"Shin, this jutsu is amazing! I want to learn it."
Seeing the power of the Wind Style: Rasenshuriken, Kushina looked at Shin with eyes sparkling with excitement.
Shin shook his head. "Kushina, it's not that I don't want to teach you, but you aren't suited to learn this jutsu right now."
"Kushina, don't even think about S-rank jutsus for the time being; they aren't that easy to master," Tsunade added.
S-rank jutsus are powerful, but they are also incredibly difficult to learn. The Wind Style: Rasenshuriken is particularly challenging because it is an S-rank forbidden jutsu.
When training with the Wind Style: Rasenshuriken, it is very easy to injure yourself.
"The Wind Style: Rasenshuriken is a jutsu that compresses wind-natured chakra into microscopic needles to attack the body's cells directly. Any ninja hit by it will be left paralyzed, if not killed outright."
"However, the Wind Style: Rasenshuriken has its drawbacks. If your control is poor during training, you will hurt yourself. An incomplete Wind Style: Rasenshuriken cannot be thrown, so you will be caught in the blast when attacking enemies."
"It is best to use *Shadow Clone*s when training for this jutsu."
Shin explained the details of the Wind Style: Rasenshuriken to them.
Whenever Shin trained in this jutsu, he always used *Shadow Clone*s to complete it, only performing it himself once it was fully perfected.
But if Kushina were to try and use *Shadow Clone*s to train like Shin, she would run into trouble—she lacked the necessary chakra.
He estimated that after a few failures, her chakra would be completely depleted. Kushina simply wasn't ready for this training yet.
"The chakra consumption is massive. Even with your large reserves, Kushina, you can't afford the drain. It's better to wait until later to train for it."
"Alright then."
Kushina didn't seem too disappointed.
"However, Tsunade, you could train in this." Shin turned his gaze toward Tsunade.
Tsunade had enough chakra. As a member of the Senju clan, Tsunade possessed a Sage Body. Although it couldn't compare to Shin's Perfect Sage Body, her chakra reserves were still unimaginably vast.
Don't let the fact that she is currently an Elite Jonin fool you; in terms of raw chakra volume, Tsunade's reserves were several times that of Sarutobi Hiruzen.
A ninja with a Sage Body who grows to maturity basically never runs out of energy, and a ninja with a Perfect Sage Body has chakra so overflowing that they can never use it all.
Shin felt that his current chakra, while perhaps not equal to the Nine-Tails, was definitely not less than that of the Eight-Tails.
"You want to teach this jutsu to me?" Tsunade looked at Shin in surprise.
This wasn't some common technique; it was an S-rank jutsu. To offer it so generously—could this brat actually be interested in her?
"If you don't want to learn it, forget it. Honestly, it's just an S-rank jutsu; it doesn't mean much to me."
Shin shrugged.
This wasn't Shin being arrogant. The Wind Style: Rasenshuriken was indeed strong, but there were certainly jutsus even more powerful than it.
"Since you're willing to teach it, of course I don't mind learning. This is an S-rank jutsu, after all."
Faced with an S-rank jutsu, even Tsunade couldn't help but be tempted.
"In that case, you'll have to call me Teacher Shin." Shin looked at Tsunade with a smile.
"You're asking for a beating!" Tsunade raised her fist in annoyance and swung it at Shin.
Shin dodged her fist with a smile. In his eyes, Tsunade's movements were sluggish, and he could evade them with ease.
"Damn it!"
Tsunade realized with frustration that she couldn't seem to do anything to this brat.
"Hurry up and say it! Think about what a great opportunity this is—one 'teacher' for an S-rank jutsu!"
Kushina said to Tsunade with a hint of exaggeration.
"Mikoto, don't you think I'm right?" Kushina nudged Mikoto, who was standing beside her.
"Mm, I think you're getting a great deal, Teacher Tsunade," Mikoto said with a smile. She and Kushina were clearly just enjoying the show.
Tsunade let out a soft huff. To think she would call a brat like Shin 'teacher' for a mere S-rank jutsu—in her dreams!
"Teacher Shin."
Well, it seemed no one could escape the law of 'true fragrance,' not even Tsunade.
Shin was stunned. To be honest, he had only been joking with Tsunade; he truly hadn't expected her to actually call him teacher.
Given Tsunade's personality, it was hard for Shin to imagine.
"What? Are you looking for a beating?"
Tsunade's face flushed red under the gazes of Shin, Kushina, and Mikoto. After saying those words, she felt as though her dignity had completely crumbled.
"Since you've sacrificed so much, Tsunade, my disciple, I shall teach you the Wind Style: Rasenshuriken," Shin said with a smile.
Tsunade gritted her teeth, feeling that Shin was just asking for a beating. Why on earth had she been possessed to actually call him Master Shin?
If time could turn back, Tsunade would definitely go back to retract those words and let Shin have an intimate encounter with her fist.
Seeing Tsunade about to lose her temper, Shin coughed twice and began to explain the key points of the Wind Style: Rasenshuriken to her.
"So, I have to learn the Rasengan first?"
"Exactly. The Rasengan is the foundation of the Rasenshuriken. If you can't perform the Rasengan, how could you possibly release the Rasenshuriken?" Shin nodded and said.
Shin had already taught Tsunade the Rasengan, though she hadn't mastered it yet. Once the key points were understood, the Rasengan wasn't particularly difficult; he estimated Tsunade would be able to learn it in a few days.
"By the way, Tsunade, as a princess of the Senju Clan, you shouldn't be lacking in S-rank ninjutsu, right?"
"Who told you I'm not lacking in S-rank ninjutsu? I could get my hands on S-rank Wood Release, but all the other S-rank techniques were locked away in the Scroll of Sealing by my granduncle," Tsunade replied to Shin.
Tsunade couldn't use Wood Release anyway; aside from the First Hokage Senju Hashirama, no one else currently possessed that ability.
As for the other S-rank ninjutsu developed by Senju Tobirama, such as the Flying Thunder God and the Impure World Reincarnation, they were all stored within the Scroll of Sealing.
Even if they weren't in the Scroll of Sealing and Tsunade could see them, she might not necessarily be able to learn them.
The Flying Thunder God required a talent for space-time ninjutsu, and the Impure World Reincarnation was a forbidden technique that was notoriously difficult to cultivate.
"Right, Shin, don't expose this S-rank ninjutsu easily," Tsunade said seriously.
S-rank ninjutsu were extremely rare in every nation, the kind of techniques even Kage-level Ninja coveted.
If it were exposed, it would likely invite danger, especially from a guy like Danzo; Tsunade didn't believe for a second that Danzo wouldn't be greedy for an S-rank technique.
"Rest assured, I won't expose it easily. Besides, ordinary people wouldn't be able to force me to use the Wind Style: Rasenshuriken anyway."
Unless an unexpected situation arose, Shin generally wouldn't cross paths with exceptionally powerful ninja, and against ordinary Genin or Chunin, he would never need to use the Rasenshuriken.
He wouldn't even need it against a Jonin; nothing was faster than just cutting them down with a single strike.
Tsunade nodded, feeling quite at ease regarding Shin.
"If Nawaki had even half your strength, I wouldn't be so worried. I wonder how he's doing over there with Orochimaru."
At that moment, a certain youth currently hauling manure suddenly let out a sneeze.
"Could someone be thinking of me?" Nawaki scratched his head before continuing his work.
As for why he was hauling manure, it was naturally because Orochimaru had accepted a mission to clean up a ranch, which included clearing out the waste. One had to admit, Orochimaru had certainly picked a "great" mission.
