Chapter 171: The Rasengan is Born! A Divine Moment Before the Gates, One More Time!
The spring breeze stirred white clouds, drifting toward the horizon.
Warm sunlight shone down on the abandoned village, beside the towering haystacks.
"So cool!"
"So cool!"
Such praise echoed in Minato's ears.
This was the first time someone had praised his technique to his face!
And this person had fought alongside him with perfect coordination, and also possessed exceptional talent for naming techniques!
Minato's face flushed slightly, feeling somewhat embarrassed.
After all, his expanding Rasengan had nearly hit his former comrade in the face, and Minato still felt guilty, unsure how to refuse.
At this moment, Tsukasa, seeing Minato's prolonged silence, realized he'd been somewhat abrupt.
In the shinobi world, a ninja's techniques were their most precious treasure—especially a unique jutsu like this, modified from the Tailed Beast Ball with ultimate shape transformation capabilities.
No hand seals, no elemental nature—seemingly any shinobi could learn it. Its extreme versatility meant its value was immeasurable!
His request to Minato, coupled with his Uchiha identity, made it hard not to suspect he wanted to copy Minato's technique.
Tsukasa immediately scratched his head, adding sincerely:
"Consider it me learning from you—I definitely won't let you lose out on tuition fees!"
"After we get our mission bounty back in the village, I'll borrow some more from the clan. In exchange, I have a few jutsu I can teach you."
But even with Tsukasa's offer, Minato thought for a moment and decisively shook his head, saying solemnly:
"Tsukasa, this technique is really dangerous. Even with your speed, you might not be able to keep up with its expansion and explosion—it could hurt you."
"I'm sorry. I'll teach you after I perfect this technique. Tuition fees aren't necessary—after all, we've fought side by side!"
Minato's words were both righteous and kind.
Seeing this, Tsukasa felt a little helpless.
Then he sighed, having no choice but to raise his hand and activate his Sharingan in front of Minato—
A rapidly spinning sphere of chakra gradually rose from his palm!
"Let me think... The first step is rotation—spinning in the direction of the hair whorl, concentrating the chakra in the center, keeping your eyes fixed on this point as a marker. Then comes power—increasing the chakra, making it rotate erratically, faster and faster. Finally, the third stage is maintaining form, which is a bit difficult."
As chakra was injected into it, having experienced the 100% body control under the Cursed Seal state, Tsukasa—with his current ability to control both body and chakra—although it was somewhat difficult, followed the steps that Jiraiya would one day teach Naruto. Soon, the Rasengan in his palm gradually began to take shape.
The first two steps went smoothly until the last one. Due to the rushed approach, his chakra began to fluctuate unstably.
Tsukasa quickly covered it with his other hand, like Naruto would do, grasping the Rasengan with one hand while constantly controlling the chakra protruding from the sphere's outer shell with the other.
Finally, a brilliant blue chakra sphere was painstakingly formed in his palm.
Rasengan!
A line of text immediately appeared before his eyes.
[You have mastered: Rasengan (A-Rank, Beginner)]
Although it was somewhat absurd, with Tsukasa's current foundation—coupled with the incredibly detailed Rasengan tutorial from his knowledge, his Sharingan, the Cursed Seal of Heaven, and superb body control—
This combination allowed him to use the Rasengan, which Minato hadn't even fully created yet, right in front of Minato!
Holding the Rasengan, Tsukasa wiped the sweat from his brow, then looked up at Minato.
"Your technique—you were probably aiming for this, right?"
Minato's expression had shifted from initial indifference to growing surprise, a desire to warn him of danger, and finally, utter shock upon seeing the complete Rasengan. He exclaimed:
"Tsukasa, how did you do that?!"
"Phew." Tsukasa dispersed the Rasengan, looking at Minato and patiently explaining:
"Your technique is almost complete."
"The inability to maintain form properly, the potential for explosion—it all stems from lack of stability. Making the chakra circulate erratically while maintaining its shape is incredibly difficult. But I used an extra hand, like a cat using both paws to pat a water balloon, constantly changing the direction of the water flow inside, suppressing the chakra protruding from the sphere's shape, and finally managing to temporarily stabilize it."
Minato was suddenly struck by enlightenment.
"The hair whorl, the cat's paws!"
His face lit up with delight, a blush rising on his cheeks. Excitedly, he raised both hands and began forming the Rasengan, just like Tsukasa had demonstrated.
Soon, an identical Rasengan was formed.
"It's taking shape!!"
Minato exclaimed, looking at the Rasengan in his hands with pure joy.
"Tsukasa, thank you!"
"Your theory is correct! Then, I'll name it—"
He looked up at Tsukasa, raising one finger and pointing to the Rasengan in his other hand:
"Light Wheel Cat Claw Reverse Inspired Whirlwind Uchiha Double-Palm Rasengan!!!"
Silence.
Hearing that absurdly long name, and seeing Minato forming the Rasengan with both hands like Naruto would, Tsukasa was momentarily speechless with embarrassment.
Damn it, he thought. I just taught the Fourth Hokage's signature technique to him like teaching a son, and he actually succeeded!
After a moment's consideration, Tsukasa couldn't bear to let the Rasengan—a technique born from the desire to protect Kushina—lose its original meaning.
He decided to let Minato use this technique properly, eventually naming it what it was meant to be!
So Tsukasa decisively interrupted Minato, shaking his head to remind him:
"Ahem, let's discuss the name later. Also, this method is just a shortcut. To use it in actual combat, you still need to refine this technique according to your original concept."
"Otherwise, this hand seal-less jutsu will lose its original purpose."
Minato thought for a moment and nodded in strong agreement.
"Hmm, you're right!"
The reason the Rasengan was so revolutionary was that it was a hand seal-less, instantaneous jutsu—a technique created to counter Tailed Beasts. If it still required both hands working together like hand seals, it would only waste time and miss opportunities.
Naruto had done that because he was limited by his talent and had no choice, compensating with Multiple Shadow Clone Jutsu—while normal shinobi couldn't produce that many clones.
"Phew~"
Tsukasa finally let out a breath, raised his serious crimson Sharingan, looked at Minato, and said solemnly:
"Minato, that move you used earlier was really important to me—very inspiring!"
"Just like how I'm using this clever method to inspire you now."
"I have no intention of stealing this jutsu that belongs to you. The conditions I mentioned earlier still stand. Moreover, we've fought side by side, and you've witnessed my abilities."
"A mere explosion won't kill me. You don't need to worry about my safety."
"So please—teach me that incredibly powerful move you just used!"
"This is really important to me!"
Tsukasa saw it very clearly.
Right now, although he possessed the Earth Grudge Fear Secret Technique, immortality, Fire Release: Chakra Mode, the forbidden technique Corpse Modification, the Cursed Seal of Heaven, and the Zero-Tails—a collection of absurdly powerful abilities—
He sounded practically invincible among Kage-level opponents, but he knew his own limitations. He'd struggled even against Ebizō, whose strength was relatively modest, though partly due to the chakra he'd expended breaking through Sunagakure's defenses.
This experience made him realize how fragmented his power actually was.
His Earth Grudge Fear Technique only possessed the ability to weave and stitch threads.
His immortality was merely slow regeneration and the concept of deathlessness—he lacked the jutsu resistance and curse abilities of someone like Hidan.
Fire Release: Chakra Mode worked well against opponents below Kage level, but against those above, it was more visual spectacle than practical weapon.
The forbidden technique Corpse Modification was incomplete, only allowing for localized rapid regeneration, and it carried significant risks. An enemy with advanced dōjutsu who could target and seal tenketsu points could easily deflate him like a balloon, much like Sasuke using Chidori to burst Shinnō.
The Cursed Seal of Heaven, whose abilities and risks he'd completely misunderstood, had no clear path forward. Orochimaru had even sealed it completely with the Evil Sealing Method, rendering it unusable.
The final piece—the Zero-Tails, known as the 'Shame of the Tailed Beasts'—was merely a juvenile form, like trying to run a high-end game on outdated hardware, constantly running out of chakra.
But now—
Inspired by Minato, this technique of unleashing Tailed Beast Ball-level power from a human body!
It could compensate for Tsukasa's weaknesses, maximizing his strengths while minimizing his flaws, merging everything into a cohesive whole!
How could Tsukasa not be tempted?!
Faced with Tsukasa's sincere gaze, Namikaze Minato fell silent for a moment.
A strange sense of satisfaction rose within him.
This reckless technique had actually earned such importance and acknowledgment from Tsukasa.
After a long pause, Minato nodded seriously, a bright smile spreading across his face.
"In that case—"
"Alright, let's do it again!"
