Higashino Shinichi's Light Blade Assault · Super Dance Roar Spiral Maru!

"It was about two years ago during a practical combat assessment. I saw Asuma-senpai in a fight with an opponent, able to highly concentrate chakra and stably attach it to his pair of blades, forming a blue glowing Chakra Blade. The power was astonishing."

Shinichi recalled.

"At that time, I thought, since chakra can be so highly concentrated on a weapon, then is it possible... without relying on external objects, to directly compress it highly and concentrate it in the palm, forming a brand new, bare-handed ninjutsu?"

Asuma?

Highly concentrated?

The Third Hokage suddenly understood, remembering the pair of chakra blades he had given his son as a birthday gift—Shinichi Monji.

Immediately, a trace of fear and reproach rose in his heart: This child was too bold!

Asuma used specially made Chakra Metal tools as a medium and guide, yet he dared to directly use his flesh and blood to try and simulate that kind of high-density chakra shape transformation. One slip in control...

Though thoughts churned within, the Third's face remained calm and composed. He did not interrupt Shinichi but continued listening attentively.

"After having this idea, I started trying. At the very beginning, it was simple—just trying to gather chakra toward my palm, but it was scattered and formless, completely lacking power. Later, I thought chakra needed restraint and shape... I tried using a water balloon, letting the chakra move violently and chaotically inside the sealed water balloon until it burst from within."

The Third nodded slightly. This first step was clear and correct in its thinking, touching on the basics of chakra shape transformation.

"After the water balloon succeeded, I felt the stability wasn't enough. So I switched to a tougher rubber ball, aiming to maintain a certain amount of chakra output and make it exist physically in my palm, continuously impacting the inside of the rubber ball until it burst. This stage took a long time and required very fine control," Shinichi continued.

"After the rubber ball also succeeded," he paused, as if recalling the difficulty at the time, "I felt something was still missing. It was like there was always a layer separating me from the stable concentration I imagined. Later... I thought of using a harder iron ball."

An iron ball?

So that's it. The Third Hokage finally understood why this child he had been watching closely had suddenly developed the habit of rolling an iron ball over a year ago.

He had originally thought it was just a hard training method to improve finger and wrist dexterity, aiding hand seals. It turned out there was a deeper purpose.

This child's talent far exceeds my expectations.

Suppressing the shock within him, the Third's tone remained calm and affirming as he said:

"I see. Drawing inspiration from observation, daring to put it into practice, and even coming up with such a step-by-step training method—these are very valuable qualities and talents."

He shifted the topic, "However, Shinichi, from what I observed, the first Rasengan you demonstrated, the one the size of a fist, has actually achieved a very stable and exquisite balance in chakra shape transformation and control. You could say this ninjutsu of yours is already quite mature and successful."

"Mature? Successful?" Shinichi's face showed obvious shock and confusion, as if he had never expected to receive this evaluation.

Seeing his reaction, the Third Hokage immediately understood the crux of the problem and couldn't help but shake his head with a wry smile: "It seems, Shinichi, you yourself have developed some kind of misunderstanding. In your view, the larger Rasengan that came later and the smaller one before it are two forms of the same technique, or rather, the former is an incomplete version, and the latter is a completed version you strengthened to make up for its shortcomings, correct?"

"Two techniques? But Third Hokage-sama..." Shinichi frowned deeply, his face full of confusion. He explained urgently:

"That smaller Rasengan, though its power was decent, its condensation speed wasn't fast enough, and its attack range was limited. In my own view, its flaws were obvious. It couldn't be considered a successful ninjutsu usable in actual combat. So I thought, maybe by injecting more chakra, forcibly expanding its volume and range of effect, I could cover up these flaws. But it's too unstable."

The Third Hokage listened quietly as he finished. His smile was gentle and wise as he slowly shook his head.

"Shinichi, this isn't a problem with the technique itself." His voice was calm but carried a convincing power: "The problem is that you are still too young."

Shinichi was slightly taken aback.

"Your total chakra reserves, relative to the demands of this technique, are still insufficient. Your fine control over chakra is still developing," the Third explained patiently, elucidating the principles of this ninjutsu:

"When you are a little older, as your body and spirit grow further, your chakra reserves will naturally increase, and your control will improve with training and experience. By then, you will naturally be able to condense it faster in battle, even approaching instantaneous activation. And that larger Rasengan, as your chakra increases and your control improves, will eventually become stable and controllable."

He paused, his gaze showing a vision for the future, and his tone carried a hint of encouragement:

"Not only that, with this Rasengan as a foundation, when your understanding of chakra nature transformation is deep enough in the future, you can try to infuse nature transformations like wind or fire into it. At that point, the Rasengan will truly transform into an S-rank secret technique of the highest level! I have high hopes for you on this path."

The confusion in Shinichi's eyes gradually gave way to realization and shock, then turned into a burning enthusiasm inspired by the encouragement. He took a deep breath and nodded solemnly: "I understand! Thank you for your guidance, Third Hokage-sama. I will continue to work hard and move in that direction!"

The Third nodded with satisfaction. But then his expression turned slightly more serious, and he spoke earnestly with a note of caution: "Shinichi, you are a rare genius, full of creativity and the courage to put it into practice. That is good. But independently developing high-level ninjutsu, especially techniques involving high-density chakra shape transformation, carries extremely high risks."

"In the future, if you have new ideas or encounter difficulties in training, don't always bury your head in solitary work. You can consult the teachers at the academy more often, or the seniors in the village. If you really run into something you can't solve..."

The Third Hokage looked into his eyes and said gently and clearly: "...you can also come and ask me."

That evening, in the Hokage's office.

"You will regret this!"

Bang!

No one knew what matter Shimura Danzō had come to see the Hokage about. All they knew was that in response to one of his requests, the Third Hokage had, for once, shown genuine anger, mercilessly telling him to get out, leaving no room for negotiation.

A few days later, Minato Namikaze had just returned home from a mission when Jiraiya, who happened to be in Konoha, came to visit.

"Minato, I heard a kid had an idea that coincidentally matched your original concept. He..."

Jiraiya recounted the full story of Higashino Shinichi developing the Rasengan. Minato listened quietly, a light of surprise and admiration gradually appearing in his eyes.

After hearing it all, he sincerely exclaimed: "That kid is truly an amazing genius. But... the name 'Rasengan' is quite good, but it doesn't seem quite fitting enough."

Jiraiya raised an eyebrow, intrigued, and asked: "Oh? Then what do you think it should be called?"

Minato thought seriously for a moment, a light shining in his eyes, and said word by word: "Higashino Shinichi Light Blade Initiation Roar Spiral Sphere."

"Hmm... I think a 'Super' should be added in the middle—Higashino Shinichi Light Blade Initiation Dance Roar Spiral Sphere."

Jiraiya: "..."
