"Not bad at all. Beating Hanzo came with quite the reward."
Uha's eyes lit up as he glanced over the system prompt. "Rare spiritual pressure experience points, and even a Reaper's soul?"
In essence, spiritual pressure functioned similarly to chakra. The higher one's spiritual pressure, the greater their strength. When it reached a certain level, even standing near them could overwhelm weaker beings.
But the most crucial reward was the third item the Reaper's Soul.
With it, Uha could break the boundaries between Hollow and Shinigami through the system, making a tremendous leap in power across dimensions.
"Redeem."
As soon as the thought crossed his mind, Uha felt a subtle change ripple through his body.
The black wings behind his back vanished as his Resurrección state receded. The pale tone of his skin returned to a healthy hue. Even the hollow hole at his clavicle was filled in. His aura surged, becoming even more powerful than before.
"System, open the panel," he muttered.
A translucent interface flickered into view before him.
Dimensional Antagonist System
Host: Uha
Spiritual Pressure: Lv4 (1000/5000 – Moderate)
Spiritual Core: Dark-Winged Archdemon (Resurrección)
Zanpakutō: None
Swordsmanship: Excellent
Hand-to-hand Combat: Proficient
Shunpo (Flash Step): Proficient
Kido (Demon Arts): Beginner
Items: Black Cloak, Dimensional Cube
"So, now that I've fused with a Shinigami soul... I can wield a Zanpakutō?"
Uha narrowed his eyes slightly, thinking to himself, "I can even use Kido now. Not that it's terribly useful at the moment, but it definitely expands my arsenal."
Not far away, hidden in the jungle, Black Zetsu was in complete disbelief.
He had watched the entire scene unfold.
First, Nagato was completely won over by Uha.
Then Obito was swayed too.
And now, him Black Zetsu, the third son of the Chakra progenitor was left utterly alone?
In less than a day, both of his key players had defected?
How was the Eye of the Moon plan supposed to proceed?
How was he supposed to resurrect his mother?
As for Uha's origins, he had already begun to suspect the truth.
He couldn't sense any chakra from this man at all.
And that ominous black-winged form... the power system was clearly not chakra-based.
If his guess was right...
This man, like his mother Kaguya, was truly an otherworldly being.
Remembering the tales Kaguya once shared about the terrifying Ōtsutsuki clan, Black Zetsu immediately felt that Uha posed a similar threat level.
"I need to leave."
Black Zetsu's expression turned grim.
"With Nagato and Obito both lost, I'll have to find new candidates for the Eye of the Moon plan. I'll also need to retrieve Madara's Rinnegan... and if worst comes to worst, I'll have to resurrect him early."
A being who could kill Hanzo in an instant was virtually unbeatable in single combat.
And his abilities mysterious and devastating.
That spear-like technique had lopped off Hanzo's arm with a single sweep.
And that energy attack, akin to a Tailed Beast Bomb, had bent space and interrupted Obito's Kamui.
Every technique he had displayed was beyond comprehension.
If Uha had any additional sensory powers capable of detecting him...
That would be catastrophic.
Suddenly, a voice echoed faintly behind him.
"Black Zetsu, the Ōtsutsuki clan's foolishly loyal mama's boy. Where you rushing off to? Come on, stay for a chat."
"Damn it, he found me?!"
Black Zetsu panicked and began sinking into the ground.
He even knew my true identity?!
And what did he just call me? 'Foolishly loyal mama's boy'?
He didn't fully understand the insult, but he had a bad feeling it involved his mother Kaguya.
Not just that. This man knew everything about Nagato, about Obito, even Madara's manipulation of Obito. He knew it all.
An insider leak?
Impossible.
It had to be some unique ability.
Omniscience?
Foresight?
Either way, it was terrifying.
Black Zetsu's fear spiked, and he tried to activate his Mayfly Technique to escape immediately.
But Uha calmly raised his hand.
"Bakudo #61..."
"Six Rods Light Prison!"
Shing!
Six glowing rods appeared out of thin air and locked tightly around Black Zetsu, freezing him in place.
But before they could fully seal him, Black Zetsu slipped out of his White Zetsu host and melted into a pool of black goo, vanishing into the earth.
In mere moments, he disappeared without a trace.
"He got away? That coward," Uha muttered, shaking his head.
"A pity. I was hoping to get some intel about the Ōtsutsuki clan from him. Ran off faster than a spooked rabbit."
Black Zetsu may not have inherited Kaguya's full powers, but his escape abilities were truly absurd.
As a manifestation of her will, most forms of attack were useless against him. Only a proper seal could stop him.
"I hope you don't go stirring up more trouble. Otherwise, I'll lock you in the void. Let you savor an eternity of solitude," Uha murmured coldly.
In the following month, Uha, Nagato, Obito, and Konan crushed the remnants of Hanzo's conservative faction.
Nagato turned his late friend Yahiko into the Deva Path, establishing him as the symbolic leader of Amegakure.
The rest of the time, Uha didn't pursue system missions.
Instead, he focused on helping Nagato, Konan, and Obito grow stronger for the sake of future plans.
And the best training method? Real combat.
They sparred against Uha constantly, day and night.
Before long, the trio's growth reached astonishing levels.
One Year Later - Amegakure
Steel towers loomed across the village skyline. A complex drainage system hinted at their modest industrial capabilities. Rain fell steadily from the sky, as always.
In a vast underground chamber, a black cube sat quietly.
This was the Dimensional Cube the very artifact that brought Uha into the world of Naruto.
Though only two meters in size on the outside, its internal space was thousands of times larger. Inside, time seemed to flow differently.
Unless Uha allowed it, or unless someone surpassed the cube's dimensional threshold, it was nearly impossible to damage its internal space.
And from the outside, it was unbreakable.
Perfect for imprisoning someone like Black Zetsu.
Inside the cube, the space was blinding white.
Uha and three figures were locked in intense battle.
After thirty minutes, the fight came to an end.
Looking at the three drenched and panting, Uha couldn't help but smile.
"Monsters, all of you. Less than a year, and you've surpassed my base form already."
Obito and Konan had reached Kage-level. Nagato, using Deva Path, had climbed into the realm of super-Kage.
Against all three, even Uha's Resurrección form now required effort to suppress them.
And it was worth noting this was just training, not a fight to the death.
Given time, especially with preparation...
Konan's infamous "Angel's Tears" cough
Her six hundred billion explosive tags might overwhelm even Uha in Resurrección form.
Nagato was still incomplete, with only the Deva Path assembled. The other five hadn't yet been gathered or prepared, so his power was still below canon levels.
After giving Konan and Nagato a few well-earned compliments, Uha turned to Obito with a serious look.
"Obito, your growth has been impressive too. Your Wood Release and Fire Release ninjutsu are solid. Kamui makes you nearly invincible. But offensively, you're still lacking."
"That's just it..." Obito muttered, frustrated. "Kamui only has two functions phasing and teleportation. I can't push it any further."
"No, there is a way. A method that can not only enhance your space-time ninjutsu, but awaken new powers tied to your bloodline."
Obito blinked. "Wait... you mean"
Uha smiled and nodded.
"That's right. I'm going to Konoha... to retrieve your other Sharingan."
