The Will of Fire.

Fujin.

Kurama and Pansa started cooking in the kitchen. They didn't udder a word about Naruto  again. Sasuke yawned and woke up. He looked to his brothers and went to the kitchen.
"So what are you two doing in Ash?" Kurama Ask
"We wanted to find the reason why my clan was annihilated, apparently I was a prodigy because I'm half Uchiha half Senju." Pansa looked at Sasuke, then to Naruto.
"We came to Ash and ran into my father Kenoshiro Senju." Kurama looked at Sasuke.
"He think he the father of Naruto and I. Because he slept with both of our mothers." Kurama dropped a knife and Naruto jumped up.

"Sasuke you okay?" Naruto said wiping is eyes. Sasuke turned around and looked at Naruto lovingly.
"I'm okay, Kurama dropped something, if you're sleepy you can go back to sleep." Naruto hummed and stood up. He walked to Sasuke and jumped on him. Legs wrapping around Sasuke waist. Arms slung around Sasuke Neck. He laid his head on Sasuke shoulder and inhaled his scent. Kurama chuckled and ruffled Naruto hair.
"Naruto How'd you unlock the Sharigan?" Naruto shrugged.
"I have just enough Uchiha blood in me, I don't know, it was dormant for awhile. Sasuke awoke his ten years ago." Naruto Said not moving from his spot.

"What's the plan with Orochimaru and Jiraiya. We seen them last night and said we forgave them that we wouldn't kill them but that you two would." Sasuke said sitting down because his legs was bout to break.
"We don't know, so let's train." Pansa Said happily.
"Yes Sasuke teach me Amaterasu." Naruto smiled and Sasuke couldn't deny him.
"Of course."

Sasuke showed Naruto how to active Amaterasu. Naruto smiled and showed him a better way to get his chakra to sync up. Doing quick handsigns he makes a small pool. He tells Sasuke to stand on the water and don't fall in. Sasuke scoffs and the water was like a raging water. They both trained and both were annoyed. Sasuke kept slipping after 3 minutes and Naruto couldn't get his Jutsu to active. Kurama went to Sasuke to help him and Pansa to Naruto.

"Sasuke, calm down take my hand." Sasuke did As he was told
"You need to constantly steady and change your chakra, but to do that you have to anticipate the way the water is raging. You have to find the perfect mix and when you do, your chakra will flow much better. Now try again." Sasuke nodded and tried again. Kurama smiled he was getting the hang of it.

"Naruto." Naruto looked up and sighed.
"I don't get it, I'm building up my chakra as well as my chakra in nature but it won't work."
"What are your Nature's?"
"Wind, Water and Fire."
"Which one are you tapping into?"
"Fire, but it isn't my strongest affinity, I can only do B-rank with Fire and S-class with my other two."
"So it might be because your fire isn't your strongest try wind." Naruto takes a deep breath and opens his eyes.
"Fujin." Naruto whispers out and the area around the tree literally make wind scythe and the tree gets sliced.
"So that's your Amaterasu only with wind, so I guess it'll be Fujin." Naruto like it. It isn't cool Fire like Sasuke, but you can barely see it you can only detect it which is a plus.

"Sasuke how are you doing." Sasuke looks up and waves Naruto over. Naruto stands on the raging waters with Sasuke immediately getting accustomed to the water. Sasuke took Naruto hands and started walking to get a better feel of the water.
"It's going, it hard adjusting to all this chakra." Naruto laughed.
"Yeah I had my Uzumaki chakra which was already a shit ton on top of Kurama's chakra, I'm surprised I was able to learn any jutsu lower than a B." Sasuke chuckled.
"How is your Amaterasu training." Naruto pouted. Sasuke saw that and smirked.
"Fire isn't my dominant chakra in nature so I have to train to enhance it like my wind and water. I was able to do it only with wind. So it's called Fujin instead of Amaterasu." Sasuke nodded and Naruto let go.

"Naruto."
"It's your last part of this training, Jiraiya did this with me." With an Hand signs the little pool took up the backyard. Sasuke looked confused until Naruto spoke.
"Catch me before dinner and not only would you sync all of your chakra I'll give you a present." Sasuke raised an eyebrow.
"Which is?" Naruto smirked
"Me obviously." Naruto made the waters a little more difficult and ran away with an Uchiha hot on his trail.
