Lightning Sage

They finally reached the village a week later with them carrying both Uzumaki most of the time to reach their faster but because they couldn't flicker it took quite some time.

At the gates of Konoha, they were stopped by the guards to ask about the two unknown people with them but with Jiraiya there they were able to enter without any problems.

They immediately head towards the Hokage tower and take the two of them towards the Hokage. Jiraiya barges in to find Hiruzen drowning in paperwork.

"Sensei, I have found something extremely important in Kusagakure."

Hiruzen looks up towards them and sees the red hair on the woman and child.

"These two are main descendants of the Uzumaki, they were living in Kusagakure."

Jiraiya quickly explained the situation to Hiruzen and how they were treated. Hiruzen nodded after the explanation and looked towards the two Uzumaki.

"Don't worry, now that you're in Konoha you are absolutely safe and don't need to do anything like that ever again."

"Thank you, Hokage-sama." Hisana said and bowed towards Hiruzen.

"It's okay, Anbu, take this woman to the hospital to be checked and get a house ready for her and her daughter."

An Anbu showed up kneeling "Yes." he said before turning towards The two Uzumaki.

"Please follow me." The two left with the Anbu.

"Raiden, please go with them." Jiraiya said to his student.

Raiden nodded then followed them to the hospital.

"Sensei, Danzo will definitely approach you about taking them into Root, how will you respond."

"It's okay, I'll turn him down for now with the excuse that the girl is too young and her mother is sickly."

Jiraiya nodded. "How is Kakashi's investigation going?"

Hiruzen sighed before saying "He really was hiding a lot from me. It seems what you said about working with Orochimaru was true, he has a kid able to use wood release. He also just took in a hundred orphans to train. Not to mention, He has hundreds of ninjas, most with a special technique."

"I'm sure he's hiding even more. Once Kakashi is done figuring who could be saved I'll infiltrate root and take a look at his records."

"Jiraiya there is one more thing. Your student's father, he has him. It seems he's under an obedience seal."

Jiraiya sighed "I thought it might be him, a Jonin suddenly disappearing after a successful mission? and when he wanted to retire in wartimes. He probably thought no one would pay attention and think he was ambushed."

"Don't worry, when Kakashi's mission ends, we'll infiltrate with the full power of Anbu and rescue them all."

"Sensei, when Danzo is captured I'll deal with the Uchiha. I'm sure their clan head realised someone is pressuring them and he knows who's want to do that."

Hiruzen nodded "You really should take over from me." He said.

Jiraiya said nothing and left.

After Hisana was checked up, she was admitted into the hospital so they can keep an eye on her for a couple of days as her body was very week and needed nourishment. Karin didn't want to leave her mother alone so she stayed with her.

Raiden headed towards his house to assure his mother nothing happened to him as they took longer than expected to come back.

He spent the rest of the day with her. Jiraiya later came and picked up Naruto.

The following day, Raiden went to the training grounds where he practices with Jiraiya to start working on the lightning chakra mode.

The lightning chakra mode works by having the user wrap their body in a layer of lightning chakra to increase their physical parameters, with more lightning causing greater increases. The lightning augments the strength of the user's taijutsu, creating what is called Nintaijutsu.

The lightning also defends the user from most attacks, deflecting them away on contact. The lightning chakra also stimulates the user's nervous system, enhancing their speed and their reaction time.

The user's reflexes are heightened enough to perform a Lightning Release Body Flicker, which is the level he wanted to achieve. With that, he should be even faster than Shisui. But it had one major flaw, it needed a lot of chakra for constant use.

Raiden had about Jonin levels of chakra that were extremely strong and he was only seven. He should have massive amounts of chakra by the time he fully m.a.t.u.r.ed which negates that flaw. He would even be able to make it more powerful.

Now his issue with training this Jutsu is that he still hasn't practised nature transformation.

Raiden first tried to use the Jutsu. He coated his body with his chakra and tried to transform it to lightning, but realised he couldn't do that to such a huge amount of chakra.

Jiraiya came to the training ground and saw this scene.

"You won't be able to use it that easy kid. this is a Jutsu that is dependant on both shape and nature transformation. It seems you have the shape transformation down pretty well, but you don't seem to have started training nature transformation."

"I have been training shape manipulation for a while." Said Raiden while withdrawing his chakra and turning to Jiraiya to listen to what he has to say.

"It looks pretty good, but you still aren't at the peak of shape manipulation," Jiraiya said while extending his hand and forming a blue spherical ball of pure chakra.

"This is the highest form of shape manipulation."

Raiden looked closely at the ball and activated his Sharingan to observe it. It was pure chakra with no element attached to it, compressed into a ball.

"This is the Rasengan, the Jutsu that was invented by the fourth Hokage, my student. It was modelled after the tailed beast bomb and took 3 years to make. Unfortunately, it still isn't finished. It needs extreme mastery of nature transformation to finish, but that would take a great amount of time." (Naruto was able to do it because he had hundreds of shadow clones working on it. If it was anyone else it would've taken years.)

"After you master this Jutsu, your shape manipulation should be perfect. then start training nature transformation." Jiraiya said. He started explaining how to train the Rasengan and gave him a balloon.
