MC claims she can use healing magic + healing magic is known to be an exclusive characteristic of the saintess = nobody asks her for a demonstration (which would provide undeniable proof), instead banishing her on the spot AND peppering the story with rape from the get-go?
In my experience, this is one of - if not the - shallowest start of a series. Full of clichés, not a speck of individuality, skimmed over, apparently treated with as much respect as the MC of the story.
