Naruto: Journey Of The Strongest Teacher

General POV

In *DD* Ishizu was sitting on the grassy ground while he was holding a string of hair in his hand and examining it.

"This is so boring. You looked at that hair for over an hour like it is a treasure. Is it so mesmerizing?" asked Yang Yang as she rolled around Ishizu.

"This is no ordinary hair of some random person. It belonged to a human coming from the special Kaguya clan, Kimimaro Kaguya."

Suddenly a voice came over Ishizu's shoulder.

*Oh, then is it connected with your future wife, Kaguya Otsutsuki?*

Ishizu jumped up, seeing Po behind him with a smile.

"Stop doing that and maybe. The boy had a Kekkei Genkai that could make bones to weapons, but you can't compare it to Kaguya's all-killing ash bone. Kimimaro Kaguya died, but if not by battle then he would have by genetic mutation. It must have been an autoimmune disease where the more he used his bones, the faster his own body rejected him.

Incompatible DNA.

My theory is that the Kaguya Clan inherited Kaguya's genes from Hagoromo. A lot of inbreeding to keep the Kekkei Genkai alive helped them maintain the genes but unfortunately, there were problems. Human and Alien DNA combined, backed with a lot of mutations over the centuries, made it so if somebody got the Kekkei Genkai they wouldn't survive it. That was the problem, but what if I could combine this DNA with another DNA from the Otsutsuki?" Ishizu scratched his head while thinking.

"Is there even a DNA that is similar to Kaguya's and it survived?" asked Yang Yang curiosity as she gazed at the hair strand trying to grab it from Ishizu who stopped her with his foot.

"As the descendants of Hamura Otsutsuki, the second son of Kaguya, the Hyuga's are the next relative. The question is if I give Kimimaro's DNA to Hinata, would she awaken Kimimaro's Kekkei Genkai or the Ash-bone? If nothing happens, then maybe going to the moon and getting some Otsutsuki DNA from them would do it."

'In the movie, Toneri awakened the Tenseigan by getting Hanabi's eyes. If I inject Otsutsuki DNA into Hamura's reincarnation, then maybe Hinata might awaken it.'

*So you will inject your student foreign DNA to strengthen her?* asked Po with a smile only for Ishizu to frown.

"Do you think I am a monster like Orochimaru? Even if I could do it, it is still too much trouble explaining the reason and I need to test it before being sure. No, I will ask her to undergo this procedure if I know it is safe and if she declines I won't pester her. It's her decision. Naruto has already a destiny ahead of him and there is already a plan being made for the next Slug Sage.

I told my students from the first day we met that I would make them each a powerhouse and I won't go back on my word. The thing is that giving Hinata the Tenseigan will only be done when I think nobody can defeat me. That will take some time because as you know I am very paranoid."

Later

Ishizu POV

I was walking around *DD* when I heard someone calling for me. A small panda ran to me and handed me a scroll from one of the messengers. Kirigakure was in turmoil, and a major battle would soon happen. This was a good time to get some chakra from Isobu. I wanted to see how Zabuza and Haku were doing, as well as establishing a beneficial relationship between Konoha and the future Mizukage, Mei Terumi.

"Tayuya, I will be going to Kiri. Do you want to come with me?" I asked the former Orochimaru minion.

The redhead stopped fighting a panda before looking at me.

"Kiri? Are you crazy? Those guys are in a war. Why should I risk my life going there?" asked Tayuya.

"That's a no, huh? Well, have fun."

Kirigakure

'Hmm, I should find the rebellion first. Those should be the guys that fight against the current Mizukage. Yagura is under the control of Obito, and helping Mei win the war would make it easier for the villages to help each other in the future.'

I activated my sensor ability and widened it out.

Rebellion camp

"What is wrong, Ao?" asked Mei when she saw her bodyguard stiffening before looking outside.

"Somebody powerful just scanned us. Going by his chakra, he is an S-rank."

His eyes widened in horror.

"He is heading towards the camp!"

Someone that powerful alarmed Mei, so she quickly headed out to confront the person personally.

"Zabuza, Ao, come with me. Try not to start a fight. We need our strength to fight Yagura."

Ishizu POV

I made myself comfortable on a stone and waited for their arrival. After a few minutes, I felt 3 chakra signatures closing up with one following closely behind them. Mei Terumi, a dark red-haired woman in her 30s or 40s, arrived as she looked at me curiously but ready to fight if I showed a threat to her group.

"Who are you and why are you hiding behind a mask? A Shinobi of your power should show his face to a woman like me."

Despite feeling my chakra, Mei held her composure. No wonder she would be the next Mizukage. I bowed to show my respect.

"Many reasons. First, it is for protection against your bodyguard. His Byakugan can't see through it which goes with the other, identity reasons. If a fight is going to happen, I have an advantage as I know a lot about you and your two bodyguards hiding. Maybe I will show you my face if you get your bodyguards out. The Yuki girl can also stop hiding. I am a very powerful sensor."

Mei turned around.

"You all come out. The same goes for you, Haku," she commanded and the three Shinobi came out.

"Haku, I told you to wait at the camp. You are no match against him," said Zabuza as he glared at his student.

"He was never a match. The last time we met, Haku gave me your location, Zabuza," I spoke in a musing tone.

Zabuza's eyes widened in realization.

"So it is you. I always wondered when you would come."

Mei turned to Zabuza: "Who is he?"

I interrupted the coming conversation.

"Ah, ah, ah, Miss Terumi. Before those two give away my identity, I want to tell you the reason I have come here. I don't want to fight you during a time such as this."

Mei glared at me.

"Speak."

"I was the one who let Zabuza and Haku live when I could have killed them, but you know that nothing is for free. I am here and ask them or your rebellion for help."

"And what kind of help do you want from us? We have more important things to do then help a stranger who is hiding his identity," asked Mei as she crossed her arms.

"Simple. I can help you stop this civil war," I told her my goal in a single sentence.

"Your voice carries confidence. You speak as if you could do it alone. If we could do that so easily, there wouldn't be any more fighting," spoke Ao in a disbelieving tone.

"That is true, but now I am here. I am sure that some of you already suspected that someone controls your Mizukage and that is correct. I also understand the reason for this.

It's simple: He hates you. I mean, Kirigakure. You took someone from him during the last Shinobi War, and now he seeks revenge. He weakened your power by manipulating Yagura and going on a Kekkei Genkai hunt. I am here to help you stop this war once and for all."

"And what do you get out of it? There is always a catch. What do you want from us if I agree?" asked Mei impatiently.

"I want to have a beneficial relationship between my village and yours," I explained to her.

I looked at Zabuza.

"You can tell her my identity. It is not something that they can abuse anyway."

Mei turned to Zabuza.

"Who is he?"

"He is a famous S-ranked Shinobi from Konohagakure, Ishizu Sasaki the Strategist," answered Zabuza as he took out a Bingo Book and showed her a picture.

"Ah, the picture is so hot. Do you want to be my husband?" came the direct question out of nowhere.

Everyone looked at her with familiar expressions. I smiled before shaking my head and taking off my mask.

"I am sorry. You really are a beauty and I wish you all the best, but I know my future wife won't let it slide if I get into another relationship and I guarantee that she is more powerful than I am. I value my life. Thank you very much."

Mei sighed in disappointment.

"A bummer. Now Sasaki-san, tell me why should I believe your claim to help my village?"

I shrugged.

"Because why not? Do you want to fight all the time against other villages? War is costly. Also, a peace treaty between our villages could be the beginning of a new era. One without constant fighting. My student will be one of the next Hokage and he will change the world. His name is Naruto Uzumaki."

"Oh, a relative? My grandmother was one, and I know how strong-headed she was. If I agree to your demands, what can you do to end this war?"

I smiled.

"I am confident I can fight against Yagura. All you have to do is draw him out and handle his henchmen. The only thing I can't guarantee is that he will survive our fight. If he dies by my hand, I will compensate by telling you the location of the Sanbi and Konoha won't interfere with getting it."

I could see that Mei wanted to disagree. Nobody would give away the location of a Bijuu to another village if they could get it by themselves, so I quickly spoke further.

"What if I could give you a person with a Kekkei Genkai that you thought have lost?"

Mei returned the smile, not believing the last claim.

"There were many powerful clans with strong Kekkei Genkai in Kiri that were hunted down by the enemy. Who do you have in mind?"

"I have somebody from the Kaguya Clan, with the Shikotsumyaku."

"There lived many people in the Kaguya Clan but all died and I never heard their found one with this particular Kekkei Genkai. Why should I believe you that not only is one of them alive but he has this Kekkei Genkai?" asked Mei with a frown on her face.

"This one is alive because when he was young Orochimaru took him before his clan died. I captured him so he is in my custody."

"Something tells me there is more to it, right?" asked Mei.

I nodded.

"Yes, there is a problem. See, Kimimaro, that is his name, has an illness. It prevented Orochimaru from taking his body. An autoimmune disease. His own bones are killing him, and not even the best medic from the snake could heal him. I found a way to cure his disease so if you agree to my request I will give him to you in perfect condition.

"So there is something in Kirigakure that only the rebellion has and that can cure this boy?" asked Mei with a raised eyebrow.

I pointed at Ao.

"I need some Byakugan cells. Not the whole eye, but cells to cultivate and inject into his body. The Kaguya and Hyuga are distant relatives. If you give me permission to do so, I will give you the boy with the Kekkei Genkai Shikotsumyaku. So what do you say? Do we have a deal?"
