Hey, new crossover idea, I'm not sure if it's been done or not, so I'll just go with it.

Bleach x Harry Potter! Harry instead of Ichigo, lets see how it works out.

If my Japanese is wrong, please correct me.

I need a Beta editor, if anyone wants to do that for me. And, it'd also be useful if they could complain, so that maybe I'd actually get some work done in the end, rather than just stopping my stories.

Harry Potter and the Duty of a Shinigami

Chapter 1: Hollow and Shinigami?

- - - - -

After fifth year, Harry Potter had been having a horrible time. During the summer, he lived at his relatives' house. His relatives who hated magic, and anything else abnormal.

Harry Potter was everything but normal, so his relatives continued to hate and despise everything about him.

For you see, Harry Potter was a wizard. He goes to Hogwarts School of Witchcraft and Wizardry. He was probably the most famous wizard this century, as he had defeated, at one year of age, the greatest dark wizard of the century, Voldemort..

Now, normally, this would be weird enough, but things had gotten worse since the end of the last school year.

At the end of the last school year, Harry had been sent a vision by the reborn Voldemort. This vision showed a horrible scene, Harry's godfather, captured and being tortured by Voldemort's followers, the Death Eaters. But it had been a lie, a fake vision, made to trick Harry into coming to the Department of Mysteries, where a prophecy lie in wait. A prophecy that connected Voldemort and Harry together.

Inside the Hall of Prophecy, Harry, Hermione, Ron, Neville, Ginny, and Luna fought off Death Eaters over twice their number for over a half an hour, before help arrived in the form of the Order of the Phoenix.

The Order and the Death Eaters faced off breaking into small battles all around. Sirius and his Death Eater cousin were embroiled in a battle, on the dais in the middle of the room that held a dark archway. Sirius ended up being thrown through the archway, which Harry later learned to be the Veil of Death. Nobody could come back after going through it.

After that, the memory became fuzzy to Harry, who had lost it. He had gone chasing after Bellatrix, who had cast the spell to send Sirius into the Veil. He had found her, knocked her over, and performed one of the darkest curses in existence on her, the Cruciatus curse. The spell worked marginally, for it failed after a few moments, and Harry realized he hadn't the heart to work such a horrible spell, even on the one who had ruined his life so badly. The curse required pure and utter hate; righteous anger would not power it.

Once that failed, the night had kept getting worse. Voldemort arrived on the scene, taunting Harry for failing the spell, and performing it perfectly on Harry. The torture was cut short when Headmaster Albus Dumbledore arrived, and fought Voldemort to a standstill. Voldemort pulled a trick out of his figurative hat at the last minute.

Through the connection forged by the failed Killing Curse sent at Harry as a baby, Voldemort possessed Harry's body. The wracking pains made him plead for death, more so than even the Cruciatus curse. But something in Harry's mind triggered him to think of Sirius. An overwhelming power flooded through him, full of love for his godfather. Voldemort was forcibly flung from his body, and he fled after quickly retrieving the collapsed Bellatrix.

Harry had been brought back to Dumbledore's office, and had been told of the prophecy that only he and Voldemort could touch, the one that had been shattered in the battle. Dumbledore had a record of it in his memories, and showed it to Harry on his Penseive. Harry watched wordlessly as the illusory form of Sybil Trelawney spoke of his destiny.

The one with power to vanquish the Dark Lord approaches…

Born to those who have thrice defied him…

Born as the seventh month dies…

And the Dark Lord will mark him as his equal,

But he will have Power the Dark Lord knows not…

And either must die at the hand of the other,

For neither can live with the other survives…

The one with power to vanquish the Dark Lord will be born

As the seventh month dies…

Thus goes the prophecy that had dictated Harry's life since birth.

Since that day, things had started to change around Harry. His moods became worse and worse, and he closed off more and more.

His friends became worried, and slightly afraid of this new Harry.

Harry had started to see ghosts after that day as well. This wasn't really unusual to Harry, as he lived in a world where ghosts were normal, but not this many. They were different kinds of ghosts though.

Rather than being the grayscale that most ghosts were, they were in full color, vibrant. On their chests, they had chains, coming from their hearts. It was the strangest thing.

But Harry had quickly gotten used to their presence. The grayscale-ghosts seemed to be able to see the other ghosts, and explained to Harry that ghosts lost color over time.

Once the year had ended, Harry had been sent back to the Dursley's, where he now resided. He had spent a few days wandering the neighborhood, against the wishes of Dumbledore, but for some reason, Harry couldn't bring himself to care.

But this was the day it was all going to change.

Harry awoke from his slumber without a nightmare accompanying him. This came as a surprise, as he had been having nightmares consistently every night since Sirius had died.

Harry sat up and stretched, popping several bones in his back. He released a sigh, and stood up, grabbing some clean clothes, and walking towards the bathroom. He wanted to take a shower before either of the fat lards he knew as relatives demanded him to make them breakfast.

Five minutes later, he stepped out of the shower, and looked into the mirror at himself. His upper body was covered in scars, remnants of the beatings he had received at the hands of the Dursleys before his Hogwarts letter. He growled. "Why do I keep getting sent back here? Aren't the wards based on love? They probably aren't doing a thing, if they even exist."

Harry slipped on his clean, too large clothes, and started downstairs to make breakfast for the Dursleys.

After making a whole family meal, and finishing his portion, he left the house. His new habit was to wander the streets in the small town nearby. Making it there was easy enough; it just took a little while.

Harry sat down on a bench to rest. He had been walking around for hours, trying and failing to find something else to do.

Then, there was a crash. A loud, bang.

A nearby wall exploded.

Harry watched wide eyed at the uncommon sight. What had happened?

Then out of the smoke and rubble, something moved. Something very large. As Harry started to see the outline of the creature, he began to think that it was a dragon. He stumbled backwards, off of the bench.

"Shit."

The smoke cleared a bit more, and Harry saw that it wasn't a dragon. Harry, in all actuality, had no idea what it was. But it was ugly as sin.

It was a giant humanoid type creature, with red and black skin that looked distinctly like scales, and had a large white mask over its face. Its eyes glowed red. If that hadn't convinced Harry that it was evil, the fact that it held a small girl in its hands would have.

Harry drew out his wand with a snarl. "Why does this always happen to me?"

He raised his wand, and swirled it around in a circle. "Litis." The battering hex did its job, and stuck the wrist of the hand holding the girl. The demon let go, and hissed at Harry.

Harry dashed forward, grabbing the girl, and running away as quickly as possible. This apparently, wasn't quite quick enough, as the thing appeared in front of Harry a second later.

"Shit!"

The monster brought up one of its large grotesque hands, and swung down at Harry. He held on tightly to the girl, and jumped back as far as he could. The hand smashed down where he had been a second ago, and left a giant print on the concrete ground.

Harry turned and started to run again, holding the small girl to his chest. "Let's get outta here, alright?" he whispered to her. She nodded silently.

There was another huge crash as the hand landed a few feet behind him. Harry stumbled, and both him and the girl fell to the ground.

They rolled over, and stared at the beast looming over them. It raised its hand again, ready to crush them both.

Everything seemed to slow down to Harry.

Lower…

Lower…

Closer and closer the hand came.

Then Harry noticed something odd. The silhouette of a butterfly had appeared between the hand and Harry. Harry focused on it, and it changed into the shape of a girl, wearing loose black clothes, somewhat like robes. A sword was hanging at her side, which she pulled out to attack the creature with.

In one slash of the sword, the hand of the creature was split. The girl pushed off the ground, and brought up her sword. And as she came down, she split the creature completely in half, making it disintegrate. Harry stared, wide eyed.

The girl looked over her shoulder at Harry and the girl, and then walked away.

"Wa-wait!" Harry shouted.

The girl just vanished around a corner.

Harry set the girl down, noticing for the first time he had been holding a ghost. She had one of the broken chains coming from her heart like the ones that he had seen at Hogwarts.

"You should really get moving on to the next world if you don't want something like that happening again." He said to her.

She nodded. "Thanks for saving me, mister!"

"No problem. But you should thank that other girl if you ever see her again. She saved both of us." Harry turned and started to walk back home. The girl vanished back into thin air.

Dusk, that Day…

Harry was lying on his bed, still thinking about the events earlier that day. He had spent hours looking through all of his defense books for any sort of creature that had a vague resemblance to that thing he had seen earlier, but had found nothing. Nothing!

And that girl, she became a butterfly. Was she a witch, an animagus? Or was she something else entirely? Harry hadn't seen a wand on her, but her clothes had been baggy enough to conceal one easily. But she had cleaved the creature in half using a sword!

Damn it, I'm getting no where. There's no information on stuff like this in any of my books. Harry snarled.

Then, the vision of the butterfly came back, floating in front of his face. His eyes widened.

Following the butterfly with his eyes, it came to the wall. It simply landed, and the wall started to fade away to blackness.

Out of the blackness stepped the girl from earlier. Harry got a closer look at her this time.

She wore Japanese styled clothes, a hakama and a kimono, all in black, with a white sash at her waist. The sword held in her sash had a square hand guard with the corners cut off, with two comma holes carved into it.

Her hair was short and black, with several spikes sticking down out in the back. One long bang sat directly between her two large purple eyes.

On her feet were white socks, and small thin sandals.

"Who are you?" he whispered.

She just looked around the room. Harry pulled out his wand.

"Who are you?" he asked, louder. She continued to ignore him. Her hand left her side to grip the sword at her waist.

Harry twitched.

Then her voice sounded. "It's close."

Harry stood up, walked directly in front of her line of sight, and put his wand right between her eyes. "Look, lady, I have no idea who you are. You can't just come barging into my room, then ignore me when I ask who you are. Now spill!"

Her eyes widened. "You can see me? And your stick, it's touching me!"

Harry rolled his eyes. "Of course I can see you, I've only been asking your name for last minute and a half. And yes, my wand can generally touch people. That's not so surprising, is it?"

She raised an eyebrow. "You… you were the one in the town earlier today. You were helping that ghost girl."

Harry snarled. "You just noticed!"

"You shouldn't be able to see me. Or those other ghosts. But you can see me, and touch them, since I saw you carrying her."

"So what? I can touch them, and I can see you. Why shouldn't I be able to?" Harry asked, genuinely interested.

She turned around, and looked back over her shoulder. "I am a Shinigami."

Harry just stared at her. "Okay… and that means what?"

One Long Explanation later…

"Okay, so you're a Shinigami." She nodded.

"And you come from a place called Soul Society." She nodded again.

"And your job is to vanquish evil spirits." She nodded a third time.

"So that means what I saw in town was an evil spirit?" She nodded a fourth time.

"And that evil spirit was trying to take the spirit of that little girl." And she nodded for the last time.

"Okay. I'll believe you for now. It makes sense, I suppose. You said that you Shinigami have a type of magic, correct?"

"Yes. Do you want a demonstration?" she asked.

'Sure." He nodded, excited.

"Bakudō no Ichi: Sai!" She stabbed two fingers into his stomach, and then pulled them back.

Harry snarled as his arms were pulled behind his back. His whole body tensed up, and froze as if it were under a full-body bind. Harry fell to the ground, face first.

"Okay, that's just a bit irritating. I think I can get out of this, just give me a minute." Harry said, hissing at the pain in his face.

"I wouldn't recommend it. That is high level Kidō, magic that only Shinigami can use. It's unbreakable to humans." She responded.

"Uh, sure. If you say so. I'll just sit here, trapped on the floor, being unable to move. Yeah, right." Harry snarled sarcastically. "At least my lungs didn't seize up; I'd rather not die from lack of breath. It'd be embarrassing."

The Shinigami let out a giggle. Then, her cold façade came back. She drew out her sword. "That ghost in the corner. How long has he been haunting this room?"

"Not sure. I've only been able to see ghosts since school ended this year. He's been here the entire time though. I'm guessing he's been in the room for a while, I just never noticed. Why?"

"It is one of a Shinigami's duties to send the spirits of the dead to Soul Society." She turned to the ghost, a man appearing to be in his late fifties. "Do not worry. Soul Society is a good place." The man nodded.

She placed the end of the hilt of her sword on the man's forehead, leaving a glowing blue mark there. The man started to glow, brightly, before sliding through the floor. Before leaving, he put his hands into a gesture of prayer.

"So, he got sent to that Soul Society place, huh?" The Shinigami nodded.

"He was a plus soul, so yes, he did get sent to Soul Society."

"A Plus soul?" Harry asked, inquisitively.

"There are two types of souls in the world. Allow me to demonstrate." She reached into the front of her kimono, and grabbed a small sketch book. After a few moments of drawing, she put a picture in front of Harry's face.

On one side, a cartoon bunny face was there surrounded by hearts of all shapes and sizes. The words "Plus, Good Spirit" stood out prominently.

"The good souls are called Pluses, they are the souls that you normally see around."

On the other side, there was an angry cartoon bear, surrounded by what looked like bolts of lightning. The background was black. The words "Hollow, bad spirit," were displayed prominently.

"The other type is what we Shinigami call hollows. They attack the living and the dead to try and steal their souls."

"Any questions?" she looked at Harry.

He just sat on his front, still bound by the spell, sniggering.

"What's so funny?"

He just burst out laughing. "Your… your drawings! They're terrible!" For another minute or so he couldn't form words because he was laughing so hard.

She stood, and walked over to his prone body.

…

WHAM!

…

"Ouch! Jeez, what was that for?"

"Back to the explanation. We Shinigami have two main duties." Here she held out another drawing. It had a bunny with an arrow pointing to a large flowery shape with Soul Society written in the middle. "The first is what you just witnessed. We use the soul burial technique, Konsoh, to send the Pluses to Soul Society. The second…" here she held out a third drawing. It had a bear right in the center, surrounded by cartoon explosion marks, and with a large "Kapow!" written at the top, "is to kill hollows and vaporize them." She drew a large 'X' over the bear.

"But why was the hollow after the girl?" Harry asked.

"I'm afraid I don't know. She doesn't seem to be anything special. We have yet to understand the full habits of the hollows."

Suddenly, a shiver ran down Harry's back. A loud screech filled his ears.

"Hey, did you hear that?"

She ignored his question and continued on speaking. "In any case, there is a second one around here somewhere."

Harry snarled. "Then why don't you go after it?"

"I have been… unable to sense it's presence for some time now. Something else is obscuring it."

"What are you talking about? Can't you hear that screeching noise? What else could it be?" Harry hissed.

"What loud scree-"

A screech filled the air. The Shinigami's eyes widened.

"That was the cry of a hollow!" she cried.

"I told you!" Harry shouted.

A human scream rent the air. Harry's eyes widened. "Aunt Petunia!" he cried out. She may have beaten him, and many other things, but she still was his only family. He didn't want her to die.

The Shinigami stood and rushed out of the room. "Hey, wait!" he cried after her.

"Harry! Harry, you've got to help mum!" came a voice from the hallway. Harry's eyes widened. Dudley was asking for help? From him?

"Dudley!" he shouted, as the fat boy collapsed on the ground in front of the doorway. After checking to see if he was still alive, the Shinigami ran downstairs, towards the screams. "Wait!" Harry shouted again.

Harry snarled: this was not his day. Twice, he'd run into these strange… hollows.

"Fuck it." He hissed. His muscles screamed at him, but he started to force himself to stand up.

He made it to the end of the hallway, before tripping and falling down the stairs. At the doorway of the house, looking out into the street was the Shinigami, holding her sword.

"Aunt Petunia," he hissed, putting all his effort into standing up again. He stumbled in front of the Shinigami.

She snarled at him. "Get out of the way. You'll just get hurt."

He snapped at her, "Shut up!" before his eyes focused on what was in front of him. There was Aunt Petunia, held in the grasp of a monster that looked similar to the one that he had seen earlier.

"Damn it." Harry took a deep breath.

Then he started to pull magic from deep inside of him. He tried to pull his arms apart.

"Don't! No human strength can break the Kidō! It's not possible!"

The air around Harry started to deform. It changed to blackness, and symbols started to appear in the air.

The Shinigami's eyes widened. A golden glow started to form from Harry's body. "What…"

The seals surrounding Harry started to fade away. Only the ones right next to his body stayed still.

Harry growled. Then he pulled more magic, and more and more and more, until he had enough to counter the spell that held him in place.

Finally, he roared. "Finite Incantatum!" thrusting all of his gathered magic into the Kidō spell.

With that cry, the spell around Harry shattered into dust.

Harry snatched his wand out of his pocket, and charged forward. Lashing out with the wand, he cast another super powered spell, "Ventus Vesica!" A long blade of green energy sprouted from his wand, cutting off the hand of the hollow, the one that held his aunt.

The Shinigami's eyes got even wider. The boy could use some kind of magic!

Harry waved his wand in a circle, and then jerked it back. "Accio Aunt Petunia!" he called, causing her to come flying to him.

The hollow looked over at Harry. "I've found you…" it screeched. It raised its hand, and attempted to smash Harry with it. Harry jumped forward, dodging the hand, barely.

Then, in an instant, the Shinigami struck the hand that was buried in the ground. She flipped over the hand, which the hollow pulled out with a scream. The hollow vanished into the blackness.

Harry shook his aunt. "Hey, Aunt Petunia, you alright?"

She didn't respond.

The Shinigami did, though. "Stay calm. She has not lost her soul just yet. I can still sense it. That is strange, but it appears the hollow is looking for a more spiritually dense soul. It makes sense now at least."

Harry stared at her. "What do you…?"

"That hollow from noon today wasn't after that little girl."

Harry's eyes widened.

"But…"

The Shinigami looked over her shoulder at Harry. "I don't know why, but until now, your spirit power has been locked up tightly. I was only able to sense a tiny amount, and that's why the hollows have never attacked you before. The only thing I can think of is that when you touched that ghost today, the spirit energy that was sealed away was released."

"In other words, those two hollows could tell you had a spiritually dense soul just by you touching that little ghost girl." she continued.

"They are all after you!"

Harry stared at her. "After… me?"

Nearby, the hollow started to reform "It's back, stay away." The Shinigami shouted.

Harry started to snarl again. "Oh shut up. Everything that's happened so far has been my fault."

"What are you…?"

"It's my fault that my family, the only family I have left, is getting hurt!"

"I'll deal with this myself." He snarled, raising his wand. He raised his voice. "Hey, bastard! You want my soul, right? Come take it from my cold dead body then!"

The hollow screeched, and charged much faster than something its size had a right to do.

It was beared down on Harry, and he was frozen.

Then, in a flash, it was over.

In front of Harry stood the Shinigami. The Hollow had bitten her, right on the shoulder, and she was dripping large amounts of blood. The hollow let her go, and she fell to her knees, blood spraying out of her wounds.

Then she fell forward, onto her face.

"Shinigami!" Harry shouted.

Her voice was soft, but she replied. "Idiot. You couldn't have fought it off, not without dying in the process. You should have known that."

Harry stared at her. "Or did you think it would be over if you gave it your soul?" She laughed a bitter laugh.

"At this rate, we'll all become its food." In the background, the hollow screeched in pain. The Shinigami had struck it in the mouth when it had bitten her.

The Shinigami crawled over to the wall near her and leaned up against it. "Do you want to save your family?"

Harry narrowed his eyes. "Of course I do, is there a way?"

"There is. You must become a Shinigami yourself."

Harry jerked back, as if struck.

"Place the point of this Zanpakutō over your heart, and I will attempt to transfer my powers into you."

The hollow screeched again, before it started to lumber closer.

"I know not if it will work, but we must try. There is no other way."

Harry nodded, his eyes resolute. "Let's do it then, Shinigami."

"My name isn't Shinigami. My name is Rukia Kuchiki."

The hollow started to charge for them.

"And I am Harry Potter." He spoke, as he gripped onto the blade.

The blade pierced Harry's heart.

Silence spread in that moment.

Light started to come from deep within him.

It shone almost as bright as the sun, illuminating everything around them.

The hollow froze in place.

Then, the light vanished.

The hollow's arm that was raised for attack was instantly cleaved off.

Harry stood on the other side of the hollow, a katana larger than him in hand, wearing the black clothes of a Shinigami.

Harry hissed at his sword. "Way too unwieldy." He concentrated his magic into the blade, and then jerked it back.

The blade shrunk to the size of a slightly smaller than usual katana.

"Let's go, hollow bastard!"

The hollow spun around, and swung the stump of the first arm back at Harry. He just raised the sword, and jumped up, landing on the arm. He jumped again, in front of the mask of the creature.

"Now die for the pain you've caused my family." He raised the sword, and stuck the right down the center of the mask, cleaving it in two. The hollow dissolved into nothing.

"And that's that."

- - - - -

And Harry decided; life would become quite interesting after that day.

- - - - -

A/N: Yes, I know this almost exactly word for word from the first episode, but the set up in the start was mostly the same. It'll deviate later.
