This is an excellent anime from every side you see it. It succeeds the prequel magnificently, and continues developing the story with the same fast-paced, suspense-loaded style of the first season. Music composition was great, just like the art style, which was very unique and stylish; looked simple yet it was highly detailed. The character development is outstanding; you get to know and understand how everyone, I mean EVERYONE, acts.
It's a must see; even if it's re-watch.
