The initial premise for this seemed promising... but holy crap it went downhill fast.
Is she trying to ruin the world she set up shop in? With the amount of plastic crap she is moving into this low-tech world, the whole country will look like a trash-heap from the discarded, unusable packaging and suchlike before too long. Her brief worries about the economy seem like wasted words with all the cultural damage she is doing... between the plastic and her little "consultation" displays I'm surprised they haven't burnt her for witchcraft yet (but unsurprisingly they all love her and let her get away with everything for some unfathomable reason).
That and the disjointed tatters trying to pass for a plot... I have to wonder whether this was just a really awful story in the first place or just a really patchy and poorly done adaptation of it? Heck, I've had to lower my standards a bit since I started reading Isekai stuff... but this really is the pits.
