Naruto: The Medical Ninja

Chapter 333: Chapter 330~ Many Kinds of Chakra Control

The Iburi Clan had just received the Yang Anchor Seal—a tool that would change their lives, perhaps save their entire bloodline. Ryu had delivered on his promise. Now came the next part: building the infrastructure to support them, integrating them into the village, and ensuring they thrived rather than merely survived.

After that, they returned back to Leaf Village after visiting the cave of the Iburi Clan.

”Finally... back and one more problem solved... almost solved,” Ryu said as they passed through the Hamura compound gates.

Ryu then looked at Kaori and said, ”Ms Secretary!!”

Kaori stepped forward immediately, falling into her professional role. ”Yes, Boss.”

Ryu stopped, turning to face her. ”Spread the word about the satellites and communication towers. Send envoys to neighbouring nations. Offer them our products and make a presentable portfolio with all the advantages.”

Kaori nodded. ”I’ll dispatch marketing teams immediately.”

”Good.” Ryu paused. ”Frame it as a revolutionary and developmental opportunity... Emphasise economic growth, faster communication for merchants, and better coordination for security forces and rulers too.”

”Understood.” Kaori nodded, then left for the company building to handle her assignments.

Ryu watched her go, then glanced at Kohinata. Close by, the Elite Jonin crossed his arms. Ryu noticed his calm expression—curiosity barely contained.

”Ask away, Mr Kohinata,” Ryu said, heading towards the training ground at the far end of the compound.

Kohinata followed. ”How did you do it?”

Ryu glanced back. ”The Yang Anchor Seal?”

”That seal,” Kohinata confirmed, his voice carrying genuine wonder. ”That chakra—it was the purest form of Yang I’ve ever seen in my entire life.”

A faint smile crossed Ryu’s face. ”You should get used to it, Mr Kohinata. Stick around me long enough, and you’ll see many impossible things.”

They reached the training ground—a wide, open space bordered by trees. Several hummingbirds flitted between the branches, their iridescent feathers catching the afternoon light. Ryu stopped in the centre and turned to face Kohinata.

”You want to know how I did it with fuinjutsu.”

”Yes.”

Ryu shook his head. ”Actually... I didn’t.”

Kohinata blinked. ”What?”

”The fuinjutsu belonged to someone else,” Ryu explained. ”I can’t disclose their identity.... They’re... private. Very private. But they agreed to help the Iburi Clan.”

Kohinata absorbed that, nodding slowly. He was a ninja so he understood the weight of secrets. It was the job description for a ninja to keep secrets.

”What I can tell you,” Ryu continued, ”is how I did it.”

Kohinata’s confusion flickered across his face for half a second. Ryu caught it and almost laughed.

Ryu said, ”You’re wondering why I can explain the method but not the source.”

Kohinata nodded. A new, unique and impossible skill was like a treasure for any ninja. Kohinata knew he was learning stuff most people would kill for.

Ryu clasped his hands behind his back, adopting a lecturing tone. ”Tell me, Mr Kohinata. What comes to mind when I say ’perfect chakra control’?”

Kohinata considered the question. ”It could be many things. The Hyuga think they have perfect chakra control. So do the Senju.”

”Right answer,” Ryu nodded approvingly. ”Everyone thinks they have the best of something once they’ve achieved something good and unique. But the thing is, there are variations of similar concepts.”

He gestured towards the ground. ”Take chakra control, for example.”

Kohinata leaned forward slightly, his attention sharpening.

”The Hyuga excel at precision,” Ryu explained. ”They can release chakra from a chakra point the size of a needle’s tip and hit an enemy’s chakra point precisely at its centre.”

Ryu stepped forward, raising his fist. ”The Senju, on the other hand, specialise in instantaneous bursts of large amounts of chakra. Like this.”

He punched the ground.

The impact created a crater in the earth beneath his fist, with cracks spreading outward in a perfect radial pattern. Dust exploded upward, and the shockwave rippled through the training ground.

Kohinata’s eyes widened.

Ryu straightened, brushing dust from his knuckles. ”Senju-style chakra control. Explosive. Overwhelming. Built for devastating single strikes.”

”And both can be considered perfect chakra control from their viewpoints,” Kohinata replied.

”Exactly,” Ryu turned, meeting his gaze. ”Both are ’perfect’ in their own way, but they’re also fundamentally different.”

Ryu extended his right hand, palm upward. Chakra gathered in his palm—swirling, condensing with controlled rotation into a perfect sphere of pressurised chakra. The rotation was tight and controlled, the sound a high-pitched whine.

”[Rasengan],” Ryu said simply.

The sphere pulsed with raw power, spiralling in place above his hand.

”This technique focuses on perfect shape manipulation,” Ryu continued. ”No elemental nature. No hand seals. Nothing but pure, rotating chakra compressed into a stable form.”

Kohinata stared at the [Rasengan], transfixed. ”The Fourth Hokage’s technique.”

Ryu said, ”Yes but I have one more like this.”

Chakra gathered in his left palm—different from the [Rasengan]. This was darker and denser, with a faint shimmer that made the air around it ripple. A perfect sphere, utterly still, no rotation required.

”Yin chakra,” Ryu explained. ”Different from the Yang you saw earlier in the cave. This is the result of perfect Yin-Yang chakra control.”

Kohinata’s breath caught. Two spheres—one in each hand. Both mesmerising, both impossible. He’d seen S-rank techniques before—but never seen them with this level of control. Not from someone who shouldn’t even be a genin yet.

”Out of all the chakra control methods,” Ryu said quietly, ”this one is the finest and the most versatile. I’m still exploring what I can do with it, but ideas keep coming.”

The training with Kiyomizu was paying off faster than expected. What had taken the Otsutsuki generations to perfect, Ryu was absorbing in a week.

”I can do this too,” Ryu said.

Ryu dissolved the [Rasengan] as he focused on the Yin sphere in his left hand. The sphere elongated, stretching upward and outward, reshaping itself into a golden burning staff.

Ryu swirled it in one hand and shifted into a combat stance. The staff moved fluidly, an extension of his body. He twirled it again, then gripped it with both hands. The staff split cleanly down the middle, forming two batons.

Ryu played with them, spinning both and showing off his dexterity with them.

The shapes changed again—simultaneously. One baton thickened, spikes erupting along its length, transforming into a fanged mace. At the same moment, the other flattened and extended, becoming a battle axe.

”Flashy enough for you, Mr Kohinata?” Ryu asked, a hint of amusement in his voice.

Kohinata found his voice. ”Whoever taught you this must be a beast when it comes to chakra control.”

Ryu replied, ”Yes. They are even better than me. They’ve perfected this over generations.”

Kohinata’s brow furrowed slightly. ”Generations? You mean... a clan technique?”

”In a sense.” Ryu looked at Kohinata carefully. ”You want to learn this? I’m sure they won’t mind if it’s you.”

Kohinata was surprised. ”Why me? Because I’m with you?”

”Yes and no.” Ryu paused. ”It’s more because of your ancestry.”

Kohinata’s confusion deepened. He’d watched the Hyuga for years, hoping to glean insights into their methods. He knew they had no such technique for chakra control—nothing like what Ryu had just demonstrated.

”I’m not following.”

Ryu studied him for a long moment. Then he asked quietly, ”Can you keep a secret, Mr Kohinata?”

Kohinata nodded without hesitation.

”The first person to invent this method,” Ryu said slowly, ”was also the same person who was first born with the Byakugan. Millennia ago. His name was Hamura.”

Kohinata froze.

The words hung in the air like a blade.

Ryu continued, his tone matter-of-fact. ”He’s the progenitor of the Hamura clan—my clan. Also the Hyuga clan and a few more clans scattered across the world.” His eyes met Kohinata’s. ”Through the Hyuga clan, you and I are also related, Mr Kohinata, dating far back to millennia ago.”

Kohinata’s mind reeled. He’d never heard that name before. Not in any village history. Not from any of his Hyuga friends. Not even in whispered legends. The name was completely foreign to him—and yet this child spoke it with absolute certainty, tying it directly to the origin of the Byakugan itself.

The revelation struck like a physical blow.

”Ryu-kun,” Kohinata said carefully, his voice strained, ”how do you know that name that doesn’t exist in any record? And how do you know about... about my ancestry?”

Ryu met his gaze steadily. No surprise registered on his face. He’d been waiting for this question.

”I can’t tell you that, Mr Kohinata.”

Kohinata’s jaw tightened. ”Can’t, or won’t?”

”Both.” Ryu tilted his head. ”But know this—I know more than people realise. About many things. About many people.”

The words carried no threat, no boast. Only truth.

Kohinata searched Ryu’s face, looking for deception or arrogance. He found neither.

Ryu said, breaking the ice, ”I will teach you this method once I master it myself.”

Kohinata glanced at the spot where the chakra constructs had been. ”You seem pretty good with it already.”

”Making sticks made out of chakra isn’t the only thing this method can achieve,” Ryu said. ”You have no idea what more it can do... I will teach you.”

”I’d be grateful.”

Silence settled between them, comfortable now.

Ryu’s expression shifted, turning serious. The lightheartedness from moments before evaporated.

”I’m not teaching you out of goodwill.”

Kohinata raised an eyebrow. ”What, then?”

”I’m preparing for war.”

The words landed like a stone.

”War?” Kohinata repeated.

”A war is coming,” Ryu said, his voice calm but edged with certainty. ”Every enemy that will come after me is Kage-level. Or close to it. So I’ll be needing Kage-level help.”

Kohinata frowned. ”You’re too paranoid, Ryu-kun. No one can dare attack you inside the Leaf.”

”But what about outside?”

Kohinata opened his mouth, then closed it.

”Orochimaru will be next to come after me,” Ryu continued, tone matter-of-fact.

Kohinata stiffened. ”How can you be so sure?”

”Because he’s the go-to person Danzo uses to finish people he can’t deal with himself,” Ryu explained. ”And Lord Hokage has tied Danzo’s hands now. So he’ll turn to Orochimaru. Right now he is founding his own ninja village, but soon afte rthat he will attack me.”

”You’re overthinking—”

”Orochimaru isn’t the only one who’ll be coming after me,” Ryu interrupted. His eyes were distant now, calculating. ”There are people stronger than Orochimaru hidden in the shadows.”

Kohinata studied him. ”I’ve never seen you this paranoid before.”

”I’m not scared,” Ryu said, his voice dropping into something colder. ”But I’m not arrogant enough to avoid preparing. By the time they come for me, I’ll have a contingency for every one of them.”

He turned, locking eyes with Kohinata. ”Everyone has a weakness. And I know the weaknesses of all of them.”

”This kid is dangerous,” Kohinata thought, a chill running down his spine.

The Yin chakra mace in Ryu’s hand morphed into a shield—flat, wide, and perfectly circular. In the battleaxe in his right hand, a long spear took shape, the tip sharp and deadly.

”I’ll be ready for them when the time comes,” Ryu said quietly. ”Their weakness will be my shield.” He raised the spear. ”My plans and my men will be my spear.”

After the declaration and a perfect pose, the constructs dissolved.

Ryu lowered his hands and added, ”Training starts tomorrow at noon.”

Kohinata nodded slowly, thinking, ”Funny, I am an elite jonin yet being trained by gennin. but this is too good to be missed... maybe I can learn more mysteries of this world by being at his side.”

Ryu raised his hand and snapped his fingers and a sharp crack echoed through the training ground.

One of the hummingbirds perched in the nearby tree took flight, zipping through the air in a blur of iridescent green and blue. It landed on Ryu’s extended finger, tiny claws gripping gently.

Ryu leaned closer to the bird, his voice dropping to a murmur. ”Tell Akihiro to see me.”

The hummingbird chirped once—a high, crystalline sound—then launched itself into the air, disappearing over the compound walls in seconds.

Kohinata watched it go, then looked back at Ryu. ”You’ve trained them well.”

”They’re useful,” Ryu said simply. ”Fast, hard to track, and smarter than people think.”

Kohinata said nothing. There was nothing to say.

The boy standing before him wasn’t a child. Not really. He was a strategist, a thinker, someone who saw ten steps ahead and planned for every possible outcome.

And somehow, that was more terrifying than any jutsu Ryu could ever demonstrate.

A/N:

Sorry for my absence. I was not in good health. I am still not at my best.

What was Ryu’s reason for saying what he revealed in the Chapter? - He sowed seeds of trust and mystery in Kohinata. Ryu wants Kohinata to know that he is masterminding a plan and Kohinata is part of it.
