The city of Niyama feels different today. Kaito Yamada, an average third-year high schooler, is up early for exams. He always leaves home with two things: his silver lucky coin and his wish to talk to class idol Saki Fujimura. But minutes before his train arrives, he locks eyes with a whiskered stranger—an odd calico cat, poised on the edge of the old stone bridge.
“Hey… You again? Brave little guy,” Kaito mutters. He often sees this stray, always darting past on the way to school. This morning, though, the cat cries—a hollow, long meow—and doesn’t move. Kaito steps closer. That’s when he spots the voice memo recorder tied around its neck. Someone must have put it there.
Curious, Kaito kneels, reaching towards the cat. “Let’s have a deal,” he jokes, then presses play. The recording is scratchy: “If you found this, please help me. Follow the cat for luck.” Kaito chokes, unsure if he should laugh or worry. Would you keep following a mystery thread if it meant you might skip the most important day of your youth?
The cat darts away. Kaito follows. It leads him on winding routes away from the train, through forgotten alleys, busy market stalls, even a quick shortcut across an empty kids’ park. Unwilling to lose it, he barely notices the clock ticking by. Meanwhile, his lucky coin falls from his blazer pocket—but he doesn’t see. 
Suddenly, Saki and her best friend Midori cross paths with Kaito. “Yamada-kun? Why’re you chasing that cat?” Saki asks. Her curiosity catches him off-guard. With a bashful grin, he explains about the message and the promise of luck. Saki, always game for something wild, insists she’s coming along—Midori groans but tags along too. It’s a race, now.
Meanwhile, in a cramped apartment near the river, shy first-year Ren Okabe wakes from a nap to discover something’s missing—his late father’s coin, the only keepsake left. Despair hits quick. Across town, Kaito’s day is full of near-misses after losing his own lucky coin, but he starts to think the world’s handing him slip-ups on purpose.
Chasing the cat soon becomes a group journey. It slips through construction sites, climbs store roofs, forces them to help a lost child, and finally sprints toward a small clinic with busy workers outside. Here, the calico curls up by a bench beside a tired nurse—a familiar face that Saki instantly recognizes. “That’s Aki, my cousin,” she calls out.
The gang scrambles over. Ren, flustered, races towards them too—news just broke that his lost coin ended up here somehow. The lucky coin swapped pockets: Kaito’s landed near where the cat led them, while Ren’s travels have brought him to the same point. Both stare at the coins, realization dawning.
“Luck shifts hands, huh?” Saki quips with a sly wink. Not a minute later, an announcement blares—a train delay saves Kaito from missing his exam window, and a child’s worried mother is found thanks to their help earlier. Did luck really weave all these threads, or were choices more vital?
The cat, unconcerned, jumps into the dusty wildflower patch and stretches out for a nap. But as our friends leave, it sits up, tail swishing. Its eyes catch Kaito’s, sharp and knowing. In that moment, did you wonder if fate has fur and a purr? 
Tomorrow: scraps of threads, trails, and fresh winds in Niyama city. There’s still no knowing when the lucky cat—and a day full of twists—will cross their paths again. But tonight, as dusk settles, Kaito feels change in the air. The cat vanishes into light, leaving only a faint pawprint under the fading sun. 
A single, scratched new recording is found under the bridge as the credits roll: “Luck, given and taken. Tomorrow runs on chance. Are you ready to trade your luck for a wish?” Clocks tick. Will Kaito risk it all on another day?
