Synopsis
The episode starts during night time; a slender-looking white-haired boy is seen walking out of a convenience store carrying his groceries. Meanwhile, a girl who looks suspiciously like Misaka Mikoto, the Railgun is seen on top of a rooftop, wearing military goggles that have a bluish-green color. The girl is holding a mounted, positioned to fire down the streets below. The winds blow her hair, and she speaks in an eerie monotone voice, she adjusts the scope of the gun to accommodate the change in the weather conditions, the target is the white-haired boy. The wind blows again, and once again she adjusts the scope of her rifle, she readies to fire and confirms the target's name, Accelerator. She fires the gun several times, seemingly accurate. The bullet should hit Accelerator, however, in a flash the bullet returns to its bearer, destroying the gun and hitting the girl. She is severely injured, frantically she staggers to run away, apparently afraid of something. She runs into the alleys, and sees the object of her terror. There, awaiting her with a smile, the white-haired boy that should've been killed stands; Accelerator.

Trivia

 * When Maika mentioned that she and Motoharu were making noise during the night, it may be a, considering how Motoharu is sis-con (someone who has sister complex or an attraction to sisters) and that Maika reads manga where siblings develop love for one anoter, which will be referred to later.

Cultural References

 * The flags Aisa is referring to are event flags in many and, where one can access the story routes as well as other flags of the subject after triggering certain conditions.

 * is referenced as well by Misaka 10032, as a name for her cat. Here, Touma states that naming a cat Schrödinger is a taboo, which is a reference to his famous which included a cat inside a sealed box, that maybe alive and dead at the same time until someone confirms that the cat is either alive or dead when the box is opened. This thought experiment will be used in a later episode, to explain the Power Curriculum Program of Academy City.

Differences in Adaptation

Animation Trivia

 * The Misaka clone seen in the opening fires several bullets at Accelerator, however, only 1 seemed to have redirected back to the clone. Also, note there seems to have been little to no recoil at all during the firing of the rifle.
 * The Misaka Clone calculates her bullet trajectory according to the wind. Since Accelerator's redirection would send the bullet back following the bullet's original trajectory, the bullet should not have hit back directly at the Misaka Clone for there is also wind on the second trip.
 * Around the 10min 39sec time frame, Misaka puts the night vision goggles on but then has them in her hand in the next scene, and the back on her head in the next.
 * During the scene where Touma argues with Index and Aisa, you can see that Sphynx tail is wiggling back-and-forth, however, if one pays attention, you can also see Misaka 10032's eyes moving back-and-forth as well watching Sphynx's tail wiggling.
 * Just before Misaka shoots to Accelerator two people that resemble to Akito Takagi and Moritaka Mashiro (Bakuman protagonist) walks near him.
