Brainwashed girls who do not have any relatives or any place to go are being trained as professional assassins and given mechanical bodies by a so called non-profit welfare organization. They have lost their consciences and do not hesitate to kill at all. They spend their lives smoke stained, covered in gunpowder and blood.
It's a sad story about suffering girls who have lost their past but who still cling to life. After they are brainwashed, they can kill with an innocent face and without any hesitation. They don't think about their deeds nor feel any pity. However, behind their cute disguises, they are destroying themselves and refusing to grow up.
