It's curious how often this sort of a thing happens to me: you've got a main character that did not leave an impression when he originally showed up, but bring him back in a sequel series after a decade or two, and I get all excited.
This is a volume with a ton of twists, and the story gets much more complex. I have been annoyedfor the last several volumes about Sho’s plot, and she kind of gets written out here, which is bad. However, much of the rest of the story is awesome, especially as it links back to the past!
