Traveling through Naruto, I am Uchiha Obito?

As Sasuke fought, he felt the immense gap between himself and the Rubik's Cube. Looking at the face so close to his own, he thought of his older brother, who had always been hailed as a genius.

His opponent's strength, speed, and reaction were all superior to his! In particular, that effortless composure put him under immense pressure.

"Damn it!" Sasuke gritted his teeth, seizing the gap in the Rubik's Cube's defense, feigning an attack with his left hand using a kunai, while secretly gripping a shuriken with his right! This was his last struggle.

Just as he was about to throw it, the Rubik's Cube smiled at him.

"Oh no! He's lying!"

"Pressure, bro."

Rubik's Cube chuckled and joked. Then, with a sudden burst of power, he slammed his right elbow into Sasuke's chest! The fierce force made Sasuke gasp for breath, and the shuriken slipped from his hand! Rubik's Cube's left hand gripped Sasuke's right wrist, which was holding a kunai, like an iron clamp, and twisted it with a reverse joint lock!

"Ugh!" A sharp pain shot through Sasuke, who groaned as his kunai slipped from his grasp. The Rubik's Cube's right foot precisely hooked onto Sasuke's ankle, executing a clean and swift trip!

Pfft!

Sasuke was slammed hard into the dust, his back throbbing with pain, and his vision blurred. He struggled to get up, but the cold tip of a kunai was already lightly poking his throat.

The training ground fell silent instantly.

Sasuke lay on the ground, panting heavily, his Sharingan wide open as he stared at the calm face above him, his expression a complex mix of shock, resentment, and humiliation.

"Quick reflexes and solid physical skills." Rubik's Cube put away his kunai, his tone flat, revealing no praise or criticism. "But he relies too much on his eyes. Prediction is not the same as invincibility."

He stretched out his hand.

Sasuke's eyes were filled with complex emotions. In the end, he politely declined the hand, stubbornly got up, dusted himself off, and turned his face away, but his clenched fists betrayed the turmoil in his heart.

Kakashi appeared on the sidelines at some point, his right eye crinkling slightly. Asuma breathed a sigh of relief, then looked at the cube with a hint of surprise—Jiraiya's disciple was indeed extraordinary. The precise wind-style control that countered the Great Fireball Jutsu, and the instantaneous taijutsu counter, all demonstrated a strength far exceeding that of a genin, or even a chunin.

Naruto rushed over cheering, "Wow! Rubik's Cube is amazing!" Sakura also breathed a sigh of relief, but looked at Sasuke with worry in her eyes.

The Rubik's Cube smiled as it watched Sasuke's stubborn back.

"It was so much fun fighting Erzhuzi! Your little brother is really useful for taking on seven opponents at once!"

The Rubik's Cube watched Sasuke's stubborn back as he got up, without saying a word.

Words of comfort? To Sasuke, whose self-esteem had been utterly crushed by his peers, they would only be a deeper wound. He even suppressed the urge to pat his head.

He gave Naruto a cryptic look.

Naruto scratched his head, looking bewildered, then grinned as if suddenly realizing something, and pounced on Sasuke, grabbing his neck: "Haha! You brat Sasuke, you were spouting all that tough talk before the fight, but you're already giving up so quickly? You're such a loser!"

"Don't touch me! You loser!" Sasuke instantly bristled, his ears turning bright red, and he swung his hand at Naruto's face.

"Haha! I'm getting anxious!" Naruto dodged nimbly, not forgetting to make a face.

"You bastard……"

"Naruto! Quiet down! Stop bothering Sasuke!" Sakura shouted anxiously.

Watching the two instantly wrestle into a tangled mess (mainly Naruto taking the hits while spewing insults), Rubik's Cube's eyes twitched slightly.

(Naruto... he probably understood my hint... right? Oh well, as long as the result is right.)

He knew very well that with Sasuke's current obsessive nature, if he were left to suffer the bitter consequences of failure alone, the negative emotions would not crush him, but would certainly make him more eager to pursue power.

But with Naruto, the carefree "sneaky chicken," and Sakura's concern, those extreme thoughts were at least temporarily diluted and suppressed... until he encountered that treasure-themed rat who showed his younger brother the recording of the clan massacre again...

As his gaze swept over the playful Class 7, Rubik's Cube sighed silently. Only he knew that this noisy yet warm daily routine wouldn't last much longer.

Kakashi and Asuma, who had been watching the match for a long time, walked over. Asuma was about to offer his praise when he noticed that Kakashi hadn't stopped, but instead walked straight to the Rubik's Cube in the center of the arena and stopped opposite him.

Rubik's Cube looked up at the silver-haired Jonin before him. The only eye visible in the other's eye curved into a familiar crescent moon.

"Wow, what a fantastic battle," Kakashi said lazily, his hands in his pockets.

"Watching this has made my hands itch. You weren't really taking it seriously just now, were you?" He tilted his head slightly, his smile deepening. "How about a little sparring session?"

Chapter 11: Battle against Kakashi

"Discussion?"

Upon hearing Kakashi's invitation, Asuma nearly dropped the cigarette he was holding; he showed a surprised expression even before the person in question, Rubik's Cube.

“Hey, Kakashi,” Asuma stepped forward, his tone teasing yet slightly dissuading, “Even though it’s for your beloved disciple, you don’t need to argue with a child, do you?” He glanced meaningfully at Team 7 beside him.

Kakashi didn't answer directly, but instead turned his head and gave Asuma a subtle look. Years of tacit understanding allowed Asuma to instantly grasp the meaning of that look. He raised an eyebrow, swallowed the rest of his words, and turned to look thoughtfully at the Rubik's Cube.

"You mean this kid's strength might be more than that, is that right?"

"How are you feeling? If you're tired, you can take a break," Kakashi said casually.

“No problem, Mr. Kakashi,” the Rubik’s Cube replied calmly.

"You can start anytime."

Although somewhat surprised by the unexpected invitation to compete, Rubik's Cube readily accepted.

He also had his own plans: appropriately demonstrating his strength would save him a lot of trouble—at least it would deter some ignorant "cats and dogs".

……

The sun shone brightly at Konoha's Seventh Training Ground. On the sidelines, the trio of Team 7—Naruto, Sasuke, and Sakura—along with Asuma, who was smoking a cigarette, were intently watching the field.

In the center of the arena, Kakashi Hatake's headband covered his left eye, leaving only his right eye staring directly at the Rubik's Cube in front of him.

After all, he's Jiraiya-sama's disciple; I can't let my guard down. Kakashi thought to himself.

"It's about to begin!" Asuma exhaled a smoke ring. "Kakashi is a tough opponent when he gets serious. I don't know much about Rubik's Cube, but he is Jiraiya's disciple after all, so he should know a lot of Jiraiya's secret techniques."

"Their fight is a valuable opportunity for you, so learn a lot from it."

Asma exhaled a smoke ring and smiled at the three of them, saying...

Before the words were finished, the two figures in the arena suddenly blurred!

boom! boom! boom!

The kunai collided, sparks flying. The Rubik's Cube launched the first attack, but Kakashi precisely blocked it with his kunai. His right eye rapidly captured the details of the Rubik's Cube's movements.

"There's an opening." Kakashi anticipated it instantly. The instant Rubik's Cube's shoulder sank, he shifted to the side, a kunai grazing his forehead! His left hand gripped Rubik's Cube's wrist with lightning chakra, the chakra penetrating!

My wrist went numb, and I couldn't get the Rubik's Cube out of my hand!

The cold, sharp blade pressed against the throat.

"It's over," Kakashi said calmly.

"So fast?!" Naruto exclaimed.

“No…” Asuma squinted.

The Rubik's Cube smiled slightly.

boom!

A puff of smoke drifted by, and the Rubik's Cube in front of Kakashi turned into a piece of wood.

"Substitution Jutsu? When?"

"Earth Release: Earth Flow Wall!" The Rubik's Cube that appeared behind him completed the hand seals! The earthen wall arched up, slamming Kakashi into the pond beside him with a brute force.

"They're actually using a defensive earthwork wall for offense?"

Asma murmured.

Kakashi channeled chakra into his feet, slid back a few steps, and then regained his footing.

Kakashi's eyes turned serious, his fingers hooking the edge of his headband. After all, he was a seasoned Konoha technician, and in just a few exchanges, he had already realized that the boy in front of him was not an opponent that could be dealt with so easily. It seemed that he had to get serious.

"Here it comes!" Sasuke stared intently at Kakashi's next move. For him, who also used the Sharingan, the upcoming battle was what he needed to focus on learning from.

Whoosh! The crimson three-tomoe Sharingan appeared, staring at the Rubik's Cube in front of it.

"Sharingan!" Sakura exclaimed.

Asuma's expression turned serious: "Kakashi is about to get serious."

Kakashi formed hand seals, his speed so fast he was almost a blur! "Water Release: Water Dragon Bullet Technique!" The water in the nearby pool surged into a roaring water dragon, rushing straight at the Rubik's Cube!

Demon Fang showed no fear, and facing the water dragon, he formed hand seals and unleashed "Fire Release: Dragon Fire Technique!" A blazing fireball erupted, but it arced and slammed into the remnants of the earthen wall in front of him!

boom!

The fireball explodes and bounces back! The burning clods of earth transform into a tricky rain of fire that engulfs Kakashi! The power increases dramatically!

"Use Earth Release as a springboard to enhance the fire attack! Combine ninjutsu!" Asuma spoke rapidly.

"The Sharingan's visual ability can see the direction of an attack, but the Rubik's Cube's attacks are too dense; Kakashi can't dodge them!"

Kakashi's Sharingan spun rapidly. "Fire Release: Phoenix Flower Technique!" Dozens of condensed fireballs precisely blocked the most threatening burning clod of earth.

Bang bang bang!

The flames suspended in the air exploded instantly and fell to the bottom of the pool. Kakashi's Phoenix Fire cleverly used the shockwave from the collision to deflect the direction of the fire-covered earth block!

The blazing fire rain collided violently with the water dragon, sending up large plumes of steam in the training ground.

hiss--! ! !

Thick white fog instantly engulfed most of the training ground, and the four people watching from the sidelines lost their sight.

"I can't see it!" Naruto exclaimed anxiously.

Sasuke activated his Sharingan and stared intently at the thick fog.

In the heart of the dense fog, Kakashi, with his Sharingan, made the first move, his left hand wielding the Lightning Blade with a series of hisses! — "Lightning Blade!" Blue and white lightning tore through the thick fog.

"Raikiri!? Kakashi is taking this seriously?" Asuma said in a deep voice.

Raiche tore through the last few meters of thick fog, reaching right next to the Rubik's Cube.

"Successful!"

Kakashi thought to himself.

At that very moment, an accident occurred.

In the thick fog, Rubik's Cube's original spiky short hair instantly sprouted a ring of long, black hair as hard as steel needles! Like a hedgehog's armor suddenly unfolding, it protected Rubik's Cube!

Ninja, needle Jizo!

clang--!!!"

A deafening metallic clang rang out! The raging lightning of the Raikiri pierced the steel-hardened black hair! Blue and white electric snakes tore at it frantically, yet couldn't penetrate the incredibly tough defense! The immense impact cracked the ground beneath the cube's feet, but his body remained firmly protected by the hair shield!

"Jiraiya-sama's signature technique?" Asuma's eyes flashed with brilliance. "But this defensive power... it can actually block the Lightning Blade... how is that possible?"

Kakashi's Sharingan pupils contracted, momentarily shocked by the resilience of this Jizo's defensive power!

In the brief moment that Kakashi's attack was slightly hampered by the Jizo needle defense, the ground beneath the Rubik's Cube's feet silently softened and collapsed!

Under the cover of Needle Ksitigarbha, he had already silently completed the hand seal.

"Earth Escape·Yellow Spring Marsh!"

The spot where Kakashi was standing instantly turned into a sticky mud pit! The sudden feeling of sinking made him lose his balance, and the lightning of his Lightning Blade became slightly disordered due to his swaying!

An even more deadly attack came from the side! A figure rapidly coalescing from the black hair separated from the Rubik's Cube's needle Jizo attacked from Kakashi's side and rear—a clone?

The clone formed hand seals, its black hair splitting into several strands, and precisely wrapped around Kakashi's ankles, which were restricted in their movements due to being stuck in the mud!

"Hair manipulation?!" Kakashi's heart skipped a beat. Although his Sharingan had detected the appearance of the Earth Clone and the trajectory of the tangled hair, his body was sinking into the mud, his center of gravity was unstable, and the stiffness of his Lightning Blade made dodging extremely difficult! He barely managed to twist his body, trying to cut the tangled hair with a kunai, but the black hair was exceptionally tough, and the kunai made a hissing sound when it cut, making it difficult to sever! His ankles were tightly bound and tightened by several strands of tough hair, giving him a feeling of being bound!

It's now!

After the Rubik's Cube clones entangled Kakashi, it immediately released the Needle Jizo, and its crimson three-tomoe Sharingan suddenly opened! It locked onto Kakashi, whose movements were slowed by the mud and hair binding him!

Kakashi's Sharingan also met those equally crimson eyes with three tomoe!

"How can this be?"

Kakashi's thoughts paused briefly. Those eyes? And that face? How could there be so many coincidences in the world? What exactly is the relationship between this boy and Obito?

The Sharingan of the Rubik's Cube magnified this flaw infinitely! His right hand, which had been gathering power, had already condensed a rapidly spinning, buzzing, azure chakra sphere—this was a Rasengan infused with wind attribute nature transformation!

The Rasengan in his right hand stopped abruptly just before it was about to hit Kakashi. Although it didn't hit his main body, Kakashi was blown away by the powerful wind pressure of the Rasengan.

Kakashi managed to adjust his posture in mid-air, bracing himself with one hand on the ground, and slid backward for several meters before stopping, looking quite disheveled.

"What's going on? That power... I can also make the Rasengan, but this power is clearly different."
