It was in the deep night at the end of May that Spice finished his artificial snow crystal.
Inside the old cooling unit set at the center of the workshop — a compressor scavenged from a city data center and rebuilt by Spice’s own hand — a perfect hexagonal crystal of ice was growing at the tip of a thin copper wire. Temperature: minus fifteen degrees. humidity : ninety-three percent. The figures were displayed one by one on Spice’s handmade monitor, but his eyes were fixed on the crystal itself, more than the numbers.
Its six arms formed a perfect symmetry . From their tips, even finer branches spread out in a radial pattern.
“…This is it.”
Spice murmured . As if confirming something, he glanced once more at the monitor, then brought his gaze back.
The problem arose the next morning.
When he stopped the cooling unit, the crystal — which should have melted in a matter of seconds at room temperature — showed no change at all, even in the workshop’s twenty-two-degree air, scented with mint and old oil. Spice held up his instrument. Temperature: normal. Humidity: normal. There was no data at all to explain the crystal’s continued existence.
Kopo peeked into the workshop just past noon.
“You’re making something weird.”
“Don’t look.”
Spice immediately blocked him with a hand. But Kopo had already caught sight of the white hexagon at the tip of the copper wire.
“…Does that not melt?”
“It doesn’t melt.”
“Why?”
“Don’t know. No data.”
Kopo, unable to quite process Spice saying “I don’t know” — something he rarely admitted — left the workshop.
He brought the matter to Sonchō that evening. The elder, tilting his top hat beneath the weeping cherry while nibbling on a sakura mochi, held the crystal Spice handed him without even using his glasses, and gazed at it silently for a while.
“Feh-feh. …This is one still waiting for its reply.”
“Reply?”
“Snow is a letter sent from the heavens. Some scholar far to the north said so, long ago. …Though a letter can either be waiting for a reply or not. This one, I’d say, is the former.”
Spice said nothing. Back in the workshop, he held the crystal up to the light. Its six arms, each at a perfect sixty-degree symmetry. What temperature and humidity had shaped this form could, in theory, be calculated backward. Which meant this crystal was, in effect, a record of the “sky it was born under” — and yet this crystal had been made artificially, by Spice himself. A sky it was born under shouldn’t have existed at all.
At dawn on the third day, the crystal vanished.
Nothing remained at the tip of the copper wire. Spice checked his instrument, opened his notebook, wrote something down, and closed it quietly.
No one in town knows what was written in that notebook.
Margin note: The next morning, frost in the same hexagonal shape as the vanished crystal had spread across the inside of every window in the workshop. Spice pressed the shutter . But the instant he did, the frost vanished without a trace.
【Core of the Tale】
- Phenomenon used: a new phenomenon , “the heavens’ reply” — an artificial crystal with no sky of its own birth manifests , carrying a “memory of place,” and vanishes the moment its recipient recognizes a reply. Only the recipient ever knows the content of that reply.
- The story’s hidden theme: the boundary between what science can explain and what it cannot lies outside the instrument.
