Prologue: Waning Light
Night covers Amasai Town. The school clocktower’s bell rings deep. Yuto Ayazaki walks alone with heavy steps, hands tucked in his pockets. He just hit seventeen last week, but guilt drags him down. He still can’t shake off his brother Ren’s accident four months ago. Do you ever feel stuck at one spot while the world keeps moving?
Act I: The Key Turns
Yuto’s phone vibrates. It’s his lab partner, Isumi. She says, “Yuto, you’ve got to see this.” Excitement cracks her voice. In the physics lab, an ancient brass watch rests under the lens. Runes glow on the surface. Isumi hands Yuto the watch, whispering, “What if this is the real thing?” Yuto scoffs. Still, he gives it a wind. Light leaps out — the world shakes. Suddenly, the lab’s gone; in its place is the schoolyard from one year ago. A strange feeling sets in but nobody notices him. He sees his younger self, laughing with Ren.
Act II: Retreat and Replay
Stunned, Yuto scrambles to find Isumi, but no such luck. Only Ren walks by, humming. Yuto tries talking to him. Ren laughs. “Strange new club?” Yuto stammers, tempted to shout the truth, but the watch burns his hand. Pulse racing, he hides his shaking hand. “Could I warn him? Save my brother?”
Act III: Threading the Needle
Day after day, Yuto trials plans to push Ren away from his date with fate. Sometimes he tips off the teachers. Sometimes he sends strange texts to Ren’s phone. But every time, something twists fate back to what’s written. The clocktower in the edge of the yard points right to 5:37 pm — the time of the crash. Some days are bright, others bleak. Yuto’s hope thins. Is Time itself against him?
Case Study: Akane’s Folly
He finds Isumi — or rather, her First-Year self. She doesn’t know him yet, but helps him hack the school camera systems. Her sharp words sting, “Are you planning something stupid?” Yuto wonders, can he trust the past to fix his pain?
Act IV: Fracture
Yuto sneaks a message into Ren’s bag: “Don’t cross the street today.” But Ren ignores it. The day spins out of control instead. The brass watch starts breaking; cracks spider across the face. Yuto screams into the wind as Ren’s voice calls away: “Don’t worry, you did your best!” Did he really?
Honestly: True Stakes
Each ripple brings subtle changes — missing lockers, altered posters, a friend’s laugh out of order. He meets a future version of Isumi, streaked silver hair, frown sharp. “You’re running in circles. Are you trying to save someone, or are you just afraid to lose?” Yuto drinks in those words, mouth dry. Why do we try so hard to turn back the clock?
Act V: The Choice at Dusk
As dusk falls, Yuto overwrite one last chance. He shouts to Ren from across the street. Ren pauses, eyes wide, confused, but then steps. Yuto grabs the brass watch, twisting it open. In a burst, both are dragged through swirling light. The clocktower tolls; time freezes. Yuto faces the world where he never existed at school and Ren walked alone.
Cliffhanger: The Next Turn
The world’s colors smear, people walk by but no one sees Yuto now. Not Ren, not Isumi, nothing fits. He’s outside the running clock. Ren’s voice echoes from the middle of it all — “Who are you…?” Before Yuto answers, shadow jumps from the clocktower onto the plaza. A hooded girl with the brass watch steps forward and grins. “Want to trade places?” Where would you go, if Time cracked open?
