Ishizu POV
After I left Sasuke, I went home and had a good sleep. Unfortunately, my sleep was interrupted when Naruto burst into my house.
"Sensei, we need your help. Sasuke left the village! We need you to come with us." I was still in my bed and being separated from my sleep was not good so I fell asleep again.
"Come back later," I murmured, not realizing what Naruto said, and honestly I didn't care.
General POV
An annoyed Ishizu was dragged to the Hokage office by a blond boy.
"Why can't Ishizu-sensei be coming with us," asked Naruto as they stood before the new Hokage Tsunade Senju.
"Because I can't afford to send more Jonin out of the village. Shikamaru made a team with the objective to find Sasuke Uchiha and bring him back. A Suna team was also sent out to help you. Now go!" said Tsunade.
Ishizu was happy as he didn't want to help the Genin fight. They needed that to grow stronger and he wanted to sneak out of Konoha while a wood clone stayed here.
No way would he miss this opportunity. Ishizu has to make sure that Sasuke was safely 'delivered' to Orochimaru.
The retrieval team left Konoha and Ishizu followed behind them. He watched the first interaction between both parties. The big guy stayed behind while the rest continued while Choji stained behind.
Ishizu left with them knowing that Choji could win the fight.
After that came Neji and spider guy.
The teams comprised Tayuya and the two face creep, while on the other side were Kiba, Shikamaru, and Naruto.
Ishizu only remembered Tayuya's name because she had red hair and maybe she was an Uzumaki.
Worth saving Ishizu guessed, if only for being his underling.
Orochimaru should already use his new vessel so he couldn't take Sasuke's body. The fights went on and Kiba and two face creep fell somewhere to fight alone. Kimimaro arrived and took Sasuke with him.
Naruto followed the Kaguya while Shikamaru fought Takuya. Ishizu made a clone to prevent her from dying. Her curse seal was not a strong one, so taking it away and some improvised Talk no Jutsu or mind-altering could make her his follower.
On the grass plain Naruto confronted Kimimaro. Ishizu was excited to see how his student could fight against the Kaguya boy. In canon, Naruto stood no chance. Even Lee couldn't win.
Only Gaara could defeat him and only because Kimimaro was already with one foot in the grave due to his immune disease. Now a much stronger Naruto stood before the ill Kaguya.
As Naruto was more m.a.t.u.r.e, he didn't get angry and let Kurama's charka help him. No, he attacked the bone boy straight up.
"Kage Bushin no Jutsu," shouted Naruto.
A smokescreen and out of it came a hundred Naruto's which attacked simultaneously Kimimaro. Kimimaru didn't expect so many of them and went into stage 1.
With that, he used his bone dance, destroying the clones.
"We are not finished, Rasengan!"
The real Naruto came out of the smoke with a Rasengan in hand. Kimimaro didn't think taking the attack head-on was a good idea as he created a massive bone shield to counter the attack.
"You are strong. Too strong to let you live for long. I don't have much time," said Kimimaro.
Ishizu wanted to see more, but it looked like he had to move as he felt Lee coming closer to Naruto and also because the Pot was opened from the inside.
Ishizu POV
'My time to shine.'
I put on my fake Otogakure headband and jumped to the pot. It confused Kimimaro at my sudden appearances as I was very fast.
"Orochimaru-sama send me to retrieve his vessel. He wants to say that you were very useful to him Kimimaro-san."
Kimimaro couldn't do anything but to agree to trust my fake headband.
"Hey what are you doing? Give Sasuke back!" Naruto attacked.
Ishizu took Sasuke out of the pot. "Finish it Kimimaro. Make Orochimaru-sama proud."
Sometime later
"Let me go! I can walk by myself," shouted Sasuke as I carried him.
"Be quiet. I need time to apply the seal and I don't want anyone to interrupt me," I said without looking. Sasuke realized that it was me so he kept quiet.
"My seal did what it should do. You didn't reach stage 2 but still got stronger. I would advise you to use the seal only when nobody is looking. Even if Orochimaru finds out that it is not working, and I doubt that, he won't do anything to acquire your wrath. He still needs you."
We reached The Valley of the End. In all my life in this world, I never had the time to visit this place.
Those magnificent statues of the two strongest people stood across each other.
On the right side, a man who was called the God of Shinobi. One of the founders of Konohagakure and husband of the first Kyuubi Jinchuriki. A master of his famous wood style and Asuras reincarnation.
His name: Hashirama Senju.
On the left side, the strongest Uchiha who has ever lived. The patriarch of the Uchiha clan and Indra's reincarnation.
The one who could use his eyes to capture the strongest of the bijuu and take him under control. He who fought against Hashirama but lost but didn't die.
The man who acquired the famous Rinnegan and even now his presence is seen in the world.
His name: Madara Uchiha.
"Here we are. This place is truly amazing."
We made our way to the Madara Uchiha statue.
Sasuke looked and saw two statues facing each other.
"What is this place and who are they?" asked Sasuke.
I smirked: "That, my dear Sasuke, is The Valley of the End and these two are the founders of Konohagakure, Hashirama Senju, and Madara Uchiha."
Sasuke's eyes widened and the mention of one of his ancestors.
"Now stay still. I need to place my seal. Fuinjutsu: Nature's Calm." With that finally, the seal lost its original function and was only a reservoir of Senjutsu. Before Sasuke could leave, I saw Naruto running to us.
"It seems like my other student doesn't want you to go, Sasuke. A bummer that he will face me."
Sasuke looked at me.
"Why?"
"Hmm?"
"Why do you do some much for me? You betrayed Konoha and even want to fight Naruto so I could gain power. What have I done to deserve it?!" cried Sasuke.
I smiled as I patted his head.
"Because you are also one of my students, and I will do anything to make them happy. If the means to betray Konoha and fight my other student, then so be it." Sasuke cried a little and started to walk away.
"Hey, Sasuke, you won't leave. I will bring you back to Konoha! How dare you leave your Sensei and your friend behind?"
I walked in front of Sasuke.
"Go, I will handle him."
Oh, that is going to be fun. Facing a furious Uzumaki is difficult, but this was but a boy, unlike the two women.
Only better than last time.
Naruto and I hit our arms against each other, a gesture to measure one's strength.
"Naruto Uzumaki and Jinchūriki of Konohagakure. I will not let you near the vessel of Orochimaru."
Naruto's eyes were starting to get red.
"If you hinder my path that I will walk over your corpse and I will drag him back."
I smirked under the mask.
"Hard words for someone so young. Show me your strength! My name is Yamamoto Kansuke, the Wood God."
The battle between Yamamoto Kansuke and Naruto Uzumaki started.
General POV
Ishizu didn't remember a lot about the canon fight, but one thing was still in his memories. That annoying plant would watch it from somewhere safe.
He couldn't reveal his Rinnegan or the next time Ishizu would have to face a mad self-proclaimed god and a brainwashed Uchiha. Fortunately, Fuinjutsu was his friend.
'Dragon>Horse>Tiger>Hare>Monkey>Boar> Tiger>Snake.'
"Fuinjutsu: Reality warping."
It was a special type of Fuinjutsu that Ishizu had invented during his studies with Mito.
A Fuinjutsu mixed with Genjutsu.
It created an illusion for outsiders to watch what the user wanted as long as they don't enter the reality bubble.
With that, Zetsu would be fooled thinking it was Sasuke who fought Naruto and not Ishizu.
Naruto and Ishizu clashed.
"You have a long way to go before you can match against me young Uzumaki. I have faced other Uzumakis and you are by far the weakest."
Naruto summoned numerous Shadow Clones to overpower Ishizu.
"I will defeat you. You won't be able to get Sasuke!"
Ishizu smiled, Rinnegan shining behind the mask as he pointed his right hand at Naruto.
"Shinra Tensei"
The invisible force rushed at the clone, blowing them away.
'The chakra drainage is much better. The training helped me a lot,' thought Ishizu.
Ishizu had to dodge a kick as he grabbed Naruto's leg and slammed the boy into the water.
"You are a fool if you think you can just drag the Uchiha back to the village as nothing happened. It is not that he cannot go. He must or he will die."
Ishizu jumped away as the massive chakra erupted from underneath.
Naruto dragged himself onto the water; his eyes were red and Kuruma's chakra was leaking from his body.
"Why should he die? He has us to protect him! Everyone who challenges me will fall!"
The blond boy charged at his sensei.
His fist got blocked by Ishizu, but the Rinnegan wielder felt the power increase as he was flung several meters back.
"A curse is not something companionship can erase. He had to sacrifice himself to save his friends. The power gain is just his misguided belief to kill his brother.
I am only supporting Sasuke Uchiha because it needs to be done," explained Ishizu but Naruto didn't want it to hear it as he again attacked Ishizu with a roundhouse kick.
Ishizu block crossed his arms to block it, smiling underneath his mask at the power the boy had.
Then he punched Naruto in the stomach to send him back.
Coughing for a second, Naruto again stood up feeling as the foxes chakra kept getting stronger.
'More. To defeat him, I need more!' mentally shouted Naruto.
"Don't you tell me what to do. I am giving you as much as I can. If I give you too much, you will lose control you idiot human," shouted the Kyuubi.
Naruto stood up as he glared as his enemy.
He didn't care if he would lose his sanity. Nobody would stay between him and his friends.
Not even Yamamoto Kansuke the Wood God or any other God. He would defeat them all.
"Then I will go with Sasuke and kill that bastard of a snake. How dare he do something to him? Let me go!"
Seeing his enemy shack his head in denial Naruto only had one thing to do.
A burst of chakra came from Naruto as he went into 2 tails mode.
"This is as far as I can help you without you losing your sanity so make the most of it," spoke Kurama.
'Damm, this kid got strong fast. I think I have to calm him down or he will destroy the reality bubble himself,' thought Ishizu.
Naruto ran at his sensei, but the latter took his time in blocking the rage-filled blows before grabbing Naruto's arm and throwing him into the Hashirama statue.
A burning sensation got Ishizu's attention. His hand with which he grabbed Naruto was red and blisters were forming.
'His chakra is dangerous. I should avoid getting hit by it.'
"You should take some time and relax. This much chakra is bad for your health. Let me help you with that fox problem."
Ishizu made hand sight. A jutsu that would counter Kurama's chakra.
"Wood Style: Wood Dragon."
A dragon emerged and flew towards Naruto.
It was rather small compared to Hashirama's massive one, but Ishizu was only starting to use the Wood Style.
That also meant that it had not the d.e.s.i.r.ed effect. When the dragon surrounded Naruto, trying to drain him from his chakra, a clean cut was seen as the blond boy broke out of it.
"Yamamoto, give Sasuke back!"
The voice of Naruto was almost that of another person. An indicator of him losing control over Kurama's chakra.
A claw stretched out to grab Ishizu, but he used another Shinra Tensei to send it back.
More and more arms came from Naruto aiming to kill.
"I think you are losing your control, Naruto. I have to finish this."
Ishizu's answer was a roar as another tail emerged.
Naruto lost his mind to the fox but still could make a massive wind infused Rasengan.
His last attack it would seem.
Ishizu's eyes widened at the size of the Rasengan.
What made Ishizu worry was the not that it was the normal reddish Rasengan Naruto made during his fight with Sasuke.
No, this mad Uzumaki got so much chakra from the fox that he made a Wind Style: Rasenshuriken with Kurama's chakra.
'Holy Sage. That's a big Rasengan and also not an ordinary.
If I clash with him, the bubble would defiantly be destroyed and everything would be for naught.
Fortunately, I am a Shinobi, so I think I have to cheat a bit.'
Under the mask, Ishizu was smiling proudly, seeing his students finally completing the next step of the Rasengan.
Unfortunately, he was the person who the attack was going to hit so he had to respond.
'I am proud of you Naruto. You made me use the last Rinnegan ability against you so don't be disappointed that it won't hit me or it would damage your hand.'
Ishizu's Rinnegan shined brightly as he charged at Naruto.
"ROOOOOOAAR!"
Naruto roared as he jumped at his enemy, wanting to slam the Rasenshuriken and defeat his opponent.
"Gakidō."
As the Jutsu hit the Preta path, it was absorbed together with the Kyuubi chakra.
"???"
Naruto had no time to react as Ishizu used this moment to hit his student in the back of the neck and the Jinchuriki lost consciousness.
The fight between the student and the teacher was over and the teacher won.
Ishizu POV
I stood next to Naruto's unconscious body as I felt that Zetsu was gone, believing Sasuke won. I fell on my b.u.t.t to take a breath.
It would take some time for Kakashi to arrive so I could take some time to recover.
Luckily for me, I had covered my body with a strong odor so that Pakkun wouldn't identify me after that.
'You amazed me Naruto. I didn't expect you to go into 3 tails mode trying to defeat me and going so far to help your comrade. I cannot wait to mold you into the Shinobi you always meant to be.
Jiraiya will comprise taking you with him on his trip but no way will you watch him look at women while doing nothing. No, let me handle Jiraiya. You have to grow stronger. It is my duty as a teacher to strengthen you.
I will make you train so hard that the next time you face Orochimaru or any other Akatsuki, you will destroy them.'
I felt Kakashi's chakra entering my sensor range, so I stood up, glancing one last time at Naruto before quickly disappearing and heading home to Konoha.
