The episode opens on a windless morning, shrouded in pale light. Taro Nakajima, a seventeen-year-old apprentice storyteller, stares at the edge of the ancient Lacuna Grove. He tightens the faded blue cord around his wrist. ‘Last chance, Taro. Are you sure about this?’ asks his best friend Mika, waiting nearby with her sketchbook half full. Taro nods, chest tight. ‘I need to find my brother’s voice.’
Mika steps ahead first, crushing dew-heavy grass. For a moment, you might wonder: how would you feel, stepping into a forest where tales sleep? Each legend in Lacuna Grove has become real, pausing only when no one remembers their story. Some wait to be told again. Some have grown wild in their forgetting, like vines left untended. A darker intent flickers in the gloom; who wakes the forgotten beasts?
Taro’s hope digs wide. His older brother Masato vanished three years ago, after slipping into the grove with nothing but a charred book of sun-faded fables. Taro’s goal: walk deeper than anyone has dared, past willow-lash rivers, until he finds the truth. You’d do the same for family. Or would you run?
Taro, Mika, and Sumi—the local shrine apprentice—push deeper. Sumi keeps counting temple beads, lips moving in old songs. It’s not much comfort. Something about her eyes says she’s seen what others don’t. ‘The grove doesn’t like lies,’ she warns, voice thin. ‘Speak only the truth, ever.’ 
An hour in, spirals of blue mist coil at their ankles. Their own names thrum back at them—tiny snarls, echoes in the dusk-bright shade. Sumi pauses, throat thick. ‘If you hear your mother call, don’t answer. That means it’s already too late.’ Taro swallows hard. Maybe you’re thinking: I wouldn’t fall for something that simple. Taro tells himself he won’t, but his knuckles go white around his lamp.
The expedition hits its first kink near dusk. Three twisted pillars choke the trail, carved with spirals and names of heroes lost from songs. Mika sketches madly, shivering, hand cold—even though she’s not scared, she claims. ‘What’s in a name anyway? They’re just words,’ Taro tries to joke. But Mika shoots him a look. ‘Aren’t you here because words are power?’ And isn’t she right?
They camp under gnawed trees. Taro sits stiff, staring at the fire. Sparks crack upward, splintering light on each of their eyes, shadows twitching. Somewhere behind him, wind drags a low, soft moan. ‘It’s only the air,’ Sumi whispers, clutching her bead chain till red makes white round her knuckles. Do you ever let your mind go wild when your ears strain into night?
Mika draws runes in the dirt, searching the shapes for meaning. ‘Look here,’ she says, pointing at a spiral. At its middle, a hollow—faded, easy to miss. ‘If stories rot here, maybe so do lies.’ Taro leans in, hope scraping his gut.
Low to the ground, they hear the clicking, then see insect wings nudge aside a tiny book. Inside, pages are glued by sweet, amber gunk. They know it’s fable sap—rare, dangerous, able to wake soulbound tales left locked in myth. Taro touches it and reels—across his vision: his brother’s hand holding the same sap. ‘Masato!’ he gasps, but the vision flashes cold, gone.
‘That’s not real,’ Sumi snaps, voice rising. ‘The Grove twists memories for those without courage.’ But doubt worms in. Isn’t this a clue? Mika drops her lamp, nearly sputters, cinders no wider than fingernails leaping in her eyes. Taro grabs her arm. ‘Stay calm. We’re here for stories, not phantoms.’
The group presses on. They break through birch thickets to a stone pond—a mirror lake—curled inside ring-rooted trees. Every water drop holds a story, forming faces of forgotten gods. Or so Mika claims, pen sketching, arms shaking. 
‘Why do we believe what we hear if truth slides like mud?’ she mutters. Fair question—or is it?
A sudden hush cuts birdsong—a woman’s voice, soft, pure, calling, ‘Taro, come home.’ His chest buckles. He leans near the pond’s skin. ‘Mother?’ But both Mika and Sumi hiss, ‘It’s not her.’ Riven between longing and resolve, Taro holds back.
Near the grove’s deep heart, giant roots arch over their path. Taro, breathing rough, finds a bone-plaited charm, Masato’s sigil. Is he near? The roots shed flakes of burning blue light. Sumi stops, afraid. ‘The story’s heart lies past those, but not all who enter leave the tale. Are you sure, Taro? One step, you lose your way.’
He answers, thin: ‘I can’t go back.’ They press onward. 
Soon, memory-mist overtakes them. Tall shapes of tales half-told stagger past on bent legs—beasts stitched of folk song, charm dolls with faces forgotten. They pass two moaning shadows baring their empty faces, hands outstretched like hooks. Mika screams, turns to run, and the yellow eyes of something ancient widen, old as story itself. Did she survive? Taro grasped at her arm. But then—he only feels wood, constellations of moss, nothing but empty air. ‘Mika?’ Darkness swallows the answer, splitting the group. 
The episode closes on Taro, pitched into a shivering dusk under the biggest willow. He calls into the hush, voice keening. Is the shadow that circles him a friend—or something that’s been waiting centuries for just this? The grove is alive, and now, everyone inside must finish a story. The camera pulls back. You’re left staring down a single question: how strong is your thread to things—or people—you’ve lost?
Next time, Taro must bargain with memory itself to save his friends—or erase what’s left of his own tale.
