Summary: When Voldemort's return creates a problem for both worlds, Hitsugaya is sent to deal with the problem. Hitsugaya, now a first year student, must follow the fifth year Potter boy, find the dark lord and kill him before things get out of hand.

Time line: Fifth book and sometime after Aizen's betrayal.

Notes: My first crossover, hope you like it . Taichou means captain, soutaichou means captain-commander. I'm using the English words in this chapter, since they are in England and trying to make things easy for Dumbledore to understand.

Also, I will use OCs in this story, but they will NOT have significant parts.

Warnings: Aside from my spelling errors, there shouldn't be anything.

Disclaimer: I do not own Harry Potter or Bleach. Harry Potter is the creation of J.K. Rowling and Bleach is the creation of Tite Kubo. I am writing this fanfic for entertainment only and am not making any money with this fic.

Chapter One

The room bathed in a red light that flooded in from the open window. It warmed the old man, whose face showed the strain of the years he had lived. This day had been as tiring as many before it, maybe even more so. A soft sigh escaped the man as he put down a parchment. It seemed that this year the task would be impossible even for him.

Giving up, the old man leaned back in his chair, set down his glasses, closed his eyes and stroked his beard. He couldn't help it, this case he would just have to give to the ministry this year. This could prove to be a major setback in his plans.

"Albus Dumbledore, I presume?" With a start the old man drew a thin piece of wood from the pocket of the robes he wore, pointing straight to a man that had most certainly not been there a minute ago. The said man was on his knee, bowing respectfully. The older man regarded the young one for a moment before lowering his wand and relaxing slightly.

"That is correct."

"I am Kentaro, fifth seat of the second division of soul society. I have come here on the behalf of captain-commander Yamamoto. He wishes to speak with you." Dumbledore regarded the man carefully. He wore foreign set of clothes, the kind Dumbledore had always connected with Japanese history and samurai tales. He was young and obviously talented (if the rank wasn't enough proof, the way he had entered his office so silently spoke volumes). The sword that the young man had did not go unnoticed either.

"I have not heard of Soul Society nor of Yamamoto. What reason do I have to trust you, a complete stranger, especially in these dangerous times?" The young man named Kentaro flinched a little.

"I understand your concerns, yet I am not in the position to disclose the information that you seek. But I assure that if you'll speak with Yamamoto-sou-taic— I mean the captain-commander, your question will be answered." Dumbledore regarded the young man for a while longer.

"Fine. I will meet this Yamamoto. When does he wish to see me? I must say that my calendar is rather full. After all, the school year is starting soon."

"Do you have time right now? Captain-commander is also a very busy man and he wished for me to inform of your decision as soon as possible." Dumbledore raised an eyebrow.

"Well certainly… by what means?"

"This will take only a short moment." And Kentaro shut the window, pulled the curtains tight and took and strange device from his back pack. He put it against the wall and Dumbledore watched in silent awe as the device sprouted roots and grew greater and greater. Soon it covered the entire wall, roots digging deeply in its smooth surface. In the middle was what a muggle would call a TV-screen. It flickered to life and Dumbledore was staring at a face more ancient than his own. Kentaro moved aside and bowed respectfully. "This is the man, Yamamoto-sou-taichou." Dumbledore bowed.

"I am Albus Dumbledore, headmaster of Hogwarts. It is nice to make your acquaintance"

"I am Yamamoto, Captain-Commander of Soul Society." The ancient man nodded in acknowledgement, and when their eyes met, Dumbledore felt like the eyes could see right through him. This unsettled him greatly, after all, he had heard that he himself had that effect usually and just now realized uncomfortable it was to be the object of such gaze.

"During this meeting I shall tell you things that must stay a secret. The words you hear here today must be carried with you to your grave. This I must ask of you, since usually sharing this information with a mortal is forbidden." Dumbledore stayed quiet and weighted his options.

He could ask the man to tell what this was all about before he gave his answer, but he doubted that he'd be granted with an answer. It'd probably just anger the Captain-Commander. He could of course say that he couldn't promise before he heard what this was all about. This would have the same outcome as the former solution. It seemed he had no choice but to accept. Not that he minded that much, he had already grown curious. One thing the man had said bothered him though…

"Information that it forbidden from mortals, you say? You must know what such words make a mere mortal man think…"

"Such matters will be explained if you choose to accept."

"Fine then. I shall accept your conditions. But I'm afraid that making an unbreakable vow or an oath of secrecy with you through this… device is impossible." The Captain-Commander nodded, the corner of his lips rising just a bit.

"For now I will trust your word. Kentaro-kun can make such vows with you later."

"Hai, Yamamoto-sou-taichou!"

"So, I must say I am rather curious about this…" Dumbledore raised his hands to indicate Kentaro and the TV-device had taken over his wall.

"Let me start with a summary of our existence, but I cannot go to details. As you may have already realized from the name, Soul Society, all of us are indeed dead. We are shinigami, death reaper might be a more familiar term for you. Soul Society is the place that plus souls go to, after being sent from the real world by a shinigami."

"Plus souls?"

"Souls that haven't been touched by evil, you could say…" Kentaro said, it was obvious to Dumbledore that Kentaro didn't tell the whole truth, but decided that pursuing the matter was not wise for the time being. Yamamoto nodded.

"I see… please, do go on."

"The real world and Soul Society depend on each other. Neither can exist without the other and changes in other affect the other as well. Now to the real issue at hand. I take that you know a young man by the name of Cedric Diggory?"

Dumbledore was more than surprised to hear the name but nodded all the same. "Yes, he was a student of this school. A fine young man who passed away this June…" Yamamoto nodded.

"In Soul Society, we keep the records of everyone that has died in your world and arrived in ours. In Diggory's files we discovered something that really concerned us. The cause of his death was similar to many of others some fifteen years ago." Yamamoto's shoulders seemed to have sagged a little, making the already old man seem even more so. Dumbledore let out a sigh and let his own weariness show.

"Yes, Lord Voldemort has come back I'm afraid. He was revived from his ghost like state last June, the very same day he killed Cedric with the killing curse, avada kedavra."

"We talked to Diggory and heard that there is a boy in your school that has caught Voldemort's attention and that he is most likely trying to kill the boy."

"The boy's name is Harry Potter. And indeed he is a pupil of this school. But you say you talked to Cedric? How is he?" Yamamoto didn't seem pleased with the question and stayed quiet for a long time. Finally he let out a sigh.

"Dumbledore-san, I understand your feelings but there are things that I cannot tell you for it'd break our laws. This conversation that we have had so far has already broken most of them." Dumbledore lowered his gaze and nodded.

"I understand. I apologize for asking such a question." Dumbledore raised his eyes to meet the older mans. "Please continue." Yamamoto cleared his throat and Dumbledore noticed something: someone had just moved in the dark background of the screen.

"Yes, let us continue. The shinigami who have been positioned in England have reported that deaths by the killing curse have started to appear once more. A death by killing curse is very tiring and troublesome for us shinigami, for sending such a soul requires a special soul burial that only highly ranked shinigami can perform. Normally we wouldn't be as bothered but a war is coming up and we do not have enough man power to take care matters on your end. "

"But you must have a solution since you have contacted me." Yamamoto nodded and looked behind him. And like Dumbledore had suspected, there was another person with the Captain-Commander, a young boy with snow white hair and large teal eyes. The boy bowed deeply.

"This is Hitsugaya Toushirou, tenth-division captain."

"It is nice to meet you, Hitsugaya Toushirou. My name is Albus Dumbledore."

"Nice to meet you Dumbledore-san." The boy's voice didn't suit his young appearances, Dumbledore decided. Yet if the boy really was dead, then who knew how old he really was?

"Hitsugaya here has the before mentioned abilities, so I will be sending him to England to deal with the problem. However, he is a captain and therefore an important part of our military. We would like to have this over and dealt with before the war starts. I would like you to enroll him in your school so he can be near this Potter boy. This way it'll be easier for him to find this Voldemort and dispose of him."

"I see… We could use an ally at the present moment, since it seems that it'll be a three-way war for now. Harry will be attending fifth year… But I doubt that anyone would believe Hitsugaya to be fifteen years old. He could pass for a first year though." Dumbledore was sure that he'd seen the boy twitch when he said this. Dumbledore couldn't help the small smile that crept on his lips.

"It won't matter. Just to have him in the school will be enough. I have great trust in Hitsugaya-taichou. I think this will be enough for today. Hitsugaya-taichou will arrive there in two days of time. You may ask more of the mission from him upon his arrival."

"May I suggest something? It might not be a good idea for me to meet him in the open or someone might start suspecting that something is going on. I am quite hated at the moment you see, and I am also being shadowed almost where ever I go." Yamamoto raised his eyebrows.

"I understand. What do you suggest?"

"I shall send a colleague of mine to meet with Hitsugaya in The Leaky Cauldron that is situated in London. I shall tell him that Hitsugaya is a new, muggle born student who needs help with getting his school supplies. This way he'll get more information on the magical world and we can talk safely after the school year has started."

"Yes, it sounds agreeable. Do you consent, Hitsugaya-taichou?" The white haired boy nodded.

"Yes."

"It's decided then! I'll give Kentaro here the admittance letter; he can surely deliver it to Hitsugaya?" Dumbledore was smiling.

"Yes sir!" Kentaro replied

"Do you have money, or do you require the school's help?" Now Yamamoto laughed a short amused laugh.

"Do not worry, we will manage that part ourselves!" Dumbledore nodded. "It has been nice talking to you Dumbledore, I hope your war shall end soon, for both of our sakes."

"Thank you. I hope you will be victorious in yours, when the time comes." Yamamoto nodded and the screen flickered once before it turned to black. Dumbledore stared at the empty screen for a while before turning to Kentaro. "I take it that now would be time to make the oath of secrecy?"

"Yes, you are quite right." Kentaro rose from his kneeled position and watched amazed as the wizard literally drew a chair with the thin wand he had had in his hand the whole time. Dumbledore motioned for Kentaro to sit and then took his own place behind his table.

"Before we start, would you like a cup of tea and a sherbet lemon?"
