gunslinger girl manga (spoilers)

[eva-boy7985]

Hey just curious, does anyone if there's any more gunslinger girl mangas planned beyond volume 3? While 3 did have some closure regarding the cases the agency was working on, there was practically nothing regarding any of the deeper elements such as Giuseppe (jose in the anime) and Henrietta's relationship or anything concerning the girls' battle with their own humanity versus their cybernetc "personalities". Thus far the anime has pretty much followed the manga verbatim; I enjoyed volume 3, but regarding the more foundational and deeper elements of the manga, it feels like nothing was really accomplished or discovered. I'm just curious, because honestly, I don't want the anime to end the same way. I'm all for abstract shows, and a lack of closure at times, as it leaves things open to the viewer's interpretation, making things more personal at times, but this was just flat out unsatisfying.
