A/N: This story might be confusing. I'm just warning you ahead of time. That's mostly because of my five made up characters: Kaori, Shiru, Hatori, Mizu, and Ramuki. I didn't feel like making a whole new story just to explain all that happens to them. I'll give you the short version (which is sort of long) of the story.
I highly recommend reading it. But it's your choice
I'll say this once: I do not own Naruto. Or Harry Potter.
The following story is just an introduction. I'm introducing the new characters and a few new events that happen before this particular story takes place. It will make you less confused.
A long time ago, there was a huge shinobi war raging between all of the countries. (This was back when there were more ninja villages than there are today. They disappeared slowly over the years following this war.) As the end of the war came near, The Light Village allied with the Leaf Village. No other village had made allies since no one could be trusted, or so it seemed, so this gave the Leaf and Light Villages an advantage. Other people realized this, and became afraid. Seeing how powerful the two allies had become, villages started allying with each other. The Leaf and Light Villages saw how powerful everyone else was becoming. The only village that hadn't allied anyone was the Sand Village, so the two allies attacked. Unfortunately, almost all of the other ninja villages had decided to attack that village as well, and on the same day. Everyone ignored just ignored whatever peace treaties they had made and just attacked. This battle, the last one, became to be known the Battle of Light. Why? Well, mostly because of Kakuzai Kiuno.
Kakuzai was from the Light Village. He was a strong ninja and the favored man to lead the Light Ninja into battle. He refused to lead, but he did fight.
The Battle of Light wasn't long. In fact, it only lasted for 3 days. On the third day, Kakuzai ran into the middle of the battlefield, almost dead, and let out an attack so powerful, the battle ended right then and there (Golden Light - Sky Shot). The Light ninja were thrilled. They had won the war! But as Kakuzai lay on the ground, dying, he made a famous speech.
"If I had the choice, I would have not let this war happen. In fact, not too long ago, I didn't even want to be a ninja. But I did not have a choice whether the war happened or not, as I was born into it. Curse those who let themselves be angered enough to rage into a war over their personal problems, over something much less than two little kids fighting for a toy. As for being a ninja, I've learned to love what I do.
"War is pointless. People die for nothing. We teach our kids to be nice to each other and solve our problems logically (if it comes down to a battle, then that's that). But war should never be a choice. No one ever wins, even if they think they have. Therefore, I believe that no one has won this war. Don't start complaining, my friends, because you know it's true. We've all lost more than we ever will in the future of our villages.
"I am not done yet. I also have something else to say." There was a long silence. "Every 1000 years, there will be another battle like this last battle, but in it all of the ninja villages will work together to fight against all evil. Ten battles will be fought over the course of ten thousand years. Ten battles. And ten chances for all of you ninja to restore your honor. The one who will lead you will be from my clan, the Kiuno clan, for I will be sure to pass down my knowledge of love, hope, truth, unity, and strength. I would hope that my children will do the same. I will handpick the ninja from my clan that I want to lead you. Now, if you win just one battle, you will have restored your honor and I will recognize you as true ninja, even in my afterlife. No more battles. But if you lose all ten. . .well, what happens after that will be for you to figure out. Rest assured, it won't be good.
"Goodbye, my fellow ninja. May we meet again someday."
And with that, he died.
His prophecy was known as The Kiu Prophecy (because, in the Light Village, the word 'kiu', short for Kiuno, came to mean 'great'). The ninja that he would handpick every thousand years was known as the Kiu Shinobi.
No one took the prophecy to seriously at first. Besides, what could a dead man do to them? But when the first prophesized battle actually came, people became a little more tense. He really was watching them, and he really was right. From then on, they began to prepare for these battles. They were sure they would win. How hard could it be?
But, 8 battles later, they weren't so sure. In each of the nine battles they had fought, they had been easily defeated. The Kiu Shinobi always tried his hardest, but the villages could never get along.
During the next thousand years, the villages started getting along better, and they began preparing for the last battle. They were more hopeful this time. Everything seemed to be going just fine.
But then, the Light Village disappeared. It was rumored that Kakuzai had taken them away, outraged by how badly the villages were doing (by now, most of the small villages had been destroyed). What really happened though, which the people figured out later, was that evil ninja had destroyed the Light Village and everyone in it.
The people tried to convince themselves that they could do it without the Light ninja and even without the Kiu Shinobi. But things started falling apart between villages and everyone lost all hope of winning.
Little did they know, Shitzu Kiuno had escaped the attack on his village and ran away to the Leaf Village, disguised as Shitzu Yukimura. He got married, had children, and became close friends with the Uchiha clan.
For a couple hundred years, things went perfectly fine. But then, the ten thousand years were almost up and the war was not far away. Sozu Kiuno, disguised as Sozu Yukimura, had three children, any of which could have been the last Kiu Shinobi. The first child, Nikoshi, seemed very powerful, but he was not it. The second child, Shiru, wasn't either. Not long after Shiru was born, though, Sozu got divorced. His ex-wife took Shiru with her, even though she wasn't supposed to, but left Nikoshi. Sozu was depressed for a while, but got married again. They had another child. Her name was Kaori. Sozu wasn't expecting anything from her, since all of the previous Kiu Shinobi had been boys. But, surprisingly, she WAS the last Kiu Shinobi.
He never told her who she was, so she lived a normal ninja life for a while. She was even friends with the Uchiha clan's children, Sasuke and Itachi.
When she was still pretty young, Itachi and Nikoshi destroyed their two clans and told Kaori who she really was. They thought they had killed her, but they hadn't. She decided to disguise herself as someone else and find a new home. She went to her half-brother, Shiru, for help.
Years later, she was on a genin team with Shiru and Hatori. (Hatori is sort of like a mix of Neji and Sasuke in personality.)
After a lot of adventures, which includes bringing Sasuke back from Orochimaru, Kaori's true identity was revealed by Orochimaru himself. Everyone was surprised, but they accepted it.
Not long after that, she was sent to our world (y'know, the boring, 3-D world that we live in) so that she would be safe until the great battle began. They would come to get her when it was about to start.
Unfortunately, Orochimaru came back to life (he had died that day when Kaori's identity was revealed) and he took Kaori back himself, along with two of her Earth friends. These two friends became ninja, and their names were changed to Mizu and Ramuki.
The battle was fought, and evil lost. Kaori had successfully led the ninjas through a terrible battle.
Months after that…well, that's where this story comes in.
A/N: Yeah, I know, it's long and confusing. It wasn't supposed to be that long, but it is. Sorry.
This was just an introduction. I'll write the real story in the next chapter.
BTW, if you want me to write out this short introduction as its own story, so that you know what really happened (ixnay the great war and Kakuzai's story), ask me. I'll think about it!
