Gunslinger Girl
The Social Welfare Agency in Italy is not what it seems. Yes, it rescues young girls who have been brutalized, but it then brainwashes them and turns them into ruthless killers for an elite and secret counter-terrorism unit for the Italian government.
Enter a young girl named Henrietta. After witnessing the savage murder of her family and barely surviving, the Agency takes her in and repairs her injuries using the latest in cybernetic technology. All traces of Henrietta's past are wiped from her mind, as she becomes one of the Agency's most lethal assassins.
