Author's Note

Hello, welcome to my fanfic.

This is my first foray into writing fanfiction but I assure you I am a veteran reader.

This story is an A.U. which takes place in a universe where both Saten and Misaka, for different reasons, joined Judgment. The primary ships are femslash with a few exceptions (Who to ship Touma with is pretty up in the air) but I hope that doesn't dissuade you if you do ship something different, the romance between pairings will be slower anyway, as this isn't meant to be a romance (Sometimes I have difficulty not writing romantic tension). I have not started watching the primary anime (A Certain Magical Index) or finished the spin-off (The one I'm writing about) but I do make sure to do research before I write. If their are questions or you do see something you think is entirely wrong, please leave a review. If you are interested in the progress of this story, maybe follow or favorite the fic.

I hope to have a chapter every 1 or 2 weeks.

Authors notes will not be in every chapter, but if they are, they will be at the end of a chapter from now on.

Anyway, hope you enjoy.

Human cities are modeled like a human body. Networks of roadways and utility services act as vessels and nerves while governing bodies (despite what the citizen of said town might say) act as the brain. The best parallel is between law enforcement systems and immune systems. White blood cells and other immune cells act as protectors of the body. A good and healthy immune system keeps the body healthy, while a bad immune system can becomes worse than the illness they are made to protect against.

Saten Ruiko believed Academy City had a pretty good immune system. Considering it had someone akin to mythical cure-all within its ranks.

'She works fast.' Ruiko thought as she watched her senpai shock some thugs senseless. Of course, the famed "Judgement from Heaven" Misaka Mikoto was certainly not fond of entertaining any banter and preferred abating both her frustration and the injustices she saw as fast as possible. Ruiko poked one of the crispy criminals with her foot, receiving a pained groan in return.

"Anti-Skill should be over shortly, Misaka-sama." A kind voice over their headsets said. Uiharu Kazari was their goalkeeper, the person providing all intel between their squad.

"Copy that, Uiharu. Thank you."

A third voice, and person, appeared, spooking a stirred thug back to unconsciousness, "Onee-sama, you are too eager to do damage, as usual." The new voice was Shirai Kuroko, which, according to an amusing urban legend, was 'ruled body and soul by the greatest electromaster'. A statement she would probably agree with wholeheartedly.

"Personally, I think she might have held back. One of them woke up for a second there." Ruiko interjected, the corner of her mouth pushing up slightly. She knelt down with a pair of handcuffs, readying the troublemakers for pick-up.

"Did you catch the runner Kuroko?" Mikoto responded, starting to cuff the thugs closer to her.

"Yes, Onee-sama!", was the enthusiastic response.

"Good, Uiharu, can I get an ETA on Anti-Skill?"

"A van should pull up in forty-five seconds."

"What was our response time?"

A second passed as Kazari did some inspection. "The issue was resolved in 2 minutes and 57 seconds, lower than the national average by 2 minutes."

Mikoto nodded and smiled slightly.

"Not bad, we can see if we can get that lower later."

Bzzt! Thunk! Curchunck!

It amused Ruiko how casually her Sergeant broke some rules. Kuroko had of course facepalmed and attempted to make herself as not visible as possible as our honorable sergeant disregarded her position and zapped an innocent vending machine for a free drink.

"Onee-sama, why must you still wear those childish shorts underneath your school uniform."

Our esteemed Sergeant flushed red and coughed some of her soda out. "Perverted kouhai go to HR meetings for accosting their senpai. Long, boring meetings." She said as she simultaneously did something Ruiko thought HR may disagree with, in shocking her younger colleague, after doing something HR would certainly disagree with, stealing a soda from a bugged-out vending machine. A large shadow then passed over Ruiko.

"System scans today," Ruiko spoke up, drawing the attention of her friends. They looked to her, then followed her eyes to a blimp hanging in the sky. "I better be off."

"Yeah, see ya, Ruiko." Mikoto sounded distracted as she continued staring at the blimp.

"Let's meet after school at the usual place. See ya Ruiko-chan." She then grabbed Mikoto's hand and they were gone. Teleported away in a blink.

Ruiko felt some envy towards the convenience of such a power but quickly shook it off and headed in the opposite direction towards her own school.

As she started off, she opened up her comm link to Kazari.

"Morning, Uiharu-chan."

"Ah-h, Saten-san, is something wrong? Did you run into trouble on your way to school?" A worried tone, being the only detectable flavor to the voice. A rather overpowering flavor at that.

"No, no just figured we could talk and walk."

"We shouldn't use official channels for talking casually. If an emergency arises it must remain free." A chastising tone with undertones of exasperation and fondness.

A smile grew on Ruiko's face and breeze blew through her chest. A wonderful flavor for a voice.

"Fine, fine, I'll meet you at school then, in about 5 minutes." She hung up before Kazari could get another word in and put her comm in her bag, along with her Judgment sachet.

As she continued her walk, her thoughts went back to thoughts of the System Scan. The results were almost certain, making the test a waste of time. It would certainly say that she was a level 0, bottom of the totem pole. But even so, she held hope that maybe this time the test would pick something up missed by the dozens of tests previous. Of course, the scan also tested other aspects of your fitness, such as endurance, strength, and brain health. In this regard, she was at least happy with her progress. She was at least as fit as Kuroko, though not as skilled a fighter, even disregarding Kuroko's ability. Her grades may be average but Ruiko knew her talents were suited to less academic pursuits and so she didn't put much mind towards them. That was more Kazari's area anyway. And, of course, Mikoto's…

Her thoughts were interrupted by the sight of Kazari coming into sight and looking at her phone. A mischievous smile made its way onto Ruiko's face. Theories and ideas ran through her head as she approached her friend quietly from behind. She gently crouched and grabbed the bottom of the lovely skirt in front of her. Then with all her power, threw its bottom skyward, showing off Kazari's backside to all who could see.

"Ah, I suddenly feel nostalgic for the summer sun at a crowded beach, but these certainly create a similar effect, huh, Uiharu-chan."

The effect of her words was immediate. The shorter girl jumped away, did a 180 degree turn, gained a vibrant red hue, and began smacking Ruiko's front.

"Saten-san, why must you do this to me?" Her voice rose slightly at the end. Very cute.

"So formal with your friend and colleague Uiharu-chan," A bell went off. Too soon. "Lets walk in together." She turned Kazari towards the door and put her arms around the slightly shorter girls neck.

"Ruiko-san, you troublemaker." Her face still red and her petulant tone making her appear cuter. Ruiko laughed as they walked towards their scan. Renewed vigor within her she decide it had been a good morning despite the hold ups. Her friends were great.
