Great Ball Rasengan!

"Without Hand Seals? This is a Sealless Jutsu!? My god, what he developed... is actually a Sealless Jutsu!?"

Below the stage, a sharp-eyed upperclassman noticed that Shinichi had not formed any Hand Seals. He cried out in shock, instantly igniting the astonishment of the entire crowd.

"The density and rotation speed of that Chakra... It's terrifying! Just looking at it, I can already feel how powerful it is!"

The crowd erupted at once. Astonishment, disbelief, and feverish curiosity intertwined into a buzzing tide of noise.

On the stage, the eyes of Third Hokage Hiruzen Sarutobi had already blazed with an unprecedentedly sharp light after the initial shock, fixed intently on the pale-blue Chakra sphere.

But that wasn't all!

Shinichi gritted his teeth and let out a low shout, suddenly raising his right hand, which held up the Rasengan—

Boom!

As if infused with even more violent energy, the palm-sized pale-blue sphere suddenly burst into an even more dazzling radiance, expanding at an astonishing speed!

The swirling Chakra current produced an even deeper, more violent roar. The air was churned furiously, giving off a shrill howl!

In the blink of an eye, the Chakra sphere expanded from the size of a fist to the terrifying size of a head!

The Chakra strands flowing rapidly within it became clearer and wilder, radiating a terrifying fluctuation that made the heart tremble!

Great Ball Rasengan!

I don't just want you to sense danger. I want every one of you to truly experience what extreme danger is!

The Rasengan's power was considerable, but its size was too small. Unless someone was struck by it, it was difficult for them to feel overwhelmingly shaken at a glance.

The Great Ball Rasengan was different. Its power and oppressive force were obvious the moment one saw it.

Whoosh, whoosh, whoosh!

With the giant Chakra sphere fully formed, the wind above the training ground grew violent. The chaotic air currents swept up dust from the ground and tugged at everyone's clothes, making them rustle loudly.

A tangible sense of oppression, accompanied by the unstable radiance and roar emanating from the enormous Chakra sphere, clearly enveloped the entire venue.

If the Rasengan just now had merely made people marvel at its lack of Hand Seals and exquisite construction, leaving them with the impression that it should be quite powerful,

then this head-sized Great Ball Rasengan, radiating an aura of destruction, caused the expressions of every teacher and student present to change dramatically in an instant, whether they were newly enrolled students or experienced instructors!

This was no longer a theoretical "not bad" or "it might be powerful," but an intuitive, overwhelming sense of lethal threat that made their scalps tingle!

The Chunin-level teachers at the Ninja Academy narrowed their eyes, their bodies instinctively entering a state of readiness.

Some students were even intimidated by the terrifying Chakra fluctuation and could not help retreating several steps, the color draining from their faces.

"W-what rank of Ninjutsu is this?!"

"That Chakra is terrifying... How could he possibly control it?!"

"Y-you've got to be kidding... Is this really a technique a student could develop?!"

Exclamations rose one after another, but even more people held their breath, staring fixedly at the Chakra sphere on the stage that resembled a miniature storm—and at the black-haired boy in the eye of the storm, struggling somewhat to maintain it.

The Third Hokage's body had gone completely rigid. The two advisors beside him stood up abruptly, their faces filled with incredulous shock.

By now, the Third Hokage had noticed the instability of the energy sphere and the boy's gradually paling face. Without any hesitation, he stepped forward and firmly pressed one hand against Shinichi's trembling shoulder, while his other hand reached toward the dangerous Great Ball Rasengan.

A gentle yet immense Chakra intervened, guiding and dispersing it with incomparable precision. The heart-stopping Chakra sphere rapidly shrank and dimmed, ultimately transforming into a breeze that scattered into the air.

"Koharu, Homura, continue presiding over the ceremony." The Third Hokage gave the quiet order without turning back. Then he turned toward Shinichi, whose face was pale as he panted, the sternness on his face transforming into profound gentleness. "Child, come with me."

He gave no one time to react before taking Shinichi and rapidly leaving the noisy ceremony grounds beneath the countless shocked, bewildered, and awed gazes of the teachers and students.

"That child was far too reckless! He actually dared to independently develop and attempt such a dangerous Ninjutsu!" Utatane Koharu said, watching their departing figures with lingering fear.

"He was indeed somewhat impulsive and reckless." Mitokado Homura adjusted his glasses, but his gaze behind the lenses had grown much sharper. "However, Koharu... it seems our Konoha has produced an extraordinary Genius!"

After Shinichi was personally taken away by the Third Hokage, the two advisors continued presiding over the opening ceremony.

But the storm of thought Shinichi had stirred up could never be quelled again.

"An A-Rank Ninjutsu! That was absolutely the fluctuation of an A-Rank Ninjutsu!" (Note:)

"That even larger one afterward... might even have been an S-rank! It was extremely unstable, but that oppressive force..."

At the teachers' seats, the well-informed Chunin instructors exchanged their opinions.

Before long, the news that "third-year student Higashino Shinichi independently developed an A-Rank Sealless Jutsu, and perhaps even an unstable S-rank Jutsu" swept through every corner of Konoha like the most ferocious wildfire.

And Higashino Shinichi, the center of this storm, was currently standing inside the Hokage Office.

He lowered his head slightly, both hands hanging uneasily at his sides. His face carried the characteristic expression of a boy who had caused a major disaster, mixed with lingering fear, tension, and helplessness.

The Third Hokage Hiruzen Sarutobi, who had taken everything in, had already returned to his seat behind the broad desk.

His expression had become utterly peaceful, even carrying the benevolence unique to an elder. He slowly spoke, his gentle voice breaking the silence in the room:

"Shinichi, there's no need to be so nervous. Relax and sit down." He pointed at the chair opposite him. "I brought you here not to scold you. I merely have some questions about that technique and wanted to discuss them with you properly."

"Yes... yes, Third Hokage!" Shinichi hurriedly replied. Following his instructions, he sat upright in the chair opposite the desk, placing both hands properly on his knees. He looked exactly like a good student listening attentively to a lecture.

"Have you given this Ninjutsu a name?" The Third Hokage lifted his teacup and took a sip, his tone casual and conversational.

"Rasengan! Third Hokage, I named it Rasengan." Shinichi answered.

"Rasengan... a rotating Chakra sphere. A very fitting name." The Third Hokage nodded approvingly and set down his teacup, his gaze turning gently toward Shinichi. "Now then, Shinichi, can you tell me how you came up with and ultimately developed this Rasengan?"

"Yes, Third Hokage." Shinichi assumed a thoughtful expression for a moment before speaking. "Come to think of it, I have Asuma to thank for the inspiration."

"Oh?" The Third Hokage's eyes flickered.

And what about my son?

"It all began two years ago..."
