posted on 2007-08-21 12:23 EDT
The October issue (on sale August 21) of Monthly Comic Dengeki Daioh has officially announced that a second season of the Gunslinger Girl anime series will be produced. The Japanese magazine runs Yu Aida‘s original manga about cybernetically enhanced girl assassins that inspired the anime. The production company Marvelous Entertainment had revealed that a sequel was in the works in its 2006-2007 financial report on May 30, but the company then edited the report to remove the Gunslinger Girl reference in early June.

Update (again from ANN):
The second season is now also confirmed by the official website of Gunslinger Girl. It will feature the Pinocchio arc from the manga.
