"I'll give you a hint at least. August 21st. If you manage to make it pass that point I'll become friends with you alright?"

"Certainly that day was when Onee-Sama returned late at night... and a certain ape suddenly showed up. After that a mysterious storm blew violently through downtown. Devastating the switch yard in district 17...

"After that... we began to hear the rumor. That Academy City Strongest Level 5 was defeated by someone...

"I don't know what occurred that day but I can only speculate, could have Onee-Sama...

"It does not matter now, I know now what I must do, I don't need to dig and find something wrong with Onee-Sama! That's what they would expect a friend of a level 5 would do!"

Kuroko teleported around searching for all means. But to no use Musujime was completely gone from her sight.

"No... I can't give up! I won't let that ape get one up on me again." Kuroko said looking left and right, suddenly her phone buzzed, a message was sent from Uiharu. Kuroko opens the message only for her phone to get instantly hacked from her surprise. Suddenly an emblem icon with the letters CV appeared. Once the loading finishes, a red dot appears and reappears into a restaurant nearby. "Hmm! So she actually did it. And I didn't expect her to have the courage, however she only did it once and not enough to actually get away. Uiharu, I don't know how you pull this off but I already know where this will lead me to thanks!"

Inside the restaurant Musujime appears teleporting herself. She quickly looked out the window to see Misaka running around in circles losing sight of her.

"Phew..." Musujime saids placing her hand on her chest, taking a deep breath. "She assumed I wouldn't dare teleport myself. She underestimated me...Ugh..." Musujime quickly covered her mouth almost hurling. She bowed her head swallowing some of the puke that escaped her mouth, she quickly snatched a napkin from off the table wiping some of her puke. "If I feel like it... I can still do it. I can still do it... despite what happened...!! Suddenly a sound effect noise ring near Musujime as she suddenly felt a phenomenal happening to her shoulder. She looked to her shoulder to feel a pinch of pain from a corkscrew suddenly appearing in her shoulder stabbing her. "Ahh..."

"Precisely because you can't overcome it that easily? Your trauma that is." Kuroko said, sitting down on a table with a smirk.

"Shirai... Kuroko!! How did you find me!!"

Kuroko frantically nodded and ignored Musujime and said, "It doesn't matter, however I am returning that corkscrew to you. It isn't my hobby to carry Sheffield corkscrews around with me. And these as well." Kuroko slides her fingers against her black strips that store metal spikes. Teleporting the metal spikes into Musujime's body.

"Ah...ch...!" Musujime dropped down on her knees. She looks up at Kuroko as sweat begins to drift from her head, "... You're doing it now...?

"No need to panic I avoided your vitals. Well, I am only returning the attacks you did on me... but if you would like," Kuroko replied, pulling out the same ointment she used for herself in the bathroom, and from her hand she teleports it near Musujime. "Feel free to use this? Go ahead crawl on the floor and treat your wounds. With that we will be even." Kuroko's attacks put fear into everyone inside. Everyone panicked running front center out the restaurant that now became an arena.

"Fufuf... such a childish way of taking revenge... I don't hate it." Musujime saids while making stand from off the ground.

"My, you are much more relaxed than I expected. Is this alright with you? With all this commotion, it won't be long until Onee-Sama comes running through.

Musujime nervously stares at the window for a split second and back at the Kuroko that frantically nodded once more sticking her index finger.

"Don't push yourself." Kuroko saids struggling her shoulders, "It must be quite the challenge to teleport yourself with move point right? Plus... the results won't change no matter where you run. After all, the two of us are tediously similar. In this situation with identical abilities... and with the same handicaps. Wherever you try to run or hide... wouldn't I be able to find you?"

"Tch! You're buffing!!" Musujime waves her arm but the pitch of pain tingles her body. It was there she realized that Kuroko struck her the same way she did so her movements would become more predictable even if she chooses to run. "Bitch!"

"Aw, don't be like that... it's alright as long as I confine you here. But won't you obediently get caught for both our stakes," Kuroko said, getting off the table standing against Musujime.

"I wonder now?" Musujime said, beginning to form a malevolent inspection in her eyes, "If you actually intended for the railgun to get involved, wouldn't you have brought her to begin with? And your sneak attacks just now. If you had aimed this corkscrew to my heart or brain your victory would already be decided. You must really admire that kindly ace of Tokiwadai right... how pitiful. Is it really worth protecting to that extent? That corny and selfish world that railgun dreams of..."

Kuroko balls her hand into a fist and looks at Musujime with unwavering passion, that tense up Musujime, "I want to protect it. Of course I want to protect it... even in these circumstances Onee-Sama still wishes for it. A world where neither you nor I have to fight. If she felt like it, she could smash everything to bits with just one coin. That's why she won't do it. She's trying to save even you! That's why she's carrying a burden she can't tell anyone about all alone. Do you really think that!? I am Kuroko Shirai and I would never trample over Onee-Sama's feelings!" Kuroko wavers her pigtails and swift her arms into a fighting stance. As Musujime wipes out her military flashlight. The two stand against each other in standby phase. "Starting from here, I will return her world to normal with my own hands and protect it!"

"Hm... Then as long as I crush you along with those feelings it's my win."

The two girls stare on the first move and a small reaction could be fatal for both sides. This is how the battle between the string theory works. Kuroko grabbed a plate smashing it against the table near her, shattering it. She charges at Musujime who swift her flashlight right left and up. Kuroko studies the patterns of Musujime's hand movement, then proceeds in finding the 11th-dimensional position of the object of interest and then calculating the vectors to move. Kuroko identifies the plate and fork that Musujime chooses by coordinating its value.
Σp xi =Σp xf
(2) 0.22 0.44 (x2P(0.88)) = 0.26
Square Root (2) = 1.41421356237

That split second Kuroko imagined a Trigonometry to calculate the remaining missing value in her equation.

Kuroko's observation and hypothesis was correct, successfully dodging and evading the teleported plate and fork, "Just as I thought... If I observe the movement of her flashlight I can then proceed calculations. It is possible to dodge to some extent...!!"

Musujime does the same quickly calculating and proceeds to teleport all the tables and chairs within the room above in front of Kuroko's view.

"Trying to close off my view by creating a blindfold again how predictable! No matter how many times you use that trick, I'll see right through it!" Kuroko teleported over to the only to be met with Musujime holding the briefcase swinging at her, with the flashlight in her mouth. Kuroko evades Musujime's close range attacks but to Kuroko's surprise Musujime switches it to strolling gear rolling it and tripping Kuroko down. As Musujime maliciously rises up the briefcase Kuroko throws the shared broken plate from earlier. Musujime assumed the glass was for her and swift her head. But a clicking noise snatched as the briefcase's handle was Kuroko's actual target breaking it. The briefcase sides accelerating towards the corner. As Musujime eyes averted the briefcase she left an opening. Kuroko immediately gets back up and punches Musujime.

The punch moved Musujime's head which had the flashlight wrapped around her mouth. Still focused on the briefcase Musujime calculated the value of the briefcase which was far too easily since she had it the entire time. Teleporting the already sliding velocity briefcase towards the air, lunching at Kuroko's face smacking her into the air as if it was a warped uppercut. As Kuroko's body reacts to the collision her body took in the accelerated force. However Kuroko knows the size of her body was 152 cm, quickly after applying the force of vectors, (1.5200 √ = 1.52) teleporting right from behind Musujime crashing into her back the collision impact knocks both girls from the opposite direction from one another. With Musujime taking in most of the damage. Musujime fling over getting knocked over and up off a table.

Kuroko took in less damage however due to the injury from the corkscrew a while back. Her wounds reopened bursting out blood. "Hah Hah! Kuroko cried out in pain. Kuroko tries to rise back up only to get a view of the angry static look of Musujime's rage.

Teleporting was an advanced Esper ability. The calculations are more complex than the commands of regular espers, and thus Teleporters cannot use their ability when distracted by anxiety, confusion or pain. Unable to do any calculations because of one of these flawed principles Kuroko had to watch helplessly as the angry Musujime dropped a hurled of everything above her body.

Kuroko lies there trapped and defeated once more. Musujime stood strong still in her guarded stance. Musujime claimed down and saids, "Shirai-San. If you don't dodge this you'll die. Musujime dropped a trash dumpster near Kuroko's head, almost smashing her head. Despite screwing up her own calculations from her own pain Musujime, lowered her flashlight.

"I'm not an bad person... these powers... they made me into a monster."

"...Eh...Hmm." Musujime closes her eyes then remise in her purpose once again. "It looks like if you're in a place where you lack space due to huge amount of mass you can't make an equation rendering you from teleporting just like me. Or maybe was it because you couldn't properly calculate due to the pain...? Seriously... it must be troublesome to have such a fragile ability. Hey Shirai-San? I wonder if you've heard this story." Musujime's saids while swiftly waving her flashlight to teleport the spikes that Kuroko stab into her from earlier, then proceeded to take off her jacket that was worn as an cape and rearranging the bandages wrapped around her breast to the wounds of her shoulder and torso. "Long time ago, in a certain place. A powerful Esper organization existed. The organization thought that if they increased the certain number of Espers, they would gain even more power. So they decided to make clones. But even so the results were disappointing... In the end the pitiful clones had even less than a percent the original Esper's power. Quite the failure indeed. Why is that Shirai-San? Why did they end up as an failures? Even though they shared the same DNA and underwent the same Esper Development Curriculum. Have you ever considered that... maybe there's something besides the brain structure involved? If you could isolate that something wouldn't that mean Esper powers wouldn't be limited to humans?"

"What are you saying?" Kuroko said puzzle at Musujime theory. "Are you saying that a personal reality can be used on other organisms?"

"In Academy City, Espers don't use a special extrasensory power called the sixth sense. They observe and analyze reality through use of special intentionally wrapped facilities of calculations and judgement called personal reality. In response to that effect the probability of the microscopic world fluctuates unnaturally, which gives the birth to new kind of phenomenal. Don't you see, how we as humans grasped the appearance of reality... that is essential point in the development program that takes place during the curriculum. The result of observing an analyzing the given information manifest itself in that what we call Esper powers.

Maybe humans aren't supposed to have powers? Maybe we don't know what's best for them. Maybe what happened back then wasn't my fault... maybe those inner demons that I possess only happen when I require powers. It's money... you become greedy the more of it you have thus why the seven Level 5s no anyone who's strong becomes ruthless... in other words it's not my fault how I came to be... it's not my fault of what happened back then. Maybe... maybe...

"But is the human brain the only thing capable of achieving that? If it's just observation of phenomena don't you think that something other than a human can do that?" Musujime continues to ramble on and on about her theory as Kuroko slowly starts to loosen herself. "That's right. For example using something that has the same calculation ability as the human brain."

"That's absurd!" Kuroko shouts out, still slowly gathering strength from her body. "Are you trying... to give Esper powers to a machine? No one would consider such nonsense!"

"Oh but they already speculated the possibility! There's a girl named Akahana Yoko! And her Data Mine Esper ability is quite the unique ability, they say her inner realm of thoughts can change the input source code information even her own personal thoughts! Datamine can give a machine artificial intelligence by this girl!! Once machinery gains that well observation will be invest thus the possibility of an Esper ability!"

"What!?" Kuroko said dumbfounded.

Musujime smiled at Kuroko's reaction then proceeded, "So I thought, and If the rumor about Data Mine potential could possibly be true..., if clones can at least be level 2. Then it's not too much with the Tree Diagram or Data Mine, to possibly predict if specimens which can use ESP instead of humans exist. I want to know that?" Musujime malevolent gaze upon Kuroko.
"That's why...

"Shirai-San." Musujime got down on one knee getting close to Kuroko. "When you first gain your power... how did it feel? Honestly I was terrified having this power in my hands was terrifying. Knowing I can kill someone with just a single thought. Even so I thought it couldn't be helped, at least the thought that my power could be researched and analyzed by others and contribute somehow to this world... that thought kept me going... but if it doesn't have to be a human... if it doesn't have to be me why was I given these powers? In Academy City many children suffer from unstable powers. Those men in suits that I threw around were my friends, so why would I have done them the way I did? It's not my fault Shirai-San. Surely you understand? Being manipulated by monstrous powers that hurt people around you." Musujime looks at Kuroko in the eyes sincerely placing her hands on Kuroko's cheeks. "Surely you thought about it, why did I end up with these powers? I know because we're similar in many ways. How about it Shirai-San if your interested in discovering the truth with us, I would gladly invite you." Musujime beliefs were surprisingly challenged when Kuroko rose out the pile of tables and chairs with brute force. Kuroko rises up with a fierce pierce that frightens Musujime. Musujime takes a few steps back away from Kuroko completely puzzled in disbelief.

Kuroko held tightly to her wound, and saids "I refuse your offer. Did you really think that would convince me, with your delusions."

"Why can't you understand? If it could be prevented that we Espers, turned into monsters!! Before we had this dangerous power..." Musujime shouts, clenching her fist.

"It's not like our powers will disappear, even if you predict this possibility. But how we use these powers depends on us. Are Esper powers scary? You don't want to hurt others? Whether we had powers or not, it doesn't change the fact that you're someone that is willing to hurt others to achieve your goals." Kuroko's words shook Musujime causing her to frantically shake her head.

"No that's not... that's not true!"

Maybe humans aren't supposed to have powers? Maybe we don't know what's best for them.... You're someone whose willing to hurt! Hurt! Hurt! Hurt! Hurt!!

"Shut up!!" Musujime shouts wiping out her flashlight only for Kuroko to have already touched one of the fallen tall lamps lights that was above her and placed it into her hand swinging it at Musujime's hand. The lamp knocks the flashlight light out of Musujime's hand. As Kuroko swings it again but this time towards Musujime.

"Bang!" A sound ring blood burst from Kuroko's side torso. Musujime shot Kuroko with a pistol.

"Aah..." Musujime gasps of what she's done as her thoughts mess with her inner mind. She now had to come face to face with proof.

Whether we have powers or not... it won't change the fact that you're someone that is willing to hurt others... to achieve your goals.

Musujime stared at the flashlight that was now from afar that landed on a table and reached her hand out trying to calculate and bring it to her with move point. But the distortion of poor dimensional calculations causes the table to telekinetic tumble over. With that split second a three second lag caused the flashlight and the table to dimensional travel pass each other before the flashlight was teleported in Musujime's hands. She looks at the blink small scratch caused by that phenomenon causing her to relieve her worst memory.

"No! No! No no no no no no no no no no no no no NNNNOOOO!!!!" Musujime has a complete mental breakdown causing a dimensional space warping every but Kuroko around her. Tables fling out the window, chairs hit the wall. Plates and pots are smashed against the ground. Some dimensional travel against each other breaking into pieces. "Ahhhh!!!" Musujime screams at disbelief.

The Arcade coin that Kuroko had during her investigations about the rumor of August 21 flings down to third rank level 5 nearby. "What?" Misaka said below looking up at the phenomenon that occurs above.

"Uhukk!" Saliva escapes Musujime's mouth as everything falls down, being free of the phenomenal that occurs by Move Point. "You!" A cold ruthless stare glaze down the wounded Kuroko. "I won't forgive you!!" Musujime ran up kicking Kuroko's wounded shoulder.

"Gyaa!" Kuroko cried out as Musujime continued to kick numerous times.

"You bitch! You stupid bitch!! How dare you break me?!! You're dead!! If only you hadn't come here you would have been fine!! And I wouldn't have to kill you, hell it's your fault not mine, bwahahahahaha!!" Musujime whipped out the gun once more but noticed there was a spoon screwed dimensionally into the gun. Musujime not sure if Kuroko cleverly did this or she unconsciously did this herself, this only made Musujime laugh even more throwing the gun at Kuroko's face. Musujime stares at a building thinking of a merciless attack and warps a wicked smile. "I'm disappointed Shirai-San something got in my way? Yeah right! I can still kill you as I'm making my escape." Musujime said, pulling out the briefcase and readjusting the handle fixing it. "My Move Point power limit is 4,520 Kilograms. I could bring this entire building down! That's perfect yes Gya Hahahaha!! I'll smash you into pieces a fitting death, just how you broke me. I should return the favor right?!"

"Tete," Kuroko's pitch giggle caught Musujime's attention, "So it seems that you still need that briefcase? Ugh!" Musujime runs up and kick Kuroko once more then strolls always with the briefcase.

"I have to..." Kuroko said, trying to gather up as much energy as she can. But to no avenue her body ignored her pleas. "This is bad. I let Musujime get away, and now I have to wait for my execution... Come on Shirai Kuroko!! Get up! There will be so many that I would have to beg forgiveness for this! ... I'm sorry Onee-Sama... I pray you do not make it to see this get as far away as you can... don't get caught up in this!" A phenomenal event occurred above Kuroko as she can see an entire building within the dimension. "4,520 kilograms. But suddenly a ring of light burst from below. To Kuroko's surprise, a Railgun of light strikes inside piercing everything in its path. "Onee-Sama?!"

"Kuroko!!" Misaka appears below crying out her friend's name. She quickly follows up with electromagnetism to form a bridge to Kuroko.

Kuroko falls down on the floor as her body dives down head first, "Onee-Sama! You can't be here, it's too dangerous..." But a certain boy runs on that bridge made by Misaka and follows up.

That hero catches Kuroko with the greatest of ease and as the phenomenal 4,520 kilograms sank down towards them. He stretched his right hand out towards the phenomenal and with one tap.

Crack! A sound effect ring. The delusion of Musujime's beliefs sank and vanished, restoring the original reality of how things should be shattering it into glass. The boy lands on the floor where Kuroko fought, holding her in his arms.

"You are?" Kuroko was puzzled by the boy's sudden appearance. "Why did you save me?"

"Huh?"

"One misstep and you would have died too... to be honest I thought our friendship gauge was in the negatives." Kuroko said now, realizing who the boy was.

"Umm... well if you ask me why, it's kinda silly. I kinda made a promise to someone after all."

"Promise?"

"Yeah... to some prick whose name I do not know. To protect Misaka Mikoto and the world around her... so what do you think? Did I manage to keep my promise?"

Kuroko looks at the boy, as Misaka runs up in relief to see her okay, and sheds tears.

"Yes you did... at least half of it... for that I'll take it from here... ape.
