The girls of the Social Welfare Agency are no ordinary children. They are the grisly remains of human wreckage pieced back together with cybernetic implants and trained to kill by the government. Once human, these shattered souls have become murderous machines with only vague recollections of what it meant to be real - and a brutal compulsion to be the last killer standing.

Contains all of Gunslinger Girl, Gunslinger Girl: Il Teatrino and the Gunslinger Girl: Il Teatrino OVA!
