First of all, Seiashi is replacing Konoha. No canon characters are being used. These are all original characters created by me. This story will have 7 main characters, however it will be in the omnipresent view point of three of them.
Disclaimer: I do not own Naruto or it's characters. I am just using the ideas for my fanfic.
The day shone bright on the village of Seiashi as the mist spread over its very being. The tall building in the center was the only one safe from the engulfing mists. Seiashi, the village hidden amongst the spirits was known for the mist that spread from its forests and covered the village in such a dense fog that only the villagers who had grown up in it could see anything in front of their faces. The eyes of the people who had grown in the village of Seiashi had developed a special bloodline trait to help them with the fog. Their eyes could see through any mist, whether it was chakra laced or not. It is within this village that the story of a great shinobi was born. This shinobi was named Kakashi Kimura.
Kakashi Kimura was a very special shinobi. His bloodline was rare throughout the village, one that only happens once every few hundred years. This bloodline trait allowed for five bodies and five souls are interconnected. It is known as the Pact of the Five Flames. It is named such because of the original user of the trait. The first user did not have it as a bloodline trait. Instead he had made a pact with four other beings and fused themselves together. This pact fused itself with his blood and thus became a kekkei genkai, however it is a unique one in that once the original user has died, it can take hundreds of years for the next user to appear.
Kakashi Kimura was the first Pact of the Five Flames user for five hundred years. He had no one to learn from and no one to experience the training from. To make matters worse, his parents were murdered by a former family friend. Kakashi was brought under the tutelage of the Seikage, Zap Fosho, and his beloved wife, Karite Akumu. The two of them gained a false immortality through the ancient Akumu rituals and have taken care of the village for 500 years and were the only ones to have met and spoken with the last user of the special bloodline trait. The two have cared over Kakashi since he was little. The two have made sure that nothing else has tortured his soul and are trying to him master the technique.
Kakashi has grown up in a village where no one knew much of the technique and knew not whether to fear it or love it. Some don't even know the technique and think he is completely insane. They think that when he talks in the various voices, that he has completely lost any sanity and that only the Seikage can prevent him from killing anyone. The Seikage has tried to educate others on the technique, but only the shinobi have even remotely understood, and even then, some are extremely confused.
The story of Kakashi Kimura, his friends, and loved ones is one of turmoil and destruction. Nothing will go as it seems and the turmoil of Seiashi will show the rise of true heroes. Will this be Kakashi's finest hour or his greatest failure?
