For anyone who might be interested in a top-level view of how Sato is adapting the Miniskirt Space Pirates novels for anime, here are the chapter titles of the first two books, along with the volume titles of all seven.
Mild spoiler potential, of course. If they keep the current pace, I’d expect book 2 to take the series up to around episode 9.

I know from Wikipedia Japan that books 4-6 are one big story arc, so that’s where I expect the series to end. That gives them a bit over 4 episodes per book, which is not unreasonable. It’s a comfortable pace to tell the story without having to carefully prune (AsoIku) or risk incoherency (Daimaou).
