Something else I have read, which I am sure many don't know exist are the novels. The original story by Shoji Gatou. They aren't available domesticly yet. It really is a shame, they are sooo good. Better and more dramatic than the anime. There's this great web site called Boku Tachi that has been translating them. I highly suggest checking them out. They have stories that go beyond the events in "The Second Raid" and are even more exciting.
