The chamber still crackled with lingering energy from Ryūsei's transformation. The walls hummed with residual chakra, the very air thick with power, like an ancient force had been awakened. Tsunade stood in the center, golden eyes sharp as she gazed at Ryūsei, her body still adjusting to the monumental shift that had just occurred.
She had seen him evolve, transform into something beyond human comprehension—a being on the threshold of divinity. But even now, as he stood before her, she knew he was still her Ryūsei.
And yet… she could feel it. He wasn't done yet.
A Dangerous Gift
Ryūsei stepped forward, raising his hand. A small, shimmering drop of his blood hovered between them, glowing with golden light.
Tsunade frowned, crossing her arms. "And what exactly are you doing now?"
He smiled—a knowing, almost mischievous smile. "Take it as a token."
She arched a brow. "A token of what?"
Instead of answering, he cupped her chin gently, tilting her head up.
And then he kissed her.
Tsunade tensed at first, her breath catching as the drop of his blood passed between them, dissolving the moment it touched her tongue. But then—fire.
A golden heat exploded within her, surging through every nerve in her body. Her breath hitched as an overwhelming force consumed her. Her bones, muscles, even her very cells were being rewritten.
She gasped, clutching her chest as a golden aura coiled around her, alive, powerful.
"Ryūsei—!"
He held her steady. "Just let it happen," he murmured, watching the transformation unfold.
The Awakening
Tsunade's chakra erupted, colliding and fusing with the power flowing through her veins. The Senju and Uzumaki blood within her reacted violently, their latent potential pulled to the surface. Her body burned, reshaped into something beyond human limits.
And then—her eyes changed.
A searing pain shot through her skull, her vision turning white-hot. When she opened them again—the world was different.
Her irises darkened, shifting into a golden Rinnegan.
Ryūsei inhaled sharply, taking in the sight. "So, that's what awakened…"
Tsunade barely had time to register it before a new power surged forth.
Her hands clenched, and instinctively—she rewound time.
The world flickered. The moment rewound.
She gasped, suddenly standing in the exact position she had been a second earlier, as if nothing had happened. Her mind reeled. She had just undone reality itself.
A New Power Awakens
But before she could fully process it, another shift rippled through her body. A new ability—ancient, instinctive, deadly.
Her fingers twitched. The chakra within her shifted, becoming sharper, denser, lethal.
And then—bones grew from her palm.
Tsunade's breath hitched as a jagged, blackened bone extended from her hand, crackling with eerie energy.
Ryūsei's eyes widened slightly. "Kill Ash Bone…"
Tsunade examined the weapon in her grasp, instincts whispering to her. She understood—if this bone struck someone, it would disintegrate them from the inside out.
Her grip tightened. This was Kaguya's power.
She turned to Ryūsei, eyes burning with realization. "You… you really turned me into a monster like you, huh?"
He chuckled. "A monster? No. A goddess."
Tsunade scoffed, rolling her shoulders. The power… it felt good. Too good.
And then—a new presence entered the room.
Mito's Arrival
Uzumaki Mito stepped into the chamber, her presence alone commanding attention. Her crimson eyes locked onto Tsunade immediately.
Mito froze.
For a long moment, she simply stared—at the golden Rinnegan, at the lethal bone weapon still in Tsunade's grasp.
Then, slowly, she turned her gaze toward Ryūsei.
"…What," she said evenly, "did you do?"
Ryūsei rubbed the back of his head. "I may have… helped Tsunade evolve."
Mito inhaled deeply, clearly controlling her emotions. Then, she exhaled sharply and folded her arms.
"…And what was the price?"
Tsunade's brow furrowed. "Price?"
Mito's gaze didn't waver. "Ryūsei doesn't gain power without consequence. There's always a price. What did you give up this time?"
Ryūsei's expression grew serious. "Genesis—the ability that let me transform Tsunade—it has a cooldown now. I can't use it again for at least a year."
Mito's lips pressed into a thin line. "A year's cooldown… for power like that?" Her eyes flickered with something unreadable. "You got off lightly."
Ryūsei didn't respond.
But Mito wasn't done. She turned back to Tsunade, her gaze piercing.
"And you? How do you feel?"
Tsunade flexed her fingers, testing her body, her chakra. A smirk tugged at her lips. "Like I could crush a mountain with my bare hands."
Mito sighed, rubbing her temples. "I swear, this family is going to drive me insane."
Tsunade grinned. "I could always rewind time and stop that from happening."
Mito gave her a long, tired look. "…I need tea."
Testing the Divine Powers
The air crackled as they moved to an open training ground.
Ryūsei stood across from Tsunade, eyes gleaming. "Let's see what you can do."
Tsunade's Rinnegan flashed.
She lunged at him, faster than even she anticipated. Ryūsei countered—only to be rewound a moment before his counter landed.
He staggered.
She smirked. "Having trouble?"
He grinned. "Not at all."
Ryūsei retaliated, pushing her to test her Kill Ash Bone. She struck at a nearby boulder—it turned to dust instantly.
She stared at her own hand, flexing it. Unbelievable.
She had become something beyond human limits.
And for the first time in her life, she felt truly unstoppable.
A New Era Begins
Tsunade turned back to Ryūsei, her golden Rinnegan shining, the weight of her new power settling in.
She had changed.
No—she had ascended.
And with Ryūsei by her side, the world had no idea what was coming.
