed after reading through the entire comic.
Anyways, the magic system. In her world, they can be elemental however the spells/techniques she uses are mostly non-elemental. They're not too reality-warping either but they can produce a lot of heat depending on the power of the attack.
I say her reaction speed is above human but I don't see her going FTL in a very long time in my story.
On the anti-blitz thing, I can't really explain too much cause that would spoil my story. But to summarize, if she was put on through too much stress and in mortal danger a certain thing happens. Let's say this event can bust a city.
A lot of what I'm explaining hasn't been uploaded and what's published isn't exactly that good for scaling her outer limit.
I will say that so far even in my scripts, no one has the ability to slice a human clean off from the bones. Although that could just be because I'm writing a 13+ story.
