AN: I got addicted to Bleach and watched all the available episodes. This idea just popped into my head and I had to write it down and post it here on . I hope you'll like it. So this is a Harry Potter/Bleach crossover.

Disclaimer: I don't own Harry potter or Bleach.

The dream

"Onii-chan, onii-chan, where are you?" A young boy coughed.

Smoke and fire was all around him. He couldn't see a thing. Where was his brother? They had been together when all of this started. A fire had broke out in the house they lived in and the two young boys got separated when the house started to collapse.

The two boys were twins and had never before been separated. The one who had called for his brother before was named Yuki and his brother's name was Toshiro.

The boy fell on his knees, coughing as the smoke irritated his airway. The heat was getting to him too and it didn't take long before he collapsed.

The scene changed. The same boy was now in a run-down neighborhood. Flashes of his life their passed by. Then it stopped to show another scene in more detail.

A man with brown hair and wearing glasses walked up to the little boy. Another man, this one with silver hair and a fox smile plastered on his face, was following him. The little boy looked wary. The two men were garbed as shinigami and the one with the glasses had a white haori, stating he was a captain.

"Tell me boy, what is your name?" Captain four-eyes asked.

"Y Yuki." The boy stuttered.

"Are you scared, little one?" Fox face asked.

The boy shook his head.

"You got quite some power, don't you? You hear a voice, isn't it?" Captain four-eyes asked.

"H how, how do you know?" Yuki asked.

"It is easy to sense someone who is fit to be a shinigami. The voice you hear is that of your Zanpakuto. Being able to hear your Zanpakuto at such a young age is quite formidable. You must be very strong." Captain four-eyes answered.

"St strong? M me?" Yuki stuttered.

"You should enter the Shinigami Academy." Captain four-eyes suggested.

The scene changed again. This time showing the boys time at the academy. The scenes slowed down again when the boy had graduated.

"The boy is a genius. Finished in just a year."

"They told me it was Aizen-taicho who had found him."

More rumors spread to all of Seireitei as the boy walked to the barracks of his new home, the barracks of squad 5.

"So, you graduated in one year. I knew you were strong, but I never knew you were a genius." Fox-face aka Ichimaru Gin said when the boy entered the office.

"Congratulations and welcome to squad 5." Aizen-taicho said.

The scene changed again, showing the boy becoming vice-captain. Then it flashed to another scene.

'Remember'

The boy was send to the real world for a mission. Aizen suddenly appeared on the scene.

"Aizen-Taicho, what are you doing here?" Yuki asked suspicious.

"You've been a great help to me, Yuki." Aizen said with a smile on his face.

"What are you getting at?" Yuki wondered.

Aizen raised his Zanpakuto.

"You know too much." Aizen said.

'Remember my name'

Yuki grabbed his own Zanpakuto and blocked the trust of Aizen's only to find out a few seconds later that Aizen had already released his Zanpakuto.

Blackness filled his sight as everything faded to darkness.

'You have to remember, he will try to finish what you tried to prevent'

Whose voice was that anyway.

'Remember'

With that last word one Harry James Potter woke up from this bizarre dream. For once he didn't wake up from his usual nightmares he received due to the connection he had with Voldemort.

"Ok, that was the weirdest dream I ever had. I wonder what that voice at the end wanted me to remember." Harry wondered as he started to prepare for another day of torture at the Dursleys household.

Harry had already mostly forgotten about the dream by the time he was finished with all the chores he had to do for the day. The sun had already gone down and Harry was about to go back inside when he heard an animalistic howl.

"What the hell was that?" Harry wondered out loud.

He ran to the place he heard the sound coming from. He didn't had to run far. He had only ran to the corner of Privet Drive when something huge came from around the corner. He didn't exactly know what it was, only that it was huge and ugly.

Most of its body was covered in a greenish fur. Its long tail was swishing around like a whip and it had a white skull like mask covering its face.

It seemed like the creature was snuffing the air, obviously searching for something. What Harry found weird was that no one seemed to noticed that a huge monster was taking a stroll in their street. There were people outside, but they were just minding their own business. It was as if they couldn't see or hear it.

"I found you." The creature suddenly spoke as its attention was now totally on him.

Harry was perplex that such an ugly creature was able to talk. Harry took a hold on his wand and took a step back.

"Where're you going? Don't think I will let my dinner escape." It said.

"Dinner?" Harry asked perplex.

"You've got a tasty soul, give me your soul." The creature roared, before it launched at Harry.

"Protego." Harry shouted as he took out his wand completely.

The monster was stopped by the shield charm, but it cracked immediately on impact. Harry fastly tried to find a way out, but was not fast enough when the monster smacked him down with one of his huge arms.

"You're not going to get away. Your puny trick won't work with me." It said.

It was right. Harry's shield was broken immediately, the monster was that strong. Harry stood up again. His arm was sore from the hit.

"Reducto." Harry shouted.

The spell caused an explosion on impact, but when the smoke cleared it was obvious it had also no effect.

"Stop your resistance, it's useless." The monster laughed.

The monster was about to slam him again, but suddenly its arm fell down as if it was separated from its body. When Harry looked closer it indeed was what had happened.

A girl had appeared in the street. She was garbed in loose black clothing, similar to that of Japanese samurai's. A katana was in her hand and it was dripping blood.

Obviously it was the girl who had severed the monsters arm. The girl turned back to the monster, jumping up to slash down at the creatures head. The monster wasn't given any time to counter as a few minutes later it disintegrated.

The girl took a glance in Harry's direction, before she ran off.

"Wait, who are you? What was that?" Harry shouted, but the girl was already gone.
