An event that occurred during Tedashii Hamasaki day with Akahana Yoko.

Within the southern end of School District 7 lies Garden of learning. Just like other districts of Academy City, it was composed of schools and other establishments, shops and restaurants alike. However what makes the difference was the five elite schools for girls and establishments that tend to it's population in similar high-classed. One of these top five classes of Academy City high-classes rep building was a prestigious girl's middle school known as Tokiwadai Middle School.

At the same time it is known to be the top all-girl's school in the world.

Among the students of Tokiwadai middle school a certain judgement member esper, attend her study class impatiently tapping the desk with her fingers.

"Just two more classes until I get to see my onee-sama." A girl with tawny hair tied into two natural curly pigtails, tied in place by a red bow each side. Wearing a uniform consisting of a short-sleeved white dress shirt worn under a light brown vest with the school emblem on the left side, and a dark tan pocketed skirts that reach halfway down her thighs. She mumbles away staring at the clock.

"Mrs. Shirai Kuroko, do you have any answers in regards to my questions." The teacher said, staring along with the rest of the class at the young girl.

The girl's pigtails cartoonishly shivers along herself as the classroom begins the giggle.

"Chmm! Hmph... what was the question?"

"What is an Esper?!" The girl's teacher said repeatedly, raising her voice and placing her hands on her shoulder.

"An Esper, is an individual who emits AIM and also someone who enrolled in Academy City's Power Curriculum Program. AIM is emitted by every esper and their power relates to the properties of their AIM.

"And what would an AIM be?"

"AIM is An Involuntary Movement, where an esper involuntarily emits an invisible energy field from their body, known as An Involuntary Diffusion Field that is closely connected to the Personal Reality that is the source of their ability, it is an esper's unconscious interference with reality. A Electromaster's AIM diffusion field, in the form of electromagnetic waves, causes certain electronic machinery like wind turbines to move. Furthermore this esper has a personal reality, which is the basis of her abilities and capacity to substitute reality with her own."

"Her?..." the teacher sighed at her answer, then nodded and said, "Well you're not wrong, and Personal Reality?"

"Reality of oneself! It's the term used to refer to the reality created by us students who went undergo the Power Curriculum Program, and replace normal reality and making our own! As the name states, it is a type of reality that is unique for each individual, and is the very foundation of an esper's power, specifically, it is the source from which all esper powers and phenomena are brought into the real world."

"That is correct mrs. Shirai, the concept of Personal Reality is related to quantum theory. It enables the esper to ignore the Uncertainty Principle and with regards will allow them to interfere with and distort the microscopic world using different laws. This is so the esper can control their microscopic observations of the world​​​​ and actualise the possibility of their choosing. This idea is contrast to that for one who is cut off from proper reality and achieving one that differs from ours. With that delusion, preconceptions believe strongly enough, so will the esper's power improve."

"Mrs. Haru!" A student aside from Kuroko said raising her hand into the air. "Everyone here in Tokiwadai is at least level three and above. I'm pretty sure we understand how esper abilities work and functions. And besides if I could make it to this school with a confusing ability such as mine then anyone else can handle their abilities. Then not to mention we have two level 5s."

"Ah yes, little mrs. Ren Hiroto, before coming to Tokiwadai, you were able to reach level 3 with your ability fifth direct, an ability that applies Its own set of fundamental force laws going by the idea of the hypothesis Fifth Force. You managed to level up after studying string theory, and Yukawa force."

"Mhmm! I'm capable of changing the reaction towards the things I throw at other obstacles seconds after my AIM touch that said object! I know I'm pretty cool!" The girl said, sticking her head high.

"Oh Geez..." Kuroko said, rolling her eyes.

"And that's nice miss Ren, but..." the teacher added. "But is that all?"

"Huh?" Hiroto paused and looked at the teacher dumbfounded."

"Have you tried studying the Kaluza–Klein theory, where the universe has extra dimensions, or in supergravity! Let's go even bigger like the theory of supersymmetric large extra dimensions! Dimensions with size slightly less than a millimeter. Not to mention you're still looking too small of your ability, miss.Ren! You're still applying the existing laws of fundamental force rather than a non existence answer. Think of the #2nd rank esper Dark Matter, the young student uses matter that does not exist, so for matter that does not exist operates under laws that doesn't exist. What you need to do, miss Hiroto is to look deeper into science! Science is the hypothesis to aim for a new answer not an already existing one!"

"Uhhaa! Okay mrs. Haru!! You're absolutely right!!" Hiroto lower her head bowing to defeat.

"Tete, opps I think I overdid it."

The bell rings as the students begin to pick up their bags and head out of Mrs. Haru's classroom.

"Finally!" Kuroko got up and grabbed her bag heading out of the classroom.

"Mrs Shirai, before you go can I have a word with you?"

Kuroko sighs and grinned as the other students left out the front door.

"Don't worry I'll make it quick." Mrs. Haru said smiling. "It's about your little obsession with your roommate the level #5 railgun Mikoto Misaka."

"Obsession?!! It is not an obsession!! It's genuine love for my Onee-Sama! How dare you!!"

"I see... sorry. I just put two, da two together from your impatient look to the analysis answer of an esper ability. And I came up to the reason why you're having trouble improving your esper ability."

"Excuse me?"

"A personal reality is of oneself not another, you cannot learn or progress your esper ability if you get your mind locked upon the railgun. I think the railgun would be fine after all she is a level #5."

"But mrs. Haru! How can I turn my back towards Onee-Sama! She needs me more than you think! Especially now more than ever!! Last month she was super depressed and it's been around the same time some ape appeared into my sights!!"

"And what about you?"

"What about me! What about Onee-Sama!! I have to.."

"And that's what I mean, you have your entire personality wrapped up on, the level 5 without leaving any room for Shirai Kuroko. How are you supposed to develop and improve your esper ability?"

"...I'm a level 4 though."

"And you could reach level 5!"

"I don't think it's that easy."

"You'll never know."

"Mrs. Haru! I could never reach the power level of Onee-Sama. She's the greatest of Tokiwadai! And the Electric Princess, Tokiwadai's Ace! Number three and most importantly the Railgun! I want to protect her status, not disgracefully surpass it!"

"But don't you want to stand by her side?"

"Well...yes but."

"Shouldn't you get strong enough to stand by her side?"

"But I'm already..." Kuroko pauses and thinks back of the mysterious that surrounded her roommate last month from her late rounds, and the lies she had to carry from their dorm supervisor. She never figured out the events that conspired during August 22 but she knew one thing: that certain mysterious ape did something that night and fixed it. Something she couldn't do.

"I just want you to take that to consideration, we still know so little of teleportation. So we need you to focus a little more on yourself."

Kuroko sighs giving in and then nodded.

"Good! I just want what's best for you." Mrs. Haru said, placing her hands together with Kuroko's hands. "And besides we don't need some Esper five days from now with the same ability as you, surpassing you in the Daihaseisai Festival.

"Hmph like anyone would! And besides you forgot I'm a member of Judgement as well I'm the top skill teleport esper out there!" Kuroko free her hands from Mrs. Haru and stormed off.

"Mrs. Haru pokes her head out her classroom door waving and says, "Alright then! Mrs. Shirai you have at least two days to show me some improvements, don't forget these the last two days before my transfer.

"Finally!" Kuroko said trilling running up on a curriculum esper exam for what's next. "tete I won't be right next to her but I will be near her feeling the embracements of her power!"

Girls of science set up side to side displaying their esper abilities.

"Girls get your gears straight and your minds moving. I need new ideas! I need the best that you can ever be! Take that drift into second gear!!" The student's coach under the microphone blurted continuously among the field.

"Geez, can she give it a break, we get it! The Daihaseisai Festival is in a few days! Kuroko said growing waiting among the branches with other girls.

"Careful Shirai, coach been looking for you." Ren Hiroto appeared before kuroko sitting next to her. She giggled at Kuroko's cartoonish shiver.

Kuroko came to her senses and rolled her eyes then glared at the young girl. "Can I help you?"

"Entertainment from you as always, what ask for. So Mrs. Haru had a talk with you so what was it about?"

"Why do you care!"

"I was just saying you know it's her last two days here of course she's gonna be try-hard again this week."

"Oh is that why she asked you to say after and talk with her after class yesterday."

"Eh, owww!! Hmph!" Ren snapped and turned away from Kuroko crossing her arms.

"Hmph!" Kuroko raised her head high, smirking." Kuroko's name pops up on the electronic board display. "Well I guess it's my turn then. Kuroko heads into the front center of the field.

Kuroko set up her gear then analyzed the position. In order for Kuroko Shirai to use her ability she must find the 11th-dimensional position of the object of interest and then calculate the vectors to move. The calculations are more complex than the commands of regular espers, and she must maintain all signs of focus even being slightly distracted by anxiety, confusion or pain would disturb her formulas.

"Okay well this shouldn't be too hard." Kuroko thought to herself. "81.5 meters is my best score so aiming just a bit more should suffice the case. Kuroko took a deep break, grabbed on the iron plate and concentrated all her dimensional calculations. But suddenly a thought of August events blink upon her imagination.

Record...
78.23 meters

"Tsk, a calculation error..." Kuroko mumbles to herself.

Overall score 5/5

"Ahh," Kuroko said scratching her head, annoyed. That's a high phase for really bad conditions. You know I'm not good at moving large or heavy objects that far. If it had been around 50 meters then the correction error would be in millimeters.

"Ufufufu! Are you worrying over the numbers that determine your ability Shirai-san!!"

From behind Kuroko, an attractive girl waves her prominent forehead which is flanked by two fringes of her black hair, long and kept neatly around with a smirk.

"Kongou Mitsuko..." Kuroko confirms herself to the girl who snuck up on her. Just one messy girl after another she thought to herself. "A person's prettiness is greatly exposed when they laugh at another's bad conditions."

"Well, well." Mitsuko waves her fan brushing around, "I will offer to send you some good wind, so please don't sulk."

"It is none of your concern."

"Not at all. You see this time I will be starting a clique."

"What would you think about joining it, if you would like to Shirai-San?"

"Certainly cliques are often started at Tokiwadai. And these cliques hold great power not just limited to the school. However it's safer to stop. If you start a clique it will get annihilated within minutes." Kuroko said looking back at Mitsuko with a tensive glare.

Mitsuko balled up her fist a little imitated, she barked, "Excuse me?! You must have not realized mine newly planned Clique will have a shot! The Kongou family and my own abilities combined is more than enou-"

Whoosh!!

A sudden quake erupted as if it was an earthquake. From afar the girl's arena.

Mitsuko fell and flopped over the ground. She looked back horrified by the gushing water lunch from power along.

"Wha... what was that?!" Mitsuko said in disbelief. "That can't be a human being?"

"Oh! Ho Ho Ho!! But it is?" Kuroko announced, "Kongou-San since you transferred into the class during the second semester you may not be familiar with her but...

"Just know if you make a clique for your own selfishness Onee-Sama will Immediately stop you." Kuroko nodded with a smirk.

"...Oh ... is that right..." Kongou gulped with a quick change of heart.

Mikoto Misaka is my Onee-Sama. She is the strongest esper ever! I love her with all my heart... but I didn't know everything about her, my Onee-Sama is hiding something from me... and it's no Gekota prop... it's something else a certain secret.
