Over Control…? Renko thought to herself while walking to her favourite book shop to get some reading material for her trip. Over control was her new nickname the principal gave her. Although it sounded weird, she could not protest or change it as it fitted her ability well. Renko let out a small sigh as she went to her favourite section of the book store.

Rumours huh…?

The principal also arranged a trip for the 3 level 5s to go on. It wasn't a vacation holiday but it was more like a training camp. Still, Renko didn't quite know all of them that well.

Oh boy this camp is gonna turn out worse than what I'd ever imagine. Renko muttered to herself. She bought the books and headed back to her room. On the other side of the road, she caught a glimpse of hazel brown hair and black goggles. She called out to the other girl.

Imouto! Renko shouted as loud as she could but was beaten by the noise coming from the cars which were on the road between them. She was slightly irritated and decided to use her ability to her advantage. She knelt down and tapped her shoes, by doing so, she was raised into the air. Renko swiftly floated to the girl who was still walking, completely oblivious to the fact that a flying girl was going to land in front of her.

WAH. Misaka exclaimed as Misaka did not notice Guardian. Misaka 10032 took a step back when she realized a shadow was forming on the ground. Renko landed like a feather on water.

Yea… I tried calling out to u but those stupid cars were too loud.

Renko held her hand up and one unlucky taxi behind her was lifted several inches off the ground and back down again. The passenger inside was one familiar spiky haired boy which yelled FUKOU DA in reflex to the taxi being lifted up.

So how have you been,Imouto?

Few months ago

Ah it's so relaxing… Renko was talking to herself on a building. Her peace was broken when she heard a scream…of a guy not a girl… she looked down from the building with an irritated look. That was when she saw a spiky haired boy holding a black kitten which was surrounded by hazel brown haired girls with black goggles. One of them was carrying a black trash bag which was shaped in a person's corpse.

Twins? No wait there's too many…

The spiky haired boy had a horrified look on his face. Renko then remembered about the rumours of The Railgun being cloned for an experiment. She flew back home, not wanting to mess with the higher up's experiments and getting caught in them would end up her own death. But Renko was curious, it was not her problem nor her fault but the it was the dark side of Academy city, it was somewhere she had been in and experienced it before… so she waited on top of buildings every day.

One lucky day she found Misaka 10031 walking around with a black violin bag slung around her shoulder, she followed her silently, making sure not to alert her newfound lead. Misaka 10031 walked into alleyways until she came across a white haired boy, Renko could not hear their conversation but it seemed that Misaka 10031 was taking out a gun from the violin bag and putting on her black goggles.

What the… I thought civilians could not keep unauthorised weaponry!

Then they began fighting. Renko paid more attention to the white haired boy's power. As Misaka 10031 was only using guns and electric shocks she already had guessed that she was an electrokinesis.

Some sort of shield? No… reflection? What the hell is this?!

Misaka 10031 was losing, the white haired boy was reflecting the bullets back to her. Renko then acted by instinct when the boy was going to put his finger into Misaka 10031's injury.

Oh no you don't! Renko shouted at the boy and jumped from the building, negating her fall by slowing gravity. The boy jumped backwards.

Hey… witnesses should be silenced right?

What the hell you talking about! Renko made square cubes with pointed edges by cutting them from the ground and flung them at the boy. The cubes just exploded on impact when they touched his "shield". Just as expected Renko thought.

Hey just so you know before you die… You can't kill me

Who cares!? That only made Renko more mad and dashed at the boy. He stood his ground with his bangs covering his eyes, expecting Renko to hit his shield straight on. Renko thought so too. Just before she made impact on the shield, she jumped up and formed "claws" from the pieces of the cubes that he destroyed. Even the boy looked surprised as he jumped out of the way, Renko then raised the ground beneath the boy so he would be boy merely flinched as he was being raised from the ground. As she made contact with the invisible shield, the claws exploded and now she was in grave trouble. Her weapon was destroyed and she was left defenceless. The boy touched Renko's stomach and she flew backwards, landing in a building. Renko felt sharp pain in her stomach.

Crap...did i just break a rib...Ok so I can't beat him so I just have to lead him away from her. Renko thought, it would be a better idea than fighting him here. She floated away, cursing insults at the boy, provoking him to follow her. It worked and Renko proceeded to lose the boy. When he had lost track of her, she returned to Misaka 10031 who had fainted. When she touched the girl, she accidentally logged into the MISAKA Network. But of course she didn't know, her mind was flooded with memories of Mikoto and the white haired boy.

Future,Now

Misaka is fine, the experiment has been cancelled, Misaka says as she wonders why Guardian is here.

MISAKA Network gave Renko the name of Guardian because she also, like Touma tried to help the project with similar thinkings.

Oh it's nothing I was buying books at a store nearby until I saw you.

Misaka hoped that Guardian have not been buying childish books and sleeping with a crocodile plushie every night, Misaka said while she hides her laughter

S-Shut up! Renko turned red.
