Chapter 17: Knock
The third stage of the Rasengan was the problem.
Naruto understood the first two now — understood them in his body, not just his head. The rotation was clean from both hands. The power was stable, the chakra output consistent. He could hold both simultaneously for over a minute without the form destabilizing.
But containment — holding the rotating surging sphere together without an external container, just chakra pressure holding chakra pressure in a perfect self-sustaining form — kept collapsing. Every time he got close he could feel the edges wanting to fly apart, the rotation fighting the containment, the power fighting the rotation.
He was working the problem with twelve clones in the field outside Tanzaku Town when one of them stopped, looked at its palm, and said: "What if the containment isn't a layer around the outside? What if it's built into the rotation itself?"
Naruto looked up.
The clone dispersed before he could ask what it meant — but the memory arrived immediately. The full thought, half-formed but pointing somewhere useful. Not a shell holding the rotation in. The rotation itself being the containment — the spin generating the inward pressure that kept the whole form together.
He tried it.
The sphere formed.
Not perfectly. It lasted four seconds before collapsing. But it was the first time it had formed at all — a genuine rotating compressed sphere of chakra sitting in his palm, blue and humming, for four seconds before the form gave way.
He stood very still for a moment.
Then he grinned.
"That's it," he said to nobody in particular. The remaining clones all turned to look at him simultaneously. "That's the principle. I just need—"
"You need to do it without the clone," said Jiraiya from behind him.
Naruto turned. Jiraiya was leaning against a fence post at the field's edge with his arms folded, watching.
"How long have you been there?"
"Long enough." He pushed off the post and walked over. "Show me again."
Naruto tried again. The sphere formed — three seconds this time before collapsing.
Jiraiya watched it. "The clone figured out the containment principle," he said.
"Yes."
"Now you need to do it single-handed. Without the clone stabilizing the secondary pressure." He looked at Naruto steadily. "That's the last step. One hand. Full form. Stable."
"I know," Naruto said. He looked at his palm. "I'll get it."
"I know you will." Jiraiya turned toward the town. "Clean up and come find me. We need to book a room before the good ones are gone." He paused. "And there's a lead on Tsunade. Someone at the card house on the main street lost significantly last night to a woman matching her description."
"The Legendary Sucker strikes again," Naruto said.
"Consistently," Jiraiya said, already walking.
Tanzaku Town was bigger than the last two stops — a proper market town with wide streets and a substantial entertainment district. Gambling halls lined the central avenue, their signs bright even in the afternoon light. The smell of food and sake and money changing hands drifted through the air.
They found the inn without difficulty — a clean place, mid-range, the kind that didn't ask questions and provided breakfast.
They were halfway through booking the room when a woman appeared at Jiraiya's elbow.
Naruto noticed her immediately and noticed something else at the same time — something off. He couldn't name it precisely. It wasn't her appearance. It was something underneath her expression — a flatness behind the eyes that his instincts caught before his mind caught up. Like the difference between a real fire and a painting of one. The warmth was there on the surface. Something behind it wasn't.
But Jiraiya had noticed nothing of the sort.
The woman said something close to his ear. Jiraiya's expression shifted in a very specific and entirely predictable direction.
"Ah," Jiraiya said. He was already turning. "Research calls." He held up one finger in Naruto's direction without looking at him. "Book the room. I'll be—"
"Jiraiya," Naruto said.
"Yes?"
"Something's off about—"
"I'll be back in an hour," Jiraiya said. He was already moving, the woman's hand on his arm, heading toward the inn's side corridor.
Naruto watched him go.
He stood at the booking desk for a long moment, looking at the corridor where Jiraiya had disappeared. The feeling that something was wrong sat in his gut like a stone. He turned it over, examined it, couldn't find anything concrete enough to act on.
He turned back to the desk, paid for two rooms, took the keys, and went upstairs.
His room was small and clean — a futon, a window overlooking the side street below, a low table. He dropped his pack, sat on the futon, and went back to work on the Rasengan.
Single-handed containment. The principle was clear now. The execution was the problem.
He ran it forty times with shadow clones in the limited space of the room — each attempt feeding information back, each failure pointing to something slightly different to adjust. The sphere kept collapsing. Lasting longer each time but collapsing.
He was on the forty-first attempt when someone knocked on the door.
Three knocks. Unhurried. Deliberate.
Naruto dispelled the clones and stood. "One second."
He crossed to the door.
His hand touched the handle.
His instincts fired before he turned it — a wave of something that wasn't sound or sight or smell but the particular alarm his body had developed over weeks of hunting and being hunted in a forest where everything that wanted to kill him had announced itself through exactly this feeling. The feeling of standing at the edge of something's range that could end him if it chose to.
He turned the handle anyway.
The two figures in the doorway hit him like a physical force — not through action, not through anything visible. Just through what they were. Their chakra signatures were like standing next to a fire that had been burning for a very long time — vast, settled, carrying the particular weight of power that had been integrated rather than accumulated.
The nearer one was lean and dark-haired with pale skin and eyes that were red and spinning. The Sharingan — he'd seen that in Sasuke, knew the basic shape of it. But this was different. Three tomoe in each eye, reading him with a systematic thoroughness that felt like being disassembled and catalogued simultaneously.
Behind him stood something massive. Blue-grey skin. A sword wrapped in bandages on his back — and the bandages moved. Slightly. As if something inside the wrapping was breathing.
Naruto's entire nervous system was saying one thing: these are the most dangerous people you have ever been in a room with.
"Naruto Uzumaki," the nearer one said. His voice was quiet. Completely without urgency. "We'd like you to come with us."
Naruto looked at him for exactly one second.
Then he slammed chakra into his feet and launched himself backward through the room — off the futon, through the window, out into the air above the side street.
He landed on the wall of the building opposite, chakra-sticking to the surface, crouched low, and looked back at the window.
The dark-haired one stepped through it without hurrying. The massive one followed, the bandaged sword already unwrapped and resting on his shoulder. Up close in the open air the chakra signatures were even clearer — enormous, layered, completely controlled. The dark-haired one's red eyes tracked Naruto with the same systematic reading.
"Running," the massive one said pleasantly, "won't help."
"Neither will standing still," Naruto said.
His hands moved. "Shadow Clone Jutsu."
Twenty clones erupted across the side street — wall surfaces, ground level, rooftops. They spread into the hunting formation immediately, low and unpredictable, covering every approach angle.
The massive one looked at them with the expression of someone presented with a mildly interesting puzzle. "Twenty clones. How much chakra does this kid have?"
"Significant reserves," the dark-haired one said. He hadn't moved from the window ledge. His red eyes were tracking all twenty clones simultaneously — Naruto could feel it, the specific quality of that gaze moving across each one, sorting and cataloguing with machine-like efficiency.
He pointed directly at Naruto's position on the wall without looking away from the clones. "That one."
The massive one moved.
Fast — the enormous frame covering distance with an efficiency that didn't match its size. He went directly for Naruto, ignoring the clones entirely.
Naruto launched off the wall — chakra constructs shooting from both hands, eight lines of pure energy aimed at arms and legs simultaneously. The technique that had pinned Sasuke. The technique that had torn through the Toad Mouth Trap.
The massive one let two hit.
The bandaged sword's scales drank the chakra on contact. Not storing it — consuming it. The constructs dissolved against the sword's surface like water on hot stone.
Naruto registered this immediately. Adjusted. He let the remaining constructs go and switched — six clones converging from different angles, abandoning chakra constructs entirely in favor of direct physical contact.
The massive one swung the sword in a wide arc. Three clones burst from the displacement. Two more he caught with his free hand and flung into the wall hard enough to burst on impact. The sixth got close enough to land a kick to his ribs.
He barely moved.
"Good instincts," the massive one said, settling his stance. "Bad matchup."
Naruto's mind was already working — if the sword absorbed chakra constructs on contact then direct chakra techniques were limited. Taijutsu was the angle. Physical pressure, unpredictable movement, First Fang to add weight to the strikes—
He drove forward again. Low arc, close to the ground, the hunting movement with no wasted vertical motion. He got under the sword's range and drove his knee upward into the massive one's midsection — First Fang bleeding into his legs without full activation, just enough to put real force behind it.
It landed.
The massive one rocked back half a step. He looked down at Naruto with an expression that had shifted from amused to something more attentive.
"Hm," he said. "That one I felt."
He grabbed Naruto by the collar and threw him across the street.
Naruto tucked, hit the wall, pushed off. Four clones flanking. He drove forward again — pure taijutsu pressure, striking for the spaces the sword couldn't cover quickly, reading the defense and looking for the gaps.
The massive one defended with the sword's flat and his free arm — actually blocking now rather than absorbing, which meant the direct contact was getting through even without constructs. Naruto's hands were bleeding from where the scales had caught him on the redirects. He didn't stop.
Three clones burst. Two more. He kept making them — chakra cost was real but his reserves ran deep.
The last clone took the sword's handle across the jaw and burst. Naruto himself took a flat-handed strike to the chest that lifted him off the ground and sent him sliding across the cobblestones.
He stopped. Got up.
Breathing hard. Hands bleeding. Eyes still sharp.
The massive one looked at him from across the street. The expression was no longer amused — something more genuine had replaced it. The look of someone who had been testing and had found the result more interesting than expected.
"Kid," he said, "you're going to be a serious problem for someone someday."
"Starting with you," Naruto said.
"No," the massive one said pleasantly. "Not me. Not today."
He rolled his shoulders and brought the sword up.
Naruto's instincts spiked. The shift from playing to serious was specific and immediate — a change in the quality of the massive one's stance, the way his grip on the sword changed, the particular focus arriving in his eyes.
He started cycling through what he had left. How much chakra. Which approaches hadn't been mapped by those red eyes yet. Whether First Fang full activation was the right call or whether the cost was too high given he didn't know how long this would last—
A sound.
The howl of lightning chakra — specific, screaming, the pitch Naruto knew from three weeks ago in Training Ground Seven.
Chidori.
Sasuke came off the rooftop above the side street with his arm blazing white-blue, dropping toward the dark-haired one with the full committed weight of someone who had been running for a very long time and had arrived with everything they had.
The dark-haired one turned.
One hand moved — not toward the blazing arm but to the side of it, catching Sasuke's elbow in a precise grip that locked the joint and killed the momentum of the entire strike in a single controlled motion. The Chidori screamed and crackled against the air an inch from his chest — close enough that the lightning chakra lit his face blue-white — and didn't move forward another centimeter.
The side street went very quiet.
Sasuke strained against the hold — every muscle, every reserve, years of hatred and training compressed into this single point of contact — and the arm didn't move. The locked elbow joint turned the full force of the Chidori into something that couldn't go anywhere, couldn't be released, just crackled uselessly in the space between them.
The dark-haired one looked at Sasuke. His expression was the same as it had been since he appeared at the door — flat, unreadable, carrying something behind it that Naruto couldn't read from across the street.
"You came a long way," the dark-haired one said. Quiet. Almost gentle.
"Let go," Sasuke said through clenched teeth. "Let go—"
The dark-haired one released the elbow and stepped back. The Chidori sputtered and died without the pressure of momentum to sustain it. Sasuke landed on the cobblestones, arm still extended, breathing hard from the run and the technique combined.
He straightened. His Sharingan was burning — reading the dark-haired one with the specific focus of something deeply personal.
"I've been waiting," Sasuke said. His voice cracked slightly at the edges. "My whole life I've been waiting—"
"I know," the dark-haired one said.
"Don't act like you understand—"
"I don't need to understand it," the dark-haired one said. "I caused it."
Something broke loose in Sasuke's expression. The controlled surface — the calculated coldness he'd been building for years as armor against exactly this moment — fractured.
He rushed the dark-haired one.
Not with a technique — just himself, fists and speed and the Body Flicker carrying him forward, the Sharingan trying to read responses fast enough to land something, anything—
The dark-haired one was better. By a magnitude that was specific and deliberate. Every strike Sasuke threw was read before it arrived — deflected, redirected, avoided with minimum movement. No counterattacks. Just Sasuke missing, missing again, his combinations getting ragged from frustration.
Then the dark-haired one hit him.
A single open palm to the chest that stopped Sasuke's momentum completely. A sweep of the leg that took him off his feet. A controlled placement onto the cobblestones that was less a throw and more a deliberate positioning.
Sasuke got up immediately.
"You're not ready," the dark-haired one said.
"I don't care—"
Sasuke charged again.
The red eyes shifted. The tomoe accelerated. Something deeper activated behind them — the pattern changing in a way that Naruto's instincts screamed at without being able to name. A wrongness in the air. A door opening somewhere that had no right to open.
"Sasuke—"
Tsukuyomi.
Sasuke stopped mid-charge.
Stood completely still for three seconds.
Then his legs gave out and he went down — not dramatically, not with a sound. Just down, the way something goes when what was holding it up has been removed. He hit the cobblestones and didn't move.
Naruto was beside him instantly — crouching, hand on his shoulder, reading the damage. Something was wrong in a way he couldn't name. The fractured quality to Sasuke's stillness. The specific pattern of something that had left the body intact and taken everything else apart.
He looked up at the dark-haired one.
The red eyes were looking back at him. Still reading. Still systematic.
"He'll recover," the dark-haired one said. "It takes time."
He turned back to Naruto.
And something shifted.
The quality of his attention changed — the assessment was finished, the cataloguing complete. What was looking at Naruto now wasn't reading anymore.
It had decided.
"You understand what we want," the dark-haired one said. Not a question.
Naruto said nothing. His instincts were screaming.
"There is a creature sealed inside you," the dark-haired one continued. His voice was the same — quiet, unhurried, completely without cruelty. As if he were explaining something factual to someone who deserved to understand the situation they were in. "The Nine-Tailed Fox. We are going to take it." He paused. "We would prefer you cooperate. It will be less painful that way."
Naruto stared at him.
"You came all this way," Naruto said. His voice was steady. "For the Nine-Tails."
"Yes."
"Then you can go home empty handed."
The dark-haired one regarded him for a moment. Then he glanced at the massive one.
The massive one moved.
Not with the playful energy of before — not testing, not toying. This was different. The enormous frame crossed the distance with the focused efficiency of someone executing a task, Samehada angled to absorb rather than cut, positioned to drain rather than destroy.
Naruto's instincts fired everything simultaneously.
He launched — not toward the massive one, sideways, trying to create distance and angle. Ten clones erupted around him, the hunting formation, buying fractions of seconds. He drove chakra into his legs, First Fang bleeding in—
The massive one was faster. He batted three clones aside with Samehada's flat in a single sweep and closed the remaining distance. His free hand caught Naruto's wrist — the grip was absolute, the kind that didn't allow for technique or leverage because the raw difference in strength made both irrelevant.
Naruto pulled. Twisted. Drove a heel into the massive one's shin.
He didn't move.
"Done," the massive one said. Not unkindly. "Good fight, kid. Seriously."
Naruto looked at the grip on his wrist. Looked at Samehada's scales turning slowly toward his arm. Looked at the dark-haired one crossing the street toward him with the same unhurried patience he'd had since the door.
He looked for an exit. There wasn't one.
He thought about the gate. About the Second Fang. About what it would cost and whether it would even matter against these two—
Something landed in the space between Naruto and the dark-haired one.
Not a toad. Not a technique. Just a person — dropping from somewhere above, landing between them in a single instant, straightening from the crouch of the landing into a stance that filled the narrow street with a presence Naruto recognized immediately.
Jiraiya.
Not the version that chased women and quoted research obligations and laughed too loudly. Not the version that leaned against fence posts watching training sessions with mild interest.
The theatrical energy was completely gone. Every layer that wasn't necessary for what was about to happen had been stripped away in the space of a landing. What stood between Naruto and the dark-haired one was something old and vast and not interested in anything except the two people on the other side of it.
The massive one's grip on Naruto's wrist didn't release immediately. He looked at Jiraiya with the careful assessment of someone recalculating everything he'd planned for the next sixty seconds.
The dark-haired one had stopped.
The red eyes read Jiraiya the way they had read everything else tonight — systematic, thorough, arriving at a conclusion with the same unhurried efficiency.
The two of them looked at each other across the narrow side street of Tanzaku Town.
No words yet.
