So, this story will change very much from what I had originally planned.

I'll tell you what I was gonna do, since it would have been drastically different.

During Naruto's fight with Gaara I was gonna have Naruto unravel Gaara's seal and then he would seal the Shukaku inside himself, but in the same cage where Kurama was. There Kurama would eat the Shukaku and it would continue like that until all of the bijuu had been eaten by Kurama and he would become the 10 tails. Instead it'll go in an entirely different direction.

Just letting you know.

So, with that done. Let's get this story going!

"Uzumaki Naruto, we hereby promote you to genin. Here's your headband. Wear it with pride." Handing Naruto his headband, Iruka had a smile on his face as a 10 year old Naruto graduated.

Naruto also had a giant grin on his face as he put the headband on his forehead. Bowing towards Iruka, he left the academy behind him as he vowed to never return to that building if he could help it. The hours of wasted time always bothered him and he was happy to finally leave it behind.

Just the a month before, he had been able to achieve a 100% Hyoi Gattai.

Flashback

The reason that he had finally achieved a 100% fusion resulted in his change in conviction. Before, he only wanted to gain the title of Hokage to gain recognition and that was what prevented the complete fusion. However, he began to think about all of the people he had become friends with and all of the people that cared about him.

He had changed his conviction instead to become Hokage in order to protect all of the people dear to him. It was this change that allowed him to finally achieve the 100% fusion.

The difference between the 100% Hyoi Gattai and one that wasn't, was unbelievable. Even if the difference was only 1% the power difference and fluidity in movement was amazing. To Hashirama it felt that he was truly alive once more. To Naruto it felt like he didn't know which part of him was Naruto and what part was Hashirama. It was truly the perfect fusion of souls. Of course, once he did that with Hashirama he had to do that with Tobirama and Mito.

Once he finished using the Hyoi Gattai with them, he turned back to the book that had refused to let him advance. However, looking at it now, he knew why it didn't let him. If the oversoul was more powerful than even the 100% Hyoi Gattai then he would have been overwhelmed by the power and he wouldn't know what to do. But now he was ready.

Opening the book up, he saw the note Hao had written years ago. Flipping the page over again, he saw the notes on the Hyoi Gattai. Flipping over that page, he found that the once blank page was now covered in writing.

Reading through the new section he learned that an Over Soul was materializing a ghost onto the physical plane through a medium. An Over Soul actualizes the knowledge and memories of the ghost and allows their memories to be manifested in a physical sense. They are composed entirely of furyoku and as such conventional weapons are useless against them. The exact appearance of an Over Soul depends entirely on the users imagination, but it is also important to know that the medium the shaman uses symbolize the spirit's abilities.

He also learned that creating an Over Soul takes up as much furyoku as he puts into it and it doesn't take anymore to keep it in existence. However, it does take up furyoku when the Over Soul is either damaged or when it's used to create matter.

The final new pieces of information in the new section told him about Over Soul types. There were 5 known types of Over Souls used.

The first was the spirit type Over Soul which emphasizes the special powers of a spirit.

The weapon type Over Soul manifests the ghost in its purest form usually in a symbolic weapon form.

The armor type Over Soul is the pinnacle of Over Soul magic and are the most practical form of an Over Soul. They are highly impervious to attack due to the high density of furyoku and were just as strong in raw power.

The unity type Over Soul allowed for the shaman and the ghost to become one and the same. Both souls need to be in sync for the whole time that the Over Soul is used or it would break. This allows for both the shaman and spirit to use their abilities to their maximum.

The giant type Over Soul allowed one to create a giant version of their spirit in order to fight a much larger opponent. It allowed spirits to fight on their own using the furyoku of their shaman as their power source.

Reading through, he understood that in order to use an Over Soul to the fullest you must be able to achieve a 100% Hyoi Gattai not just for the power that comes with it, but in order to fully understand each of your spirits. This in turn would allow the shaman to make an Over Soul that would work best with their spirit.

Glancing up from his book, he could tell that his spirits were wondering what he had just read. Grinning, he told them he would show them, but that he needed to pass a test first.

Walking out of the Hokage Tower, Naruto had a giant grin on his face. When he showed Old Man Hokage and the two advisers that made up the Konoha Council just how skilled he was with the Raijin, they couldn't say no to him being allowed to use it in battle. They were reluctant obviously, but that didn't matter in the end. He had the Raijin and he would use it.

His spirits had followed him all the way to the tower and when he got back outside they followed him to the training ground were he practiced.

There he turned to them and made Tobirama turn into a hitodama, except instead of trying to fuse with him like usual he instead put him into the Raijin while envisioning the perfect weapon that Tobirama would be.

I know it's not much, but bear with it. I'm trying to get passed all of this beginning training, but also let you know about things happening. It's a pain I know, but oh well.

I'll talk about what happened to the oni later.

Naruto graduating early was my plan because I want him to be able to get some real experience using his shaman techniques before the main story begins.

Also, yes Hashirama's Over Soul will have the ability to use Mokuton. Just not how you thought it would.

Like always, review because I actually do care about what you say.

P.S. I took the Over Soul info from the Shaman King wikia
