Hi, everyone. This is a Bleach/Harry Potter crossover. There are a few things you should know before reading it.

1. As I'm writing this, I have the first Harry Potter book next to me (literally, I'm not lying) and I'm using it for research (because people take these things seriously *cough* sarcasm *cough*).

2. This is set (for Bleach) after Aizen is defeated. For Harry Potter, the first book. So, no spoilers after, but there may be spoilers for things leading up to these points. You have been warned.

Disclaimer: All credit goes to Tite Kubo and J.K. Rowling. Seriously, those two are awesome!

In Soul Society

It was a typical summer day in Soul Society. The birds were singing, the clear sky was a deep blue, and the sun was shining. Everything was peaceful; Shinigami were doing their duties, and for once there were no immediate enemies or battles to fight. All was peaceful.

Despite all that, Hitsugaya Toshiro was miserable.

The sun was shining. That miserable, awful, cruel ball of fire sneering down at him. How he wanted to freeze it over. It would make him quite a bit happier and feeling less like he was melting.

It was on days like this when the temperatures climbed into triple digits that his squad started actively avoiding him. They all knew how grumpy and irritable he grew in the heat, so they decided that the best course of action would be to simply not be around him. He found it a mixture of amusing and annoying. After all, he was their Captain. They couldn't avoid him forever. That didn't stop them from trying.

And so, on these miserably hot days, Toshiro found that there were only a few ways to deal with the heat. 1. Try to ignore it. 2. Stay home and try not to disembowel or otherwise harm anyone. 3. Freeze whatever room he was in and hope for the best.

Right now, he chose the third option.

On this hot day, he was sitting in his office as usual, doing paperwork like usual, yelled at his Vice-Captain like usual, and was in Shikai. Not usual. The considerably smaller and less destructive ice dragon was curled around the edges of the office, and most of the room was covered in a thin layer of ice. The only exceptions were the desks, chairs, couches, doors, and a path on the floor leading to the desks and out the door. Perfect.

The first few times he had done this, people had flocked to his office to enjoy the cold. He soon grew tired of this and steadily lowered the the temperature until it was far below freezing and they had to flee unless they wanted frostbite. The only ones he allowed to stay were Rangiku Matsumoto, Rukia Kuchiki, and work related people. He only allowed Rukia because he knew that she did as well in the heat as well as he did. Which was, to say, terrible.

He also became very reluctant to leave the office, as the heat would hit him like a speeding train, and so was understandably irritated when a Hell Butterfly fluttered in, chiming happily. He narrowed his eyes, and Hyourinmaru lifted his large icy head in response to his thoughts. "Shall I destroy it, master?" he asked.

"No," Toshiro silently sighed, and lifted a hand for it to land on. "Maybe I won't have to get up."

"Captain Hitsugaya Toshiro of the Tenth Division is to report to Head-Captain Yamamoto's office immediately."

The butterfly took off, as if aware of his sudden desire to kill.

With a sigh, Toshiro stood and strapped his sword to his back, returning it to it's sealed form as he did so. Luckily the ice would remain for some time. Deciding to get it over with as fast as he could, he shunpoed to the first, and knocked on the door before being called in. He bowed briefly before the desk and the Head-Captain. "You called me," he said politely.

"Yes, I did. Thank you for coming. I know how much you dislike the heat." His voice held some sympathy, and Toshiro suddenly wondered if the Head-Captain didn't like winter. If so, that was sad. Incredibly sad.

"It is nothing, sir."

"Yes. I have a mission for you. Here is the file." Toshiro stepped forward and accepted the thick file. "It will be long. You are to go to the world of the living; England, specifically, to a school of magic."

Toshiro lifted one white eyebrow. "Magic, sir?" He couldn't hold back the disbelief in his voice.

"Yes." The Head-Captain nodded. "The local Shinigami witnessed a mortal casting what he could only describe as a 'spell.' Your mission is to find out whether or not these wizards are a threat to us or not."

"Yes, sir." Toshiro said this, but his tone made it clear that he had an opinion, but was unsure whether or not to voice it. Head-Captain Yamamoto picked up on it.

"What is it?"

"How is it that we haven't noticed these wizards before?"

"The wizarding community is very good at keeping their existence a secret. Apparently not even the normal humans are aware of them."

"Sir."

"One more thing." At this, Yamamoto made sure he had eye contact. "This mission will span the entire school year."

"A year!" Toshiro's first thought was an image of his office literally overflowing with the uncompleted paperwork Rangiku undoubtedly wouldn't do. "But sir, why-"

"There is no better way to learn about a society than to attend its school. Thus, you will pose as a transfer student from Japan. However, you can come back for holidays."

"Yes, sir. When do I leave?"

Just as he said this, a brown owl flew in, circling Toshiro and dropping its letter at his feet before flying away. Curious, Toshiro picked it up and discovered that it was a thick envelope of yellowish parchment, and words written in emerald green ink. It took him a moment to adjust, as they were written in English.

Mr. T. Hitsugaya

First Division

Office

Seiretei

Soul Society

Toshiro frowned, more than slightly uncomfortable with how accurate the address was. He glanced up at the Head-Captain, who said, "That is from the wizard school. You are to leave tomorrow morning at eight am from the main Senkaimon. The details are in your mission folder. Read them today."

"Yes, sir." He shifted the folder and envelope to his left hand, and bowed. "If that is all, then I shall go and start reading."

"That is all. Good luck."

"Thank you." With that, Toshiro left.

As soon as her Captain left, Matsumoto called in all her drinking friends, and they rushed over to enjoy a cold room and some sake. They were just getting into the swing of things when the door slid open, and a loud, angry voice yelled, "GET OUT!"

The traitors left her to face the fury of her Captain alone. She stood, swaying a little, and squashed him in a hug. "How was the meeting, Captain?" she asked, trying to distract him. Once he fought free, he glared at her.

"Just because I leave to the meeting does not mean I won't be coming back. Don't host sake parties in here."

"Yes, Captain," she sighed, then caught sight of the papers in his hand. "What are those? You got sent on a mission?"

"Yes," he said grumpily, making his way over to his desk. "It lasts for a year, so no parties, and do your work while I'm gone! You'll be the one running the division and I won't be around to do the paperwork."

"Oh!" She slumped down onto the couch, peering over the back with a depressed expression. "But Captain-"

"There's nothing I can do about it, so shut up!"

She groaned and flopped back with a flamboyant sigh.

Toshiro opened the envelope first and read the letter.

Toshiro's first thought was: Who would want a toad?

The next day, at eight am, Toshiro was standing in front of the Senkaimon wearing a gigai, human clothes, and with a trunk and Rangiku. She said she wanted to see him off, but he knew she just wanted to give him another terrifying hug. And so she did.

After pulling away, he gave her a stern look. "Do your paperwork while I'm gone."

She rolled her eyes and made a dismissive gesture. "Yeah, sure. Try to make some friends while you're there, and have fun!"

He gave her a glare, but she ignored it. "Matsumoto..."

She turned to him and had a strange expression on her face. "Be careful Captain, all right?"

Caught off guard, he nodded. "Of course. You too."

She nodded and waved while he walked into the Senkaimon. As soon as he disappeared, Rangiku turned and triumphantly whispered, "Sake party!"

So, what did you think? Please let me know.
