Disclaimer: if I actually owned any of the Bleach or Harry Potter characters I wouldn't have to borrow them at times when I think their lives could use a little more adventure.
Bleach World-
"Captain, captain," Lieutenant Rangiku Matsumoto called in her what she claims "drunk, but not drunk enough," stupor. The orange haired busty woman stumbled through the door to find her spiky white haired, and somewhat abnormally short captain sitting at his desk working on the supposedly endless stack of paperwork. And it didn't help all that much that his lieutenant was drunk… again, and he had to double his workload to compensate for her lacking.
"Captain Hitsugaya," Matsumoto sang, "Head Captain Yammamoto wants 10th squad and Rukia, Orihime, Uryru Chad and Ichigo to go to some place in England called Hogwarts. It's supposedly a school for witchcraft and wizardry." She stumbled and Captain Hitsugaya stood up from his desk and walked towards her, slowly. "Captain it's weird, I didn't know there was such thing as witches and wizar-"that's all she said before she fell into Toshiro's waiting arms. It's not like he didn't know what was going to happen; sooner or later she would pass out and wake up hours later.
Toshiro literally dragged her to the couch in the office they worked in. All the while muttering about drunken, lazy, lieutenants who don't listen to their captain. As soon as he shoved her all the way onto the couch he stalked back over to his desk to finish the paperwork that he had to do, but he stopped before he reached his desk to walk out of the office and tell the rest of squad 10 to let them know that as soon as Matsumoto wakes up they will be leaving for Karakura town to get their gegi's and pick up Rukia, Ichigo, Chad, Uryru, and Orihime so they could go off to Jolly old England.
Karakura Town-
"So I'm a witch, Mr. Dumbledore?" A little girl in a yellow dress asked an old man in purple robes and a large white beard and sparkling eyes.
This man sat across from the girl in the yellow dress, whose name was Yuzu Kurosaki. Her sister Karin and her older brother Ichigo come from a long and powerful line of witches and wizards.
"Yes, miss Yuzu. You along with your brother and your sister are the descendants of a long, powerful line of witches and wizards, and I would very much like you three to come to Hogwarts School of Witchcraft and Wizardry. I am the headmaster, of the school, and even though your brother is 17 we can have him transferred to the seventh year class. While you and Karin would be in the first year class."
"I will have to talk to my-"the front door swung open and Isheen Kurosaki stepped through.
"Yuzu, darling, who is this?" Her father asked.
"Dad, this is Professor Dumbledore."
"Pleasure to meet you, Mr. Dumbledore." The elder Kurosaki said politely, "forgive me for being rude, but what are you doing in my home?"
"Ahh, you must be Isheen Kurosaki." The old wizened man said in a friendly tone. "You do know that Yuzu here and her sister Karin, are witches, and your son Ichigo is a Wizard, don't you?"
"I was aware of that, sir."
"Well you see I am the headmaster of Hogwarts School of Witchcraft and Wizardry, and I would like for your children to go to it and learn to hone their abilities. What do you say?"
"I say if Karin goes, then Yuzu is allowed, also. And if those two go than Ichigo will go because he will look out for them. So it all depends on whether or not if they want to go, and if Karin goes."
"Dad, I want to go," the sweet little girl said.
"If Karin goes than your going to be able to go. Is that all right with my precious little Yuzu." Her father told his daughter.
"Mr. Kurosaki, if they are allowed to go they will need to meet up with a student of mines family. Their last name is Weasley. They will meet you in England in front of The Burrow, from there they will go onto Diagon Ally so that they can get their school supplies. Oh and before I take my leave, there are a few others who I would like to attend. Do you know Ohihime Inoue, Uryru Ishida, Chad Sado, and Rukia Kuchki?"
"Yes, those are all Ichigo's friends."
"Well then perhaps he also knows Tos-" that was all he got out before Karin walked in the front door with her soccer ball in the bag on her shoulder and her knee all scraped up.
"Hey Yuzu. Dad , um….. and you are?" The new arrival asked the older man.
"I am Professor Albus Dumbledore, headmaster of Hogwarts School of Withcraft and Wizardry."
"O…kay, Dad?"
"It's all true, Karin, you're a witch. Your mother was, her mother, and her grandmother before her. It's a long generation of witches. And wizards, like your brother." Her father replied. "Please continue, Dumbledore."
"Thank you, Mr. Kurosaki, now as I was saying, do you know Yumichika Ayasegawa, Ikakku Madarame, Rangiku Matsumoto," he looked up and seen Karin with a shocked look on her face.
"And Toshiro Hitsugaya" He and Karin finished at the same time. He looked at her and asked "You know him?"
"Yeah he played soccer with my team and he saved my life."
"O yeah," Yuzu said, "I remember you telling Ichigo about that.
"Yeah," Karin replied.
"Do you know where he is?"
"Um…. No"
"Well then, if you see them could you give them these letters," the professor said as he handed four very official looking letters to Isheen and disappeared in a poof of smoke.
