Chapter 3: Hogwarts School of Witchcraft and Wizardry

"TENTEN!" Naruto yelled as he saw Tenten's body disappear, falling out of sight. He gritted his teeth and ran towards the woman, who was smirking triumphantly. "You'll pay for killing my friend!" He roared, aiming a punch at the woman's face. Something hard hit him from behind, and he nearly lost his footing as he coughed up blood. He turned around just in time to block a kick from the large man, Makoto.

"What's wrong, kid? Sad that your pretty little friend died? Don't worry, you'll join her soon enough!" Makoto sneered, and pulled back his fist, ready to punch. Naruto, meanwhile, growled as he focused chakra into his right hand.

"Rasengan!" He shouted as he met Makoto's punch with the spinning ball of chakra. Makoto pushed with all of his might, but the Rasengan managed to blow him back a few feet. He rubbed his steaming, burnt knuckles with a smirk on his face. Before Naruto could react, Makoto punched him in the stomach, knocking him down onto the metal roof of the train. The large man then pinned him, crushing his arms. The woman stepped over to the struggling pair and smirked.

"Don't even try, little boy. You're no match for us! I heard they put restrictions on you Konoha ninja so that your cover won't be blown. That was a mistake! Oh well…the bomb will go off any minute now. And you can do nothing to stop it!" She said with a sinister laugh at the end. Naruto growled, but found that his arms wouldn't move.

'Damn…do I have to use THAT move?' He thought as he glared at Makoto. 'The old man and baa-chan told me not to…but this is kind of an emergency…'

"Hey Asuka, can we just knock him out? Please?" Makoto asked, grinning. The woman sighed.

"Fine…he's annoying, anyways. But we're in enough trouble for killing that girl." She replied. Makoto snickered darkly as he raised his fists over his head, and the woman prepared to kick.

"By the time we're finished with you, boy, you won't remember a thing!" Makoto declared, his grin stretching from ear to ear.

"Oh really?" said a clear voice from behind them.

"Wha-" Asuka exclaimed but screeched when something slashed her back. Blood sprayed everywhere, and she fell limp to the ground.

"Asuka?!" Makoto yelled, looking around wildly. No one was there. "Who did this?" He roared, and looked down at Naruto, who was smirking mischievously. "You…You did it! I'll kill you!" But before Makoto could even raise his arms to prepare a punch, something stabbed him through his back, the blade protruding out of his stomach. He coughed up blood, and Naruto took this chance to deliver a swift kick to the man's chin. He grinned as Makoto slumped to the ground, revealing a familiar figure standing behind him, twin swords stained with blood and brunette pigtails flying wildly in the wind.

"Tenten!" Naruto exclaimed as the person grinned back. She had a bloody gash on her shoulder, but otherwise she seemed fine.

"Hey, Naruto. Sorry I wasn't here sooner." Tenten said, sheathing her swords. Asuka groaned as she lifted her head towards the two Konoha ninjas.

"What…how did you…" she muttered, wincing as blood pooled around her.

"I used the force of your slash to fall and hang on to the lower side of the train. Then I quickly erased my chakra. The wind helped a lot, too. While you two were focusing on Naruto, I snuck over to the front of the train and-" Tenten paused, taking out something from her robes. It was some sort of device, cut in half with part of the explosion tag torn off. "And I was able to destroy this. This whole plan was really risky, though. I didn't expect to get a wound this deep, and there were only 15 seconds left before the bomb exploded." Asuka grimaced as she dug her nails into her palms.

"Damn…I failed to notice…" she hissed, gritting her teeth with anger. Makoto groaned as he clutched the gaping wound in his stomach.

"Now," Tenten said, her voice changing abruptly to a cold tone. "Tell us about your organization." Asuka panted heavily, her head spinning due to blood loss.

"Fool…" she breathed, smirking weakly at the two ninjas. "We would take our master's secrets to the grave. But…I suppose I can reward you for outsmarting us." Tenten frowned, but kept listening. "Makoto and I were sent…to stop this train from reaching Hogwarts, even if we had to destroy it. When we heard the wizards had hired Konoha ninjas, we knew the task wouldn't be as simple…so we decided to destroy the train. But, as you can see…the plan failed."

"Why were you sent to do this? Why would you prevent this train from reaching Hogwarts?" Naruto asked, with his voice as cold and demanding as Tenten's.

"That's…for us to know and you to find out." Makoto replied, chuckling slightly. Naruto's eyes narrowed, but Tenten stopped him from doing anything rash.

"What is your organization's purpose? What about this 'master' you speak of?" She asked.

"Hmph…we were supposed to dispose of a boy named Harry Potter. You probably already suspected this, though. When our organization heard that Konoha ninjas were protecting Harry Potter, we decided to change our plans…" Asuka replied. Her voice was becoming lower – she was barely conscious. Knowing that they didn't have much time since the train had begun to slow down slightly, Tenten pressed on further.

"Who is your master?" She asked, but tensed when she felt a strong presence heading their way. She and Naruto jumped back as a dark cloud of smoke started to form in front of Asuka and Makoto. The smoke eventually formed and hardened into a tall man, with long silver hair and crimson-red eyes. He was wearing a dark hooded cloak that covered his whole body, only showing his face and a few strands of hair.

"My apologies," he said in a low, sinister voice. "But I'm afraid the questioning will have to stop." He glanced behind him, where Asuka was looking up with a fear and shock.

"M…Master…" she whispered, and flinched when the man narrowed his eyes.

"Asuka. Makoto. You have failed me." He hissed. Tenten and Naruto pulled out their kunai.

"Who are you?" Naruto demanded, getting into a stance. The man chuckled.

"Now, now…I did not come here for a fight. I'm here to pick up my subordinates, as you can see." He said, gesturing towards the fallen ninjas.

"Who are you?" Naruto demanded once again, his voice stronger than before.

"My name is of no importance…we'll meet again, Konoha ninjas. Enjoy your time at Hogwarts, while it lasts…" before the two Anbu's could do anything, the man vanished into the evening sky. Asuka and Makoto were gone as well.

"Damn." Naruto muttered, placing his kunai back into its holster. Tenten's face was grim as she tucked her kunai away as well.

"We'll need to talk to Neji and Sasuke about this. Dumbledore too." she said, and Naruto nodded in agreement. "Let's get our bags and head towards the castle immediately."

0000000000

Neji glared out the window as he paced slowly around the room. Sasuke stood in a corner, crossing his arms but looking annoyed. Both were in their Hogwarts uniforms, and currently waiting in Dumbledore's office. It had been a fascinating place when they first saw it – but now, all they wanted to do was smash the little silver instruments into pieces. When they had heard that Naruto and Tenten were engaging in combat with two mysterious enemies on top of the train, both had been eager to go help – but Dumbledore had told them to stay in the office until they received further news. This angered the two greatly, since Hyugas and Uchihas did not stand around and wait while their comrades were in battle. Meanwhile, various portraits on the walls stared at the two Anbu's with curiosity. One picture of an old man coughed. He winced when he was soon facing burning glares from both Konoha prodigies.

'Why do these pictures move and talk, dammit!' Sasuke thought furiously, clenching his fists in order to contain his annoyance.

"Ahem…" said a portrait of a little man, peering at them over his thick spectacles. "I believe Albus is on his way back, with your friends…" Neji and Sasuke both flinched.

'Are they injured?' Neji thought, his head swiveling towards the door as he heard the knob turning.

'Did they defeat the enemy?' Sasuke also thought, looking up from his slouched position.

"Hey, Neji and Sasuke! We're here!" Naruto said excitedly as he leaped into the room. His face had a few bruises on it and his leap wasn't as energetic as usual, but he seemed fine. He was carrying his bags, and someone else's luggage.

"Where's Tenten?" Neji asked, his eyes narrowing slightly.

"What happened?" Sasuke demanded, walking towards where Neji was standing in front of Naruto.

"Geez, what's up with you guys?" said a familiar female voice from outside the doorway. Tenten walked in with an amused smirk on her face, with Dumbledore close behind her. Neji and Sasuke's eyes traveled from her blood and dirt-smudged face, to her blood-stained robes, and finally, to the large gash across her shoulder.

"Tenten," Neji said calmly, his eyes never leaving her face. "What happened?" Tenten walked over to the chair that Dumbledore had summoned, and sat down.

"Basically, Naruto and I met Harry Potter, sensed enemies on top of the train, went to investigate, found a bomb attached to the train, fought with two mysterious ninjas, destroyed the bomb, defeated the ninjas, and got a bit of information." Tenten said casually, wincing slightly when she moved her injured shoulder.

"Ah, I'll call Madam Pomfrey to take care of that." Dumbledore said, and sent one of the portraits to find her. Soon, a woman walked in, looking slightly miffed.

"Dumbledore, what is the meaning of-" she paused, gaping at the four strangers in the room. "You…you hired children to guard the school?!" She exclaimed, rounding on Dumbledore, who merely stood back watched her rant. "And that girl is hurt! No worries, I'll tend to that right away!" Tenten cringed as the woman stomped over to the chair she was sitting in, a menacing look in her eyes.

"Children? You think we're children?" Naruto muttered under his breath, but did not interrupt the witch as she started to heal Tenten's wound.

"Thank you, Madam Pomfrey. Now, as for your question…do not worry, these four are highly capable. Actually, they have exceeded my expectations." Dumbledore said reassuringly. Madam Pomfrey huffed, but didn't say anything else. A few minutes later, Tenten's shoulder was flawless, with her robes and shirt mended as well.

"Thank you." Tenten said, offering a smile to the woman, who blinked and nodded in response. She did a quick check-up of the three boys, and once she had made sure none of them were hurt and their robes were clean, she stomped out of the room.

"She's not always like that," Dumbledore said after the witch had left. "These days, everyone is on their edge…we are just afraid to admit it…" he glanced at his watch and smiled. "Ah, it is almost time. Before we go down to the ceremony, however…I will give you a brief explanation of what you are expected to do in this school." The four ninjas nodded and listened intently. "As you already know, you must keep an eye on Harry Potter at all times. All Hogwarts students are split into four Houses: Griffindor, Ravenclaw, Hufflepuff, and Slytherin. More detail will be covered later, but Harry and his friends are in Griffindor. Therefore, I will be placing all four of you in that House."

"What are those Houses for?" asked Sasuke, but Naruto interrupted him.

"Wait! I forgot to tell you, but we met Potter and his friends on the train. And…well, because of those enemy ninjas, we were kinda forced to reveal our identities…" Naruto said, rubbing the back of his head sheepishly.

"Yes, we had no choice. We did not expect to encounter our client so soon. But we did not tell them our exact identities, nor where we came from." added Tenten, and Dumbledore nodded.

"Yes, I understand. That is fine. I plan to tell Harry of you four – not your ninja identities, but I will tell him that there are people watching over him. I do not think he will be particularly pleased with the news, but it is necessary." he said.

"Potter and his friends are already suspicious of us. They're gonna corner us eventually and start asking questions…what do we do when that happens?" Naruto asked.

"Though it is inevitable that it will happen, I will make sure to tell him about you four as soon as possible – perhaps he will refrain from asking questions if he already knows some details. Now," Dumbledore said, turning his attention to Sasuke. "As for the purpose of the four Houses, well they're used for a variety of events. For example, they compete with each other in Quidditch-"

"Quidditch?" Naruto asked.

"Simply put, Quidditch is a sport, played on broomsticks. I'm sure you will get an opportunity to see a Quidditch match…after all, Harry is the Seeker and the new captain of the Griffindor team." Dumbledore replied, smiling. "So, more about Houses…in class, if you answer a question correctly, or if you produce excellent results in the task that your teacher had assigned you, the teachers will award you by giving points to your House. There are many ways to earn points, but at the end of the year, the House with the most points is awarded with a celebration and great honour."

"I see…" Tenten said slowly. "Do we participate in these events? Our client seems to be involved in a lot of them."

"You do not necessarily have to, but yes, it will further help you watch Harry. Plus, you may find yourself enjoying those events…you never know." Dumbledore glanced at his watch once more. "It is time now. Shall we go down to the ceremony?" The four ninjas nodded, and followed him out of the room.

0000000000

The Great Hall bustled with noise as students laughed and talked. Harry, Ron, and Hermione sat at the Griffindor table, chatting quietly.

"Just who were those two, anyway?" Ron muttered as he glanced around. The two mysterious strangers, Tenten and Naruto, were nowhere to be seen.

"No idea. Where did they go? After they…jumped out the window." Harry mumbled back, thinking of the spiky-haired blonde leaping off of the windowsill of their compartment.

"And those masks! They gave me the creeps." Hermione said nervously, recalling the eerie painted masks that the two strangers had worn over their faces before rushing out of the train.

"I heard thumping and crashes from the ceiling," Ron whispered, his eyes narrowing into a frown. "What were they doing?" They could think of so many questions, but they could not find a way to answer them except for asking the strangers directly. But there was little hope that Tenten or Naruto would answer their questions truthfully, or even answer at all.

"I'm sure those two were the exchange students that people were talking about. We might see them with Dumbledore." Hermione said, glancing over to the teachers' tables. The seat in the middle, which belonged to Dumbledore, was still empty.

"Speaking of Dumbledore, the ceremony is starting a bit late today, isn't it?" Harry realized, looking at his watch. The room fell silent, however, when a familiar figure entered the room.

"I am sorry for the delay," said Dumbledore, his voice magnified by the silence of the Hall. "To old students, welcome back. To the new students…Welcome to Hogwarts!" A line of first year students appeared, following close behind a strict-looking witch named Professor McGonagall. Harry mused at how small they looked – it seemed only a short while ago that he too, had been standing nervously at front, waiting to be sorted into one of the four Houses. Now, he was in his sixth year at Hogwarts – next year was his last. Finally, after the last name was called and sorted by the Sorting Hat, Dumbledore stepped up to the front, catching everyone's attention.

"Normally, I would start the meal now, but there is some things that I would like to inform you about," he said, his eyes glancing through the Great Hall. "First off, I would like to inform you that Mr. Filch, our caretaker, has put a blanket ban on any joke items bought at the shop called Weasleys' Wizard Wheezes. Second, those wishing to play for their house Quidditch teams should give their names to their Heads of House."

"I still don't see Naruto and Tenten," Ron whispered to Harry. "Are they even here?" Harry shrugged.

"I dunno. We'll see." He whispered back, and the two boys turned their attention back to Dumbledore, who was continuing on with his speech.

"…and I would like to introduce a new member of staff this year. Professor Slughorn here is a former colleague of mine who has agreed to resume his old post of Potions master." A bald man stood up, his head gleaming in the candlelight. There were murmurs and whispers throughout the Hall as people stared at the new Potions master.

"Wait, Potions? Harry, I thought you said-" Ron and Hermione fell silent as Dumbledore spoke again.

"As for Professor Snape, he will be taking over the position of Defense Against the Dark Arts teacher." This caused the murmurs and whispered to become louder and fiercer.

"No!" Harry and his friends exclaimed, staring at each other.

"Harry, didn't you tell us on the train that Slughorn was going to be teaching Defense Against the Dark Arts?" Ron asked, staring at Harry curiously. Harry frowned.

"I thought he was!" Harry replied, unable to comprehend why Dumbledore would let Snape do the job.

"Shh! Dumbledore is speaking again!" Hermione hissed over the loud mutterings. Harry and Ron snapped their heads towards the front of the Hall once again.

"And finally," Dumbledore said, looking slightly serious. "I would like to introduce four guests, who will be participating as sixth year students in this school." Everyone stared as four strangers walked into the room. Harry and his friends' eyes bulged.

"It's…it's them!" Harry whispered, gaping at the teenagers. There were Naruto and Tenten, and two other teenage boys. One of them had black hair that was spiky at the back, with piercing onyx-black eyes. The other boy had long brown hair tied into a low ponytail at the back of his neck, and shockingly pale, silvery eyes that seemed to stare through everything in the room. The Hall was silent as every student stared.

"These four are from the wizarding world in Japan. They will be placed in the Griffindor house-" The Griffindor table broke into loud murmurs and mutterings at this news. "-and I expect every one of you to treat them as you treat your fellow students, for they are now a part of Hogwarts." Dumbledore gestured towards the four teenagers, who started to introduce themselves.

"Naruto Uzumaki." said the spiky-haired blonde, a smirk on his slightly tanned face.

"Sasuke Uchiha." said the black-haired boy, his eyes staring carelessly over the room, and his face emotionless. Ron elbowed Harry and pointed at a large number of girls, who were focused intently on the stranger's face.

"Looks like he already has a fan club." Ron muttered, and Harry couldn't help but grin in amusement.

"Tenten Kunai." said the brunette girl with her hair in long pigtails.

"Neji Hyuga." finished the last boy, and some people shivered at his empty, emotionless eyes.

"I wonder why they're all going to be in Griffindor…" Harry wondered aloud. Ron shrugged.

"Do you reckon they were sorted already?" He suggested, but Hermione frowned.

"But why would they all be sorted into Griffindor? Some of them," she said, glancing at Sasuke and Neji. "Look like they can be in other houses."

"I'm gonna ask Dumbledore about them later." Harry declared, and his friends agreed with a nod. Dumbledore cleared his throat, capturing everyone's attention once more.

"And now, before you go up to your dorms, I would like to inform you of one last thing," he said. The four teenagers walked over to the Griffindor table before sitting in a rather secluded spot. Many eyes were still focused on them, but Dumbledore continued on. "As you already know, Lord Voldemort and his followers are once more at large and gaining in strength. There is no doubt that they are planning something…sinister. I assure you that Hogwarts is securely guarded from danger, but we still must take precautions. I strongly urge you to follow all of the rules and restrictions that your teachers might impose on you, no matter how irksome they may seem. Don't forget that this is all for your safety. Should you notice anything strange or suspicious within or outside the castle, report it to a member of staff immediately." Students gave each other wary glances and there were a few low whispers. Harry was staring intently at the four newcomers, however. Dumbledore had already told him most of the details during the summer – he had an idea of the dangers that were coming.

"And that is all, for today. I know that most of you are looking forward to your lessons tomorrow…It would be wise to get a good rest and come to classes prepared. Let us therefore say goodnight. Pip pip!" Dumbledore said cheerfully, a smile on his face as the students headed out of the Hall.

0000000000

Tenten sighed as she sank into her bed.

'This place is mad,' she thought tiredly as she started to loosen her pigtails. 'Ghosts, trick stairways, missing steps, students who mob us like the scary fan girls in Konoha…' She suppressed a shudder as she recalled the big shock of when a translucent figure had floated in front of her from a wall, making Naruto yelp and pull out a kunai and Sasuke and Neji had tensed. Dumbledore had merely chuckled and had informed them that there were ghosts residing in Hogwarts. As if it was a normal thing to have ghosts flying out of walls. After the ceremony, which Tenten had found unnerving because all of the stares she and her teammates were getting, they had barely managed to make it out of the Hall and quickly headed up to their dorms.

There were noises of giggling and chatting as Tenten heard other girls walk into the room, but she pretended she was sleeping. She knew that they would immediately bother her with questions if they knew that she was awake. Eyes half-lidded, she stared up at the ceiling.

'We're finally here…'

To be continued…

Sorry if it was kinda boring, I wanted to get this chapter over with so that they can start having fun in Hogwarts:) I'm not gonna start on romance just yet…I'm gonna drop a few hints here and there, but the real romance isn't gonna appear until a bit later. Also, I had to make up Tenten's last name...I didn't know what, though, so by looking through some Tenten fanfics, some people used "Kunai" so I decided to use that too. If anyone has a better idea for Tenten's last name, I'll be happy to hear it for future purposes. Sooo, once again, reviews would be greatly appreciated! Thanks!
