Brilliant, clever little show.
Just some friendly advice: When you watch it, make sure to watch the episodes in DVD order, not in aired order. Because the aired order was determined by fools, and the DVD order by the Mind Behind.
I guess I wanted to know more about the invasion. Like, what is its nature, and how do we fight it? But instead we're stuck with all these mostly annoying characters. The only one I like is the kinpachi, at least she's trying to figure out what happened. Also, where did that sheriff go?
