In the kitsune society, power and cunning is everything, a kitsunes power can be measured by the amount of tails they posses, starting with one or two at the time of their birth, gaining more as they defeat other beings, the stronger the enemy they defeat by using power, cunning or both, the closer they come to getting a new tail and be able to rise in their society.
The strongest kitsune alive today is the eight tailed Yamaru, who took over after tricking the former lord, nobody in the kitsune realm knows what happened, after a dispute over politics the two entered a forest to fight, only Yamaru left. Nobody had expected Yamaru to win, since the old leader had been so powerful.
The former lord was only known as Kyuubi, the nine tails, the only kitsune to have had nine tails in over five hundred years. It was said that there could only be one kyuubi at a time so with the old one assumed dead the many kitsune began to fight anyone and anything they could in hopes of becoming the new kyuubi.
Twenty years have past, and the kitsune tribe is in a bad situation, many kitsune had died in their quest for power, and many other youkai are angry at the kitsune, as they wandered the youkai realms in order to find worthy opponents and they attacked many other youkai tribes.
But even as the world turns against them, even as Yamaru tries to reign them in, they continue to strive for power.
Ten years before present time. At a dojo in a kitsune village.
A small girl no older than 6 grunted as she smashed against the dojo wall after her sparing opponent had casually thrown her into the air.
"Looks like I win again Naruto no baka." A young male said to his defeated kin. "Like a one tail or a half blood like you could ever dream of beating me , the great and powerful Kuyou!"
"Just you wait Kuyou, one day I'll beat you, no matter how many tails you have." Naruto said angry.
"You hear that." Kuyou told the other kitsune. "The mutt thinks she can beat me." The other young Kitsune laughed. "Accept the fact that you will never accomplish anything ad will as most be a servant girl to me and my subordinates. The loser has to clean the entire dojom that was the condition of this fight, so get started. Guys do it." The other kitsune went outside and soon returned with buckets. In a few seconds the dojo was filled with dirt and grime.
"Don't be lazy, I want to be able to see my reflection on the floor by tommorow." Kuyou said before leaving the dojo with his cohorts.
Naruto looked over the scene of her defeat. Tears bearly held back she repeated a mantra in her head. 'One day I'll show them, One day I'll show them.' Fire returned to her eyes.
"One day I'll show them all!" She said out loud. "One day." She said before starting on her task, she had after all given her word, and her word was her soul.
Present time.
Not to far from Yokai academy a young sixteen year old girl stood observing the place where she would grow in strength and the place where her most hated rival lived. Her long blond her moved by the winds will and in her blue eyes there was a unshakable resolve.
"Kuyou, prepare yourself for an ass-kicking." Naruto said to herself before walking to the school with confident steps.
Authors note:
Just a small idea I had about the possible characteristics of the kitsune race and how Naruto could fit in in the Rosario+vampire universe. I don't know if I'll write any more of it, but if anyone feels inspired feel free to write it.
