A secretive government agency called the Social Welfare Public Service Institution puts on the charitable face of helping out the public but it has a hidden agenda. A shadowy killing arm of the government, SWPSI gathers together little orphan Angelicas, wipes their slates clean, and turns them into terminators. Lethal in their new mechanical bodies and trained with precision assassination techniques, the diminutive slayers kill without remorse as their humanity has been taken from them...

Gunslinger Girl Volume 1 follows the 3-D action and adventures of a young girl named Henrietta who kills at the behest of the agency that has taken her in. The first production includes a bonus DVD with episodes 1-5 of the animation and a very large-sized 32-page artbook which contains some beautiful artwork inside.
