I know the Harry Potter and Naruto crossover is really over done but its so much fun to mess with, also an OC of mine will be appearing her whole history gets explained in another Naruto story I'm writing called Golden beast of the unknown clan. I hope you'll like it.

I would also like to note that they got Sasuke back in this story so he isn't an ass hole, also apart from when Gaara got attacked at the beginning of Shippuden this story ignores Shippuden and I've wrote it so that Gaara got Shukaku back when he came back to life coz he's just not Gaara without him and it means he and Naruto can really relate.

Tsunade sighed and stared at the assembled ANBU. She couldn't help but be proud though; Naruto, Sasuke, Shikamaru and Hinata were all really good ANBU and Naruto had even been made a captain a couple of months ago. She turned to Kakashi who was also there.

"The five of you are here because I have a mission for you," she started; she could see Naruto practically bursting with excitement. "However we're still waiting for a team member so I won't explain yet." Naruto let out a huge puff of air in disappointment. Suddenly a swirl of sand appeared next to Tsunade's desk, Naruto grinned delighted.

"Gaara!" he cried throwing himself at the Kazekage. Gaara rolled his eyes and handed Tsunade a scroll while trying to hold on to Naruto. She opened the scroll, read it and looked back at him surprised.

"You will be joining this mission?" she asked shocked. "But Gaara-kun you're Kazekage, you can't really leave your village for as long as this mission is going to take."

"That is my decision," he replied. "Besides my brother, sister and Baki are capable of taking care of things and I want to do something." She smirked slightly hearing the pout.

"Very well, the six of you are going on a mission together," she stated. "However your captain for this mission isn't going to be joining you for a while yet." They all started in surprise at that.

"But Hokage-sama," said Hinata. "Naruto is a captain now so…?"

"I know he's a captain now. But for this mission I want someone with a little more experience. I do want Naruto to be second in command though." They all turned to Kakashi. "No it isn't Kakashi."

"Then who is it?" asked Sasuke. Tsunade seemed to ignore the question.

"Right now your captain is already on a mission and should return within a week of you starting this mission, once they do they will join you." They looked extremely put out but didn't make any further comments, until Kakashi spoke.

"You mean it's…?" he asked warily. Tsunade smirked.

"Of course, someone has to keep you in line."

"Eh! Kakashi-sensei knows who it is?" cried Naruto. Tsunade chuckled, Kakashi rolled his eyes.

"I know it's kind of a rule but when you say it like that it feels like I have a babysitter or that I'm the babysitter," he complained. Shikamaru sighed.

"Are you going to tell us about the mission now?" he asked bored.

"Of course. You'll be gone for about ten months in another world to protect a magic school and more specifically a boy that attends it," Tsunade said with a straight face. Everybody, except Gaara and Sasuke, let their jaws drop.

"A magic school?"

"In another world?"

"Ten months! No ramen for ten months!" They all rolled their eyes at Naruto's contribution. Kakashi pouted under his mask.

"Do you have to Tsunade? I only just got back from a mission." She smirked at him and he cursed under his breath.

"Now, now. You're only upset because you'll have to survive without Iruka-sensei for so long." Kakashi pouted even harder and started reading his book.

"Now I know we don't usually send lovers on missions together," she said staring pointedly at Naruto, Gaara, Sasuke and Hinata. "But I was requested to send those who I thought would be best suited for the job. Plus the payment is a small fortune."

"So how come the Kazekage is coming?" asked Shikamaru ignoring Gaara's glare.

"I asked him to lend us one of his ninja to help, I didn't think he would do the job himself." She turned to him frowning. "Care to explain?"

"I wanted something to do. Besides if there are any immediate dangers to my village my brother and sister can easily contact me," he explained. Kakashi snickered.

"I bet you were just panicking at the idea of not seeing your Naru-chan for ten months," he chuckled dodging a quickly thrown kunai. "Hey it's not fair if my love life is the only one that gets commented on."

"Quit bickering," sighed Tsunade. "For this mission two of you will be required to go undercover as teachers while the others go as guards. Usually it would be up to your captain to make this decision but since they're not here… Kakashi and Gaara will go undercover as the teachers. Naruto, Shikamaru, Sasuke and Hinata will go as guards." Gaara blinked in surprise.

"You want me to go undercover as a teacher?" he asked almost incredulously. "You want me to teach? Alongside the pervert?" Kakashi twitched. Tsunade smiled slightly.

"Yes, Kakashi is obvious because he's the oldest, the rest of you are barely old enough but you have the most commanding air out of the rest. It helps that you're used to giving orders. I could ask your captain to do it but they won't be there for the start of term which could cause problems." Gaara sighed and nodded his consent. "Now that's sorted I want you back here at noon tomorrow to leave." They all nodded before disappearing. She moaned once they'd left.

"Damn I'm going to have some explaining to do to an angry Chunin."

At Hogwarts:

"Ouch Sasuke-teme! Watch where you're standing!" yelled Naruto as they arrived.

"It's not my fault! I didn't know it was going to do that!"

"Ano… we're being stared at," whispered Hinata.

They all looked up and sure enough a bunch of adults were staring at them. The old man at the front stepped forward smiling.

"Welcome to Hogwarts. I understand you are the ones your Hokage sent?" he asked. They nodded. One of the teachers spoke up.

"Albus what have you done now? You said you were hiring guards," said Professor McGonagall.

"These are our guards."

"But that red haired lad looks barely older than some of our students!" Kakashi and Gaara were the only ones not wearing ANBU masks since they were going undercover as teachers. Dumbledore smiled at them.

"Could you please remove your masks? Unfortunately we live in untrusting times." The shinobi all exchanged glances. Then as one they removed their masks, except Kakashi who never takes off his mask. The teachers all gasped in surprise.

"Albus you hired children!" Naruto scowled.

"One of them is blind!" Sasuke growled at the teacher who made that comment.

"She isn't! All her family have eyes like that."

"Besides lady we're eighteen! We've been doing this for a long time thank you very much!" The others all nodded in agreement.

"We may have shown you our faces but we are forbidden from telling you our names," drawled Shikamaru. "We're ANBU, when on a mission the only ones who know our true names are our team mates and our Hokage. You will call us by our codenames." Dumbledore nodded smiling.

"Of course, what are your codenames?" he asked.

"Stag," said Shikamaru tapping his mask.

"Rabbit," whispered Hinata tapping her mask too.

"Raven," muttered Sasuke also tapping his mask.

"Fox," said Naruto with a grin also tapping his mask. "I'm also second in command for this mission." The teachers had by then realised that their codenames were the animals on their masks.

"So you four are the guards then," mused Dumbledore, he turned to Kakashi and Gaara. "And you two I assume are the ones going undercover as teachers." They nodded.

"I'm Kakashi Hatake."

"Gaara." One of the teachers frowned.

"What's your full name boy?" Gaara glared at him.

"I do not have to answer that and any attempt to make me do so against my wishes will be met with severe consequences. You don't have the power to make me." Dumbledore blinked in surprise.

"What is your rank Gaara, if you'll tell me."

"Kazekage." Dumbledore looked shocked before smiling and bowing.

"Forgive me, I wasn't aware that the Hokage would be sending someone of your stature." Gaara rolled his eyes.

"Please don't talk like that, it's annoying."

"Of course, you must tire of hearing it." He smiled. "Though I am honoured to meet the Kazekage in person and that you will be carrying out this mission. After all you have your village to think of." Gaara nodded.

"The ties with my village and the Hokage's are strong," he said glancing at Naruto who grinned. "By the way, my name is Sabaku no Gaara."

"So I take it you will be the captain for this mission?" Gaara shook his head.

"Our captain will be here within a week," said Sasuke. "They are on another mission at the moment and will be joining us the minute they get back." Dumbledore looked surprised.

"But surely Gaara should be in charge, holding the highest rank?" he asked confused.

"Our village was the one given this mission so the leader is someone from our village," explained Kakashi. "Other than that its someone with experience and most suited to the mission." He smirked. "After all Gaara is only 18, he's only been Kazekage for four years." Gaara twitched.

"Thank you for reminding me, I guess that makes you ancient." Kakashi choked.

"Hey I'm not that old! I'm 31!" He paused. "Ok for a shinobi I guess that is kinda old, I'm lucky to have lived this long." Dumbledore nodded understandingly.

"So your captain is older than you?" Kakashi shook his head.

"I am the oldest but our captain is still older than the rest of them," explained Kakashi. "They're the best suited to this mission so they're in charge." The teachers all exchanged disbelieving looks.

"Look we don't care what you think," growled Naruto. "We're going to do our job whether you like it or not." Shikamaru sighed and rubbed his forehead to try soothe the headache he knew was coming.

"This is going to be so troublesome."
