Clang—
Kakashi used the recoil from the collision to leap backward, creating some distance.
"In that case, let's fight with everything we've got!"
He suddenly pressed his palms together, and black markings slowly began to appear on his face.
"Oh! It's Sage Mode."
Aoki Yoru didn't press the attack; instead, he watched him with interest.
He wanted to see how far Kakashi could go.
Before long, Kakashi's Sage Mode was ready.
He wrapped Natural Energy around his Lightning Style Armor and looked at Aoki Yoru, saying, "I remember last time you used this move to block Uchiha Itachi's 'Yasaka Magatama'."
"I have to thank you for the demonstration. If I had to develop it myself, it would have been much harder."
Aoki Yoru's pupils constricted upon hearing this, but he didn't have time to react.
The Lightning Style Armor on Kakashi's body rapidly surged and expanded, the pale purple lightning spreading along his silhouette.
In the blink of an eye, it transformed into a hundred-meter-tall lightning giant, with Natural Energy and Lightning Style Chakra interwoven on the armor's surface, glowing with a piercing golden light.
"Lightning Style: Raijin!"
"Oh! You've even learned this move. As expected of Kakashi-sensei."
This technique couldn't be replicated with the Sharingan alone; it required extremely precise Chakra control.
Furthermore, Kakashi was now incorporating Natural Energy, making it even more difficult.
Then, Aoki Yoru clenched his fist, mimicking Uchiha Madara. "In that case, I'll respond in the same way."
The entire Lightning Prison Cage trembled violently.
The lightning nets, ground patterns, and falling thunder around Aoki Yoru seemed to be pulled by an invisible force, frantically shrinking and converging toward him.
The pale purple lightning surged toward his body like a tide, rapidly expanding and extending along his silhouette. In an instant, it transformed into a hundred-meter-tall lightning giant, standing opposite Kakashi's giant.
"What is that?"
Not just Naruto and the others, even Tsunade and Jiraiya were stunned by this technique.
Although it didn't have the impact of Uchiha Madara's nearly thousand-meter-tall form, this size still meant overwhelming power.
Even they were shocked, let alone the others, who stood with their mouths agape, speechless.
They had been given too many shocks today; they never imagined Ninjutsu could be used this way.
At that moment, giant swords condensed from lightning appeared in the hands of both giants.
The purple-gold lightning swords crashed together in mid-air, and the blinding light instantly swallowed the entire field.
The shockwave from the collision swept out like a storm, tearing through the clouds overhead as if it were going to split the sky itself.
The immense wind pressure and the sound of electric currents snapped trees and uprooted them in the surrounding area.
Stray bolts of lightning from the battle struck the ground, blasting charred, smoking pits into the earth.
Everyone outside the field was forced back by the shockwave, and Naruto and his friends were blown off balance.
Even Tsunade and Jiraiya had to raise their hands to block the blinding lightning and the howling gale, their eyes filled with shock.
Meanwhile, the villagers of Konoha saw the battle between the giants in the distance, their faces filled with awe.
Fortunately, after the previous battle between Sakura and Yui's summoned beasts, Tsunade had the Anbu issue an announcement saying it was just combat training, so the public didn't panic.
Once they regained their senses, the villagers excitedly brought out sunflower seeds and beer; after all, such a spectacular battle wasn't even seen in movies.
The battle between the two had plowed through the entire training ground. Fortunately, it was on the outskirts of Konoha where few people usually went; otherwise, they wouldn't have dared to cut loose.
Kakashi was panting heavily; this technique took a massive toll on him, and even he couldn't sustain it for long.
Seeing Aoki Yoru still calm and composed, Kakashi decided to end the battle quickly.
This time, he had to see Aoki Yoru's trump card; otherwise, he would be a failure as a teacher, unable to even force his student to go all out.
Immediately, the two lightning giants began fighting again. Just as their weapons were about to collide, the three-tomoe in Kakashi's left eye instantly transformed into a four-pointed windmill shape with spiral patterns—the Mangekyo Sharingan.
"Kamui!"
The light from Kakashi's Mangekyo Sharingan surged, and the arm of Aoki Yoru's lightning giant was instantly swallowed by the power of spatial distortion. The entire arm, along with the lightning, was crushed and disappeared into the black-hole-like alternate dimension.
Seeing the move take effect, Kakashi made a prompt decision, and his Raijin swung its lightning blade toward Aoki Yoru.
Kakashi wasn't worried about Aoki Yoru's safety, as Aoki Yoru clearly still had strength in reserve.
Seeing the massive lightning blade, Aoki Yoru showed no sign of panic. Instead, he said with interest, "With such a huge amount of lightning and Natural Energy being sucked into the Kamui dimension, Obito is probably going to be cursing up a storm!"
Clang—
The lightning blade was caught by a giant golden hand. Then, with a surge of strength, the giant hand crushed the blade.
Looking closely, a hundred-meter-tall statue of the Thousand-Armed Guanyin slowly condensed from the void around Aoki Yoru. The phantom shifted from faint to dense, from ethereal to solid, as layers upon layers of hands slowly unfurled across the sky. With an aura that seemed to suppress heaven and earth, it stood silently above the ruins.
"Sage Art: Hundred-Type Guanyin!"
Kakashi's eyes narrowed as he thought to himself, "Is this the move he showed when he was training in the Forest of Death?"
Now, Kakashi didn't dare to underestimate this seemingly benevolent Guanyin at all.
Having entered Sage Mode, he could clearly sense that the Guanyin statue was condensed from Natural Energy.
"You've hidden it well!" Kakashi couldn't help but exclaim.
Meanwhile, the people who had retreated during the battle were watching intently, anticipating what would happen next.
Especially Jiraiya, who now had two toads standing on his shoulders.
After Kakashi entered Sage Mode, he had summoned the two toads, wanting to know just how far Kakashi's Sage Mode had progressed.
The female toad, Shima, said in disbelief, "That Guanyin is entirely composed of Natural Energy. How is that possible?"
"In the Ninja World today, besides the Great Toad Sage and the others, there's actually someone else who can use such a massive amount of Natural Energy."
Elder Fukasaku also took a deep breath. "Another remarkable person has appeared in the Ninja World!"
Jiraiya was also shocked; he hadn't expected Aoki Yoru to not only know Senjutsu but also possess such an enormous amount of Natural Energy.
Only by entering Sage Mode himself did he understand the terror of this technique.
He could probably find a way to counter Kakashi's Raijin.
But Aoki Yoru's One Hundred-Type Guanyin gave him a profound sense of lethality.
Gulp—
"Guy-sensei, who do you think will win?"
Might Guy shook his head solemnly. "No one knows until the battle is over."
Then, he unexpectedly burst into tears. "My most respected rival—Kakashi—has actually grown to this level without me realizing it."
"If it weren't for the fact that I can't open the Eighth Gate against a comrade, I'd really want to open the Gate of Death and have a proper battle with him."
