Saga of the Shadow

Plot
Hikaru Kurosaki is a ninja from the lost lands searching for Naruto Uzumaki. He was sent by his leader in the Village Hiddden in the Crystals. His people were taking refuge there because Kagegakure 2 was overtaken by the Time and Wood villages.

Meanwhile, Naruto became a Chunin after defending the hidden leaf from a horde of Rain ninja sent by Pain. Later that night, he had a dream of a wolf-like creature telling him he must help "them", whoever they are.

Hikaru later arrives near the gates of the hidden Leaf, but he is ambushed by some Time Chunin that were tailing him. He is almost finished, until he unleashes an unknown ninjutsu, killing his enemies instantly, but at the cost of whatever stamina he had left. He is later found by Sakura and taken to Konoha Hospital, unable to heal him on the spot.

Naruto hears of the news of Hikaru, and rushes to the hospital, remembering that his dream told him of a ninja named Hikaru. He meets up with Hinata and Kiba at the hospital. They told him they were called to examine Hikaru's belongings and see if they could trace him to his homeland. Unfortunatly they were unsuccessful. Hikaru wakes some time later to tell of his origin and his home. He tells them that he is the great-great-grandson of Madara Uchiha's Brother. He then tells of how this is possible.

His great grandfather, Rai Kurosaki Uchiha, decided to leave the land of fire before the Leaf was even formed. He took along some Uchiha and Senju Ninja to start their own land. Sakura says that how come it was never in the Leaf archives. Hikaru said that not even Madara Uchiha himself knew of these events. He then tells that his great grandfather was only 14 at the time, but he was respected just like his uncle. At the time, Madara Uchiha and Hashirama Senju were fighting over who would be the leader of the village, so this was the perfect chance to escape.

Hikaru is doubted by everyone there except Naruto. He said that somehow, he said that Hikaru wasn't lying. Hikaru then tells of the Legendary Ten-Tailed Wolf. Sakura says that only 9 bijuu existed, and how could there be a tenth. Hikaru explains that Zukia Tojiro created somewhat of a ruler over the bijuu. Madara was never even told that the Ten-Tailed beast existed. The Ten-Tailed Wolf is also very kind hearted.

With all this information told, he then asks if Naruto would come to help him defeat a villain from Naruto's past that is stronger then what he used to be.
