The second DVD of this series (and the middle DVD since this is a short series of three DVDs) gets more into the lives and stories of the girls of the social welfare agency. We are introduced to two new girls of the agency and get more in to the story of the others.
If you are unfamiliar with the story of Gunslinger Girls, there is an agency in modern day Italy that takes in young girls that have had a traumatic event happen in their lives and are unable to cope with life in a normal way. The girls are implanted with cyborg parts and go through a very intensive training program that is referred to as "conditioning". Thes process erases their prior memory. Each girl is hand picked by a fratello, or "brother", that takes care of their every need and makes sure that they get the correct amount of conditioning. This is what makes up a majority of the Gunslinger Girl universe. The handler really controls everything the girls do and the they really have a special bond with them. Don't let this scare you off. This is not at all done in poor taste. The love between the girl and the handler is more of a brother/sister or father/daughter relationship.
I really enjoy the attention to detail that this series takes with the art direction and the gun detail. The music is also top notch. There is mostly classical type of music, but they also use music by the Delgados, which is awesome!
This disk gets more in to the "enemy" that they are facing, but the most of the story in the series still deals with the lives of the girls at the agency. This series gets away with the central "bad guy" type and goes more in to the lives of these girls and their handlers. If you can get past that, than you will really enjoy Gunslinger girls.
The extras on the disk include interviews with all of the voice actors for the girls. They are about five minutes each, and are very candid. There are also clean opening and closing credits as well as some special stuff on the animation of the characters.
Anyway, if you already bought the first DVD, chances are you are most likely going to purchase the second. If you haven't taken a look at this series, you won't go wrong with a great but short series.
