The air was thick with residual chakra, humming with the remnants of an event that had reshaped reality itself. The chamber, once filled with the raw turbulence of Ryūsei's transformation, had fallen into an eerie stillness. Tsunade stood a few feet away, arms crossed, her golden eyes locked onto him—not with fear, but with awe and calculated curiosity.
Something had changed.
No—everything had changed.
Ryūsei stood at the heart of it all, his body visibly the same yet profoundly different. His presence felt more solid, more absolute, as if the very fabric of space bent to accommodate him.
Tsunade knew power. She had witnessed the might of the strongest shinobi in history, had inherited the legacy of the Senju, and had fought beside legends. But this—this was something entirely new.
Her eyes were drawn to his own.
The Eyes of a God
His Byakugan, once a testament to clarity and foresight, had evolved further. A faint golden hue rimmed its edges, making it feel almost ethereal—as if it now saw deeper into the world's truths.
But that wasn't all.
As she watched, the Byakugan flickered—and vanished.
In its place, a golden Rinnegan appeared. It wasn't the usual deep purple of its predecessors, but a shimmering gold, adorned with six magatama symmetrically etched into its design. The sheer presence of those eyes sent a pulse through the air, an unspoken declaration of dominance.
Tsunade's breath caught. "You can… switch between them?"
Ryūsei blinked once, and the Byakugan returned. Another blink, and it was the Rinnegan once more.
"At will," he confirmed.
Tsunade exhaled slowly. "And what does it mean?"
Ryūsei touched his forehead lightly, as if tracing the changes he himself was still adjusting to.
"My bloodline is whole now. Before, I carried the legacies of the Hyūga, Uchiha, Senju, Uzumaki, Kaguya, and the Moon Ōtsutsuki separately. They coexisted, but they remained distinct. When I fully mastered Yin-Yang Release, it acted as a catalyst. My chakra seed reacted, pulling everything together, and in that moment…" He looked at her, his gaze calm yet absolute.
"I became something new."
The Test of Power
Tsunade studied him for a long moment before stepping forward. "Then let's see what 'new' actually means."
She raised her hand, chakra flaring around her fist. It was a silent challenge—show me.
Ryūsei smirked. "Alright."
Without warning, Tsunade moved. She was fast—one of the fastest in close combat. Her superhuman strength alone had made her one of the most dangerous kunoichi alive.
Her fist shot toward him, a blow that could shatter mountains.
But Ryūsei… didn't move.
The moment her attack connected, a golden pulse erupted from his body—Genesis activated.
The impact never came. Instead, Tsunade felt her own chakra redirected. Her muscles, which should have been pushing forward with crushing force, suddenly relaxed against her will. It wasn't an external interference—it was as if her body itself had readjusted to avoid harming him.
She leapt back immediately, eyes narrowing. "You rewrote my attack?"
Ryūsei flexed his fingers, watching the golden energy dissipate. "Not just that. I adjusted your muscle tension, corrected your chakra flow, and reduced the burden of exertion." He lifted his hand, watching the golden glow dance between his fingers. "Genesis isn't just healing—it's refinement."
Tsunade rolled her shoulder, testing it. Her movements felt smoother, more precise.
She smirked. "Alright, what about destruction?"
Ryūsei's golden Rinnegan pulsed.
The Power of Annihilation
The air itself seemed to contract as an invisible force spread from his body. A faint black aura crackled around him—God of Destruction.
Tsunade felt an overwhelming sense of obliteration radiating from him, as if the very atoms of existence trembled under his gaze.
He turned toward a boulder on the far end of the chamber. Without a single hand sign, he extended his fingers—and snapped.
Silence.
Then—
The boulder ceased to exist.
There was no explosion, no disintegration—it simply vanished. Like a concept erased from reality itself.
Tsunade's stomach tightened. "That's not just destruction."
Ryūsei lowered his hand, his expression unreadable. "No. It's erasure."
Unlike traditional destruction techniques, which relied on force or disintegration, this technique removed the very idea of the target from existence. It didn't leave behind dust, fragments, or energy traces. It left nothing.
Tsunade exhaled. "So, one power restores, and the other… removes."
Ryūsei nodded. "Two sides of the same coin."
The Revelation
Tsunade crossed her arms, watching him carefully. "And how does it feel?"
Ryūsei was silent for a moment before he finally answered. "Balanced."
For the first time in his life, there was no conflict in his chakra, no opposing forces pulling him in different directions. His abilities weren't just tools—they were extensions of his very being.
Tsunade smirked, stepping closer. "Well, at least you didn't turn into some emotionless alien."
Ryūsei laughed. "No, I think I'll keep my personality, thank you."
She playfully punched his arm, though much lighter than usual. "Then what's next?"
Ryūsei turned his gaze upward. His vision now stretched beyond what he had once thought possible. He could sense the ripples of power across the world, the shifting fate of nations.
"The war is coming," he murmured. "And the world is changing."
Tsunade tilted her head. "Because of your new power?"
Ryūsei's golden Rinnegan pulsed.
"No," he said simply. "Because we decide what the future will be."
And as those words left his lips, somewhere in the distant cosmos—something stirred.
As if his evolution had been noticed.
By beings that had watched from the shadows since the dawn of time.
