AkatsukiShadow: Hello, AkatsukiShadow here! This is my second crossover, and it's another NarutoXHarry Potter crossover. It takes place in Harry's third year at Hogwarts. If was just a random idea for a fic that I had in math class a few days ago.

Note: This chapter has my first fighting scene that I have ever written in it. I hope it sounds okay.

Summary: Kakuzu, Hidan, Sasori, and Deidara are sent on a mission together by Pein. It was supposed to be a 'simple S-class mission', just go into Kumo, kill a few dozen jounins, and steal an important scroll for Pein. Right? Wrong! When they're attacked by an ANBU commander, his team, and the Raikage himself, they have no choice but to leave scroll-less and try again later. Since there is no other escape possible, Sasori uses a new teleportation technique that Pein taught him to teleport him and his team mates back to the Hideout. However, something goes wrong and the four see a bright flash and find themselves in an unfamiliar, dark forest. And what's a giant castle doing right outside the forest? And is that a unicorn?! Why the hell is this senile old man waving a stick at them?! Oh boy, how are they going to get out of this mess? Pein definitely isn't going to be happy with them... hell, he won't even believe them! "We're screwed. Seriosly." Couldn't have said it better myself, Hidan.

Dawn of Hogwarts

Four Akatsuki member crept silently through the shadows of a tower in Kumogakure No Sato, headed towards their goal; a room which held an important scroll that Pein-sama needed. As they drew closer to the room, the figure in the lead stopped and held up a hand, which caused the other three to stop behind him. "Oi, puppet bastard, why did we fucking stop?" The first figure hissed at the one which was leading them. "We need a plan, Hidan. We can't go barging in there without one." The largest figure whispered in reply, his electric green eyes seeming to glow like a cats in the darkness. "Ha! Just let me fucking sacrifice the shitty guards to Jashin-sama!" the first one, now identified as Hidan, replied with a smirk. "Not that simple, un! Listen to Danna! He has a plan, un." The third and youngest figure told the priest and money-lover, successfully silencing the two bickering men.

"Thanks, brat. Yes, I have a plan. We go into the room as silently as possible and quickly dispose of the guards. We then check for and destroy any traps protecting the scroll, grab the scroll, and get out of there. Kumo still hasn't gotten over the fact that we attempted to kidnap their Jinchuriki, so we have to be careful to not alert anyone to our presence. We're just here for the scroll, anyway. If things get too bad then I'll take us back to base with a new teleportation technique that Leader-sama taught me. If that happens, I need all three of you to have at least one of your hands touching me when I announce the jutsu. I hope that it doesn't get the point I have to use it, though, since it hasn't yet been tested." The shortest figure, the one in the lead, monotone, gazing at the other three men with half-lidded red-brown eyes. "Hai, Danna, un!" Deidara chirped, while the other two simply mumbled something in approval to the plan. "Okay. Kakuzu, Hidan, Deidara, time to move!" the red-head ordered. The four missing-nin disappeared into the shadows surrounding them and crept around the corner towards the door of the room they were headed for.

The group easily disposed of the three Chuunin guards outside the door and crept into the room. The scroll lay on a pedestal in the center of the room, and five Jounins guarded it. The four Akatsuki crept through the shadows, Kakuzu letting five tendrils from his arms loose. Before the Jounins could react to their presence, they were dead; their necks were broken by the tendrils from Kakuzu. Deidara stepped out from the shadow's cover, his single eye narrowed. "This seems much too easy, Sasori-no-danna, un." He commented as Sasori stepped up beside him. "Deidara is right; this seems way to fucking easy, even though Leader said that it was damn simple." Hidan agreed, hand creeping towards the three-bladed crimson scythe on his back. Kakuzu grunted in agreement, his tendrils returning to his stitched arms. "Yes… the Raikage wouldn't just put a small group of green jounins to guard an important scroll for no reason…" Kakuzu trailed off and tensed, narrowed eyes glued to the doorway. The other three missing-nins also looked towards the door way when they felt a group of powerful chakra sources heading in their direction.

"He's right. I do have something else planned." A cold voice spoke as the door opened wide. A tall figure stood in the door way, clothed in white and yellow Kage robes, the Kanji for 'Lightning' on his hat. Standing behind him was a decent sized group of ANBU. Sasori did a quick count and had to stop himself from groaning at their misfortune; over 14 ANBU were there, and judging by the white cloak one was wearing the ANBU commander was there as well! This wasn't good; S-class criminals or not, they could still be taken down by being outnumbered, especially if every one of their opponents were skilled, and to be an ANBU one had to be skilled. "Akatsuki scum, why are you here?" the Raikage commanded in a dangerous tone. None of the Akatsuki answered; instead, they removed their hats and got into fighting stances. There was no way they were going to tell the Raikage about their mission and betray Pein. Kakuzu slipped into a Taijutsu stance, his tendrils lifting up threateningly from his stitched-up skin, eyes narrowed. Hidan grabbed his scythe in one hand, the rope from the bottom of his weapon's handle in his other hand. Deidara put on hand into his clay pouch, the other hand raised in from of his face while gripping a kunai. Lastly, Sasori grabbed the scroll his puppets were sealed in, the coil where his stomach should be unwinding; the scorpion-like point at the tip poised threateningly near is head. He had forgone riding within Hiroku since the bulky puppet wasn't good for doing stealth missions in.

The Raikage waited a moment for an answer before raising a hand and giving the order to attack the group of missing-nin. The ANBU lunged at the Akatsuki members, weapons raised. Kakuzu side-stepped a slash from a sword and lashed a tendril at the ANBU who attacked him, successfully forcing the ANBU back a few steps. Deidara ducked under a punch to his face and kicked at an ANBU's ankles, only for his foot to be blocked by the ANBU's other foot he wasn't aiming towards. Hidan parried a sword strike with the handle of his scythe and slashed at the ANBU with the scythe's blades; the ANBU ducked under the blades. Sasori jumped back from an ANBU who had slashed at him with a kunai and summoned two of his puppets, quickly attaching chakra strings to them and having them attack with senbon, kunai, and various poisons. Deidara threw a cluster of clay bombs at the Kumo ninja, successfully blowing the face off of one. The other nins escaped relatively unharmed, a few with minor burns. Kakuzu strangled a few with his tendrils as he dodged and blocked a taijutsu attack from one of the ANBU, and Hidan slashed at their enemies relentlessly and mercilessly with his scythe. The four thought that they might actually win; that thought was destroyed when the Raikage joined in, as well as a few more ANBU and some Jounin back up arrived.

"Fucking shit! They just keep coming, dammit!" Hidan roared as he beheaded an ANBU, only to get a wazikashi through the back and out the stomach. Hidan whipped around to meet the shocked face of a Jounin; it was obvious that the man didn't expect Hidan to keep going after being stabbed in the back. Kakuzu, Sasori, and Deidara had to agree with the zealot; the Kumo nins just kept coming. Hidan snarled and kneed the jounin in the gut, knocking the breath out of him, and then slicing his chest open with his scythe.

"Danna, un!" Deidara yelped in something akin to panic. Sasori whipped around quickly, eyes widening at the sight that met his eyes. Deidara was being held still by a man who had a vice grip on each of Deidara's arms, and another ANBU was headed towards the trapped blonde, a katana raised. Sasori was quick to act, never mind his own opponents. While distracting his own opponent with one puppet, Sasori whipped his tail-like cord between the ANBU and Deidara, effectively blocking the sword strike, and maneuvered his second puppet to attack the Jounin who had Deidara trapped, forcing the man to let go of the bomber. He quickly maneuvered the puppet protecting him to block a sword strike at his head with a pair of kunai as Deidara blew the head off the guy who had trapped him. "Thanks Danna, un!" Deidara called over to the red-head, who grunted in reply to his partner. Kakuzu was now locked in a fight with the Raikage, each of the two men meeting blow to blow, neither giving in at all. Hidan was still fighting, facing off against the ANBU commander even though weapons of every kind were sticking out of his body.

Sasori made his decision of whether to continue fighting and risk his teammates' lives, or to run and fail the mission as he jumped away from a kick that an ANBU aimed at his stomach. He chose the lesser of the two evils; to fail the mission. Blocking a kunai slash with his 'tail', he yelled, "Get together! I'm getting us out of here!" to his three teammates in the midst of all the chaos, quickly sealing his puppets and putting the scroll inside his cloak. Deidara blew up the hand of a ninja before obediently rushing to his Danna's side, panting heavily. Hidan cursed the air blue, running to Sasori's side, slashing at Kumo nins as he passed them by. Kakuzu blocked a punch from the Raikage and managed to land a solid kick to the man's stomach before hurrying to where Sasori, Hidan, and Deidara were, dodging attacks along the way. By the time Kakuzu reached the others Sasori was already half way through the needed hand seals for his technique. Most of the Kumo ninjas stood back, tense and ready for anything, while a few continued attacking. Kakuzu and Hidan fought the attacking ninjas off to buy Sasori time.

Sasori finished the hand seals and focused on Kakuzu, Hidan, Deidara, and himself. "Ready!" he called to Kakuzu and Hidan as Deidara grabbed his arm. Kakuzu and Hidan retreated from fighting, placing each of their hands on Sasori's shoulders. "Dimensional Flash Teleportation Technique!" Sasori whispered the technique's name. The last thing the Akatsuki members heard before the world disappeared in a flash of light was the Raikage cursing them.

"Ouch…"

"Fucking crap! Get the hell off of me, shit-head!"

"I think I broke something…"

"What happened, un?"

Sasori groaned as Deidara landed atop him, blinking in confusion. Hidan cursed when Kakuzu landed on his chest and stomach. Kakuzu could swear he heard a crack when he landed. "Yes, you fucking broke something! My damn ribs! Get off, heathen!" Hidan roared at the larger man. "Yeah, yeah…" Kakuzu muttered, raising himself to his feet. "Sorry, Danna, un." Deidara apologized to the puppet master, looking down at him. "Just get off, brat." Sasori sighed. He was replied with a pout as Deidara stood up, helping Sasori up after him. Hidan stumbled to his feet, cursing the whole time, ripping weapons from his body and throwing them to the ground; the wazikashi included. "Fucking bastards! I should fucking rip them a new one, seriously." Hidan declared in anger, gaining weird looks from the other three ninja. "Good luck with that, un." Deidara stated, amused by the priest's actions. He then looked around and blinked in confusion.

"Danna, un… where are we, un?" Deidara asked tentatively, causing the other three nins to look around at their surroundings as well. "I don't know, brat." Sasori replied as the immortal's eyes widened; so they had noticed the surroundings as well.

They were in a forest, with huge, ancient, dark trees surrounding them. The trees' leaves were a dark green, and the bark a dark, grey-brown. A dark aura came from the trees, and the branches let little of the sunlight to the forest floor. The four all knew one thing; they sure as hell weren't anywhere near any of the Akatsuki's bases. The four were immediately tense when the realized that, straining their senses for any danger. All four whipped around quickly when the sound of hooves on leaves reached their ears, only for their eyes to widen and their jaws drop. There, passing by them not twenty feet away was a silvery-white horse-like creature with a long, pointed horn coming from its forehead. "Amazing, un…" Deidara gasped at the creature, a grin finding its way onto his face. Hidan, on the other hand…

"What the hell? Is that a fucking unicorn? What in the name of Jashin-sama?!" exclaimed the zealot, who's pink eyes were wide with barely concealed shock. Kakuzu and Sasori opted to just stare at it, unbelieving. The unicorn had stopped, and was now gazing at them through bright eyes. The five stayed like that for a few moments before the unicorn turned and galloped away and out of sight. "Well… let's go and try to find our way out of this place." Kakuzu grunted after a few more moments of silence.

"Good idea, un!" Deidara chirped with a grin. Sasori and Hidan merely nodded in agreement. That was all Deidara needed in order to jump up into the trees, landing on a sturdy branch. Deidara was soon followed by the other three, with Sasori keeping pace at his partner's side while the two immortals followed behind them.

The four of them traveled in silence for what seemed like hours, but was in reality only about ten minutes. The four had thought about where they might be and what they might find at the edge of the forest, but nothing would have prepared them for the sight before them. The four ninja stood in the tree branches at the edge of the forest, gaping in silent awe. Before them was a huge brown, stone castle with multiple towers, with a lake surrounding it on two sides that they could see. Beneath them, not ten yards away, was a hut at the forest edge. That wasn't all, though. Outside the hut was a huge man –taller than Kakuzu, for Jashin's sake!- leading a group of strange creatures that appeared half bird and half horse in front of a group of thirteen-year-old children. No doubt about it, the four were no longer in the elemental countries.

"We're screwed. Seriosly." Hidan stated dryly, gazing at the castle. "You're absolutely right, Hidan." Kakuzu agreed, closing his eyes; he felt a headache coming on.

"Danna… was this supposed to happen, un?"

"No, brat… it wasn't. Well, crap…"

"This is all your Jashin-damned fault, puppet bastard."

"You aren't helping, Hidan. Shut up."

"Fuck you."
