Akio didn’t mean to break the sunstone. That should be clear right from the start. He’s a sixteen-year-old with copper hair, living in the ash-choked outer rings of Tsukisato. Only a few even remember when the city glowed at night, fed by flame mages wrapped in legends and soot-stains. Most people now can’t spare the spit for a story. Still—when legend dust blows this close, you’d think someone would warn you not to poke it with your stick. Would you?
Yuki, nervy and curious, saw Akio trip as usual. Her laugh echoed weird off half-sunken walls. “One day, you’ll discover a tunnel to the moon,” she grinned, “right in a rat’s nest.”
Akio, grateful she never talks about the fire in his hands, makes a poor joke back. They check broken glyphs on the stone. The carving yawns. Something stirs. But in the flicker, a shadow mouth exhales—using Akio as a match.
After, nothing’s the same.
The sun rises, but only Akio notices daylight bending sick, heat threads shivering in the alleys. Magma-red marks curl around his wrists by dawn. Every step near metal, he sparks. Lan, their weary mentor with half a dozen stories and two working hands, pulls the pair into tomorrow’s mess. Akio burns when he’s scared; when Yuki’s close he stings less, but the world fades at the edges. Do you ever feel like the ground pulls you under, just to listen for a moment more?
But Yuki runs experiments. Hands in gloves, books stacked up to her chin, she clocks the heat-lash that gutters from him each time Akio breathes deep. Her own trick—cold, silver, the taste of a coming storm—flinches as she works. She wants to help him control it. She wants to see where it breaks, too. Would you trust her not to push?
A knock—no, a whole boom—takes the roof half off at midnight. Flamewatch comes, black armor flickering, borrowed from better days. Something’s pulled an old heart from the deep mines under Tsukisato, and the city’s lights hate the dark. Their captain, Tamari, offers one ugly deal. Either the pair work for her, and show what the stone did—or they vanish soon as dawn.
Akio doesn’t want to run. He wants to be useful for once. Yuki decides in her sleep: they take the job. Before sunup, they crawl down a seam in the city where heat warps the clay itself. Glyphs crackle. An echo answers Akio’s every pulse. The secret: whatever’s inside the sunstone wants out. Now it calls to things that shouldn’t wake, even under tons of dirt.
Down deep, the air bites at their skin. Lan limps after, short on patience but rich in lore. He walks first—his tales twist to explain nothing, but his frowns always mean danger. They see bones set in black glass, strange twists where the magma marks climbed once, and old script scrawled across the remains: Watch the sun, or watch it drown you.
The deeper he goes, the more Akio shakes. It isn’t just fear—there’s a feeling, rich and bright, that the thing in his veins could break free or sweep them all away. Even Yuki hesitates at the core. Lan spells their names against the heat. Will it be enough?
The last door calls for Akio’s palm—not Yuki, not Lan. It cracks as he breathes, voice shaped only by fire. The thing behind the door? It laughs—a single word, not quite human. It knows Akio. It knows, and it’s hungry.
Fade out on lanterns stuttering. Something peaks out from shadow, gold eyes alight, ready to step forward.
If you stood in their shoes, would you open that door, too? Or is it enough to wonder, sometimes, where flame comes from at all?
