Shards of Astra: Expedition Into the Mirror Forest
It’s autumn when Kaito Yamura joins Nova Search, an exploration group famed for entering forbidden places. His reason? He wants to find his sister, who vanished on an earlier team, two years past. Few talk about what happened, but whispers haunt the team’s camp: “No one should look into the woods at midnight.” Do you wonder what he’s risking for those answers?
Kaito’s team holds four odd souls. Rio’s voice shakes when she pulls out old maps. Jiro will crack a quick grin, but keeps an eye on anyone new. Tomo, quiet by day, turns sharp when trouble’s near. Old Guard Captain Miya, scar on her left eye, only tells stories rooted in loss. They argue before dawn breaks. Why send new people, why send Kaito? He listens, curses soft, and slips his sister’s old charm into his shoe.
Mission: cross the Mirror Forest, past its heart, and decode the stone which no Searcher in the last decade’s managed. One problem: the old radio signal—Astra call sign—that blipped near the lost trail late last week. Kaito tells only Rio: “That was Hina’s voice.” Rio breathes out, shoulders rigid. She won’t question if he’s right.
Maps fail midday when silver fog laps boots and blankets needle-like trees. Jiro shakes a glowstick, light flashing off the thick ferns. Something moves in fog, drawing arcs Kaito swears only his sister would walk. There’s almost a song under the hush of wind, is it the same one from two years before? 
Team faces tension fast; supplies don’t match tracks—someone’s hand-stitched mark turns out to match Kaito’s sister’s old way markers. Flashback: her fingers brown from bark, deft and sure. A ringing sound splits night briefly. Do they camp, or run onward? Tomo votes for moving; Miya’s hard line “Stay” prevails. Who do you think would push to keep going?
Later, Rio finds a loop in the map: their path brought them in a vast spiral, always returning to the same knotted willow shaped like a hand. Heads grow thick with doubt. None can deny someone—something—is shifting the land around them. They whisper all night, sleep is a blanket full of knives.
Past midnight, Kaito’s charm heats up. Voices hiss in hush: a relay of speech deep within the woods. Hina’s locket falls out of his bag. He follows a gleam and glimpses a shadow he once called family. “Kaito? Don’t let go,” the figure pleads, but the woods snap it back. Kaito stumbles, grabs thorned vines, draws blood as proof this is no lie. 
Morn comes harsh. Trails fade and temps drop, marking frost on their boots despite the season. They argue bitterly, hunger and fear biting deep. Miya reveals a story—the Mirror Forest was said to be a test made by old Servants of Astra, meant to cull the faithless and return only those who belong. She knows, for half her squad never left this wood. “But you can walk out.” She aches behind the words.
Kaito and Tomo clash: Kaito wants to listen to forest “signs”, Tomo says trust facts, not hope, but Jiro catches the path only when he lets Kaito guide them by the old charm. Rio protects him, wary, whispering: “Don’t leave us, please.” How would you vote? Facts, faith, or both?
Nights lengthen as they track odd glyphs made from boots and bare feet and childlike scrawls (Hina’s script). Suddenly the group comes to a stand of mirrors nailed to trees, hundreds, none the same. Jiro touches one and screams—he sees a shape in the glass no one else can. They crowd in tight, and the glass fogs up, showing not their own faces, but visions from each one’s worst hours. Rio drops to knees, shaking, Miya lets out a sound like grief, Tomo throws up a quick prayer. 
Kaito finds a clue. One mirror is both cold and burns at the touch: behind it, in shadow, is a door-sized slit in the bark. He slips through first, as the others shout. He finds a grove beyond, where the air is sweet but freezing checker-light fills his lungs. There stands Hina—or at least, the girl wearing Hina’s smile. She croons: “Looking for me, little brother?” A field of floating stones forms around her.
This isn’t a reunion. But something in the stones matches drawings Hina left in their home years before. As the team forces their way into the grove, tempers fray. The last words of the episode: Hina’s double points skyward: “If you want the truth, look for the shard with your name. But it will show what you don’t want.” As they step closer, each team member must face their own regrets made real, unable to run as the woods close behind. 
The screen freezes—Kaito’s reflection crackling, Hina’s laugh low and bitter, while thunder shakes the sky and splits an old pine. Which of them, same as before, will not make it back? Would you have dared to enter these woods at all?
