# Shadow of the Fox: The Forgotten Heir

## Chapter 1: A Hero's Shadow

Konoha blazed with festival lights, paper lanterns swaying in the autumn breeze as villagers thronged the streets with masks and noisemakers. Children darted between food stalls, their laughter punctuating the steady drum beats that pulsed through the village center. October 10th—the anniversary of the Nine-Tails attack. Twelve years since the night that should have ended in tragedy, now transformed into Konoha's grandest celebration.

Naruto Uzumaki-Namikaze stood alone on the Hokage monument, the wind tousling his spiky blonde hair as he gazed down at the festivities. From this height, the celebration looked like a river of light flowing through the village streets. His fingers absently traced the stone contours of his father's carved face beneath his feet.

"Celebrating without the guest of honor again, huh?" he murmured to himself, his voice almost lost in the wind.

The crack and bloom of fireworks painted his face in momentary flashes of blue and gold. Each explosion echoed in his chest, a hollow reminder that today was his birthday too—not that anyone seemed to remember that detail anymore.

Twelve years ago, the Nine-Tails had nearly destroyed Konoha. Twelve years ago, his father—the legendary Fourth Hokage—and his mother had performed the impossible. Rather than sacrificing themselves as legend said they'd planned, they'd modified the sealing jutsu at the last moment, splitting the Nine-Tails' chakra between the twins born minutes after Naruto—Menma and Mito.

The village called it the Miracle of the Namikaze.

Naruto called it the day he became invisible.

A particularly large firework burst overhead, cascading red and gold sparks against the indigo sky. Naruto sighed, tucking his hands into his pockets. He should head home. They'd notice if he missed the family ceremony entirely.

Or maybe they wouldn't.

---

The Namikaze compound hummed with activity. Servants bustled through the main house, carrying platters of food and arrangements of fire lilies—Kushina's favorite. Through the open shoji doors, Naruto could see his father in his formal white Hokage robes, entertaining a circle of village elders and clan heads in the main room.

Naruto slipped through the side entrance, keeping to the shadows out of habit. He'd perfected the art of moving through his own home unnoticed—a skill that should have worried his parents, had they ever caught on.

"Big brother!"

A small weight crashed into his legs, nearly toppling him. Mito's crimson hair bounced in pigtails as she grinned up at him, her round face alight with excitement. At eight years old, she was the only one who consistently seemed to see him.

"Where were you? Mom's been setting up forever, and Menma's being a total jerk about his new jutsu," she rattled off, tugging at his hand.

Naruto managed a small smile, ruffling her hair. "Just watching the fireworks. What new jutsu?"

Mito rolled her eyes dramatically. "Dad taught him this swirly chakra ball thing yesterday, and now he won't shut up about—"

"The Rasengan," came a smug voice from the hallway. Menma leaned against the doorframe, arms crossed over his chest. At ten, he was already developing their father's lean build, though his red-streaked black hair came from neither parent—a side effect, they said, of containing the Nine-Tails' yang chakra. "Not that you'd know about it, since you're never around for training."

Naruto's jaw tightened, but he kept his expression neutral. "I'm around. Dad's just usually busy with you two."

"Because we're the ones who—" Menma began, only to be cut off by their mother's arrival.

Kushina Uzumaki swept into the hallway like a force of nature, her long red hair trailing behind her and her ceremonial kimono rustling with each step. Even after three children and the stress of being the Hokage's wife, she remained strikingly beautiful—and formidable.

"There you are, Naruto! The ceremony starts in ten minutes, and you're not even changed!" She thrust a folded blue kimono into his arms. "Quickly now—your father wants the whole family present when he gives the address."

Her eyes, so like his own, barely lingered on his face before she turned to Menma. Her expression softened as she straightened his already immaculate collar. "You'll stand with your father at the center, remember? When he signals, you and Mito will release just a touch of chakra—just like we practiced."

"I know, Mom," Menma replied, but he leaned into her fussing all the same.

Naruto clutched the kimono, watching the exchange with a familiar hollow feeling spreading through his chest. "Mom," he said quietly, "it's also my—"

"Kushina! Is everyone ready?" His father's voice called from the main room, warm and commanding all at once.

Kushina straightened, her attention immediately diverted. "Coming, Minato! Children, hurry along now."

She swept back the way she'd come, gathering Menma and Mito with her like ducklings, leaving Naruto standing alone in the hallway.

"—birthday," he finished to no one.

---

The main garden of the Namikaze compound had been transformed into a reception worthy of the Hokage. Paper lanterns hung from every tree, casting warm light over the gathering of Konoha's elite. At the center, a stone altar had been erected years ago to commemorate the sealing, engraved with the complex formulas that had saved the village.

Naruto stood at the edge of the gathering, tugging uncomfortably at his kimono collar as he watched his father address the crowd. Minato Namikaze commanded attention effortlessly, his charisma as much a weapon as his legendary speed.

"Twelve years ago," Minato was saying, his voice carrying easily across the hushed crowd, "our village faced its darkest hour. The Nine-Tails threatened not just our homes, but our very future."

Naruto had heard this speech, or variations of it, every year of his life. He could recite it from memory by now.

"Through sacrifice and love," Minato continued, placing one hand on Menma's shoulder and the other on Mito's, "we found a path forward. Not just survival, but a new strength for Konoha."

The twins stood straight-backed and solemn on either side of their father, perfect miniature shinobi. Menma's face held the serious expression he reserved for public appearances, while Mito fidgeted slightly, though only those who knew her well would notice.

Naruto scanned the crowd, noting the familiar faces. There was old man Third, retired now but still respected; Kakashi-sensei, his father's former student, looking bored as usual with his face buried in that book; Jiraiya of the Sannin, his father's mentor, watching the twins with particular intensity.

It was Jiraiya who had first spoken the prophecy that had shaped Naruto's life from the shadows. Three years ago, he'd returned from Mount Myōboku with news that had changed everything: the toad elders had foreseen twin saviors who would bring peace or destruction to the shinobi world. Twins who carried divided halves of the greatest power.

From that day forward, his parents' already considerable attention on the twins had transformed into near-obsession. Special training, private tutoring, secret techniques—all reserved for the children of prophecy.

Naruto had been twelve then, already a genin, already struggling to catch his parents' eye. The prophecy had simply cemented what was already becoming clear: in the grand story of the Namikaze family, he was merely a footnote.

"And now," Minato said, drawing Naruto's attention back to the ceremony, "I ask my children to demonstrate the perfect harmony they've achieved with the power entrusted to them."

At their father's nod, Menma and Mito formed identical hand signs. A soft glow emanated from their bodies—red from Menma, blue from Mito—as they released carefully controlled amounts of the Nine-Tails' chakra. The energies swirled upward, intertwining in a double helix above the altar before dispersing in a shower of luminescent particles.

The crowd gasped in appreciation, then broke into applause. Kushina beamed from behind them, pride radiating from every line of her body.

Naruto watched his family tableau—father, mother, special children—feeling like a ghost at his own family gathering. He'd performed a flawless Shadow Clone Jutsu at age ten, mastered chakra control that jonin respected, developed taijutsu combinations that had his academy teachers buzzing with praise. None of it ever seemed to register at home.

As the formal ceremony concluded and the reception began in earnest, Naruto found himself drifting further to the periphery. Dignitaries and clan heads swarmed around his parents and siblings, offering congratulations and thinly veiled political overtures.

"Quite the spectacle, isn't it?" came a lazy voice from behind him.

Naruto turned to find Kakashi standing there, visible eye curved in what might have been a smile beneath his mask.

"Kakashi-sensei," Naruto acknowledged with a nod. Though not officially his instructor, the jonin had occasionally offered pointers when their paths crossed at the training grounds.

"Not joining the family celebration?" Kakashi asked, his tone casual yet observant.

Naruto shrugged, turning back to watch as Jiraiya lifted Mito onto his shoulders, the little girl giggling as she towered over the crowd. "They seem busy."

Kakashi made a noncommittal noise. "I noticed your shadow clone technique has improved. The one you used during the market district exercise last week was nearly flawless."

Surprise flickered across Naruto's face. "You saw that?"

"I see a lot of things," Kakashi replied cryptically. "Including talent that others might miss."

Before Naruto could respond, a servant approached with a message that the dinner was about to be served in the main hall. Kakashi nodded and wandered away with a lazy wave, leaving Naruto with an odd feeling of having been assessed.

---

The dining hall gleamed with candlelight, the long table set with the family's finest dishware. At the head sat Minato, with Kushina to his right and honored guests arranged by importance down the sides. Naruto found himself seated near the far end, between a minor councilman and one of his mother's distant relatives.

Servants brought course after course—Kushina had clearly spent days planning the menu. Conversation flowed like the sake being poured for the adults, predominantly centered on village politics, the twins' progress, and reminiscences about the Nine-Tails attack.

Halfway through the main course, Jiraiya stood, raising his cup in a toast. The room quieted immediately.

"To Minato and Kushina," he began, his deep voice filling the hall, "whose courage twelve years ago saved not just this village, but perhaps the future of the shinobi world itself."

Murmurs of agreement rippled through the guests.

"And to Menma and Mito," Jiraiya continued, his gaze fixing on the twins, who straightened under his attention. "Two extraordinary children who carry not just power, but destiny in their hands. The prophecy speaks of twins who will either save our world or destroy it." He smiled broadly. "Based on their progress, I'd wager heavily on the former!"

Laughter and applause followed. Minato nodded appreciatively at his mentor while Kushina beamed at her youngest children.

"I've spent the past month observing their training," Jiraiya went on, "and I must say, the control they're developing is unprecedented for their age. Which brings me to my announcement."

He set down his cup, his expression growing more serious. "After much discussion with your parents, we've decided it's time to begin the next phase of your training. Starting next month, I'll be personally overseeing a special regimen focusing on harmonizing your unique chakra signatures."

Menma's eyes widened in barely contained excitement, while Mito bounced in her seat.

"Really, Pervy Sage?" Mito squealed, using the nickname that made several guests choke on their drinks.

Jiraiya winced at the name but nodded. "Really, little princess. Your father will join us when his duties permit, and your mother has already designed the chakra control exercises."

Naruto set down his chopsticks, his appetite vanishing. Another special training program. Another family activity that wouldn't include him. He glanced toward his parents, wondering if either would remember to mention that he, too, might benefit from training with a legendary Sannin.

Neither did. Instead, conversation exploded around the table as guests offered congratulations and speculated on the twins' potential.

"Excuse me," Naruto murmured, rising from his seat. No one noticed as he slipped away from the table, through the sliding doors, and into the garden beyond.

The night air felt cool against his face after the stuffiness of the dining hall. The garden was deserted now, lanterns still glowing but the festivities moved indoors. Naruto wandered to the koi pond at the far end, watching the fish make lazy circles in the moonlit water.

Something inside him had gone very quiet and still. Twelve years old today. Not that anyone had mentioned it. His birthday had been swallowed by commemoration years ago, becoming an afterthought even to his parents.

He picked up a smooth stone from the pond's edge and skipped it across the water, disturbing the koi's peaceful patterns.

"Twelve," he whispered to himself. "Twelve years of being the warmup act."

In the distance, he could hear laughter from the dining hall. They hadn't noticed his absence yet. Might not at all.

A familiar determination hardened in his chest—the same feeling that drove him to train alone for hours after academy classes, to perfect techniques without guidance, to push himself beyond what instructors expected. If his path wouldn't be illuminated by his parents' attention, he would carve it through the darkness himself.

Naruto straightened his shoulders, blue eyes reflecting the moon as they narrowed with resolution. Let them have their prophecy and their special training. Let them focus on the twins with their perfect chakra control and their destiny.

He would find his own way. Become strong on his own terms. Forge a path so brilliant they couldn't help but turn their heads and see him—truly see him—at last.

The stone sank beneath the pond's surface, disappearing into the depths as Naruto made a silent vow to himself under the indifferent moon.

# Shadow of the Fox: The Forgotten Heir

## Chapter 2: The ANBU Shadow

The forest pulsed with nighttime energy as Naruto's fist slammed into the training post again and again. Sweat gleamed on his forehead, catching moonlight as it dripped onto the forest floor. Blood smeared across his knuckles, but the pain was secondary to the burning in his lungs and the satisfying crack of impact.

"One hundred ninety-eight... one hundred ninety-nine... two hundred!"

His final punch splintered the weathered wood. Naruto stumbled back, chest heaving, and dropped to one knee. The training ground lay deep in Konoha's eastern forest—far enough from the village that no one would hear him, far enough from home that no one would look for him.

Perfect silence. Perfect solitude.

He tilted his head back, letting cool air rush into his burning lungs. Stars pierced the canopy above, indifferent to his exhaustion. After the festival two nights ago, he'd doubled his training regimen—five hours each night after his team's missions. If no one would teach him, he'd teach himself.

"Your form is decent, but your left side leaves you exposed."

Naruto whirled, kunai materializing in his hand as he dropped into a defensive stance. The voice had come from everywhere and nowhere.

A silver-haired figure melted from the shadows, hands casually tucked into pockets. Kakashi Hatake stood at the edge of the clearing, his visible eye lazily sweeping over the destruction Naruto had wrought upon the training area.

"Kakashi-sensei? What are you doing out here?" Naruto lowered his kunai but didn't relax his stance. Even among jōnin, Kakashi's ability to move undetected was legendary.

"I could ask you the same question," Kakashi countered, stepping into the moonlight. "Most genin are home at this hour. Most genin also don't train until their hands bleed."

Naruto glanced down at his torn knuckles and shrugged. "It's quiet here."

"Hmm." Kakashi circled the clearing, nudging a shattered log with his foot. "You've been coming here for a while. Three weeks, if I'm not mistaken."

The revelation sent a jolt up Naruto's spine. "You've been watching me?"

"Occasionally." Kakashi's tone remained casual, but his eye fixed on Naruto with an intensity that belied his relaxed posture. "I make it a point to know when someone's destroying forest property after hours."

Naruto winced, glancing at the battered training equipment. "I'll replace everything I break."

"That's not my concern." Kakashi moved with sudden fluidity, appearing directly before Naruto. "Show me your Shadow Clone technique."

"What? Now?"

"Unless you have a pressing engagement elsewhere." Kakashi gestured vaguely at the empty forest.

Naruto hesitated only a moment before his hands flashed through the signs. "Shadow Clone Jutsu!"

The clearing erupted with smoke, and when it cleared, twenty perfect duplicates of Naruto stood in formation. Not a flicker or transparency among them—each clone solid and combat-ready.

Kakashi's eye widened a fraction—the equivalent of open-mouthed shock from anyone else. "Interesting. Dispel them."

The clones vanished in puffs of smoke, leaving only the original Naruto, watching Kakashi warily.

"Twenty perfect clones, no visible chakra drain, and excellent distribution around the clearing." Kakashi circled him slowly, like a predator assessing potential. "Who taught you to refine the technique to this level?"

"Nobody," Naruto admitted. "I found a scroll in my dad's study that explained the basics. The rest was just... practice."

"Practice," Kakashi repeated flatly. "Most chūnin can't produce five combat-ready shadow clones without exhaustion."

Naruto shifted uncomfortably under the scrutiny. "Is there something wrong with my technique?"

"On the contrary." Kakashi stopped circling. "It's exceptional. As are your stealth capabilities. I almost missed your return from the Hokage monument two nights ago. You crossed three ANBU patrol routes without detection."

Pride flickered briefly across Naruto's face before he controlled his expression. "I just know the patrols. It's not a big deal."

"The patrols change nightly," Kakashi countered. "And they're not posted for the public."

A moment of silence stretched between them, broken only by the distant hooting of an owl. Naruto felt as though he were being dissected beneath that single, calculating eye.

"Tell me, Naruto," Kakashi said finally, his voice dropping to a near-whisper, "what do you know about ANBU?"

---

Dawn painted the Hokage's office in shades of gold as Minato shuffled papers across his desk. He'd been working since before sunrise, trying to clear urgent matters before his promised training session with Naruto.

The door opened without a knock, and Minato glanced up to see his advisor entering with a stack of reports.

"The intelligence from the northern border," the advisor said, placing the documents on the already crowded desk. "Marked urgent by the captain."

Minato suppressed a sigh. "Thank you. I'll review them immediately."

His eyes flicked to the clock on the wall. Seven-thirty. He'd promised to meet Naruto at the family training ground at eight. Just enough time to scan the reports before—

"Lord Hokage?" A breathless chūnin appeared in the doorway. "Lord Jiraiya has returned with Menma and Mito. They're experiencing chakra fluctuations after this morning's exercise."

Minato was on his feet instantly. "How severe?"

"Mito seems stable, but Menma's seal is showing irregularities. Lord Jiraiya requested your presence at the secure training facility."

Minato's mind raced through calculations and possibilities. Menma's control had been advancing quickly—perhaps too quickly. If the seal was responding negatively to the increased chakra flow...

"Tell them I'm on my way," he said, already gathering the specialized sealing tools he kept in his desk. "And send word to my wife."

Only as he reached the door did Minato remember his other commitment. He paused, guilt flickering across his features.

"One more thing," he added. "Find my son Naruto. Tell him I'll need to reschedule our training session. Family emergency."

The chūnin nodded, and Minato vanished in a yellow flash, the urgent matters of prophecy and power taking precedence once again.

---

Naruto sat on the smooth stone of the training ground, watching the sun climb higher in the sky. Eight o'clock had come and gone. Then eight-thirty. Now the village bells tolled nine, their sound carrying clearly across the Namikaze compound's private grounds.

He traced patterns in the dirt with a kunai, carving aimless spirals that matched the churning in his stomach. His father was punctual to a fault—famous for it, even. If he was late, it meant something serious had happened.

Or something more important had come up.

Footsteps approached, and Naruto looked up with hope that withered instantly. Not his father, but one of the Hokage's messengers, looking vaguely uncomfortable.

"Naruto Namikaze?" the chūnin asked formally, though they both knew who Naruto was.

"That's me." Naruto stood, dusting off his pants. "Is my father okay?"

The messenger nodded quickly. "Lord Hokage is fine. He asked me to inform you that today's training session needs to be rescheduled due to a family emergency."

The words hit like a physical blow. "Family emergency?" Naruto repeated slowly. "What happened?"

"Something about the young lord and lady's training with Lord Jiraiya. I don't have the details." The messenger shifted, clearly eager to depart. "Lord Hokage will contact you when things are settled."

"Right," Naruto said hollowly. "Thank you for letting me know."

When the messenger left, Naruto remained standing in the empty training ground, the words echoing in his head. Family emergency. Not your brother and sister. Not even the twins. Just family emergency—as though he weren't part of that family at all.

His hand tightened around the kunai, knuckles whitening. How many times had this happened? Four? Five? He'd lost count of the canceled training sessions, the forgotten promises, the "we'll make it up to you next time" that never materialized.

Kakashi's words from the previous night sliced through his thoughts: "ANBU exists in shadow so the village can stand in light."

An existence in shadow. Working in darkness while others claimed the light. It struck a chord so deep it resonated in his bones.

Decision crystallized like ice in his veins. Naruto pocketed the kunai and turned toward the village, his path suddenly clear.

---

"I was beginning to think you'd changed your mind."

Kakashi's voice drifted down from the massive oak tree where he perched, seemingly engrossed in his infamous orange book. The meeting place—a forgotten memorial stone deep in the forest—stood overgrown with moss and vines, hidden from casual discovery.

Naruto stepped into the small clearing, determination etched across his features. "I want in. Whatever training program you were talking about—I want in."

Kakashi snapped his book closed and dropped to the ground with feline grace. "What changed since last night?"

"Nothing changed," Naruto said, his voice harder than Kakashi had ever heard it. "Everything's exactly the same as it's always been. That's the problem."

Understanding flickered in Kakashi's visible eye. He'd seen enough in the Hokage's office this morning to guess what had transpired.

"ANBU isn't a fallback plan for disgruntled genin," Kakashi warned, circling Naruto slowly. "It's not a place to hide from family problems. It's the shadow corps—Konoha's most dangerous, most elite operatives."

"I know what ANBU is," Naruto countered. "My father created most of your operating procedures."

"Then you should also know we don't recruit twelve-year-olds."

"You were thirteen when you joined."

Kakashi paused, genuinely surprised. "You've done your research."

"I notice things," Naruto said simply. "Even when people think I don't."

Something shifted in Kakashi's demeanor—a subtle change from testing to evaluating. "The training would be brutal. Beyond anything you've experienced. Beyond anything your father or the Academy would approve of."

"Good."

"You would maintain your regular duties and team assignments. No one—not your teammates, not your parents, not even the Hokage himself—could know about your training."

Naruto's eyes hardened. "They barely notice me when I'm standing right in front of them. They won't notice this."

The bitterness in those words made even Kakashi, hardened as he was, inwardly wince. But it was precisely that drive—that burning need to be seen, to prove himself—that made the boy potentially valuable.

"Last warning," Kakashi said, his voice dropping to a deadly serious tone. "Once you start this path, there's no going back. ANBU changes you. It has to, for you to survive it."

The wind rustled through the clearing, stirring fallen leaves around their feet. In that moment, silhouetted against the ancient memorial stone, Naruto looked older than his years—a child forced to grow up too quickly, shouldering burdens no one had helped him carry.

"I'm already changing," he said quietly. "This way, at least it serves a purpose."

Kakashi studied him for a long moment before nodding once, decisively. "Be at the east village gate at midnight. Bring nothing with you. Tell no one where you're going." He turned to leave, then paused. "And Naruto? From this point forward, trust no one but your ANBU handlers. Not even me, when I'm in my public role."

"Understood."

As Kakashi vanished in a swirl of leaves, Naruto gazed up at the shifting canopy above, watching sunlight filter through in dappled patterns. Somewhere across the village, his family was dealing with their "emergency"—their special children with their special powers and their special destiny.

Let them have their prophecy. He would forge his own fate in shadow and steel.

---

"Again!" Sasuke snapped, dark eyes narrowed in frustration. "You're not focusing, deadlast!"

Naruto gritted his teeth and formed the hand signs once more, concentrating on molding his chakra precisely as their substitute instructor had demonstrated. The simple earth wall jutsu should have been easy for genin their level, but his mind kept wandering to the training that awaited him tonight.

"Earth Style: Mud Wall!"

The ground rumbled, and a wall of compacted earth rose before him—waist-high and crumbling at the edges, but substantially better than his previous attempts.

"Still pathetic," Sasuke muttered, glancing at his own perfect barrier, "but at least it might stop a falling leaf now."

"Not everyone's born perfect, Sasuke," Sakura interjected from her position near the stream, where her own earth wall stood at shoulder height. Her green eyes flicked between her teammates with evident concern. "Naruto's trying."

"Trying isn't good enough on a battlefield," Sasuke retorted, but there was less bite in his words. He turned to Naruto with a scrutinizing gaze. "You mastered water walking in two days. This should be easier."

Naruto shrugged, avoiding Sasuke's too-perceptive stare. The truth was, he'd been deliberately holding back during team training—keeping his true skills hidden after Kakashi's warning to maintain his current persona.

"I'm just tired," he offered lamely. "Didn't sleep well."

"Hmph." Sasuke clearly didn't believe him, but their substitute jōnin leader called for them to wrap up before he could press further.

As they gathered their equipment, Sakura fell into step beside Naruto. "Are you sure you're okay?" she asked quietly. "You've seemed... distant lately."

For a moment, Naruto was tempted to confide in her—to tell someone, anyone, about the double life he'd begun leading. Three weeks of secret night training had left him perpetually exhausted, his body constantly sore from pushing limits he hadn't known existed.

Instead, he forced a grin. "Just working on some personal training. Nothing to worry about."

"Personal training?" Sasuke appeared at his other side, eyes narrowed suspiciously. "What kind?"

"The personal kind," Naruto shot back, quickening his pace. "Don't you have clan techniques to perfect or something?"

A flash of pain crossed Sasuke's features before his usual mask of indifference slammed back into place. "Whatever. Just don't drag the team down with your secrets, Namikaze."

Guilt twisted in Naruto's stomach at the low blow. Sasuke, of all people, understood what it meant to live in the shadow of expectations. Since the Uchiha massacre years ago, he'd carried the weight of his entire clan's legacy alone.

"Sorry," Naruto muttered. "That was out of line."

Sasuke's response was a barely perceptible nod before he veered away toward the Uchiha compound—empty save for him, yet still his home.

Sakura lingered a moment longer, concern evident in her expression. "We're a team, Naruto. If something's wrong, you can tell us."

Her kindness hit harder than Sasuke's suspicion. Naruto managed a smile that didn't quite reach his eyes. "Everything's fine, Sakura. Really."

As she walked away, Naruto checked the position of the sun. Four hours until he needed to report for his first real ANBU assessment. Four hours to rest, to prepare, to steel himself for whatever was coming.

Four hours to remind himself why he'd chosen this path in the first place.

---

The tunnels beneath Konoha ran deeper than most villagers knew, a labyrinth of passages carved by generations of shinobi preparing for sieges that most had never seen. Naruto followed the masked ANBU operative through the pitch-black corridor, relying on memory and heightened senses rather than light.

Three weeks of preparation had led to this moment. Three weeks of learning to move without sound, to breathe without being heard, to kill with precision rather than power. Three weeks of training his body past exhaustion while maintaining his public persona of a middling genin with occasional flashes of potential.

The tunnel opened into a vast chamber lit by sparse torches. Seven masked figures stood in formation, their identities concealed behind animal visages. At their center, a man in a bear mask waited, his posture radiating authority.

"Candidate," the Bear-masked leader addressed Naruto without preamble. "You have been recommended for preliminary ANBU assessment by Captain Hound." He gestured toward a figure in a dog mask that Naruto recognized as Kakashi, despite the disguise. "This evaluation will test your physical capabilities, mental resilience, and aptitude for covert operations."

Naruto stood straighter, focusing on controlling his breathing as he'd been taught. Show no fear. Show no doubt.

"You will face three trials," Bear continued. "Failure in any will result in immediate termination from the program and memory suppression of all you have learned."

The threat hung in the air between them. Memory suppression was rarely used outside the highest security protocols—a jutsu that could selectively erase weeks or months of a person's experiences.

"I understand," Naruto said, his voice steadier than he felt.

Bear nodded once. "Then we begin. Trial one: Evasion."

Without warning, the chamber plunged into complete darkness. The metallic sound of weapons being drawn echoed from all directions, and Naruto's instincts screamed danger.

"Evade for ten minutes," Bear's voice reverberated through the chamber. "Any strike that would draw blood counts as failure."

The first attack came from behind—a whistling sound cutting through the air toward his neck. Naruto dropped and rolled, feeling the blade pass millimeters above his head. He didn't waste breath or chakra on shadow clones—that would only give away his position in the darkness.

Instead, he relied on the sensory training Kakashi had drilled into him, focusing on the subtle shifts in air pressure, the nearly imperceptible sounds of breathing and movement that betrayed his hunters' positions.

A presence to his left—he twisted sideways as a blade sliced through the space he'd occupied. Footsteps from the right—he backflipped onto a wall, adhering with chakra as another ANBU passed beneath him.

Minutes blurred together in a deadly dance. Naruto moved constantly, never establishing a pattern, using the darkness as his ally rather than his enemy. When cornered, he employed the substitution technique Kakashi had refined with him, replacing himself with small objects he carried specifically for this purpose.

Just as his lungs began burning from exertion, Bear's voice cut through the darkness. "Time. Stand down."

Torches flared to life, revealing the seven ANBU operatives positioned throughout the chamber. Naruto stood in the center, breathing heavily but unscathed.

Bear tilted his masked head slightly—a gesture of mild surprise. "Impressive spatial awareness," he noted. "Trial two: Information extraction."

A panel in the wall slid open, revealing a complex array of papers, scrolls, and maps scattered across a desk. A timer appeared on the wall: five minutes.

"Memorize everything of tactical significance," Bear instructed. "You will be questioned afterward."

Naruto approached the desk, his mind shifting into analytical mode. This was the true test—not just his physical capabilities, but his potential value as an intelligence operative.

The documents contained mission reports, personnel records, encryption keys, and border patrol schedules—all deliberately arranged in chaotic fashion to challenge his ability to prioritize information. Naruto's eyes darted from page to page, his mind cataloging details with the precision Kakashi had instilled during their secret training sessions.

Names, dates, locations, patterns. He scanned troop movements along the northern border, memorized the rotation schedule for guard posts at the village gates, absorbed the encryption key for next month's ANBU communications.

When the timer reached zero, the documents disappeared behind the wall panel, and Bear stepped forward.

"Now," he said coldly, "tell me about the security vulnerability at the western outpost."

Naruto didn't hesitate. "Three-man team instead of the standard four, with no sensory-type among them. Rotation schedule creates a blind spot every third day during the 0200 to 0230 shift change. The terrain provides cover for approach from the southwest ravine."

For forty-five grueling minutes, Bear and the other ANBU operatives fired questions about the documents. Naruto answered with increasing confidence, pulling details from his memory and connecting disparate pieces of information to reveal patterns that might otherwise have gone unnoticed.

When the questioning finally ceased, even through the mask, Naruto could sense Bear's grudging approval.

"Final trial," Bear announced. "Tactical scenario."

The chamber transformed before Naruto's eyes as ANBU members formed hand signs in unison. A genjutsu materialized, creating the illusion of a border town nestled in mountainous terrain. Miniature figures moved through the streets—civilians and enemy shinobi intermingled.

"Infiltrate the compound at the town center," Bear instructed, pointing to a fortified building. "Extract the intelligence scroll and eliminate the commanding officer. Civilian casualties will result in failure. Detection by enemy forces will result in failure."

Naruto studied the scenario, analyzing guard patterns and civilian movements. This was the culmination of everything Kakashi had taught him—not brute force, but calculation, precision, and subtlety.

He formed a plan, explaining his approach in the detached, clinical language of an ANBU operative rather than an excitable genin. "I'll create a diversion in the market district using a timed explosive tag—non-lethal, smoke-based. While attention is diverted, I'll infiltrate through the sewage system, which appears to connect to the compound's lower levels based on the infrastructure layout."

As Naruto outlined each step of his plan, he noticed the ANBU members exchanging glances. Even Kakashi, identifiable only by his stance, seemed to straighten with interest.

"The commanding officer appears to have a routine—tea on the eastern balcony at sunset. A poisoned senbon from the adjacent rooftop would be silent, precise, and could be mistaken for natural causes, particularly if laced with a toxin that mimics heart failure."

Bear raised a hand, ending Naruto's explanation. The genjutsu dissolved, returning the chamber to its original state.

"Your approach," Bear said slowly, "prioritizes stealth and minimizes risk. You identified the target's routine, exploited structural weaknesses, and proposed an elimination method that would delay discovery." He paused. "These are not typically the tactics of a genin."

"I'm not a typical genin," Naruto replied, meeting the blank mask with unwavering eyes.

The ANBU operatives gathered in a tight circle, conferring in whispers too low for even Naruto's trained ears to detect. When they broke formation, it was Kakashi who stepped forward, his dog mask tilted toward Naruto.

"The candidate has displayed exceptional aptitude in evasion, information processing, and tactical planning," Kakashi stated formally. "I recommend provisional acceptance into the training program, subject to continued evaluation."

Bear nodded once. "Recommendation accepted. Candidate will begin phase two training tomorrow night." He turned to Naruto, his mask revealing nothing of the face behind it. "You are now designated Trainee Fox. Your public identity remains unchanged. Your ANBU existence is classified at the highest level."

The name sent a shiver down Naruto's spine. Fox—the very creature sealed within his siblings, the beast that had defined his family's legacy and overshadowed his existence.

Now it would become his shield, his identity in the shadows.

"Dismissed," Bear ordered. "Report to entrance point seven tomorrow at 2300 hours."

As the ANBU operatives vanished one by one, Kakashi lingered last, his masked face impossible to read.

"You surprised them," he said quietly. "That rarely happens."

Pride flickered through Naruto's exhaustion. "I surprised myself."

"This is only the beginning," Kakashi warned. "The real training starts now."

Naruto straightened his shoulders, a new resolve hardening within him. "I'm ready."

As he followed Kakashi through the winding tunnels back toward the surface, Naruto felt something he hadn't experienced in years: purpose. Not the hand-me-down purpose of being the Hokage's son, not the borrowed importance of being the non-prophesied sibling.

His own path. His own strength. His own shadow to cast.

Behind him, the ANBU training grounds fell silent, waiting for the return of their newest recruit—a boy stepping willingly into darkness to find his light.

# Shadow of the Fox: The Forgotten Heir

## Chapter 3: Masks of Identity

Blood splattered across the stone floor as Naruto crashed into the wall. The metallic taste flooded his mouth, but he didn't have time to spit before rolling right—barely avoiding the tantō blade that embedded itself in the concrete where his head had been a heartbeat earlier.

"Too slow!" barked his attacker, a lithe ANBU operative with a mongoose mask. "If I wanted to kill you, you'd be cooling on the floor."

Naruto launched himself upward, flipping mid-air to land in a defensive crouch. Sweat dripped into his eyes, stinging, but he didn't dare blink. Three weeks into his ANBU training, and each session still left him battered, bruised, and gasping for breath.

"Again," commanded the voice from the observation platform above.

Mongoose didn't wait for Naruto to acknowledge the order. The operative vanished in a blur of motion, reappearing behind Naruto with blade already swinging. This time, Naruto was ready. He twisted his body at an impossible angle—a maneuver that would have torn a muscle three weeks ago but now felt almost natural—and caught Mongoose's wrist.

The operative's eyes widened behind the mask slits as Naruto executed a perfect counterstrike, his palm stopping a hair's breadth from Mongoose's throat.

"Better," came the approving voice from above. Kakashi stepped into the light, dog mask pushed aside to reveal his usual half-covered face. "You're learning to anticipate rather than merely react."

Naruto released Mongoose and stepped back, chest heaving. The underground training facility—a cavernous space beneath Konoha accessible only through hidden ANBU passages—echoed with his labored breathing.

"Not good enough," Naruto gasped, wiping blood from his split lip. "I still took the first hit."

"Against an opponent with five years of ANBU field experience," Kakashi pointed out. He jumped down from the platform, landing silently beside them. "Most genin wouldn't have survived the first five seconds."

Mongoose gave a curt nod of agreement before bowing to both of them and vanishing through one of the facility's many hidden exits.

"Today marks the end of your basic combat assessment." Kakashi pulled a scroll from his flak jacket. "Starting tomorrow, you begin specialized training."

Naruto straightened, fatigue momentarily forgotten. "Specialized?"

"ANBU operatives aren't just elite fighters. We're specialists." Kakashi unfurled the scroll, revealing a training schedule dense with notations. "Assassination techniques. Intelligence gathering. Stealth operations. Trauma resistance."

The clinical terms sent a chill down Naruto's spine. This wasn't the glory-filled training his father had promised so many times—this was something darker, harder, more pragmatic.

"You'll need more than just me for this phase," Kakashi continued. "I've selected three additional trainers. Each is a master in their field."

The door across the chamber slid open, and three masked figures entered. Even by ANBU standards, they moved with exceptional grace—predators among predators.

"Yugao Uzuki," Kakashi indicated the tallest figure, who wore a cat mask. She pulled it aside to reveal striking purple hair and sharp, assessing eyes. "Konoha's foremost sword specialist."

She nodded once at Naruto. "I've reviewed your kenjutsu aptitude tests. We have work to do."

"Tenzō," Kakashi continued as a shinobi with a stylized face mask stepped forward. "His unique abilities make him particularly valuable for containment scenarios."

Unlike Yugao, Tenzō kept his mask in place, offering only a slight bow.

"And Owl." The third figure remained motionless, their mask a perfect representation of the nocturnal predator, with oversized eye slits that revealed nothing of the face beneath. "Our tactical specialist."

Owl's voice, when it came, was deliberately modulated—impossible to determine age or gender. "I'll be evaluating your strategic thinking and psychological resilience."

Naruto swallowed hard. The quiet authority emanating from these elite operatives made even his father's presence seem somehow less imposing.

"Your training begins at 0400 tomorrow," Kakashi said, rolling up the scroll. "Until then, maintain your cover. Your genin team has a C-rank mission in the morning—something about escorting a merchant to the border."

"I remember," Naruto confirmed, though in truth, Team 7's routine assignments had begun to feel increasingly trivial compared to his nighttime activities.

As if reading his thoughts, Yugao stepped forward. "Don't underestimate the importance of your public role. The most effective operatives are those who seem the least remarkable."

"Your family name makes that challenging," Owl observed, their voice revealing nothing. "But perhaps being overshadowed has its advantages."

The remark stung more than Naruto wanted to admit, but he kept his expression neutral—another skill he'd been honing these past weeks.

"I'll see you all tomorrow," he said, bowing formally to his new instructors.

As he turned to leave, Tenzō finally spoke, his voice surprisingly gentle behind the harsh mask. "One more thing, Trainee Fox. Sleep tonight. You won't get much chance for the next seventy-two hours."

The Namikaze dining table gleamed under soft lamplight, laden with dishes that showcased Kushina's Uzumaki heritage—spicy seafood ramen, salt-broiled saury, and red bean soup that steamed invitingly in ceramic bowls. The rich, savory scents filled the room, mingling with the subtle fragrance of fresh-cut flowers arranged in the center of the table.

Naruto slipped into his seat quietly, nodding at the family cook who smiled warmly at him. At least someone noticed when he arrived.

"And then," Menma was saying, gesturing wildly with his chopsticks, "Pervy Sage had me channel the Yang chakra into this huge water balloon, but instead of just popping it, I made it explode so hard it knocked over all his 'research' notebooks!"

Kushina burst into laughter while Minato shook his head, smiling indulgently. "That serves him right for taking you anywhere near the hot springs while he's 'gathering material' for those books of his."

"Dad," Mito piped up, twirling a strand of red hair around her finger, "can I try the water balloon exercise too? I bet I could make it pop even bigger than Menma."

"Always a competition with you two," Kushina said fondly, reaching over to ruffle Mito's hair. "But you know your Yin chakra works differently. We'll need to modify the technique."

"I could help with that," Minato offered, his expression brightening with the puzzle. "Jiraiya and I could develop a variant that works with Yin release."

The family continued discussing training possibilities, completely absorbed in the twins' progress. None of them had acknowledged Naruto's arrival, despite him sitting directly across from his father.

Naruto quietly filled his bowl with ramen, the familiar ritual bringing an odd comfort. Three weeks of relentless ANBU training had pushed his body to limits he hadn't known existed. New calluses hardened his palms. Fresh bruises blossomed beneath his civilian clothes. His chakra pathways burned from constant use. Yet somehow, the physical pain was easier to bear than this—this polite invisibility at his own family table.

"—don't you think, Naruto?"

The sound of his name jerked Naruto from his thoughts. His mother was looking at him expectantly, her violet eyes focused on him for what felt like the first time in months.

"Sorry," he said, realizing he'd missed whatever question she'd asked. "I was thinking about something else."

Kushina's brow furrowed slightly. "I asked if you'd heard about the chūnin exams. They're being held in Konoha this year. Your father thinks your team might be ready to participate."

Naruto's chopsticks paused halfway to his mouth. "Our team? When were you going to tell me?"

"I'm telling you now," Minato said, looking slightly puzzled at Naruto's reaction. "It's still three months away—plenty of time to prepare. Your team leader will make the final recommendation, of course."

"Our substitute leader," Naruto corrected automatically. "We still don't have a permanent jōnin assigned."

"Right, right." Minato waved his hand dismissively. "I'm working on that. It's just with the exam preparations and the twins' training schedule, finding the right jōnin has been challenging."

Of course it has, Naruto thought bitterly. Any jōnin worth their rank would prefer training the Nine-Tails jinchūriki rather than a regular genin team, even if that team included the Hokage's eldest son.

"I've been training on my own," Naruto said, curious if anyone had noticed his nightly absences or the changes in his physique.

"That's nice, dear," Kushina said absently, already turning back to Mito. "Now, about that chakra control exercise..."

Naruto ate mechanically, the ramen's flavor lost on his tongue. Three weeks ago, being ignored at the dinner table had filled him with resentment. Now, it filled him with relief. The less attention paid to him, the easier it would be to maintain his double life.

"Can I be excused?" he asked during a lull in conversation. "I've got an early mission tomorrow."

Minato glanced up, mild surprise crossing his features as if just remembering Naruto was there. "Of course. What's the mission?"

"Merchant escort to the eastern border," Naruto replied, rising from his chair. "C-rank. Standard protection detail."

"Be careful," his father said automatically, before immediately returning to his conversation with the twins about advanced sealing techniques.

Naruto slipped from the dining room like a shadow, neither his departure nor the soft click of the door registering with his family. He paused in the hallway, listening to the continued flow of conversation, the laughter, the engagement that hadn't faltered for even a moment with his exit.

In the polished surface of a decorative mirror, his reflection stared back at him—blue eyes hardening with acceptance rather than pain. This disconnection that had once wounded him so deeply was becoming an asset. The perfect cover for his new path.

He turned away from the mirror and headed to his room. He had four hours to sleep before meeting Yugao for his first sword training session, and Tenzō's warning echoed in his mind. Whatever was coming tomorrow would test him in ways even these past weeks hadn't prepared him for.

As he passed the family shrine in the hallway, he paused, his attention caught by something he'd walked past a thousand times before—a small ceremonial container placed behind larger, more ornate offerings. Unlike the elaborate shrines dedicated to ancestors or the memorials to the Nine-Tails' defeat, this modest vessel sat almost forgotten, its surface dulled with age.

Naruto reached for it, drawn by an impulse he couldn't explain. As his fingers brushed the container's surface, a jolt of energy surged through him—hot and wild, like touching a live wire. He jerked back, heart pounding.

The container hadn't moved, hadn't changed, yet suddenly seemed to pulse with hidden significance.

"It wasn't meant for you to find."

Naruto whirled to find his mother standing in the hallway, her expression unreadable in the dim light.

"What is it?" he asked, rubbing his tingling fingertips.

Kushina approached slowly, her gaze fixed on the small container. "A precaution. When we sealed the Nine-Tails into Menma and Mito, its chakra was divided—Yang to Menma, Yin to Mito. But chakra is never perfectly divisible."

She reached past him and lifted the container, her movements reverent and precise. "A small portion—too small to be meaningful—had to go somewhere. Your father contained it in this vessel."

Understanding dawned like ice water down Naruto's spine. "It's inside there? Fox chakra?"

"Was," Kushina corrected softly. "When you were five, you found this vessel and opened it. The chakra fragment was too small to cause harm, but it bonded with you before we could stop it."

Naruto stared at her, stunned. "I have Nine-Tails chakra? Why didn't you ever tell me?"

"Because it doesn't matter," Kushina said, replacing the container on the shrine. "The fragment is too small to be useful—barely enough to register. Not like the twins, who each have enough to fulfill the prophecy."

"Does it... do anything?" Naruto pressed, mind racing with implications.

Kushina shrugged lightly. "Your sense of smell is sharper than average. Your stamina is good. But nothing like the power your siblings can access." She turned to him, finally meeting his eyes directly. "We didn't tell you because we didn't want you feeling... left out."

The irony of that statement hung between them, too profound for Naruto to even acknowledge. Instead, he simply nodded. "I understand. Thank you for explaining."

Kushina studied him for a moment, a flicker of something—guilt? concern?—crossing her features. "You've been quiet lately. Is everything alright with your team?"

Now she noticed? After weeks of him practically disappearing from family life?

"Everything's fine," he said, mastering his expression. "Just focused on improving."

She reached out as if to touch his cheek, then hesitated, her hand falling back to her side. "You know your father and I are proud of you, right? It's just with the prophecy and the twins' training..."

"I know," Naruto said, cutting off the familiar justification. "The village comes first. The prophecy comes first. I understand."

Before she could respond, Menma's voice called from the dining room, asking about dessert. Kushina's attention snapped away immediately, the moment of connection evaporating.

"We'll talk more later," she promised, already moving back toward the dining room.

Naruto didn't bother responding. There would be no "later." There never was.

But as he continued to his room, his fingertips still tingled with the memory of that surge of power. A fragment of the Nine-Tails. Too small to matter to them, perhaps, but to him? It might make all the difference.

---

Dawn hadn't yet broken when Naruto stumbled into the hidden ANBU medical facility, his body a constellation of fresh cuts and bruises. Yugao stood nearby, her cat mask pushed aside to reveal a satisfied expression.

"Impressive adaptation," she noted, wiping blood from her blade. "Most trainees can't hold a sword properly after the first six hours, let alone execute a counter-sequence."

"Is that what I was doing?" Naruto gasped, allowing the medic-nin to examine a particularly deep slash across his forearm. "Felt more like trying not to get skewered."

"Survival instinct is a powerful teacher," Yugao replied, a hint of dark humor in her voice. "Tomorrow we move to actual techniques now that you've developed the basic reflexes."

The medic-nin—masked like all ANBU support staff—finished closing Naruto's wound with a medical jutsu. "Your recovery rate is exceptional," she observed clinically. "The cellular regeneration resembles—"

"A jinchūriki's," Naruto finished quietly. "I know."

Yugao's eyes narrowed with interest. "You have fox chakra?"

"A fragment," Naruto confirmed, flexing his healed arm experimentally. "Too small to be useful, according to my mother. Just enough to heal paper cuts faster than normal."

"And enhance sensory perception," added another voice as Tenzō entered the room. He'd removed his mask, revealing surprisingly gentle features that contrasted with his imposing ANBU persona. "I wondered how you detected my presence during your evasion assessment. Even experienced jōnin miss those particular chakra suppression techniques."

Naruto shrugged uncomfortably. "I just... smell things. Hear things. It's not special."

"On the contrary," Tenzō countered, approaching with focused interest. "In our line of work, enhanced senses are invaluable. Particularly when tracking targets or detecting ambushes."

"Which makes this morning's exercise particularly relevant," announced Owl, materializing from the shadows with characteristic abruptness. Even in the secure facility, Owl maintained full mask protocol. "Sensory identification training. The ability to distinguish individual chakra signatures at range."

Naruto straightened despite his exhaustion. Kakashi had warned him that ANBU training would be relentless—no breaks, no coddling, no concessions to normal human limitations.

"I thought I was scheduled for infiltration tactics," he said, consulting his mental calendar.

"Plans change," Owl replied flatly. "Adaptability is survival."

Tenzō offered Naruto a canteen of water and what might have been a sympathetic look. "Drink. Eat this." He pressed a food pill into Naruto's palm. "We begin in five minutes."

As the instructors stepped away to confer, Naruto swallowed the bitter pill, feeling its artificial chakra surge through his depleted system. Seventy-two hours of continuous training—sword techniques with Yugao, sensory development with Owl, infiltration with Tenzō, and psychological conditioning with Kakashi.

All while maintaining his regular genin duties and family appearances.

The challenge would have seemed impossible three weeks ago. Now, it just felt like the next necessary step.

"Ready," he called, rising to his feet as the temporary energy infusion took effect.

Owl turned, mask betraying nothing. "Then follow. And remember—in ANBU, limits exist only in the mind."

---

Moonlight filtered through ancient trees, casting dappled silver patterns across a forest clearing that few in Konoha knew existed. Thirteen masked ANBU operatives stood in perfect formation around a stone altar, their presence so still they might have been carved from the darkness itself.

Naruto knelt at the center, head bowed, body trembling with exhaustion. Six weeks of training had transformed him—hardened his muscles, sharpened his reflexes, and honed his mind into a weapon as deadly as any blade. But nothing had prepared him for the ritual that awaited.

Bear, the ANBU commander, approached with measured steps. In his hands he carried a wooden box, its surface inscribed with seals so ancient their meaning had been lost to all but a select few.

"Trainee," Bear intoned, his deep voice echoing in the clearing. "You have completed the first phase of ANBU preparation. You have been tested in body, mind, and spirit. You have been found worthy."

The words washed over Naruto like a physical force. Worthy. How long had he craved that recognition? How many years had he spent trying to prove himself deserving of attention, of acknowledgment?

"ANBU exists in shadow," Bear continued, setting the box on the altar before Naruto. "We are the unseen shield of Konoha. We protect without glory. We serve without recognition. We die without memory."

Around the clearing, the assembled operatives touched their masks in unified salute.

"To become one of us is to surrender your individual identity in service to the village." Bear opened the box, revealing a porcelain mask nestled on black cloth. "From this night forward, if you accept, you will exist in two worlds—your public face, and your ANBU truth."

Naruto's gaze fixed on the mask. Unlike the stylized animal visages worn by the others, this one was unmistakably vulpine—a fox with sharp ears and slitted eyes, painted with red markings that swept back from the eye holes like tears of blood.

"Fox," Bear named it, lifting the mask from its case. "The trickster. The survivor. The shadow that moves unseen between worlds."

A murmur rippled through the assembled ANBU—the most emotion Naruto had ever witnessed from the elite corps. The symbolism wasn't lost on anyone present. The son of the Hokage, brother to the Nine-Tails jinchūriki, taking the fox as his ANBU identity.

"Do you accept this mask, this name, this life?" Bear asked formally. "Once taken, it cannot be returned."

Naruto raised his head, meeting the commander's gaze through the mask slits. In that moment, he saw his life diverge into two distinct paths—the neglected son continuing to chase acknowledgment that might never come, or the shadow operative forging a new identity beyond his family's legacy.

"I accept," he said, his voice unwavering.

Bear nodded once, then placed the mask in Naruto's hands. The porcelain felt cool against his skin, yet seemed to pulse with subtle energy—as if the mask itself were alive, waiting to bond with its new owner.

"Then rise, Fox, and join your brethren."

Naruto stood, holding the mask before him. With a single, decisive movement, he placed it over his face—and felt the world transform. Through the eye slits, the clearing appeared sharper, the moonlight brighter, the assembled ANBU more distinct.

From the shadows, Kakashi—Hound—stepped forward, carrying a ceramic cup filled with dark liquid.

"Blood of the covenant," Hound explained, offering the cup. "A binding seal that protects ANBU identities even under torture or genjutsu interrogation."

Naruto accepted the cup without hesitation. The liquid tasted of iron and bitter herbs, burning a path down his throat to settle like fire in his stomach. Almost immediately, he felt the seal taking effect—chakra pathways shifting to accommodate the new protection.

"The ritual is complete," Bear announced. "Operative Fox is received into ANBU under probationary status. Captain Hound will serve as his direct superior until full operational clearance is granted."

The ANBU formation shifted, creating an opening in their circle—a space for Naruto to join them. As he stepped into position, each operative touched a hand to his shoulder in silent welcome.

When Yugao—Cat—reached him, she leaned close to whisper: "The mask you wear outside ANBU is now your true disguise. Remember that."

As the moonlight ritual concluded and the operatives dispersed one by one, Naruto remained in the clearing, feeling the weight of the mask against his face. For the first time in years, he felt a sense of belonging that had nothing to do with his family name.

Here, in the shadows, he wasn't Naruto Namikaze, forgotten son of the Hokage. He wasn't the brother of prophesied saviors or the child whose birthday no one remembered.

He was Fox—a name he had earned rather than inherited.

As he finally turned to leave the sacred clearing, he caught his reflection in a small pool of water. The fox mask stared back at him, its painted features somehow more honest than the face he'd shown his family for years.

Behind the mask, Naruto smiled for the first time in weeks—a predator's smile, sharp and dangerous. Let his family have their prophecy and their power. Let them continue their important training and special techniques.

He had found his own path in the darkness they had left him to.

And darkness, he was discovering, suited him perfectly.

# Shadow of the Fox: The Forgotten Heir

## Chapter 4: First Blood

The moonlight cut like a blade through the forest canopy, carving silver paths across the ANBU briefing chamber. Naruto—no, Fox—stood with his back perfectly straight, mask in place, breath controlled to near-imperceptible. Two months of relentless training had transformed him; gone was the slouching genin, replaced by a predator wrapped in human skin.

Bear paced before the assembled squad, his footfalls making no sound on the stone floor. The commander's mask caught the fractured light, turning his expressionless porcelain face into something almost demonic.

"Intelligence indicates Sound Village infiltration at the eastern border of Fire Country," Bear's voice sliced through the silence. "Operatives Fox and Wood will conduct surveillance and gather actionable intelligence regarding the target's objectives."

Naruto's pulse quickened beneath his mask. First mission. Real mission. The weight of the porcelain against his face suddenly felt heavier.

"This is a reconnaissance operation only," Bear continued, unfurling a map across the stone table. His finger traced a path through the borderlands. "No engagement unless absolutely necessary. Your primary objective is information gathering."

From the corner of the chamber, Kakashi—Hound in his ANBU persona—stepped forward. "Fox is still on probationary status. Wood will maintain operational command."

Bear nodded once, the gesture sharp and decisive. "Departure in thirty minutes. Dismissed."

The small assembly dissolved, operatives vanishing into shadows with practiced efficiency. Only Tenzō remained, his Wood mask tilted slightly toward Naruto.

"Ready for field conditions, Fox?" Tenzō asked, his voice carrying the particular flatness that all ANBU adopted on duty.

"Yes, sir." The response came automatically now, the respectful formality of ANBU hierarchy ingrained through weeks of brutal conditioning.

"Good." Tenzō's mask revealed nothing, but something in his voice softened imperceptibly. "First field missions are... memorable. Follow protocol, control your emotions, and we'll complete this without complications."

Control your emotions. The cornerstone of ANBU training. Naruto had spent weeks in Owl's psychological conditioning sessions, learning to partition his mind, to separate feeling from action, to execute without hesitation.

"Understood." Naruto checked his equipment with practiced efficiency—kunai, wire, soldier pills, specialized ANBU tools nestled in concealed pockets. Each item exactly where muscle memory expected it.

Tenzō watched his preparations with the stillness of a statue. "Your brother's birthday celebration begins tomorrow night, doesn't it?"

The question caught Naruto off-guard, his hands pausing momentarily over his equipment. "How did you—"

"Background intelligence is part of mission preparation," Tenzō replied, matter-of-factly. "The village will be distracted. Security patterns altered to accommodate the celebration."

Understanding dawned. "You think that's why Sound is moving now."

"It's a reasonable speculation." Tenzō's fingers tapped once against his thigh—a rare display of agitation from the typically stoic operative. "The Hokage's children would be valuable targets for any enemy village, particularly jinchūriki."

The thought hadn't occurred to Naruto. His siblings, for all their special training and prophecy, were still just children—vulnerable despite their power. Something protective and fierce surged beneath his calculated ANBU calm.

"Then we should move," he said, securing his last weapon. "The sooner we identify the threat, the sooner we can neutralize it."

Tenzō's mask tilted, studying him. "Remember, Fox—reconnaissance only. Your emotions regarding family cannot factor into operational decisions."

Naruto secured his mask, feeling the familiar seal of identity protection activate with a tingle of chakra across his face. "I don't have family when I wear this mask," he replied, the words feeling like truth and lie simultaneously. "I only have the mission."

---

The eastern border of Fire Country sprawled beneath them, a patchwork of forest and farmland washed pale under the waxing moon. Perched in the highest branches of an ancient oak, Naruto and Tenzō had maintained surveillance position for six hours, motionless except for the occasional hand signal.

Through specialized ANBU binoculars, Naruto tracked the movements in the small border town below. Mostly civilians—farmers, merchants, the occasional traveler—but his enhanced senses had already identified three individuals with suppressed chakra signatures moving through the market district.

"Two more at the northern checkpoint," he whispered, the words barely disturbing the air between them. "Chakra patterns consistent with Sound techniques."

Tenzō's acknowledgment came as a nearly imperceptible tap of finger against branch. For hours they'd been building a pattern of the infiltrators' movements, tracking rotations and communications.

"They're too organized for a simple border probe," Tenzō murmured eventually. "Methodical sweep patterns. They're searching for something specific."

The moon climbed higher, casting sharper shadows across the landscape. In the distance, lights from Konoha glowed against the night sky—the village preparing for tomorrow's festivities. The Hokage's son turning ten merited considerable celebration, particularly when that son carried half the Nine-Tails' power.

A flicker of movement at the edge of town caught Naruto's attention. Two figures converging behind a storage building, chakra signatures muted but detectable to his enhanced senses.

"Meeting in progress," he signaled to Tenzō. "Northeast quadrant."

Tenzō nodded once. "Maintain position. I'll move for audio intelligence."

With practiced silence, Tenzō merged with the tree trunk, his Wood Release allowing him to travel through the forest's connected root system. The jutsu never failed to impress Naruto, despite his months of working alongside the unique operative.

Alone in the observation post, Naruto maintained visual surveillance, tracking the positions of every identified Sound operative through the binoculars. Six infiltrators confirmed so far—more than expected for a simple reconnaissance mission, but not enough for a full-scale operation.

Twenty minutes passed before Tenzō re-emerged from the trunk beside him, his mask hiding whatever he'd discovered. But the rigid set of his shoulders told Naruto everything.

"Report," Naruto prompted, keeping his voice level despite the tension radiating from his partner.

"It's a capture operation," Tenzō confirmed, his voice tight beneath the professional flatness. "Timed for tomorrow night during the celebration. Two targets. Extraction plan already established."

Ice formed in Naruto's veins. "The targets?"

Tenzō's hesitation lasted only a fraction of a second. "Your siblings, Fox. They're here for the jinchūriki."

The world narrowed to pinpoint focus, sounds suddenly sharper, scents more distinct, as the fox chakra fragment resonated with his heightened emotional state. Naruto forced his breathing to remain steady, applying Owl's intensive conditioning.

"Command decision?" he asked, the question stripped of all personal investment.

"Protocol dictates immediate return to Konoha with intelligence," Tenzō replied. "Village security can intercept the threat."

"Timeframe?"

"Their operation commences at 2200 hours tomorrow. They have advance operatives already positioned in Konoha." Tenzō's mask turned toward the distant village lights. "Including someone with inside access to the celebration security plans."

A traitor in Konoha. The implications cascaded through Naruto's tactical assessment. If the Sound operatives had infiltrated village security, standard reporting channels might compromise the response.

"We should eliminate the threat now," Naruto said, the words cold and precise. "Neutralize the field operatives before they can coordinate with their inside assets."

"Negative," Tenzō countered immediately. "We have confirmed intelligence but not operational clearance. Protocol requires—"

A pulse of chakra from the village interrupted him—a distinctive flare pattern used exclusively by ANBU for emergency signals. Three short bursts, followed by two long pulses.

Imminent threat. Hokage family. Advance to engage.

Tenzō straightened, all hesitation vanishing. "Signal override from command. The timeline has accelerated."

Adrenaline surged through Naruto's system, instantly channeled into focused action. "Simultaneous or sequential neutralization?"

"Split and converge," Tenzō decided, the ANBU captain emerging fully in his posture and tone. "You take the two northern targets. I'll sweep the southern group. Zero witnesses."

Naruto was already moving, body responding to weeks of drilled procedures. "Rendezvous at checkpoint alpha upon completion."

"Fox." Tenzō's voice halted him momentarily. "This is no longer reconnaissance. Confirm operational status."

The implication hung between them. This would not be a training exercise or a simulation. This was combat deployment with lethal authorization.

"Status confirmed," Naruto replied, the mask hiding whatever emotions might have flickered across his face. "Proceeding to engage."

---

The first target never saw him coming.

Naruto descended from the night sky like his namesake, silent and deadly. The Sound operative—a lanky man with bandaged arms and a respirator mask—had just enough time to register surprise before Naruto's tantō sliced through his carotid artery in a precise strike Yugao had drilled into him hundreds of times.

Hot blood sprayed across Naruto's mask and gloved hands, but his strike continued smoothly, severing the spinal cord to ensure immediate neutralization. The body crumpled without a sound, dead before it hit the ground.

First kill. The thought registered distantly, clinically, as Naruto activated the quick-decomposition jutsu ANBU used to eliminate evidence. The body would be unrecognizable within hours, reduced to base elements that would fertilize the forest floor.

No time to dwell on the psychological milestone. The second target was already moving, headed toward the village with unnatural speed that confirmed shinobi status.

Naruto pursued through the treetops, his body flowing from branch to branch with liquid grace. The training that had seemed so brutal, so excessive, now translated into flawless execution. Each movement conserved energy, each trajectory optimized for silent pursuit.

The Sound operative paused at a stream crossing, hands forming seals for what appeared to be a communication jutsu. Naruto didn't hesitate. Three senbon flew from his fingers, striking pressure points that temporarily paralyzed the target's vocal cords and dominant arm.

The man whirled, eyes widening at the fox mask materializing from the darkness. He reached for a weapon with his non-dominant hand, but Naruto was already inside his guard, ANBU-issue blade piercing his heart with mechanical precision.

Second kill. Again, the thought registered without emotion, partitioned neatly behind the psychological barriers Owl had constructed during training.

The operative's eyes locked with his as life drained from them—confused, pained, and finally vacant. Naruto lowered the body silently to the forest floor, activated the decomposition jutsu, and turned toward the village without pause.

The emergency signal meant the timeline had collapsed. Sound was already moving on Konoha, which meant the advance team had either been detected or had initiated their operation early.

Either way, his siblings were in immediate danger.

Konoha's streets teemed with pre-celebration activity despite the late hour. Vendors erected stalls for tomorrow's festival, lanterns and decorations transforming the village into a riot of color that would only fully bloom at daybreak.

Naruto moved above it all, traveling across rooftops with his chakra signature completely suppressed. The fox mask had been temporarily sealed into a scroll—in-village ANBU operations required different protocols to avoid civilian panic.

He navigated by memory and instinct toward the Namikaze compound. The emergency signal had specified a threat to the Hokage's family, but without specific intelligence, Naruto couldn't determine exactly where his siblings might be.

A flare of familiar chakra drew his attention westward. Menma. His brother's energy signature had grown increasingly distinctive as the Nine-Tails' Yang chakra developed within him. Right now, that signature pulsed with exertion—combat exertion.

Naruto changed direction instantly, pushing chakra into his legs to accelerate across the village skyline. The residential district blurred beneath him as he covered ground with preternatural speed.

The scene that materialized before him froze his blood.

Menma stood in a small training ground, surrounded by three Sound operatives. The boy's clothing was torn, a gash across his forehead leaking blood down his face, but his hands maintained a defensive seal as crimson chakra flickered erratically around him.

"—don't understand what you're dealing with," Menma was saying, his voice strained but defiant. "My father will—"

"Your father is occupied with a diversion on the eastern wall," one of the Sound nin replied, advancing slowly. "By the time he realizes this isn't a border incursion, you'll be long gone from Konoha."

Another operative circled behind the boy. "Lord Orochimaru is most interested in examining that seal of yours. The Yang half of the Nine-Tails... such potential."

Naruto assessed the situation in milliseconds. Three jōnin-level targets. Menma exhausted but conscious. No village security in immediate vicinity—they'd chosen their moment perfectly, with ANBU and regular forces redirected by whatever diversion they'd created.

Protocol dictated waiting for backup, maintaining surveillance until additional ANBU arrived.

Protocol hadn't accounted for the target being his little brother.

Decision made, Naruto unsealed his mask. The porcelain settled against his face like a second skin, the identity transformation immediate and complete. Fox responded with the deadly precision hundreds of hours of training had instilled, launching four poisoned senbon in a spread pattern that caught the closest Sound operative through the neck.

The man dropped without a sound, dead before his companions registered the attack.

The remaining two operatives whirled, hands flashing through defensive seals. "ANBU!" one hissed. "Take the boy now!"

Naruto materialized between them and Menma, tantō gleaming in the moonlight. The Fox mask revealed nothing of the fury churning beneath his controlled exterior.

"Konoha ANBU," he announced flatly, voice modulators in the mask distorting his natural tone. "Surrender or be eliminated."

Their response came in the form of synchronized attack jutsu—a sound wave technique that shattered the ground beneath his feet. Naruto leapt skyward, feeling the destructive vibrations pass harmlessly beneath him as his hands formed seals for a counterattack.

"Water Style: Severing Wave!"

A pressurized blade of water sliced through the air where one operative had stood a moment before. The man dodged, but not quickly enough to avoid a partial strike that severed his arm at the elbow. Blood fountained from the wound as he screamed, the sound cutting through the quiet night.

The remaining operative seized the moment of distraction, lunging toward Menma with a capture seal glowing in his palm. "The mission must succeed!"

Time slowed to crystal clarity. Naruto calculated trajectories, distances, response options—all in the fraction of a second it took to pivot toward his brother.

Menma stood frozen, eyes wide with exhaustion and fear, the flickering fox chakra around him sputtering as his reserves depleted. In that instant, he wasn't the golden child of prophecy or the favored son—just a scared nine-year-old boy about to be kidnapped by enemies who would tear him apart to get at what he contained.

Naruto moved.

His body flickered between dimensions in a technique he'd reverse-engineered from watching his father—not the full Flying Thunder God, but a bastardized version that allowed for short-range instantaneous movement. One moment he stood three meters away; the next, his tantō plunged through the Sound operative's throat, the blade continuing through until it emerged crimson from the back of the man's neck.

The operative's eyes bulged with shock, the capture seal fading as his life essence poured down the front of his uniform. His hands clutched desperately at Naruto's wrist, fingernails scrabbling against ANBU armor.

"Ko... no... ha..." Blood bubbled from his lips, spattering the pristine surface of Naruto's mask. His eyes fixed on the expressionless fox visage, perhaps searching for mercy or humanity in its painted features. He found none.

Naruto twisted the blade with clinical precision, severing the spinal cord. The body went limp, sliding off his weapon to crumple at his feet.

Silence descended upon the training ground, broken only by Menma's ragged breathing and the pained moans of the wounded operative clutching his severed arm.

Naruto turned toward his brother, who stared back with a mixture of awe and terror. Blood streaked the boy's face, mingling with tears he was too proud to acknowledge.

"Are you Konoha ANBU?" Menma asked, his voice small but struggling to maintain composure.

Naruto nodded once, maintaining operational protocol despite every instinct screaming to comfort his sibling. "You're safe now."

The wounded Sound operative chose that moment to stagger to his feet, desperation overriding pain as he formed one-handed seals. "Die, Konoha scum!"

The attack never materialized. Naruto's thrown kunai pierced the man's eye socket with mathematical precision, the blade driving deep into his brain. He collapsed without another sound, dead before his body settled into the dirt.

Menma swayed on his feet, chakra exhaustion finally claiming him as the adrenaline ebbed. "My sister..." he mumbled, eyes rolling back as he pitched forward.

Naruto caught him before he hit the ground, cradling his unconscious brother with a gentleness at odds with the carnage surrounding them. Through the mask, he inhaled Menma's scent—blood and sweat overlaying the familiar notes of home and family.

My sister. Mito. Was she also targeted? Naruto's mind raced through scenarios, but before he could form a response plan, another ANBU operative landed silently beside him.

"Fox." Kakashi's Hound mask tilted toward the bodies scattered across the training ground. "Situation?"

"Three hostiles neutralized," Naruto reported, voice steady despite the storm of emotions beneath. "Target secure but requires medical attention. Second target status unknown."

"The girl is safe," Kakashi confirmed. "Lord Fourth intercepted the team sent for her. The diversion has been contained." His mask turned toward Menma's unconscious form. "You did well, Fox."

Something tight in Naruto's chest eased slightly. Mito was safe. The immediate threat neutralized.

"Cleanup protocol?" he asked, still holding his brother's limp form.

"I'll handle the scene," Kakashi replied. "Get the boy to the hospital. Drop him at the emergency entrance and maintain your cover."

Naruto hesitated, looking down at Menma's face. Blood matted the boy's black and red hair, making him look younger and more vulnerable than his nearly ten years.

"He saw my mask," Naruto said quietly. "He might remember."

"I doubt he'll recall details through the trauma and chakra exhaustion," Kakashi responded. "But if necessary, memory modification can be arranged." The senior ANBU placed a hand briefly on Naruto's shoulder. "You saved his life, Fox. Remember that."

Naruto nodded once, then gathered his brother more securely in his arms. "Proceeding to medical facility."

As he leapt back into the night, carrying his unconscious sibling across the rooftops of Konoha, Naruto felt the partitioned emotions of his mind threatening to breach their carefully constructed walls. Beneath the mask, beneath the ANBU conditioning, beneath the calculated precision of his actions, something primal and protective howled in satisfaction.

Mine to protect. My family. My blood.

The fox fragment inside him resonated with this territorial instinct, chakra humming beneath his skin as he raced toward the hospital.

The emergency entrance to Konoha Hospital stood brightly lit against the darkness, medical staff visible through glass doors as they moved efficiently through their nighttime routines. Naruto landed silently in the shadows across the street, still holding Menma's unconscious form.

"I've got you, little brother," he whispered, allowing himself one moment of unveiled emotion before duty reasserted itself.

With practiced stealth, he approached the entrance, Menma cradled in his arms. Twenty meters from the doors, he carefully set the boy on the ground, positioning him where he would be immediately visible to anyone looking outside.

Naruto pressed two fingers to Menma's neck, confirming his pulse remained strong and steady. The head wound had mostly stopped bleeding—another benefit of being a jinchūriki, even a partial one. He would recover quickly with proper care.

After one final check of his brother's condition, Naruto backed away into the shadows. From a safe distance, he formed a single hand seal, creating a small pulse of chakra that triggered the hospital's perimeter sensors.

Immediately, the doors burst open as medical personnel rushed outside, spotting Menma's crumpled form on the pavement. Two medic-nin hurried to the boy's side, their hands already glowing with diagnostic jutsu.

"It's the Hokage's son!" one called urgently. "Get a trauma team out here now!"

Within seconds, Menma was surrounded by medical staff, carefully lifted onto a stretcher and whisked inside the building. Emergency protocols would alert his parents immediately—the Hokage's child injured outside the hospital warranted highest priority response.

Naruto watched until the doors closed behind them, then melted back into the darkness. His mission was complete. His brother was safe. The operational parameters had been satisfied.

So why did his hands still tremble beneath their blood-stained gloves?

Dawn painted the village in gentle gold as Naruto slipped through his bedroom window, ANBU gear sealed away, wearing the simple training clothes that maintained his cover. He'd spent hours helping Tenzō and Kakashi eliminate all evidence of the Sound operation, filing reports in the secure ANBU facility deep beneath Konoha, debriefing with Bear on the mission outcome.

No one had questioned his actions. No one had remarked on the fact that his first field operation had resulted in four confirmed kills, all to protect his brother. ANBU didn't acknowledge such personal connections—they didn't exist in that world of masks and shadows.

Exhaustion pulled at his limbs as he headed for the bathroom, desperate to wash away the memory of blood that still clung to him despite having already cleaned up at the ANBU facility. His parents wouldn't be home yet—they'd be at the hospital with Menma, waiting for him to regain consciousness.

The sound of voices from the kitchen froze him mid-step.

"—most extraordinary thing," his father was saying, voice carrying clearly through the quiet house. "To fight off three jōnin-level Sound operatives at his age! The medical team says he has multiple defensive wounds consistent with prolonged engagement."

"My baby," Kushina's voice trembled with a mixture of pride and lingering fear. "When I think what could have happened..."

"But it didn't," Minato reassured her. "Our son protected himself until help arrived. The Nine-Tails chakra responded to his distress, giving him the strength to hold them off."

Naruto inched closer to the kitchen doorway, keeping himself concealed in the hallway shadows.

"The ANBU report indicates an operative intervened," Kushina noted. "But Menma must have weakened them significantly. Three elite Sound nin..."

"He's truly special," Minato agreed, pride evident in every syllable. "When he wakes, we should move forward with the advanced chakra training Jiraiya suggested. This incident proves he has the control and the courage to handle it."

"The celebration will need to be postponed," Kushina sighed. "But perhaps that's for the best. After he recovers, we can combine it with a recognition ceremony. The village should know what he accomplished."

Their voices continued, plans and pride intermingling as they discussed their extraordinary son who had supposedly fought off multiple jōnin attackers—a feat impossible for a genin, let alone an academy student, regardless of what power they contained.

Naruto backed away silently, continuing to the bathroom where he locked the door behind him. He turned the faucets to full blast, drowning out any sound that might escape as he stripped off his clothes and stepped under the scalding spray.

Pink-tinged water swirled around his feet—blood that had seeped through his gear, staining his skin beneath. He scrubbed mechanically, removing all traces of the night's activities from his body while his mind replayed the wet sound of his tantō piercing human flesh, the hot splash of arterial blood across his mask, the light fading from a stranger's eyes.

He had killed four people tonight. Had watched their lives end by his hand. Had made the choice to end those lives without hesitation or remorse.

And downstairs, his parents celebrated a victory that wasn't theirs to claim, attributing impossible feats to their favored son while the true protector washed blood from beneath his fingernails.

Something shifted inside Naruto in that moment—something fundamental and irreversible. The compartmentalized emotions of his ANBU training didn't dissolve; instead, they crystallized into something harder and more permanent. The hurt of being overlooked, of being forgotten, transformed into cold acceptance.

He turned his face up into the spray, letting the water mingle with whatever moisture might have escaped his eyes. This was the path he had chosen—shadow guardian, unseen protector, the blade in darkness that preserved the light others basked in.

Let them have their hero, he thought, watching the last traces of crimson disappear down the drain. Let them have their prophecy and their celebrations.

He had taken his first life tonight. Had made his first kill. Had crossed a threshold from which there was no return.

And he had done it for family that would never know, for a village that would never see, for a duty that would never be acknowledged.

He was ANBU now—truly, irrevocably. A shadow among shadows.

Fox.
