Spoiler: Manga Spoiler It essentially becomes Attack on Politics for a large part of the manga. There are a few good action scenes here and there but they're sparce and it focuses more on the mysteries given to us in the first season, while continuing to add more questions while dragging it out.
Easily anime > manga. Better pacing (at least for the first season), better art (the manga is atrocious), and the action scenes are exploited to the fullest with great animation. One of the few times where the adaptation is distinctly superior to the source material.
