Before Story Notes.

As you may have read earlier dear reader this story is an Accelerator x Weiss but there will be other relationships as well that will be revealed in the story.

I massively buffed the RWBY characters in this story for very needed reasons to be revealed in the story as well as buffed aura, semblances and magic I also changed how magic works in this story as well no the Remnant magic doesn't follow To Aru rules I made my own rules for magic in this story, and yes Accelerator will eventually understand magic.

As for the relationship scenes there will be some intimate moments and mentions of after sex but there are no sex scenes in this story I was originally going to include lemon scenes but I ultimately decided against it doesn't mean that there won't be some spicy stuff to read at some parts though.

I changed some of the Remnant lore and gave the gods names for important reasons to the story. The Misaka Network is going to be very important as well.

This story will begin about halfway through RWBY volume 4 just a little before the Tyrian fight. Accelerator shows up in Remnant during NT 6 and it will go to probably A volume 12 or 13 while this story will be following some of the events of the RWBY volumes there will be a lot of stuff changed and eventually the story will take it's own direction and volume 9 will be very different then the cannon for a few important reasons and a certain relationship. Also A word of warning there will be RWBY and A Certain Magical Index New Testament spoilers. As well as some spoilers from some of the To Aru side stories.

As a final note I am not much of a writer so I used an A.I to help me write the story I will of course do my best to edit each chapter and fix mistakes before release.

Part 1.

The boy awoke to find him self in a frozen tundra, it looked like nothing for miles but snow and ice as he stood up he clicked a button on a choker on his neck this turned off what was known as ability mode.

The boy had white hair like snow and deep red eyes like blood he was very thin and his skin is pale white the boy was around sixteen years old but he is not just any boy, he is the strongest level 5 esper from a city known as Academy City a city of science those who knew him called him, Accelerator and now this boy was in a new place.

The last thing Accelerator remembered he was in a fight with Tetikou Kakine another sixteen year old boy he was the #2 strongest esper in Academy City his ability was known as Dark Matter it was a power even the great Accelerator could still not fully understand.

He remembered that Kakine had changed, his whole body had been made of Dark Matter and Accelerator had to admit if it wasn't for the #4 level 5 Meltdowner he would have probably been killed by Kakine, but thanks to her showing up when she did Accelerator was able to have enough time to figure out the properties of Kakine's strange dark matter vectors and reflect his attacks.

Accelerator's esper ability is vector manipulation with it Accelerator is capable of controlling anything that has the quantities of direction and magnitude,the moment he makes contact with it.

Any vector that touches him he can control it. Accelerator also has an insane intelligence he has the brain power of over one hundred super computers. So he is able to complete highly instance calculations in milliseconds this is why Accelerator is so focused on in Academy City.

Accelerator was once shot in his head when he used 100% of his power and brain to cure unit number 20001 known as Last Order of a virus, since he didn't have enough calculating power to fully reflect the bullet that was shot at him at the time, he was shot in the head.

Fortunately a certain frog faced doctor known as Heaven Canceler was able to save Accelerator and gave him a choker that allowed him to use his ability for 15 minutes at a time.

Accelerator was able to increase this time limit to 30 minutes by tinkering with it a bit, however at the moment Accelerator only had about 4 minutes of charge left, after his fight with that dark matter monster.

Tetikou Kakine didn't even look human anymore he was completely made of dark matter his body was completely white, the boy literally changed his entire biological structure, he was after Last Order and Frulan Kruten a gemstone esper that could never be killed or die in anyway. Accelerator was doing battle with him. Then that light enveloped Accelerator and that was the last thing he remembered.

The next thing Accelerator knew he was waking up in snow.

Accelerator looked around the tundra seeing nothing he used his cane he is required to carry to walk thanks to his injury, he can no longer walk correctly with out the cane when he is not in ability mode, he was walking through cold snow happy he still had his winter jacket on, normally Accelerator can manipulate his body temperature with his ability but with his choker off and his ability not active currently he needed the jacket in the cold.

As Accelerator walked by icy cliffs he heard a noice near by it sounded like a growl.

When Accelerator looked up at the top of the cliffs were strange looking creatures he had never seen before.

They were completely black they almost look like shadows and they looked like sabertooth tigers (Great did end up in the ice age.) Accelerator looked at the creatures, there was a pack of about 10 of them they jumped down from the cliffs and surrounded Accelerator.

Though he was not worried as he clicked on his choker activating his esper ability the creatures charged Accelerator ready to kill him and Accelerator did not move a muscle standing in one spot.

They charged and attacked Accelerator, but the moment the claws of the three of the creatures made contact with Accelerator's reflection, they were flung back in the opposite direction two of them died on impact.

What confused Accelerator about their death's was that instead of bleeding out like with a normal dead body their bodies turned into black dust and vanished into the wind (What the fuck?.)

Accelerator had never seen anything like this before the first thing that came to his mind was that this was a spell Accelerator has battled magic before, during WW3 once and all the members of Gremlin were magicians, they all had the power the AIM energy angel, Aiwass told him about.

A power with a different set of rules unlike anything he had ever seen before a power deemed magic.

It didn't make any since to him what ever these creatures were they were not scientific and he was not even sure if they were magic, another creature jumped at him and Accelerator manipulated the vectors of the wind and used the wind he sharpened the wind like razor blades and cut the creature to pieces, with Accelerator's power of vector manipulation he can control anything with direction and magnitude. This included force, velocity, mass, momentum, gravity, electricity, kinetic energy and many many more in other words over 95% of the universe's elements are under his full control.

Accelerator quickly delt with the creatures turned off his choker and continued walking after about 3 hours of walking he saw lights of a city in the distance, it was quite large and didn't look any City Accelerator had seen before, but what shocked Accelerator the most was that there was another city floating above the other one, he had never seen a floating city before.

This was when he really began to wonder where he ended up he figured he must of somehow traveled to the future the technology to make an entire city float was not something that existed in his time.

Accelerator eventually made it to the city after running in to more of those strange shadow like creatures and killing them all with his pistol this time to save ability mode, he made it to the city and saw a large gate with a guard at the front.

Part 2.

Accelerator looked at the gate guard, what was strange was the guard seem to be wearing some type of cosplay. The man had on dog ears for some reason, Accelerator did not see that as a very professional way to work.

He made his way up the ice road to the gate the man in uniform stopped him. "welcome to Mantle, where are you coming from young man," the man asked as he pulled out a phone the phone extended into a small tablet.

Accelerator had seen things like this back in Academy City but this was far more advancedthe ones in Academy City.

"I can't let you in unregistered, so let's start with your name," the man said.

"Accelerator," Accelerator replies to the man, Accelerator actually does not remember his birth given name because the experiments he went through back in Academy City,

"Where are you from," the man asked.

Accelerator was quite sure he was in the future and he was not to sure if Academy City even existed anymore, but he thought he would give it a shot anyway.

"Academy City," he says simply with a touch of bitterness.

The man was shocked while the man did not know every city name on the planet he was quite sure that there was no city with that name."Do you have some form of ID to confirm. I am sorry it's just I have never heard of A city with that name," the man said to Accelerator.

This confirmed what Accelerator thought, Academy City did not exist anymore (Fuck how the hell did I end up in the fucking future?) Accelerator thought as he handed over his Academy City Japanese ID to the man. The man took the ID and was once again confused as he stared at the ID, he could not understand it so he gave it back to Accelerator. "Yeah that's not gonna work either, that ID is in a language that has not been seen in centuries... it's not taught anymore so no one knows it... to tell you the truth I am surprised you have an ID in an old ancient Mistralian language," the man said.

This confirmed a lot for Accelerator one he knew for a fact he was in the future somehow and not only that he was centuries in the future, so for all Accelerator knew he could be in the 25th or maybe even the 30th century or further then that, two Academy City does not exist and for all he knew the continents were different so places like Japan or the United States or England or any places he knew probably don't exist anymore either, in other words he was royally fucked.

The man looked at Accelerator. "well I don't want you to get swallowed by a Grimm... tell you what I am going to make you an Atlas ID and just say your from Mistral, all I will need is your age," the man decides.

Accelerator just nodded his head in agreement.

Accelerator actually did not know his real age he had forgotten because of the experiments done too him by a man named Amata Kihara, but he knows he is anywhere from fifteen to eighteen years old for sure so he tells most people that he is sixteen years old.

"I'm sixteen," he says to the man.

The man then fills out some stuff on his phone then he snapped a quick pic of Accelerator and then Accelerator watched in amazement as a identification card was created from a thin light, to Accelerator it looked like some kind of nano technology he had seen it before in Academy City, but it was in prototype and this was so much more advanced.

"Okay this is an Atlas ID so make your way to Atlas," the man said.

"Atlas?" Accelerator asked.

"Its the floating city above Mantle," the man explained. "here take this too, it's a pass for an Airship too Atlas... look truth is your thin and from the look of that cane your crippled too and Mantle is not the safest place for a kid like you, so you will be safer in Atlas," the man said.

Accelerator took the pass and the card then the man was back to his phone.

Part 3.

Accelerator walked into the city, it was much more different then he thought it would be, it looked like a slum it was not really dirty but he can tell this were all the thugs and low lifes live, it even actually strangely looked to him like Gotham City from Batman comic books. The first place he headed to was a library he needed to learn what the world was like in the future.

Accelerator walked into the building and headed to the history section he found tons of books and sat down at a table and begun studying. About six and half hours later and he realized just how different the future was.

First Accelerator learned that the people in the future called earth Remnant. He learned that those strange creatures he fought a few hours ago are called Grimm and they seem to roam the world, destroying villages and attacking people.

Apparently they are attracted to negative emotions like anger or sadness and are considered Earth's/Remnant's biggest threat. Accelerator did not understand how these creatures that could sense human negative emotion came into existence in the first place, as there was nothing on that subject in the books, but he chalked it up to either some kinda science experiment gone wrong or someone's spell. He learned that half of the moon was destroyed somehow the books didn't specify. He learned that some kinda DNA splice happened at some point, because there are animal people who even have the traits of the animal they are spliced with.

Accelerator figured that at some point in the past scientific experimentation spliced people with animals and then later those people had offspring, eventually creating a whole new race called the Faunus. He also learned that faunus are discriminated against by some humans in Remnant, it actually kinda reminded him of the situation between high level espers and level 0 espers back in Academy City. He learned that this eventually led to a terrorist organization be created known as the White Fang, led by a Faunus woman named Sienna Khan which once again reminded him of Academy City with the group of level 0's called Skill-Out that went around terrorising espers and even sometimes pulling full out terrorist attacks on the city.

When, Accelerator searched for espers or people with abilities he found that apparently everyone in the future were able to manipulate the soul to create a shield called aura. He also learned that this aura could create a power that they call a semblance he was not sure how they worked, but from what Accelerator could gather semblances didn't require advanced calculations and they didn't use personal reality or quantum theory, they also don't admit an A.I.M Defusion Field like espers where he is from.

He also learned that almost everything in the future is powered by a power source they call dust. It could be used for powering ships, cars, homes, etc... but he also found out it could be used for combat as well and that it almost acts like magic. Accelerator found one thing to be odd and that is there is no space travel or space satellites, which actually started to make him doubt the future idea, well he knew he was in a future it just might be that he is in the future on a different Earth, meaning he would be in another universe making it even harder to get home, it was already bad enough that out of all the research Accelerator did he found nothing about the existence of time machines, or even time travel in general, neither was there anything on particle acceleration or multiversal travel theory or parallel universes or time-space manipulation or wormholes, not even einstein's theory of relativity seemed to exist.

Infact Accelerator found absolutely nothing on outer-space it was like the people here barely even knew that outer-space existed or they just had no way of reaching it.

Accelerator left the library thinking about what he found there was no way he was going to get back to the past or even to a different universe if that was even possible.

As, Accelerator walked out of the library it was now dark he looked and saw the partly destroyed moon and started to head to Atlas, as he was walking down an alley he get's cornered by a group of thugs, some were humans and some were Faunus. "Well well look here boys a crippled little shit out for a late walk," one of the thugs says as the group corner him from all sides.

Accelerator's walk is halted as the thugs move in on him and a few of them surround him in a ring. Accelerator looks at the thugs with a bored look on his face and says. "Wow you guys are out robbing innocents, who most likely barley have enough money to live? You are really fucking pathetic villains," Accelerator says as he then reaches up to his choker and clicking the button activating his ability he can immediately feel all the vectors around him. "You know what were gonna let that slide, since your obviously a little punk kid so hand over your lien and we wont fuck you up kid," one of the thugs says as he reaches for his shotgun.

Accelerator learned back in the library that lien is the currency for the future or possibly this Earth's future he still wasn't completely sure but it didn't matter, for one Accelerator did not have any lien, he would have to get his hands on it soon though. He bet that these thugs have been stealing lien from a lot of people, so he can just take it from them after he dealt with them.

one of the thugs points his shotgun at Accelerator.

"You try anything and you will die here kid," the thug says.

At this comment Accelerator can no longer hold it in and he begins laughing like a mad man. "Ha ha ha ha ha ha ha ha ha ha! That's rich! you really think you punk ass villains are a match for a world class villain like me!? Ha ha ha ha ha ha ha ha ha ha!"

As the thugs react with shock on their faces at the sight of Accelerator laughing and acting like he is having fun.

"See how funny this is you little bitch," a thug says then aims his shotgun at the head of the laughing and mocking Accelerator.

He fires a shot and it gets reflected after coming in contact with Accelerator's vector shield, the bullets reverse direction and hit the thug that fired them.

"SHI-!!!" the thug yells as he collapses to the ground.

At this point everyone is just staring at the albino boy in shock another pulls out a handgun and fires two bulletsat Accelerator and when they come into contact with Accelerator, he manipulates their vectors increasing there speed to the speed of a railgun while manipulating the electricity running through the air around them. Just like the #3 Mikoto Misaka, the Railgun in Academy City when Accelerator fought her he got the idea to use a railgun from time to time.

The impact of bullets increased to Mikoto's railgun speed went through the thugs aura and his body even exploded into pieces, blood and body parts flew everywhere and landed on everything and everyone except Accelerator, who reflected the blood and body parts away from his body Accelerator then looked at all the other thugs with a sadistic crazed look as he was enjoying this.

"Well look at you all now!"

"HA HA HA HA HA!!!"

At this point all thugs are staring at Accelerator with terrified faces, they were facing a monster scarier then a Grimm.

"HA HA HA HA HA!!! you all thought you could take on a man who has used every dirty tactic and every dirty trick in the book right!?"

"HA HA HA! You all are going to suffer you little shits!" with that Accelerator moves so quick he seemingly teleports, he appears in front of one of the thugs and places his hand on the mans chest. Accelerator manipulated the vectors of force and velocityaround his hand and he sends the thug flying into a nearby wall.

The impact breaks the thugs aura and and leaves a large crack in the wall, while the remaining thugs drop there guns and start running away with fear in there eyes.

"Where do think your going you little shitbags!"

Accelerator manipulates the vectors of his momentum and moves at immeasurable speeds and appears next to one of the three remaining thugs. Accelerator then manipulates the vectors of the air sending a small tornado in the direction of the other two thugs while he grabs the thug next to him and manipulates the man's bio electricity. The mans screams as blood leaks from nose, eyes and earsbefore he drops to the ground dead.

The tornado Accelerator sent out before had caught one of the two remaining thugs and ripped him apart the last thug had fallen to the ground and backed into wall in fear Accelerator noticed the man had peed his pants.

Accelerator slowly walked over to the man with a face of no emotion or feeling he looked bored Accelerator then pulled out his pistol and pointed it at him. "Please don't, please don't kill me I'm sorry please, I'm sorry I will never attack anyone or steal from anyone again please," the man had tears streaming down his cheeks.

"You truly are pathetic, you call yourself a villain, but then you involve innocent people you attack people who have nothing to do with darkness, hurt and kill innocent people, those who try to live there day to day lives in peace, who have normal jobs and couldn't lift a fucking gun to someones head if they wanted to, you piece of shit a true villain does not involve innocent people, true villains stay in the darkness they don't hurt people who are not part of that world, they stay where they belong and let those who want to live peacefully to live peacefully, true villains deal with the darkness and they kill so the heroes don't have to, you are a disgrace to villains," points his gun at the mans head. "This what true world class villain looks like you mother fucker!" with that Accelerator shoots the man in the head.

(This is what it means to walk in the darkness) Accelerator thought to himself as he walks away leaving the carnage he just caused behind him as made his way to the Airship.

When he gets to the station, Accelerator shows the woman maning the gate his pass and she let's him on with out a word and short ride later Accelerator finally arrived in Atlas.
