Chapter One: Gillian

Hollow...

That was how he felt when he first awoke, hollow, empty. He didn't know how long he had been unconscious, or why he was unconscious in the first place, but he definitely knew he was somewhere he didn't belong.

'How did I get here?' Naruto wondered as he looked around 'Where am I?'

All around him was a sea of endless white sand, as far as he could see there were just dunes of pure white sand, above him a full moon shone in the night sky illuminating the land and giving it an eerie tinge.

'What happened? The last thing I remember was...' Naruto's eyes widened as his memories returned.

He was dead!

He remembered defeating Sasuke at the Valley of the End and lifting the Uchiha onto his shoulders.

He remembered the sound of chirping birds before his chest exploded in pain and the world turned sideways.

He remembered floating above his corpse as his killer, Hatake Kakashi, spewed hate filled words at his body.

Naruto grimaced in pain and sadness as he remembered Kakashi's words.

"I hope you rot in hell demon, this is for my Sensei and all those you've murdered."

He had always thought Kakashi liked him, the man had always been kind to him and had never seemed to blame him for his tenants actions.

Obviously he had thought wrong.

He knew he should have been upset at this, he knew he should have felt sadness or even anger right now but he felt nothing, he was simply hollow.

'Where am I now? Is this hell?' Naruto wondered as he tried to stand, he found himself unable to stand as all four of his legs wobbled when he attempted it.

'Wait, four?'

Looking down at his frame Naruto sucked in a breath as he noticed his changed body. His body was no longer human, in fact he didn't even know what he was now, all he knew was that he was bone white in color, had four legs and three bone like tails.

As his mind panicked another memory came to the forefront of his thoughts causing him to gasp.

-Flashback-

He was falling, the chain on his chest had vanished moments ago bringing him a lot of pain. He could feel himself screaming as the pain spread from his chest but he couldn't hear his screams, they were being drowned out by another voice. This voice sounded deeper and was also screaming but not in pain, this voice was screaming in anger. Naruto cracked his eyes open as he felt something stir on his stomach, his eyes widened at what he saw.

A glowing ethereal hand was slowly withdrawing from his gut and in its grip was the source of the screaming, the Kyuubi no Yoko. His pain passed as they both stopped screaming and their eyes locked, Naruto was taken back by the powerful emotion he saw in the demons eyes; fear.

As quick as it had come, the moment ended and the demon was dragged away by a white gostly hand while he continued to fall, deeper and deeper into the darkness.

As he fell a small crimson glow began illuminating the darkness around him, Naruto looked towards the source and gasped when he saw it; his seal was still there and it was leaking crimson chakra. The glow increased in intensity as the familiar red chakra began to spread across his body.

'What's going on? I thought the Fox was gone.'

As soon as the thought passed through his mind the answer came to him. The Fox was gone, off to who knows where, but its power had remained.

Naruto's eyes widened as he watched the demonic chakra slowly crawl up his torso, as it reached his chest he felt something inside him crack and the next thing he knew the chakra was being sucked into the hole in his chest.

"What the he-" his comment was cut off as he felt a tremendous amount of pain, his head felt like it was splitting apart. He began screaming once more but it came out in gurgles as he felt something flowing up his throat.

He had enough time to see some white gunk flow out of his mouth before his world went dark.

-Flashback End-

'Kyuubi's gone?' Naruto wondered with wide eyes.

The demon had obviously been dragged off by the Shinigami which would mean it was either in the death gods gut or in hell. If Kyuubi was in hell then where was he? There was no way this was heaven.

Naruto sighed as he tried to stand once more, he felt strange...well, stranger. From his memories he knew he should have been feeling an onslaught of emotions right now but he felt nothing, his heart was blank and only that hollow feeling remained.

He managed to stand after a few tries and after getting used to moving with four legs he began walking, then running. It hadn't been all that hard learning to control his body, somehow he seemed to already have the instincts required and had just needed a little practice to wrap his mind around the concept. In fact, he could even move all three of his tails now, they trailed behind him lazily but he knew they could be used in an instant to attack or defend.

Looking back Naruto tried to get a good look at his new appearance, his body and tails, however, were the only parts of himself that he could examine without some kind of reflective surface.

He was now the size of a large horse but his body was canine in nature and looked like that of a Dog...or Fox. The only difference was that instead of skin and fur he was covered in some sort of hard bone like substance, his skin was hard to the touch but he could still feel his claws on his body.

Claws?

On each of his large paws he now had a set of long, sharp, black claws, he wasn't sure how strong they were but something told him that they were stronger than even the best kunai he had ever used.

His tails were the weirdest part of his new form, rather than three animal like tails, they each looked like an extension of his spine. Each tail seemed to be made out of various bone sections connected together, with the piece at the end sharpened to a point. Each tail was about three meters in length making them look large on his already large frame.

On his stomach, where his seal should have been, there was only a large hole that went all the way through his body. On the edges of the hole he could still see the tiny black seals that had once surrounded the spiral of his seal.

He couldn't see his face but he assumed it was canine in nature and from what he could feel, he guessed it was made of the same substance as his skin, although it felt a little harder than his skin.

All in all Naruto was quite sure he looked very strange.

'So hungry...'

It had been two days since he woke in this strange place.

One and a half days since the gnawing hunger had set in.

Thirty minutes since the ground had collapsed beneath him and he'd fallen into this strange forest.

Naruto trudged through the forest of stone trees looking for a way to satisfy his hunger, the entire time he had been here he hadn't run across a single other being or any food. Since entering the forest he could hear the sounds of...something...moaning and roaring as well as the sounds of smaller somethings fighting but he had yet to see anything at all.

His head perked up as he realized he was getting closer to the sounds of fighting, a delectable scent hit his nostrils and he felt himself salivate. His mind went blank as only the thought of ending his hunger filled him.

'FOOD!' Naruto took off running towards the scent, he weaved through the trees moving as fast as he could towards the sounds and smell.

Breaking through the tree line he was only a large white blur as he entered a clearing. He didn't even stop to stare at the large group of creatures fighting and feasting on one another, he simply dove in with a excited roar.

Lost in his hunger and blood-lust Naruto attacked anything in sight, he slaughtered and fed on the creatures surrounding him without pause. After several minutes he regained some sense of thought as the gnawing hunger lessened, he had killed and devoured three of the other creatures before his mind cleared.

With those kills had come information. He was a hollow. He was in Hueco Mundo, a realm occupied by hollows. Hollows ate other hollows or human souls to survive. Even as he absorbed this information Naruto continued to fight and eat learning more and more as he went. He knew he should feel some amount of revulsion about what he now was and what he was doing but yet he felt nothing. There was only that hollowness.

After several hours of fighting and eating Naruto seemed to build up a sort of routine, he would attack aggressively with his claws and teeth, taking down as many as he could at one time before stopping to feast. As he ate his eyes would roam about for new prey while his tails would lash out around him, keeping others away and killing those who came too close. With each fight he felt tired and weak but with each meal he was rejuvenated and stronger, he could feel his power rising and something told him he was nearing the next stage of his evolution.

As he finished with his newest meal Naruto glanced around for his next opponent. There were only five other hollows left within the clearing now, the rest having fled or died.

On some unspoken agreement all six hollows broke off into pairs and began sizing each other up. Naruto found himself standing across from a large Ape like hollow, from the mask to its large feet, it looked every bit an Ape except it was white in color with some red markings on its mask. The hollow towered over him by a few feet and he could sense the amount of power it held, the Ape-hollow had more Reiryoku(Spiritual Energy) than he did but the gap between them was quite small, almost negligible even.

Crouching in preparation, both hollows seemed to wait for some sort of signal to begin, it came in the form of a snort from another hollow in the clearing. Naruto immediately streaked across the short distance between the two of them and ducked under a powerful punch from his opponent. Being faster than the Ape he was able to score three hits on its chest before he was forced to leap away.

Naruto frowned when he looked up and saw that his claws had only left small scratches on the Ape.

'Great, another one with tough skin' he grimaced, remembering an armadillo hollow he had faced a few hours ago. The hollow had been pretty weak but its hard skin and harder shell had made it difficult to kill.

Grinning to itself after it had examined the scratches, the Ape hollow lumbered forwards and shot a fist at him, Naruto dodged easily by side stepping to the left but he was caught off guard when the fist he'd avoided caused the ground to explode on impact. He was sent flying off to the side and he winced when he felt large chunks of stone and dirt impact his side, they were unable to pierce his skin but he felt the bones below break from the projectiles.

'At least two broken ribs' Naruto grimaced as he shakily returned to his feet 'I need to watch out for those fists, one hit is all he needs to kill me.'

Distracted by his thoughts, he was too slow to dodge as his enemy lobbed a large stone at him, the stone struck one of his legs heavily and he winced as he heard the bone break. He tried to hobble on his other three legs but collapsed in pain when this caused his broken ribs to shift.

Grinning widely, the Ape hollow walked over to its downed prey and Naruto growled as he felt its large fist lift him by the neck.

"Any final words Fox?" The Ape taunted as it cocked a fist aimed at his head.

'So I am a Fox.' Naruto thought as he tried to formulate a plan. His claws were useless against the Ape's tough skin, he couldn't use his teeth at this angle, that just left...

Naruto stared at the other hollow blankly as he settled on a plan, the Ape was still waiting for him to say something and he took those few seconds to prepare himself.

"Yeah, don't blink." He ground out. His deeper voice surprised him but he thrust those thoughts away as he attacked.

The Ape blinked in confusion at his words but its eyes soon widened as it saw two of Naruto's tails heading for its mask, it tried to drop him and dodge but the tails were too fast, the hollow died instantly as the two tails stabbed into the eye holes of its mask and came out the back of its skull.

Naruto landed on his three good legs, wincing in pain as his ribs shifted once more, and began to feast on the corpse before it could vanish, he sighed in relief as he felt his bones mending and his power rising exponentially. He had noticed that only a few, not all, of the other hollows had healed with each meal and none of those were even close to the speed his own wounds healed at, something he would thank the Kyuubi for if he ever came across it again.

With his wounds healed and his meal finished Naruto turned his attention to the other hollows in the clearing. There were only two others left and both were looking worse for wear.

The large Elephant like hollow was missing half its trunk and had a variety of gashes on its sides.

The smaller Spider like hollow was missing three of its legs and had a large cut down its back.

Both looked to be on their last legs even though their Reiryoku billowed powerfully around them, they had gained a large power boost from their kills but had not been healed like him. The two hollows stood across each other trying to force one another back with their Reiatsu (Spiritual Pressure), they were waiting for a perfect chance to strike.

Allowing a small smirk onto his normally blank visage, Naruto surrounded himself in his own Reiryoku but kept it compressed so they wouldn't sense him. He had found Reiryoku to be loads easier to use and control than chakra had been, it was mostly out of instinct but he had still perfected it by practicing; Reiryoku needed almost no control to use and only the slightest amount of control to suppress.

Crouching low, Naruto shot off towards the two hollows, a literal blur as he streaked across the clearing.

Surrounded in his own Reiryoku, he was able to throw off the Reiatsu from the two other hollows and move at his top speed. He choose to attack the Spider first since it was most likely the faster of the two, it was completely caught off guard when he dashed right past it and ripped off a chunk of its mask. Even as he kept moving, one of his tails finished off the Spider, turning it into Reishi (Spirit Particles) that he absorbed.

Not slowing in the slightest, Naruto swallowed the mask fragment in his mouth and headed straight for the Elephant hollow. He was a white blur as he jumped at the surprised hollow, his claws extended menacingly. His claws easily sunk into the weaker mask of his prey, while his tails stabbed into its body. One tail entered its side going for the heart, another went through its mask aiming for the brain, the last stabbed it randomly and repeatedly in an attempt to bleed it out.

The hollow put up a small struggle but it was no match for him and it toppled over dead after a few seconds, Naruto smirked again before he began devouring the hollow. As he ate, he felt his power rising and rising until it began to press against his body, it felt like the power was trying to fill him up but his body was far too small to hold it. The power kept pressing against his body and it soon began to feel painful, the pain increased in intensity and Naruto felt like he would explode at any moment.

Finally, he reached the breaking point and Naruto felt himself scream as his power overflowed, his body began to crack and a white light could be seen shining from within. With a final scream, his body exploded in white light leaving only his mask floating behind. For several seconds nothing happen, then with great speed, the mask shot straight up into the air, growing in size as it flew. Once the mask was several dozen meters in the air, a black cloth billowed out the back and dropped to the ground below, shrouding the body that grew within.

With his mind free of the pain, Naruto looked down on his new form and roared, he had evolved.

He was a Gillian.

"Grrrraaaawwwwrrrr!"

Naruto roared his challenge at the other Gillians within the forest, most lumbered about mindlessly, feasting on what they could, but a few were attacking anything in sight; those were the ones that had distinct masks. He had been a Gillian for close to three weeks now and Naruto had to admit it sucked, it was a constant battle between the gnawing hunger and the voices in his mind, no matter what he did, the voices were constantly there, trying to drive him crazy and take over his body. Unfortunately for them, he had been well known for his stubbornness and nigh unbreakable will when he still lived, each time the voices rose up, he would quickly and viciously beat them back down. Sadly, he was reaching his limit and he couldn't take much more of this, he sure as hell wouldn't miss being a Gillian when he evolved.

"Grrrraaaawwwwrrrr!"

With another roar, Naruto lumbered towards a small group of plain-masked Gillians, those that had lost the fight against the voices. With each step, he called on his willpower and Reiryoku to force the voices down and sharpen his mind. The group of Gillians lumbered about clumsily as he approached, none even bothered to look up as he descended on them.

Naruto lunged forward at the first Gillian and managed to bite off a large chunk of its mask, killing it instantly and reducing it to dust. Its death drew the attention of the others and they lumbered towards him, a few roared as they neared but Naruto paid it no mind as he focused his Reiryoku, pouring as much power as he required towards his mouth. His maw snapped open and a ball of red Reiryoku began to form, he waited until the Gillians were closer and the ball reached its limit before releasing the pent up power, firing his most powerful attack.

The Cero.

The blast tore through one of the mindless Gillians like a hot knife through butter and continued on, cutting down hollow after hollow. Rather than fire it in a single burst like most Gillians tended to do, Naruto preferred to continuously pour Reiryoku into the Cero, keeping the beam active for as long as he required it. It took him just a few seconds to cut down the horde of Gillians, a feat most others would find difficult to match.

With his opponents dead, Naruto cut off the Cero beam and quickly began feasting, he'd avoided causing damage to the masks so the bodies would remain for quite a while. Feasting hungrily, he made it through six of the corpses before a familiar pain began to spread through his body, evolution at last.

Excited to be rid of the voices that plagued his psyche, Naruto tilted his head backwards and released a powerful roar as he was once again enveloped in white light. The Gillian sized being of light began shrinking rapidly as Naruto's roar tapered off, the light condensing into a smaller form before it vanished entirely, revealing the newly formed Adjuchas.

As his transformation came to an end, Naruto released a relieved sigh, the voices were finally gone. Somewhat excited at his latest transformation, he stalked over to a nearby quartz tree and examined his reflection. His new appearance was similar to his first, except he now stood upright on two feet, with six bone tails swinging behind him.

He stood at close to eight feet tall, with an extremely large, muscular torso. His skin was completely white in color, but he had black markings trailing across his torso and legs, starting from the hole in his gut (The markings from the golden Kyuubi cloak). On his face was a white fox mask, with two large eye-holes, revealing his golden hollow eyes on a backdrop of pitch black nothingness.

All in all, it was quite an impressive form.

Smirking at his new body, Naruto raised one hand and took a swipe at the crystal tree, extending his blackened claws as he did so. His claws easily carved deep gashes into the tree, causing him to chuckle as his new found power swirled around him.

-Elsewhere-

Inside a large room, human skeleton draped in a purple cloak with a tattered pitch-black fur collar around the neck area and fringes lounged on a throne made of deformed skeletons, on top of the skeletons head was a golden, jeweled crown.

Kneeling below the throne was a large Crab-like hollow.

"So, he has reached Adjuchas level?" The skeleton hollow rumbled with slight amusement in its tone.

"Yes, your majesty." The Crab replied evenly.

"And in just under a month? Quite impressive." The skeleton mumbled, a hint of malice creeping into his tone. "Take your squad and find this Fox hollow, offer him a place within my army."

The Crab looked up at the throne, eyes glinting in the light,

"If he should refuse?'' It asked.

The skeleton snorted as it stood, easily towering above the other hollow.

"Then destroy him." He commanded, turning away from the Crab hollow.

"Yes, King Barragan." The Crab replied silently as he went to gather the hollows needed for the job.
