We all know what happened over one hundred years ago in the Seireitei, when the Aizen began his experiments on innocent people, soul reapers and captains. But what would have happened if Aizen had unintentionally dragged another innocent and unsuspecting soul into his plans and took them a bit further than first intended? How would the plot change just from one little girl's existence and spur of the moment involvement?

OC as main character, follows original storyline on most aspects but with tons of changes, Rating M for some bad language, violence and Minor suggestive themes (Maybe later on in the story), Using terms from English version. Spiritual pressure instead of Reiatsu and etc.

No lemons!

This is my first fanfiction so sorry if there's many mistakes or it's bad or boring etc, I've already been told countless times how crappy my writing by teachers but i somehow still got an A and B in my English exams o.0

I like writing this, it's like an escape for me so I'll carry on for my own enjoyment if no one likes it :)

Keep in mind that these events are parallel to the real events of the anime/manga, try and match them up and relate them with the dates that I give. :)

I do not own bleach, Tite Kubo does. Though I take credit for my OC's and my ideas, Enjoy and Review ^^

Bold + Italic = Thoughts.

It was that awkward moment again, the one that happens at least once in every teenager's school life. That moment when you are so far away in your own little world and are so rudely bought back to reality by a teacher. Inconsiderate fools.

This was happening quite a lot recently and she was getting a bit of a rebel reputation for it, but not like she cared. Reputations meant nothing to her. She had been sitting next to the window about half way along the classroom, with her pencil hanging in her mouth dumbly, hand on her chin, her unblinking gaze fixed on across the academy grounds, completely oblivious to the world around her. That is until a heavy book slammed down on her desk and almost made her fall off her chair in fright.

"Murasaki! Will you please pay attention, I'm sick of you not listening and having to repeat myself" their history teacher bellowed down at her. Her heart still pounding violently against her ribs, she stared up at the teacher paused for a moment and then pretended to faint, slamming her head down on the desk with her tongue lolling out. Of course the rest of the class found this highly amusing but the teacher wasn't the least bit impressed.

She looked up after a few moments, her eyes forming that signature glare." And you think scaring the living daylights out of me is gonna help?" she retaliated, looking up at her livid teacher.

"Maybe it will scare some sense into you!"

She sighed deeply and rolled her eyes, knowing this argument could last for the rest of the period, but she couldn't be bothered to continue it today. "Yeah all right all right, can you just repeat the question please?"

The teacher raised an eyebrow. This girl was usually argumentative, Was this a sudden improvement on her bad attitude? The teacher decided to not question the change and repeated the question anyway. "What is the most powerful flame type Zanpakuto known to the Soul society to this day?"

"What the-" the girl began, about to question the question. The teacher winced, as though being stabbed by the words, and changed his mind the instant the girl opened her mouth to answer. She's still argumentative, I guess that's punishment for getting my hopes up. "Why are you asking such obvious questions... a five-year old would kno-" she cut off when noticing his expression and decided to just answer and get the teacher off her back. "Never mind. The answer is Ryujin Jakka, owned by Yamamoto Genryuusei, the founder of the academy and leader of the 13 court guard squads." she recited, knowing this simple information off by heart, but she might as well redeem herself by giving a good answer.

"Good. That wasn't difficult, was it?" the teacher asked sarcastically, walking away back to the front of the class, reading aloud from his text-book as he went.

She sighed again and took to doodling in the margins or her text-book for the rest of her lesson until the bell rang for dinnertime. She caught a few sideways glances from some of her class mates staring at her or giggling occasionally, shooting back her famous signature death glares which silenced each one of them.

Once the bell rang she was one of the first people to leave the room, practically leaping over tables towards the door. A short way down the corridor one of her friends, or rather rivals as she considered him, caught up with her. A Tall boy with scarlet red hair up in a spiky pony tail.

"Heeyy!" he called for her and she slowed down not turning to look at him. She knew what was coming. "How the hell do you manage it? How do you always cause more trouble than everyone else huh?" he snickered putting a hand on her shoulder.

"Shut it Renji, I don't do it intentionally you know, it just-"

"Just happens?" he finished her sentence for her. "Maaaann that's talent at its finest right there, too awesome." he laughed smacking her roughly on the shoulder.

"Har Har, very funny." she replied rolling her eyes again as they walked, still not looking at the boy. For one: he was at least two foot taller than her, and she didn't enjoy craning her neck to look at him, which was the source of many of their play fights and disagreements, and for two: she just wasn't in the mood today.

There was a call from behind them as some of Renji's guy friends called for him to join them. She finally turned to look at him.

"Uh, right, be right there guys. What you gonna do for dinner?" he asked her. She shrugged.

"I think I'll go chill under my tree in the grounds again."

"So now you own a tree?"

"Shut it. Don't even go there" she winced in annoyance.

"Alright all right" he turned away from her and stopping, pulling a thinking face for a second. It seemed as though he was thinking of saying something else and seemed to change his mind. "I'll see ya in next lesson then?"

"Yeah. See ya next lesson" she gave him a small, slightly forced smiled and carried on to her destination.

She soon came to rest under the shade of a large Sakura tree in the grounds of the Academy, her favourite spot for various reasons. She set her bag down beside her and lay down with her arms behind her head, staring at the sky and drifting into another daydream almost instantly. This time she thought not of her wildest dreams, fantasies and weird stuff, but of the past, her most reliable remaining memories.

The pendulum ticks back to 110 years into the past, where this all began.

It was a cool spring night in the Seireitei where Yamamoto Genryuusei sat in this office, a mountainous pile of paperwork perched on the desk in front of him, tottering tediously from side to side as though the faintest gust would send it toppling across the room.

Yamamoto did not like nor dislike reading through the reports of his thirteen squad captains, but when his dearest Lieutenant Sasakibe wandered into his office carrying a pile of agonising boredom, such as this monstrosity, his heart sank.

These papers are extremely high priority, the sooner I read them the better the old man urged himself. He leaned forwards in his chair ever so slightly and slowly reached a wrinkled hand towards the top few papers. "No... sudden... movements..." he mumbled as if the vibration of his words in the air may send the pile flying.

As if karma was out to spite him, the towering wooden doors to his office came crashing open and young man with short and messy mousey blonde hair wearing a Captain's Haori came to kneel in front of Yamamoto's desk, completely oblivious to the rain of paper falling from the ceiling.

Yamamoto held his face in his palm, despairing. Why did I hire this buffoon? His stupidity never ceases to amaze me. It will take forever and a day to reassemble these papers in the correct order he thought, again regretting hiring the man all those years ago due to his clumsiness.

"Captain commander-" the man began to pant, out of breath and red in the face from running. Yamamoto cut him off before he could continue.

"Were you born in a barn, Captain Urahara?" he asked sarcastically.

"N-no sir... I was-"

"Then learn to knock before entering and close the door behind you. And collect these documents off my floor this instant." He snapped.

"My apologies Captain, but I've come to report that the Department for Research and Development have detected a massive amount of Spiritual Pressure approaching the World of the Living, It's like that of a hollow's but multiple one hundredfold!"

This caught Yamamoto's attention and he stood up, momentarily ignoring the sea of paper. "You are sure of this, Urahara?"

"One hundred percent Sir, the spiritual pressure readings are off the scales"

"And the location?"

"Karakura Town, in the West of Tokyo, Japan."

Yamamoto lifted one fluffy eyebrow in surprise. A small black butterfly appeared from thin air and floated down to rest on Yamamoto's index finger. He spoke to it.

Every Soul reaper in the Seireitei did as instructed and stopped their current action to listen to the wizened voice emitting from the air around them, as though through a giant invisible megaphone.

"Attention. An immense spiritual pressure is approaching the human world. Squads 2, 5 and 9 are to be dispatched to Karakura Town to access and handle the situation. All other squads, with no exceptions, are to remain on standby and patrol the Seireitei. Any suspicious activity must be reported and dealt with immediately. I will not allow these attacks and disappearances to continue."

Once finished, the Hell Butterfly fluttered off his finger and out of the nearest window.

"Captain Urahara, go back to Squad 12 labs, access the situation and keep us updated, any changes must be reported"

"Sir, I would like to join Captain Yoruichi of squad 2, they are lacking squad members due to the recent attacks, they need back up... I will have my Lieutenant and seated members taking care of Squad 12's duties back at the labs, they are fully capable of the job"

Yamamoto paused to think for a moment. "...Very well. Any negligence or mistakes made will be on your head, Urahara. I'm counting on you"

The young man blushed a violent shade of plum, bowed and scrambled from the room.

Yamamoto strolled across his office to stare out across the Seireitei. It was half way through the night and for miles hundreds of tiny lights could be seen igniting, voices could be heard in the rooms and streets below. What on earth could be happening now? As if the recent attacks on residents of the Rukongai weren't enough, now the World of the Living too?

But Yamamoto would not let his guard down. An attack in the middle of the night was surely done to throw them off guard, unless this anomaly was a coincidence. No, it couldn't be a coincidence, the timing was too perfect he thought. Even if this had nothing to do with the Soul Society's recent troubles he wasn't going to take any chances.

He took a deep breath and resumed his seat behind his desk, staring at the waves of paperwork as if to make them clean up and reorganise themselves.

A while later

A group had congregated at the main senkaimon of the Seireitei, waiting to be dispatched to the Living World. Captain Urahara rushed towards the impatient, groggy looking bunch. "Sorry I'm so late, had to lay out firm instructions to my squad" he explained, waving a hand apologetically.

"What is this about Urahara?" A man with a pointed face and long straight blonde hair, also wearing a white haori, asked sounding annoyed and yawning boredly. "You disturbed my beauty sleep."

"You know as much as I do, Captain Hirako. Let's head out and maybe we can answer your question" he said, gesturing towards the large gate as it opened to reveal a shining white light.

They entered the light without hesitation. The small group of ten people, four captains and three lieutenants and three third seats rushed through the precipice world. The walls which usually moved and undulated like the stomach of some sort of creature stayed still as they passed, nonetheless they remained in a closely knit group.

Once the light at the end of the tunnel appeared, they jumped out of it, the wooden doors sliding shut behind them. They had entered a place that seemed to be the outskirts of a town. A wide river ran below them, with pedestrian paths and grass verges leading up to a football pitch on one side of the river. On the opposite side of the river was the edge of either a very large town or small city, with residential areas close to them and larger buildings in the distance.

The group of Soul Reapers stood and observed the scene for a moment. Another man with short white hair wearing a captain's Haori spoke first, evidently annoyed. "Well, Urahara? I don't sense any strange spiritual pressures. So, were you wrong or were you pulling some stupid prank on us?"

"On the contrary, Captain Muguruma" Urahara's face was completely blank of expression as he pointed to the sky. A dark cloud was forming far above the town, like a monstrous storm. The Soul Reapers turned to the direction he was pointing and looked on in horror.

"What is that thing?" A girl with short midnight blue hair asked her captain in fear.

The sky suddenly began to quake, a rip appeared with began to open like a mouth being unzipped. "A Garganta, Sui Feng." Yoruichi answered, stepping forward in front of her student. "The exit, or entrance, from Hueco Mundo into the World of the Living."

The lieutenants took a step back as their superiors clutched their Zanpakuto's and prepared to fight. Out of the Garganta stepped a monstrously tall black figure with a white pointed mask-like face, followed by what looked like millions of smaller hollows.

Out of the entire group, only one person wasn't bothered by these monsters. A young man with short curly brown hair stood behind Captain Hirako, the corner of his mouth twitching into what could have been the beginnings of a smile for a split second.

"I'll take care of these guys" Captain Mugurama shouted, taking out his sword "Blow it away, Tachikaze" currents of air began spiral around him and the sword and it turned into a small knife.

"Wait Kensei-" Hirako took a step forward but Kensei shot off in the direction of the hollows. "What a fool, he can't take this many hollows and Menos Grande alone" he sighed unsheathing his own Zanpakuto and following after Kensei, "Let's go Sosuke." The brown-haired man nodded and followed Hirako.

Urahara and the other captains and lieutenants watched as more and more hollows escaped from the Garganta.

"We must stop this, we cannot allow these hollows to escape into the City, it will be chaos to destroy them all. Yoruichi, Sui Feng, can you two help me catch those hollows that pass us?" the two nodded. "Good, then i want the rest of you to help Captain Hirako and Captain Muguruma destroy the hollows at the Garganta and close it, understood?" he said, turning to the remaining Soul Reapers who all agreed and shot off to help.

Kensei was already up at the Garganta, slashing through the Menos with ease, Hirako helping him and catching a few of the hollows that tried to pass them too. One of the Menos drew back and opened its mouth, forming a sphere of red energy. "Kensei! look out!" a girl with green hair and a pink scarf shouted. Knowing he wouldn't move in time she dived down with both her legs straight. "Mashiiiiroooo DROP KICK!" and hit in square in the back, sending him flying.

Kensei spluttered and regained his balance just as a beam of red light ripped past them, leaving a sort of sonic boom in its wake. He rubbed his back, for once he was thankful of Mashiro's amazing athletic ability. "Thanks a lot, it hurt but I'd rather have back pain than be dead" she giggled and back flipped out of the way of a bat-like hollow, upper cutting in the chin it with her foot.

The streams of hollows leaving the Garganta seemed endless, and the Soul Reapers were getting tired, fast. "Third seats! Do not let the hollows pass by! Do not allow them into the city! Kensei, at this rate we'll be needing back up" Hirako said, moving back to back with Kensei to catch his breath after slicing a Menos in half.

"Your right... there's... too many... of them" he panted too.

In a dark alley way in the suburbs of West Karakura, a spirit girl hid behind a row of trash cans sobbing but trying not to make any noise.

What's going on? What are hell are those things? She thought frantically. She felt that unexplainable feeling that forcefully washed over her when one of those creatures were near and shrank as far into the shadow as she could, though her new pearly white body didn't help the situation in the slightest, she felt more noticeable like this.

It came down the alley way, in the form of a monstrous Komodo dragon lizard with a skull-like white mask. It's snake-like forked tongue rattled as it sniffed along the alley way, trying to find its target. The spirit girl sucked in her gut, hoping foolishly that it would help her be less noticeable, but the hollow stopped dead right next to her. It gave off a putrid stench and a howling cry then turned it's head to the her.

She instantly rolled sideways, not giving it another chance to try to eat her and ran as fast her legs would carry her down the alley, the little chain attached to her chest clanging from side to side. The monster scurried after her, roaring again and swiping at her. She took a sharp left turn down another alley trying to throw it off and confuse it but instead it just ploughed through a wall and around the corner like the wall had been made of jelly.

She gasped in shock and carried on running, transparent tears torrenting down her face more than ever. This is the end; I can't keep this up for much longer. She turned her head to the right and saw the main road in front of the Karasu river. She didn't stop but carried on running down the road, hoping against hope that she would find someone who could help her. Suddenly the hollow that had been chasing her launched over her head and landed in front of her as though it had fallen from the sky. She grinded to a halt and span around to run the other way, but another hollow in the form of an eagle landed in front of her that side too.

She was cornered. It was really the end. I'm sorry... I never got chance to say sorry to you... Forgive me... she thought. She crumpled to her knees, holding her head in her hands waiting to be slaughtered.

Overhead Urahara, Yoruichi and Sui Feng were running across the rooftop's, search for hollows and defeating any they came into contact with. Sui Feng took the back of the group, she slashed through a hollow that had landed behind her mercilessly and spotted two more on the road below. "Captain, down there!" She yelled, making Urahara and Yoruichi stop and change direction, pointing over to the two hollows cornering a spirit. They shot down to the floor with lightning speed flash steps and came to stop before the hollows.

Urahara held his Zanpukto above his head and forcefully stopped the clawed hand that had swooped down to the spirit girl, Sui Feng did the same with the other hollow but completely sliced off its talon. It gave a huge painful screech and the spirit girl looked up.

"I'm... I'm alive!" she cheered.

"Well, not exactl-" Urahara began to chuckle.

"Kisuke!" Sui Feng yelled "Now is not the time for that!"

"Right, Yoruichi!" he called. The girl stared around at them, completely confused by what was now happening. Yoruichi appeared next to the girl startling her more than she already was. She smiled reassuringly and held a hand out to the spirit, helping her up and moving her away from the fray.

"What are those things?" she asked as she and Yoruichi stopped at the corner of a building a few blocks away. She looked around to see the girl and man who had saved her following close behind with more of those... things.

"There's no time to explain, but let's say you'd be in trouble if we didn't find you when we did" Yoruichi smiled. Urahara dived round the corner to stand next to them as Sui Feng distracted the approaching hollows.

"Now, little girl-" he began but was cut off.

"I'm not little, I'll have you know I'm sixteen years old!"

"Yeah yeah, ok, now kid, sorry to spring this on you, but it's dangerous here and you need to move on-" Urahara said holding the hilt of his sword backwards. The end of it glowed bright blue and he moved it towards her forehead.

"Whoaa, don't come near me with that thing" she said leaning side ways to avoid it.

"For god sake Kisuke-" Sui Feng cursed, her tone harsh, getting impatient as she continued to fend off more hollows.

"I know, I know, Look I'm going to help you move on to the next life by giving you a Soul Burial, you can rest in peace"

Her eyes widened in horror "No! Please! I'm not ready to go yet! I need to say sorry-" she stopped with a gasp as a huge beam of red light ripped across the sky above them, causing an explosion in the distance.

"I don't have time for this, it's too dangerous here right now, if it was any other time I would help, but I can't. Good luck kid, you'll be needing it." And without waiting for her to answer he planted the hilt of his Zanpakuto on her forehead and watched her vaporise into tiny wisps of blue smoke and butterflies. He sighed and sheathed his Zanpakuto once she had disappeared.

"Good grief, I'd have to strangle that kid if I knew her, so annoying" Sui Feng protested. A hollow that had been charging towards them suddenly stopped dead and turned in the opposite direction. She frowned, not understanding why it had suddenly changed course, but she still didn't sheath her Zanpakuto "That's... odd"

"I don't know Sui Feng, if I knew her I think I'd like her, I liked her attitude. That girl had guts." Yoruichi contradicted, ignoring the retreating hollow.

"Y-yes ma'am but-" she began to stutter, giving in to her master as always but Urahara interrupted.

"The hollows seem to be attracted to these spirits, so if we want to get rid of the stray hollows all we have to do is find spirits and the hollows will come to us. We've got a lot of work to do so let's get moving" The women nodded their agreement and they flash stepped away from their spot.

One by one, they found lost spirits. For a while they would walk around with the spirit, using them as bait to attract all the hollows in their current area in large groups, helping to defeat large amounts of hollows at once. Once they stopped pursuing the spirit they performed Soul Burial's on them and helped them move on to the Soul Society. The city was so vast that it took quite a while with this method, but it was effective in the long run.

Eventually less and less hollow came out of the Garganta making it easy for Kensei's team to eradicate them before they made it to the city, leaving it to Urahara's team to get rid of the ones skulking around Karakura.

It took a huge effort to force the Garganta to close, but they did it eventually. All ten of them scoured the city for stray spirits and hollows, just to clean up after themselves and then gathered at a spot near where they had entered by the river.

"A job well done I'd say." Hirako smirked wiping a scratch that was dripping of blood on his cheek. "Put your face straight Sosuke, you did well. Stop being such a grouch." he added, noticing the expression on his Lieutenant's face.

"Yes, Captain." he replied simply. "Lack of sleep, Sir."

"Ok, time to go back home. I'll report to the commander, not sure if he wants us to stay on alert or go back to bed though" Urahara laughed at Sosuke and Mashiro's tired expressions. He opened up a Senkaimon and entered, yawning as the others followed suit the wooden doors sliding shut and vanishing behind them.

And there is chapter one ^^

I hope you liked it, so please leave a review with suggestions, especially if you find spelling and grammar mistakes. I have a really bad habit of repeating words and using random capital letters subconsciously.

As the story is based on time, I'll probably be using quiet a lot of time skips, and moving forward and backward in time like i did here. You'll get a proper introduction to our Main character/OC in the next chapter.

Also I decided to make the Academy more like a normal school, and not how it is shown in the anime with large classrooms. I'm making the classrooms normal size
