There is that trend in isekai for the reincarnator/transmigrator to just go through the plot as a normal resident of the world, with the knowledge from the previous world not coming in to play at all.
I guess it's because 'isekai' is hotter right now than just plain 'fantasy'.
This is alright, but it's less enjoyable than most of the villainess/otome ones. I think it's because the MC doesn't actually do anything; the plot just happens to her or around her.
