I don’t think I have read any LNs with major twists so these are some more jokey ones. They may still be spoilers so continue with caution.
Ascendance of a Bookworm
- Rozemyne actually being a commoner called Myne
- Myne caring about something other than books
Didn’t I say to make my abilities average
- Mile has some common sense
So I’m a spider so what? (Actually contains spoilers)
- The demon Lord and the church are the good guys rather than the elves. (Or at least gooder?)
- White being a clone of Administrator D
I don’t remember seeing it either
