It's boring. It's pretty much the same native reactions to modern techs as every other isekai with info dump about medieval Europe on top. The info dump is quite neat but feel tedious at time, should work as something for history class if you minimize the modern tech masturbation. Also, spreading another plague how ever mild Xiflu ends up being on top of the already overkill Black Plague? Really?
And the "witch"'s face remind me of a really shitty isekai.
