Looks more to me that she just one-upped Youmu at swordsmanship (and apparently without a sword just to add more insult to injury) thanks to her stupidly overpowered sutra scrolls.
Her body-enhancing powers don't have any clearly defined limitations so it's generally assumed no physical task is impossible for her. Hijiri is essentially Touhou's Chuck Norris.
My body's strength is augmented by magic, so usually it's no greater than a regular human's, you know?Unless I open these magic sutra scrolls and activate their magic, I am but a weak being.Myouren Temple's chief monk looks more like a warrior than a magic user!Everyone said so!Just what kind of rumors...But, well, I've trained so I can open them instantly at any moment anyways.This person... is amazing...!!...May I ask for a duel?
