"Could he have completed the technique that our teacher couldn't?" Kakashi Hatake muttered in shock.
"How old is he? To independently develop an S-rank secret technique... how is that even possible?"
Kakashi's Sharingan widened as he clearly saw what was happening.
A powerful Water Nature Transformation was being infused into the Ragengan. The pressure it emitted was like a raging tsunami.
"What are you talking about?" Naruto Uzumaki asked, completely confused.
"That is the fully completed Ragengan," Kakashi said seriously. "A Ragengan infused with Nature Transformation."
"Just like this."
The Ragengan in Sora's hand began to visibly change.
The blue, constantly rotating sphere of Chakra began compressing toward its center.
Its size shrank drastically, yet the terrifying Chakra emanating from it made everyone feel a chill run down their spine.
"I call this technique Water Dragon's Rage Howl. You are the first person to witness it."
Before Sora finished speaking, the compressed aqua-blue Chakra sphere elongated.
More precisely, it extended outward.
The front formed a dragon-shaped spearhead made of flowing water, while the rear formed the spear shaft through rapidly rotating currents.
It looked exactly like a Dragon Spear.
If someone observed closely, they would notice that the entire Water Dragon Spear was rotating at an irregular and terrifying speed.
Yet while held in Sora's hand, it caused him no harm at all.
This perfectly demonstrated his incredible Chakra control.
The moment the Water Dragon Spear fully formed, an immense pressure spread across the arena.
"Incredible..." Kakashi Hatake inhaled sharply. "To apply Water Nature Transformation to this degree... is he really only twelve?"
Although Kakashi had created Chidori at a young age, it was only a high-level technique at the time. It took him years to develop it further into Raikiri.
"Naruto, hurry and forfeit!" Kakashi shouted suddenly.
His Sharingan sensed an extremely dangerous aura from the Water Dragon Spear.
If Naruto was hit directly, he would die.
"I can't!" Naruto shouted back. "Kakashi-sensei, I won't give up!"
Naruto possessed incredible resilience.
The more pressure he faced, the stronger his determination became unless he was completely crushed.
"Multiple Shadow Clone Technique!"
Hundreds of Shadow Clones appeared across the arena.
The number quickly approached nearly a thousand.
Unfortunately, numbers alone could not change Naruto's fate.
"Water Dragon's Rage Howl!"
Sora threw the Water Dragon Spear forward like a javelin.
Everyone in the arena witnessed a breathtaking scene.
"Ragengan!" Naruto roared as countless Shadow Clones rushed forward together.
The moment the Water Dragon Spear collided with them, it instantly transformed.
A massive rotating waterspout erupted into existence.
The vortex sucked every Shadow Clone into its terrifying spiral.
Naruto's own Ragengan looked incredibly small and fragile in comparison.
The rotational force and sheer volume of water were comparable to a deep ocean vortex.
Anyone caught inside it would feel as though they had fallen into the depths of the sea, crushed by immense pressure while being torn apart by the endless spinning current.
Once trapped inside, escape was nearly impossible.
"AHHH!" Naruto's painful scream echoed from within the vortex.
"Stop! Naruto forfeits!" Kakashi Hatake shouted.
Although Kakashi had not been allowed to teach Naruto many techniques due to Konaha's political situation, Naruto was still the only remaining bloodline of his teacher.
He absolutely did not want to watch him die.
But by the time he moved, it was already too late.
Even Kakashi felt powerless in the face of such a technique.
The entire audience stared at the arena in stunned silence.
Everyone felt as if they had been dragged into the depths of the ocean themselves.
The rotating waterspout made them feel insignificant.
Whether it was Sasuke Uchiha, who had recently learned a powerful technique and was full of confidence.
Neji Hyuga, the proud genius of the Hyuga Clan, or even Gaara, the One-Tails Jinchuriki, all felt a deep sense of helplessness and fear.
"Summoning Technique!"
Just as everyone believed Naruto would certainly lose or even die, a loud shout burst from within the vortex.
With a loud pop and a cloud of smoke, an enormous creature appeared in the arena.
"Huh? What's going on?" the creature growled. "Such terrifying Chakra! Damn it, break open!"
Naruto had summoned a gigantic toad.
The massive creature held a short sword and calmly smoked a pipe.
It was Gamabunta.
"What?! That's Lord Jiraiya's Gamabunta!" countless spectators gasped in shock.
The appearance of such a legendary Summoned Beast caused a huge uproar.
"Lord Jiraiya?" Sasuke Uchiha asked in confusion. "Kakashi-sensei, who is Jiraiya?"
"Jiraiya is one of Konaha's legendary Sannin," Kakashi explained. "Alongside Orochimaru and Tsunade.
It seems Naruto has become his disciple. That is likely how he learned the Summoning Technique and the Ragengan."
Kakashi sighed inwardly.
Within Konaha, aside from Jiraiya, almost no one dared teach Naruto powerful techniques.
"Why?" Sasuke thought bitterly.
Naruto now had a powerful mentor like Jiraiya guiding him.
Yet he, the genius of the Uchiha Clan, had no teacher like that.
Watching Naruto stand proudly atop Gamabunta's head while the crowd cheered, jealousy flickered in Sasuke's eyes.
Was that really the same Naruto he had always mocked as the dead last?
If Naruto was the dead last...
Then what did that make him?
At that moment, Sasuke remembered Orochimaru's earlier words.
Stimulated by both Sora's overwhelming power and Naruto's sudden growth, a dangerous thought began forming in his mind.
Once it appeared, he could no longer suppress it.
"Toad Short Sword Slash!"
Gamabunta did not have time to argue with Naruto.
Channeling his enormous Chakra, he unleashed a powerful slash using the explosive strength of his massive body.
The tremendous strike split apart the waterspout and broke free from the vortex.
Fortunately, Gamabunta was a water-type Summoned Beast skilled in Water Release.
Any other Summoned Beast would have been in serious danger.
With his knowledge of Water Release, Gamabunta barely managed to escape.
However, this was mainly because Sora's current strength was only at the Elite Chunin level.
If Sora were already a Jonin, even a powerful Summoned Beast like Gamabunta might have been severely injured or killed by that single technique.
