The morning air in Konohagakure carried a crisp edge, the first hint of autumn whispering through the Academy's training grounds. Ryūzaki Itsuki arrived earlier than usual, his white curls tucked under a plain headband to dim his striking appearance. He stood alone near the edge of the field, practicing a series of slow, deliberate taijutsu forms, each movement precise yet restrained. The headache from yesterday's overuse of his Phenomenon Potential had faded, but a lingering caution remained. I can't let it control me, he thought, exhaling as he flowed from one stance to the next. Not yet.
The grounds began to fill with students, their chatter a mix of excitement and nervous anticipation. Iruka's announcement of a guest instructor had sparked wild speculation—some whispered of an elite jōnin, others of a legendary Sannin. Naruto Uzumaki barreled through the gates, his orange jacket a splash of chaos against the muted dawn. "Itsuki! You hear the rumors? I bet it's the Hokage himself!" he shouted, skidding to a stop and nearly tripping over Akamaru, who yipped in protest.
Itsuki smiled faintly, pausing his forms. "Doubt it. The Third's too busy for us rookies. Probably just a chūnin with a point to prove." His calm tone belied the curiosity stirring within. Whoever this instructor was, they'd be another test of his ability to blend in while his potential urged him to shine.
As the class gathered, Sasuke Uchiha arrived, his dark eyes scanning the field with a predator's focus. He lingered near the front, ignoring Naruto's loud attempts to goad him. Hinata Hyūga slipped in quietly, her lavender eyes briefly meeting Itsuki's before darting away, a faint blush coloring her cheeks. She'd been replaying his kindness to Naruto in her mind, a small beacon in her world of Hyūga pressures. Maybe today, she thought, I'll say something.
Iruka emerged from the Academy building, followed by a figure who silenced the crowd with their mere presence. Tall and lean, with silver hair tied back and a single visible eye glinting with sharp intelligence, Kakashi Hatake stepped forward. His jōnin vest and slouched posture radiated nonchalance, but the air around him crackled with authority. "Morning, kids," he said, his voice muffled slightly by his mask. "I'm Kakashi Hatake, here to teach you a lesson in precision. Don't expect me to go easy."
Naruto's jaw dropped. "No way! The Copy Ninja?!" Whispers erupted—Kakashi's reputation as an elite shinobi preceded him, tales of a thousand jutsu and lightning-fast battles circling the village like folklore.
Iruka raised a hand for silence. "Kakashi-sensei's here to assess your taijutsu fundamentals. He'll run a sparring gauntlet—one-on-one, no chakra, just technique. Observers will analyze. Show him what Konoha's future looks like."
Kakashi's eye crinkled in what might have been a smile. "Let's see if you're more than loudmouths and dreams. Line up."
The class formed a loose circle around a dirt-packed arena, the morning sun casting long shadows. Kakashi called names randomly, pitting students against each other in brief, intense spars. Kiba's wild lunges earned a raised eyebrow and a quick trip to the dirt. Sakura's cautious strikes showed promise but lacked power. Hinata, paired against Ino, moved with tentative grace, her Gentle Fist blocked by Kakashi's swift intervention before it could escalate. "Good form, but focus on intent," he told her, his tone encouraging yet firm. Hinata nodded, stealing a glance at Itsuki, who offered a subtle nod of support.
Naruto's turn came next, facing a burly classmate named Daichi. His attacks were a whirlwind of enthusiasm, all flailing limbs and zero strategy. Kakashi sidestepped effortlessly, redirecting Naruto's momentum to send him sprawling. "Energy's good," Kakashi said, "but you're a storm without a center. Think before you swing."
Sasuke followed, his spar against Shino Aburame a study in contrasts—Sasuke's precise kicks met Shino's calculated blocks, insects buzzing faintly at the edges. Kakashi ended it with a nod. "Not bad, Uchiha. But don't rely on talent alone." Sasuke's lips twitched, his pride stung but unspoken.
Finally, Kakashi's eye landed on Itsuki. "White hair. You're up. Against me." A ripple of surprise passed through the class—Kakashi rarely sparred directly with students. Itsuki's heart quickened, but his face remained calm as he stepped into the circle.
"Rules are simple," Kakashi said, assuming a relaxed stance. "Land one clean hit, or survive three minutes. No chakra, just taijutsu. Begin."
Itsuki's Phenomenon Potential stirred, his mind dissecting Kakashi's posture—the slight tilt of his shoulders, the loose grip of his hands. He'd seen jōnin spar in the village, their movements etched into his eidetic memory. Kakashi was a different beast, but patterns were patterns. Itsuki moved first, a cautious jab aimed at Kakashi's chest, testing his reactions.
Kakashi swayed aside, almost lazily, but his eye gleamed with interest. "Not bad. Try harder." Itsuki pressed forward, weaving a series of strikes—low kick, feint, uppercut—each drawn from fragments of observed techniques. Kakashi countered effortlessly, his movements a blur, but he didn't strike back, only deflected. The class watched, breathless, as Itsuki's speed increased, his body adapting mid-motion, redirecting a missed punch into a spinning elbow.
He's fast, Itsuki thought, his mind racing to predict Kakashi's counters. His Potential hummed, analyzing angles and openings, but a faint ache pulsed behind his eyes—the strain of pushing his body to match his mind's calculations. On his final move, a daring leap to land a palm strike, Kakashi caught his wrist, twisting gently to pin him to the ground.
"Time's up," Kakashi said, releasing him. "No hit, but you lasted. Impressive for a civilian." His tone was neutral, but his gaze lingered, sharp and probing. "Where'd you learn to move like that?"
Itsuki rose, brushing dirt from his tunic, his calm facade intact despite the pounding in his skull. "Just... watching others, Sensei. And practicing." The half-truth felt heavier each time he spoke it.
Kakashi hummed, unconvinced but letting it slide. "Keep at it. Precision's your strength, but don't let it isolate you." He turned to the class. "Next pair!"
As Itsuki rejoined his classmates, Naruto clapped him on the back. "Man, you almost had him! That was awesome!" Sasuke, observing from the sidelines, said nothing, but his eyes burned with a mix of rivalry and calculation. Hinata, tasked with analyzing Itsuki's spar, scribbled notes furiously, her handwriting shaky with awe. He's so controlled, she wrote, like he sees everything at once.
The gauntlet continued, but Itsuki's performance lingered in the air. During a break, he sat alone, massaging his temples to ease the ache. His Potential was a gift, but it demanded focus—too much, and his body protested. I need to pace myself, he thought, recalling Miko's warning about dulling blades.
Flashback: Two years ago, in the orphanage's backyard. Itsuki, ten, practiced a stolen taijutsu form under moonlight, his small frame trembling from exertion. Miko caught him, her eyes soft with worry. "You push too hard, Itsuki. Talent like yours is rare, but it's a fire that can burn you out. Balance it with care—for yourself and others." He'd nodded, but the drive to prove himself had only grown, fueled by the empty spaces where family should have been.
Back in the present, Naruto plopped beside him, oblivious to his introspection. "Hey, you okay? You look kinda pale. Kakashi didn't hit you that hard, did he?"
Itsuki chuckled softly. "Just tired. That was... intense." He glanced at Naruto, whose grin never wavered. "You did well out there. Keep working on your center, like Kakashi said."
Naruto beamed. "Yeah, yeah, I'll get it! You're gonna help me, right? Team Awesome, you and me!" His enthusiasm was a balm, easing the weight of Kakashi's scrutiny.
As the session ended, Kakashi addressed the class. "You've got potential, but potential's nothing without effort. Tomorrow, we're back to Iruka's lessons. Don't slack." He vanished in a puff of smoke, leaving the students buzzing.
Hinata approached Itsuki hesitantly as they packed up, her voice barely above a whisper. "Um... Itsuki-san? Your spar was... really amazing. I-I wrote some notes, if you want to see..." She held out her notebook, her fingers trembling slightly.
Itsuki blinked, surprised by her initiative. "Thanks, Hinata. I'd like that." He took the notebook gently, their fingers brushing for a fleeting moment. Her notes were detailed, praising his fluidity but suggesting he vary his angles to avoid predictability. She's sharp, he thought, a spark of respect kindling.
Naruto, nearby, grinned mischievously. "Ooh, Itsuki's got a fan!" Hinata flushed crimson and scurried away, leaving Itsuki to roll his eyes.
"Knock it off, Naruto," he said, but a small smile tugged at his lips. The moment, brief as it was, felt like a step toward connection. But as he and Naruto headed to the library for their project, Sasuke's gaze followed, his thoughts dark and unreadable. Kakashi, watching from a distant rooftop, noted the white-haired boy's name in his mental ledger.
And in the quiet of the Hyūga compound, Hinata clutched her notebook, her heart racing with a courage she hadn't known she possessed. The Academy was a crucible, and for Itsuki, the sparks of rivalry and bonds were only beginning to ignite.
