[Who was the one who got hit by the long range snow ball, tossed by Mikoto?]
This scene follows up Electric Princes on Saturday during the Pool Scene competition;when Mikoto threw her snowballball towards the roof against certain person. Target of #3, was a person with a (long distance camera lens?) hiding on the roof, watching said stage from a safe distance.
But that safe distance did not apply to the Railgun and her experience with sharpshooting, which even a professional sniper would not be ashamed of. Who will not try to shooting at empty cans, near the river bed, under a bridge? Especially, when you don't need any special equipment to do it.
A detailed study could be written about how she managed to send that snowball to such a distance. But for an amateur, a trifle like the fact that she secretly mixed in iron sand during the creation of this projectile, is enough. She strengthened the surface and gave the whole thing an electric charge. This apple peel, one molecule thick, protected the snow core during flight from the effects of physics. So the target took a good beating from what should have been something as defenseless as a snowball. However, at Level 5, the reality of common sense goes to the trash bin first.
So the mentioned target (girl) went to the ground with the legendary "Kia!" shriek. So she actually stretched herself backwards on the mentioned roof. Covered by drops of snow spread everywhere, she was staring at the sky.
But the neutralized girl wasn't Kuroko Shirai or any of her accomplices, who were supposed to use a camera with a long lens to have an unobstructed view of the contestants. Actually, what was now lying next to this girl was not the aforementioned camera with a large lens, but a long military sniper rifle with a large lens. And the girl in question was one of the sisters.
.
With a displeased expression, she removed her Electron (NV) Googles, which had been directly hit and still had traces of snow on them, from her eyes. Even her clothes had traces of snow in their upper part. "Really? A snowball? Misaka should be celebrating that she survived the encounter with Level-5, but she's also unhappy about the reference to bad memories. So she instead sighs at her older sister's cruelty and the disproportionate lesson." As she said, she sighed, closing her eyes for a moment to rest.
(Kuroko, who was on guard-duty again, noticed that her Sissy actually had hit someone with that sharpshooting, (perhaps a suspect). So this boss of event went to investigate.)
Back on roof, there was the sound of a teleport and a certain red-haired girl bent over the resting brown haired girl, actually self inviting herself to Misaka's field of view. "Ara, ara; What do we have here? That's an interesting sight that occurred to me." Her gaze also fell on that rifle. "This is a school and not an army training center. You shall be glad that Sissy has not overreacted."
.
You can probably imagine the shocked look on Imoto's face when she saw the person above her. "Shirai, Kuroko…" She said (emo-horrified?), then her body twitched slightly and her hand moved toward her weapon.
The girl from judgment was strict. "Hold on, I didn't come to fight! Why do you think everything has to be about fighting anyway?" She stop herself for a second with her Sissy face on her mind, and shake her head with never mind expression. "That is,-- unless you intended to use the item for some nefarious purpose. Then I'd rather you just give up without a fight."
.
Misaka's body twitched again and remained completely motionless for a second or two as she had to go through the suggestion. As the snow melted, her clothes soaked through in places. But then she crossed her arms over her chest in an (irritating?), (offended?) gesture. No, since she pulled her outstretched legs and thighs close together in a defensive gesture, those arms also had to protect the appendage on her chest from a possible deviant.
Of course, the redhead's eyes immediately devoured the pasture for her eyes with the (soaked?) brunette. "Why is your first reaction like that? Don't try to wriggle out of this by d-- distracting me!" The redhead took offense and turned away her blushing face. "Well, it doesn't matter, you'd better tell me how many little sisters Sissy has?" She clearly glanced toward the podium in pool where Mikoto, and other Misakas participate in event.
.
Misaka gave a rather incomprehensible explanation at the end of which she simply said the number: 9975 [Explanation: 20k base, then; Last-Order, Worst, Febry, Jannie, Dolly, (Will of M.I.S.A.K.A) = 20006 – 10031 (experiments done) = 9975 (not counting Mikoto, Misuzu, the disconnected unit/failure)]
The confused redhead tilted her head to the side, absolutely not understanding what the code meant. "Eh? Ah... I see…" She gave that weapon another glance before returning its sight on Misaka. "Well, I should confiscate the toy of yours, but there would be so much paperwork with that dam thing, that we'll end this nonsense today with a warning. (This is a school, not a military base! That kind of thing doesn't belong here. Please return the thing where it belongs and that's stored under lock and key.)" She sighed. "Do you understand how much panic it will create if you shot that or people will miss understand, your intention. Don't cry, if you got schooled for damaging Tokiwadai reputation if someone saw you, reported you, and you will be put on questioning." She lightly look around if someone not spying on them, while playing with one of her pig tails. "I still have responsibilities and I have to go back to work. Use this time to think of your actions." With those words, she teleported away, leaving Imoto alone.
.
She lay there for a while before she relaxed to point much that she just spread her limbs over the roof. "Observation failed, due cruelty of Onee-sama and goosebumps from Shirai Kuroko; Misaka states, as she raises a protest to a certain Misaka, who is all too enthusiastic in describing the rich, textured flavor of her dish to the network. Misaka sighs in effort, raising her food order request." She put her glasses back on, but suddenly had a surprised expression. "Oh-- My EM-NV glasses seem to have stopped working. Analysis showing a short-circuit malfunction; Misaka needs a replacement."
Making a deep sigh she put them away from her eyes to stare at sky for few seconds, until she get up and start packing her stuff.
.
[Later, this Misaka got into the hands of the cosplay club. In the end, she got black sunglasses and fingerless weightlifting gloves, plus a guitar case for the rifle. So she obtained a cover of rebellious guitar girl.]
[Note:] Also now, I shall not count (Will of M.I.S.A.K.A) into the math equation because, she refer to sisters as her terminals.
