Six months of relentless medical study had transformed Dan Senjumaki's understanding of the human body and chakra alike.
Where once chakra coils had seemed immutable—either intact or broken—Dan now saw them as something closer to a living construct, a fusion of physical form and spiritual intent. With each passing week, his confidence grew. He was certain now that he could re-create and restore the damaged chakra coils of the comatose Kushina Uzumaki.
The breakthrough had come with his mastery of perfect Yin–Yang Release: the Creation of All Things.
Unlike conventional medical ninjutsu, which merely stimulated natural healing, Yin–Yang allowed Dan to bridge imagination and reality. Yin gave form to thought, while Yang breathed life into that form. In its purest expression, it was the same divine principle used by the Sage of Six Paths himself—creation born from will alone.
Yet such power came at a cost.
Creating something from absolute nothing placed an immense burden on the body, mind, and soul. Even Dan, with his abnormal reserves and lineage, could not sustain such feats lightly. However, Kushina's condition offered a crucial distinction. Her chakra coils were damaged, not erased. They existed—fractured, distorted, incomplete—but still present.
Restoring what already existed was far easier than forging something anew.
Using Yin–Yang Release to reinforce, reshape, and repair those damaged pathways was, comparatively speaking, an easy fix.
Still, Dan did not intend to act alone.
To demonstrate the true philosophy of Ninshu—not domination, but cooperation—he sought the assistance of the Nara and Akimichi clans. These two clans possessed an exceptional balance of Yin-based chakra and physical vitality, making them ideal collaborators for stabilizing the process. Their involvement was not strictly necessary, but it embodied the very principle Dan wished to revive: chakra as a bond between people, not merely a weapon.
This was not just a medical procedure.
It was a declaration—of knowledge, of unity, and of how far Ninshu had evolved under his hands.
The Clans
The first visit was to the Nara clan.
Shikaku Nara listened in silence as Dan explained the theory—how Yin chakra could stabilize the damaged spiritual pathways, how mental discipline and shadow-based chakra control could help anchor the reconstruction. When Dan finished, Shikaku's eyes were sharp with calculation rather than disbelief.
"You're not asking for strength," Shikaku said slowly. "You're asking for precision."
Dan nodded. "And clarity. This technique responds better when the mind is steady."
A long pause followed.
"…You'll have my people," Shikaku finally said. "On one condition. We observe everything."
"That was always the intent," Dan replied.
The Akimichi clan required less explanation, but no less respect.
Their immense vitality, body-expansion techniques, and mastery of Yang chakra made them the perfect counterpart to the Nara's Yin. Where the Nara would shape and stabilize, the Akimichi would reinforce and nourish.
Chōza Akimichi frowned deeply as he listened, arms folded.
"You're talking about rebuilding something that even the best med-nin couldn't touch," he said. "If this goes wrong—"
"It won't," Dan said calmly. "But if it does, the backlash will fall on me. Not your clan."
Chōza studied the boy for a long moment before exhaling.
"…You sound like a Senju," he muttered. "Fine. We'll help."
With the clans in agreement, only one obstacle remained.
The Hokage's Demand
The Third Hokage did not approve immediately.
In fact, he didn't approve at all.
"This technique you're proposing," Sarutobi Hiruzen said, smoke curling from his pipe, "is dangerously close to forbidden territory."
Dan stood straight in the Hokage's office, hands folded behind his back.
"It predates the concept of forbidden techniques," Dan replied. "It is Ninshu."
The Hokage's eyes narrowed slightly. "Words won't be enough."
"I expected as much."
Sarutobi exhaled slowly. "If you want my authorization—if you want clan involvement in something this unprecedented—you will demonstrate."
He turned toward the door. "Bring him in."
Two ANBU appeared moments later, escorting a man whose presence alone told a grim story. One leg dragged uselessly behind him. His chakra signature was faint, uneven—like a flickering candle.
"A former ANBU operative," Sarutobi said quietly. "His chakra coils were shattered during a classified mission. He hasn't molded chakra in eight years."
The man said nothing. He didn't need to.
Dan stepped closer, eyes soft but focused.
"May I?" he asked.
Sarutobi nodded.
The Demonstration
Dan knelt, placing two fingers lightly over the man's abdomen.
He closed his eyes.
Yin chakra flowed first—subtle, invisible, forming a perfect mental blueprint of what should exist. Damaged pathways were mapped, fractures outlined, distortions corrected in thought alone.
Then Yang followed.
Warm. Steady. Alive.
The chakra did not surge or explode. It settled, knitting torn coils together like careful hands weaving silk. The room grew heavy—not with pressure, but with presence. Even the Hokage felt it.
Creation without force.
Life without violence.
The man gasped.
Chakra flared—clean, stable, whole.
He stood.
Slowly. Unsteadily.
Then dropped to his knees, laughing and crying at once as chakra flowed through him for the first time in nearly a decade.
Silence gripped the office.
Sarutobi stared.
"…How many could you heal this way?" the Hokage asked at last.
Dan opened his eyes, fatigue finally showing.
"A few," he answered honestly. "Before rest is required. Kushina Uzumaki would take less than this."
The pipe slipped slightly in Sarutobi's fingers.
After a long moment, the Hokage straightened.
"You will have authorization," he said. "The clans will assist. And this technique—"
"—will be documented," Dan finished. "And safeguarded."
Sarutobi nodded once.
"For the sake of the village… proceed."
And for the first time since the Nine-Tails attack, hope quietly returned to Konoha.
The Healing – With the Clans and the Child
The chamber beneath the hospital had been sealed and reinforced, its walls etched with suppression seals and sensory dampeners. At its center lay Kushina Uzumaki, her red hair spread like a fading flame against the white sheets, her breathing shallow but steady.
Around her, members of the Nara and Akimichi clans took their positions, forming a careful ring. Shadow-users sat cross-legged, eyes closed in deep mental focus, while the Akimichi knelt nearer, palms resting against the floor as Yang chakra rolled from them in slow, measured waves.
Dan Senjumaki stood at the head of the formation.
Before he could begin, he turned toward the Third Hokage.
"There is one more condition," Dan said calmly.
Sarutobi raised an eyebrow. "You've already been granted extraordinary latitude."
"I know," Dan replied. "This one is necessary."
The room stilled.
"I want Naruto Uzumaki present."
The reaction was immediate.
"That's impossible," one of the ANBU snapped.
"He's a jinchūriki," another said. "This is a high-risk procedure—"
"He is her son," Dan interrupted, voice firm but not raised.
Silence fell.
Sarutobi studied him closely. "Explain."
Dan's Reasoning
"This technique is not ordinary medical ninjutsu," Dan said. "Yin–Yang Release responds to intent, bonds, and continuity. Kushina's chakra is fractured, but it is still hers. Naruto carries her chakra signature—faint, undeveloped, but present."
The Nara sensed it immediately. Several of them frowned in thought.
"He acts as an anchor," Dan continued. "A living reference point. Not as a chakra source—he will not be touched—but as a resonance. Mother to child."
Chōza Akimichi's eyes widened slightly. "You're saying her chakra will recognize him."
"Yes."
Sarutobi exhaled slowly. "…And the risk?"
Dan did not hesitate. "There is less risk with him present than without."
A long silence followed.
Finally, the Hokage nodded. "Bring him."
Naruto's Arrival
Naruto was small.
Too small for the weight of the room, for the seals on the walls, for the chakra pressing softly against his skin. He clutched a blanket around his shoulders, wide blue eyes darting from masked ANBU to unfamiliar clan shinobi.
Then he saw her.
"…Mama?" he whispered.
The word alone made several Akimichi look away.
Dan knelt beside him.
"You don't have to do anything," Dan said gently. "Just stay here. And hold my hand if you want."
Naruto nodded, gripping Dan's fingers with surprising strength.
The Clans Act
"Begin," Dan said.
The Nara clan moved first.
Shadows stretched—not physically, but spiritually—linking minds together into a single, steady network. Yin chakra flowed in precise, silent patterns, forming the conceptual framework of Kushina's chakra coils as they should be.
Not forcing.
Not replacing.
Remembering.
The Akimichi followed.
Yang chakra pulsed like a heartbeat, warm and nurturing, flooding the framework with vitality. Where the coils had been thin and frayed, they thickened. Where they had twisted, they straightened.
At the center of it all, Dan placed his hands over Kushina's seal.
Yin shaped the idea.
Yang gave it life.
Creation—not from nothing—but from love, memory, and continuity.
Naruto whimpered softly as Kushina's chakra stirred.
Her fingers twitched.
Her chakra reached—instinctively, desperately—toward the familiar presence beside her.
Mother to child.
The coils locked.
The Result
Kushina's breathing evened.
Her chakra stabilized.
For the first time since the Nine-Tails attack, her seal no longer screamed in pain.
Dan finally withdrew, exhaustion washing over him as the clans slowly disengaged, one by one.
Naruto felt warmth.
"…She's warm," he murmured.
Sarutobi closed his eyes.
Ninshu had returned to Konoha—not as legend, but as practice.
And at its center stood a child, a mother, and a boy who understood that power meant nothing without bonds.
Kushina Uzumaki Awakens
For a moment, nothing happened.
Then Kushina Uzumaki inhaled sharply.
Her chakra surged—sudden, vast, and untamed—rippling outward like a tidal wave finally breaking free of confinement. The seals along the chamber walls flared as her body, long dormant, struggled to reconcile restored chakra coils with muscles and organs that had known only stillness.
Her fingers clenched.
Her heartbeat spiked.
"That's too much," one of the Akimichi muttered. "Her body—"
Dan was already moving.
"Senzu," he said sharply.
In a single fluid motion, he produced the small green bean and crushed it between his fingers, chakra flowing through it to soften its release. He pressed it gently to Kushina's lips.
"Swallow," he commanded—not as an order, but as a direction her body understood.
The senzu dissolved instantly.
Balance
The effect was immediate—and profound.
Yang energy surged first, flooding weakened muscles, knitting tissue that had atrophied over months of stillness. Blood flow normalized. Breath deepened. The body remembered how to live.
Then Yin followed.
Not mindless vitality, but structure—restoring neural pathways, stabilizing consciousness, anchoring memory and identity back into flesh. Where raw power threatened overload, Yin imposed harmony.
Life did not merely return.
It settled.
Kushina's chakra flared once more—then calmed, flowing smoothly through fully restored coils, powerful yet controlled.
Dan exhaled slowly, shoulders sagging as the crisis passed.
"That… was necessary," he said quietly to the stunned observers. "Creation restores structure. The senzu restores balance."
The First Words
Kushina's eyelids fluttered.
Slowly, painfully, they opened.
Light spilled in—and with it, confusion, sensation, presence. She gasped softly, hands curling into the sheets as her body responded fully, completely, without pain.
"I—" Her voice was hoarse. "I can… feel everything."
Naruto froze.
Then he leaned forward, eyes wide, trembling.
"Mama…?"
Her gaze snapped to him.
Time stopped.
Blue eyes—Minato's eyes—stared back at her from a tiny face framed in blond hair. Kushina's breath caught as something deep and instinctive resonated between them, chakra singing in recognition.
"…Naruto?" she whispered.
The boy let out a choked sob and scrambled forward, clutching her hand.
"You're awake!" he cried. "You're really awake!"
Kushina laughed weakly, tears streaming freely as she squeezed his fingers with real strength.
"I'm here," she said. "I'm really here."
Aftermath
Around them, seasoned shinobi stood in stunned silence.
A woman who should never have woken up was sitting up, alive, whole, her chakra stronger and cleaner than it had been even before the Nine-Tails attack.
Dan stepped back, exhausted but composed.
"Ninshu restores what was lost," he said softly. "But life must be lived to stay balanced."
Sarutobi closed his eyes.
This was no longer medicine.
It was resurrection—without sacrilege.
And the future of Konoha had just changed forever.
Kushina Uzumaki did not need long to realize something was wrong.
Not wrong in the sense of pain or weakness—quite the opposite. Her body felt too whole. Chakra flowed through her coils smoothly, powerfully, without the faint resistance she had lived with even before the Nine-Tails attack. Every breath came easy. Every heartbeat was strong.
She flexed her fingers slowly, eyes never leaving Dan Senjumaki.
"You," she said hoarsely.
Dan looked up, meeting her gaze without flinching.
"That wasn't standard medical ninjutsu," Kushina continued. "Not Senju healing. Not Uzumaki vitality tricks." Her eyes narrowed, sharp even through exhaustion. "That felt like… creation."
The room went still.
Dan inclined his head slightly. "Yin–Yang Release. In its original form."
A sharp breath escaped her lips.
"That's impossible," she said immediately. "The only one who—"
She stopped herself.
The name Hagoromo did not need to be spoken.
Kushina stared at him, then laughed weakly, shaking her head.
"…Minato always said the world was changing," she murmured. "Guess he undersold it."
The room softened at the mention of her husband. The absence was heavy, unspoken, but absolute.
Dan said nothing. He didn't need to explain himself further.
Naruto chose that moment to launch himself forward.
"MAMA!"
He wrapped his arms around her waist with everything he had.
Kushina barely had time to gasp before she was nearly knocked backward by the force of him. Instinctively, she caught him—really caught him—arms locking around his small body.
He was warm. Solid. Alive.
She froze.
Then she crushed him against her chest.
"Oh—oh no you don't—" she laughed through tears, voice breaking as she hugged him harder, tighter, as if daring the world to take him from her again. "You're not going anywhere. Not ever."
"M-Mama—!" Naruto squeaked, his feet lifting off the floor. "Too tight! Too tight!"
"That means it's working," Kushina said fiercely, burying her face in his hair. "I missed you. I missed everything."
Naruto clung to her, laughing and crying at the same time.
Around them, hardened shinobi quietly turned away.
Dan watched in silence, exhaustion pulling at him—but there was satisfaction there too. This was what Ninshu was for.
Elsewhere — ROOT Headquarters
The report was delivered in a sealed room, by a man who did not meet Danzō Shimura's eyes.
"Uzumaki Kushina has awakened," the operative said. "Fully healed. Chakra coils restored. Seal stabilized."
Danzō's cane tightened in his grip.
"…Explain."
"The procedure was led by Dan Senjumaki," the man continued carefully. "Assisted by the Nara and Akimichi clans. Naruto Uzumaki was present."
The room went cold.
"Present," Danzō repeated.
"Yes, sir."
A long silence followed.
Yin–Yang Release. Clan cooperation. The jinchūriki acting as a stabilizing anchor. A comatose Uzumaki restored completely.
Too many lines crossed at once.
"…And the cost?" Danzō asked.
"Minimal. The subject consumed a senzu post-procedure. Recovery was immediate."
Danzō closed his remaining eye.
Creation without sacrifice.
Power without loss.
That was the most dangerous kind.
"Dan Senjumaki," he said quietly, tasting the name. "Is no longer a variable."
He turned toward the darkness.
"He is a threat to the old order."
And for the first time in years, Danzō Shimura felt something uncomfortably close to fear.
Back in the hospital chamber, Kushina finally released Naruto just enough to look him over from head to toe, hands on his shoulders, eyes fierce and wet.
"I'm back," she promised him. "Your dad's not… but I am."
Naruto nodded, wiping his face with his sleeve.
Dan shifted slightly, preparing to withdraw.
Kushina noticed.
"Hey," she said. "Don't think you're slipping away."
She looked at him fully now—really looked.
"You didn't just save my life," she said. "You rewrote what I thought was possible."
Dan met her gaze evenly. "Then use that life well."
Kushina smiled—sharp, proud, unmistakably Uzumaki.
"Oh, I plan to."
And somewhere deep beneath Konoha, the future realigned itself around that single, impossible truth:
Uzumaki Kushina lived.
