Starts off a real 8/10 till around the late 30 chapters (When our protagonist is invited to the Castle). From here onwards however, I feel it just continues to get unneccesarily slow and then, even futher on, it gets unneccesarily convoluted. At this point the score continues to drop for me and by chapter 52 I feel like I'm reading a 4/10, hence my middle ground score of 6.

If you want to read, I would recommend stopping at 30 if you are fine without an ending or if you just want to slog through those most recent chapters.

For an isekai shounen it's definitely above average to start but it ends up dropping too far at the end, a real shame.
