It's just clickbait titles, because it works. Wouldn't surprise me if we see more of that on books as well in the future rather than short and vague titles
This fashion was not uncommon before the 20th century or so.
For example, Daniel Defoe’s seminal work from 1719: The Life and Strange Surprizing Adventures of Robinson Crusoe, of York, Mariner: Who lived Eight and Twenty Years, all alone in an un-inhabited Island on the Coast of America, near the Mouth of the Great River of Oroonoque; Having been cast on Shore by Shipwreck, wherein all the Men perished but himself. With An Account how he was at last as strangely deliver’d by Pyrates. Written by Himself.
And well-known enough for Monty Python to make a joke of it
> Yes...I wonder if you might have 'The Amazing Adventures of Captain Gladys Stoutpamphlet and her Intrepid Spaniel Stig Amongst the Giant Pygmies of Beckles'...volume eight.
In manga aren't click bait titles, but because there are so many published, you pick basically a title that explains the premise, otherwise it's harder to get users to read your manga. I suppose that also could work with novels, I'm not a book person, but I suppose you read a review or watched some video that recommended you a book, and if the title is self descriptive, then would easier to go to the book store and buy something that might is your liking.
