Misaka Mikoto was started to get a little ticked off.

Why?

Kuroko had been avoiding her. She had no idea why, but she was avoiding Misaka.

It had started a few weeks ago and Misaka had awoken on a lovely Tuesday morning, expecting the young teleporter to be asleep in her own bed (or next her) or the very least hear the sounds of Kuroko in the shower.

But there was none of that at all. The teleporter, along with her school bag, school supplies, school uniform and shoes were absent. Her bed was made neatly and it looked like it hadn't been used by anyone in years.

Ok, strange, Misaka had thought. But nice.

And it was nice because the pervy teleporter wasn't around to grope her or try anything lewd.

But when she didn't come home that night, Misaka began to worry.

What if she's hurt? She might need help!

But Misaka brushed these worried thoughts aside for something more logical.

She's probably doing Judgement work and if not maybe she's just having an outing and she's late.

And she believed those thoughts.

Until the Kuroko absent evenings and mornings happened more and more frequently, until she never saw her in the mornings and evenings at all for days in a row.

She knew she wasn't missing because she saw Kuroko in class and training outside, and she had also seen her with Uiharu a lot.

She had wanted to approach Kuroko and ask where she was at a time before 6 in the morning and after 9 at night. But she couldn't bring herself to say it, or anything for that matter. When she had tried walking up to her and Uiharu, she felt her heart leap into her throat, and she freaked and ran away.

So tonight, Misaka was going to stay up all bloody night and when she came in, (if Kuroko came in, that is)

She was going to give her a piece of her mind.

~Pretend this is a super cool line break~

"I am Kuroko Shirai, a member of Judgement. You under arrest for theft, assault and descrution of property. Hand yourselves over or face the consequences!" Kuroko said firmly and loudly.

She had already evacuated the area before anyone else could get hurt and she had informed Anti Skill already. Now she just had to catch these goons and she could go.

She had been at a disadvantage lately as she had not been using the earpiece to have Uiharu help her out. No, she had only been using it to contact Konori and Anti Skill directly. So without Uiharu's help, it had been hard getting a sense of direction. But she was doing just fine.

In fact she couldn't ask Uiharu to help even if she wanted too. As far as she and Saten knew, Kuroko was taking a break from Judgement to focus on other things. So instaead she made Konori swear on her life that she wouldn't tell anyone that Kuroko was working and that Konori herself, from time to time, was Kuroko's eyes.

There was a long silence between Kuroko and the thugs and Kuroko actually thought they were contemplating handing themselves over to her.

But this is Academy City, where wishful thinking was not your greatest friend.

The brunette man in the front, who was insanely tall started to snort, while the blonde and black haired men behind him (again, insanely tall) began to laugh.

Kuroko felt her face fall the slightest bit.

These thugs must really love doing things the hard way.

This was going to be a very dangerous battle, because this battle was going to be a rooftop battle.

The three amigos had the advantage by being on the higher ground, a building just a little taller than her's.

The moon was just starting to pass over the three criminals and the one Judgement officer when the blonde man began talking.

"Little girl, you have no idea who you're messing with." He smirked and just like that him and the black haired man disappeared.

W-wait! Optical control? Like Komaki?!

Just as that thought passed through Kuroko's mind she heard a few grunts and something leap and land on her rooftop.

Yep, that proves my theory, Optical control, I can hear them to pinpoint their location but I can't see them. Man I hate invisibility.

The two men revealed themselves to be both behind and in front of Kuroko, each of them smirking deviously.

Kuroko whipped her head around, anticipating that the men were going to jump her, but they just stayed there and waited.

But what were they waiting for?

But then she remembered that there was one man left.

She turned her head to try find him, the black haired man in front of her barely giving her a view of him.

When her eyes locked with the brunette's, he smiled an unsettling smile and suddenly her world started to go dark. She wasn't passing out because she could hear things clearly, she was thinking straight and her vision wasn't blurry. It just seemed like someone had turned the lights out. But you can't turn the moon off like a night light, so how-

Trick art, it has to be. They're all espers?!

Right after her theory was proven right, it was then that Kuroko started to feel the pain.

Someone had kicked her in the chest, and hard. Then she felt things digging into her legs and face. Sharp things.

Then she was being punched in the gut.

All she could hear were the laughs of the three men who were all getting turns of punching and kicking the tiny girl.

And then like someone had flipped a switch everything in Kuroko's vision went bright white, making Kuroko yelp and whimper in pain, squeezing her eyes shut.

He's manipulating the moonlight to blind me!

And as if the world thought that enough pain had been thrown at the petite girl, she heard the demanding, and somewhat comforting voices of Anti Skill officers.

Kuroko was now on her feet, but hesitant to open her eyes. She could hear some officers demanding the three men to turn around to be handcuffed and from what Kuroko could hear, they're demands deemed successful as she could hear the men start to be escorted of the rooftop.

Some came up behind Kuroko and started guiding her somewhere.

"You can open you're eyes miss Shirai, everything is alright now." She heard a young man say.

Kuroko did as she was told and was met with chocolate brown eyes.

Okay thank god, I'm not blind.

"I'm going to take you to the med team now, okay? You took quite a beating." The man said, as he guided Kuroko down the conveniently placed ladder down the side of the building.

"I-i couldn't teleport." Kuroko stuttered defeatedly.

"Hey it's okay, sometimes when espers are stressed it can cause them to loose control over their abilities, it happens with my younger brother." The officer said.

Stressed? Anxious absolutely. But stressed? What was there to be stressed about? She was excelling in her school studies, training was improving and her abilities were getting more and more stronger as the days went by. Yes, she was intimidated by the three men, but she couldn't rack her mind for a reason why she might've been stressed. Maybe her constant anxiety was the stress.

When the pair reached the ground she was whisked away by the med team, the nurses flooding her with concern. Up until that point she hadn't even looked at the damage, all she knew was that everything hurt.

She could feel blood dripping from her forehead down her face and her arms and legs were scraped and since she had been pinned to the ground by two men with the third stomping on her chest, reeling in some oxygen was still a challenge. The med team were cleaning her cuts and scraps and the massive gashes on her stomach, back and head, the head wounds pouring blood down her neck and the chest and back wounds starting to blossom blood through her uniform.

So to say she was feeling light-headed could be deemed understatement of the year.

When she left the med team she had a patch on top of her forehead and on her cheek and bandages were carefully wrapped around her torso wounds. Thankfully only a few spots of blood had started to seep through so if she got up early she could wash it in the morning, she couldn't wash it this late as the dorm lady wouldn't hesitate to punish her.

After a short conference with a few Anti Skill officers and quick goodbye to the officer who helped her down the ladder, Kuroko was on her way.

It was currently 10:45pm and Kuroko was tired. She thought of teleporting her way to the dorms so she could hop into bed quicker but she also didn't want to risk getting to her dorm with the dorm matron and Misaka angrily waiting for her. So, despite her tiredness, Kuroko's legs carried her the long way to get to the dormitories.

I'll just take ages getting home so even if they are up now, they'll get tired and go to bed.

She was coming up to the 1 hour mark in her walk to home with half an hour left to go when her vision started going blurry and when she looked down and saw she had what looked to be eight fingers and two thumbs she knew she was on the verge of passing out. A nauseating feeling was starting to curdle in her stomach and she could feel bile and flem leaping in her throat.

She threw up on the footpath for good two minutes and then kept walking.

She was feeling dangerously dizzy, her eyes started hurting and her face felt icily cold but her body was betraying her face's heat as her body felt like it was going to explode with heat.

Kuroko fell to the ground and tried to collect her breath but she wasn't reeling any air in. There was an incredibly huge invisible weight crushing her chest, threatening to break her into pieces.

A panic attack.

Panic attacks had been coming quite close friends with Kuroko lately but every single time she still gets scared that she'll never breath again.

Nosies were either too quite are too loud and light was either too bright or too dark, and sometimes smells were just too strong or she could smell anything at all. Sensory overloads, Kuroko thought they were called.

The attack was quicker than usual, but the quicker the better as it was now 12:17am and although she wanted to take long so the dorm matron would forgot about her (if she even remembered her for starters) she was missing her bed and she still needed sleep.

And she needed to get ready for tomorrow.

Kuroko had been doing...special things lately and those things were causing her schedule to go haywire.

She would get up insanely early, earlier than Sissy, get her bag and herself ready for the day and leave. She would do special training at the ungodly hour of 4:00am and then get into her uniform, freshen up and go about her school day. Than after school she would go on patrol and preform her Judgment duties, cleaning up garbage, helping with traffic work. Then she would do her...special things, do more Judgement work and then go home very, very late.

But she had also been making no time for her roommate, her best friend, Misaka Mikoto, Sissy, or more commonly known as Tokiwadai's 3rd ranked Level 5 Esper, Railgun.

To Academy City, she was a hero, a goddess. But to Kuroko she was humble Misaka, a great friend and her Sissy. And she loved her. And she understood that she came off as pervy, but she then realised that she didn't deserve Misaka, and she didn't want to force anything onto her.

So she hadn't tried anything and she didn't plan to try anything ever again, be it with Misaka or another person entirely. Plus the perv persona was a facade, her close friends knew that, including Sissy. On the inside, Kuroko was a scared tiny girl who just cared too much about others wellbeing.

Plus, she knew that Misaka had a small thing for Touma anyway, so what was the point, if she loved her but Misaka didn't love her back?

Of course there was another reason she was keeping her distance from Sissy, but that wound was to fresh to even think about.

Kuroko was starting to teleport herself but something was wrong.

She wasn't teleporting properly. She couldn't teleport that far away, maybe a few feet each teleport, and each teleport was draining her.

The teleporter took another 15 minutes to make it to the dorm on time. Before entering the building she stroked down her hair and brushed off her clothes, brushing any grime and dirt off of her clothes and body, using a nearby window as a mirror. Once she was satisfied she tried picturing the hall outside her room and when she was happy with her calculations, she focused her mind to take her there.

Kuroko opened her eyes and to her pleasure she found herself in the exact place she imagined.

Kuroko slowly shuffled to the door and turned the handle.

~Again, an awesome line break~

Misaka had been pacing. It was 12:30 and still no Kuroko. She considered calling authorities when she suddenly heard a thump and familiar whimper of pain.

Got'cha

The doorknob turned slightly and Misaka quickly and soundlessly ran to lay on her bed.

When the door opened Misaka saw the little teleporter she had been missing.

Kuroko sighed loudly and kept whimpering.

She's not hurt is she?! Misaka panicked. But she didn't show any serious signs of pain so she let the anger take over.

"Care to explain where you were?"

Kuroko turned around and yelped loudly. It was a cute noise, kinda like a kitten.

That really doesn't matter at the moment.

"S-Sissy! I-uh, while you were sleeping I quickly went to...um..." Kuroko stuttered.

Misaka had already caught onto her lie, she hadn't fallen asleep yet. But she wanted to see what lame excuse Kuroko could whisk up to get her out of this mess.

"I went to the...bathroom...?" It came as more of a question than it did a statement.

"We have our own bathroom. Why would you need to go to a different bathroom?" Misaka asked, bolts of electricity dancing around her body, threateningly.

"B-because, I...am PMS-ing! Haha, yeah and I, uh, needed...stuff." Kuroko mewled. Her cheeks were blushing a strong crimson and it looked like she was going to either burst out laughing or start bawling her eyes out.

She couldn't even believe her own lie even if she wanted too.

What happened next was an accident and Misaka didn't even realise what she did until she heard Kuroko whimpering in pain and squirming on the floor.

She had zapped her. Which she didn't mean to do.

Usually when Misaka zapped Kuroko it was because she had pushed her limits and Misaka always made sure she didn't hurt Kuroko. But this time was different. Kuroko hadn't tried anything (she hadn't tried anything for weeks) and she certainly hadn't done anything that would make Misaka want to zap her...besides lying to her face.

But that was the thing, she hadn't meant to zap her. It just happened, she didn't have control over the zap.

What the?

Kuroko has hugging her torso and whimpering. Usually Kuroko bounced back from zaps and she sometimes even dodged them. But she hadn't been knocked down so hardly by them.

"Kuroko! I-I didn't mean to zap you! I'm sorry! I'm so sorry!" Misaka rambled, the angry facade completely wiped and replaced with her concern and worry.

Misaka bent down so that she was kneeling in front of Kuroko. She wasn't crying, thank goodness. If Kuroko was crying she might have started to cry to.

Misaka put a hand on Kuroko's shoulder, trying to soothe her.

"I'm sorry, I didn't mean to hurt you." Misaka said quietly, trying to catch Kuroko's caramel, strawberry eyes.

"Yo-you didn't hurt me." Kuroko said quietly, as she looked up with huge shining and glossy eyes, quickly locking them with Misaka's.

"Who did?" Misaka asked sternly.

Kuroko didn't awnser, she only stood and walked away, leaving Misaka by herself on the floor, her hand reaching to try catch Kuroko's wrist as she walked for the bathroom.

She missed.

Kuroko was only proving her little lie more wrong as she entered the bathroom with clothes in hand.

How did she grab those?

But that wasn't the point. The fact that when Misaka implied that Kuroko may had been hurt by someone, Kuroko immediately shut up, as if she was talking anyway.

Kuroko came out in her pyjamas, consisting of a beige shirt with a sleeping grey kitten with the words 'Soff Kitty, Warm Kitty' on the shirt and shorts that were a light beige colour and they had little grey cats on them.

It was another thing that was weird. Kuroko hadn't been wearing her usual skimpy lingerie to bed either, one thing that Misaka kinda missed. But not in weird way! It was just weird that Kuroko was barely showing any skin in intimate places, as Misaka was so used to Kuroko show at least a sliver ove stomach or a little bit of skin from down south.

Kuroko slipped into bed and turned away from Misaka, and Misaka couldn't help but feel a bit hurt.

All these little things, the absence, no showing of skin, no pervy actions and a quiet Kuroko was unnerving to Misaka. She had become distant, to Misaka's dismay, and although she didn't miss the pervy-ness (well maybe a minuscule part of her did) but she missed the Kuroko that was her best friend.

She missed her so much that it really, really hurt.

But she was right there, across the room from her.

So why did it feel like she was gone?

~Line break dance, line break dance, whatever could mean?~

She heard Sissy slip into her bed from across the room and she heard her turn of her lamp.

They lay there silently.

She hadn't expected that zap to hurt. Sissy's zap rarely hurt her as she was not a threat whenever she was being zapped (besides going to far with her lewdness...that's considered a threat right?) but this time it was excruciatingly painful, Kuroko could still feel the burning sting course throughout her body.

But it wasn't the initial zap that hurt. No, it was where it had hit.

Of course whenever Misak electrocuted her, it wasn't painless, it without a doubt stung everytime. But Misaka had zapped her abdomen, attacking her injuries and dear god was it painful for the poor tiny teleporter.

"Kuroko, I really didn't mean to zap you, I couldn't control myself." Misaka whispered quietly.

"It's fine Sissy, I'm not angry." Kuroko said rolling over to face Misaka, a small, comforting smile on her face.

"But why don't you tell me truth? I don't understand why you can't tell me where you were." Misaka said, a sad frown on her face.

Kuroko knew she shouldn't tell Sissy and she wasn't planning to ever tell Sissy what she was doing, but she knew that if she told her what happened tonight it would lead to her spilling about her injuries and she didn't want Sissy freaking out about a few bruises.

So she lied, but though about a bit more this time.

Make her believe it.

Kuroko sighed miserably. "Ugh...do you remember a few weeks ago when I was late to join you guys at the diner? You know before I started leaving early in the mornings and coming late home in the nights?" Kuroko said as she had already suspected Misaka knew she had known if Kuroko's absence in morning let alone the evening.

Misaka nodded quickly, eager to hear Kuroko's explanation.

"Well I was held up by the director of the school and Konori...and the director had been informed by Judgement that my Judgement duties had been a liability to me, as I kept getting hurt doing patrol. So Konori had told the director to make sure that I wouldn't do any work outside of school. I, of course got angry so as punishment for arguing with Konori and the director, I have to help the janitor clean in the early mornings and late evenings."

It was quiet for a moment and Kuroko had hoped that Misaka had bought it.

"Oh. Then why did you cover that up by saying you were on your...y-your period..?" Misaka said, confused and slightly embarrassed that they were on the topic of the young teleporters menstrual cycle.

Crap

"I was just embarrassed to tell you that I was cleaning up around the school." Kuroko whispered.

"I find periods a bit more embarrassing than cleaning up Kuroko." Misaka giggled quietly.

Kuroko giggled along with her.

She bought it.

Kuroko thought that was the end of it, Sissy would get of her tail and she wouldn't get involved, let alone anybody else.

But boy, was she wrong.

AN: A WRITING RECORD!! 4K??

Anyway, priso- I mean, school has been a nightmare. I've been swamped with work (oof) so writing has been I consistent.

Now I've only just entered the Railgun/Index fandom, so forgive me if anything is wrong. But I love this ship so much that it hurts, so I just had to write a story. ( Go watch Index first then Railgun, they're both on Netflix ;) )

!THIS ISN'T A ONESHOT!

I plan on making this a series! (I know handling two series's at once, I'm just adding more work to this towering pile of schoolwork)

Please stay tuned!
