First chapter of the rewrite. :) I'll be fixing up a lot of inconsistencies from within the first one, as have been repeatedly pointed out. Also, longer chapters and overall better writing (probably).

I don't own Bleach or Harry Potter, which belong to their respective creators.

"Hitsugaya!" A male voice screeched as he burst into room, stumbling to a stop. Panting, Izukai Shouta moved with a purpose and grace found only with years of practice towards the desk of the Tenth Division Captain. He threw the thin objects in his hand onto the top of the furniture before stumbling over to the nearby couch, collapsing atop it.

He ran a hand through unkempt brown hair, letting his bare feet dangle over one edge of the couch as he closed emerald green eyes. He let out a sigh, scratching his stomach from underneath a blue yukata.

"I'm guessing this letter is important?" One Hitsugaya Toshiro asked, raising an eyebrow at the dirty feet only inches from the couch he just had cleaned. When he didn't get an answer, the snowy-haired Captain sighed and shook his head, setting the paperwork he was currently working on aside. He stared at the strange and undoubtedly foreign address on the letter, turning it over to inspect the seal briefly before opening it.

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: ALBUS DUMBLEDORE

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. of Wizards)

Dear Toshiro Hitsugaya,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on September 1. We await your owl by no later than July 31.

Yours sincerely,

As he stared at the vaguely familiar English letters, the temperature dropped steadily. The brunette on the couch sat up abruptly, shivering and staring at the white-knuckled grip of the figure seated behind the desk. Turquoise eyes snapped up to meet emerald green, glaring with unbidden annoyance as he flicked his wrist, the letter landing in the trash. The brunette drew his legs up to his chest as frost began to form along the floor.

"Izukai," he growled, "What is the meaning of this?" The teen jumped at his name, raising his hands.

"Hey, hey! Don't look at me. I've done a lot of things, but even I'm not stupid enough to do something like that. Only Matsumoto would take that risk." Seeing those eyes narrow, he hurried to continue. "Besides, it's an order directly from the Head Captain himself. His Lieutenant's the one who gave me the letter, before telling me to go around collecting signatures from all the Captains and Lieutenants. It's there on the back of the second sheet."

Hitsugaya glanced at the discarded sheets, and seeing the familiar writing of the Head Captain peeking out, exhaled heavily and rubbed the bridge of his nose. The frost melted as the temperature rose to a more bearable level, and Izukai sighed. The silence was interrupted as an all too familiar voice and a pair of running feet thudding against the floor was heard.

"CAPTAIN~!" Lieutenant Matsumoto Rangiku burst into the room, not pausing for a moment as she leapt at her Captain, passing over the desk and tackling him into a hug. "I can't believe you're leaving me for an entire year! I'll miss you so much! What will I do while you're gone?!" She cried, squeezing harder, causing her victim to grunt.

"Matsumoto." He gasped. "Put Me Down." The woman squeaked out an apology, dropping her superior. The shortest of the room's three occupants took a moment to straighten himself out and adjust his haori. He took a moment to glare at the only non-shinigami in the room, who was currently clutching his sides and laughing.

Hitsugaya turned back to his desk, eyes alighting on another letter sitting on his desk. He picked it up, turning it over to find the same address and seal as before. He turned to Matsumoto, glare becoming darker. "Matsumoto…" He hissed, his voice icy and dripping with threat.

"It wasn't me this time! Honest!" She whined, waving her hands frantically in front of her.

"Unfortunately, it's true." Shouta sighed, holding up a similar letter of his own. "I got this earlier myself." Hitsugaya glared at his lieutenant a moment longer, before tossing the letter aside and sitting at his desk once again.

He rubbed his temples for a moment before grabbing another paper off of a pile. "Might as well finish this while I can…"

Rangiku disappeared after awhile, claiming she had to do something. For once, Hitsugaya ignored it, eyes glued to his paperwork. 'He must be really annoyed, if he ignores even Matsumoto.' Izukai mused, again lying haphazardly on the couch. Eventually, he grabbed the book forgotten on the coffee table, nearly falling off the couch as he did so, flipping through it disinterestedly.

He looked over at the sound of the chair moving, the Captain standing and grabbing his zanpakuto. He strapped it in place on his back, heading for the door. "It's about time we got going, Izukai." He said curtly, turning to the teen on the couch before leaving. The brunette rolled off the cushions, pulling himself up and following.

The two found themselves in the Twelfth Division Labs, both silently dreading the inevitable outcome. They stepped into the strange labs of Kurotsuchi Mayuri, who greeted them with a gleeful grin that sent chills down their spines.

"I assume you're here for your mission?"He asked with a sickening smile. They hesitantly nodded, and the Captain of the Eleventh Division practically clapped his hands in glee. "Good! Follow me!" He gestured impatiently, bringing them towards a smaller room where, laying on surgical tables, were two gigais. Both were wearing casual human clothes, likely provided by Rangiku.

"Um, I think you got the measurements wrong." Shouta muttered, peering at his, which was at least half a foot smaller than him.

Kurotsuchi scoffed. "They've been adjusted to suit the proper size of a twelve year old. Besides, I think you'll find that these gigais are much more comfortable and much, much stronger, seeing as you'll be wearing them for a much longer period of time." He explained, waving at them impatiently to put them on.

Shouta hesitantly did so, climbing into the body. "You're right; it feels great." He said in surprise, doing a few cartwheels before crashing into one of the tables. "But the height difference is like the reverse of puberty." He muttered, rubbing his back with a scowl.

Hitsugaya glared at his own, which was a few inches taller than the tips of his hair, before following suit. The brunette jumped as there was a loud snap, turning to see the snowy-haired Captain grimacing in pain. Kurotsuchi simply grinned some more at the other.

"Wh-What just happened?" Shouta asked, looking back and forth between them.

"You'll be sore for a few days, but I can assure you the effects will wear off quickly." The Captain continued on, ignoring the question. "Also, you'll still be able to use your Hyorinmaru and kido while in the gigai. However, both will be visible to humans should you choose to do so. Therefore, I've also created a way to hide your zanpakuto from sight while keeping it on your person. Lastly, you'll be under the guise as transfer students from Japan, so you'll need to know all spells and other information concerning Japanese Wizards and other bits of common knowledge. So if you'll stay put awhile…"

A glint of insanity lit up his eyes, hand holding a syringe with an unnecessarily long needle, the tip dripping with a sickly green liquid.

"Brat."

"You're a disgrace. I don't want to see you here, you disgusting creature."

"Isn't he that killer? You know the one that terrorized Japan awhile back?"

"He should be in hell for what he's done."

"I feel bad for his family. What a disgrace he must be."

"Izukai! Izukai!" A rough hand shook him, and the brunette opened his eyes, yawning. "Izukai, get up! We're leaving!" Hitsugaya snapped, leaning back and looking distastefully at the body strewn about on his couch.

"Hitsugaya? What…?" He yawned again, head throbbing painfully as he sat up and looked around the Captain's office with bleary eyes. "When'd you get so tall?" He asked, gaze settling on the head of white hair. The Captain gave him an icy glare, before turning away and hefting a large suitcase over his shoulder. Getting the message, the brunette crawled off the couch, wobbling on his feet as he picked up another suitcase with as much ease as the other.

"Matsumoto packed for us a few hours ago." Hitsugaya explained as the two dragged the large objects past the houses and other buildings of Seireitei. Shouta simply hummed in response.

Only a few minutes passed before the two found themselves in front of the Senkaimon with the Head Captain, Captain Kurotsuchi and Lieutenant Matsumoto to see them off. "It is imperative that your identities and the existence of the Soul Society remain unknown to wizards." Yamamoto eyed Shouta while saying this particular statement. "Good luck to you both."

The two nodded. "Well then, thanks for all that. See ya Matsumoto. Head Captain. Clown face." Izukai gestured to each of them as he threw out the nickname, stepping through the Senkaimon with Hitsugaya before he could be reprimanded.

Not too much of a difference with this first chapter, but there's not much plot here anyways. I will probably update irregularly, but I'm going to try to finish this as quickly as possible. It's already been written once, so hopefully that will help it go faster.
