The first thing was the smell.
Copper and rot and something else, something chemical, acrid, like ozone mixed with burned hair. It filled his sinuses and coated the back of his throat, and for a long moment that was all there was. Smell, and darkness, and a distant ringing that seemed to come from inside his skull.
Then the pain arrived.
It came in waves, each one cresting higher than the last. His ribs screamed when he tried to breathe. His left arm hung wrong, heavy and distant, nerve signals misfiring or blocked entirely. Something wet covered half his face, and when he tried to open his eyes, only one obeyed. his head was killing him.
Move, said a voice in his head that sounded like his own. You have to move.
He didn't move. He lay there in the dirt and the blood... his blood? someone's blood? and tried to remember how he'd gotten here.
There was nothing.
No, that wasn't quite right. There was something, but it was slipping away even as he grasped for it. Bright lights. The smell of antiseptic. A voice saying we're losing him or maybe we've lost him or maybe nothing at all, maybe that was just his dying brain inventing meaning where there was none.
His eyes—eye—focused.
Trees. Tall ones, the kind you didn't see outside of old-growth forests, their canopy filtering weak daylight into a grey-green murk. The ground beneath him was churned mud and dead leaves, and scattered among the leaves were—
Bodies.
His stomach lurched. He turned his head. Pain, sharp and white-hot through his neck, and saw them more clearly. Three, four, maybe more in the shadows. Some wore dark uniforms with armored plates. Others wore nothing recognizable at all, just torn cloth and exposed meat.
Get up, the voice said again. Get up now.
This time he listened.
Rising was an exercise in controlled agony. Every muscle protested. His ribs ground against each other in a way that suggested fractures, plural, and his left arm refused to bear weight. He got his right hand under him, pushed, made it to his knees.
The world tilted. He swallowed bile and breathed through his nose, shallow breaths, surgical breaths, the kind you learned to take when you needed steady hands and couldn't afford to let pain compromise your—
Surgical.
The word surfaced like a bubble from deep water. Surgical. He knew that word. He knew what it meant. He'd spent years perfecting those breaths, standing over open chest cavities and exposed viscera, his hands inside people who trusted him to put them back together.
He was a surgeon.
He was thirty-six years old.
He was... He looked down at his hands.
They were small. Too small. The fingers were slender and dirt-caked and young, the kind of hands that hadn't finished growing yet. The nails were torn and bloody. The knuckles were scraped raw.
These were not his hands.
Don't, the voice said. Don't think about it. Not now. Survive first. Think later.
Good advice. He took it.
He got to his feet. Swayed. Steadied himself against a tree trunk and looked around properly for the first time.
A battlefield. No, the aftermath of one. The fighting had moved on or ended, leaving behind the detritus of violence. Craters pocked the earth where something had exploded. Deep gouges in the tree bark suggested edged weapons or—or something else, something that didn't match any munition he could think of. And everywhere, everywhere, the bodies.
He counted twelve before he stopped counting.
Weapons, the surgeon's voice said... except it wasn't the surgeon, it was someone else, someone who thought in terms of threat assessment and tactical positioning. Equipment. Water. You need to scavenge before moving.
He looked down at himself. Dark clothing, torn in several places, soaked with blood that was tacky and drying. A belt with pouches attached. No obvious weapon aside from a—
A knife. Strapped to his thigh. Short blade, maybe six inches, with a ring pommel.
His hand moved before conscious thought caught up, drawing the weapon in a smooth motion that felt practiced. Muscle memory. The body knew this even if the mind didn't.
Okay. Okay, he could work with this.
The nearest body was maybe ten feet away, face-down in the mud. Male, from the build. He approached carefully, knife held in a grip that felt natural, and turned the corpse over with his foot.
What stared back at him was not human.
Or rather... it was human, technically, but wrong in ways that made his surgeon's brain rebel. The face was half-melted, skin sloughing off the skull in sheets, and the exposed flesh beneath had the consistency of candle wax left too long in the sun. One eye had boiled in its socket. The other was simply gone, the cavity filled with something black and viscous.
Chemical weapons. Had to be. Some kind of—
No. No, that wasn't right either. There were no chemical burns on the surrounding vegetation. No dispersal pattern consistent with gas or aerosol delivery. The damage was localized, precise, as if someone had simply pointed at this man and melted him.
Don't think about it.
He searched the body anyway. Found a pouch containing, metal stars? Throwing weapons of some kind, sharp-edged and weighted for flight. Another pouch held paper tags covered in symbols he couldn't read. A canteen, blessedly intact, sloshing when he shook it.
He drank. The water was stale and tasted of copper, but his body—this body—accepted it gratefully, and he felt some of the fog in his head begin to clear.
The other bodies yielded more. Another canteen. A field kit containing bandages, a needle and thread, and several small jars of what might have been medicine or poison. A longer blade, a short sword, almost, with a straight edge and a wrapped handle. The body carrying it had died cleanly, throat opened in a single slash, and for a moment he just stood there looking at the wound.
Perfect incision. Missed the carotid by millimeters... deliberate, probably, to ensure a slower bleed.
Whoever had done this knew anatomy. Knew how to make death hurt.
This was not his world.
The thought arrived with the force of revelation. The weapons, the wounds, the inexplicable damage patterns, none of it matched anything he knew. He'd worked trauma surgery in a major metropolitan hospital. He'd seen gunshot wounds and stab wounds and blunt force trauma from every conceivable angle. He'd never seen anything like this.
So. Either he'd lost his mind, or he'd lost his life and ended up somewhere else entirely.
Does it matter which?
No. No, it didn't. Either way, the immediate problem remained the same: survive.
He strapped the short sword across his back, the motion felt familiar, another gift from muscle memory, and transferred the useful supplies to his own pouches. The sun was descending toward the horizon, painting the canopy gold and amber. Maybe two hours of light left. He needed to find shelter, figure out where he was, determine if any of the survivors were—
Survivors.
He went still. Listened.
At first there was nothing but the settling silence of the forest: insects beginning their evening chorus, the distant call of birds, the creak of branches in a faint breeze. Then, so soft he almost missed it—breathing.
He turned slowly. The knife was in his hand again without his conscious decision, held low and angled. There. Behind a fallen log, maybe thirty feet away. A shape huddled in the shadows, trying very hard to be invisible.
He approached. The shape didn't move, but the breathing hitched... faster now, ragged with fear or pain or both. He circled the log, keeping low, and found—
A child.
No older than eight, curled into a ball with both arms wrapped around her knees. Female, from the face. Dark hair matted with blood. Wide eyes that tracked his movement with animal terror.
"Hey," he said, and his voice came out wrong, too high, too young, cracking on the single syllable.
"I'm not going to hurt you."
The child didn't respond. Just kept staring with those too-wide eyes.
He crouched down, making himself smaller. The motion sent fresh agony through his ribs, but he kept his face neutral. Calm. The way you learned to be calm when talking to patients' families, when the news was bad and you couldn't afford to let your expression make it worse.
"Are you injured?"
Still nothing. Then, slowly, a tiny shake of the head.
"Okay. Good. That's good." He didn't move closer. "Do you know where we are? What settlement is nearby?"
The girl's lips moved. No sound came out.
He waited. Patience was a surgeon's virtue. You couldn't rush a bleeder; you couldn't rush a scared child.
"K-Konoha," the girl finally whispered. "Konoha is... two days west."
Konoha.
The word meant nothing to him. He filed it away and moved on.
"Are there others? Other survivors?"
Another head shake. "Everyone... everyone's dead. The enemy ninja came and..." She trailed off, eyes going distant. Whatever she'd seen, it was too much to articulate.
Ninja.
The word landed like a physical blow. Ninja. Assassins. Shadow warriors. He'd thought those were legends, relics of feudal Japan, not... not this. Not modern-day soldiers fighting with throwing stars and melting faces and—
The Naruto manga.
It surfaced without warning, a memory from his old life, his real life. His nephew had been obsessed with it, had talked endlessly about chakra and jutsu and hidden villages. He'd never paid much attention... too busy, always too busy—but a lot of it had seeped through anyway. Ninja villages with absurd names. Elemental magic dressed up as martial arts. Child soldiers fighting wars that lasted generations.
Fiction. It had been fiction.
He looked at the dead bodies. At the melted face and the precision wound. At the scared girl who'd said enemy ninja like it was the most natural thing in the world.
Fiction.
Does it matter?
No. No, it fucking didn't.
"We need to move," he said. His voice was steadier now. The surgeon was taking over, the part of him that could compartmentalize shock and keep functioning through the chaos. "Before dark. Can you walk?"
The girl nodded uncertainly.
"Good. Stay close. Don't make noise."
He helped her up. She was shaking badly, but her legs held. He adjusted his grip on the knife—kunai, his nephew's voice supplied from a decade and a world away—and picked a direction.
