It takes 90% of the book to meander over trivial daily life stuff with very little actual plot going on then just dumps it all right at the end of the book. With literal info dumping in the last few pages.
The characters are typical and stale and of course all the women are put into their places if they aren't meek to begin with. How many times does Emilia fall down, trip or is otherwise rendered helpless, then further embarrassed and humiliated. A lot.
The final ending is just garbage with Lucifer and really it just seemed pointless and not very funny at all.
