Two days later, the city changed again.

They had kept the same pattern—move at night, hide by day, keep west. They slept in a stairwell the first day, in the back of a shuttered ramen shop the second. They ate tight: rice stretched thin, two candy bars cut into four pieces, a little water each. No one complained. Complaining burned energy.

By the second night, the streets opened into longer boulevards. The buildings here were lower, wider, set back from the road. Weeds choked the medians. Billboards leaned at bad angles. A burned-out bus lay on its side, half melted into the asphalt like a fossil. The air smelled dry, dusty, with a hint of sea carried far on the wind.

"Feels… empty," Miko whispered.

"It's not," Riku said.

He was right.

They reached an intersection where five roads met like a star. Riku slowed, eyes scanning every angle. At first he saw nothing, only the usual—dead cars, trash, a light pole bent at the base. Then he heard it. Not one moan. Many. A low, rolling sound like wind through a pipe.

He killed the engine and lifted a hand. "Quiet."

The girls froze, listening. The sound grew—layered groans, foot drags, the slap of soft things against pavement. It came from the west and south both. Riku took the thermals from the dash and peered down the longest boulevard.

He didn't need the thermals. He could see it with naked eyes now. Shadows moved in a sheet across the far end of the street. Not a cluster. A flow. Zombies. Hundreds. Maybe more. They filled the road from curb to curb, spilling into the sidewalks, bumping into cars, climbing, falling, rising again. They moved like a slow river, thick and ugly.

Hana made a tiny sound and covered her mouth. Miko pulled her close.

Ichika swallowed. "We're not getting through that."

"Not there," Riku said. He checked the side streets. East was back toward places he didn't want to go. North was a row of tight lanes between low warehouses. South carried its own thin line of movement, a smaller flow that bled into the big one.

He put the Rezvani in neutral and let it roll backward into shadow behind a delivery truck. "They're migrating. Something pulled them—sound, fire, who knows. We wait."

"How long?" Suzune asked.

Riku listened. He watched the pace. The big river moved steady. The smaller flows joined and thickened. If they waited, it might thin here in an hour. Or it might get worse.

"Scout," he said. "I go on foot. You stay. If I'm not back in ten, you lock the doors and don't move. No horn unless I say."

Suzune's mouth tightened, but she nodded. "Go."

He slipped out into the alley air. The night was clear and cold. He moved low along the wall, past a noodle stand gone to mildew, past a stack of plastic crates turned brittle by sun. He reached the corner and studied the swarm again. The mass was center-left on the boulevard, flowing west to east. The rightmost lane brushed against a row of parked compacts. A narrow space opened there, thinner than a lane, more like a broken gutter.

He traced side streets with his eyes. Three blocks north, a parallel road ran clean, then curved around to meet the west road past the worst of the swarm. The problem was the first block north: a chokepoint where two cars had crashed nose to nose. A van lay sideways behind them. A Rezvani could push one, maybe two. Three would eat time they didn't have.

He looked across the intersection and saw a solution. A small grocery on the corner had an old alarm bell unit still bolted above the door and a beat-up compact car parked tight to the curb. Its windows were intact. Battery might still hold a charge. Car alarms in this city liked to die slow.

Noise pulls. Zombies follow.

Riku doubled back. Inside the Rezvani, he spoke fast and simple. "Plan. I throw rock, hit car, alarm screams. Swarm drifts to sound. When the right edge thins, we punch north. I'll clear the chokepoint. Everyone belts tight. No panic."

Ichika stared. "You sure that thing still works?"

"No," he said. "But it's better than hoping."

He took a fist-sized chunk of broken concrete from the gutter and moved to the grocery's shadow. The car sat three meters away, driver's window catching a sliver of sick moon. He breathed out, felt the weight, and snapped the throw.

The concrete hit the glass with a hard thud and a sharp spider-crack. For a breath, nothing. Then the car blinked its hazards and the alarm coughed to life like an old smoker—warbling, ugly, loud.

The effect was instant. Heads in the front rank of the swarm turned like sunflowers. The flow tilted. Bodies leaned. The whole mass oozed sideways toward the noise. The river didn't stop, but the right edge tore away, drawn across the street like silk pulled by a hand.

Riku ran back and slid into the driver's seat. "Now."

He started the engine. The Rezvani rolled out with its nose low, headlights still dead. He aimed for the bread-thin gap by the compacts, letting the tires ride the curb. Zombies nearest the right lane had their backs to them, drawn to the screaming car. A few turned at the edge of sense, but too late. Riku threaded the big bumper between a mirror and a door handle and kept going, forty meters, sixty—metal scraped, glass popped, but the truck held the line.

"Left—now," Suzune said, pointing. The gap opened toward the side street, and Riku took it. He turned hard, the Rezvani's weight biting asphalt, and slid into the narrow lane north.

The car alarm cut off. Silence crashed back—and with it, the second wave of attention. The rear edge of the river turned, scent or sound catching them. They didn't scream. They began to follow.

"Hold on," Riku said.

The chokepoint appeared ahead exactly where he'd mapped it: sedan nose to nose with a delivery car, a van sideways behind them, front wheels in a pothole. No clear way around. No time to reverse.

Riku didn't brake. He aimed the bumper at the seam between the sedan and the delivery car, caught the metal where it was already wrinkled, and drove. The armored front hit with a deep, stomach-punch clang. The sedan's axle popped. The car shifted half a meter, then a full one, scraping a path just wide enough for tires.

Zombies poured into the far end of the lane now, pulled by engine and movement. The first sprinter hit the rear quarter and bounced; another got its arm caught on the roof rail and scraped away, howling in a wet, animal way.

"Go!" Ichika shouted, useless but honest.

"I'm going," Riku said, teeth tight.

He feathered the throttle, kept traction, and shoved the sedan that last inch. The Rezvani squeezed through, metal screaming on metal. The van behind the sedan tilted in its pothole, threatening to roll. It didn't.

They burst out into the parallel road, cleaner than the boulevard by a miracle of chance. Riku turned west again, putting buildings between them and the river. He kept speed low to hold control but hard enough to widen the gap.

"Are they still coming?" Hana's voice shook.

Miko looked back. "Some are. Not all."

"Forward," Riku said. He took three more turns in a box, then cut across a small park, dodging benches and a slide tipped on its side. The park's chain-link fence lay bent; he drove over it and felt the truck shrug off the resistance.

Three blocks later, he killed the lights, let them drift into a service alley, and cut the engine. The night fell heavy again. The sound of the swarm faded to a blanket murmur instead of a hunt.

They listened. No fast steps. No claws. Riku let his grip loosen on the wheel by a fraction.

"We're clear," he said.

Suzune exhaled hard. Ichika swore under her breath, not at him this time. Miko hugged Hana, who shook all over, then hiccuped and laughed once in a broken way.

"That was… loud," Hana whispered.

"It worked," Riku said.

They stayed in the alley until the sky went gray. No one really slept. When light came, they moved the Rezvani deeper into a garage with a half-broken door and took turns resting. Riku ate half a candy square and forced himself to drink three mouthfuls of water. He hated the taste of thin plastic now. He would drink it forever if it kept them alive.

The second day after the swarm, they tried to put more distance behind them. They took a ring road that wrapped around a stadium, then cut through a cluster of schools that had turned into small fortresses and then into graves. Chalk still clung to one board visible through a broken window. A child's handwriting. Hana looked away quickly.

By dusk, they reached a wide arterial road that swung under a rail line. Riku scouted ahead on foot and came back with a look they understood now—tight mouth, eyes measuring.

"What is it?" Suzune asked.

"Another flow," he said. "Bigger." He pointed west with his chin. "They're cutting across the underpass like a packed train. Both sides are pinned—cars and rubble. The only clean lane is where they are."

"Can we wait it out?" Miko asked.

He shook his head. "They're not crossing in one direction. They're circling the pillars. Something's holding them there." He didn't say what. It might be a sound under the bridge, a trapped animal, a broken speaker, a generator. Or nothing at all. Sometimes they just gathered and never left.

Ichika rubbed her forehead. "So we go back."

"Back is thinner streets. We'll crawl all night and end up closer to raider routes," Riku said. He looked at the map, then at the rail line overhead. Concrete pillars every ten meters. The embankment to the right was a steep incline of loose rock and dirt. The left side was a tangle of rebar and concrete chunks from a collapsed sound barrier.

He made the choice he always made. Not the safe choice. The least bad one.

"We split," he said. "Two steps. First, we pull the horde to the east mouth of the underpass. I can do that with noise. Second, when the west mouth thins, we punch through the clear path under the rail. We hug the pillar line and keep the speed steady. No stopping. If anything gets in front of us, I move it with the bumper. Everyone belts tight."

Suzune didn't like it. She didn't argue. "What noise?"

Riku glanced at the line of cars abandoned along the curb. One, a small sedan, still had all its windows. Another, a little truck, sat with its hood up and a clean battery someone had forgotten to steal. He checked it. The leads were still snug.

He pulled duct tape from his pocket and a length of wire from the Rezvani's kit. In three minutes, he had the little truck's horn wired to honk when the hood shut. He propped the hood with a piece of pipe, taped the pipe so the wind wouldn't knock it, then climbed inside the cab and kicked the foot brake loose. The tiny truck rolled.

He guided it by pushing at the door frame, letting it drift toward the east mouth of the underpass. When it reached the slope, he gave it one last shove. It rolled faster, wobbled, then hit a broken curb and the hood slammed shut.

The horn screamed.

The underpass moved like a living thing. Heads snapped. Bodies surged. The mass on the west mouth leaned east as if the whole pile had been tipped. The lane behind the rightmost pillars opened, not wide, but open.

"Now!" Riku shouted, already running.
