Gojo Yoru, You'll Regret This!

"What ninjutsu?"

Hearing that Gojo Yoru was going to teach her ninjutsu, Uzumaki Kushina immediately became interested.

Looking at the balloon in Gojo Yoru's hand, Uzumaki Kushina seemed to realize something. Her expression changed slightly as she said, "Wait... don't tell me you've developed other ninjutsu besides the Phantom Body Flicker Technique?"

After all, how could the training method for a technique that combined the Clone Technique and the Body Flicker Technique have anything to do with balloons?

"Heh... you caught on pretty quickly this time."

Gojo Yoru teased with a smile, then raised his right hand, palm facing upward.

With a whoosh, it was as though a sharp blade of wind had sliced through the air.

A blue-white vortex appeared out of thin air above Gojo Yoru's palm, spinning at high speed like a gear.

Gradually, the vortex grew larger and denser.

Upon closer inspection, it had transformed from one into countless tiny vortices, forming a white core.

Meanwhile, the blue energy on the outside gradually expanded from a thin membrane into an irregularly rotating energy sphere the size of a billiard ball.

From nothing to something, the two coexisted as the Rasengan took shape. The entire process was practically a display of skill.

Even Uzumaki Kushina could tell how difficult this ninjutsu was to master.

"Gulp..."

Uzumaki Kushina stared wide-eyed for a long while before swallowing hard. Looking at Gojo Yoru, she asked in a trembling voice, "Is this... ninjutsu without hand seals?"

"That's right. This is No Attribute ninjutsu without hand seals, called the Rasengan." Gojo Yoru smiled. "It doesn't require a Chakra nature or Nature Transformation. As long as your Chakra control reaches a certain level, you can learn it."

"You're really going to teach such a precious ninjutsu to me?" Uzumaki Kushina looked at Gojo Yoru in disbelief.

"Compared to me, the Rasengan is better suited for someone with as much Chakra as you," Gojo Yoru said sincerely.

Why had Uzumaki Naruto from the Original Work been able to rely on one move his entire life?

Because the Rasengan and the Multiple Shadow Clone Jutsu were the most suitable ninjutsu for a Nine-Tails Jinchuriki.

Other than not being the reincarnation of Asura's Chakra, Uzumaki Kushina was basically an upgraded Uzumaki Naruto.

With the complete Nine-Tails and the bloodline of the awakened Uzumaki Clan, her Chakra was only stronger than Uzumaki Naruto's.

Combined with her natural monstrous strength, the Multiple Shadow Clone Jutsu, Rasengan, and Monster Strength Fist were the ninjutsu most suited to her.

Just imagine it: Uzumaki Kushina creating hundreds or thousands of Shadow Clones, half of them holding Rasengan while the other half unleashed Monster Strength Fist and Painful Sky Leg. Just thinking about it made him pity her enemies.

"Yoru, you..."

How could Uzumaki Kushina have known about Gojo Yoru's training plan?

At that moment, his words struck her straight in the heart. Her eyes reddened, and a mist uncontrollably welled up in them.

Looking at Gojo Yoru, whom she had only known for a few months yet who was willing to teach her such an exceptionally rare ninjutsu without hand seals, Uzumaki Kushina asked in a choked voice the question every girl loved to ask: "Why are you so good to me?"

Yet faced with such a perfect atmosphere for boosting affection, Gojo Yoru utterly ruined it as he responded, "Can't be helped. You live in the First Hokage's house, after all. If I butter up this young lady now, I'll be able to strut around Konoha in the future."

"...Gojo Yoru, you bastard!"

The gratitude on Uzumaki Kushina's face instantly turned into gritted teeth, just as expected.

"Enough nonsense. Are you learning it or not?" Gojo Yoru asked irritably.

"I am! A rare ninjutsu handed to me for free would be a waste to refuse!" Uzumaki Kushina bared her teeth again. "I'll use the ninjutsu you teach me to give you a good beating!"

"Save the talk for when you're dreaming." Gojo Yoru looked disdainful, then tossed a bag of balloons to Uzumaki Kushina. "Take them to the bathroom and fill them with water. I'll teach you the first stage first."

"Gojo Yoru, you'll regret this!"

With a bang, the bathroom door was violently slammed shut.

A complaint got stuck in Gojo Yoru's throat, leaving him thoroughly uncomfortable.

Unable to think of any words to fire back, he suddenly felt that he still hadn't truly integrated into this world. His bloodline wasn't pure enough at all.

But a gentleman could take revenge even after ten years.

Gojo Yoru would remember this grudge and repay it a hundredfold ten years later!

Next, a training session that would definitely leave someone soaked began in Gojo Yoru's bathroom.

It was only because the Uzumaki Clan, like the Hyuga Clan, possessed an innate talent for powerful Chakra control, coupled with their vast Chakra reserves, that Gojo Yoru dared to teach the Rasengan to Uzumaki Kushina now.

The old Gojo Yoru, who calculated every step and spent every day worried that others might harm him, would only have secretly taught her the Rasengan after Uzumaki Kushina became the Nine-Tails Jinchuriki.

But now, Gojo Yoru had taught the Rasengan to Uzumaki Kushina early simply because he hoped she could quickly become stronger, so that after becoming the Nine-Tails Jinchuriki, she would not be so afraid of Kurama.

Moreover, the Rasengan was a product of Chakra control. Once Uzumaki Kushina learned this ninjutsu, learning the Monster Strength Fist and Fuinjutsu would also become much easier.

Conversely, this technique was a key that activated the Uzumaki Clan's talent for Chakra control.

At dusk, at Hashirama's house.

"Kushina, what are you doing?"

Tsunade, who had just returned home from work, saw Uzumaki Kushina standing motionlessly while holding a water-filled balloon. Unable to contain her curiosity, she walked over.

"I'm trying to inject Chakra into it and make the water inside spin irregularly, so I can burst this water balloon without using force," Uzumaki Kushina said with a serious expression, her eyes never leaving the water balloon in her hand.

"What's the point of that?" Tsunade was even more confused.

If it was for training Chakra control, the Five Great Shinobi Villages already had systematic training methods.

Beginners climbed trees, intermediates walked on water, and advanced practitioners learned Medical Ninjutsu or Fuinjutsu.

Uzumaki Kushina should have possessed a unique advantage in this regard.

Could this be a new method she had invented?

"It's... a secret."

Uzumaki Kushina had just been about to explain when she suddenly remembered how rare ninjutsu without hand seals was and quickly shut her mouth.

Without Gojo Yoru's permission, she could not reveal the Rasengan.

"You little brat, you won't even tell me?" Tsunade immediately flew into a rage, swinging her arm as though she were about to teach Uzumaki Kushina a lesson.

"No, no..."

Yet no matter how she tried to frighten her, Uzumaki Kushina refused to reveal even the slightest detail.

Tsunade could only give up helplessly.

After returning indoors, Tsunade looked at Uzumaki Mito, who was sitting in front of the kotatsu, but still could not suppress her curiosity. "Grandmother, do you know what Kushina is doing?"

"Tsunade, you're already an adult."

Uzumaki Mito smiled kindly. "Don't pry into the secrets between juniors when you're their senior."

"Fine."

Tsunade pouted like a child.

Unfortunately, no one had the pleasure of seeing this last trace of childish innocence.
