[In a certain alleyway]

"This is it! This is the best!!"

The glasses student by smirking, thinking to himself,"With this device, my ability had become stronger and stronger!"

"I only need to dispose more of those useless Judgment, and those deliquents bastards are the next one!!"

"And soon, my ideal world would be finish—!", suddenly, someone kicked the glasses student from behind.

It's revealed that Mikoto was the one who kicked him,"Hei~~!"

"I don't need even to explain why I'm here right, Mr. Bomb Maniac?"

This glasses student is surprised,"Wh-what are you—?!", then another person is arrived,"You can stop pretending now, Mr. Hatsuya Kaitabi from Minato High"

It shows that the person is Mugi, causing Hatsuya to panic,"Are you doxing on me?!"

Even though she shows to be calm, Mugi unleashed a threatening aura,"You shouldn't underestimated my Kotobuki's network connection power(I)", causing Hatsuya to flinched,"Y-you're with Kotobuki?!"

"You see mister, the explosion was indeed something", said by Mikoto, and she added,"But it's too bad"

"Forget about injured person, nobody is have any scratch on them"

Hatsuya then exclaimed,"Th-that can't be! I even used up my maximum capacity!!"

"Oh~?", said by Mikoto, suspicious towards Hatsuya.

In panic, Hatsuya tries to distract, while secretly takes something,"I mean, I thought that kind of explosion would really causing the people inside are unable to do anything"

When Hatsuya attempted to use his power, but Mikoto shoot a railgun before he can do anything.

"Ra-railgun?!"

As Hatsuya about to run away, Mugi uses her abilities to hold him.

Thud!

"My, I'm slipped my hand to the point to used Gravity Point at your feet earlier(1)!", said by Mugi pretending to be sorry, while Mikoto restraining him on the back,"You can struggle, but I can't ensure your safety"

Hatsuya suddenly stopped struggling, and stated,"Hahaha, now the person of Kotobuki family and Ace of Tokiwadai are the ones to put me in the corner?"

"It's always like this... I'm always the one that ended up to be crushed like this"

Then, Hatsuya glared hatredly to Mikoto and Mugi,"I'll kill you all!! It's all your fault!!"

"Those Judgment members are not help me when I was in trouble, unless they really saw it!!"

"And you two are not differents from those deliquents bastards!!"

Without any word, Mikoto grab him from the ground and face him,"It seems you have your own circumstances. But, don't get carried away!"

"The one in front of who facing you right now is the one that starting of from Level One"

"And I've had to worked hard to achieve the Level Five, when the people around me are struggling to do so"

"But as for your information, even if I still remained as Level One, I'd still gonna stop you", then Mikoto punched him.

Smack!!

When Mikoto leaving Hatsuya unconcious, Nodoka arrive with two Anti-Skill members.

While the Anti-Skill take the unconcious man into their custody, Nodoka said to Mugi,"She really have no mercy on criminal, huh?"

"Mikoto-chan had already did what I want to do to him", said by Mugi, with sweatdropping face. Then, she turns to Nodoka,"Thanks for the hard work, Nodoka-chan"

"Well thanks, althought I kinda regretted to navigated Misaka-san too with my ability", replied by Nodoka.

[Outside of Seventh Mist]

"So the reason you separated yourself from us earlier was to looking for Ui-chan?!", exclaimed by Mio and Ritsu to Yui.

Yui then sweatdropping,"Ahaha, that's right...", while her little sister bowing her head,"I'm sorry to make you all worried!"

All of sudden, Azusa approached Yui. Her senior tilts her head for confusions,"Azu-meow?", but she just clenching her fist,"Senior, please forgive me in advance"

"Sure, but what for?", as Yui in her questioning state, Azusa smack her senior head.

Thud!

"Ouch!!"

"Azusa-chan, what are you—!?", before Ui finished her sentences, Azusa shows her outburst,"You're the worst!! Why didn't you asking our help about Ui?!"

"Are we not reliable enough to you?!"

While rubbing her head, Yui stared at her junior in guilt,"... Azu-meow..."

On the other hand, Ui stunned on Azusa's words,"Azusa-chan..."

As Yui approached her junior, Azusa just throw her face away while closing her eyes. But to her surprised, Yui just embracing her,"... I'm sorry, Azu-meow..."

"Sorry to make you worry about me"

On the other hand, Azusa accepting her senior apology,"Good grief..."

While Yui is doing that to Azusa, Ritsu lightly hit the carefree girl's head,"She's right, so I'd gonna say that you deserved that punch"

Mio sighed, but smile in agreement,"You're right"

Ui apologizes to Azusa,"Once again, I really am sorry about that"

_

"Ah!"

Five of them are startled, and Ui asked,"What's wrong, big sis?"

Yui panickly looks around her, and suddenly running away, leaving her friends and her sister confused then following her.

"Hei, wait!"

As for Mugi when she spotted them running past her, she's doing the same as the other do.

_

"Well with the culprit now is taking into custody of Anti-Skill, we can say the problem is solved right, Misaka-san?", said by Saten to Mikoto.

But Mikoto however,"No, we're missing someone else here"

"Huh? What do you mean by that, Sissy?", asking bu Kuroko.

Without any words, Mikoto walking away. This is leaving her three friends no options but to followed her.

"Misaka-san, wait for us!", said by Uiharu.

In the late afternoon, before the curfew announcement begin, the scene takes place at the old drink vending machine area.

When the guy is walking all alone, there is someone who ran while calling him from a distance,"Hei!!"

The guy is stopped, and it revealed that it was Yui Hirasawa that approaching him, with her four friends of the Light Music Club members and her little sister Ui following her from behind.

Upon Yui catching her breath, Ritsu asking to her,"Why did you suddenly run away? Do you need something from this guy?"

"O-of course I am! This person was the reason that I was able to saved Ui in the first place!", answered by Yui, explaining her reason.

Azusa confused about this,"Huh? What do you mean, Senior Yui?"

From his other side at the vending machine, Mikoto suddenly appeared with her three friends.

"Hey you, why won't you name yourself as the hero? Since you were the one that actually do that, not me", said by Mikoto.

Kuroko is confused,"Huh? Sissy, are you serious?"

"Even Misaka-san...", said by Mio, that felt being in the dark with the others at the statements from both Yui and Mikoto.

"Big sis, could you please elaborate it?", said by Ui, to her big sister.

Yui as her response,"Um, well... Actually I just remembered it from today. About a month ago, I've saw this person was pretending to be Mikoto-chan's friend, and attempted to took her away from the deliquents(2)"

"But in the end, Mikoto-chan was somehow pissed off and fried the people around her with electricity—including my new digital camera"

"And this person, I remembered saw him somehow survived the electricity with his power"

Yui then explain what had happened when the two graviton bombs are about to exploded a the mall,"In summary, this person was the one that gave me the idea of how to defended Ui, by erased the explosions with barehanded power!"

With a moment of silence, Ritsu suddenly break it comically by touching Yui's forehead,"Hm... You're seems to not caught a cold..."

"Ricchan, you're so mean! I'm just telling you the truth!", exclaimed by Yui.

"On behalf of my big sister, I'm thankful to you that you were there the reason my sister could protected me, sir", said by Ui, bowing her head to show her gratitudes towards the guy. Ritsu however,"You're judge it way to fast, Ui-chan!"

_

"No offense, but what kind of power of this seems to be ordinary guy that caused you to be able to protected your younger sister?", stated by Ritsu, as if demanding for explanation.

But Yui with her airhead answer,"Dunno", causing Ritsu to irritated and choke her.

Then, the guy is breaking the atmosfer,"Why do you guys care so much?"

"Eh?"

The guy just simply stated,"In the end everyone are saved, so there's no problem, right?", then he just walking past Mikoto and her friends with humming to himself.

While everyone are dumbfounded with his attitudes, Mikoto is red-faced and pissed off, then kicking the vending machine repeatedly.

"Don't messing around with me!! Why of all people, it have to be you to acting so cool?!"

One of the canned juice are come out from the vending machine, got flying into his foot, causing him to slipped.

As the guy got up, he sense a dangerous sense behind him and murmuring,"Such a misfortune...(II)"

Then he saw Mikoto are activating electricity around her body, still with her red face.

The guy took a step back by sweatdropping, and said,"Zapper, I don't see why do you need to do this"

Mikoto is become more furious,"How many times I need you tell you, my name is Mikoto Misaka!!"

Then Mikoto unleashed a powerful lightning strike towards the guy.

Crash!

But the lightning strike was shatterred like a broken glass, when it touched his right hand.

Everyone that witnessed this, aside from Hirasawa sisters and Mikoto are surprised. The guy without anything left to say, just running away from the scene.

"He just erased it... with barehanded!!", exclaiming by Saten with awe.

Yui then innocently asking Mikoto,"You seems to know him more than I do", and as the response,"I've fought against him a lot for couple days ago, but never managed to beat him at all despite he's a Level Zero"

At this moment, Mugi asking(III),"Do you know his name?"

"No, I don't", answered by Mikoto, causing Yui to blatantly stated,"You're angry when he's not called you by your name, but you're not do the same to him?"

Azusa noticed something on the ground, and picked it up.

"Isn't this his student handbook?"

Curious about what it said, Yui read it aloud from behind her junior,"It seems his name is Touma Kamijou"

"Touma Kamijou... What a weird name", commmented by Ritsu, and Mio responded her,"Like you're the one who talk"

"Because you know, that guy's name seems to have a meaning like 'Kamijou' is stands for 'Above God', and 'Touma' is stands for 'Invisible demon' ", said by Ritsu.

With her scary yet teasing tone, Ritsu adding,"When you combine those two names together... the meaning is 'The one who purifies God, and exorcises the devils(3)'... That's right..."

"That Kamijou person, maybe..."

"Would use his right hand to exorcising the demon right besides you, Mio!!", exclaiming by Ritsu in her sudden high voice, which is caused Mio to scream,"Whoaa!!"

Smack!

"Ouch..", while Ritsu rubbing her head after being hit by Mio, with Mugi embracing Mio to calm her down.

Regardless of the comedic skit by Ritsu and Mio, Uiharu give it a thought about something.

On the way back to Sakuragaoka's Dormitory Building, Yui asking her little sister.

"By the way, what were you doing at the Seventh Mist?"

And she answered,"After I've visited her at hospital, I noticed that the Seventh Mist are nearby. So before I went home, I thought that I could stop by for a while to buy groceries"

"Ooh, so that's why...", said by Yui, understood the reason.

Then Yui changed the topic,"Anyway, what's for the dinner?"

"We'll have some curry, big sis!", replied by Ui.

All of the sudden, Yui cheerfully singging,"A bit of curry and plenty of rice~(4)!", and Ui giggling at her sister antics as they walking together.

Later on, in a certain convenience store at the first day of the summer break, Mikoto happened to bump into Nodoka.

"Oh hei there, Manabe-san"

Nodoka replies,"Hei there"

In a moment, Mikoto seems to hesitates about something. But Nodoka, breaks it,"You seems to wanna ask something"

Mikoto is nodding,"... Let's go somewhere else to talk"

_

Meanwhile at the same time in a certain Family Restaurant, Saten, Uiharu and Kuroko are waiting someone to meet up with them.

"Sorry I'm late!", said by someone, that revealed to be Ui Hirasawa.

Saten reassure her,"No it's fine, we're just here too"

_

"Why here?"

Then Nodoka replies,"Aren't you the one that wants to ask about Yui?"

"Well that's true, but... why it have to be the hospital?", asking by Mikoto.

Nodoka gives her reasoning,"It would be better if you heard it from the experts"

_

At the Family Restaurant, Saten asking Ui,"Now, what is Yui-san's doing?"

"She is just laying around the dorm, since she's not good with the heat of the summer", aswered by Ui.

"Such a carefree person", commented by Kuroko, then she said,"But let's put aside the small talk, because there's something caught my interest about your big sister"

"Eh?"

_

[The hospital A]

As they walking at the hall, Nodoka caught a glimpse at one of the name plate of the patient room but didn't stop in her track. Mikoto noticed it, but decided to keep silent.

Upon the time they arrived, Nodoka knocking the doctor's room, known as Heaven Canceller.

Then, Nodoka greets him,"It's been a while, doctor", while Mikoto however exclaimed on her thought,"He's Gekota in real life!", due to this Heaven Canceller face really is similiar to the Academy City's frog mascot—known as Gekota.

"Oh it's you, is there something I can help with?", replies the Heaven Canceller.

Nodoka explained,"Apparently she wants to know what is hidden ability about Hirasawa sisters"

"I can explanate her about it, but I think it's better comes from an expert like yourself, sir"

"Okay, why don't you two come in and take a seat", said the Heaven Canceller agreeing and let them in.

From the hall, there is Touma that had just walking around it saw they went inside an office.

At first Touma was intended to go inside, but he felt that he can't do that. So, he decided to stay nearby the office.

[Inside the office]

"Now, what is it you want to know?", said the Heaven Canceller to Mikoto.

Mikoto then replied,"Could you please explain to me what kind of power that the older one of Hirasawa sisters have?"

Heaven Canceller then explained,"To be fair, the older one of Hirasawa was not the first Level Zero esper that have 'special condition'. In fact, the probability of her state to possessed a power is like 1 in 1000 cases"

"There are sure another Level Zero espers that have exception like herself(IV)"

"The first time that we found it odd, because at that time when this Hirasawa girl's class was doing her first System Scan along with her classmates, she was just like mimicking the other people esper abilities. But when she got checked just all by herself, the results are zeros"

"And thus, the scientists including myself are in agreement, that to call her ability in medical term as 'Auto Noise' (V)"

Ability : Auto Noise (自動雑音)

Level : 0 (Zero)

[In the Family Restaurant]

" 'Auto Noise'...? What is that?", asking curiously by Saten.

Ui then answered,"It means that, my big sis could instantly copying any abilities—whether it's conciously or unconciously, by changing her own brain patterns of AIM diffusions field to produce the Personal Reality that it imitates"

"Any ablities... Could it be, the seven Level Fives powers too?", asking by Kuroko, and Ui nodded as confirmation.

Saten then exclaimed,"That's awesome! Uiharu, I can't believe you have such a strong former senior of elementary school like Yui-san!", and her friend just hesitantly agreeing,"Um... you're right"

_

[In the hospital A]

Touma are silently surprised to know about the older Hirasawa's power, and thought,"That would be explain of how she copied my right hand power two days ago"

_

_

[At the street]

In the late afternoon, Mikoto is walking alone. She is checking her transmitter about Ui Hirasawa's ability from the Bank data—the index of espers abilities and its users,"Ui-san's power is Swift Mirror, classified as Level Four"

"She can manipulates her own brain patterns of AIM diffusions field to duplicates and imitate the Personal Reality of other three or four espers, even to the point of reconstructing the molecules of her own body, so that she can change her body into any substances with various specific hardnesses"

"Her power are considered as another 'the next Level Five candidates', but she can't do that considering her health problem was involved"

Mikoto then gives her thought,"It's similiar, yet different from her older sister's power..."

》Character Info《

Ability : Swift Mirror (迅速鏡)

Level : 4 (Four)

_

Meanwhile, Uiharu is have a thought to herself as she walking to her dorm,"Ui-san's power are actually indeed stronger than Yui-san... But...(VI)"

She look back to the memory of her past, that Ui was collapsed on the floor with a difficulty of breathing at a certain room, and shifted to Yui who was tightly embraced her in the hospital.

Then back to the present, Uiharu added,"If she stay in reconstruct molecules's mode more than 3 minutes..."

"She could lost her lives"

(II) Yep, you know who is this guy now

(III) Mugi just being herself, curious about the romantic things (aside from the fact I changed it a bit)

(IV) Yep, and our Touma and one of his friend are at the same conditions with Yui

(V) Now you know what is Yui's power. For the reason I attached this power to her is, because she have shown to able to learn things just by looking, just checking the K-ON! season 1 episode 9

(VI) I have my reason why I attached the weakness on Ui's power, and that is because when she changes her body into a solid substance, then slowly her body has to throw away her human side—including breathing

Others footnotes:

(1) Yep, Mugi's power is allowed her to controlled the point of gravity from anywhere towards the object, without even touching it

(2) Just check it at the A Certain Scientific Railgun season 1 episode 4
