"Will Kamijou-chan and Accelerator-chan please go to the nurse's office," Konoe-sensei told the two boys at the beginning of class. It was the morning of Accelerator and Last Order's third day of school, and had actually started like a normal day.

Both boys stood and began to make their way there; Last Order stood too, intending to follow them.

"No, no, Last Order-chan, you should stay here. They need to under go some tests because of Judgement, so it's best if you leave them too it."

The brown haired little girl looked to the white haired teen for confirmation. When he gave a stiff nod of the head, she deflated onto her desk, disappointed that she couldn't follow them.

The two boys made their way in silence; neither of them liked undergoing any of the usual tests, one because it brought back bad memories, the other just because he found them troublesome.

Once they entered the room, they were greeted by two young nurses who separated them behind a set of curtains. Neither woman worked at the school, and so must have come for the express purpose of performing the tests.

"Alright, shirt off," the nurse with Touma ordered, grabbing a stethoscope. Touma blushed as he stripped off his shirt in front of the pretty woman, (he could have sworn she was leering at him as he did so) and then found himself flinching as she placed the cold metal disk on his chest.

And so began a long and tedious series of tests that took up much of the day, as their pulse, heart, AIM and blood was tested, as well as a lot more.

Finally though, Touma was handed two containers and asked to go to the bathroom and fill them.

"Er, I get what one of them is for," Touma began, shaking the container in his left hand, "but what's this one for?"

The nurse gave him a brilliant smile that told him she was suppressing laughter for the sake of professionalism. "We need a sperm sample too."

"Wh-What?" Touma choked out.

"It's part of the tests. Just do it," she told him with a giggle at his glowing red face. "Unless you need some assistance?"

Mortified, the spiky haired teen had no choice but to comply. He gave a silent promise that he would never speak of this to anybody as long as he lived.

The school day had only one class left by the time they finished, and with both of them rather put upon, neither boy felt like attending. They ended up waiting outside in the courtyard, soaking up the sun, or at least what little of it was left this late in the year.

"We start tomorrow," Touma was the first to speak.

"So what of it?"

"Do you want to go and visit today, meet our sempai?"

"Sempai?" he sneered. "You do realize that apart from that big breasted glasses girl, it's just a couple of middle school brats?"

Touma shrugged. "You know as well as I do age isn't important. Misaka is a Level 5 and she's a middle school girl. Besides, Judgement doesn't usually go around catching dangerous criminals; that's the Anti Skill's job."

"Tch, they're probably just a couple of naïve and innocent little girls."

"Like Last Order?"

Accelerator was silent.

"So, you want to go or not?"

"Why the hell should I?"

"What else do you have to do?"

"Fine! Let's go meet them!" he eventually spat out.

They waited for classes to finish and Last Order to arrive in silence, only very occasionally broken by Accelerator grumbling and shifting, while Touma lay more still.

Eventually though, just before the bell rang to signal the end of lessons, Touma got up to make a call.

"Ah, um, this is Index," an unsure voice came from the spiky haired teen's phone after two rings.

"Index, -"

"Touma!"

"Yes, it's me," he sighed. "Listen, I'm going to be visiting the Judgement branch office today. Do you want to come along and meet me there?"

"Of course! I'll meet you there!" With that she hung up the phone.

Touma closed his eyes and counted to ten. At eight, his phone rang and he quickly told her the address and the fastest way there from his house.

"Who was that?"

"This girl a take care of," Touma answered simply.

Accelerator nodded, accepting that easily. If he could take care of someone, it stands to reason the hero would as well.

Eventually the excitable brat known as Last Order appeared, and they set off with as little hassle as possible.

She grabbed both boys' hands as they walked, more than happy to be between her two saviours. She took occasional swings on them by jumping up without warning and letting the two swing her.

She was a little old, or considering she was a clone, big would be a better description, and heavy, so every time she jumped, the weak Accelerator stumbled and broke out into a series of curses. Not once did he ever tell her to get off.

"Can Misaka call you Onii-sama? Misaka asks as Misaka grips her black haired saviour's hand tighter."

"Onii-sama?" Touma considered this for a moment, and then finally nodded. "If you want, but why?"

"Because if all goes according to plan you will be Misaka's older brother Misaka answers easily as Misaka ignores the pleas from her underlings."

"Huh?" Touma looked to his white haired companion for clarification, but he seemed to be as lost as Touma was.

Shrugging, they continued on their way.

Kuroko kicked her feet as she sat in front of her desk in the branch office. She was just finishing some paperwork as Saten-san and Uiharu walked through the door.

Using her Teleport, Kuroko was usually the first to arrive, even though Tokiwadai was the furthest school away.

"I'm not so sure Uiharu. I've heard he's a psychopath."

"That can't be true! I bet he's just misunderstood."

"Hmm, who is a psychopath?" Kuroko asked her newly arrived peers.

"Ah, Shirai-san" Uiharu greeted. "Tell Saten-san about Accelerator; she keeps saying he is dangerous."

"Hey, hey, I'm just telling you what I've heard. Do you know anything about him Shirai-san?" Saten asked as all three moved to the office couch. The paperwork could wait a little while.

"A little; he's the number 1 Level 5 with the ability to manipulate any vector that touches him. Mostly he keeps to himself, but anybody that interferes with him…. Well, it's not pretty. Apparently he was participating in an experiment, but that was shut down because of his defeat."

"Defeat?" Uiharu asked.

"Oh, oh, I remember hearing about this; he was defeated by a Level 0 in one on one combat, right?"

"Yes, that is correct. To make matters worse for him, a few weeks after his first ever loss, he was shot in the head; it caused massive brain damage that not even the advanced technology of Academy City could fix. From what I hear, the doctors managed to circumnavigate the problem, but he is much weaker than he was before. Of course, these are all just rumours and not established fact."

"Hoo, I see. So he isn't the strongest any more."

"I never said that. While it is true he is much weaker, he is still the so called Strongest. It is a testament to his power that even with this major setback, he retains his position. Even Onee-sama has admitted that she would be no match for him."

"Is he really that strong?"

"Yes. He may not be a psychopath like you said, but Accelerator is feared for his overwhelming power. How a Level 0 could beat him is beyond me."

"He punched me really hard."

Hearing that voice, all three girls shrieked in surprise, unintentionally jumping off the couch and into the air. They quickly span around and found themselves facing a boy with white hair and red eyes. His body was androgynous and he had one crutch under his arm to support his weight.

"Accelerator!"

"Yeah, that's me. Who the hell are you?" he asked, looking at the three in turn. "I thought there were only going to be two middle school brats."

"Who you calling a brat?" Kuroko snapped.

"You, ya brat!" he snapped, taking a menacing step forward.

"Ah, ah, calm down everyone," Saten intervened nervously.

"Hai, hai! No need to fight," Uiharu backed her up.

Both girls were jittery at the idea of a fight.

Kuroko sighed. "Yes, you are right. It's nice to meet you Accelerator-san. I am Shirai Kuroko, and these are two are Uiharu Kazari and Saten Ruiko," she introduced them, a short girl with short dark hair with a flower headband first, and a slightly taller girl with long black hair second. "Saten-san is not a Judgement member however; she is a frequent visitor and classmate of Uiharu."

"Fair enough."

"If I may enquire, why are you here? You and Kamijou-san do not start until tomorrow."

"That guy wanted to visit today, meet our co-workers; I decided to join him."

"I understand. Where is Kamijou-san then?"

Accelerator smirked. "Getting chased down by that third-rate electromaster."

"Who?"

"The Railgun."

"You mean Misaka-san is chasing Kamijou-san around? But why?"

"Hell if I know."

"Onee-sama, why are you chasing down that ruffian when you have me?" Kuroko yelled, teleporting out of the room, leaving the white haired boy seemingly alone with the two nervous middle school girls.

Slowly though, a small girl peaked around from behind the door and into the room. The two girls immediately focused on her.

It was Last Order, and to the two girls who knew nothing of the Level 6 Shift experiment, it looked like Mikoto's younger sister had come for a visit.

"Why the hell did you hide, you shitty brat?"

"When Misaka saw that person, Misaka's underlings told Misaka to avoid her until certain conditions are met, Misaka explains as Misaka hugs her self in fear."

"What conditions?"

"They say Misaka should be protected by the Original, Onii-sama, and you, at least in the initial meeting, Misaka reports the Sister's advice as Misaka examines the room and its occupants."

"Dam it! Then there was no point in me hiding, was there?" Accelerator gave 20001 a glare.

"Erm, who is this?" Saten asked.

"I am Last Order, Misaka Misaka introduces herself."

"Are you Misaka-san's younger sister?" Saten immediately asked.

"Saten-san, that's rude suddenly asking a question like that."

"But-"

"Yeah, she's the youngest of the Misaka Sisters," Accelerator answered.

"I didn't know she had any younger sisters; I thought she was an only child."

"No, she has-"

"Two," Last Order supplied, holding up two fingers.

"Two sisters, the youngest of which is Last Order. The Railgun is the oldest and then there is the middle sister."

"Umm, how do you know so much about Misaka's home life? We're her friends, and we've never heard about any of this before."

"It's complicated, but right now I'm taking care of this little brat."

"Huh? But-"

*Grooowl*

Saten was interrupted by the sound of a stomach rumbling.

Turning to the door, they found a white robed nun leaning heavily on the door frame, holding her stomach.

"Hungry." She said this single word.

"Ah, it's you!" Accelerator shouted.

He recognized this white clad, silver haired nun as the girl he fed a few weeks ago. In one sitting she went through his entire wallet. The white haired boy was lucky he wasn't in debt after that.

Similarly, the nun seemed to get a second wind from spotting him, pointing and shouting his line back at him. "Um, ah, what did Touma tell me I should say in this situation?" she mumbled to herself, adopting a thinking pose as one arm folded and the other's index finger rubbed against her forehead. "Ah, that was it! Thank you for the meal." And then her stomach rumbled again. In response, she added this line, "I would be most happy if you would treat me again."

"Food sound like a good idea. How many people will there be? Misaka asks as Misaka plots."

"Erm, if Misaka-san and Kamijou-san end up here like they planned, it should be nine people in all."

"Understood, Misaka cheers as Misaka sorts out dinner."

"You didn't?" the Level 5 asks rhetorically. Last Order smiled at him. "You did," he sighed.

*BiriBiri*

Touma just barely managed to block the electric attack with his hand as he ran. Misaka was chasing him with all her strength, throwing arcs of electricity every so often.

Strangely, this didn't feel awkward in the least, running and blocking at the same time. He should have found it difficult positioning his right hand in a way that would ensure the lightning bolt would hit only it; he had to twist his body, redistribute his weight and continue running all at the same time. It just seemed to come naturally, like the first time he remembered meeting Misaka; it was like his body moved on its own.

This time Touma knew it was his fault though. Well, sort of his fault.

Walking towards the Branch Office, Last Order had suddenly grabbed Accelerator's arm and pulled him into a nearby alley. Touma hadn't noticed until they were already gone.

It was then that he noticed Misaka; she was on the floor as though she had tripped on something. Using his amazing power of deduction, he realized that this was one of the clones.

"Ah, Misaka Imouto," Touma greeted as he approached, "are you alright?"

She gave him a bewildered look for second, before adopting her usual expression. "I- erm, Misaka is fine, Misaka reassures."

"That's good, here let me help you up," Touma gold her, offering her his hand.

She took it gratefully, but didn't stand. "How did you know Misaka wasn't Onee-sama, Misaka enquires?"

Touma eyes glanced downward, and a little red coloured his cheeks.

This didn't go unnoticed by the girl still on the ground. Glancing down herself, she realized with a start that her skirt had hiked upwards revealing her panties. She pulled it down so it was covering her as she finally pulled herself up. She didn't release the hold on his hand.

"I see, Misaka sighs. And how do the contents of Misaka's skirt allow you to tell the difference between The Sisters and Mikoto?"

"Erm, ahh," he stumbled.

"You will answer me," a pause, "Misaka presses." She was giving off sparks now; Touma was lucky it was his right hand that she holding hers, otherwise he would have been shocked already.

The blush intensified. "Erm, Misaka always wears shorts under her skirt, and you guys don't," he finally admitted as the sparking intensified and her hand began to squeeze his painfully.

"I see. So not only have you been looking up my skirt, you've been looking up the skirt of my little sister's too, you pervert!"

Touma blinked. "Er, are you by any chance Mikoto?"

"Damn right I am! I go one day without my usual shorts, and this happens. I expected Kuroko to notice, but I never would have expected this from you!"

"Hey hey, hold on. I don't intentionally look up your skirt, it's just whenever you kick that vending machine. I'm really sorry!"

"Oh, and what about my sisters; how have you seen under their skirts?"

"Ah, umm, well, it was an accident, I swear!"

"You bastard! What kind of excuse was that?" she yelled again, the sparks she was letting off increasing in intensity.

Touma tried to run, but she was still gripping his hand like a vice. She looked to their entwined hands when she felt him tug. Then she seemed to take note of her surroundings for the first time, and the people who passed.

"A lover's spat, maybe?" one passing girl suggested to her friends.

Immediately, Misaka blushed and recoiled, loosing her grip on him.

Not one to look a gift horse in the mouth, Touma took off at full speed.

"Hey, come back here!" Misaka yelled as she began to run after him.

This was how Touma found himself in his current situation, i.e. running for his life.

Ducking into an alley way, he was hoping to find a shortcut and double back to Judgement.

Unfortunately, with an oomph, he ran into the leader of a small gang. There were only three of them, which was too many for Touma.

"Hey you little bastard, you better apologize for that, you could have really done some damage. Ha, I reckon I could have been seriously hurt; you better give me some-"

Touma tuned the rest out, even as all three began to advance on him.

"Sorry," Touma gave them a solemn nod, one hand raised in a pray, before suddenly pushing past all three. "Sometimes sacrifices have to be made, and you'll do nicely."

"Huh?" they were about to give chase, when they heard the sounds of a female voice.

"Oi, did you guys see a guy with spiky black hair run past?"

"Hoho, I'll tell you what Ojou-chan; if you pay me, I'll answer your question," the leader of the three immediately changed targets. The boy was long gone anyway.

"And if I don't give you anything?"

"Well, we'll just have to take it by force, won't we boys?"

Misaka sighed. "Geez, you guys never seem to learn."

And with a burst of electricity, the thugs were downed easily. Annoyingly, when Misaka emerged from the alleyway, it was onto a crowded street; there was no sign of her prey.

"Damn him! He always runs!" she shouted out, stomping angrily toward her original destination, the Judgement Branch office.

Cautiously, Touma peeked into the office from the open door. He was breathing hard and was rather sweaty, but he ignored that. Knocking on the door frame for politeness's sake, he headed for the area where he could see Accelerator's white hair, as well as four girls, Index and Last Order included.

After introducing themselves, the group proceeded to chat; well, apart from Accelerator, who stayed silent.

Much too soon though, Last Order let out a squeal of delight. "Onee-sama is on her way here, Misaka informs as Misaka lets her happiness show at the thought of seeing Onee-sama again."

"Misaka's coming here!"

"Yep," Accelerator gave Touma a cruel smirk, "I hope she's forgive you for saying whatever it was you said to her that pissed her off so much." These words did not contain a hint of sympathy; instead they contained an indescribable amount of mirth.

"I don't know what you're so happy about!" Touma snapped. "What do you think her first reaction to seeing you will be!"

That wiped the smirk off Accelerator's face. "I've already decided what I would do if I was forced to meet her. I hid before because I didn't want to confront her, but it doesn't seem like I have a choice."

"Er, what are you guys talking about?" Saten asked.

"Grown up things," the Level 5 snapped.

"Hey! I'll hav-" Saten began, but further conversation was cut off as the door slammed open to a grumbling Misaka.

"That bastard! Always always- What are you doing here?" Misaka hissed as she spotted Accelerator.

Sparks immediately began to burst forth from all over her body, singeing her surroundings.

She saw nothing else in that room but he, the white haired demon that killed 10031 of her Sisters, all for the idiotic goal of reaching Level 6.

Without hesitation, Accelerator dropped to his knees and bowed his head to the floor. "What I did was unforgivable. I submit myself to your punishment."

These heartfelt words just seemed to make Misaka angrier. "Punishment! Ha, like anything I do to you would equate anything you did to them!"

Even as she yelled out, a bolt of lightning fired and hit him, causing him to convulse. He didn't scream, or even move from his position.

"ARGH!" Misaka screamed louder.

She hated him with all her being. He killed so many, and now, now he just bowed down to her and that was supposed to make everything better? So she did the only thing she could do. She sent another bolt of electricity his way.

She wanted to hurt him! To make him feel even one iota of the pain they must have felt as they were slaughtered en mass.

Except this time, the bolt was blocked.

Her eyes opened wide at the sight of him. Her black haired saviour was stood over Accelerator; his clothing was black and dirty from the attack he took head on, without using that strange power of his.

"What are you doing?" she shouted out, distressed. She never wanted to hurt him, even with all the times she threw her electricity at him. She knew he could block it, so it was a non-issue. But now, he was hurt, just like that night when he had taken all the power she could muster, and then told her she was a good person.

How could he do that even as he lay smoking on the ground.

And then he went and risked his life for her and her sister's. And why? She never did ask, although after a few more incidents she had begun to understand. He did it because he felt it was the right thing to do.

So why? Why was he defending him?

Then he raised his head and looked into her eyes, giving her a small, sad smile.

"Why are you defending him?" she cried out.

Slowly, without saying a word, he approached her. And then he hugged her, holding her close.

She unintentionally let out another all body spark, and she could feel him tense up as it shocked him, but didn't let go.

"Do you really think zapping him will make you feel better?" he finally asked. "It won't help either one of you. You'll just be sad and regret it, while he'll just take it as a deserving punishment."

"He deseve-"

"Look at him closely," he commanded gently.

And so she did. He was still bowed, but now that he was looking up incredulously at them, she could see his eyes. They looked so sad and full of regret. He wanted this; he wanted to be punished and atone.

But what really surprised her was the little girl who she hadn't even noticed until now. That little girl who she had only very briefly met once and she didn't even get her name.

It was obviously one of her clones, if much too young. She was stood over Accelerator with her arms spread wide, offering him her protection. She was freely crying.

"Wha?"

"That is Last Order, and though I don't know the details, she is under his protection. They're living together now, along with one of the teachers at my school. Apparently he even took a bullet to the brain for her; he was willing to die saving her," Touma whispered to her.

"Onee-sama will not hurt Misaka's saviour, Misaka declares as Misaka refuses to let more harm come to him."

"This is how he is atoning for his sins, by looking after her. She really cares for him, and though he doesn't show it, he really cares for her too. You don't have to forgive him, but neither should you needlessly attack him either."

For the first time, Misaka noticed she had been crying into Touma's shirt. As she pulled away, rubbing the tears form her eyes, she asked, "Do you really believe that; do you trust him?"

"I have faith that he'll protect her."

"Alright. I may not trust him, but I trust you," Misaka relented.

Disengaging herself from his embrace, she made her way to Accelerator.

Last Order continued to block her path. Kneeling down so that their faces were level, Misaka gently put a hand on the little girls shoulder.

"I'm not going to hurt him."

"You promise? Misaka asks as Misaka renews her resolve."

"I promise," Mikoto nodded. Behind her, Touma nodded in reassurance.

Ever so slowly, Last Order stepped away.

Accelerator was still on the ground; he hadn't moved form his bowed position.

"Get up!" Misaka demanded. "I can't stand to see you on the floor like that!"

Slowly, Accelerator complied.

"I can never forgive you for what you've done. But, you are looking after Last Order. Keep her safe, because if you don't, I'll kill you."

Slowly Accelerator's expression morphed from uncharacteristic anguish, to his usual sneer. "Like I need you to tell me that."

Slowly, the three other girls in the room turned to each other, having watched the whole affair in shock and confusion. "What the heck was that about?"

Whatever it was seemed to be over.

A/N: I'm not sure if I've done the Misaka/Accel scene very well to be honest. Accel may seem OOC, but he is being confronted by Mikoto, one of the few people who truely have reason to hate him, especilly as it regards to the Experiment, which he is deeply regretful of.

I hope you guys approve.

But don't think its over between them just like that. Tensions will be high.

Okay, I don't really want to bump think fic up to M, so I ask you, do any of you mind major swearing? Because frankly, I feel I'm holding Accel back with this level of foul mouthedness. If you guys don't mind more swearing in a T story, I'll probably increase it, but if you do, I'll make sure to only keep it at this level.
