Tsubasa Nanase stars as our sharp and nervous hero. He craves answers about a letter left by his granddad—someone nobody wants to talk about. Each line just hints at hidden places, cups of old tea, strange coins, and something about ‘Be prepared when gold calls your name at dusk.’ Strange, right?
His buddies Maya (nosey, street smart) and Sora (quiet, loves books) don’t get it right away. Maya asks, ‘Is this just some prank letter, Tsubasa?’ Sora flips through notes. ‘I’ve seen tales about ancestor puzzles,’ he says. ‘But no, this code’s fresh.’
After a normal school day, the group sneaks into the old park on the hill, building their hunt around every word. Shadows stretch across rusted swings. Sora leans low, ‘Sun’s going, dusk’s key to the next clue, you think?’
What would you search for first? Is your gut screaming tree roots—or weird corners by the gate?
Old benches come into play. Maya arranges sticks and finds a line of tiny scratches. Tsubasa’s finger fits inside a notch, sending a puff of red dirt up. ‘That was not just a guess,’ he says. Their next clue speaks straight to them—‘Face your shadow at dusk. Count seven steps behind what’s forgotten and broken.’
They count the steps from a smashed fountain, hit a lone stone with letters so faint it’s almost gone. Sora traces his phone light over it until Tsubasa says, ‘That’s… my granddad’s mark.’ Whose family hasn’t tucked secrets away in odd spots?
Laughter echoes when Maya stands on the stone by accident. But no time to pause. Across the path, a dark shape slips away—someone else is watching. The mood gets tighter, careful, unsure.
Rusty wire lines the maze’s edge. But only by dusk does the right shape appear: a ring of bricks set like the letter O—just as the clue warned.
Sora says, ‘We need to work, not fight.’ They gather at the center. Tsubasa’s worry slows him. ‘What if there’s no treasure? We’re just chasing nothing?’
Maya claps him on the back. She says, ‘You call that nothing?’ She dumps a clutch of blue-green stones into his palm. Chipped for sure, but not trash—Maya says, ‘That’s glass. Ancient, see-below-the-scar dirt glass.’
Nerves rise with crunching steps—another person looms at the entry to their ring. Tsubasa whispers, ‘Stay close…’
Unknown until now, another would-be hunter has shown an interest. But the deep red scarf, the key-shaped necklace, all point at an old after-school classmate—Yui, cold and sharp.
Yui says, ‘Well, you cracked most of it. Just one piece left. Want help or a race for the last riddle, Tsubasa?’
The game peaks. To trust, or fight? One last piece shines in the red dusk. Will the answer change the friends—or break them? The final clue—a wallet-size metal box tumbling from the roots. Tsubasa lunges, but so does Yui. The box teeters between hands.
Your heart stops.
‘Stop!’ Maya yells. One foot slips. Dusk swallows what’s left of the light.
To be continued.
