^ I think I should have put a line break or two in my original post... The church thing is just a pet peeve of mine that I already discussed elsewhere, while the manga went off the deep end the moment it had spent an entire chapter on the villain monologuing at the hero about how society has made them evil.
Because, what was the point of chapter 13, why was it in this story? First, we learn that the Princess is some kind of magical hacker who can trace magical cellphone jamming (which exists, just so) without any foreshadowing that she had ever specced into that build. So this half of the chapter introduces a new problem (jamming) in addition to the one already introduced last chapter (dragon), then immediately pull a solution for it of nowhere without any progress made on the dragon issue, then caps it off with a cool action scene. That's amateur fanfic-level writing, at best, and lazy delaying tactic, at worst.
Second, the Little Sister Archetype (LSA) calls the Heroine and tells her that her Respected Mentor Figure (RMF) who has so far given her zero reasons to doubt her trustworthiness is Actually Evil(tm). She offers zero proof or evidence, but that's OK, because the RMF takes one single look at the Heroine's face, immediately figures out what the LSA told her, and instead of making any attempt to salvage the situation or at least to stall her until the Earth Girl (EG) gets blanched, immediately goes "Muahahahaha, I am Actually Evil(tm)!". She then attacks the Heroine without provocation, reveals an incriminating location she was not supposed to know existed, confesses to every accusation, and then starts whining about how hard it is to have responsibilities in addition to all the perks and privileges of high status in the society. She then also tells the Heroine of her Special Destiny(tm) and, oh, just by the way, I killed your entire village, too, no hard feelings.
Now, just what is the Evil Old Lady's goal and motivation here? If she just wants the "blanching" ritual to succeed, why did she blow up a hole in the floor in the immediate vicinity. instead of using her official and personal pull with the Heroine to stall her? If she wants to gain the Heroine's sympathy with her sob story, then why confess to indirectly killing her parents and mock her for "not having a self" immediately thereafter? If she wants the Heroine to keep working for her out of her free will, why provoke and antagonize her? If she wants to brainwash her, why give the long-winded speech instead of just sucker-punching her while she's still confused? None of this makes the Evil Old Lady look like a competent and intelligent mastermind she supposedly is -- more like a entitled teenager throwing a tantrum.
A story is only as intelligent as its dumbest main villain, and this story's IQ has just dropped faster than Bitcoin after an Elon Musk tweet.
Well it's unfortunate that you dislike the series so much. Personally I'm still having fun with it. Your critiques are valid, but I was never taking this manga super seriously to begin with, so there was never a "off the deep end" point for me. I think it's just a fun little isekai adventure. That's all I can really say.
