Chapter 2

The detention room smelled like dry-erase marker and old rain. Five chairs scraped into a crooked circle; the clock above the door read 4:17 p.m. same as yesterday and the day before that.

Kota leaned back until his chair balanced on two legs, one sneaker tapping the radiator. “So we’re calling this the After-School Apocalypse Club now? Cute. Who’s taking minutes?”

Rin slid a battered composition notebook across the desk. “I am. Don’t make it weird.” Her pen hovered, then scratched the date—yesterday’s date—into the margin.

Yuna sat by the window, knees drawn up, staring at the empty baseball field below. “The rewind happened at midnight again. I counted the bells. Same number, same silence after. We’re the only ones who noticed.”

Haru drummed his fingers on the desk, the rhythm quick and nervous. “My little sister still thinks it’s Thursday the first time. Mom packed the same bento twice. I ate it twice. I’m starting to hate egg rolls.”

Mio, half-hidden behind an open math textbook, didn’t look up. “If we’re the only ones retaining memory, then either we triggered the loop or we’re the only ones the loop can’t overwrite.” Her voice was soft, almost apologetic for existing.

Kota let the chair drop forward with a bang. “Great. We’re bugs in the code. Question is, who wrote the code and why do they keep letting detention kids find it?”

Rin flipped to a clean page. “We need rules. First: no telling anyone outside this room. Second: we each bring one new observation every reset. Third—” she glanced at Mio—“we don’t experiment on ourselves until we understand the rules.”

Haru snorted. “Too late. I already tried dying in the loop.”

Four heads snapped toward him.

Yuna’s voice cracked. “You what?”

“Bike into traffic, yesterday morning. Felt the truck, then woke up in my bed at 12:01 a.m. Same alarm, same socks on the floor. Zero pain, zero scars. So either we’re immortal or the universe just reloads us like a bad save file.”

Silence pooled. Rin’s pen hovered, then wrote “Haru—test subject #1” and immediately crossed it out.

Kota’s usual smirk had slipped. “Next time you feel like science, warn the group chat first.”

“I didn’t think it would stick,” Haru muttered.

Mio closed her textbook. “We should map the radius. If the effect is localized, maybe we can leave it.”

“Already tried,” Yuna said. “Train to the next station. Got three stops before the conductor announced we were returning to the terminal for ‘technical difficulties.’ Back at the gate at 11:59 p.m. Same loop, tighter net.”

Rin added the note. Her handwriting was getting smaller, like she was trying to fit an entire future into the margins.

The door handle rattled. Everyone froze.

It was only the janitor’s cart squeaking past, but the moment broke something loose. Kota stood, pacing the narrow strip of linoleum between desks. “Okay, new theory. We’re not bugs. We’re witnesses. Someone wants a record of the end of the world, and we’re the only ones sober enough to keep it.”

“Cheerful,” Rin said.

“Realistic,” he shot back. “Yuna, you said the sky glitches at 11:58, right? Describe it again.”

Yuna’s fingers tightened around her knees. “Colors invert for three seconds. Then the moon jerks like a skipped frame. Then nothing until the bells.”

Mio spoke without lifting her eyes from the desk. “I saw a bird fly backward yesterday. Only for a second. I thought I imagined it.”

Haru laughed once, short and sharp. “Birds are unionizing. Great.”

Rin closed the notebook. “We need to decide what we’re actually doing here. Documenting is fine, but if we can’t break the loop, we’re just very thorough ghosts.”

Kota stopped pacing. “Then we break it. Tonight. All five of us, roof access, watch the glitch together. If something rewinds us, we hold on to each other—physical anchor. If the loop is information-based, maybe contact keeps the data from resetting.”

Haru raised an eyebrow. “You volunteering to hold my hand, pretty boy?”

“Only if you promise not to die again.”

Yuna’s voice cut through the banter, small but steady. “I’ll go. But if it fails, we stop testing on Haru. Or anyone.”

Mio finally looked up. Her eyes were darker than usual, like the loop had already started pulling color out of them. “One more rule. If any of us starts forgetting the previous days, we tell the group immediately. No lone heroes.”

Rin wrote it down. The pen scratched louder than it should have in the quiet room.

Outside, the sky was the same bruised purple it had been at 4:22 p.m. for three resets. A crow landed on the baseball backstop, cawed once, then flew the exact same arc it had yesterday.

Kota watched it. “Even the birds are on schedule.”

The final bell of after-school activities rang somewhere down the hall—single tone, same as always. Five pairs of eyes flicked to the clock: 4:29 p.m. Thirty-one minutes until the building locked.

Rin stood, tucking the notebook under her arm. “Roof at 11:40. Bring whatever you think might survive a reset. I’m bringing the minutes.”

Haru saluted with two fingers. “See you all in the past.”

They filed out one by one. Yuna lingered by the door, glancing back at the empty chairs.

“Rin,” she said quietly. “If this is the last reset we remember, I’m glad it was with you guys.”

Rin’s reply was almost too soft to catch. “Same.”

The door clicked shut behind them.

Eleven hours later the roof access door opened with a reluctant squeal. Five shadows climbed the last flight, shoes scraping concrete. The city below looked frozen mid-breath—streetlights stuttering, traffic signals locked on yellow.

Kota checked his watch. 11:39 p.m.

“Everyone linked?”

They formed a loose circle, hands gripping wrists, shoulders touching. The air tasted metallic, like a storm that had forgotten how to rain.

Mio whispered, “If we wake up tomorrow still holding on, we’ll know something changed.”

The minute hand crawled.

At 11:58 the sky inverted—stars bleeding into negative space for three long seconds. A low chime vibrated through the concrete under their feet.

Then the loop tried to take them.

The world didn’t snap back cleanly this time. It stuttered. Kota felt his fingers slip through Rin’s wrist like static. Yuna’s voice fractured into overlapping echoes—“hold on—hold—hold—”

Haru’s grip tightened, almost painful. “Don’t let go—”

For one impossible second they existed in two places: on the roof and already back in their beds, alarms about to ring.

Something tore.

Midnight hit like feedback.
