Rebirth of Uchiha Shisui

Year 46 of the Konoha era, the first year of the Third Shinobi World War, within the borders of the Land of Fire.

"Shisui, hurry up! I just received a distress signal from Jōnin Mimura Hamaki. Higashishinin, a Jōnin from Iwagakure, has led a force of 1,000 earth-style users to invade and has already reached the vicinity of Kannabi Bridge. We must get there to provide support as quickly as possible."

As the Konoha Chūnin spoke, he glanced back at his companion, only to find Shisui Uchiha standing still, showing no intention of following him.

"I apologize, Akira Shimura. I have also just received a message from my clansmen in the Uchiha. They have been ambushed by Iwagakure as well. However, they are not near Kannabi Bridge, and I must go to support them now."

The Shisui Uchiha of the present was not the naive, kind-hearted young man from the original story who would sacrifice everything for the village; his body housed a complex soul.

One half was a soul that had transmigrated here, while the other was the original soul that had remained within Shisui's body.

The two had merged to become the brand-new Shisui Uchiha of today.

To avoid being discovered, he had not shown any abnormalities over the past few years, dutifully following the life trajectory of Shisui Uchiha.

Yet, Shisui knew that the ultimate result of continuing this way would be Danzō Shimura stealing his right eye, followed by him digging out his left eye to gift to Itachi Uchiha, and finally throwing himself into the Naka River to commit suicide, all to facilitate the awakening of Itachi Uchiha's Mangekyō Sharingan.

Shisui was unwilling to accept such a fate, but he had simply never found the right opportunity to change it.

The Battle of Kannabi Bridge was not only the turning point of the Third Shinobi World War but also the pivot for the fate of the Uchiha clan for decades to come. Shisui was prepared to use this critical juncture to do something to alter his own destiny.

"But Lord Mimura Hamaki is the supreme commander of the frontline defense forces. To abandon your post and defy orders like this—you are not fit to be a ninja."

Facing Akira Shimura's criticism, Shisui did not retort. In this life, he knew clearly that this so-called companion was merely a person sent by the Shimura clan to monitor him.

And their clan leader, Danzō Shimura, was the very man who would later ruin his entire life.

"Those who cannot protect their comrades are not fit to be called ninjas."

"Furthermore, when did the affairs of our Uchiha clan ever become something for you, Akira Shimura, to point fingers at?"

Having lived a second life, Shisui Uchiha had observed Konoha for seven years with the mindset of an adult; how could he be deceived by such hypocritical lies again?

At this moment, Shisui's former companions felt he was a complete stranger.

"You, Shisui Uchiha, are you trying to rebel?!" a humiliated Akira Shimura shouted.

"Shisui Uchiha, if you continue to be so stubborn, I will have no choice but to tell my uncle everything and have you severely punished."

The one chiming in from the side was Shisui Uchiha's other teammate, Kamii Sarutobi. Both he and Akira Shimura were Shisui's teammates on the surface, while secretly monitoring his every move.

The village claimed that this arrangement was made to honor the contributions of Kagami Uchiha, specifically to replicate the friendship that once existed between Kagami Uchiha, Hiruzen Sarutobi, and Danzō Shimura.

Thinking of how they were using his late grandfather as a prop, Shisui's heart burned with even greater rage. Now, he only wanted to get away from these two disgusting individuals immediately.

Just as Shisui prepared to leave, a kunai suddenly shot in from the left, aimed directly at his vitals.

However, for an Uchiha with the Sharingan, the flight trajectory of a kunai was easily seen through. Shisui Uchiha, famous in Konoha for his Body Flicker Technique, dodged the attack with ease.

"Shisui Uchiha, don't you dare leave, or don't blame us for being impolite."

It was Akira Shimura who had launched the sneak attack, while Kamii Sarutobi also assumed an offensive stance.

"Attacking your own comrade—is this what Danzō Shimura taught you? You are not fit to be a ninja."

At this moment, old grievances and new hatreds surged in his heart. Shisui Uchiha no longer wanted to suppress his inner fury; he was going to teach these two bastards a lesson.

"Fire Release: Great Fireball Technique."

Shisui Uchiha completed the five hand seals for the Great Fireball Technique in just one second. The flames he exhaled formed a fireball taller than a man, flying rapidly toward Akira Shimura and Kamii Sarutobi.

"You dare to fight back? Water Release: Iron Bullet!" Akira Shimura used a C-rank water-style ninjutsu, attempting to neutralize Shisui's Great Fireball Technique.

Kamii Sarutobi switched from defense to offense, directly unleashing a C-rank earth-style ninjutsu in an attempt to launch a sneak attack.

"Earth Release: Earth Dragon Submersion Technique."

Facing their counterattacks, Shisui only found it laughable.

"You have no idea how ridiculous your actions are in front of these eyes."

When Shisui opened his eyes again, his scarlet irises fixed upon the small movements of Akira Shimura and Kamii Sarutobi. A pair of ink-black three-tomoe were slowly rotating within his eyes, and his powerful ocular chakra radiated outward without restraint.

"Caught you, you traitor."

Relying on the stealth capabilities of the Earth Dragon Submersion Technique, Kamii Sarutobi moved rapidly beneath Shisui Uchiha's feet and grabbed his ankle.

"Earth Release: Headhunter Technique."

Just as Kamii Sarutobi thought he had successfully trapped Shisui Uchiha, he discovered that what he was holding was merely a wooden log.

"Substitution Technique? When?" Kamii Sarutobi exclaimed in shock.

"Is this enough to surprise you? What gave you the confidence that you could defeat me?"

Shisui Uchiha appeared to the side, looking at the two fools in their disheveled state, and continued to weave hand seals.

"Next, I will let you witness the technique I have newly developed: Phantom Body Flicker Technique."

The moment the seals were completed, three identical phantoms appeared beside Shisui Uchiha. Then, all four Shisui Uchihas drew their kunai and charged toward Akira Shimura and Kamii Sarutobi.

"Don't panic! There is only one real body!" Akira Shimura, having just caught his breath, shouted to warn Kamii Sarutobi on the other side, while also trying to bolster his own courage.

"Is that so? Then open your eyes wide and watch closely." All four Shisui Uchihas spoke in unison.

The Phantom Body Flicker Technique, the origin of the title "Body Flicker Shisui," was not merely because this technique could create multiple phantoms to confuse the enemy.

These phantoms not only attacked the opponent alongside the real body, dealing the same amount of damage, but they also did not disappear when struck; the opponent could not distinguish the real body through traditional means.

Even if Shisui's real body were identified, he could shift his true form among these phantoms, preventing the opponent from ever locking onto him.

This was the true power of the Phantom Body Flicker Technique.
