The security reader blinked red above the handle. Sasuke pressed his palm flat against his chest and felt the bond-separation ache come back into focus—Sakura's injection had blurred it to something manageable, but that was thinning now, the sedative dissolving out of his blood the way ice dissolves in a warm room, slow and then all at once.
He raised his hand and knocked. His knuckles stayed against the cold metal after the third rap, bone pressed to steel. He watched his own hand whiten where it rested against his thigh as the silence deepened. Five seconds. Ten. Overhead, the red light of the security reader blinked on, indifferent.
The lock clicked.
The door swung inward on pneumatic hinges that made no sound. The pheromones reached him before his eyes had finished their sweep—Naruto's scent, concentrated by months of confinement into something almost unbearable, hitting the back of his throat and spreading downward through his chest and into his hands before he had processed what he was smelling. His jaw tightened. The bond pulled at him with the particular violence of long denial, and for a moment the doorframe was the only thing keeping him upright, his free hand pressed flat against it while his other stayed on his weapon, finger outside the guard, because that much at least his body still knew how to do.
He forced his eyes to work the room in order. Left: Kabuto at the workstation, back to the door, fingers still on a control panel gone dark, the disorder of interrupted departure around him. Center: Orochimaru, arms loose, pale gold eyes meeting Sasuke's with the satisfaction of a man whose experiment had run exactly as predicted. Right: Kimimaro, unmoved beside the door, pale eyes already tracking Sasuke's hands.
Then Sasuke's eyes found Naruto.
He sat in a bolted chair under a single overhead light. The gown they had put him in was wrong—too large, too white, too institutional, nothing Naruto would have chosen, nothing that belonged on him—and it hung from his shoulders in a way that made visible what months of captivity had taken: the narrowed frame, the sharpened collarbones, the wrists that had lost the particular solidity Sasuke remembered from the first time he had held them still in their dorm room, trying to get a heat induced Naruto to take the suppressants.
But it was Naruto's eyes that stopped him. That blue—still that specific, impossible blue—Now it was in front of him and it was wrong. He had seen that blue go wide with shock in a hallway, go dark and stormy in a dorm room doorway, go soft and unfocused in heat, go bright and fierce when Naruto had looked at him and said the words Sasuke had not known he needed to hear. He had a favorite. He had catalogued them without meaning to, the way you catalogue something you are afraid of losing. This was none of those. This was the blue of someone who was afraid of being found. Afraid not for himself, but for Sasuke.
Naruto's jaw worked. The muscle in his cheek pulled tight, visible even in the harsh light, and he looked away first—deliberately, his eyes dropping to his cuffed hands, his shoulders hunching slightly as if to make himself smaller. Naruto was afraid that if he held the look, if he let their eyes stay locked for even a moment longer, he would break. Would scream, would fight against restraints he could not break.
"I've been waiting." Orochimaru's voice carried through the room, pulling Sasuke back from Naruto.
Sasuke kept one shoulder against the doorframe, the door open behind him. The sedative Sakura had administered was running out of time. He needed to draw them toward the hall, or leave enough clearance for Sakura to throw the canister from where she waited.
"I'm here now," he said, and his voice emerged flatter than he intended, stripped of the emotion that Naruto's pheromones were still sending through his system in waves. "Let him go."
The smile on Orochimaru's face widened, "You know I cannot do that," he said, and the mildness of his tone did nothing to soften the words.
Sasuke said nothing. Most of his attention remained on Kimimaro, whose hand had shifted fractionally at his weapon, whose eyes had not stopped tracking the minimal movements of Sasuke's free hand. The calculation was happening in real time now, the possibilities narrowing toward confrontation, and Sasuke made his decision fast—pulled his gun and leveled it not at Orochimaru or Kimimaro or Kabuto but at his own head, the barrel cold against his temple, his finger on the trigger outside the guard but ready, his eyes never leaving Orochimaru's face.
The room's atmosphere changed like a switch thrown.
Kabuto went down behind his workstation without a word, glasses catching the light as he dropped, both hands gripping the desk's edge. Kimimaro advanced one step—and stopped. The barrel hadn't moved. Sasuke's eyes hadn't moved. The pale guard stood there, reading the room, and what he found in it made his jaw tighten in a way it hadn't before. His hand found his weapon's grip. He did not draw.
The amusement left Orochimaru's face for the first time since the door had opened. His eyes narrowed, reassessing, and something colder moved behind them as he recognized what Sasuke was doing. Not surrender. Not negotiation. A different equation entirely, one that removed Naruto's value as leverage by making Sasuke's death the immediate consequence of any failure to release him.
"You're bluffing," Orochimaru said, but the certainty had gone from his voice.
"I'm not," Sasuke gritted out and gripped the gun harder as if in warning, "You need my pheromones. My genetics. You've needed them for years—since you first approached my family, since the experiments on me, since everything you built your research around. I'll go willingly. No resistance, no attempt at escape, full cooperation with whatever you want to extract or study or replicate." He paused, letting the weight of it settle. "If Naruto walks out now."
Naruto's voice came out desperate, "Don't. Sasuke, don't—run, just leave me. You know what he'll do, you know—"
Orochimaru's gaze cut to Naruto. Whatever he saw there was sufficient. Naruto's mouth closed. His eyes moved between the three of them in quick, involuntary arcs—Sasuke, Kimimaro, Orochimaru—the way eyes move when the body is calculating odds it already knows are bad. Behind the workstation, Kabuto's hands found the desk's edge again and he began, slowly, to rise.
"Bonded," Orochimaru said, and the word came out clipped, stripped of its usual silk. "Truly bonded. Which means you cannot be separated without destroying exactly what I need from you."
Sasuke's eyes cut to Kimimaro, who had closed the distance by another step. His hand moved to the trigger. Kimimaro went still. Sasuke turned back to Orochimaru and thumbed the hammer back. The click landed in the room's silence like a stone dropped into water, and Orochimaru's hands lifted slightly at his sides—not surrender, but acknowledgment.
"You've had months with him," Sasuke said. "You don't move this openly without a contingency for the bond—something to sever it, transfer it, contain the damage it does to both of us at this distance. You've prepared for this." He let the silence hold for a moment, watching the calculations move behind Orochimaru's eyes. "I'm not stupid, I've known you longer then I knew my own parents."
Orochimaru's hands settled back to his sides, but the smile that returned to his face was smaller now, more considered. "And if I call your bluff? If I say no, and wait for you to lower the gun?"
"Then I fire," Sasuke said, and made his voice carry the certainty of it. "And you get nothing. The bond collapses with my death—Naruto dies too, most likely, or is damaged beyond your ability to use. Your research loses its primary subject. All the years of observation, all the data you've gathered on Alpha-Omega bonding at this intensity, all the potential you've calculated for my genetics—it ends here, now, because you overplayed your hand."
He took a deliberate step backward toward the door, the gun still at his temple, maintaining the threat that kept Orochimaru's attention focused, that kept Kimimaro uncertain of whether intercepting him would trigger the final action, that kept all the variables in suspension while the seconds ticked toward deployment.
"Wait," Orochimaru said, and the word cost him something visible in the set of his jaw. He signaled Kimimaro with a small motion, two fingers extended, and the guard who had never been bested in combat released his weapon's grip and stepped toward Naruto's chair.
Sasuke kept the gun pressed to his temple, his focus split between Kimimaro's deliberate advance and Orochimaru's unnerving stillness. When the guard stopped at Naruto's chair and drew a key from his vest, Sasuke's pulse hitched—not in fear, but in the sharp, suspended moment before a trigger pull, when the world narrows to breath and intention.
Kimimaro's hand moved toward Naruto's cuffs. And Sasuke, without breaking his stance, his eyes, his absolute commitment to the performance of willing suicide, cut his gaze to the door across the hall and gave a single nod.
The door across the hall swung wide and Sakura came through it fast, Kurama right on her heel—both canisters already armed and extended, her thumb on the triggers before her foot cleared the threshold. The gas spread in a white-grey hiss that filled the space from floor level upward, faster than seemed possible, chemical density riding the air currents of the room's ventilation until visibility collapsed to arm's length in under three seconds. Sasuke saw Kimimaro's hand stop mid-motion at Naruto's cuffs, saw Orochimaru's head whip toward the intrusion with an expression that might have been admiration before it disappeared into the chemical haze, saw Kabuto's shoulders hunch lower.
Then the gas was between him and everything else, and he was moving.
He knew where Naruto was—had known since the moment the bond reasserted itself through the thinning sedative, could feel the precise vector of him like a line drawn through his chest—and he let that pull guide him through the obscured space. Three steps. Four. His hand found the back of the bolted chair, the metal cold under his palm, and he was reaching for Naruto's shoulder when Sakura's fingers closed around his arm with the force of someone who had expected exactly this.
"Don't." Her voice was hard, pitched to cut through the haze and his own biological urgency. "You can't touch him yet—not until we're clear and I can manage the pheromone response." She was close enough that he could see her face despite the gas, her mask sealed tight, her eyes visible through the clear visor and carrying something that was not quite fear and not quite anger but lived in the space between. "The bond's trying to reassert full contact. You touch him now, in this concentration, and you will both be subjected to the heat and rut."
Sasuke's jaw tightened. He stepped back—one step, then another, each one a separate decision made against the pull in his chest that had been building for months and was now almost gravitational. His hands found the wall behind him instead of Naruto's shoulders. He pressed his palms flat against the concrete and held them there.
"Clear first," Sasuke ground out, each word a rasp through the gas. "Then—"
A feral shout cut through the haze. "Watch out!" Kurama's warning came too late. A fist slammed into Sasuke's temple, cracking bone beneath the sedative's fog. His vision splintered into harsh flashes of white and black as he twisted, back colliding with concrete so hard it knocked the air from his lungs. His gun skittered away in the mist, swallowed instantly by the thick chemical curtain. Sasuke slammed off the wall and squared his stance—and saw Kimimaro stepping out of the gray, every movement precise, unhurried, eyes locked on him like a predator zeroing in.
Sasuke raised his arms, heart hammering as the counter-agent dwindled. The sedative's edge faded, Sakura's injection draining from his veins—time slowed at the periphery, his limbs lagging by agonizing fractions. Kimimaro feinted left, came roaring in from the right. Sasuke's block was a hair late; the guard's forearm caught his shoulder and spun him back into the wall. Pain exploded down his spine, vision going white for a moment, before his legs kicked him upright again.
"How is he still functioning?" Sakura's crisp voice sliced through the murk—equal parts medical frustration and disbelief.
Through bleary eyes, Sasuke tracked Kimimaro's even circling. No ragged breath, no hesitation—like a machine breathing clean air while they choked. He was holding a single lungful, thriving on its reserve. Forty seconds, maybe forty-five since the gas rolled in—Kimimaro was skating the edge of human limits, but he showed no sign of fatigue.
"He's holding his breath. One lungful," Sasuke rasped, voice rough like dried parchment. "Pacing himself."
"Then we move now," Sakura whispered, shifting to flank. Her medical bag glinted in the dim gaslight.
Kurama lunged through the mist, cloak of red hair trailing, and launched a kick into Kimimaro's thigh. The kick hit home with a thunk, and for a heartbeat the guard wavered—just enough for Sasuke to surge forward. Kurama rolled into him, bulldozing Kimimaro's balance. The guard snarled, recovered, and swung—a ripping blow to Kurama's ribs that cracked audibly against the gas's muffling effect.
Sasuke roared, the last of his counter-agent flaring. He leapt into the fray, underhooking Kimimaro's arm in a savage grip. With Kurama pressing the guard's opposite side, Sasuke twisted his hips, throwing the brute against the floor. The concrete met Kimimaro's back with a wet, bone-shuddering thud. He staggered, coughing in, and the gas flooded his lungs—eyes widening as the sedative spread through his bloodstream. His perfect control faltered; he took a stumbling stance, each breath labored.
Sasuke's side pressed to the wall, chest heaving. Kurama braced himself on the ground holding his rib in pain. The gas thinned now—Sakura's canisters spent, the room's ventilation limping back to life—but enough clung to the air to slow their senses. Kimimaro shook off the haze, pure lethal intent blazing as he launched a final assault.
He lunged. Sasuke twisted, but the world lagged. Kimimaro's fingers inches from his throat. In the same instant, Kurama slammed into Kimimaro's flank, hard enough to send the guard off-balance. Kimimaro's knees buckled. His hand clattered loosely as consciousness slipped away—no cry, just the hollow thud of a warrior finally broken.
Sasuke sagged. His legs surrendered him, and he slid down the wall until his back hit cold concrete. His pistol lay somewhere in the mist, useless now. Tunnel vision closed in, Naruto's face shining at the center. Across the room Naruto was slumped sideways—unconscious, cage of metal cuffs at his wrists now slack. His chest rose in shallow, even breaths, the gas-thinned light making him look nearly peaceful.
Sakura squared her feet beside Sasuke. "We did it," she rasped, voice hoarse but steady.
Sasuke managed a nod, the bond's pull on his chest aching with relief. Together they sat in the lingering mist, hearts still pounding, the room finally silent but for Naruto's soft breathing and the distant hum of returning air.
Sasuke looked at him—really looked, for the first time in months—and felt something settle in his chest that had been restless since the moment of separation. The bond's pull had not disappeared, would not disappear until they were in contact again and Sakura could manage whatever medical intervention was required, but it had changed quality. No longer directional urgency but simple presence. Here. In this room. Breathing the same thinning air.
The gun he had held to his own temple, lost somewhere in the gas and the fight, slipped from memory entirely. His hand had been reaching for it, or for Naruto, or for something he could not name, and now it dropped to the floor beside his hip with a sound he did not register. His head lolled back against the wall, and he felt consciousness receding, the last thing his body registering being the fading pull of the bond and the certainty, settling into him like something finally set down after months of being carried, that they were in the same room.
The gas had thinned to a haze, a faint chemical sting that lingered in the recycled air. Sakura stood alone in the center of Orochimaru's private office, the only upright figure in a room full of collapsed men, and let her eyes move through the space in a single rotation that took in everything her training demanded she catalogue: breathing, pulse, threat, escape.
Sasuke slumped against the far wall where he had fallen, chin dropped to his chest, the color drained from his face to something that matched the concrete behind him. His chest rose, though—shallow, even, the rhythm of someone whose body had finally surrendered to exhaustion rather than damage. She would check him properly in a moment. First, the room.
Kabuto lay folded sideways off his workstation chair, white coat pooled beneath him like a collapsed tent, his glasses cracked against the floor in a way that suggested he had tried to catch himself on the way down and failed. The frames were bent, one lens spiderwebbed, and his face where it pressed against the tile had gone slack with unconsciousness, mouth slightly open, breathing audible and unlabored.
Kimimaro had fallen face-down near the monitors, one arm bent wrong beneath his torso, the angle suggesting either a break or a dislocation she would need to assess before moving him. His pale hair spread across the floor in a fan that caught the overhead light, and his tactical gear had twisted with his body, straps and holsters and the empty sheath where his weapon had been.
Sakura completed her sweep and found what she had expected to find: Orochimaru was not among the fallen.
The desk drew her next—four steps across a floor still faintly slick with chemical residue. She pressed both palms flat against the surface, feeling for what her eyes had already found, the slight seam where the floor met the desk's base, the hairline crack that traced a rectangle in the tile.
The hatch. Already sealed from below.
She pressed against it with her weight, feeling for give, for any mechanism that might respond to pressure or rotation. Nothing. No handle visible from this side, no biometric reader, no release that would open the escape route Orochimaru had undoubtedly taken while they fought his guard. She straightened, wiped her palms on her tactical pants in a gesture that was part cleaning, part frustration, and did not let herself look at the sealed hatch again.
Everyone in this room was still breathing. That was the only calculation that mattered now.
When she turned back, Kurama was already on one knee beside Naruto's chair, a ring of keys stripped from Kimimaro's belt clutched in his fist. He worked the cuffs off Naruto's wrists with his right hand doing most of the labor—his left arm moved in short, compensated arcs, and every time he reached across his brother's body he pressed his elbow tight against his ribs, an unconscious bracing that spoke of injury he was refusing to acknowledge.
Fractured, or close enough. She had heard the crack when Kimimaro's fist had connected, had seen Kurama's face go white with it before he forced himself back into the fight.
Naruto's head lolled against Kurama's shoulder as the second cuff came free, his face slack with unconsciousness, the hospital gown they had forced on him gaping at the throat where the metal collar still hung. His wrists, now freed, showed the damage from the metal cuffs, and something else that had cut lines into his wrists-raw, abraded, skin broken in places where he had pulled against them.
Sakura went to Sasuke first—two fingers at his throat, pulse steady and slow, skin cold and clammy but not the blue of oxygen deprivation. His collar had pulled away with his collapse, and the bond mark at the base of his neck was raised and flushed, the skin around it showing the stress of prolonged separation and sudden proximity. Kabuto's pulse at the carotid was strong and regular, his airway clear; his Beta physiology had taken the full gas dose without resistance, and the unconsciousness would hold. Kimimaro she rolled carefully, supporting the damaged arm, and found what she had suspected at his wrist: a stuttering arrhythmia, every fourth beat dropping out, a body already running on fumes from the fight and from whatever Orochimaru had done to keep him functional.
She counted the irregular rhythm for thirty seconds, marking the timeline in her head. One hour, maybe less, before his systems would begin to fail without medical intervention. Tsunade's team, positioned outside the facility, could manage him. Could stabilize him, if they reached him in time.
By the time she reached Naruto, Kurama had freed both wrists and pulled his brother upright against his own chest, taking the full weight despite the rib that had to be screaming with every breath. Naruto's head rested against Kurama's shoulder, his hair—longer now than it had been in the photographs, matted and dull from facility conditions—brushing against his brother's jaw.
Sakura checked his pulse first, finding it faster than she would have liked, thready with the stress of unconsciousness and whatever Orochimaru had done to him in the hours before their arrival. She pulled one eyelid up with gentle pressure, checked the pupil's dilation—sluggish, but responsive—and moved to the other, finding the same. No sign of head trauma beyond what the gas would have caused, no fixed dilation that would suggest intracranial pressure.
Kurama watched her face the entire time, his jaw set and his hands locked around Naruto's arms in a grip that was part support, part refusal to let go. He had been waiting for this answer for months, she realized—waiting to know whether his brother was alive, whether he was whole, whether the experiments had taken something that could not be returned.
"Alive," she said, giving him the word first because it was the only one that mattered. "Stable enough to move, but he needs immediate care. A medical team is positioned outside the facility right now, and so do you, and we need to go."
Kurama's expression closed like a door—something she had seen before, in patients who had learned that medical authority was just another form of control, another system that would take what it wanted and leave them with less than they had started with.
"We're not going with your people," he said.
Sakura's breath caught—a single sharp inhale she did not let become more than that, a hitch in her professional composure that she forced back down before it could reach her face. "Naruto needs immediate care," she repeated, keeping her voice level, factual, stripping out the urgency that wanted to creep in. "I'm not equipped to manage everything he needs in a corridor. The bond—"
"Thank you," Kurama said, the words clipped and genuine at the same time, a strange combination that landed somewhere between acknowledgment and dismissal. "We'll find medical help on our own terms."
He did not look at the door, did not make any move toward it, but the intention was clear in every line of his body: the way he had positioned himself between Naruto and the rest of the room, the angle of his shoulders that suggested he had already mapped an exit route, the hand that had found Kimimaro's gun somewhere in the chaos and now rested with it against Naruto's back, hidden from direct view but present in the tension of his arm.
He did not trust the group that had just dismantled the facility around them, and he had no reason to start. Sakura understood this intellectually, even as she needed to find a way past it.
"There's one specific reason you cannot take Naruto out of this building without the medical team," she said, keeping her hands visible, her posture open, nothing that could be read as threatening. "The bond. The connection between Naruto and Sasuke—it's not metaphorical. It's biological. A true Alpha-Omega bond, rare and already formed, means their systems have been functioning as a single biological unit for months."
Kurama's eyes narrowed, suspicion sharpening into something more active, more dangerous.
"Separating them now," Sakura continued, "moving Naruto away from Sasuke before the bond response is medically managed—" She paused, letting the weight of the next words land. "It could send Naruto into hormonal shock. It could kill him. It could kill Sasuke. Both of them, from the same mistake."
Kurama's arms tightened around his brother, pulling him closer in a gesture that was purely protective, the gun pressing harder against Naruto's back. When he spoke, his voice was steady, but his hands were not—his knuckles had gone white where they gripped Naruto's hospital gown, the fabric bunching in his fist.
"You're lying," he said. "Buying time. Running the same manipulation Orochimaru ran on all of us for months."
Sakura felt the accusation land, felt the justice of it in a way that made her chest tight. He was not wrong to suspect. Everything about this situation—armed operatives, chemical weapons, the sudden appearance of rescue from an organization he had never heard of until today—screamed of hidden agendas and secondary purposes. She was asking him to trust her with his brother's life based on nothing but her word and a medical explanation that sounded, she knew, like exactly the kind of pseudoscientific justification Orochimaru would have used.
"I'm not lying," she said. "Please." She let him see that she meant it. The fear, real and controlled but present. The knowledge, specific and terrible. The absence of any angle she was working, any benefit she would gain from his compliance beyond the simple fact of two lives saved.
The corridor outside filled with sound—running boots, heavy and fast. Kurama's head turned toward the sound, the gun shifting in his grip, and Sakura felt her window closing. She had needed more time. Itachi and the rest of the team could not be far behind, but she had needed minutes, not seconds, to build the trust that might have convinced Kurama to stay.
The door came open hard and Itachi entered first—gun up, eyes moving through the room in a sweep that took in everything in under a second, the weapon tracking to Kurama against the wall with Naruto pulled to his chest and the gun now raised in his free hand, raised despite the fractured rib, despite the dead weight of his unconscious brother, despite everything that should have made him surrender.
Two Akatsuki operatives flanked Itachi in a tight stack, weapons finding their own angles, covering the room's corners.
Itachi did not lower his weapon. His eyes moved from Kurama's face to the gun in his hand to Naruto's unconscious form pressed against his chest, and Sakura could read the calculation happening behind the mask—hostile, armed, positioned between them and a high-value target, unknown variables that needed to be controlled.
The standoff held. Nobody moved. The only sounds were the faint hum of the facility's ventilation, struggling to clear the remaining gas from the air, and Naruto's shallow, even breathing against Kurama's shoulder.
Sakura stepped between them.
She pulled her mask off with one hand, letting it fall to hang against her chest, and raised both arms—turning first to Itachi's operatives, showing them her empty hands, her face, her status as non-threat, then back to Kurama with the same posture of surrender. She stood in the center of the room, the crossfire zone if anyone chose to fire, and said the only thing that might break the moment before it calcified into violence.
"Everyone stop."
She looked at Kurama directly, hands still up, palms open, and said only what was true: "We want everyone out safe. That's the whole objective. Nothing else."
Kurama's hold on Naruto did not loosen. The gun stayed raised, a line drawn between him and the rest of the room that he would not cross first but would not retreat from either.
Then Naruto shifted against him.
It was a small movement, barely conscious—his fingers curling weakly in the fabric of Kurama's hospital gown, a slight turn of his head that pressed his face more firmly against his brother's shoulder. His lips moved, shaping words without sound, and then with sound, barely above a whisper, rough with disuse and the gas's lingering effects:
"Sasuke."
Kurama went completely still.
He looked down at his brother's face—slack, unconscious, still not fully returned to himself—and then across the room at Sasuke, still slumped against the wall, chin on his chest, breathing the same shallow rhythm as the person who had just spoken his name without waking. The bond mark at Sasuke's throat was visible even from here, flushed and raised, responding to proximity even through unconsciousness.
He lowered the weapon.
The movement was slow, deliberate, the gun's barrel tracking down to point at the floor in a gesture that was not quite surrender but was as close as he could come to it. His other arm tightened around Naruto once more, a final protective reflex, and then he nodded—once, tight, the motion of someone who was stopping the fight not because he believed he was safe but because he could not find a way to keep fighting that would not cost him the thing he was fighting for.
Sakura let out a breath she had not known she was holding. She turned to Itachi, found his weapon still raised but his eyes on her now, asking a question without words, and she gave him the smallest nod she could manage—stand down, this is resolved, we have what we came for.
Itachi held for a moment longer. Then his weapon lowered, and he stepped aside to let his operatives begin the work of securing the room.
Sakura moved to Kurama's side, her hands finally free to do what they had been trained for, and found him looking at her with something that was not trust but was no longer active opposition either.
"The medical team," she said quietly. "They're waiting. We'll take you both out together, and we'll manage the bond properly. I promise."
Kurama said nothing. But when she reached for Naruto's wrist to check his pulse one more time, to begin the process of preparing him for movement, he did not stop her. His arm loosened enough to let her work, and that small allowance was the only answer he could give—the only one she needed.
