We'll Never Speak of This Again

Summary: Hibari Kyouya dies and wakes up in Hueco Mundo. (In which Kyouya becomes the Supreme Ruler of Hueco Mundo, averts an invasion or two and somehow transcends to be the most powerful being in the universe. There is love somewhere too, of course.)

(WARNINGS! KHR/Bleach crossover, AU, sporadic updates, insanity, Slash, BAMF-Kyouya, BAMF-Shinji, blood and gore (remember that Hollows eat people) this is set as Mature for safety as there will be death and cannibalism (among Hollows) so be warned now.)

Chapter 1

The world was completely desolate. There wasn't a sound to be heard, unless you counted the dying screams of agony coming from somewhere far below. In the sky, there hung a silent moon with no stars to be seen. The white sands of the endless desert rarely shifted and the entire place gave off a decidedly eerie atmosphere.

None of this mattered to Kyouya though.

At eighteen years old, Hibari Kyouya was one of the most dangerous people in Vongola and he knew it. Not that he liked to be told so, as it implied he was a part of Vongola when he really didn't care about it. He would admit (though only in the privacy of his mind) that he had come to respect the omnivore Tsunayoshi, but that was essentially it.

So the fact that he had been killed by a stray bullet was especially aggravating.

He frowned where he stood upon the corpse of some giant monster with a hole in its chest that had attacked him when he had first came to this dead world. Its talk about eating him had irritated him enough that he killed it, though it had taken him more time than he would have liked, as it seemed to be built entirely differently from humans. Yet, the beast was capable of speech and had acted somewhat intelligently, retreating back when it turned out he wasn't as easy to kill as it thought he was. Unfortunately, Kyouya had still been somewhat pissed about the fact that he was dead, which meant he had to leave his beloved Namimori, and so didn't let the creature be. In the process of taking out his anger on it, it had died on him and now here he was, standing on its head to see as far as possible in this strange land.

The entire thing was depressing and downright dreary. Kyouya wanted to get back to his home, to Namimori and his people, to Roll and Hibird. He knew very well it wasn't possible. Some things just didn't happen and coming back from the dead were one of them. Despite what other people thought, Kyouya did respect the natural laws. Dead was dead, no matter how you put it.

And Kyouya was most definitely dead.

He sighed and attached his tonfas back to his belt when he determined there were no more beasts close enough to be a danger. His previously white shirt was stained with blood, most of it coming from where the bullet had hit him in his chest, and his black slacks were crumpled and dirty from fighting in white sand. He pulled a hand through his black hair and started the process of climbing down from the beast. Halfway down, he thought fuck it, and jumped the rest of the way to the ground. The beast was at least three times as high as he was and oddly proportioned. He really didn't know how it had had any sense of balance, being built the way it was.

Then there was the weird white mask with strange squiggly black lines coloring it and the hole in its chest big enough that he could see right through it. It wasn't hard to understand that he was in some sort of afterlife. The question was if he was in hell or not as he had killed his share of people. Something he knew most people had a problem with.

It was as he was contemplating this that a strange hunger started gnawing at his stomach. He felt a scream catch in his throat as pain flooded his body. A soundless scream escaped him as felt his entire body shift and something start to grow on his face. The agony took over his entire being and for a few short precious moments, he didn't know who he was. He felt his body move and he watched with a detached sort of curiosity as his body grabbed ahold of one of the weird creature's (Hollow, something in him said) and tore a bloody bit of flesh from it with his teeth.

Normal people would probably be disgusted by it, but all Kyouya felt as he swallowed the still warm flesh was a disconnected feeling of curiosity. When the flesh settled in his stomach and the sense of power exploded, Kyouya didn't try to stop his body as it moved to eat the rest of the beast (Hollow). The bloody carnage finished some time later—as there was conceivably no way to track time in this world of decay—and Kyouya felt the new power settle and seethe inside of him. He ruthlessly squashed it down as it tried to get a hold of him and ignored the hunger that hadn't abated at all, despite eating a creature (Hollow) much bigger than him.

When he rose from where he had been crouched over the Hollow, his face feeling strange and a new power in his possession, Kyouya licked his lips and felt a mask, presumably similar to that of the other Hollow, meet his tongue. The numbness of his chest told him he most probably had a hole as well and with an irritated hiss, he stood straight and ignored the feeling of a tail dragging behind him.

Kyouya clenched his teeth shut when he had the inexplicable urge to roar, something which he was definitely not going to do, and instead took a step forward from the carcass of the dead Hollow he had spent the time eating. In front of him was an endless desert and there was nothing stopping Kyouya from doing what he wanted anymore. Behind the mask, a bloodthirsty smile curled his lips into something terrifying. He almost laughed as he gave off more of that strange new power that had settled into him and summoned himself more creatures to kill.

This was going to be fun.

— —

Around the small body of a new powerful adjuchas, a sea of corpses laid. The sand was colored red from blood and the dead carcasses were a sad sight to see, some with entire limbs tore straight off. They were covered in scratches from powerful claws digging into them and if their faces could be seen, they would look terrified. In the middle of this bloodbath, a lone Hollow stood, one of the many limbs torn off in his hands that he had recently been eating.

Kyouya had no sense of time in this strange dead world, he could only measure it by when he rested and when he killed, but he knew he had been dead for a while. He spent his time giving off reiatsu to call upon creatures which he could feast his hunger on and walking, trying to find some intelligent company. Kyouya was a solitary creature, but from time to time he got the urge to be around people, which was when he usually just summoned Kusakabe, but now there was no-one to be summoned. The Hollows he killed were all embarrassedly stupid and if he tried to be around then for longer then a few minutes, he'd kill them out of sheer annoyance at their presence. The omnivore had always insisted that he needed to learn to deal with his annoyance better.

Still, Kyouya mused, there had to be more intelligent Hollows somewhere in this desert that could appreciate the wonder that was silence.

Instead of laying down and basking in the spilled blood like he wanted to, Kyouya started walking again, knowing full well that scavengers—Hollows that weren't strong enough to kill anything on their own—were soon going to be feasting upon this sight. Kyouya was starting to think that being turned into a Hollow had only raised his desire to kill if the amount of time he lured himself stupid Hollows were anything to by.

Well, it was their own fault if they fell for it.

Kyouya clicked his teeth in irritation as he felt Hollows swarm the corpses of the creatures he had just spent the last couple of hours killing but didn't turn around to look. The hunger was still present, as it always was, and Kyouya found the idea that it was Hollows attempt to find something that had been lost that made them hungry all the time to be stupid and idiotic, but he couldn't deny the fact that he was hungry and he apparently didn't have a heart anymore. He didn't know if that meant that it was just dead and not beating or if it meant that he actually didn't have one anymore.

Nonetheless, Kyouya was annoyed at the constant hunger that made him salivate at the thought of eating more creatures and made him sometimes lose himself in the process of killing things. He wasn't used to losing control like that and he didn't like it.

He bit back a snarl and concentrated on just walking. Despite the downright gloomy atmosphere the desert world that he had learned was called Hueco Mundo from another Hollow right before he killed it radiated, there was something calming in just walking. He breathed in the scent of death and decay that covered the entire plane and although he had the brief thought to open a garganta and just leave the dimension that he had found himself in after being killed, he ignored it and instead tried to pinpoint the sense of strong reiatsu that he could feel somewhere to his right, passed the many dunes of sand.

Recently, he had gotten better at sensing things other then himself and although his accuracy still needed a lot of work, he was much better than he used to be when he first came here. He had gotten help, if it could be called that, from a Hollow that he had trapped and, as a nod to their help, had then left trapped alive behind him. He didn't particularly care what had happened to it after that.

He tilted his head as he turned around to face the direction from which the strong sense of reiatsu gathered and after contemplating it for a while, he decided to go ahead and see if they could be worth something. The idea that he was desperate enough for company that he would willingly walk towards another Hollow made him grit his teeth and snarl soundlessly, but he was passed the point of redemption a long time ago. He didn't think even the omnivore would forgive him for everything he had done in this realm, no matter how forgiving he was.

So he started walking off in the direction of this other Hollow and started making his way past what seemed like an endless supply of sand. He knew that there was more Hollows, stronger ones, gathered underground in a place called the Menos Forest, but at this moment, he saw no reason to go there. He wanted to meet this new presence, that if he were a lesser Hollow would have made his hair (or fur in some cases) stand in fear, and he was going to.

The walk seemed to take forever, as Kyouya was point blank refusing to run, especially not when he didn't know what he was running to. Instead, he took his time eating Hollows that crossed his path and luring them in when he was too hungry to care that it wasn't something he would have done had he been alive. He wouldn't have needed to. When a sandstorm passed him, he hid in a convenient cave that had signs of once having been inhabited, but as he felt no-one else's presence in it, he assumed whatever had lived there was long gone.

He past time humming the Namimori Middle song when he was bored and looking up at the starless sky. He imagined that it would be hard to navigate in this world if he couldn't feel others, but didn't give it much thought. From time to time, he just sat in the white sand and contemplated life, something he didn't do when he was alive. But that was the keyword, wasn't it? Was.

Kyouya was very much dead and nothing was going to change it. To be completely honest, he wasn't sure if he even wanted to. He didn't know how much time had passed in the living world, but he didn't doubt that everyone that mattered to him had already moved on from his death and there would be no use in trying to come back to life. The few people who he cared for were strong and a thing like him dying wasn't going to hold them down for long. Rather he imagined they had already gotten revenge for his death and so there was no reason for him to do so.

No, he was going to carve himself a place in this new world of endless night and that was that.

Kyouya turned his head around when he felt the presence that had been in one place for so long begin to move. He narrowed his eyes and let out a low curse as he felt the being start making its way away from him, irritated that it didn't consider him worthy to meet. Considering the amount of reiatsu he could feel from it, he probably shouldn't be mad that he didn't get a chance to meet it, but if he spent his afterlife avoiding carnivores, he wouldn't get to have any satisfactory fights and than it just wouldn't be worth it.

He was already dead, if he wanted to pick fight with creatures he had never met before and that he didn't know the strength of, then he was going to.

He picked up speed as he continued following behind the fleeing Hollow that he was determined to meet (because it was fleeing, though he had no idea why when it was that strong) and his eyes were narrowed in fury. Kyouya knew he could be terrifying when he was mad, the omnivore had told him that often enough, but he didn't think he had ever been this angry before. This fleeing Hollow was the first interesting thing that had appeared in this decayed world and it thought he would just let it go?

Kyouya was a very good hunter when he wanted to be and he put it to good use as he followed the Hollow. Inside he was seething with rage at the thought of the monotone boredom that would take a hold of him again if he let this creature flee and it only fueled his determination to catch it even higher.

An untold amount of time passed him by as he hunted after the strongest Hollow he could currently feel, even as it attempted to hide from him by hiding its reiatsu, Kyouya kept on track and continued after it. He was determined to catch it, if only because he wanted to laugh in its face once it found it had been caught. When things ran away from him, it only made him want to chase it, if only to prove he was better at hunting than it was at running. And so, he only rested long enough to get his energy back and ate when he came upon Hollows too stupid to run away from him. For once, he was actually running and not luring in Hollows as he attempted to hide his spirit energy from the creature he was chasing.

There was no way to tell how much time had passed when he finally closed in on its location enough to be able to tell it wasn't very far from him at all. It had done a good job of hiding its reiatsu, but the Hollow simply had so much that even hiding it didn't do much in the long run.

As he got closer and slowed down now that he could tell it was no longer attempting to run from him, probably resigned to its fate, Kyouya began to feel reiatsu press down on him as he neared it. For a while now, the Hollows that crossed his path were already dead and although he had found it slightly odd, he had thought the being he was chasing had simply killed them. And he had had no compunction of eating them.

Yet, as he felt the reiatsu press down on his being, almost forcing him to his knees if he wasn't so stubborn, he began to think that maybe the reiatsu was the reason they were dead. He made his way closer and closer around the dune the creature was hiding behind—though he was starting to doubt what it was hiding from—and Kyouya felt as if an entire world was dropped on his shoulders. To his irritation, his legs started to shake from trying to hold his weight and when he felt himself starting to get light-headed and dizzy, he did something he had not done since dying. He called upon his Cloud Flames.

They were different and for a moment, he thought he might not have them anymore, but no, they were definitely there. With a smile that he usually never wore, he searched inside himself as he grabbed ahold of his flames. Flames were the power of the soul, it was a persons Will and although it had changed with his death, they were still there.

As his knees hit the ground and black spots started to form in front of his eyes, he grabbed at the Cloud Flames he still had and with a frustrated curse, guided them to that place where he could feel his reiryoku gathered. For a second, he thought that it wouldn't work, that he was going to die just because this being was so much more powerful (though he absolutely hated to admit it) but then he felt something in him change again as his flames got to work.

He was tempted to let out a roar in victory and a slightly unhinged laugh as he felt his reiryoku begin to multiply inside of him.

The multiplying picked up speed as he figured out how to do it right and before long, he let out a soft breath and opened his closed eyes to see a bewildered looking man standing in front of his kneeling form. Kyouya scowled and made to get to his feet as fast as he could, having no desire to kneel to anybody.

He watched, irritated as he saw the man in front of him was taller then he was, as the man looked him up and down, doubtlessly thinking he was too weak to have survived his pressing reiatsu, that still fought to push him down and kill him. Kyouya scowled behind his mask, not that it could be seen, and glared at the man with shoulder length dark hair and the bottom of a mask clinging to his neck.

"So," he demanded, no longer surprised at the guttural sound his voice made. "tell me why you were running from me."

The man only blinked at the sound of his voice and sat down on the sand, seeming to still be surprised that Kyouya was alive."My reiatsu...no-one survives it. Why aren't you dead?"

"I can multiply my own reiatsu." Kyouya stated bluntly.

The other Hollows eyes widened in disbelief while Kyouya studied the being in front of him. He looked scruffy and his hair was shaggy, like he had recently been sleeping. The clothes he wore were in much better condition then his own and Kyouya was starting to wonder if he should just go to the Living World and steal some new ones, as the blood was impossible to get out, as there was virtually no water in this world, and they were in pieces anyway.

It was a thought that bore considering.

— —

Some time later, they were both sitting on the ground as they rested in silence, Kyouya's need for companionship finally satisfied. From what he could tell from the short stilted conversations they had had, Starrk, as that was apparently its name, apparently longed for company as his heavy reiatsu meant that most Hollows died when they got within a certain radius of him. As long as Starrk knew that Kyouya wasn't going to stay with hm for any great length of time, then Kyouya supposed that he could track this Hollow down when his urge for comfortable silence in the presence of another acted up again.

Kyouya studied the moon in the sky that he had come to realize was the only true measure of time passing, as the moon went from full moon to new moon and back again.

It was a monochrome world.

And so for a time, he stayed with Starrk and his silence. Starrk seemed satisfied with Kyouya just being near him but after awhile, Kyouya started to get restless. There was a reason he had not stayed in one of the hideouts he had found while walking. He enjoyed it too much. Kyouya supposed that it could be blamed on the fact that he was a Cloud, but considering he had not seen his parents for years before he died, he thought it was just a Hibari thing. So after some time, he made his way away from the dune he had spent the last month or so resting in with the first intelligent Hollow he had found. It was a shame that Starrk insisted on being an omnivore.

Kyouya walked off in a random direction, again missing Roll and Hibird, but he had already decided that he wasn't yet going to the Living World. When his pants finally tore beyond repair, he would entertain the thought again, but for the moment, he was content to explore the seemly endless desert.

The irritation caused by his long hair swaying in a breeze that brought sand with it made him scowl, and resolutely walk away.

Kyouya stalked the white sands as he pinpointed a moderately strong reiatsu off somewhere in front of him and with a bloodthirsty grin, he followed it. He was hungry and it had been quite some time since he last ate. He had found that he enjoyed hunting his meals more then he liked luring them in. A slightly unhinged laugh escaped him as he walked towards his new meal.

He was going to enjoy this.

A/N: So I am very much aware I should probably work on my already existing stories, but well, I just couldn't not write this. This is my first time writing both Bleach and KHR, so feedback would be very much appreciated. Also, I feel like I should mention one more time that updates will be sporadic. I have no schedule for when I write.

Thank you so much for reading, I hope you enjoyed it!
