Disclamer: I don't own Naruto or the characters or the original story. Samething for Harry Potter.

A.N.: Hi everyone. This is my first fanfic in english (I speak french, I'm from the province of Quebec), and my first try for a cross over. I hope that you'll like it. Please review, but don't flame me. I'll ignore every review that is writen like "you're just a son of a bitch" or "You don't deserve to live in this world".

Another thing before the story begins : I'm searching for someone that can correct my grammar and spelling, so if someone want the "job" (I'm not paying for it) said send me a message. I would prefer somebody that talks perfectly in english and in french, but talking in french is not necessary.

Let's the story begin.

Clash Between Magic and Jutsu

Chapter One

The sun was quite bright that day. The two guards at the entrance were merely sleeping. Suddenly, something passed in front of them. It was him, the little guy that caused them so much trouble… well, he wasn't has little that he used to be. That boy was Naruto.

The boy was followed by Jiraya, aka: Ero-Sennin. They were walking in the streets, toward the Hokage office. Naruto and Jiraya were stopped by a feminine voice that was calling them. Sakura was running toward them, Konohamaru and the two others with her.

(From that point of the story, everything is the same, from Sakura thinking that he has grown up, to the end of the bell test.)

Two days later, Sakura, Naruto and Kakashi met Tsunade, for an important mission.

"We have a mission for you; an owl brought it an hour ago. This will be tough for you guys; it's a one year mission."

The two young shinobi looked at their Hokage, wide-eyed.

"What? But I just came back from a 2 and half year training!" Nearly cried Naruto

"I know Naruto, but I'm choosing you because one point in this mission is directly concerning your old teammate." said Tsunade, with a serious expression on her face.

Now, even Kakashi was staring at his master, his breath speeding up a little.

"Orochimaru has joined forces with the most evil person in the wizardly world."

"Which world?" They all asked at the same time.

"Yes, you heard me, the wizardly world." The blonde woman said, in a monotone voice.

"Isn't it a barrier between our worlds?" Sakura asked.

"Yes, but a high level shinobi or wizard can easily pass through it." Answered Tsunade.

"Anyway, a man of the name Albus Dumbledore is hiring us to protect Harry Potter, the only victim that survived Voldemort, the evil guy I was talking about."

"So, if we found Orochimaru there, Sasuke will be with him?" Naruto asked, getting excited about a fight that could possibly occur between them.

"Yes." Shortly said Tsunade. "Now, you'll be going with Ino and Choji."

"And Shikamaru?" Asked Naruto.

"He's currently in the hidden sand, for the preparations of the Chuunin exams. You're departure will take place in 3 hours. Kakashi, don't be late, or won't be able to go with them."

"I can't promise anything, maybe an old woman will need me to cross the street." Said the masked man.

Tsunade then twitched, and when she was twitching, it wasn't a good sign.

"Ok, ok, I'll be in time." Said desperately Kakashi, sweet-dropping.

(Three hours later)

Naruto, Sakura, Kakashi, Ino and Choji were now waiting in Tsunade's office. There was an odd looking boot on the desk. It was brown and the lace was missing. It was patched a lot of times. Tsunade then started talking.

"This boot is a portkey. It can transport you anywhere in the world; the destination is chosen when it is created. This boot will transport you all directly in the castle you'll be living in this year."

"What?!? A castle?!?" Ino shouted out. "I can't wait to be there!"

"So, what do we nee to do for it too work?" Sakura asked.

"It will do all the work, you only need to touch it and don't let it go. The time of teleportation is also chosen when the portkey is created." Tsunade told them.

"Alright! Here I go! I will find Sasuke and bring him back!" Naruto said, with his signature grin on the face and the thumb in the air.

"Now everybody, touch the portkey."

Every present shinobi touched the boot, with a little hesitation, like if the portkey would jump at the last moment and eat them to death.

"Five… Four… Three…"

The portkey started shaking,

"Two… one…"

The office started spinning around them, and soon, multiple colors were surrounding them. Ino had her eyes close and she was screaming to death. Choji was so afraid that he was silent. Kakashi was read (Don't ask me how) the book that the blonde boy had given him few days before. Sakura had a strange reflex: she took the free hand of Naruto, but he was too busy being scared to notice it, but Sakura did and she became a little red.

Everything stopped as fast as it started. Sakura felt on the ground, causing Naruto to fall with her. Sakura got up so fast that even the sharingan couldn't saw it.

"Sorry." She quickly said to Naruto.

"No, it's ok, just don't go that hard next time." Giggled Naruto.

The shinobis were at the entrance of a giant castle. The wooden doors were big enough too let a dragon enter. A bearded man stepped out. His beard was long, long and white. His hairs were as white as his beard. He looked really tall and old. His face was telling them that he had lived a lot of things and experiences. Half-mooned glasses were placed on his nose.

"Hi, my name is Albus Dumbledore, the director of Hogwarts, school for young wizards. Thanks for coming." Told the man, with a strong accent. "Please, let me put a spell on you all, so others will understand when you speak, and you to understand others when they are talking."

They all agreed with a head sign. Dumbledore then picked up a strange stick for his pocket. He said something in a strange language, and pointed the stick on the group of ninjas. A warm blue halo covered them. The halo faded away, leaving a strange sensation in there mouths and ears.

"So, do you understand me now?" Dumbledore are gently.

"Yes!" They all said in a chorus voice.

"Than, follow me, you may be hungry after this little traveling." He said, smiling at the shinobis that were standing in front of him.

"Ramen! I want some ramen!" (Guess who's talking)

Naruto felt a fist coming in contact with the left of his jaw. He flew a couple of meters away.

"Excuse him for his lack of politeness professor." Said Sakura, lightly bowing.

"That's not a problem. Than, follow me everybody, we'll have dinner together and I'll tell you anything you need to know." The director turned his back to the shinobis and started walking in the corridors of the castle.

Update: I just found a corrector :XxPoisned DreamsxX. (thx Xoom for the correction and comment: I won't put something like that anymore). I can't belive it! only an hour that my story is published and already three people have put it in their alerts list. THANKS ALOT!
