Hanzo told his guards to take five for a moment so he could be alone with Naruto for a moment. This, of course, surprised them since he was never told them he wanted to be alone with someone. But they just shrugged their shoulders and walked away. It was just a kid with him after all.
"Naruto, I'm going to give you something special," said Hanzo. He then pulled out a scroll and then unsealed a much larger scroll and set it down while opening it up. "This is a summoning contract. Once you sign your name in it, you will be able to summon whatever creatures that the contract is with and they will fight with you. I would like you to sign the salamander contract."
"Really," cried an excited Naruto. Then he became confused. "Why me?"
"Lets just say that I think it will help," said Hanzo. "Also, you have skills that have yet to be tapped into. Until you do, the salamander clan will be able to help you out. They might even train you and show you some jutsus that you can use with them.
"Now, if you want to sign it you must sign it in blood."
Naruto went up to the scroll and did just that. It was a little sloppy, compared to the rest, but that didn't matter. When that was over, Hanzo showed Naruto the signs and then told him about the blood that was needed to perform this jutsu.
The next day, Sarutobi and Naruto were at the gates saying their goodbyes. Hanzo said goodbye to Naruto and then handed an object to Sarutobi.
"So what will happen to the Raijin?" asked Hanzo offhandedly.
"It will be placed back into the vault of my office," said Sarutobi. "There will be some new security features added to ensure that this won't happen again."
"A pity," said Hanzo. "A weapon should be used in the battlefield and not some safe. It would be a shame if it was never used again."
"Yes," agreed the Hokage. "However, if I did give it to one of the clans, the others would fight over it and say that I favored one clan more than the others."
"Then why not give it to a smaller clan or someone who doesn't have one," said Hanzo as he glanced at Naruto for a moment. "Then they couldn't do a thing about."
"Explain," said the Hokage.
"I know how arrogant some of the major clans in your village are," said Hanzo. "If you gave the Raijin to someone without a clan or is trying to build it up, you can say that you have the blade to them to help them along. Also, if any of the other clans fight or steal it, well it will be obvious and legal actions will have to take place regardless of their status. And, if they do steal it, it would be like admitting that they consider it a threat even if it is held by a nobody."
"Hmm, I think I get it," said the Hokage as he looked at the Raijin. "Well, we better get going." With that, Sarutobi and Naruto turned to leave. Of course Naruto waved for a while. Just before they were out of sight, Hanzo saw Sarutobi giving something to Naruto.
"The next generation will be very interesting indeed," said Hanzo.
