AAA can be programmed to be autonomous

The black, bench-sized mass resembling a streetcar or police van approached the shorthaired girl while she stood entirely motionlessly. It must have received a command from
its true master because the A.A.A. changed shape with several mechanical noises. It
regained its original form that remade the girl’s silhouette into a metal-winged demon.
With that, the weaponization was complete.
That girl was now a fighter who would crush that other boy.
But.
A moment later, one of the weapon arms gave a roar and opened fire on the tuxedo boy
standing nearby.
“…!?”
Shokuhou was even more surprised than the target of the gunfire.
The cat could not “scream”, so it instead uttered a twisted meow.
Misaka Mikoto was still unconscious. She had to be.
Nevertheless, the blue veil on her head fluttered like a curtain while her arms and legs
were forcibly moved by an external force, as if they were attached to invisible strings. The
blue lingerie dress clearly revealed her bodylines, but she made no attempt to hide the
milky-white skin seen through the lace and she did not even blush.
And.
A few tufts of black hair fluttered through the air.
Black.
The attack had been too quick to dodge if you reacted only after the oddity had begun.
Did that mean the boy had been considering this a possibility in some corner of his mind?
He was powerless, weak, and unable to survive even a single hit. But that was why he had
to be cautious.
There was a slight flash of shocking pink.
It came from the corner of his mouth.
“Shoku…hou!!”
“No! It wasn’t me!!”
Even as she shouted, her clever mind worked out the answer with a swiftness that
disgusted her.
(The A.A.A. is a purely mechanical product, so Mental Out doesn’t work on it. So did
Misaka-san change some settings in its programming in advance so it would attack him
once it connected to her!?)
That girl would be of no use like this.
Shokuhou could only control Misaka Mikoto who was dangling from the machine like a
limp doll. If the exterior A.A.A. had taken control of the human-machine unit, then any
stop command Shokuhou sent would be meaningless. That would only start a hopeless
arm wrestling match in which Mikoto tried to use her muscles to stop the mechanical
arms from moving.
