Hi, so this is the prologue chapter to my Naruto and Harry Potter crossover. The cover image Is of my character Rei. I love crossovers with Harry Potter that involves the characters from the other series coming in as guards, particularly in the 5th and 4th books which are my favorite books in the series respectively and sadly I have a hard time finding them, so I decided to give life to the little plot bunnies living in my head and I hope you enjoy.

Disclaimer: I do not own Harry Potter or Naruto or the characters. I only own Rei and her family as I am the one who created them

I looked up from a family scroll to a knock on my bedroom door. My grandfather's voice followed the knocking.

"Rei, you've been summoned by Lady hokage."I jumped up and opened the door, rolling up the scroll. Smiling at my grandfather.

"Thank you papa, I'll head to the tower right away." Setting the scroll down on my desk, I made my way downstairs. The house was quiet, with both my parents out on missions and my younger brother at the Academy, it was just my grandfather and I. Slipping on my sandals I stepped outside. Making my way down the semi-busy street towards Hokage Tower.

It didn't take long to reach my destination, walking down the familiar hallway that lead to Lady Tsunade's office. Knocking on the door, I waited..

"Come in." Opening the door I walked in and bowed.

"You summoned me Lady Hokage?"

"I did, I'll explain why once the others arrive." I straightened and nodded, we didn't have to wait long the others trickled in rather quickly. First came Neji Hyuga, followed by Kiba Inuzuka and Akamaru. A few minutes later Shikamaru wandered in. Tsunade leaned forward in her chair, placing her elbows on her desk, lacing her fingers together like a bridge.

"Good, you're all here. Now, I have a mission for you all. A man named Albus Dumbledore has contacted me with a job request and I chose the five of you to carry it out. Dumbledore is the Headmaster for a school called Hogwarts; School of Witchcraft and Wizardry. It's a school that teaches magic to the young witches and wizards of magical Europe. As you learned in the Academy, Konoha has had some dealings with the magical community in the past but have not had any contact with the lands outside of the Elemental Nations for quite some time. Early this morning I reserved the letter and payment from Dumbledore, requesting four shinobi to guard his school, because at the end of the last school year a dark wizard who was believed dead returned and killed one of his students." She let the information sink in for a minute before continuing.

"While you are in his employment you will be temporary members of a secret society that is fighting against the dark wizard and will spend your first month in their headquarters. He has also noticed that his students are, as a majority, very out of shape and to reliant on their magic for defense which can easily be countered by disarming them of their wands. These wands conduct their magic and are the only way for them to access their magic and use their spells, so he would also like you to teach physical education and self-defense classes while you are at the school. You will be gone for ten and a half months, your meals and anything needed for your classes will be provided for you and I will expect weekly reports from the squad leader. Your squad leader will be Rei Yuki."

"Me? My Lady are you sure I'm fit to be squad leader?" I asked with surprise, looking at the Hokage.

"I am sure, I believe you are the best suited for that position, especially with the political battle you will be going , how is your English?" Kiba spoke up from beside me.

"We had to learn it as a second language in the Academy, we had to be able to speak it fluently before we could graduate." The rest of us nodded our confirmation. Tsunade nodded.

"Good, now go prepare to leave and be back here by dawn tomorrow. I will give you the last few details and send you on your way." With quick bows we all headed home to prepare for the long mission ahead.

~ Just Before Dawn~

I knelt down to hug my crying younger brother close, he clung to me tightly as he sobbed. I kissed the top of his head and rubbed his back soothingly. "It'll be okay Yoshi, I'll be back before you know it."

"B-But, It's s-s-so long!" Yoshi choked out between sobs, clinging tighter to me.

"I know kiddo, but it'll fly by." Gently pulling away I gave a quick hug to my grandfather.

"Stay safe Rei and good luck." I smiled, ruffled Yoshi's hair then set off for Hokage Tower again. I arrived right on time, knocking and entering the Hokage's office, this time I was the second to arrive, beaten by Neji. We nodded to each other in greeting as Shikamaru and Kiba arrived. Tsunade wasted no time as the last arrived. She pulled out a rusted and mud covered shovel.

"Alright, I will be quick. This is a port-key. You will all grab onto it and it will take you to an alley a mile from the headquarters. A man named Alastor Moody willbe waiting for you, he will say, 'The wind is strong and cold this morning.' Rei you will answer him with, 'A warm fire would be very much appreciated.' He will then take you to Number Twelve Grimmauld Place is London. There you should meet the client and other members of the Order." She checked the clock on the wall and quickly held out the shovel. "Now grab on, it's almost time."

We each grabbed onto the shovel, Akamaru biting down on the handle. Tsunade quickly let go, at first nothing happened then suddenly I felt a tug behind my naval and we were gone in a fast paced swirl of colors.
