Broken Clock, Mended Hearts
Haruto Takayama never cared much about history, old school clocks, or stories of things lost in time. All he wanted was to find his missing sister, Ayumi, who vanished a year before with no trace. Sometimes he blames himself; he sometimes wonders what he missed or if he could’ve saved her. Would you go back into your worst memory to rescue someone you love?
Under the rain at dusk, Haruto stumbles into the city’s abandoned train station. His night is changed by a strange gray-haired girl named Sora, who claims she can “see leaks in time.” Her warning is direct: “Your past isn’t as trapped as you wish.” Her eyes flicker with colors he can’t name, and she pushes a strange, gear-shaped token into his hand. The air shudders.
Sora takes Haruto on a hurried walk through frozen moments in time: a festival in 1985, a war drill, his own lost eighth birthday. She pulls him before glimmers of the past with urgent speed—someone is watching them, her words say, and these time cracks only stay open for a short time. He sees Ayumi in flashes, always out of reach. Sora won’t explain the details, but she seems hurt by what they’re doing. Does she carry loss too?
The Station Watchers close in. Strange men in long coats, faces blurry in half-memory, chase their trail. Sora shouts, “Choose one! Go back or lose her forever!” Time splits around Haruto. He remembers Ayumi screaming his name in an alley, the night she was lost. Heart pounding, he plunges back. Sunlight, then black. 
He finds himself a year before, behind his childhood house. Ayumi runs down an old alley, dropping a red scarf. Child-Haruto is ahead, confused and scared. Sora stands behind, her form unclear, already fading. “One change,” she whispers, “no more.” If you could fix one thing, even with risk, would you dare?
Haruto rushes after Ayumi. He stumbles, calling her name. The air twists. A Watcher slips toward them—he recognizes the face as his old principal, but twisted and wrong. Ayumi turns to look at what frightens him, and Haruto intervenes. Instead of letting fear win, he takes her hand. Time ripples, barely holding. Ayumi clings to him. “I thought you let me go,” she says.
The risk unfolds. Flashes of other choices taunt him—other presents, other regrets. Sora appears a final time to warn, “All change steals something. Choose your memory. Let what is lost be lost.”
Child-Haruto hugs Ayumi, and the Watcher vanishes, leaving only a feeling of smoke and drift.
When Haruto stirs, he wakes in the train station. Sun breaks over the tracks. Ayumi stands near, reading her old comic, wearing her red scarf. She meets his eyes. “Did something change?” she asks softly. He can’t find Sora. He never saw the Watchers again. Yet when he glances at his hand, the old gear token has cracked. 
As Haruto walks away with Ayumi, unsure what changed in the world around him, rain falls in thin lines over the town clock. Its hands move backwards, just for a moment. Where did Sora really go? Does changing one wound in time always fix another, or does it make newer scars?
The last shot lingers on the broken token, now faded, resting on an unmarked grave in the rain. Fade to black.
