Fixing Kakashi's Sharingan.

The next day…

Minato had called the Anbu Black ops to his office both Ryuu and Kakashi attended.

"Many shinobi from small villages survive by taking advantage of the turbulent situation, they have no wish to be controlled by the lands of fire, wind, or earth, so I have no doubt they'll continue to cause disruptions.

However, this peace was made through the sacrifices of others, so we must maintain it, and for that, I'm going to count on all of you."

"Yes, sir!" They all responded.

The other Anbu members left the room, leaving only Ryuu, Kakashi, and Minato.

Kakashi left after confirming he wasn't needed.

"I've been meaning to talk to you about something." Minato nodded.

"Now that the war is finally over, I can focus on other things, for example, I want to go to search the ruins of Uzushiogakure for a couple of months.

I want to expand my knowledge of fuinjutsu but I haven't had the chance to do so.

I want to stay here for a few months just to be there to support you." Minato nodded.

"I see… I'll think about it, but you should know, leaving the village for months won't be easy on us, but as long as you'll come back soon, I have no worries."

Ryuu nodded and left.

He followed Kakashi, who was practicing Chidori and purple lightning in the training grounds.

He struck the wooden dummies with his Chidori and destroyed them, and then he switched to purple lightning and did the same.

After training, they went to a watchtower.

"Five shinobi, they're from Iwa!" a jonin said.

"Don't we have a peace treaty with Iwagakure? Maybe they're here for some business." Another added.

The shinobi threw their shurikens towards the jonin but missed; they attacked them with kunai.

"Why are you breaking the treaty?" He asked.

"Hey, we're Shinobi from the leaf village." The other one added.

"Stop, maybe there's a misunderstanding."

Five Iwa shinobi surrounded them.

Whoosh! 

The Anbu Black ops appeared, throwing shurikens to warn them.

"Reinforcements, retreat!" They left as soon as they saw the Anbu members.

"Thank you, looks like Iwagakure has betrayed us." Ryuu shook his head and picked up a shuriken.

"This isn't an Iwagakure shuriken."

"You mean they were fakes? But why would…"

"To cause a rift with Iwa."

Whoosh!

Kakashi chased after them.

"Excuse me." Ryuu disappeared and followed Kakashi.

He had activated purple lightning and hunted them down.

"One." He counted them down as he struck each of them with his purple lightning.

The last one remained, he looked back and saw Ryuu and Kakashi following him.

He tripped and fell on his back…

Kakashi and Ryuu stopped and landed near him, removing their mask.

He was trembling in fear.

"The Sharingan, you're the infamous cold-blooded Kakashi, and you're the shinobi Scourge, Ryuu Uchiha."

Kakashi charged up his Chidori.

"Kakashi wait!" The other two Anbu members were close by.

"Somebody help me!" He screamed.

"Five!"

Kakashi directed his Chidori towards him.

Boom!

Ryuu directed his hand away.

"Why did you let him go that far?"

The Anbu asked.

Ryuu and Kakashi glared at them with their Sharingan, it sent chills to their spines.

Later that day, Minato summoned Ryuu to his office.

"You called for me?" He nodded.

"Well, I have some good news I'd like to share with you." Ryuu nodded.

"Kushina is pregnant." Ryuu's eyes widened.

'Naruto.' Ryuu said to himself.

"Congratulations Big brother." He smiled and nodded.

"I've assigned Kakashi a secret errand for me, to protect Kushina from all dangers. I hope this will help him, I've heard he can be quite difficult to work with."

Ryuu nodded.

"That's true, after the incident with Rin, he trained himself to be merciless without hesitation, especially after the first mission he did after you became Hokage."

Minato nodded.

'That reminds me, I have to fix Kakashi's eye.'

"Umm, big brother, I have to go. I have an important task to do." Minato nodded.

Ryuu teleported and went to Orochimaru's lab.

"Orochimaru, I need a lab for an experiment I want to conduct."

He nodded.

"Follow me." Orochimaru led Ryuu to a lab below his current one.

"What experiments are you doing?"

"The kind that'll use Hashirama cells," Ryuu replied.

Orochimaru nodded.

"You're trying to fix your friend's Sharingan." Ryuu nodded.

"I may need your assistance." Orochimaru nodded.

"It's been a while since we worked together, maybe we can pick something up from one another." Ryuu nodded.

Ryuu took out a large scroll and placed it on the table, he formed a hand seal and it released a White Zetsu body.

'Not only did I steal this from Madara and Obito, but I also destroyed information on how to use Hashirama cells to their full extent.

Madara hid some of these, but I can sense the incredible vitality from Hashirama cells, plus I've been storing them ever since he took me in.'

"Orochimaru, this process will take a while. Are you sure you're going to stay here for that long?"

"What's the point of missing this? It's obvious you have something planned, I'll stay here and learn from you."

"Alright, let's get started."

Ryuu teleported to Kakashi.

He was sitting alone, watching the river flow past him as Guy and the Kurenai had a conversation on a nearby bench.

Behind a tree, someone was staring at Kakashi, she had light blue hair, with a ponytail pointing to her right, her eyes were red and she wore a short dress reaching her knees, and wore long socks that covered her legs.

"Kakashi, someone is staring at you, do you know her?"

Kakashi nodded.

"That's probably Mina."

"Mina?"

"Yeah, she's new in the village. She followed me all the way here after I saved her from some bullies on a mission."

A sly smirk appeared on Ryuu's face.

"Would you look at that, Kakashi? I always knew you had it in you." Ryuu winked.

"I don't know what you're talking about."

Kakashi replied while closing his eyes.

Ryuu chuckled and covered his mouth.

"Anyway, you got a sec?" Kakashi shrugged.

Ryuu teleported to Orochimaru's lab with Kakashi.

"Ryuu, what are we doing here?"

"Your Sharingan is hindering your growth. I brought you here to fix that problem, I can't let you be so weak." He nodded.

"Just lay down here and trust that I can help you." He did as he was told and laid down on the bed.

"Ryuu, these cells aren't the same as the ones I had, they aren't the same as any I've ever seen except the White Zetsu you brought to me." Ryuu nodded.

"They're weaker Hashirama cells but a little stronger than the White Zetsu cells, I did a lot of experiments and tests to perfect this." He nodded.

For seven days Ryuu would inject the cells into Kakashi, he knew nothing about what he was being given, only that it was affecting his chakra and eye.

'It's absorbing the Hashirama cells well, I figured this would work, from the beginning, Senju and Uchiha share the same roots but the Senju bloodline were made to Suppress the Uchiha powers, that's why they defeated them during the warring state.'

Naturally, the chakra approached Kakashi's eye and that would make the Sharingan believe it was threatened, but this would make the eye resort to Kakashi's body, and in return that would lead to it using less of his chakra over time.

After a few days, Kakashi's optic nerves were filled with the special chakra released by the Sharingan.

"Kakashi, get up." He was reading a book.

"What?"

"I want you to try controlling and activating the Sharingan.

I don't expect it to work immediately, but after a couple of tries, you should be able to do it." He nodded.

After 30 minutes of trying, the crimson three tomoe pattern finally faded and his eyes went back to normal.

"Great work!"

'He attempted activating it and it worked, consuming far less chakra than before and because of my enhanced Hashirama cells, his chakra was increasing too.'

"Ryuu, how did you do this? When I'm using it, I can feel my chakra being restored. Is this the result of the cells you used?" Ryuu nodded.

"I told you I could do it."

Ryuu said with a proud smile on his face.

Kakashi and Ryuu left Orochimaru's lab and went to training ground three.

"Minato?" Ryuu sensed his chakra nearby.

"Minato-sensei is here?" Ryuu nodded.

He appeared behind Ryuu.

"Are you skipping your Hokage work?" Ryuu asked.

"No, no, that's not it, just cause I'm Hokage doesn't mean I have to forget about training, if that was the case I wouldn't be able to protect the village." Ryuu nodded.

"I just came here to try out a new jutsu I've been secretly working on, I knew you were here and wanted you to help me out." Ryuu nodded.

"Stand back." Ryuu and Kakashi moved back.

"Shadow clone jutsu!" He made a clone.

'I see, he's trying to make the Rasen-shuriken and needs the clone to add wind style.' Ryuu made a Rasengan.

"Minato, if this jutsu works, then my Rasengan should be useless, right?"

He nodded.

"In that case, let me help you create this jutsu, I'll heal us later."

"Alright, get ready." Ryuu nodded.

He added wind style using the clone.

It had a chilling screeching sound, and it was turning light blue and whiter.

"Alright, here goes nothing!" Ryuu and Minato ran at each other.

Boom!!!

The ground shattered, and the wind blew hard from the impact…

'My… hand…' Ryuu's hand was trembling on its own, the damage caused was severe.

He activated Phoenix Flame, and it healed his wounds.

"You almost had it," Ryuu said to Minato as he healed him.

"I still can't throw it yet, the amount of chakra I'm using makes it too heavy and the damage I receive from it is too risky, I have to find a way to make this jutsu properly."

"Well, I have an idea, what if you use your chakra in the very last second to gain enough strength and launch it."

Minato's eyes widened.

"You're right, that should work!" He got up.

"Let's try this again."

Kakashi stood further this time.

"I'll try it with you." Ryuu made a Rasengan. He added wind style to his Rasengan, and it grew larger and whiter. It made a screeching sound just like Minato's.

"Alright, now!" They threw their Rasen-shuriken…

Boom!!!

Two enormous explosions occurred.

Whoosh!!

The sound of the wind blowing things away sent debris towards them and that made Minato and Ryuu teleport to where Kakashi was.

'It's more powerful than I thought it would be, it's like a tailed beast bomb.' Ryuu stated as he looked at the massive crater created by the jutsu.

The training grounds had two massive holes that made them look like craters.

"Incredible."

Kakashi said as he looked at the training grounds which was in ruins.

A giant crater was created by the two jutsu's.
