Monday, 23 June 2025, 12:01 PM | Gym Room—School, Tokyo, Japan | Weather: Cloudy, 26°C.

The gymnasium felt heavier than it should have. Heat clung to the rows of seated students like sweat under a uniform. Fluorescent lights buzzed quietly overhead while the principal's voice echoed through cheap speakers, delivering a speech no one really listened to. It was graduation—but it didn't feel triumphant. Just stretched, like time itself was waiting for something else to start.

Mizuki stood at the edge of the stage, arms folded, eyes scanning the crowd like a sentinel. She didn't smile. She rarely did. Every year, she watched students march out into the world thinking they knew what it meant to survive. But this year, something about the silence between words unnerved her. She checked the side doors more than once.

Ayane sat toward the front, hands folded too tight in her lap. Daisuke whispered something to her—probably a joke—but her laughter never came. Her gaze remained fixed on one point, blinking as if to hold something back. From behind, Reina leaned sideways in her chair and clicked her tongue.

"Oh my god. I swear if this speech goes on another five minutes, I'll throw myself out a window," Reina muttered, loud enough for half a row to hear. She pulled her phone out for the fifth time, sighed at the lack of signal, and snapped her gum in frustration.

Further back, Hana fidgeted next to Riku, her hands pressed between her thighs like she wanted to be anywhere else. Riku said something low to her, but she didn't respond. Her eyes were somewhere else—on someone else. Still, she leaned toward him a little more, maybe just to pretend.

And then it happened.

A scream. One of those high, slicing ones that rips through the air and silences everything.

All heads turned toward the gym doors as another scream followed—and then another, lower, wetter. The doors burst open, and two faculty members staggered inside. One collapsed. The other had blood on his face and shirt—his mouth. His mouth was still chewing.

Students screamed. Some ran. Others stood in place, paralyzed. Mizuki reacted instantly, rushing toward the entrance. Her voice was sharp, cutting through the chaos: "Everyone stay back!"

But it was already too late.

The infected teacher rose from the floor, blood trailing from his lips, and pounced on another staff member at the back. The screams doubled. Chairs flipped. The crowd broke.

Ayane clung to Daisuke as the front row scrambled. "We need to move," she said, voice high and panicked. "Dai—we need to go, now!"

"Shit—where—how?!" Daisuke pulled his bag forward, nearly dropping it as he dug for something. "There's an exit near the west stairwell—if we can just—"

"No, the hallways are already filling up," Mizuki barked, pushing her way back toward the group with blood on her sleeves. She motioned toward the emergency exit near the side wall. "Move now. No questions."

Reina kicked her seat over and spun toward the exit. "Screw this! I'm not dying in a goddamn gym!"

Ayane hesitated, pulling Daisuke after her, her eyes scanning the chaos—searching for someone not at her side.

Hana grabbed Riku's wrist, knuckles white. "Where do we go? What do we do!?"

For a second, all eyes swept toward the same direction—toward the few who hadn't frozen. Among them stood someone who hadn't moved, hadn't panicked. The kind of person others might follow.

Riku didn't flinch. His breathing was sharp, but his mind was moving. He looked once at the crowd, then toward the stairwell above the gym's rear bleachers. His voice came steady, louder than anyone expected.

"North stairwell. To the rooftop," he ordered. "Lock this gym behind us. Block the doors with the chairs. We get up high and regroup."

Mizuki's eyes flicked toward him, measuring. She didn't argue. Reina looked like she wanted to, but didn't. Ayane nodded once, tears running but legs steady. Hana still clung to him, whispering things no one could hear.

And for just one moment—amid the screams, the blood, and the cracking bones behind them—someone was leading. Riku was in front.

And graduation was officially over.

About

Graduation Day was supposed to be the end of an era. The ceremony was supposed to be beautiful. One last goodbye. One final photo. A beginning.

Instead, it became the start of a nightmare.

It only took one scream. One bite. One heartbeat too slow.

Then it was chaos.

You watched your school turn into a slaughterhouse. Blood on the gym floor. Desks overturned. Teachers fell first. Students followed. Within minutes, the school descended into chaos—teachers turned, students devoured, doors locked. You were there. You survived. Barely.

This isn't just a zombie outbreak. It's every secret they never said. Every kiss that never happened. Every touch that now comes too late.

Desire. Regret. Betrayal. Survival.

All twisted together in a building that's falling apart.

And you?

You were supposed to graduate today. Now, they're asking if you'll be the one to put a bullet between someone's eyes.

Not because you hate them. Because you're the only one who can.
