The Mist That Forgets: Survival Mystery at Ryuuwa Pass
Introduction: Vanishing Paths
They all saw the sign at the start. Ryuuwa Pass, keep out by law, chain-link fence rusting into the mud. Why would a group of classmates get near this side of the mountains on the last day of summer? Curiosity pulls harder the less you know.
Yusei Kurogane, third-year at Akei High, wanted answers. Not just about Ryuuwa’s lost hikers or strange local tales, but about his own sister, Mai. She vanished here two years back. They called it an accident, but the search teams left her case alone.
“It’s just for one night. Camp, see if we find any real clues,” Yusei tells Haruka, who lugs her worn camera everywhere but looks like she’d rather run. “I’d never forgive myself if we missed the smallest thing,” she answers, chewing her lip.
Main Cast Steps Forward
Six people enter.
Yusei: strong, guarded, always thinks things through before he jumps. Haruka, the friend; Jun, quiet ace, always keeps a map on hand; Teru, energetic, jokes until the fear sneaks in; twins Michi and Motoki, clever but competitive.
At dusk they slip past the fence. They hope to track, film, push deeper than adults ever could—teen logic is sound, in its way. Their breath sticks to cold in the air. Are they scared or excited? Is it both?
The story leaves only faint prints behind them: half-remembered songs about fog, silenced warnings, local talk about people who come back with new scars on memory itself.
Entering Unknown Ground
The trail seems normal for the first hour. Sun sags and fog rises quick, white, thick as wall. Shoes wet, socks scratchy, cell signals gone.
Teru laughs. “Is this all they’ve got? Spooky mist?”
But the forest shuts out every other sense, brings horror with calm. Tweets, cracks, the air tastes like old bathwater. Are you a forest fan or did you get lost as a kid? This place feels both present and gone. Leaves stick to lips as Michi mutters—”The map’s—wait. This isn’t it.”

Locked Into the Fog: Patterns Break
Night falls. They build camp near a granite outcrop; fire smokes brown. Haruka backs away to record, lens focusing—she snaps the first photo of the night. Later, back at firelight, she can’t remember taking one of them. Both twins there, but in Haruka’s photo, only Motoki sits by Yusei.
Sometimes, a story changes with what doesn’t show on film or in mind. Next day, Yusei searches the group’s talk. Why’s nobody counting their bags right? Jun checks the map—there’s a fork where none is drawn, and the footprints double back. Will most teens notice? Jun does. “Why did we sleep two nights?” Jun asks. But only four replace the start’s six. Nobody grieves who’s lost. Memories fade as fast as words can carry.

Memory as the True Hunger
Dawn should bring hope, but these teens wake afraid they woke. Some names fall from tongues—half-real, half-missed. Their notes in Yusei’s book fade, smudged. “Did we come here for something?” Teru cries at noon, voice cracked, as if hearing first frost split grass.
Only Yusei feels the shape of loss. Even he can’t look at his own sister’s name now. All signs point back to Ryuuwa’s hunger: the pass takes not lead, not skin, but belonging. What feeds this thicket’s thirst? Mist closes, hushes steps behind. Did you ever wake and worry that a dream had stolen someone from you? Some things can’t be recalled into light.

Pushing Beyond Fear
Yusei takes hold of Haruka—a feeling shocks through bone, solid, the first thing real. Together they race for any way out. There’s a lake that must ring true or false, marked nowhere, slick black-like mirror glass. Trees twist in pattern.
Jun says, quietly, “If you call out for someone who isn’t there, and they don’t answer. Do you try again?”
Nobody answers, because who is left? Some faces lost to blind spots, shadows turn to absence at their backs.

Cliffhanger
Mid-stride, the edge collapses to void. Yusei sees Mai’s coat hanging in a tree, years-old and fresh. Haruka screams, pointing not at the coat but at footprints fanning out, a ring in the soft moss. Are they leaving? Or arriving?
Last thing: the sun’s light cuts, burns the fog off even as the shadows close on Yusei’s hand. He snaps, blinded, staggers—and hears a name on a lost voice behind him. He holds Haruka’s camera. But who is holding him?
Who, in your own dreams, would you cling to if you weren’t sure you still knew their name?
