While it is a great read, I have to agree with
@stricken123 that the writer has no idea how modern technology works and the fact we don't see much character development from Mc. But saying that she just “conveniently remembers impossible shit” is kinda wrong cause there is an explanation for some of her knowledge.
First, the Mc is a history lover ( to the point of obsession may i say, she literally hangs flags and has models of swords and helmets in her room.) She have a vast knowledge of history. There also war from her sister, agriculture from her grandfather (a farmer) and many more from his acquaintance which include but not limited to mushroom scientist (her uncle), (from picture, chapter 8) doctor, hunter, forklift driver?, police officer, livestock breeder(Tanaka Mitsuo). There is also her uncle, Ashimitsu, who also has a vast knowledge about things like quantum physics, sambo…( according to the 4 books in pg.14,ch.29. The third one is a Lev Tolstoy book and the last one is properly a light novel) and according to her, I quote “ asking you is often faster than looking it up”. Which meant she just casually had a living breathing wikipedia next to her. The moment she meets him is the moment her knowledge stops being only on agriculture, forestry and fisheries, the thing she goes to school for, and to other areas like chemistry so that is why we see so many random things.
But seriously, who casually remembers how some random sweets are made and
the 44th verse of the 5th chapter of the gospel of Matthew. Even I think it's bullshit, did she just have a f-ing library in her brain or sth? THAT JUST OVER POWER AS F-.
( Sorry if this it long, i have problem with look too deep in to stuff)
