Naruto:The System's Shadow

The ninja paused, his expression suddenly darkening. He raised his hand, and three shuriken shot towards Kaito, clearly a well-prepared attack.

The shuriken pierced Kaito's body without resistance, and his form dissolved into a puff of white smoke.

A Clone!

Alarmed, the ninja didn't bother concealing his intentions any longer. He roared, "Byakugan!" Instantly, the veins around his eyes bulged, and his pupils turned completely white – the Byakugan, one of the Three Great Dojutsu.

"Fire Style: Fireball Jutsu."

The moment he activated his Byakugan, a massive fireball hurtled towards his back. Unable to react in time, he scattered chakra through his hands and spun rapidly.

"Rotation!"

A full 360-degree defense deflected the enormous fireball. Kaito's figure appeared on a nearby tree trunk. He thought to himself, "The defense is pretty good. Sharingan, activate!"

In an instant, his pupils turned blood red, and the three eerie tomoe within began to spin slowly. He stared intently at the Rotation below, gripping a kunai tightly in each hand.

This was nothing like the spars in the clan where he could afford to hold back. This was a life-or-death battle. A moment's distraction could be the difference between survival and death. He couldn't afford to conceal his power. Besides, the ninja below wasn't weak; Kaito estimated him to be at least a top-tier Chunin.

"One… two… three…"

Kaito counted silently. The moment he said "three," the Rotation stopped, and he shot down like an arrow.

The two kunai in his hands had mysteriously multiplied to six. He flicked his wrist, and they flew out, each trailing a chakra wire tipped with an explosive tag.

"Detonate!"

The moment the kunai landed at the ninja's feet, Kaito detonated the tags. A series of deafening explosions rocked the area.

A figure leaped out from the center of the blast. Kaito sneered and completed the hand seals. "Just waiting for you. Fire Style: Fire Dragon Flame Bullet!"

A massive column of fire erupted, splitting into three dragon-shaped streams that roared towards the ninja.

"A B-rank jutsu? How… This kid…" The ninja gritted his teeth and unleashed all the chakra from his tenketsu points, enduring the flames as he charged towards Uchiha Kaito below.

"Eight Trigrams: Vacuum Palm!"

Intense chakra gathered in his palm. He had decided to end this quickly. The kid's intelligence and the power of his jutsu were astonishing. He feared that the longer this dragged on, the more danger he'd be in.

As he approached Kaito, he saw the blood-red Sharingan with its spinning tomoe. It sent a chill down his spine and strengthened his resolve to kill the boy. With the three-tomoe Sharingan at such a young age, his talent was terrifying; he couldn't be allowed to grow any further.

The powerful palm struck Kaito's body, but it didn't feel solid. It slammed into the earth, the force of the impact cracking the ground.

"What… I didn't hit? Body Flicker? Replacement Technique? When did he do the hand seals!" Countless thoughts flashed through the ninja's mind.

Just then, strands of silver chakra wire appeared around him, suddenly tightening and binding him securely.

Behind him, Kaito revealed himself, holding the chakra threads. "I just learned this from Madara. Fire Style: Fire Dragon Jutsu."

A large burst of flame erupted from his mouth, flowing along the chakra threads and engulfing the ninja.

A scream echoed through the forest as the ninja fainted in the inferno, his life force rapidly fading.

Kaito timed it carefully and extinguished the flames. He still had questions to ask. He couldn't kill him yet.

A bucket of water splashed over the ninja's head, and he groggily awoke to find himself tied to a tree with chakra threads, barely able to move.

Seeing that he was awake, Kaito immediately asked, "Tell me everything. You know you can't hide anything from the Sharingan."

Resigned to his fate, the ninja sighed. "I never thought I would be defeated by a brat after so many years roaming the Warring States. I'll answer, but I have a question: how did you dodge my Vacuum Palm at the end? I could see with my Byakugan that you didn't have time to weave any seals."

Kaito chuckled. "So that's it. It's simple. I didn't do any hand seals. You just missed."

The ninja became agitated. "Impossible! I have the Byakugan. How could I miss? Wait… an illusion. That's right, it must have been an illusion! But when did I fall under it?"

The ninja frowned and thought hard. He suddenly remembered when he charged towards Kaito and saw the three-tomoe Sharingan in his eyes.

"Was it then? I didn't even notice!"

Seeing the ninja's dejected expression, Kaito scowled. He kicked him in the leg, saying angrily, "I don't have time for this. Tell me. What's your objective? Why did you trick the defense ninjas into leaving the compound?" He wanted to kick him in the stomach, but he was too short to reach.

"I'm a Hyuga spy. After we broke through the Uchiha's defenses, we planned to join the battle and encircle the Uchiha with the Senju, but our clan leader was worried about the cost, considering the Uchiha clan's strength on the main battlefield. Our Hyuga clan is a great clan, but we're still much weaker than the Senju and Uchiha. We couldn't afford too many casualties on the main battlefield."

The ninja knew about the Sharingan's hypnotic abilities and started to talk. He figured it was better to confess than have his ancestors' names dragged out by the Sharingan's influence.

Kaito frowned slightly. "Get to the point."

"Alright, in short, my clan didn't want to wade into the muddy waters of the main battlefield, so we came up with a plan. We sent me to impersonate an Uchiha clan member to request reinforcements and lure away the defense ninjas from the compound. Then, we would secretly send an elite team to sneak into the Uchiha compound under the cover of darkness and eliminate the Uchiha clan's new generation."

"What?" Kaito finally lost his composure, gasping. The Hyuga clan was ruthless! This was nothing less than a plan to destroy their lineage. If they succeeded, the entire Uchiha clan would go mad.
