"So, Minato, your idea is to just condense chakra in your hand?"
"That's it?"
Kazuyama stared wide-eyed at Minato Namikaze, who had come straight to him after returning from the battlefield, insisting they work together on a new technique—forcing Kazuyama to cut his trip with Pakura short.
"Yes! The Tailed Beast Ball also forms by condensing chakra, then merging it in a specific ratio."
"If a Tailed Beast can do it, then we can too."
Seeing Minato's enthusiasm, and Kushina standing nearby in full support, Kazuyama cracked a sly grin. His tone suddenly turned teasing.
"So, are you trying to invent a new jutsu... or is there another motive?"
"Why else would you bring Kushina along for this?"
Minato's face flushed slightly. He did, in fact, have an ulterior motive. Kushina was a Jinchūriki—of the Nine-Tails, no less, the most volatile of them all. Lately, she hadn't been sleeping well due to the Nine-Tails stirring within her, and its chakra had started to leak out.
If not for their advanced mastery of Fūinjutsu, and the dramatic leap in Kushina's chakra quality as a member of the Uzumaki Clan, the seal on the Nine-Tails would've long since weakened.
"Kazuyama, you know who Kushina is. The Nine-Tails' chakra has started to spill out."
"It's more serious than we thought."
"I talked to Sensei about it, and his advice was to use specific training methods to burn off the excess chakra."
"That's why I'm so eager to create a new technique."
"Kazuyama, I need your help."
Kazuyama nodded. Minato saw him as a friend—and he felt the same. Why else would he have helped Minato win over Kushina? Okay, maybe his methods had been a little... blunt. But hey, it worked.
"Got it. But Minato..."
"Have you ever closely analyzed the Tailed Beast Ball?"
Kazuyama wanted to gauge just how much Minato really understood about the technique—he needed a starting point.
Minato rubbed his chin in thought.
"First, there's the flow of chakra... then, I think it involves spinning it... and finally, it condenses into a sphere?"
"No, wait—not just spinning. If it was only rotation, it wouldn't cause that kind of destruction."
Kazuyama nodded along as Minato muttered to himself. That "I've got it all figured out" look was just too much—Kushina couldn't resist jumping in.
"Hey, Kazuyama, what are you nodding for?"
"Don't tell me you've got an idea too?"
"I think Minato's spot on."
As Minato's number one fan, Kushina had to show her support.
Watching her stand by Minato like a fierce mama hawk, Kazuyama nearly burst out laughing.
"No, really—I think Minato's on the right track. It lines up with what I know about the Tailed Beast Ball."
"And I do have a few ideas of my own."
"First, gather the chakra in your palm."
Following Minato's earlier description, Kazuyama extended his hand and began concentrating chakra into it. The bright blue glow was instantly visible.
Next step—rotate the chakra. But not just any rotation—it had to be irregular.
Blue arcs of chakra started weaving and crossing, slowly spiraling and intertwining around one another.
Minato's eyes lit up as he watched the chakra in Kazuyama's hand begin to take on a spherical form. His excitement was unmistakable—even his voice was trembling with energy.
"Kazuyama, yes! That's it—you're a genius!"
"Keep going! Rotate it—irregular rotation!"
"Hahahaha! So that's how it works! That's how it works!"
"Kushina! Didn't I say Kazuyama would surprise us?"
Kushina's eyes widened in disbelief as she stared at Kazuyama. Not even if she used every cell in her body could she have imagined he'd actually pull it off based on Minato's theory.
And Kazuyama got exactly what he wanted.
[Ding! Host has demonstrated a prototype Rasengan in front of Minato Namikaze, successfully claiming the title of its creator and seizing a technique originally invented by Minato Namikaze! This plot is excellent!]
[Bonus: Ninjutsu Amplification +10%]
Now this was satisfying—using a system-rewarded jutsu to show off in front of its original inventor. What could be more perfect?
Meanwhile, Kushina, watching the spinning chakra sphere, reached out with her right hand to try it herself. But the next second—
Boom!
The chakra went wild and detonated in her palm.
The blast caught both Minato and Kazuyama's attention.
Poor Kushina had been blown off her feet and was now sitting on the ground, clutching her hand with a pained expression.
"Kushina, are you alright?"
Minato quickly knelt beside her, gently tending to her injured hand. From his pouch, he even pulled out gauze—earning a chuckle from Kazuyama.
"Well, look at you, Minato. Came prepared with gauze and everything, huh?"
Minato wasn't fazed by the teasing. He wanted to be a dependable man—carrying gauze was just part of the job.
Once Kushina's hand was wrapped, Minato turned back to Kazuyama.
That chakra sphere was still spinning, and Minato couldn't help but let out a breath of admiration.
"Kazuyama, you really are a genius. I just threw out a concept, and you actually brought it to life."
"Is this your interpretation of the Tailed Beast Ball?"
Kazuyama glanced at the glowing blue sphere in his palm and nodded without hesitation.
"Yeah. The Tailed Beast Ball is the most powerful offensive move a beast can make—that's what sparked the idea."
"But this is still just a prototype. Watch."
He pressed the sphere against the ground.
Boom!
A sharp explosion rang out. The ground beneath it rippled with circular marks—but the damage was shallow, clearly lacking in real power.
Minato frowned slightly. This was far from the destructive force he'd envisioned. If this was the limit, then even basic ninjutsu could do as much. It just didn't meet the potential he had in mind.
No... something was missing.
"Minato, I don't think the challenge lies in spinning the chakra—it's in compressing it."
"You've got to pack it down to the point where it can crush the enemy outright."
"Of course, I haven't gotten there yet. This is still just the beginning."
Gotta pace it out—no need to harvest all the crops at once. Better to cut them wave by wave.
