AN: I am currently going through a craving for HPxBleach stories. Unfortunately there's not a lot of good quality stories with this crossover, even though there's so much potential for it. So, I went ahead and wrote something. I hope to continue this, but unfortunately this hasn't been really fleshed out.

I'm not the type of person to give hints as to where my story will be going. However, I would like to point out that there will be No Slash. I do not do much romance scenes, due to the fact that I suck at writing such scenes. It might change later on, but definitely not anytime soon.

I hope you enjoy. I welcome any constructive criticism, especially if you notice grammar errors.

The first thing Harry Potter saw was the sky. It was daytime, around noon. Thin clouds drifted by. He heard the rustling trees and muted chatter a bit far. He felt the uneven ground irritating his back.

And finally he remembered that he died.

He kept looking up at the sky, not moving nor seeing. The sudden awareness of his death was a punch to the gut. He's dead, he knows he's dead. He remembers the pain of his magic crying to get out. The warning tingle reverberated through him, until his body exploded and destroyed everything within a 100 meter radius. The last few moments alive were painful and terrifying, but he wouldn't change it for the world. It was worth it, his death. For Voldemort went down with him.

Harry sat up when he finally calmed his mind. At the end he was certain of two important facts.

He died.

And that he was denied the chance to be with his friends and family in the afterlife.

Yamamoto Genryūsai Shigekuni, founder of the Gotei 13 and Captain-Commander of said organization, was in the middle of his favorite past times; checking out this years' incoming students of Shin'ō Academy (which he founded and even taught there for a time). Yamamoto loved checking on the students like a grandfather loved seeing new grandchildren. His eyes crinkled whenever he saw their eyes lighten up after performing their first kido spell perfectly. A couple times his thick white moustache helped hide his grin when a child would make a hilarious blunder. His current favorite was when one student had a hakuda match while he was still clearly wasted. The moves he performed to win the match were… unique.

Ah, youth.

Surveying the small body of nervous students, Yamamoto focused on checking their reiryoku. So far, all of them had a decent amount. He was happy to note that a good handful had reiryoku levels close to seated officers. There were no prodigies in this new batch; then again, prodigies only come once a century. Hitsugaya was the last…

Wait.

Old eyes sharpened and looked at one particular student. The child looked average. Black hair, slightly shorter than his peers. He looked frail, but then Ukitake Jūshirō looked frail and was still hailed as one of Gotei's most powerful captains.

That brat, he thought, He's controlling his reiryoku! What was even more surprising was that this boy, this child, manipulated it in a way that made it seem that he didn't exist! He doubted even Kyōraku Shunsui, one of the best at sensing Reiryoku, would have noticed this strange phenomenon unless he was told beforehand. Yamamoto's eyes narrowed and prodded deeper.

So tightly controlled, he couldn't have been self-taught! One of the captains must have found him and taken the child under their wing. A deeper look and… a shikai! Already? Then why isn't he already part of the Gotei 13? None of his captains would have shipped him off to the Academy if this child already achieved shikai. Not even the currently missing Shihōin-

All thoughts were brought to a standstill when cold, green eyes straight straight into Yamamoto's own. Tension coiled between the two, the boy's shoulders tensing and eyeing Yamamoto's stoic stature. Then the impossible happened.

The child's reiryoku simply disappeared.

Yamamoto's eyes widened in astonishment, his jaw slackening at the bewildering situation occurring. No one should have been able to fully hide their reiryoku from him! He could feel every soul within Sereitai if he wished, but he can't sense this one boy still wet behind the ears? He kept on prodding deeper, bringing forth spirit ribbons to search for the child's thread but only proving that it wasn't there. It was almost as if he didn't exist! With each failed attempt Yamamoto looked at the boy to make sure the boy's chest rose up and down to show he was breathing.

After his last attempt of using reiraku, Yamamoto saw the child's face changed. Instead of the cold glares, his green eyes were now sparkling in amusement. The child knew what he was doing.

Before the Captain Commander could pursue the anomaly further the front doors of the Academy opened, allowing the students to enter and attend their opening ceremony. With one last taunt, the child gave a jaunty wave (such a disrespectful little child…) and followed the rest of the students inside the academy.

As the front doors slid closed Yamamoto knew that this green-eyed child will make waves in Sereitai for years to come.

"Soutaichou? is something bothering you?" If Nanao-chan heard such respect coming out of his mouth, Shunsui thought, then his poor lieutenant would have had a heart attack. But his old teacher's unusual behaviour concerned him and his good friend Jūshirō.

The three always met in Yamamoto's office every week for idle chatter and the occasional lecture their old sensei would give to them. It was a routine that the three coveted mostly because of their close relationship. However, for the past six meetings Yamamoto was acting odd. The captain was constantly distracted lately, always looking out of his office window and staring off into the distance. Many times Shunsui felt his sensei check his reiryoku, almost as if he was making sure he was still alive. He asked Jūshirō one time if Yamamoto did the same to him, and his friend believed that Yamamoto was checking him more than Shunsui.

The old Captain let out a sigh, idly tapping his staff on the floor. "You could say that, Shunsui." Yamamoto's brows furrowed as he thought of a way to explain what exactly was troubling him. He eventually straightened up from his seat.

"Tell me Kyōraku, Ukitake."His hands clasped together and tightened his grip on his wooden staff. "Have you ever met a newly recruited shinigami that could completely hide their reiatsu?"

Shunsui frowned, scratching his stubbled chin. "Can't say I have," He answered. "Oh I've had the few fresh recruits that unconsciously lessen the amount of reiatsu they spilled outward, but never to the extent you're asking."

Ukitake nodded in agreement. "Byakuya-taichou was the closest in suppressing his reiatsu, but he was trained at a young age. For one not born of nobility, Hitsugaya-taichou comes to mind. Even still, Isshin-taichou had to teach him how to suppress his reiatsu. Besides," Ukitake looked at the Captain Commander with a raised eyebrow. "Wasn't it you that told us that it's impossible for someone to completely hide their reiatsu?"

"Ah, I believe I heard him tell us that. Something like completely hiding one's presence is impossible, because it'll mean that they're dead?"

He saw The Captain Commander's mouth twitched at Shunsui's lazy explanation. Of course Shunsui remembered this lecture; Yamamoto made sure that the lecture was ingrained in his mind.

"Yes, which brings up to my current… conundrum." Yamamoto turned and looked out through his office window, his gaze directed toward the general direction of the Academy.

There was a moment of silence, with Shunsui and Ukitake surreptitiously trying to see where their old sensei kept on looking to.

Yamamoto let out a sigh. "Well, I believe that showing will make it easier to believe than explaining." The old man stood up, looking at the two other captains. "Shall we move our conversation closer to the Academy? I believe that what you'll witness will be quite… eye opening."

He was there again, that weird old man. Always with his wooden cane that he obviously didn't need to keep himself upright. Always focusing his little reiryoku probes on him whenever he was about to cast a kido spell or practice his hoho. If this keeps up, Harry thought, then he'll have to confront that old geezer and tell him politely that he doesn't take kindly to pedophiles.

"Kago, stop spacing out! Perhaps If you focused more than going into your own little world, your zanpakutou would have taken form by now!" He ignored the sniggers of his classmates and let out a huff. Of course that bastard of a sensei picked on him. He was the only one in his year that still had a blank sword.

"Yes, sensei~"

Clonk!

"Brat, be more respectful to your betters!" Harry would be more respectful if he didn't have an old man stalking him and teachers that are only good at screaming at people's faces.

Insolent mortal, how dare you hurt MY master! Beautiful, beautiful master… Oh how magnificent it'll be, my master, to have this mortal writhing in the ground, begging and BEGGING

Harry ruthlessly closed off his zanpakutou from his mind once more, suppressing the cold shiver that raced down his spine. According to the Academy teachers, meeting your zanpakutou spirit is the most 'magical' moment of your life. That day should be exhilarating, awe-inspiring, enlightening to your true self.

Well, it was enlightening in a sense.

The first time Harry met his zanpakutou, he didn't even know who he was. All he saw was a crazed maniac proclaiming that from then on, he will always be with him. Now if this proclamation was said by a normal looking person or heck, even a bloody snake, he wouldn't have minded. But this was said by Kuroshibyō, Black Death. This was said by a man with a missing right eye, and sickly pale skin. This was said by a thing with half of its body emaciated, the other half bones and no skin.

It didn't help that right after that meeting,Harry was thrown back to reality feeling mind-numbing pain through his entire body. It was worse than being put under the cruciatus curse, on par with the build-up of his explosive death. And as he screamed and screamed and screamed, all he heard inside his mind was this crazed maniac. This zanpakutou, Black Death, Kuroshibyō, laughing and laughing and laughing.

So no, the meeting with his zanpakutou wasn't filled with rainbow shitting unicorns.

"KAGO!"

Clonk!

Goddamnit, he can't take much of this abuse anymore.

"Sorry sensei,"

"Saying sorry won't change the fact that you still haven't finished your katas!" The instructor let out a sigh, leaning on his zanpakutou. It was clear that Ueno-sensei was tired of having to teach a 'worthless student'.

The fairly large sensei levelled a glare at Harry. "As punishment for not concentrating again, your kata exercises will be doubled from now on until your zanpakutou manifests. You are also to complete the new regime today, and clean up this place once you're done."

As if trying to intimidate him, Ueno-sensei leaned forward until their noses were inches away from touching. "And I will know if you're cutting corners, Kago. got it?"

"Yes sir." The instructor was still displeased with Harry's nonchalant reply, but still called the lesson for everyone (except Harry) finished.

He ignored his classmates' relieved sighs, and the arrogant few that shot barbed comments about his 'shoddy sword swings'. Harry wasn't interested in acing every lesson like some prodigy. In the end the Academy was a place to waste his time. A place for him to adjust to his current shitty situation.

When the last of his classmates left the courtyard, Harry started going through the kata exercises. With each swing he placed more strength to it. With each step he made sure that his footwork was cleaner, sharper. As the seconds passed by his swordsmanship became more fluid, more -

"Don't you think it's a bad idea hiding your potential from Ueno-sensei , young man?"

Ah, almost forgot about the old man. At least with this guy, he could show a bit more of his real personality.

Harry just stopped himself from jumping when he found the same old man was five feet away from him.

He must have been a captain before he retired, Harry thought.

Harry lowered his sword and sent a scathing glare at the old stranger. "What do you want, you old geezer?"

Said geezer raised one eyebrow up, "Quite rude, youngsters are these days."

His eye twitch, "Oh I have every right to be rude, you weird pedo. Why do you keep on showing up here and sending your bloody probes on me?"

Stifled laughter from his right caught Harry off-guard once again, making him turn around to see the source of the noise. Two more men were walking toward him. While they were not ancient like the creeper, they were clearly older than most of his teachers in the Academy.

Harry looked back at the old man. "More creepers?"

The guy just had the audacity to laugh at Harry's face.

Honestly, this was the most fun Yamamoto had for a long while. Even before the Gotei 13 was formally established, he was respected and awed by all. He saw the admiration more of a curse than a blessing. For how can the Gotei 13 continuously evolve and improve if everyone took his suggestions as law?

The only people left who would casually speak to him were his two old students and his Lieutenant, Chōjirō Sasakibe. Even still, the three wouldn't dare insult him so casually like this young boy in front him.

Who was currently trying to give him a stink eye. Honestly, Yamamoto just managed to stop himself from pinching the boy's cheeks. So adorable, trying to intimidate him!

"Those two 'creepers' happen to be my former students." Yamamoto replied.

The child scoffed. "Oh, so now you're also teaching others how to stalk young innocent Academy students?" The boy's green eyes widened for a fraction of a second, shoulders hunching, before he swung around and glared at Shunsui.

"Oi, that still doesn't give you the right to bloody probe me!"

Shunsui blinked in surprise. "You can sense them?"

"Of course I can! You were less subtle than your pervert of a sensei here."

And now Yamamoto could see the interesting glint in the two captain's eyes. when he brought Shunsui and Jūshirō to watch a couple first years in the Academy going through a zanjutsu lesson, the two were puzzled and unimpressed at what they saw. They believed they were going to be introduced to another Gin or Hitsugaya, flying through their katas and blowing away their peers through their sheer presence. After dropping some hints, the two begrudgingly (more in Shunsui's side) stuck around, even after the class ended and all but the 'incompetent' student left the courtyard.

And that's when the boy showed his skill.

The movements were fluid as the boy flawlessly went through the stances. Each step he took barely rustled the dust in the ground, every swing with his zanpakutou made the air sing. It was simply beautiful.

With just his zanjutsu skills, Shunsui and Jūshirō would have checked the boy as a potential seated officer. The fact this young first year knew Shunsui was checking his reiryoku, though, had his two captains know that this child could easily become Captain material. Now their curiosity was definitely peaked.

"You must have excellent control of your reiryoku, child, if you were able to sense Shunsui."

A scoff, "Please, they're your students. They learned from you. Naturally I'd be able to tell sense him if I could sense your little probes." The boy then turned back to him, "And just so you know, jeezer, I'm not a child. You no doubt heard Ueno-sensei yelling out my name to the heavens a while ago, so use it."

Yamamoto stared right back, his eyes glittering in mirth instead. "I will use your name, child, once you ask who we are instead of thinking up of interesting nicknames for us."

"All I need to know about you guys is that you're old retired men that are so bored at home that you spend your time checking the future shinigami troops to reminisce of the good 'old days'."

Jūshirō spluttered, "retired?! You think we're retired?!"

And finally a flash of fear passed by the boy's face. His grip on his sword handle tightened to the point that his knuckles whitened. His green eyes, usually glittering with mirth, was impossibly wide and full of fear.

"Wait, you're still shinigami?" The boy focused those eyes on Yamamoto, as if pleading that what Jūshirō said was a lie.

Yamamoto just gave the boy a bland smile. Looks like he'll have to accelerate his plan a bit more than he would have liked.

"Ryūjin Jakka's shikai hasn't been released in over a century." He tapped his wooden staff on the ground. "Let's have a spar, boy."

"You didn't answer my question."

Yamamoto let a bit of his reiatsu out, enough to have unseated shinigami officers to fall to their knees. As he expected, the boy didn't even feel the change in the air.

"Yama-" He cut off Jūshirō before he could continue.

"I'll answer your question after the spar."

"So you guys are still officers!"

"No, the three of us are not shinigami officers." We're captains, Yamamoto thought.

The boy's instinct was sharp, for he still felt something was amiss. His eyes darted toward Jūshirō and Shunsui, the latter tilting his sakkat to hide his sharp grey eyes while the former was squirming to speak up. It was obvious that Jūshirō believed the spar shouldn't happen; he still believed the child was not strong enough to handle Ryūjin.

But it seemed that Shunsui had a similar hunch with his own; the boy still has more power than what he revealed to them.

"Oi you, whitey, what were you gonna say?" The boy was stalling for time; more like grasping at straws.

"Let's start, shall we, Kago?" Holding his staff in the air, the wood burned away to reveal his the real form of his zanpakutou.

"Wait, you're going to release your shikai to - "

Six beams of light suddenly appeared and slammed into Ukitake's midsection, stopping the 13th Captain who was seconds from jumping into the fray.

"Bakudō 61: Rikujōkōrō"

"Shunsui?!"

"Just watch, Jūshirō. The boy's more capable than you think…"

At that point the boy was entirely spooked. "W-what the hell! I'm getting out of here!" Wrong thing to say to an opponent, Yamamoto thought. It just makes them strike faster.

Before the boy could so much as think of using shunpo, Yamamoto slid his sword from its sheathe. "Reduce All Creation to Ash, Ryūjin Jakka."

It was still. Oh so still.

Then the Academy building groaned with the sheer weight of the reiatsu coming forth from his zanpakutou's release. Yamamoto could hear cries coming from inside the building as students and shinigami were forced to go to their knees from his reiatsu. Closer to the center of Sereitai all of his captains no doubt felt the release of his shikai; Unohana-taichou was already shunpo-ing toward the Academy to help the unfortunate souls cope with Ryūjin's sheer presence. But for Kago, who was just a few feet away from him…

Kago wasn't even effected by the release of potent reiatsu.

No, what the boy focused on was the fire engulfing Yamamoto's blade. Beads of sweat started to form on the boy's brow as took a step away from the heat.

The child was effected by the heat of an inferno five feet away from him, and not the reiatsu that was enveloping the whole courtyard.

Yamamoto couldn't help the smile stretching across his face. Yes, this boy's extremely powerful.

"Get ready," That was the only warning Yamamoto gave before he shunpoed behind the boy and swung his sword down on the boy.

Red.

Orange.

White.

Those were the only three colors that Harry could see at the moment. The colors that seemed to be what fire consists of.

Fuck, Harry thought as he stepped away from the old man and wiped the sweat already forming on his brow. Fuck. My. Life.

What is up with old men wanting to kill me?! He thought he was done having that type of problem; Dumbledore was dead, and Voldemort exploded when Harry's body exploded. So why did he had to have a Dumbledore-esque man wanting to fry him to a crisp?

At least the other two jeezers aren't vying to kill me. In fact, said two were jumping away, one of them held in a bakudo spell while the other held tight to his straw hat. No doubt they'd be shunpoing right back if I managed to kill this pyromaniac first.

Harry was brought back to the present when the old man said, "Get ready." Harry gripped his sword tighter, looking forward and ready to block a strike -

Only to find the man was now behind him, the fiery blade drawing ever so closer to his open back.

Fuck!

He knew at that second it was over. His life, his dreams of finishing the Academy in six years and becoming a shinigami officer after going down the drain.

It was over the minute he felt blood erupting from his back and he opened his mouth.

With one more reiatsu surge the bakudo spell collapsed and Ukitake Jūshirō was free.

Free to sheathe his zanpakutou and point it at his friend. "Shunsui," Jūshiro growled, "Give me one good reason why I should not strike you for allowing the soutaichou to release Ryūjin at a student."

His fellow Captain just tilted his hat upward, staring back at him. Jūshiro just pressed his blade closer to his friend's neck. "Shunsui…"

The 8th Captain opened his mouth, no doubt to give a half-assed answer. Because in the end, the boy was dead. No one could handle the heat of Yamamoto's shikai at full blast; not even he and Shunsui could. It was a waste of a potentially strong shinigami, a waste of a young boy.

"Spread Despair Across the Lands, Kuroshibyō."

In an instant the immense reiatsu was gone. The sensation of large hands wrapping around his neck and ringing every breath from him evaporated in an instant. He could breathe normally again. The Academy structure stopped groaning and creaking. The sky looked bright again.

He knew what Shunsui was feeling at that moment, for he was thinking the same thing; what sort of monster was able to neutralise Ryūjin's reiatsu so easily?

"Well, your zanpakutou's form is quite unique Kago-kun."

"Heh, says the man with the fire sword." Jūshirō could barely feel his legs. His grip on his zanpakutou's handle was strong enough his fingers hurt. He didn't want to see, but his head still turned towards the courtyard. From the corner of his eye he could Shunsui do the same, holding his sakkat like a lifeline.

The scene before him was shocking enough to have Ukitake drop his zanpakutou.

Yamamoto chuckled, "Fire sword? is that all you can say?"

The boy laughed, has back still facing him. "I can't really think of anything witty to say, you crazy old man. I'm a bit pre-occupied at the moment."

Yamamoto doubted it; after all, both of the boy's hands were free. It was just his back, which had six black gleaming blades jutting out and tearing through the boy's white kosode that stopped his strike. The shape the blades formed made it looked as if the boy's ribcage popped out of his skin. Where the skin broke through dark red blood trickled down the boy's back.

Having such a zanpakutou that would make its weirder bleed with every time it is used would have made Yamamoto worry. But there were other more pressing concerns. Like the fact that his reiatsu was negated by the boy's own. Such a frightening zanpakutou Kago has, Yamamoto thought. Black Death; a fitting name for such a dangerous blade. Indeed, if any of his other captains faced this boy's blade, the true power of Kuroshibyō would have bled through. For the minute his blade clashed with Kuroshibyō, Ryūjin's fiery blaze spluttered to a stop. No, the zanpakutou wasn't dangerous just because the way it was wielded; it was dangerous because it sucks the energy of whatever or whomever touches it.

"Well," Yamamoto said, "I wonder what else can your zanpakutou do?" For one thing, no matter how much force he pushed on his Zanpakutou the boy wouldn't budge. Yamamoto shunpoed away and appeared in front of the boy. As expected the second the two zanpakutous stopped touching Ryūjin became alive again. He paused for just a second to let the boy see him before he attacked once again. That small pause should be enough for a boy of such caliber to react.

Sure enough just as he thought his blade would strike through he was brought to a screeching halt by the child's raised arms.

Ryūjin's fire was extinguished once again as the screeching of metal on metal filled the air. Hmm, it seems that his zanpakutou could also spread across his arms.

"Aaaargh!" Well at least this child wasn't some invisible deity. His arms can't handle so much weight.

Using this to his advantage Yamamoto pressed forward, placing more strength and having the boy fall to his knees.

"FUCK!" The boy's arms were trembling from the weight. Any second now the boy's arms would break and the spar would end. For it had to end; Unohano-taichou was almost here, and the Academy students were stomping towards where the reiatsu surge happened.

With one last push the boy's arms caved in followed by a long, drawn out scream. Yamamoto took a step back, sheathing his zanpakutou and raising his palm up towards Kago. "Bakudo 63: Sajō Sab-"

"Byakurai: Hebi no kousou."

Before he could react at the twisted kido spell, a stream of lighting in the form of a snake raced towards him and bit at the his shoulder. From the two puncture wounds the energy entered inside his body and electrocuted Yamamoto from the inside out.

The power of the kido was enough to have the Captain Commander fall on one knee and bite bottom lip to stop him from screaming.

It still wasn't enough to stop Yamamoto from casting a shō and Kyokkō at the boy, hiding Kago from Unohano who just arrived at the Academy's courtyard and the curious students and teachers entering the courtyard from its front doors.

"Yamamoto-taichou!"

"Soutaichou? He's here?!"

"Holy cow, Ukitake-taichou and Kyōraku-taichou are here too!"

As he allowed Unohana-taichou to heal his wound and heard Jūshirō and Shunsui spinning a lie as to why they visited the Academy, Yamamoto looked toward where he pushed the child - no, opponent - into. Yes, he was right from the moment his eyes fell on this boy. Kago will be making waves in Sereitei.
