Itachi pulled the sleek black sedan to the curb, parking precisely where they had agreed to meet. He stepped out, his movements fluid and economical, and joined Sasuke and Sakura on the sidewalk. His dark eyes, so similar to his brother's yet somehow more calculating, studied Sasuke briefly before he spoke. "How exactly do you know Tsunade Senju?" he asked, voice low. "She specializes in Omegas, doesn't she?"
Sasuke exhaled slowly, pinching the bridge of his nose. He'd shared Naruto's situation with his brother, but had deliberately omitted Tsunade's involvement. Beside him, Sakura remained silent, her analytical gaze shifting between the brothers. "She's kept Naruto off the Registry and supplied his suppressants for years," Sasuke finally said, his voice low. "I was protecting her identity."
Itachi's dark eyes narrowed slightly. "This discussion isn't over," he said, voice cool but measured. "For now, though, I'm more interested in why Tsunade Senju specifically requested your presence. Let's hear what she has to say."
Tsunade's clinic crouched between a laundromat and an abandoned storefront, its weathered brick exterior and frosted windows offering nothing to distinguish it from the other forgettable buildings on this quiet street. A single, modestly lettered sign reading "T. Senju, Medical Services" hung beside the door—unassuming, easily overlooked, precisely as intended. Sasuke stood on the sidewalk, eyes narrowed against the afternoon glare, the persistent ache beneath his sternum throbbing in time with his heartbeat. Beside him, Itachi's posture shifted almost imperceptibly, his trained gaze cataloging exits, sightlines, and the carefully positioned cameras tucked beneath the eaves—security measures invisible to casual passersby but obvious to someone accustomed to designing them.
"Before we go in," Sakura said, reaching into her coat pocket, "you both need to take these."
She produced a slim metal case, its surface scratched from frequent use. Inside, neat rows of small white pills nestled in individual compartments. Sasuke eyed them with suspicion, the set of his jaw hardening.
"Suppressants," she explained, voice lowered despite the empty street. "Modified ones. The waiting room is filled with Omegas. Your Alpha pheromones would cause panic, especially in those who've had... bad experiences." Her fingers hovered over the pills, a practiced gesture suggesting she'd done this countless times before. "They're short-acting. Three hours at most."
Itachi reached forward without hesitation, plucking one from its compartment. "Standard protocol for sensitive operations," he said, answering Sasuke's unasked question before dry-swallowing the pill.
Sasuke's gaze flicked between the pill and Sakura's steady hand. Each moment spent here was another moment Naruto remained missing. His chest constricted at the thought, the now-familiar pain intensifying. He took the pill, forcing it down his throat without water.
"How long until it takes effect?" he asked, his voice rough with impatience.
"Two minutes, give or take," Sakura replied, "You'll feel nothing, but your scent signature will be temporarily masked." She slipped the case back into her pocket. "Tsunade formulated these herself. They're better than anything available through official channels."
They approached the door together, Sakura leading with a confidence that seemed at odds with the hesitant, flirtatious student persona Sasuke had known at Konoha. She pressed a small button beside the doorframe, and a barely audible buzz sounded from within. Three seconds passed, then a metallic click as the lock disengaged.
The waiting room beyond the threshold told a story no official medical establishment ever would. A dozen people sat in mismatched chairs arranged around the perimeter, most with heads down, shoulders hunched, as if the habit of making themselves smaller had become ingrained. A child of perhaps eleven leaned against an older woman whose arms wrapped protectively around thin shoulders. In the corner, a young man with a healing bruise beneath one eye stared blankly at a magazine without turning its pages. The air carried the antiseptic sharpness of a medical facility, but underneath lay something else—fear, resignation, hope—emotions with their own distinctive scent that no suppressant could fully mask.
Every head lifted when they entered, eyes immediately assessing the newcomers with the wary calculation of prey animals. Sasuke felt their collective gaze like a physical weight before it shifted away, returning to their individual worlds of quiet endurance once Sakura's familiar presence registered.
The receptionist—a middle-aged Beta woman with steel-gray hair and eyes that missed nothing—nodded once at Sakura, her gaze lingering on the Uchiha brothers with undisguised suspicion.
"They're with me," Sakura said, no explanation offered beyond those three words.
The woman pressed a button beneath her desk. A door to the right of the reception area unlocked.
"She's expecting you," the receptionist said, attention already returning to her computer screen.
Sakura pushed through the door first, revealing a corridor that made Sasuke immediately tense. This was no ordinary clinic hallway. Metal-reinforced doors punctuated the walls at strange, calculated distances, each featuring a glowing keypad that required more than mere knowledge to access. In the corners where wall met ceiling, small black domes housed watchful electronic eyes that followed their every step, their tiny red lights blinking in silent vigilance.
The corridor ended at a heavy wooden door, oddly antique against the high-tech security surrounding it. No keypad here—just a brass knob polished by countless hands. Sakura knocked three times, the sound sharp in the silence.
"Enter," called a voice from within—female, authoritative, brooking no argument.
Sakura pushed open the door. Amber light from a single desk lamp washed over an office where medical journals in foreign languages filled floor-to-ceiling shelves. Behind the framed certificates and diplomas, partially hidden maps revealed a global network of pins and coded notations. At its center: an imposing oak desk where Tsunade waited.
Tsunade looked up from her paperwork, amber eyes scanning from Sakura to Sasuke before locking onto Itachi. Her blonde hair pulled tightly back revealed a face all sharp angles. Surgeon's hands rested flat on the desk. Everything about her—posture, gaze, presence—commanded obedience without asking for it.
Guilt lanced through Sasuke's chest. He remembered standing before this woman once before, making a solemn vow to protect Naruto. Now he returned with that promise broken. Tsunade's amber eyes seemed to strip away his defenses, exposing his failure not just to her, but to Kakashi, to Iruka, and worst of all, to Naruto himself. The weight of obligation pressed down on him; he owed her honesty, just as he'd owed it to Naruto's parents when they showed up at the dorm.
Something flickered across Tsunade's face as she met Sasuke's gaze—recognition, perhaps, of the guilt he couldn't hide. She exhaled slowly, one manicured hand motioning toward the chairs opposite her desk. As he and Itachi settled into the worn leather seats, Sakura clicked the door shut behind them and took up position at Tsunade's shoulder, her stance suddenly formal. Sasuke's brow furrowed at this transformation, the pieces of Sakura's presence here refusing to align in his mind.
Tsunade's fingers steepled beneath her chin as she broke the silence. "I believe we both know why you're standing in my office, Sasuke." Her gaze shifted to the taller Uchiha beside him. "But I don't remember inviting him."
Sasuke's shoulders went rigid. Beside him, Itachi remained perfectly still, his dark eyes locked with Tsunade's in silent challenge. The moment stretched between them like a thread pulled taut. Finally, Tsunade broke the standoff, shifting her amber gaze back to Sasuke. "Tell me exactly what's happened to Naruto," she demanded.
Sasuke exhaled slowly, the weight of repetition settling on his shoulders. Each retelling carved the horror deeper into his memory, but Tsunade deserved the truth, and they needed allies. His voice remained steady as he recounted discovering the hidden laboratory beneath the college grounds, finding the flash drive containing Obito and Orochimaru's confession to his parents' murder, the surreal reunion with Itachi—and then returning to an empty dorm room where Naruto should have been waiting, but wasn't.
Tsunade remained motionless as Sasuke finished, her face a mask that revealed nothing. Then she rose with deliberate slowness, the leather of her chair sighing as she approached the map on the wall seemingly lost in thought. Her silhouette cut sharp against the fading light, shoulders squared beneath her white coat. When she finally turned, her amber eyes found his, unflinching.
"You couldn't have prevented this," she said, each word measured and precise. "None of us could."
Sasuke's jaw tightened, his lashes lowering as something threatened to break behind his carefully constructed facade.
"Naruto's fate was sealed the instant he set foot on that campus," Tsunade continued, her voice hardening. "We were all just pieces in their game."
Sasuke nodded mechanically, the gesture hollow. His hand drifted to his sternum where an ache had taken residence, pulsing in time with his guilt—a self-inflicted sentence he had no desire to appeal. Tsunade's gaze sharpened at the movement, but she offered no absolution as she reclaimed her seat behind the desk, the leather creaking beneath her weight.
Tsunade's chair creaked as she leaned forward. "Enough about what we couldn't prevent. Tell me what the Akatsuki is doing to recover my godson."
Itachi went perfectly still, only his eyes betraying surprise. "You are more knowledgeable then you let on."
"More thorough than you realize." Tsunade nodded to Sakura, who retrieved a manila folder from a locked cabinet. The folder landed on the desk between them with a soft thud. "Operation Storefront, June second. Your organization liberated five Omegas from a trafficking ring disguised as a convenience store." She slid the folder toward Itachi with one manicured finger. "Each survivor needed help, help only my organization could do."
Itachi's fingers traced the edge of the folder before he closed it with deliberate care. "You're part of the Omega Liberation Network." Not a question—a conclusion drawn from carefully assembled evidence. Sasuke glanced between them, brow furrowed, clearly unfamiliar with whatever underground movement they were discussing.
Tsunade leaned back, the leather chair sighing beneath her. A smile curved her lips, sharp as a scalpel. "Part of it?" She let the pause stretch between them. "I created it."
Itachi's eyes narrowed, the only visible change in his otherwise impassive face. "The identity of the Network's founder has remained hidden for over a decade. Yet you claim that title so casually."
"The circle of those who know my role just expanded from five to seven." Tsunade's fingers drummed once against the desk, her amber gaze unwavering. "Extraordinary times demand extraordinary disclosures."
Sasuke's patience snapped. He shot to his feet, hands braced on the edge of Tsunade's desk. "While you two trade secret-society credentials, Naruto is still missing. What exactly does any of this have to do with finding him?"
"Sit down," Tsunade and Itachi commanded in perfect unison, their voices carrying identical notes of authority.
The synchronized order only intensified the heat climbing up Sasuke's neck, but he lowered himself back into the chair, jaw clenched tight enough to crack teeth.
Tsunade's amber eyes shifted between the brothers. "The Akatsuki and OLN working together changes everything," she said, her voice dropping to a dangerous timbre as she leaned toward Itachi. "I'm putting the full weight of my network behind this. Whatever resources you require, consider them yours." Her knuckles whitened against the desk. "Finding Naruto isn't just a priority—it's non-negotiable. And don't forget, Itachi, your organization's debt to me remains unpaid."
Itachi's expression remained impassive. "Akatsuki has deployed our best intelligence assets to locate Orochimaru's facility. We're pursuing every lead available."
"Every lead?" Tsunade's laugh held no humor. "While you juggle what—three, four other operations simultaneously?" She leaned forward, amber eyes blazing with such intensity that Sasuke felt the temperature in the room drop. "I'm not asking, Itachi. Pull every agent, redirect every resource. Nothing else matters until Naruto is found."
Sasuke's eyes cut to Itachi, searching his brother's face for any flicker of truth to Tsunade's accusation. Were they truly holding back resources that could bring Naruto home? His fingers curled into fists against his thighs as heat crawled up his neck. He had extended Itachi a fragile trust, and now even that threatened to crumble. Yet beneath the anger came a sobering thought—whatever fraction of their network Akatsuki committed was infinitely more than what he could muster alone. The realization settled in his chest like a stone.
Itachi's expression remained unchanged, but his voice took on a razor's edge. "You're asking us to abandon active rescue operations where victims have hours—perhaps minutes—left to live." He leaned forward slightly. "Our intelligence suggests Orochimaru will keep Naruto alive. His value as a research subject ensures his survival, at least temporarily." Sasuke felt ice crystallizing in his veins at his brother's clinical assessment. Itachi's gaze softened almost imperceptibly. "Every available resource that won't compromise existing missions is already dedicated to finding him. I give you my word."
Tsunade's palm crashed against the mahogany desk, the sound like a gunshot in the quiet room. "Unacceptable," she hissed through clenched teeth.
"Explain something to me," Itachi said, his voice dangerously soft. "What makes this single Omega worth sacrificing hundreds of others?" His dark eyes never left Tsunade's. "What makes him more important then those with even less time?" Sasuke's fingers twitched with the urge to strike his brother, even as understanding twisted like a knife in his gut. The Akatsuki wouldn't abandon their other missions—not even for Naruto. A sharp pain bloomed beneath his sternum, and his hand flew to his chest.
Tsunade noticed, then this she sat back with a knowing look and looked at Itachi, "I think you will find that finding Naruto is the top priority."
Itachi didn't back down, "And why is that?"
Tsunade turned to Sasuke. "The chest pains." Sasuke's hand fell away from his sternum as if burned, heat crawling up his neck. "When did they start? A day? Half a day after Naruto left?" His eyes widened, the tips of his ears reddening. "I know you and Naruto were having sex," she continued, clinical and merciless. "He asked me for birth control." Itachi's gaze shifted to Sasuke, who suddenly found the corner of Tsunade's desk fascinating, his jaw clenched tight. "And I assume you knotted him." Sasuke's throat worked visibly as he swallowed, unable to meet either of their eyes, the private intimacy he'd shared with Naruto now dissected in the cold light of this office.
Tsunade leaned forward, her amber eyes locked on Sasuke's face. "I believe what you've formed with Naruto is a true bond." The words hit Sasuke like physical blows. His throat constricted as childhood bedtime stories—dismissed long ago as fantasy—suddenly crystallized into possibility. Tsunade's lips curved into a clinical smile as she nodded to her protégé. "Sakura, if you would. Let's test my theory with your pheromones."
Sakura nodded and closed her eyes. The air in the room seemed to thicken around Sasuke, becoming almost tangible. Though he noticed no scent, the pain in his chest intensified, sharp and insistent. Beside him, Itachi's knuckles whitened as he gripped the chair arms. After a long minute, the invisible pressure dissipated. Sakura opened her eyes, her forehead glistening with perspiration from the effort. "Thank you, Sakura," Tsunade said, satisfaction evident in her voice.
Itachi's voice came soft as a confession. "Sasuke." When Sasuke turned, his brother's face had transformed—eyebrows drawn together, lips pressed thin, eyes holding that particular shadow Sasuke had seen only twice before: once when he'd whispered his terrible secret about Orochimaru as a child, and again on that ash filled night when their home went up in flames.
Itachi's expression hardened as he turned to Tsunade. "What's the timeline?"
"Could be six months. Might stretch to a year." Tsunade's clinical tone couldn't mask the gravity of her words. "With bonds this rare, there's no reliable data."
The pain in Sasuke's chest flared. "Timeline for what?"
Itachi's eyes met his, rage barely contained beneath the surface. "For how long you'll survive without him."
Sasuke's gaze darted from Itachi to Tsunade as his fingers pressed against his sternum. Bonded. The word should have crashed through him like a death sentence, yet a strange lightness spread beneath his ribs instead. If Naruto's flame extinguished, his would follow—no choice to make, no life to endure alone. His lips parted slightly as understanding crystallized: they were tethered now, irrevocably. That night months ago when Naruto had packed his things—the possessive fury that had overtaken him wasn't just alpha instinct. It was the bond already forming, already fighting to preserve what his conscious mind hadn't yet recognized.
Tsunade's amber eyes flashed like lightning. "So do we have an understanding?" The question hung in the air like a blade.
"I will speak with our leader immediately upon return," Itachi replied, tension coiling in his voice. "All intelligence on Orochimaru's whereabouts—"
"You'll get everything," Tsunade cut him off. She jerked her chin toward Sakura, whose spine straightened instantly. "And she's coming with you. My eyes, my ears, my direct line. If Akatsuki so much as breathes wrong in this operation, I'll know before the exhale is complete."
Sasuke's gaze shifted to Sakura, his eyes narrowing. Something about her eager compliance with Tsunade's orders made his skin prickle. Was she truly there to help find Naruto, or to spy on them? To sabotage? His fingers twitched at his side.
Itachi cleared his throat. "A registered Omega in our headquarters..." He shook his head, doubt creasing his brow. "The risk of exposure is too great. How can we be certain she won't compromise everything we've built?" His voice carried the weight of years spent in shadows.
Sakura's lips curved in a faint smile as she held up her wrist, displaying a silver bracelet that Sasuke had seen her wear countless times at the university. With a practiced movement, she unclasped it and held it out for inspection.
"It's a sophisticated fake," she explained, turning it to reveal a tiny circuit board embedded in the metal. "Sometimes the best hiding place is in plain sight." She pressed a nearly invisible switch, and a small screen illuminated with coordinates. "The tracking signal can be manipulated to show whatever location we choose. Being registered eliminated any suspicion that I might be working against the system."
She reattached the bracelet with a soft click. "I've maintained my cover as a model registered Omega for three years. My file at the ORS shows perfect compliance, regular check-ins, and a thoroughly average medical history."
Sasuke's jaw tightened as he studied Sakura's face, searching for any flicker of deception. His instincts screamed caution even as Itachi nodded in approval beside him. "Welcome to the team," his brother said, but Sasuke remained silent, his fingers unconsciously moving to his sternum where the pain of separation from Naruto pulsed like a second heartbeat.
