Consciousness returned the way it always did after a heat: in pieces, and none of them welcome.
First there was light—not the warm, gradual kind but the institutional kind, the kind that had no interest in whether you were ready for it. It burned through his closed eyelids and set off a dull throb behind his eyes that pulsed in slow, metronomic time with his heartbeat. His joints ached—wrists, hips, the knobs of his spine where they'd pressed into the thin mattress for what felt like decades. He swallowed and tasted something dry and faintly chemical, the ghost of whatever his saliva glands had been doing in his absence.
He lay still for a moment and let his body file its reports.
Every muscle carried the specific exhaustion of prolonged involuntary effort—the kind that left no injury, only depletion. His skin felt wrong against the fabric of the hospital gown, which had dried stiff in places and still clung damp in others. He didn't examine this too closely. There were stretches of the last however-many hours that existed in his memory only as sensation—heat, pressure, the phantom weight of someone who hadn't been there—and he already knew they were stretches he wasn't going to think about until he was somewhere else, some other version of himself who had the luxury of feeling embarrassed.
He turned his head toward the fluorescent source and squinted. White ceiling, white walls, the soft, relentless hum of the ventilation system—the Sound Facility presenting itself in its complete indifference. The collar had shifted during sleep, and its edge pressed now against the hinge of his jaw, a small persistent unkindness.
He made himself breathe. In through the nose. Out through the mouth.
His stomach made a sound like a ship in distress.
He ignored it and pushed himself upright, and the room listed sideways with a slow, nauseating tilt that made him grip the edge of the mattress and wait. The sheets felt damp under his palms. He didn't look at them. His hair hung in thick, matted hanks against his forehead, stiff with dried sweat, and the smell that came off his own skin when he moved was something he had no interest in cataloguing in detail. The heat had left him this way—hollowed out and encrusted, a husk of himself that remembered being a person and was working its way back toward it.
He breathed again. The room steadied.
He looked across the corridor.
Kurama's cell was empty.
The absence registered first in his body before it processed in his mind—a cold drop through his chest, quick and absolute, the same plummeting sensation as a missed stair in the dark. The cell was exactly as Kurama's had been: white walls, metal cot, institutional blankness. The cot across the hall was made. Not slept-in-and-tidied but made with the mechanical evenness of a surface that hadn't been disturbed.
Naruto's hands found the edge of the mattress and tightened.
He got his feet onto the floor. His legs didn't feel like his legs—they felt like suggestions of legs, collaborative fictions, and they shook as he put weight on them, the muscles registering their protest with the slow, measured language of something that had been used beyond its purpose. His vision greyed at the edges when he straightened too fast and he had to stop with one hand on the cell wall, head bowed, waiting for the grey to recede.
It receded.
He made it to the transparent door.
His reflection arrived before he was ready for it. The man looking back at him from the surface of the barrier had hollow cheeks and a damp, reddened quality to his skin that he didn't recognize as his own face at first. The circles under his eyes had deepened past purple into something closer to bruising. His hair was a wreck, the color dulled by oil and sweat, matted flat on one side and pushed up on the other in configurations that suggested his body had been doing things his mind hadn't monitored. The collar at his throat gleamed with its customary indifference, and something about seeing it in his reflection—worn on the outside of his body for anyone to read—made it feel heavier than it had a moment ago.
He leaned his forehead against the cold surface and looked across the corridor.
"Kurama," he said. His voice came out wrong—ground down to gravel, cracked at the high register, barely carrying across the eight feet of empty hallway. He cleared his throat, which accomplished nothing, and tried again, louder. "Kurama."
Nothing came back.
He pressed his palms flat against the barrier and turned his head down the corridor. "Hey," he said, toward the middle cells. "Is anyone awake? Can anyone hear me?"
A pause. Then, several cells to his right, Lee's voice—a little quieter than Naruto remembered, subdued in a way that wasn't natural to it. "Naruto. You are awake." Not a question. A statement with relief underneath it, careful and real. "How are you feeling?"
"Where's Kurama?" Naruto said.
A longer pause this time. He heard Lee exhale.
"They came for him," Lee said, and the subdued quality in his voice sharpened itself into something careful and deliberate, the tone of a person choosing how to deliver information they know will land badly. "The guards. Several hours ago—I think, it is difficult to say—while you were still—" He stopped. "They took him for testing."
The words arranged themselves in Naruto's ears and sat there.
Testing.
He stayed still with his hands flat on the transparent barrier and looked at the empty cell across from him and felt the word do its work. He had known what testing meant before he'd woken up in this place. He had known what it meant from the moment Orochimaru had catalogued the word in that conversational, clinical way—the way a butcher might say processing, comfortable with euphemism because the reality beneath it had long since stopped requiring explanation. He knew what it had meant for the hollow-shouldered man who'd been led out of the corridor in handcuffs, for Shukaku, for everyone in this wing whose name he was learning one cell at a time.
He knew what it meant for Kurama.
His stomach made its sound again—urgent and hollow, a physical need that didn't pause for dread. He hadn't eaten. He couldn't remember eating. The last thing his body had done that wasn't involuntary and biological felt like it had happened to someone else, in a different building, in a life where he'd had the luxury of turning down food because he wasn't hungry.
He pulled himself back from the door and turned to face the interior of his cell.
The camera in the corner observed him with its small, blinking red light—patient, unblinking, the way all the eyes in this building were patient and unblinking. The ventilation hummed its unvarying note. The fluorescent light said nothing and illuminated everything with equal, merciless flatness.
He sat back down on the edge of the mattress, put his elbows on his knees, and looked at the floor. The tiles were white. He had counted them before. He counted them again now, because it was something his mind could do that did not require him to think about what was happening to his brother in a room he couldn't reach.
As he sat there, mind empty of distractions, Naruto became aware of a dull ache beneath his sternum. It wasn't sharp enough to be alarming—just a persistent discomfort, as though he'd strained something during a workout. He wondered, with a clinical detachment that surprised him, if this was what happened when an Omega's heat went unsatisfied—another indignity his body had in store for him.
Naruto pushed that thought away and tried to focus on anything else. He'd been hoping, in some vague and superstitious way, that sitting still long enough would arrange the last few days into something legible. It didn't. His memory of the heat cycle was not like ordinary memory—it didn't come back in sequence but in isolated frames, each one arriving without context: Orochimaru crouching before him with gloved fingers and that particular quality of interest in his eyes that was somehow worse than hostility. The guard—Zaku, his mind supplied the name with a curl of revulsion—pressing himself against the glass. The camera's red light blinking in the dark. Kurama's back turned to give him privacy, the deliberate angle of those too-prominent shoulder blades.
Between the frames: nothing. A static haze where hours had been, biological noise so loud it had drowned out everything else. He didn't know how many times Orochimaru had come to the cell. He didn't know whether he'd slept or only lost consciousness. He didn't know if anything had been done to him while the haze was at its worst, and the not-knowing was a specific kind of fear that sat in his stomach separate from all the others, cold and unexamined.
He pressed his fingers against his forearm, checking. The skin was unmarked except for the old, faded remains of a blood draw from his arrival here. He checked the other arm. Nothing new. He exhaled through his nose.
That didn't mean nothing had happened. It only meant his arms were fine.
He pulled his knees up and rested his elbows on them and tried to hold himself still against the vertigo of not knowing. The heat had done what heats did—it had reduced him, temporarily, to something that ran on need instead of thought. He had been through it twice before in his life, and both times the aftermath had left him with this same raw, excavated quality, as if something essential had been burned off and hadn't finished growing back. The difference was that both times before there had been someone on the other side of it. Iruka pressing a cold cloth to his forehead. Sasuke—
The name caught in his throat like a fishbone, and he pressed a hand to the hollow ache beneath his sternum.
Sasuke was not a direction he could afford to go right now.
His stomach cramped violently—not hunger but starvation. His hands shook with the mechanical tremor of a body depleted beyond function. He hadn't eaten since before the fire alarm, before the needle, before everything changed.
He looked at the empty cell across the corridor. The cot. The blank walls. The particular absence of his brother.
Testing. The word sat like a stone in his gut. He saw Kurama again—rust-dull hair, jutting shoulder blades, knees pulled to chest. His brother, hollowed out by months of whatever happened behind those other doors. And now they'd taken him again.
He heard the footsteps before he saw anything.
They were distinct—not Zaku's aggressive stomp or Orochimaru's patient heel-clicks. These footsteps fell with mechanical precision, each identical to the last. Naruto recognized them from the morning of Orochimaru's pheromone experiment.
The white figure appeared at the end of the corridor and came toward him without hurry.
Kimimaro stopped at the cell. His face remained deliberately still, neither blank nor expressive. The black uniform fit perfectly. A jade pendant gleamed at his collar.
His eyes found Naruto on the edge of the mattress and stayed there for a moment, reading whatever they found.
"It's time," he said. His voice was low and unhurried. "You'll shower and eat."
Naruto stared at him. "No," he said.
Kimimaro's expression didn't shift.
"I want to see my brother first," Naruto said. "Tell me where he is. Tell me he's okay. Then I'll cooperate with whatever you need."
Kimimaro regarded him with the same even attention as before. Then—faintly, barely perceptible—he exhaled through his nose.
"Prisoner 205 is still in the testing phase," he said. "He will be returned to his cell when the session concludes." A pause. "He was ambulatory when I last observed him. The session is standard documentation, not a conversion procedure."
Naruto absorbed this.
He didn't know what a conversion procedure was, but the distinction mattered enough that Kimimaro had made it, which meant he'd known Naruto would need to hear it.
"Fine," he said. The word came out flat and grudging and cost him more than it should have, given how simple it was. "Fine. I'll go."
Kimimaro nodded once, "Approach the door."
Naruto did as he was told.
"The port," Kimimaro said from the other side of the glass.
The port was a slot in the lower section of the door, approximately the width of both hands placed side by side. Naruto had seen it used on Kurama, had watched his brother extend his wrists through that narrow opening. He crouched, a slow and careful motion—his knees were still unsteady, his legs operating at some fraction of their usual reliability—and fed his hands through the slot.
The cold hit his wrists first. Then the weight of the handcuffs, settling around each wrist in two crisp, successive clicks. Kimimaro worked without commentary, the process taking roughly four seconds from start to finish. The metal bit against his wrist bones when he reflexively pulled inward and he stopped himself from doing it again, forced his hands loose in the cuffs.
The door opened.
The corridor hit him with a chill his cell hadn't prepared him for. His skin prickled beneath the thin gown, goosebumps rising along his exposed limbs. He exhaled, watching for fog that barely formed before dissolving into the sterile air.
Standing in the corridor made Naruto feel exposed in a way that watching it from behind glass hadn't prepared him for. Cells stretched in both directions, each with its transparent front wall facing outward. The design was deliberate—guards could observe everything, while prisoners could only see what lay directly across from them. The rest remained hidden behind concrete and steel.
He looked instinctively toward Lee's cell.
Lee stood at his barrier, his full form visible now rather than just the pressed face Naruto had grown accustomed to seeing through the translucent wall. He was slightly taller than Naruto, with a build that suggested strength despite their circumstances. When Lee's face broke into a broad grin and he raised his hand in greeting—as if they were old friends crossing paths after months apart—Naruto found himself responding with an awkward lift of his cuffed hands.
Six cells lined the corridor—three on each side—from his own to the door. Beyond that, the hallway curved away from view. Lee occupied the second cell from Kurama's, with empty chambers flanking his brother's and his own. Across from Lee, a dark-haired man Naruto recognized from his first night stared blankly at the ceiling. Near the door, a petite woman with long black hair curled on her cot, seemingly asleep. But it was the occupant across from her that made Naruto's feet root to the floor. Shukaku sat hunched on his mattress, knees drawn to chest, wearing the same white hospital gown and metal collar as everyone else. He lifted his eyes to Naruto's, resignation washing across his features before he turned away. Kimimaro's hand pressed between Naruto's shoulder blades, urging him forward.
Kimimaro guided him to the door at the end of the corridor, pressing his palm against a small scanner mounted on the wall. The device blinked—red, then green—and Naruto heard the subtle click of the lock releasing. Beyond lay another sterile hallway, longer and wider than the cell block, with unmarked doors punctuating the blank walls at irregular intervals. The passage terminated in a T-intersection some distance ahead. Naruto felt Kimimaro's hand between his shoulder blades again, propelling him forward before he could glance back toward the cells. Staff in various uniforms passed them without a second look, their eyes sliding over him as if prisoners in restraints were simply part of the landscape.
After what seemed an endless march through identical corridors, Kimimaro halted before a door labeled "Sanitation Station." Unlike the security doors they'd passed, this one required no palm scan—he simply turned the handle and motioned Naruto through with a slight incline of his head.
The sanitation room was all hard surfaces and echoes. White tile lined the walls and floor, interrupted only by stainless steel fixtures and floor drains positioned at precise intervals. Three showerheads protruded from one wall, unadorned by curtains or dividers—just exposed pipes and utilitarian sprays designed for function rather than comfort. The lights overhead were the same merciless fluorescents that illuminated every corner of the facility, leaving no shadows, no place for privacy. The room held the lingering humidity of recent use and smelled faintly of industrial disinfectant.
Kimimaro positioned himself by the only door, his back to the wall, eyes forward. "Hands," he instructed, producing a small electronic key from his pocket.
Naruto extended his wrists, feeling a small measure of relief as the cuffs released. He rubbed at the red marks they left behind, skin tender where the metal had pressed against bone.
"You can go now," Naruto said, attempting a casual tone. "I'm pretty sure I can handle a shower without supervision."
Kimimaro's expression didn't change. "Remove your gown and shower. You have five minutes."
Naruto's face drained of color as Kimimaro planted himself against the wall, arms crossed, eyes fixed forward. The collar around Naruto's neck suddenly felt heavier, the metal biting into his skin as he swallowed. His fingers clutched the thin fabric of his gown, knuckles white, knowing there was no choice, no privacy, no dignity they would allow him to keep.
