Disclaimer: I own none of the characters in Harry Potter or Naruto. What I do own, is this story.

Pairings: DeidaraxSakura. Don't like it? Tough luck.

Author's Note: Recently I have a strange fascination with Harry Potter/Naruto crossovers. My other work is Hogwarts and the Shinobi. I will be writing both at the same time, depending where my muse decided to lead me, so in result, my updates may be a bit slower. There's not a lot of Akatsuki in Harry Potter world, and less so with Deidara and Sakura, so I'm writing one! I got a feeling Itachi's being slightly out of character here, but hopefully not by much. Please review and tell me what you think!

Chapter 1 – This Cannot Be Happening

Sakura panted as she raced across the treetops towards Konoha. How could she be so careless! Letting them sneak up on her like that.

Sakura took an extra long leap from her branch to the next one while reflecting what had happened. She was taking a relaxing weekend off at a resort near Konoha for free. The owner of the resort was the client she worked for. Sakura was sent to find his daughter who had wandered off into the woods. It was a C ranked mission, and Sakura, a chuunin whose medical skills were now on par with the Hokage herself, had accepted. Sakura was now sixteen, turning seventeen in a month's time. She could have gone for the jounin exam, but being a medic in the hospital took up most of her time. She found the girl in a bandit's camp, and rescued her in under five minutes (decimating the camp site while she's at it) and returned the lost girl to her father. Sakura's client was so pleased with her work that she was invited to stay for two days for free as VIP guest. What girl could refuse?

After Sakura had travelled a few miles, she noticed chakra signatures rapidly closing in on her and cursed. She hadn't noticed them until now, and the chakra felt insanely strong. She broke into a run, and jumped up into the foliage of the trees. She turned just in time to see three figures in Akatsuki cloaks sprinting after her. She recognized them and put in more effort in escaping. Her fighting skills had improved, heck, she could split open the earth with a fist! But that doesn't mean she's suicidal, taking against not one, not two, but three S-classed criminals. Not to mention one of the cloaked figures was Uchiha Itachi.

Sakura took stock of her surroundings. There's still around ten minutes to go until she arrived at Konoha's gates if she kept up this speed. Pushing herself, she dodged the attacks thrown by the Akatsuki, inevitably getting minor injuries in the process, and racked her brains for the information on the other two.

Ah, she remembered. The one that looked like a shark was Kisame, and the Ino-look-alike was Deidara. Who, come to think of it, had a partner called Sasori, who in turn was killed by her. Shit. Sakura panicked. She turned around suddenly and kicked the tree trunk next to her in a shattering force. The tree groaned and fell, right towards the three missing-nins.

"The hell!" Kisame cursed. He swung his sword up and cleaved the massive trunk in half, letting the wood fell to the ground below. "Itachi, do we have to go through with this shit?"

"The Leader had requested us to recruit Haruno Sakura as Akatsuki's medic. Our orders are to capture, not harm." Itachi said.

"Tch, what do you mean requested, un? You mean ordered, and threatened us not to come back unless we have her. Damn, how come she's going so fast, un?" Deidara said irritatingly. He wished he could just blast the girl away and be done with it.

"Leader also wanted her for her impeccable chakra control." Itachi said. "She can't keep this pace up any longer."

Just as he had finished the sentence, the Akatsuki members saw her falter, almost missing a branch. Deidara sent a clay bird, built for speed, towards her. The bird landed on the tree branch Sakura was about to land on and exploded.

"KYAA!" Sakura shrieked in surprise, but hit the next branch to catch herself, then propelling off it to a tree trunk, then the trunk beside it, then back to the original trunk back and forth until she was on the ground. She whirled around and glared at the three figures now standing before her.

"What do you want?" Sakura yelled as he slid into battle stance. It just occurred to her that they had not tried to kill her. They could've done so easily, but hadn't.

"Taking you back to Akatsuki." Kisame yelled back, face splitting into a grin showing his sharp teeth. He heaved Samehada to rest on his shoulder. "Need you to be our medic for us."

"What made you think I would come willingly?" Sakura said.

"That won't be a problem, you're coming whether you liked it or not, un."

"Make me." Sakura's eyes narrowed dangerously. With a battled cry, she split the ground with her foot, the ground splitting and heaving.

"I shall take up the offer then." A cool voice said behind her. She snapped her head around and found herself staring into the Sharingan belonging to Itachi, his kunai at her throat.

"Damn that bitch is scary." Kisame muttered as he and Deidara jumped over overturned earth and bulging rocks jutting from the ground.

"Tell me about it, un."

As the missing-nins from Mist and Iwa landed next to Itachi and Sakura, the ground began to grow black.

"What the – " Kisame tried to move but couldn't. "Itachi, please tell me this is your idea of a prank."

The Uchiha glared. It wasn't him. Sakura felt the glares of the three missing-nins.

"It wasn't me!"

The world went black around them as they were sucked into the ink of black. After their disappearance, the black shadow started to shrink until it disappeared.

"Peeves! What have you done?" Filch yelled in fury and distress. The caretaker had arrived when there was a commotion in one of the dungeon rooms and was now staring in horror at the inky blackness on the ground. The ghost was cackling gleefully, practically rebounding off the walls.

Attracted by his call, the Professor Snape and Professor McGonagall came to investigate.

"Argus? What's going on?" McGonagall asked as she and Snape stepped into the room.

"It's Peeves! He – "

The blackness on the stone floor started to bulge. A lump was rising from it. McGonagall and Snape instantly whipped out their wands, watching the growing lump cautiously.

"Severus, could you –?" Professor McGonagall began. Snape nodded, turned around and with a billow of his robes he was gone to get the Headmaster, having bigger strides than the Transfiguration professor to get him to his destination quicker.

Peeves had disappeared. Filch and McGonagall watched as the blackness began to recede. Filch's mangy cat backed up against her master as she hissed and spitted at the lump, her hackles rose. Bit by bit, the huge lump could be made out as four bodies. As the blackness dripped off them like ink, Professor McGonagall could see that there were three boys and a girl in odd clothing and were unconscious. As the black disappeared altogether, the professor was startled and realized one of the boys had features like a shark.

Hurried footsteps were heard. Seconds later, Dumbledore rounded a corner and into the room with Snape at his heals. He took one look at the four on the ground and conjured up stretchers and lifted the bodies onto them.

"We'll talk in the hospital wing. First we must let Poppy see to these people." Dumbledore said and walked out of the room, stretchers in tow.

Sakura groaned. Her body aches. She felt tired. Sakura shifted uncomfortablely under the sheets then stilled suddenly. Sheets? The last thing she remembered was being chased by the Akatsuki because they wanted to recruit her, then Itachi was holding a kunai against her throat, then…nothing. She snapped her eyes open and sat up suddenly. But the sudden bright light forced her eyes shut again, a headache made itself known from getting up too fast. Someone was pressing her gently back into the bed. Sakura resisted a bit but set her back against the headboard of the bed. She heard a woman cluck her tongue and was speaking to her in another language. Sakura frowned. That was strange. She'd never heard of another language other than her own before. Sure, different countries had different dialects, but it's the same language. Sakura opened her eyes.

She was in some kind of infirmary. The woman who appeared to be a nurse was frowning at her, still talking in another language, sounding annoyed. Sakura frowned back.

"Where am I?"

The woman looked surprised. Sakura had asked in her own language. As the nurse tried to get through to her again, Sakura looked around the room. Beds were placed in neat rows in the infirmary. Long, elongated windows spilled sunlight into the room. She caught sight of the other occupants in the three beds next to her and stiffened. It was the Akatsuki.

Sakura saw movement from the corner of her eye. Three people in odd clothing were walking towards her. There's a guy who had greasy hair and looked constantly constipated, and a foreboding woman, lips in a thin line. At the front was an old man, who caught Sakura's attention immediately.

He was tall for his age, very tall – probably around the same height, if not taller, than Kakashi. His hair and beard was white, and very long. He wore a strange midnight blue coloured robe, and had a pair of half-moon spectacles resting on his crooked nose. Blue eyes twinkling as he smiled down at Sakura, saying something. Sakura furrowed her brows in incomprehension.

"What did you just say?"

The three people looked startled. The nurse started talking to the old man. Sakura glanced down and saw her kunai holster and her forehead protector on the bedside table. She grabbed it and strapped it on under the sheets, and checking to see if anything was removed from it. She tied her forehead protector back on like a headband and noticed her bag on the ground beside the bed. She noticed that the old man was trying to get her attention. She looked back around questioningly.

Why the hell was he pointing the stick at her? A stream of blue light shot out and wrapped itself around Sakura before she could move out of the way. It disappeared in an instant, but she immediately started shouting.

"WHAT THE HELL DID YOU JUST DO TO ME?!" Sakura slapped a hand over her mouth, her eyes wide. She just spoke in a different language!

"Ah, the spell worked then." The old man smiled, a twinkle in his eye at Sakura's reaction. "Now we could talk."

"Where am I?" Sakura asked cautiously.

"You're in Hogwarts School of Witchcraft and Wizardry." The stern woman answered. "How did you get here?"

"How should I know?" Sakura snapped, her patience wearing thin. She was tired, annoyed, and these people are telling her that she's in a school of magic. She's not a little girl to be humoured. "I'm in no mood for jokes, there's no such thing as magic."

"I beg to differ." The old man said, still smiling. He gave a wave of his wand, and the water jug on Sakura's beside table moved. She jumped and saw the jug pouring water into the glass; the glass in turn floated up and moved in front of her. Sakura waved a hand around it, checking to see if she could feel chakra strings like Kankuro did with his puppets.

"Ehhh?" Sakura stared at the water in disbelief. The glass gently nudged her on the cheek, as if telling her to take it. Cautiously, she took the cup, and felt its weight in her hand. She downs the glass quickly, wishing it were sake.

"So these are muggles then?" The greasy haired man with a hooked nose said. Sakura frowned, not knowing what muggles are, but it sounded vaguely insulting.

"Ah, where are our manners? We haven't introduced ourselves yet." The old man said. "I am Albus Dumbledore, the Headmaster of this school. This is Professor McGonagall and Snape. And the lovely woman there who treated you is Madam Pomfrey."

Sakura nodded cautiously.

"I am…Sakura Haruno, a Chuunin from the Hidden Village of Konoha." She noticed that family names go last judging by the way that the headmaster had introduced the professors.

The one called McGonagall frowned.

"I have not heard of such a place. Which country do you belong in?"

"The Fire Country."

"Are you playing a joke on us?" Snape said, face dark. Sakura had an instant dislike towards this man.

"No, that's where I'm from!"

"What about your friends over there?"

"They're not my friends," Sakura shot a glare at the still unconscious trio. "They're criminals from where I came from."

Before anyone could say anything else, a kunai whizzed through the air, but Sakura caught it. Gasps were heard. Itachi was wide-awake, his Sharingan activated.

"What did you do?"

"I didn't do anything." Sakura was surprised to find that she could still talk in her own language. She sent the kunai back at him, letting it imbed into the bed an inch from his head. Dumbledore looked worried for a moment, eyeing the weapon in the bed before turning to Sakura.

"Would they like to have a language spell cast onto them?"

Sakura was still dubious of this spell thing. She only heard of them in fairytales. Regardless, she turned to Itachi.

"He's going to make you understand their language. He did the same thing to me."

The Uchiha narrowed his eyes dangerously.

"How do I know he's not going to do that?"

"Then bad luck. You want to or not?"

Itachi's red eyes slid to his teammates on the beds next to him. Then nodded. Dumbledore saw this and cast the same spell on the three Akatsuki members.

"Now," Dumbledore said, "shall we discuss about this situation?"

Dumbledore, McGonagall and Snape had left, leaving Madam Pomfrey to fuss over the ninjas. Kisame and Deidara had woken up half way through Sakura's explanations about her world (Itachi just sat there like a log). As Madam Pomfrey fluffed up Deidara's pillow and left to get one of her remedies to dispel headaches, the blonde grinned and munched on a chocolate bar.

"I like her, yeah."

Kisame grumbled. The nurse had asked him who had cast a jinx on him to make him look like a shark, and that she'll help undo it. Before Kisame could explain, Madam Pomfrey had her wand out. She was perplexed as to why nothing happened when Kisame snapped at her, saying it was his natural face. Deidara laughed so hard that he fell off the bed. Itachi was, as usual, silent, but was staring at Sakura, who wasn't talking. She was lying on the bed, back facing the Akatsuki, trying to tune them out.

"Are you done ignoring us now, un?" Deidara asked the pink haired medic, annoyed.

Sakura's silence answered for him. She wouldn't admit it, but she's actually pouting, chanting 'This is not happening this is not happening' over and over in her mind. Now she had to put up with her enemies, stuck in a world she doesn't know, apparently a magic one, and had no way of getting back home. The wizards had said that they'd interrogate Peeves (she still can't believe a ghost made this mess) and figure out how to undo it. Dumbledore said he may have an idea but he needs it to be confirmed. In the mean time, the four were to remain in the castle. Tomorrow will be the students' first day back at Hogwarts, so add to the whole mess, Sakura would need to try and keep the Akatsuki from killing anyone.

Sakura huffed as Kisame and Deidara started another fight. Another thing was that it's getting increasingly hard to hate the Akatsuki's guts. How could she when two of the members are acting like five years olds?

"That's my chocolate, yeah."

"You're not eating it! Since you aren't, I will."

"I'm saving it, yeah!"

"Just ask another one from the nurse. I'm bigger than you, I need more energy."

"What kind of crappy excuse is that, un? And when did sharks eat chocolate, yeah?"

Sighing, Sakura snuggled further into the bed, pulling the sheets up until it covered her head. Right after the professors had left, Itachi had confronted her. They now had a temporary truce. But during their stay here, the Akatsuki would continue to persuade her in joining their organization (since they can't force her into it in a foreign world).

Sakura turned around, lowered the sheet and peeked at the criminals. Itachi had his eyes closed, a slight frown on his face, a hand covering his eyes. Kisame and Deidara continued to argue. Sakura sat up, her medic instincts kicking in.

"Does your eyes bother you?"

Itachi glanced sideways.

"It's nothing."

Sakura scowled, recognizing the common ploy shinobis used constantly to get out of the hospital. Tossing the blanket off her, she stood up and sat on Itachi's bed. His slightly surprised gaze met her firm emerald orbs.

"Since we have a truce now, might as well let me look at it. Your continuous use of Mangekyou damages your eyesight. I don't want a blind ninja while we're stuck in this world."

Her hand stretched out. Itachi turned his head away. Annoyed, Sakura used both her hands and grabbed Itachi's head, using her super-human strength to turn his head back around. Itachi was startled. He does not understand this kunoichi. First she tried to kill them, then tried to ignore them, and now she wanted to heal him?

"Deactivate your Sharingan."

Itachi did as he was told. With his head in-between her hands, he had no desire to see the inhuman skills the Hokage had passed down to her. Green light enveloped Sakura's hands. The light extended until it covered his eyes. Dimly, Sakura was aware that the explosion expert and the shark had stopped to observe. A few minutes later, Sakura was done.

"I'll need to do regular sessions each night for that eye of yours. You're not allowed to use the Sharingan for an hour after each session." Sakura said professionally, ignoring the missing-nin's glare and slipped back into her own bed. She rarely healed eyes, which were the optometrists' job in the village. The only times she dealt with them were when she did transplants or surgery. But as the Hokage's apprentice, Sakura had learned every aspect of the human body. Needless to say, having worked in an area she did not specialize in tired her out. A minute later, she was sound asleep. Kisame peered at the silent Itachi.

"So…is your eye better?"

Itachi sat unmoving for a while before giving a barely there nod. Kisame gave a low whistle. Deidara molded a butterfly to pass the time. He then let it fly around the room.

"We gotta get her in Akatsuki, yeah." Deidara made a mini explosion from the butterfly.

"Albus, is this such a good idea in letting these…these…mercenaries staying here?" McGonagall asked, worried.

"It is our responsibility. Peeves had dragged them into this world, and to make matters worse, he did not remember what he did to cause this." Dumbledore said, resting in his armchair. "Luckily, I do know about their country. I was friends with their first village leader, and had known their third when he was a child. But that was a long, long time ago."

"How did you…?"

Dumbledore sighed and stood up, stroking his phoenix, Fawkes.

"This world is full of mysterious, Minerva. I had discovered this, veil if you will, between their world and ours. Their language is identical to Japanese from the East. In Japan, things such as ninjas to their level are myths, but had managed to create warriors similar to them for a period of time. This veil is near Japan, but none are aware of it. Their country actually overlaps slightly with Japan.

"I had discovered this veil by accident in my younger days, and found myself in the wilderness due to a spell gone wrong. Fortunately, I was just a few miles away from the Hidden Village of the Leaf, the place where the pink haired young girl, Sakura I believe, was from. Their leader had welcomed me, mainly because he was fascinated with my magic. Frankly, if I had not had it, I'm not sure if I will be here today. In a few months, I managed to find my way back home."

Dumbledore sighed.

"Unfortunately, it will take time to find away to send them back home. If the spell went wrong, we could send them back but into a different time, or send them into a hostile country, where their chance of getting back into their homeland in their world would be slim."

McGonagall sighed.

"But do they have to stay here? Couldn't we provide accommodations for them some where else?"

"It'd be best for them to stay here. Besides, we could employ them."

"Employ them? For what?" The Transfiguration professor was aghast.

"With Sirius Black on the loose, extra protection would be needed."

"But the Dementors – "

"I'd sooner trust ninjas, killers as they were, than Dementors." Dumbledore cut his friend off grimly. "At least ninjas, even rogue ones, had some sort of code of honour. Dementors knew none."

Review please XD
