The manga itself is a very refreshing change for the Shojo Beat line from Viz, as it's not focused on a typical girl meets boy romance. In fact, the author has said in the side notes that she wrote this title to be able to write a ghost story, not a romance story. This allows us to focus on the yokai themselves and their struggles. Natsume's grandmother, Reiko, has trapped them to a certain extent, and you feel bad for them even as you worry, as many of them are attempting to kill Natsume.
