More engaging that I'd initially suspected. It's a weird mix of controlling AI, fear and opera - Space Opera not usually being as literally interpreted as this - especially the 2nd installment which is very heavily Phantom based.

In an isolated system Toccata - AIs control much of civilization but are strictly limited in how much personality they are allowed to gain. A scientist attempts to increase this thinking to bind they're loyalty to himself. But as may always be predicted it all goes wrong, and he earns the undying enmity of one particular AI. 'She' in turn raises a small army of jilted or abandoned girls as assassins in all forms to track him down for 'her' ultimate revenve. This is the girls' story. ( )
