Naruto: I Have Doraemon

"Forget it, with Naruto in Konoha, the battle is over. Nothing serious will happen."

Uchiha Itachi muttered to himself as he watched Susanoo dissipate in the distance. He calmed down and continued walking toward a weak point in the village's barrier that he was familiar with.

A Moment Later

Itachi's steady pace suddenly halted, his scarlet Sharingan eyes narrowing as he gazed into the tranquil forest ahead.

In his line of sight, the forest appeared peaceful. Squirrels scurried through the trees, and birds chirped melodiously, flitting from branch to branch. Occasionally, a startled animal would dart away as Itachi's presence disturbed the calm, but for the most part, nature carried on as usual.

Despite the serene surroundings, Uchiha Itachi stopped in his tracks, uncharacteristically wary.

Whoosh, whoosh, whoosh...

Without warning, several kunai were hurled from the depths of the forest, cutting through the air with great speed and precision, aimed directly at Itachi.

Itachi reacted effortlessly, drawing two kunai of his own and launching them at the oncoming projectiles. The weapons collided midair with a series of sharp clangs, deflecting the enemy's kunai and sending them tumbling harmlessly to the ground.

"Come out," Itachi commanded, his voice cold and unyielding as he fixed his gaze on the branches of a nearby giant tree.

"Long time no see, Itachi..."

From behind the massive trunk of the tree, Sasuke emerged slowly, his own Sharingan glowing red as he locked eyes with his elder brother.

"You... Sasuke?"

Itachi's pupils dilated in shock, his normally stoic expression replaced by one of surprise and confusion.

"Is it such a surprise?" Sasuke said, a mixture of emotions flickering across his face. "I'm just as shocked. I didn't expect to find you here in Konoha. And look at you—you also have the Eternal Mangekyō Sharingan."

He paused, his voice heavy with emotion. "This time, Itachi, you don't need to be the older brother who sacrifices everything."

"Are you really Sasuke? What on earth is going on here?"

Itachi's mind raced as he studied his younger brother. There was no doubt that this was Sasuke—his Sharingan confirmed it was no mere transformation or trickery.

"Of course, I'll explain everything to you," Sasuke replied, his tone firm. "But before that, I want to ask you something."

He stepped forward, his eyes blazing with intensity. "In your heart, what kind of existence am I?"

Sasuke's voice rose, slightly out of control. His emotions boiled over as he confronted the man who had shaped his life so profoundly.

In his world, Sasuke's life had been dominated by Itachi. Even after Itachi's death, his influence persisted through Naruto, who carried out the plans Itachi had laid. If not for Kabuto's interference, Itachi's Kotoamatsukami would have determined Sasuke's future completely.

Although Sasuke eventually embraced Itachi's will and continued to protect Konoha, it didn't mean he was without resentment.

"What kind of existence?"

Itachi sighed deeply, his face softening slightly. "It seems you truly are my foolish little brother, Sasuke. And it seems the world has changed yet again."

"Really...

That attitude of yours again!

Even in another world, you remain so self-righteous.

Fine then! Let me show you how much I've grown."

Sasuke's fury exploded at Itachi's dismissive words, especially the familiar phrase "foolish little brother." His left eye, the Rinnegan with six tomoe (Liugouyō), began to glow ominously, and the wind around him stirred as his Chakra flared.

"Rinnegan!!!

"You... You have the Rinnegan? How is this possible?"

Itachi's calm demeanor cracked as he stared at Sasuke's glowing Rinnegan, his voice filled with disbelief.

"So, there are things that can surprise even you, Itachi?" Sasuke taunted, a smirk tugging at the corners of his mouth. "Don't worry, I'll explain everything...

But only after I've taught you a lesson."

Sasuke raised his hand, his voice commanding and filled with determination.

"Susanoo!"

Sasuke smiled with satisfaction and let out a low, disdainful laugh as he quickly formed the complete purple body of Susanoo.

In just a single breath, a 200-meter-tall purple full-body Susanoo appeared in front of the stunned Uchiha Itachi, standing like a warrior god.

The armor on its back extended into wings, clearly capable of flying into the sky.

The double swords at its waist were so long that they could easily split mountains and rivers.

This was the perfect Susanoo, beyond the fourth stage of Uchiha Itachi's version.

Standing within the crystal on Susanoo's forehead, Sasuke looked down at Uchiha Itachi, who now appeared as small as an ant, feeling a great sense of satisfaction.

It was true that Sasuke wanted to teach Uchiha Itachi a lesson, but more than that, he wanted Itachi to see his growth and be able to communicate as equals.

Otherwise, he wouldn't have used so much Chakra to unleash Susanoo.

Though Naruto had helped him recover a portion of his Chakra, it wasn't enough to maintain the full-body Susanoo for long.

Of course, showing off a little was part of it too.

"Underestimated, huh? Your strength is indeed beyond mine... but..."

Uchiha Itachi gazed up at the giant Susanoo, speaking softly as his Eternal Mangekyō Sharingan glowed scarlet in his eyes.

"...Although I admit that you're very strong, as a brother, I will never admit defeat so easily!"

With those words, Uchiha Itachi's red Susanoo began to emerge, its form taking shape.

This time, Itachi was using his full power, and soon, a 80-meter-high Susanoo stood opposite Sasuke.

[The Gap Between the Two Susanoos]

The difference between the fourth-stage Susanoo and the perfect Susanoo was enormous.

Although Itachi's Susanoo lacked the two pairs of wings that Sasuke's had, and its height only reached Sasuke's Susanoo's thigh, it was still a powerful force.

Equipped with the Ten Fist Sword and Yata Mirror, Itachi's red Susanoo, with one sword and one shield, was formidable.

"Is this all you have?" Sasuke taunted, his voice full of confidence. "Well, then let me begin..."

With a condescending roar, Sasuke controlled Susanoo and delivered a massive punch.

He was only showing off his strength and had no intention of using weapons.

Itachi, ever cautious, reacted quickly. He transformed his shield into the Yata Mirror, blocking the attack.

When their fists collided, a terrifying shockwave erupted, throwing everything in its path at incredible speed.

The wind pressure was as intense as a level-10 typhoon, and it swept across Konoha Village in an instant.

Sasuke saw that his punch had been blocked by Itachi's shield, so he redirected his other arm to strike Itachi's Susanoo from a different angle.

Although Itachi's physical strength wasn't as great as Sasuke's, his battle sense was incredibly sharp. He quickly retreated to avoid the blow and countered with a punch aimed at Sasuke's legs.

Sako and Naruto, who were nearby, noticed the movements of the two giant Susanoos.

"Is that Susanoo Sasuke's?" Sako asked, observing the massive figures. "The other one... that's Itachi! That guy actually returned to the village..."

After seeing the two Susanoos, one large and one small, Sako immediately recognized the identities of the two Uchiha brothers.

"These two are really something," Naruto muttered, looking at the Susanoos clashing. He immediately understood that this was just a playful fight between the two brothers, a classic "tsundere" battle.

Sasuke didn't take Naruto's comment seriously. He knew that neither he nor Itachi would bring the fight to Konoha.

However, Sasuke also understood his own feelings—there was more than just anger fueling this battle.

As Sako gave the order to calm the village, a flash of white light appeared at the battlefield, and a figure materialized.

The figure had pale skin, long light blue hair tied in a high ponytail, and two dots on his forehead. His white eyes, lack of eyebrows, and forehead protector-like horns marked him as an outsider.

Dressed in white clothing, he carried a red light fishing rod, which he held with great poise.

The figure who appeared was none other than Ōtsutsuki Urashiki, who had arrived a bit late.

"Uchiha Sasuke?? Who is that guy?"

As soon as Urashiki appeared, he saw the two massive Susanoos and grinned.

"Urashiki, you're finally here!"

Sasuke quickly noticed Urashiki and immediately dismissed Susanoo to conserve Chakra. He glared at Urashiki fiercely.

"Is he an enemy?"

Although Uchiha Itachi wasn't sure what was going on, he instinctively followed Sasuke's lead, activating his Susanoo and eyeing Urashiki warily.

"Is this an enemy?" Itachi asked Sasuke, cautious but unsure of the new arrival.

"Forget it, with Naruto in Konoha, the battle is over. Nothing serious will happen."

Uchiha Itachi muttered to himself as he watched Susanoo dissipate in the distance. He calmed down and continued walking toward a weak point in the village's barrier that he was familiar with.
