The tower always sat where the water got thickest.
Ren felt it before he saw it—the air turning heavy, wet enough to sit on his tongue. Rot layered over salt, over old oil. Sound didn't carry right out here. Every step he took through the flooded belt died early, swallowed by the brown water and the sagging shells of warehouses.
Then the tower rose out of it, narrow and wrong for the space it occupied. Too tall for anything around it. Too clean in its lines compared to the collapsed roofs and algae-slick walls sinking into the flood.
He knew the place.
Didn't need the broken strip of letters to tell him.
RESEARC – K
PRIVATE CONT RA T R
CLEARANCE: IRRELEVANT
The words scraped across his eyes anyway.
Antennas bristled from the top, bent and tangled. Cables sagged between them. Some still hummed—he could hear it even from here, a thin electrical whine threading through the damp air. It set something off behind his eyes, a pressure that didn't belong to him.
The water shifted at his ankles.
Not wind.
Something in it moved away from him—not fast, not panicked. Just… refusing contact. The surface dimpled in shallow rings that didn't match his steps.
The sea-kami didn't like this place.
Neither did the smaller things tangled in the wires above. He couldn't see them clean, but when the floodlights flickered, something in the gaps flickered wrong with them. Not shadow. Not light. Interference.
His skin tightened.
The tower did that. Always had.
He stepped up onto the cracked concrete lip at the base. The air changed immediately. Drier. Thinner. The hum from above sharpened, cutting instead of pressing.
For a second, the pressure in his chest misfired—breath catching halfway in, like his body had forgotten the rhythm.
Then the door hissed open.
Bleach hit him first. Sharp enough to burn the back of his throat. It overrode the rot, but didn't erase it. Just layered on top.
Inside, the sound came back wrong.
Footsteps carried too far. Echoed off surfaces that should have dampened them. The floor under him shifted from grit to smooth tile to rubber in uneven patches, each one pulling at his stride differently. His bare feet stuck, slid, adjusted without asking him.
Air moved through the corridors in thin, directional currents—one cold stream cutting across his chest, another warmer one pushing at his back. The vents clicked overhead, out of sync.
He didn't slow down.
Didn't need to be told where to go.
The room waited where it always did.
Glass wall. Cheap monitors. Treadmill already running.
The belt spun too fast.
They always set it that way.
Two guards stepped in behind him. Hands on his shoulders—firm, practiced. Not rough. They didn't need to be.
He stepped up onto the platform before they pushed.
The rubber met his feet mid-motion. Too fast. His first step hit wrong—ball of the foot catching late. His ankle dipped, corrected. Second step overcompensated. His rhythm stuttered, then snapped into place by the third.
Slap—slap—slap—
Too fast for the old belt.
It wheezed under him, motor catching every third rotation.
Hands moved in close. Tape pressed against his skin—wrists, chest, neck. Too tight in places, too loose in others. Cables threaded in, pulled, adjusted. One tugged across his collarbone and bit.
"Hold him steady," one of them said.
"I am."
"I said steady—"
"I got it."
They finished anyway. They always did.
The guards stepped back.
The belt didn't slow.
Ren's breath hitched once, twice—then found a shallow rhythm it could hold.
Foxfire pressed behind his ribs. Not rising yet. Just there. Waiting.
On the rack beside the glass, the monitors flickered alive. Analog lines jittered into place. Heart rate—too fast already. Thermal—hot joints, hotter chest. A third readout in green numbers:
SOUL DENSITY
The digits jumped before settling, like they couldn't decide where to land.
Behind the glass, two technicians shifted in their biosuits.
"Baseline's off," the shorter one said.
"It's always off," the taller replied, not looking up from his tablet. "Mark relative. Spike at two-point-three when his heart crosses baseline plus thirty."
"That assumes his baseline holds."
"It won't. Log it anyway."
Ren heard them through the ceiling speaker. Their voices flattened, metallic, like they were being pushed through something too small.
He glanced at the glass.
Not a mirror.
Never had been.
His reflection lagged a fraction of a beat behind him. Enough to notice if he didn't blink.
Stringy arms. Narrow shoulders. Scar on his left side—crooked, pale, pulling slightly when he breathed too deep.
And over that—
Something else.
A fox shape leaned across his shoulders. Not separate. Not attached clean. Its edges jittered, resolving and unresolving in thin lines of static. Ears forward. Tails—one, then not one, then back again.
When he blinked, it didn't.
"Again," the speaker said. "Shift."
Ren exhaled through his teeth.
His next step hit slightly off-center. The belt dragged him half an inch sideways before he corrected. His hip followed late. Spine twisted, then realigned.
There.
Misalignment.
He held it for a step too long.
The room slid a fraction out of place. Not visibly—just enough that his foot landed where the ground had been, not where it was.
He stumbled.
Caught it.
Didn't let it collapse.
Foxfire surged in response—not up, not out. Sideways. Pressure spreading unevenly along his ribs, one side tightening before the other.
His breath broke.
In—too shallow.
Out—too fast.
The monitors spiked.
"See that?" the shorter tech said.
"Lagged compensation," the taller replied. "He's not aligning clean."
"Or he's learning not to."
"Run him."
Ren forced the rhythm back.
Slap—slap—slap—
The whir of the treadmill separated. Motor grind. Belt flutter. Roller squeak. Each sound sat in its own place, no longer blending.
Air dried in his mouth. Antiseptic stung the back of his throat. Sweat tracked down his spine, cooling unevenly where the vents cut across him.
The fox in the glass thickened.
Not closer.
Clearer.
Its outline held for a full step. Then wavered. Then held again.
His left shoulder tightened first. Muscles pulling too hard, too early. His right lagged behind, soft for half a beat before catching up.
Asymmetry.
His stride shortened without permission.
The green numbers jumped.
"Subject 3-B remains stable under induced manifestation," the taller one said.
"Stable?" the other snapped. "Look at that spread."
"Stable enough for the buyer. They're not paying for clean."
Ren's teeth ground together.
Subject.
3-B.
His next inhale caught halfway in. His ribs resisted expansion, pressure building under them instead of moving through.
The fox's head tilted in the glass.
Not matching him.
He pushed harder.
The edges of the room snapped sharp.
Every light click counted itself out. Every cable hum threaded into the next. He could feel the electrical noise from the monitors skimming along his skin—fine, constant, like static before a storm.
The fox didn't move when he did.
It stayed.
Watching.
The numbers spiked again.
"Two-point-three," the shorter tech said.
"Mark it."
"That's higher than—"
"Mark it."
Ren's vision pricked red at the edges.
Not from the run.
Too fast.
He knew this pattern.
Too clean a rise. No bleed-off. No stabilization phase.
"Loop's broken," he said under his breath.
He took one more step.
The belt dragged.
His foot landed late.
The fox's outline snapped too sharp.
Feedback.
He hit the emergency stop.
The belt screamed and lurched under him. His knees buckled as the motion cut. His weight pitched forward, then back. He caught himself on the rail—hand slipping on sweat, skin sticking for a fraction before sliding.
The monitors went jagged.
"Hey!" the speaker crackled. "We didn't—"
"Your feedback loop's drifting," Ren said, breathing uneven, words breaking between inhales. "You're stacking signal on signal. No dampening. It spikes—then it spikes the spike."
Silence.
Then—
"That's not your concern," the taller tech said, tighter now.
Red flashed across Ren's vision again. His head throbbed, pressure building behind his eyes. The foxfire didn't surge—it hammered, pulse after pulse, out of sync with his heartbeat.
He ripped the tape from his chest.
Skin pulled with it. Heat followed. One cable snapped loose with a spark. The monitor shrieked.
He tore the rest free. Wrists. Neck. Each pull sharper than the last, nerves firing late and wrong.
His hands shook when they came away.
Not large movements. Fine tremors along the fingers. He flexed them once. They didn't settle.
"Come in here and tape them back yourself," he said, voice rougher than he meant it to be. "I'll help."
The speaker didn't answer.
His balance dipped.
The floor felt slightly tilted—no visible angle, just enough that his weight didn't settle where it should. He shifted. Overcorrected. Stilled.
His breath came in short pulls. Each inhale caught at the top before dropping through.
Not done yet.
The comedown lagged.
He stepped off the treadmill.
The change in surface hit him wrong. Rubber to smooth tile. His foot stuck, then slid. His ankle rolled a fraction before he caught it. His hip followed late again.
Still misaligned.
He walked it out anyway.
Each step a correction.
By the time he reached the glass, the tremor had moved up into his forearms. Subtle. Persistent.
The fox-shadow paced with him.
One step out of sync.
He lifted his hand.
Paused.
His palm hovered a hair's breadth from the surface. The glass radiated cold. His skin prickled before contact, nerves firing ahead of touch.
He pressed his hand flat.
For a second, his fingers didn't feel like his. Position lagging behind sensation. The outline in the glass didn't quite match the pressure.
He swallowed.
"…You're enjoying this?" he said, quieter now. Not aimed outward. Not fully.
The fox didn't answer.
It never did.
Behind the glass, movement blurred.
"Get him back in the cell," the shorter tech said. "We got what we need."
"What about the anomalous trace at—"
"We'll scrub it."
"That spike wasn't clean."
"It doesn't have to be."
A pause.
Then, lower—
"You keep pushing like that, you're going to break him."
"We're not here to fix him."
Ren's mouth tightened.
His hand slipped off the glass. Sweat cooled fast now, air from the vents cutting across his skin. Where it dried, his skin pulled tight, prickling.
His fingers still trembled.
He wiped them on the treadmill rail. The metal felt colder than it should have.
Footsteps approached behind him.
He didn't turn.
They took him anyway.
Back through the corridors.
The air shifted again—cold stream across his chest, warm at his back. The floor changed under his feet. Rubber. Tile. Grit.
Bleach layered over something older.
His steps echoed too far ahead of him.
And under it—
faint, thin—
the same electrical hum from the tower's crown, threading through the walls, touching the back of his skull like a thought that wasn't his.
