The twelve hand seals of ninjutsu—Rat, Ox, Tiger, Hare, Dragon, Snake, Horse, Ram, Monkey, Bird, Dog, Boar—flowed from Carl's fingers with mechanical precision.
Chiriku watched in silence, his expression unreadable.
"You truly have a gift for this," he said finally. "Chakra extraction in a single night was impressive. But memorizing all twelve seals after a single demonstration, executing them flawlessly... that is something else entirely."
Carl lowered his hands. "I've trained my body for a long time, Shishō. Muscle memory comes easily."
It wasn't a lie. Decades of martial arts practice—controlling every fiber, every joint, every microscopic movement—had turned his body into an instrument of precision. The hand seals were just another set of movements to master.
But Chiriku's eyes had changed. Where before there had been polite skepticism—a prince playing at being a ninja—now there was something sharper. Reassessment. Genuine interest.
"Very well," Chiriku said, his tone shifting to something more businesslike. "Since you've mastered the seals so quickly, we'll proceed to actual ninjutsu. The first technique you'll learn is Henge no Jutsu—the Transformation Technique."
He demonstrated the single seal required, then explained the chakra flow: how to gather energy, how to circulate it through the proper meridians, how to project it outward to create the illusion of a different form.
Carl listened carefully, then formed the seal himself.
He focused inward, drawing on the sennin chakra he'd refined. The golden energy responded, flowing through pathways he was only beginning to understand—
His form blurred. For a fraction of a second, he felt himself shifting, becoming something else—
Then the technique collapsed, and he was himself again.
"Not yet," Carl said calmly.
Chiriku's expression flickered with something that might have been relief.
"That's perfectly normal," he said, and Carl could hear the subtle reassurance in his voice. "Ninjutsu requires extensive practice. Most students take weeks or months to successfully perform their first technique. The failure rate for beginners is—"
"I understand, Shishō."
Carl wasn't disappointed. He'd known this would happen.
Hand seals and chakra extraction leveraged his existing strengths—physical control, willpower, body awareness. But actually using chakra to create external effects? That was an entirely new skill. No amount of martial arts training had prepared him to manipulate energy outside his own body.
In this regard, he was no different from any other beginner.
But I have advantages they don't, he reminded himself. Patience. Discipline. And three months of uninterrupted time to practice.
"I'll work on it tonight," he said. "Please continue explaining the theory."

*One month later.*
"Henge!"
Carl's hands blurred through the seal. Chakra surged through his body, and his form rippled—
Where he had stood, Chiriku now appeared. Same height. Same robes. Same shaved head and flame tattoo. The transformation was perfect down to the smallest detail.
Carl held the technique for three seconds, then released it.
"Bunshin!"
Another seal. Another surge of chakra.
A second Carl materialized beside him—identical in every way, moving with the same subtle breathing rhythm, the same weight distribution. A perfect illusory clone.
"Kawarimi!"
The third technique. Carl's body dissolved into smoke, and when the air cleared, he was standing five meters away. A block of wood occupied his former position.
The Three Basic Techniques of the ninja academy—Transformation, Clone, and Substitution—executed in rapid succession.
Chiriku nodded slowly. "Excellent. One month to master all three body techniques... you've exceeded my expectations."
Carl allowed himself a small moment of satisfaction.
It had been a difficult month. Unlike chakra extraction and hand seals, ninjutsu didn't come naturally. Every technique required hundreds of repetitions, thousands of small adjustments, endless trial and error as he learned to shape chakra into specific effects.
But he'd done it.
And more than that—he'd felt something he hadn't experienced in years.
The wonder of genuine progress.
In his previous life, he'd eventually hit a ceiling. No matter how hard he trained, his body had limits. He could dodge bullets through prediction, but he couldn't outrun a machine gun. He could break bones with his strikes, but he couldn't punch through armor plating.
At some point, he'd accepted those limits. Focused on making money instead, building security through wealth rather than strength.
But here, in this world, the limits were different.
Transformation. Becoming another person entirely, wearing their face like a mask.
Clone. Creating a duplicate of himself from nothing but shaped chakra.
Substitution. Teleporting across space in an instant, leaving a decoy behind.
These were impossible by the physics of his original world. But here, with chakra, they were just techniques. Skills that could be learned, practiced, mastered.
And these were only the basics.
If the fundamentals are this remarkable, Carl thought, what are the advanced techniques like?
He remembered fragments from the manga—ninjas breathing fire, walking on water, summoning creatures from other dimensions. He'd thought those were exaggerations, artistic license.
Now he wasn't so sure.
"Chuan." Chiriku's voice pulled him from his thoughts. "You've proven yourself with the basics. It's time to begin the next phase of your training."
"Yes, Shishō?"
"Combat."
---
The Temple of Fire's training grounds were alive with activity when they arrived.
Dozens of monks practiced in the morning sun—running through taijutsu forms, sparring in pairs, performing conditioning exercises that would have broken normal humans. Their movements were faster than they should have been, stronger than muscle alone could explain.
Sennin chakra enhancement, Carl observed. The passive strengthening Chiriku mentioned. These monks have been building their bodies for years.
"Chuan," Chiriku said, "as a ninja, ninjutsu and taijutsu are merely tools. The ultimate goal of all training is victory in combat. Theory means nothing if you cannot apply it when your life depends on it."
Carl nodded. He agreed completely.
"Before we begin combat training, I need to assess your current level. Have you studied any fighting arts?"
"Some," Carl said mildly. "I practice regularly at home."
The understatement of the century. But Chiriku didn't need to know that—not yet.
"Kūkai!" Chiriku called out.
A young monk separated from the training group—perhaps seventeen or eighteen, lean and sharp-featured, with the confident bearing of someone who'd earned his place through hard work. He approached and bowed respectfully.
"Kūkai has the strength of a genin," Chiriku explained. "You'll spar with him. Kūkai—no ninjutsu, no chakra enhancement. I want to see his pure fighting ability."
"Understood, Abbot."
Kūkai's expression remained respectful, but Carl caught the subtle glint in his eyes. Ah. He's looking forward to this.
It made sense. Carl was the prince who'd arrived a month ago, received the Abbot's personal instruction, and paid five hundred million ryō for the privilege. To monks who'd trained for years with nothing but dedication, that probably rankled.
He wants to put me in my place, Carl realized. To show that rank and money don't matter on the training grounds.
Fair enough.
Carl would show him something too.
---
A circle of monks had gathered by the time they took their positions. Training had quietly stopped, attention shifting to this unexpected match between the prince-disciple and one of the temple's young fighters.
Carl stood relaxed, hands at his sides, weight balanced. He didn't adopt a fighting stance—not yet.
"Junior Brother," Kūkai said formally, "please instruct me."
Junior Brother. Technically correct—Carl had arrived later—but the slight emphasis suggested Kūkai didn't entirely mean it as a courtesy.
"Senior Brother," Carl replied evenly. "Please don't hold back."
Kūkai's eyes narrowed slightly. Then he moved.
It was fast by normal human standards. The young monk closed the distance in a heartbeat, fist driving toward Carl's midsection—a controlled strike, pulled slightly to avoid serious injury, but still intended to demonstrate the gap between them.
Carl watched it come.
Slower than I expected, he noted clinically. But this isn't Konoha. The Temple of Fire doesn't produce elite combat ninjas. And without chakra enhancement...
The fist reached the space where Carl's body had been.
But Carl wasn't there anymore.
He'd shifted sideways at the last instant—not a dramatic leap, just a subtle redirection of weight. His feet barely left the ground, toes brushing the dirt like a swallow skimming water. By the time Kūkai's punch completed its arc, Carl was already behind him.
"Senior Brother," Carl said quietly, close enough that his breath touched Kūkai's ear, "you should use chakra. Otherwise this won't be a fair match."
Kūkai spun, whipping a backfist toward Carl's head.
Carl leaned away, letting the strike pass within centimeters of his face. He didn't counter—not yet. He wanted to see more.
"Impossible—!"
Pride stung, Kūkai launched a furious combination. Punches and kicks flowed in rapid succession, each one faster than the last, drawing on years of temple training and genuine fighting instinct.
It wasn't bad technique. Against most opponents, it would have been overwhelming.
Against Carl, it was like watching someone fight underwater.
Every strike came with tells—shifts in weight, tensing of muscles, changes in breathing. Carl read them all without conscious effort, the product of a lifetime spent in life-or-death combat. He wove through the assault like smoke, never fully engaging, always precisely where Kūkai's attacks weren't.
The young monk's breathing grew ragged. Sweat beaded on his forehead. Frustration crept into his movements, making them sloppier, more predictable.
The watching monks had fallen silent.
"Kūkai," Chiriku's voice cut through the tension. "Use everything."
"If that's the case, then I won't hold back!"
Kūkai's chakra surged outward, wrapping his body in an invisible field of enhanced power. His muscles tensed, his movements sharpened, and when he launched himself at Carl again, the difference was immediately apparent.
Now we're talking, Carl thought.
The young monk's speed had nearly doubled. His strikes carried real weight behind them—not just muscle, but chakra-reinforced force that could shatter bone if it connected cleanly.
Carl stopped dodging.
His stance shifted. Where before he'd been fluid and evasive—the Swallow Form of Xingyiquan, designed for graceful avoidance—he now planted his feet and lowered his center of gravity. His hands curled into shapes that suggested claws more than fists.
Tiger Form. Direct. Powerful. Designed to meet force with greater force.
Kūkai's chakra-enhanced punch came in fast.
Carl intercepted it.
Not with a block—blocks were for people who wanted to absorb damage. Instead, he caught Kūkai's wrist at the exact moment of extension, when the arm was committed and couldn't easily retract. His other hand found the monk's elbow, and with a subtle rotation of his hips, he redirected the entire attack's momentum.
Kūkai stumbled past him, off-balance.
Carl didn't pursue. Not yet. He wanted to see more.
"He's fighting Kūkai without using chakra!"
The whispered exclamation came from somewhere in the crowd of watching monks. Carl ignored it, but he noted the shift in their attention. Where before they'd been expecting entertainment—the pampered prince getting a lesson in humility—now they were genuinely confused.
Kūkai recovered and came in again, faster this time, mixing punches with kicks in combinations that showed real training. His chakra enhancement made each strike a potential fight-ender.
Carl wove through the assault with economical movements, never retreating more than necessary, always maintaining his center. When openings appeared, he struck—not to injure, but to demonstrate. A palm-strike that stopped an inch from Kūkai's ribs. A knee that rose toward his chin and halted just before contact.
I could have ended this three times already, each near-miss said. I'm choosing not to.
The message wasn't lost on the watching monks. Or on Chiriku, whose expression had grown increasingly intent.
"The tiger leaves its cage!"
Carl's voice cut through the training ground as he finally committed to offense. His hands shaped themselves into tiger claws—fingers curved, palms angled—and he drove forward with explosive force.
Kūkai saw it coming. His eyes widened, recognizing that he couldn't dodge in time—
And then he vanished in a puff of smoke.
Carl's strike passed through empty air. A small stone clattered to the ground where Kūkai had been standing.
Kawarimi, Carl realized instantly. The Substitution Technique.
He'd learned the technique himself, practiced it for weeks. But knowing a jutsu intellectually and recognizing it in combat were different things. His mind had been operating on martial arts logic—where your opponent couldn't simply teleport out of danger.
Lesson learned. In ninja combat, always assume they have options you haven't considered.
"Katon: Gōkakyū no Jutsu!"
The warning came in the form of sudden heat against his back.
Carl spun to see Kūkai six meters away, cheeks puffed, hands completing a seal sequence. A massive fireball—easily two meters in diameter—erupted from his mouth and rocketed toward Carl's position.
Fire Release, Carl's mind catalogued even as his body reacted. C-rank ninjutsu at minimum. Contact would mean severe burns, possibly death.
There was no time for hand seals. No time for his own Substitution Technique.
But there was time for chakra.
Carl had been holding his sennin chakra in reserve throughout the fight, curious to see how far pure martial skill would carry him. Now he released it in a controlled burst, flooding his legs with enhanced strength.
He leaped.
The fireball passed beneath him, close enough that he felt the heat singe the bottom of his robes. He twisted in midair—the White Crane Spreads Its Wings, a movement designed for exactly this kind of aerial repositioning—and landed in a crouch facing Kūkai.
The young monk's expression shifted from triumph to disbelief.
"What—how did you—"
Carl didn't give him time to finish the question.
"The tiger descends the mountain!"
He exploded forward, channeling chakra through his entire body now. The enhancement was crude compared to what trained ninjas could achieve, but it was enough. His speed doubled. His strength tripled.
And his killing intent—honed through years of underground fighting where hesitation meant death—projected outward like a physical force.
Kūkai froze.
It wasn't a conscious decision. His body simply stopped, overwhelmed by the pressure emanating from the figure hurtling toward him. Every survival instinct screamed that resistance was futile, that this predator would destroy him if he moved wrong.
Carl's fist stopped two centimeters from Kūkai's face.
The training ground was utterly silent.
"Thank you for the instruction, Senior Brother." Carl's voice was calm, pleasant, as if they'd just finished a friendly game rather than a fight that had ended with near-death experiences on both sides. "I learned a great deal."
Kūkai blinked. The killing intent vanished as quickly as it had appeared, leaving him feeling faintly ridiculous for having been so thoroughly intimidated.
"I... you're welcome, Junior Brother." He swallowed hard. "Your skill is... far beyond what I expected."
Carl smiled and stepped back, allowing Kūkai space to recover his dignity.
And that's the difference between a fighter and a warrior, Carl thought. A fighter wins matches. A warrior controls whether the fight happens at all.
"Chuan. Come with me."
Chiriku's voice carried an undertone that Carl couldn't quite identify. Excitement, perhaps. Or the carefully controlled anticipation of someone who had just discovered something valuable.
Carl bowed to the assembled monks—a gesture of respect that cost him nothing and would help smooth over any resentment from his victory—and followed his teacher toward the practice hall.
The walk was silent, but Carl could feel Chiriku's attention on him like a physical weight.
He's reassessing everything, Carl realized. Every assumption he made about who I am and what I'm capable of.
Good. That meant more serious instruction was coming.
