Rukia Kuchiki was wondering how her first mission to the real world as member of Squad Thirteen would go. She knew that she was only able to get into the Thirteen Court Squad because of her newly adopted older brother Byakuya and there were those that did not like her because of this.

Though that was not much of problem. When she first arrived, thanks to lieutenant Kaien, she managed to make the transition from academy student to member of the Thirteen Court Squad rather easily.

"So is there anything I could do to help out?" Rukia asked. She really did not know what exactly she was supposed to do other then help her group searching the area to find out why hollows were becoming more active in this area.

"Help out this simple search and nothing more we probably will not even see any action" one of her squad members told her.

"Okay," Rukia responded and simply went along with the others in checking the search area.

However, this time the search was anything but routine; somehow Rukia's group was attacked by strange hollows that drew them into the area between Hueco Mundo and the Soul Society. They had managed to dispatch the hollows with some effort and minor injuries even though they have never seen that type of hollow before.

Yet this was only the start of their problems when cracks in the 'sky' itself formed and out of them came hollows that most of them had only seen in books. A gillan class Hollow or as they knew a Mendos Grande appear before them and with a simple swipe of their huge hand managed to take half the members of search party and Rukia barely managed to escape sharing their fate.

The remaining members and Rukia tried to flee but it was no use. Mendos Grande was not going to allow any of them to escape alive and blasted the remaining shingami with a cero which wiped out every one of them but Rukia who at the last minute was pushed far enough away that she would survive the blast but was still gravely injured from the attack. The gillan, rather then finishing her off, just got up and ran when something seem to have scare it off. Thus Rukia was left lying there, badly injured by the cero blast.

With whatever energy she had left within her body, the Kuchiki girl forced herself stand despite her injuries and, using her zanpakuto as crutch to support her weight, Rukia began staggering her way back toward Soul Society. After walking for about twenty minutes, she collapsed to the ground.

'What strong spiritual pressure!' Rukia thought. In her current state, her legs just gave out and were almost unable to move, and she was on the verge of losing consciousness. Though before this could happen, Rukia managed to turn herself over and look up to see the captain of the Squad Five Sosuke Aizen walking towards her from the direction of Hueco Mundo with what appears to be a green hair little girl over slung over his shoulder, yet she could see that she was there was something off about her. There appeared to be a cracked hollow mask on her head.

Though the thing that Rukia found strange and somewhat unnerving was this spiritual pressure which had completely paralyzed her and was causing her to lose consciousness. This person walking towards her was none other the Captian of Squad Five Sosuke Aizen. Rukia had overheard about how he managed to save Renji and the other that time they were ambushing by hollows in the land of the living and how kind and gentle heart he was from various people around the Seireitei. However at this moment what she was seeing was nothing like she had previous heard in regards to the Squad Five Captain. Rather then the kind face what she saw as she was on the verge of losing consciousness was menacing eyes glaring down at her with cold indifferent expression upon his face. Before she could think of anything else, she lost consciousness, leaving herself at the mercy of the drastically different Aizen. The fifth Squad Captain then picked the injured Kuchiki, throwing her other his other shoulder, then walking off with both them, but not towards Seireitei.

Twenty minutes later in lab with the 75th East Rukongai districts, both Ruika and the girl were floating a tank with Aizen looking over them.

'This should be interesting,' Aizen thought. He had mastered everything there was for a shinigami to master. Swordsmanship, hand-to-hand combat, footwork, and kido all four forms of shinigami combat had been mastered by him years ago. He desired to get stronger and the only way he saw to do that was to gain Hollow powers. However the problem with that was how to go about gaining the power of Hollows without being consumed by them. Fifty years ago, this led to him to seek out hollowification as a possible way of achieving his goal, though the results he found were less then his expectations. All his attempts then were failures except for eight shinigamis that Kiksuke Urahara managed to save, using something he apparently called the Hogyoku which seem to help stable the unstable half hollow shinigamis.

This got Aizen's attention because if there was a boundary that separated shinigamis and hollows, then maybe at one time they were all one species that was split into the two that existed today.

This idea would make sense. Otherwise, why was it possible for one to gain the abilities of the other if they at some point did not have a similar ancestor.

So with this in mind, the Squad Five Captain began experimenting with a number of shinigami and Hollow to see if he could successfully create a perfect fusion of both a hollow and shinigami rather then one then simply having the power of each other. Such was the case with arrancar and vizard(as he heard the eight shinigami were now calling themselves). He wanted to see if he created a being that was not merely using the power of the other but truly had the power of both a shinigami and hollow, which lead to the creation of new race in the spirit beings he called vizancar. Though the problem so far was that all of them so far were either completely failures or only partial successes. He had been unable to produce the result he wanted thus was currently searching into the location of the Hogyoku or something else that might be of more use to his goal; but for now, he would continue making vizancars since despite being none being the perfect success he wanted, there was still a lot to learn from studying them and they could make excellent foot soldiers for him.

'However, it looks like I lucked out today. Who would have guessed this girl would be an arrancar girl who would be espada and from that number on her back, she appears to be a rather strong one,' he thought. Though why she was in the middle of desert and even this form was a mystery to the Squad Five captain, but one he really did not care to solve. This was the strongest hollow he found for his experiment so far.

After examining her, Aizen discovered that espada differ from other arrancar since not only do they gain shinigami powers by the removal of their mask but apparently they gain something similar to a soul chain and soul orb. As Ruika and the girl arrancar float in the tank, one could notice that slowly the two of them seem to be dissolving and reforming into one being. With this experiment, Aizen wondered what wonder would happen if he cut Rukia's and espada girl's soul chain and orbs in half then mix and match them while within a tank he created specially for fusing shinigami and hollows together without all that noise that plagued his earlier experiments.

While Rukia and the green hair espada were being fused together, Aizen turned his attention on how to cover his tracks. Normally he would just use the special ability of his zanpakuto's Shikai to fake the deaths of those he experiment on. However with Rukia, he did not want to take that chance because he mostly used cadets to mid level shinagimi that were not from any noble family until now. Thus no one really cared to look to deeper in the matter since they were seen as simply killed and that was the end of story. With Rukia being a noble though, it was different. He was sure this might lead someone to finding out that something was wrong with the fake body even through they were under his Shikai's power. So he then took the other half of Rukia's Soul chain and orb over to gigai he made that looks just like Rukia. This however was not a normal gigai, but a spirit gigai he had made based off the untraceable Gigai that Central 46 used for the cover story when Kisuke Urahara was to be exiled. Unlike those gigai which drained a shinigami of their powers reverted them to human form. This one was made so that over time it actually became the shinagimi it was replacing, minus the memories though. He was sure that by giving the gigai the other half of Rukia's soul chain and orb, it should gain all, if not most, of her ability and memories. He discovered that soul chains and orbs can be restored as long as it was not destroyed completely. Simply cutting it in half left the other half to grow back given time. Once he was finished with the gigai he planned on using to replace Rukia with, he then made it so that no one, not even the gigai, would know that they were not the original Rukia but simple a replica he created. As for the other half of the espada girl's Soul Chain and orb, Aizen would study it to learn more about espadas and possible something towards his goal. Thus the original Ruika and espada girl were left in the tank to merge with one another both sharing half a soul chain and orb.

While Aizen left to put his plan into action, the report that he gave was that Rukia's unit was attacked by Gillian and he barely managed to save Rukia from being killed. The spirit gigai copy was done up to mirror most of the injuries that the real Rukia sustained to keep the appearance to match with his story.

While Azien was confident in his ability and that of his Shikai, there was something he overlooked. That being the fact that neither one was perfect and there were ways of getting around the hypnotic effect it produced other then just being blind. It was to this end that one of vizancar he thought was dead came to the lab seeking information that would help them in defeating him. Other had tried and all of them were now either dead or kept somewhere as his personal guinea pigs

The vizancars, who looked in their twenties, had something on that looked somewhat similar to the standard shinigami uniform yet there were a few differences. Instead of two kimonos, they only had a dull white kosode (short-sleeved under-kimono) on. Also the pants were ripped, stopping around the ankles and they were bare foot with signs of not having worn anything in years. Their hair was maroon color while their eyes were two different colors. The right was maroon like their hair but the left was scarlet and the white of their eyes were same dull white as their kosode.

"Good, it seems that he is not here, but I had better make this quick. There is no telling when he might get back," the maroon vizancar said to himself enter the lab.

"Well, this is interesting it seems that Azien has changed his method in his twisted experiments," the maroon hair young man said as he looked over at the new being that was created through the merging of Ruika and the green hair espada.

The vizancar that was floating in the tank looked like a twelve year old girl wearing a standard shinigami uniform but it was tattered at the bottom and the sleeves. She had dark green hair that stopped about half down her neck (the hairstyle is exactly was like Ruika's in looks but is somewhat curly like Nel's). On her face right under her eyes was red tattoo that stretch for one eye to the other. Though what he found rather interesting was that right between her eyes was large vertical scar, but it was not that noticeable because the strain on hair that hung over it. The only reason he could probably see it clearly now was because she was floating in a tank of liquid. Another interesting thing was that on her head was damage hollow mask in the form cartoonish skull. Her eyes could not be seen because she was currently unconscious.

Not want to leave her at the hands of Azien, he broke the glass and took the girl with him since Aizen would probably kill her if she did not met his expectations right away like he had tried with him or use her as guinea pig for further experiments.

When Azien returned after planting the Ruika gigai to see the result of his latest experiment about three later, he was pissed not only find that they were gone but the tank was broken. He then began wonder just who could have stolen her from the tank or if somehow the vizancar girl woke up and ran away on her own. The latter was unlikely. The tank was made to keep them unconscious because the cursing and threatening got annoying after while. Leaving only the option being that someone came in here while he was gone and took her. The problem was just how did they, and who since he was not close enough to his goal yet to desert Soul Society yet.

Meanwhile in the alley somewhere around 80th East Rukongai districts

"What the hell were you thinking, Toka?" a dog woman around twenty years old yells. She bashed Toka (the maroon hair vizancar) in the head with her right arm.

She too wore a shinigami outfit similar to his except her left arm sleeve was cut off at the shoulder. In place of normal ears she had floppy dog ears on the sides of her head. Her dog-like eyes were also two different colors like Toka's. Her right eye was blue and over the left red eye was a scar that ran horizontally across it, leaving her half blind. She growled at Toka after hitting him. It could seem that her canine teeth were exactly like a dog's as well. Her left arm was gone and her on remaining arm, she had claws instead of fingernails. Like Toka she was bare foot and had claws instead toenails.

"Really, you need to think before you act! What if Aizen managed to track us thanks to you taking her? Although he may have got better at fusing hollow and shinigami together, who is to say this girl will be a vizancar like us? She could be nothing more then a failure!" the dog woman yelled.

It was at this moment the dark green hair vizancar opened her mauve taupe color eyes and looked at them.

"Who are you and where am I?" she asked curiously.

"You do not remember anything?" Toka asked when he noticed her eyes were the same color. They were strange because normal vizancars had two separate eye colors.

The girl seemed to go into deep thought as she tried to pull up anything, but everything was fuzzy, even her name, which was all jumble around in her mind. It took a while, but she managed to at least get her name or what she believed to be her name in clear form in her head, if nothing else.

"I think I remember that my name is Runa Nelku, but that I…can not remember anything less as its all fuzzy" she told him.

"Amnesia, huh? Well that's understandable. I am still unable to remember much of about myself before become like this," Asami sighed.

"Did something happen to me? Am I sick? I'm not going to die am I?" Runa asked frantically looking from Toka to Asami for answers.

"No, kid, you are not going to die. From the looks of things you'll be just fine. Asami and I are going to take care of you from now on," the maroon hair vizancar told her as ruffled the part of her hair that wasn't covered by her Hollow mask.

"That's right. Toka and I are going to be taking care of you. Vizancar like us have to stick to together," Asami told her.

"Right, but what's a vizancar?" Runa asked with a confused look on her face.

"The two of us will tell you everything you need to know once we get to where we are going to be staying for the night," Toka replied as the three of them left the alley.

I would like to thank

Dragon FangX for suggestion this idea of story with fusion of Rukia with another bleach character and help out in getting the story off the ground with their ideas for Runa as well as coming up with calling the Shinigami/Hollow fusion vizancar.
