Naruto: Journey Of The Strongest Teacher

General POV

During the night Fu slept on Ishizu's bed while the latter extracted the last bit of chakra from Chomei. At last, the girl could live a life without any problems and he had his first container full.

'1 full and 8 to go.'

He missed his bed, but he knew that there was no time to relax. Akatsuki was going to make a move and Ishizu needed to be one step ahead, so he made a wood clone to move to Sunagakure to monitor Gaara from afar before falling asleep on the couch.

Ishizu still needed some chakra to fill the first container, and what better time was there when the Akatsuki will try to extract Shukaku. The wood clone had enough chakra to survive until they extracted Shukaku, so Ishizu was not worried about anything to happen.

The only downside to his plan was that he had to reveal himself during the extraction to both Akatsuki and Konoha and would be seen as a wildcard.

Ishizu fell asleep with a smile because he could not believe his luck to meet Kenji and his wife in Uzu and having been gifted so much chakra.

Next day

Ishizu woke up by a knocking on his door. An ANBU told him to come to the Hokage office. The Godaime Hokage wanted to speak to him.

Hokage office.

"You wanted to speak with me, Tsunade-sama?" yawned Ishizu, coming through the door. It was early in the morning and Ishizu wasn't quite awake.

Tsunade nodded as she saw him.

"Since Naruto and you left so fast yesterday, I had no time to test you. I want to see how strong you and Naruto have become. That's why, right now, we are going to a training ground to see for ourselves what those years did."

Ishizu yawned while waving his head before nodded and they both went to the meeting place.

Training ground:

Ishizu watched from the side as his old team 11 arrived. He saw a few months ago how Ino and Hinata developed, but seeing them in front of him was a different view.

"Ah, this brings back memories, seeing all of you together," said Ishizu with a smile which Hinata and Ino returned, seeing their sensei back in the village. Naruto had a grin on his face.

"All right, listen up. This friendly spare will be between the 3 of you against your Sensei."

Ishizu g.r.o.a.n.e.d in annoyance. He was still tired, and fighting his students in a mock battle wasn't something he wanted to do right now.

"You have to be kidding me, Hokage-sama. I will have to be extremely careful about fighting Naruto with his new strength, but I am sure I will have to go all out to fight 3 of them at once," lied Ishizu to get away from responsibility.

"Stop complaining. You are an S-Rank Shinobi. Have you no shame thinking that fighting some Chunin would be hard?"

"Can't I at least get somebody too?"

"Fine. You will get help. Kakashi get your lazy a.s.s over here!" Tsunade screamed.

"Yes, yes, I am coming. No need to scream." Kakashi strolled to Ishizu. He too seemed tired, and both Jonin looked at each other.

"So, are you ready for the fight?" asked Kakashi with a raised eyebrow.

Ishizu only sighed. Of course, he had to be partnered up with this guy.

"Not only do I have to fight them, but I also get you as my teammate."

Kakashi smiled with his eye. "I enjoy having you as a teammate."

Ishizu only grumbled.

"So attack and attack and attack until the enemy is gone, huh?" asked Ishizu to which Kakashi nodded.

"Ok, the fight between Jonin's Kakashi Hatake and Ishizu Sasaki vs. Naruto Uzumaki, Hinata Hyuga, and Ino Yamanaka. This is a mock battle so no dangerous Jutsu such as the Rasengan, Chidori, or any other crazy technique you learned. Start now!"

Hinata and Naruto rushed forwards while Ino got back. Ishizu looked at Kakashi who nodded and they made a smoke bomb to hide inside.

Out of it rushed Ishizu and engaged Naruto.

Naruto started off by using his standard Shadow Clone. When Ishizu destroyed one Clone he was blown away by an explosion.

"Ah, the good old Bushin Daibakuha. Worked on so many Iwa shinobi's that even the old fossil had to give a speech to their shinobi not engage me blindly," replied Ishizu with a smirk.

"If I remember you and your clones were screaming in fear of dying that it was such a good bait for the enemy not to kill your clone," remakes Kakashi with a smile.

"Hey! Not talking about those things. It's embarrassing."

Their talking was interrupted by 10 Shadow Clones that attacked Ishizu while Hinata engaged Kakashi in a Taijutsu fight, but Kakashi was avoiding Hinata from closing his Tenketsus.

Ishizu quickly disposed of the clones with shurikens, avoiding the explosive clones.

"Enough of those Shadow Clones. I want to fight the real ones. Kakashi let's do it, make them fight us seriously."

Kakashi jumped to Ishizu, and both made hand signs.

"Fire Style: Fireball Jutsu, Wind Style: Great Breakthrough."

Fire and Wind combined and a massive firestorm rushed at the 3. Hinata made her rotation to block the firestorm, but she was hurt.

Seeing the damage Hinata had taken, Naruto ordered Ino to help her.

"Ino heal Hinata. I will take them both on," Naruto slammed his fist against his other hand, gesturing to be ready to fight.

Ishizu raised an eyebrow while Kakashi eye-smiled. One Naruto vs. two Jonin.

"You think you can take us both down, Naruto? Ishizu and I have been on a team for a long time. We have trained under your father. While we don't interact with each other much since we have different missions, we were a team in the last war."

"Who said about defeating you? I just need to stall time and my clone has already enough chakra gathered."

Ishizu who was a good chakra sensor snapped his head towards a direction where he could feel a clone of Naruto vanish and he could feel the nature energy building up in Naruto.

"I hope you are ready as the new Toad Sage is coming."

"Sage Mode? I thought we weren't going to use crazy techniques?" Ishizu looked up to argue with Tsunade.

"Just do what you want as long as it isn't deadly," was her simple reply.

As Naruto went into Sage Mode, Kakashi, in response, opened his Sharingan.

Ishizu went into his Panda Style: Speed Mode and rushed at Naruto.

"I know you have been training with the Toads, but in no way have you mastered it already! Take this!" Ishizu went for an uppercut, but Naruto barely dodged it thanks to the speed the mode provided.

As a response, Naruto used his leg aimed for Ishizu's face, but the latter avoided the attack only to feel a force still hitting him and pushing him away.

'Frog Kata is annoying.'

"Be careful, Kakashi. Toad Sage Mode can hit you with invisible nature energy. Don't engage him in very close combat."

Since Naruto could use Sage Mode than in response Ishizu made a Rasengan and rushed with it at his student.

"Hey, that's my technique! Don't copy me, Sensei!"

Ishizu stopped for his attack when he heard Naruto's words.

"Copy you?! I was the one who perfected it first. It was you who copied me!"

Ishizu's outrage gave Naruto enough time for summoning 5 Shadow Clones, and smoke appeared.

"I will bring you down, Naruto!"

"Hehe, this fight is at its end. Face this forbidden technique I made especially for you."

"Harem no Jutsu: Sensei Style."

As the smoke cleared, Ishizu's eyes widened in shock at the sight in front of him.

"Oh, Ishizu-kun? Don't you want to be with me and have a nice time in bed?" the feminine voice said.

"My shoulders feel kind of stiff. Can you give me a massage?"

"There is a wet place in my body. Do you want to touch it?"

Ishizu could not hold back the blood rushing out of his nose like a fountain at the sight of 5 n.a.k.e.d Kaguya's trying to seduce him.

Flashback no Jutsu

"Hey sensei. If you can't tell me the name of the person you love, can you at least show me how she looks like?" asked Naruto with a smile.

Ishizu had no problem doing that. So he drew a detailed picture of Kaguya Otsutsuki as he knew her from the anime. Of course without the horns, Byakugan, and Rinne-Sharingan. Ishizu didn't know if Kurama knew of her, so he made her look perfectly human while still preserving her beauty.

Flashback end

Naruto used the harem jutsu based on the picture and created a perfect Henge of human Kaguya.

It was very effective. Ishizu was on the ground. Out cold.

Kakashi has a small nosebleed as well but could still move and used this moment to go behind Naruto and hit the Jinchūriki in the back, sending him flying into a tree.

"Are you all right, Ishizu?" asked Kakashi as he came closer to Ishizu collapsed due to blood loss. Kakashi helped his comrade up, and Ishizu mumbled something before shaking his head and wiping the blood from his nose.

"Yes, I am fine, but I think I have anemia and need a session with Inoichi."

Kakashi smiled and gave his teammate a thumbs up.

"I always knew you were a pervert. You would make Jiraiya proud."

Ishizu glared at him in response.

"Finally, you are together. This was a big mistake, sensei!" came a voice from the tree.

Ishizu raised his eyebrow at the bland claim. "And what was the mistake?"

Ishizu saw Naruto putting his hands on the ground.

"I have teammates and I am an Uzumaki who can do Fuinjutsu."

Ishizu turned around and saw Hinata and Ino pressing their hands on the ground.

Ishizu jumped up but hit a barrier.

Kakashi looked around with his Sharingan.

"They trapped us in a barrier, clever."

Ishizu who has was trained by two of the best Fuinjutsu experts could immediately see the weakness of the barrier but he was too tired and anemic to do anything so he just stood and observed.

Naruto smirked as he made a Tiger sign.

"It is over. You have only to look down to realize it."

Ishizu and Kakashi looked down to see paper bombs laying on the ground.

"While you were focusing on fighting us, Ino-chan prepared everything. Naruto-kun needed to lower your guard, Ishizu-sensei, for just a moment so this could happen. The barrier is strong enough so you would not escape the barrier unscratched," Hinata explained to the two jonin.

Both jonin looked at each other before yawning and raising their arms in surrender.

"I should have paid attention to Ino. I focused too much on Naruto," said Ishizu.

"Yes, they have really grown up," nodded Kakashi in confirmation.

"I think I need to go home. I need to change my pants," muttered Ishizu before leaving the training ground with an awkward walking style.

Ishizu looked down, seeing a bulge in his pants.

'A pervert? I ain't denying it. I just hope this taught me a lesson to not freeze when I see the real deal.'
