Random thought: Is the punchline of this series is gonna be that she is essentially a human equivalent of sacred beast (聖獣) but it's rude to attach that title to her, and since she's a girl, she'll get the Saintess (聖女) title instead...
Also, her having that sacred power might explains why she was heavily impacted by the noble society: Much like the beasts can see through people's true intention, she also could and that's why the noble society was even worse for her.
