Naruto Of The Rinnegan

Itachi

As Naruto arrived to the training ground, he saw Sasuke getting ready with Kakashi, Hinata and Gai.

"Where are yall heading without me?" Naruto asked.

"Itachi told young Sasuke here where he could find him and Kakashi found out so he asked us to accompany them despite Sasuke not agreeing." Gau ranted.

Sasuke clutched his sword handle and his mangekyo activated.

"I'm going too." Naruto said.

"We guessed." Hinata mumbled back as she gave him his sword.

Naruto smiled before they all took off.

"Where is he?" Naruto asked.

"An old Uchiha hideout. Kakashi, Gai Hinata and you are going to take care of his Akatsuki partner while I whipe the floor with that nasty blood of his." Sasuke spat.

Naruto nodded slightly as they continued.

They arrived and Naruto held Sasuke's shoulders.

"Let me help you." He mumbled.

Sasuke was about to reject until he felt chakra pumping into his body.

"You won't allow me to fight, so use this extra chakra to take him down. I'll remain behind to watch while my clone helps them." Naruto spoke.

Sasuke let out a sigh before he left and went to the building.

Naruto's clone and allies all went to face Kisame and the moment the clone had the chance to touch him, he teleported them all away.

Naruti stayed behind not doing anything knowing when the right moment to step in was.

He heard the 2 battle using taijutsu then later on discussing the mangekyo while the 2 flashed their personal mangekyo abilities.

He also heard mentions of his grandfather Madara and that the mangekyo would progressively lead to blindness.

Itachi also revealed that the only way to stop the blindness was to take the eyes of another Mangekyo Sharingan user; he stated that this was the reason he had left Sasuke alive, and why he had pushed him to become stronger

The fight went on for more time with both giving all they had to offer. After a long time the 2 started their fight on the rooftop.

It began to rain, and Sasuke said that this new technique was unavoidable. Naruti guessed it was the new jutsu the Uchiha was working on yet not telling anyone.

Sasuke charged his final technique, Kirin. A huge creature made of lightning appeared, fuelled by the Great Dragon Fire Technique which had dumped a huge amount of residual heat into the upper atmosphere, and Sasuke's chakra remained suspended in a usable form, changing with the atmosphere from simply fire chakra into a bolt of lightning characterised in the same form as the earlier Great Dragon Fire Technique, but cast instead from lightning.

Naruto stared in shock both cause of the jutsu and the thought behind it and the plan that Sasuke followed.

Sasuke smiled in confidence before the smoke cleared showing itachi in his susanoo.

He continued attacking his brother using various jutsu and spamming his mangekyo to the point he could barely see from afar.

Giant snakes suddenly appeared out of Sasuke. One of them revealed Orochimaru inside its mouth. Sasuke, having used up nearly all of his chakra fighting Itachi, could no longer suppress Orochimaru.

The snakes were all killed, and Orochimaru was stabbed by the Sword of Totsuka ,which itachi had with his susanoo , sealing him in an eternal dream state. Rhe remains were subsequently sucked into the Sake jar that the Sword of Totsuka was sheathed in.

Itachi then asked Sasuke if that was all he had. Sasuke then proceeded to attack Itachi, again ending in a futile attempt as all his attacks were reflected by another effect of Susanoo, the Yata Mirror, which reflected all attacks directed at Itachi.

Sasuke was knocked back by his own attacks, and laid on the ground. That was when Naruto knew he had to step in.

Itachi walked towards his brother, seeking his eyes which terrified the younger Uchiha

When Itachi reached Sasuke, he poked Sasuke's forehead, saying, "I'm sorry, Sasuke. There won't be a next time." Leaving the man confused.

"There will." A voice said.

Sasuke fell to his knees exhausted yet still conscious.

Naruto's rinnegan activated and he sat next to Itachi.

White flames appeared on Itachi's body as the man screamed in pain.

"H-he's... mine t-to kill." Sasuke stuttered.

"No one's killing him." Naruto said.

Bt the time the flames distinguished, Itachi looked perfectly fine.

He stood up and stared at Naruto, feeling brand new.

"H-how." He stuttered.

"You 2 aren't the only ones with amazing mangekyo abilities. Why have fire that can burn everything when you can have one that does the opposite and heals everything." Naruto spoke as he healed Sasuke.

The younger uchiha stood up and rushed at Sasuke to attack him only for Naruto to restrain him.

"Explain everything to him, it's pointless now." Naruto said.

Itachi let out a sigh before Naruto left the compound for the brothers to catch up on everything.

He waited outside the compound for an hour until the brothers walked out together.

"He wanted to destroy konoha, convinced him to only kill Danzo tho." Itachi said as he pointed at his brother.

Naruto nodded before he felt a sudden chakra signal. He jumped and rushed to see where it cans from and saw a weird black and white creature.

"What are you?" Naruto asked as he let out his sword.

"I'm zet-" his speech was cut short by Itachi setting him on fire.

He seemed to immediately decompose.

Itachi fell to his knees as he held his eyes in pain, Sasuke also seemed dizzy with the amount of times he used his mangekyo so soon after unlocking it.

"We'll have to fix that." Naruto ordered
