In the Heavenly Screen...
Momoshiki looked down at the controlled crowd from his superior position, his left hand blazing with intense Kakkō: "Turn to ashes!"
"Now! Boruto!" Sasuke suddenly turned around and shouted.
Behind the rocks in the distance, Boruto rapidly gathered Chakra in his hands, and a deep blue Rasengan took shape in his palms.
"Rasengan?" Naruto's eyes widened. "When did he learn that?"
Boruto forcefully hurled the miniature Rasengan, no bigger than the palm of his hand. "Go!"
Momoshiki glanced at him dismissively, casually raising his right hand. "It's better to hide; why throw your life away?"
Everyone watched the tiny Rasengan with bated breath.
Swish!
Just as it was about to touch Momoshiki, the Rasengan vanished into thin air!
"What?" Chōjūrō exclaimed, "Did it miss?"
Momoshiki curled her lips in a mocking smile, "Can't even touch it, truly pathetic—"
Bang!
A heavy blow suddenly slammed into Momoshiki's face! The Vanishing Rasengan reappeared from the void, blasting him away! The Shadow Possession Jutsu shattered instantly!
"Dad!" Boruto rushed over.
Sasuke lowered his hand seals. "I promised him I'd take him on as my student if he learned the Rasengan." A hint of admiration flashed in his eyes, "I didn't expect him to have incorporated Lightning Release nature transformation into this 'Vanishing Rasengan'."
"The Vanishing Rasengan?!" Adult Naruto's mouth gaped open wide enough to fit an egg. "This kid invented it?!"
Boruto scratched his head sheepishly. "Mr. Sasuke, I..."
Sasuke smiled, a rare occurrence, while Naruto looked at his son with a face full of pride. "Good lad! You've really got it!"
"You damned bastard!" Momoshiki crawled out of the ruins, his face contorted in a ferocious grimace. "With such a petty trick—" He swallowed his treasured pill, and a burst of violent Chakra erupted instantly!
Amidst the howling wind, Darui gritted his teeth and said, "He's going to fight to the death!"
"Boruto," Naruto suddenly grabbed his son's shoulder, "One more Rasengan!"
"But my Chakra..."
"Trust me."
As Naruto's palm touched Boruto's, a dazzling golden light suddenly erupted! The Rasengan expanded rapidly, and within the Chakra, the smiles of Jiraiya and the figures of Minato and his wife, Neji's Byakugan, and Hinata's resolute face faintly appeared...
"It's so heavy..." Boruto's arms trembled. "This is Dad's..."
Sasuke's Kusanagi Sword slashed through the sky. "You only have one chance."
"I understand!"
Momoshiki roared as he unleashed Ninjutsu at them, but Sasuke blocked them all with exquisite swordsmanship. Then Sasuke threw his Kusanagi Sword at Momoshiki, which Momoshiki dodged in the blink of an eye—
"Amenotejikara!"
Sasuke instantly swapped positions with the Kusanagi Sword, flashing behind Momoshiki. Then he unleashed Chidori.
"That's all the trickery I can come up with!" Momoshiki suddenly turned his head, his right palm wide Rinnegan, ready to absorb the incoming Chidori.
However--
"Whoosh!"
Sasuke suddenly released Chidori, Kunai a cold glint flashed in his kunai!
"What?!"
"Pfft!"
The Kunai precisely pierced Momoshiki's palm, Rinnegan!
"Ahhh! You—!" Momoshiki roared in fury, raising his leg and delivering a powerful kick that Sasuke flying. Blood trickled from Sasuke's mouth as he flew backward, but he wore a triumphant smile: (The rest... I'll leave it to you, Boruto!)
"Drink up!"
Boruto charged forward like a golden lightning bolt, delivering a straight punch Momoshiki's face!
"A mere trick!" Momoshiki as he grabbed Boruto's wrist, "But unfortunately--"
Boruto was being restrained, suddenly grinned. "That's hard to say."
"Bang!"
A burst of white smoke revealed Shadow Clone!
"What?!"
Two Borutos simultaneously charged out from the left and right sides, their Rasengan aimed straight for Momoshiki's vitals!
"Boring!" With a flick of her Momoshiki easily defeated the clone.
But in that instant—
"I'm here!"
The real Boruto has already leaped into the sky, and the giant Rasengan in his hand, which is fused with Naruto's Nine-Tails Chakra, bursts out with dazzling golden light!
" Rasengan --!"
Momoshiki hastily raised his hand, a crimson Chakra ball condensing in his left. "This move was indeed very risky... but as I said, there won't be a second time!"
Two world-destroying energies collided with a deafening roar! The very space trembled violently! The shockwave ripped the clouds within a kilometer radius to shreds!
"That's all!" Momoshiki snarled, "I am Ōtsutsuki Otsutsuki--"
"It's not over yet!" Boruto roared, his azure right eye suddenly flashing with a mysterious light!
Boom!
The golden Rasengan swept through the enemy ranks, instantly shattering the red Chakra ball! Momoshiki stared wide-eyed in disbelief: (Impossible... I actually...)
A dazzling light engulfed everything. When the intense light faded, Boruto was seen kneeling on one knee, panting, while Momoshiki...
(The outcome is decided!)
The real Shinobi World...
Land of Snow
"Pervy Sage! Karin! Look!"
Naruto sprang up from the snow with a somersault, pointing excitedly at the Heavenly Screen, his golden hair swaying wildly in the sunlight.
"My future self is so cool! That giant Rasengan! It's bigger than a meteorite! It blasted that Momoshiki away!!" He gestured with his hands to mimic the Rasengan motion, spinning around in the snow several times, almost tripping over his own foot.
Suddenly, he paused, his voice unconsciously lowering a few decibels. "... My future son, he's doing... not bad at all."
He awkwardly rubbed his nose, his ear tips turning slightly red—after all, he was still just a teenager, and suddenly seeing his "future son" made him feel uneasy.
Jiraiya sat cross-legged to one side, his gaze gently fixed on the father and son fighting side by side in the Heavenly Screen. When he saw the figures of past ancestors appear in Boruto's Rasengan, a hint of emotion flashed in his eyes.
(Minato... Kushina...)
He seemed to see the Will of Fire being passed down, like an inextinguishable flame, passed from generation to generation.
"Hey, Naruto!" Jiraiya suddenly stood up, waving his hand, "To celebrate the victory in the Heavenly Screen, Master is treating tonight! Let's go out for a big meal!"
"Really?! Yay--!" Naruto instantly forgot his earlier awkwardness, his azure eyes shining brightly. "I want a super-sized bowl of miso chashu ramen! Triple the chashu!"
Karin adjusted her glasses, a rare look of anticipation appearing in her red eyes behind the lenses. "The seafood hot pot in the Land of Snow is said to be very famous..."
"No problem!" Jiraiya patted his wallet generously (even though there weren't many coins left), "Consider this an early celebration of our little Naruto becoming Hokage in the future!"
The sounds of the three laughing and joking echoed across the snow-covered plain. Behind them, the Heavenly Screen was slowly darkening, and the final image froze on Boruto's confident smile—the radiance of a new era.
In the distant cedar forest, six members of the Anbu silently put away their Kunai. Gekko Hayate coughed twice. "Let's call it a day. It seems... the future of Konoha is going to be quite interesting."
