I mean going from no sword skills to god tier in 0.1 seconds has to be exhausting. Like her mind knows what to do but her body isn't trained to do it... so there's a disconnect he's controlling it so her psychical limits are turned off until they slam her in the face all at once when he releases control. Plus after defeating presumably hundreds of soldiers if any of those guys calls her weak... they'll be having words from a fist.
I do get what you're saying though because it's a trope... but I think this is one of the only times I've thought yeah makes sense to faint male or female
If only she fainted after getting back to her tent or something, why she gotta look so shady and kinda weak
