I'm a librarian who loves anime, manga, and reading a wide variety of genres.
(Slow going, slow going...)
I'm at the book's first battle scene (I assume there will be more). It should be awesome. Araragi's opponent is a vampire with super speed and arms that can transform into swords. Araragi discovered his regenerative powers when his arm was torn off, and his efforts to fight a vampire like the guy's a human have resulted in his hands being cut off.
So, technically lots of things going on. And yet Araragi's narration manages to make it all tedious. Why write a book in first-person when that person is boring and prone to pretentious mental rambling?
