There were six of us when we went in. Only five of us agreed on what happened next.

---

Aiko sat in a white waiting room and tried to figure out which of the five strangers she'd been locked in with was most likely to bolt first.

The facility was somewhere outside Sapporo, in a part of the prefecture that didn't appear on civilian maps. A woman in a grey blazer had given them tablets and water bottles and a speech about civic responsibility that none of them believed but all of them needed to hear, because the alternative was thinking too hard about what they'd agreed to. "The Trial Layer is a modulated environment designed to stress-test interpretive frameworks under controlled conditions," the woman had said, smiling like the words tasted fine to her. "Your coherence will be monitored. The data you generate will contribute to the National Coherence Project."

Nobody asked what that meant. Aiko noticed.

She'd signed up to test how people disagreed. That was the version she trusted. The rest — the jargon, the monitoring, the way the woman said *coherence* like it was a grade you could fail — she filed under *things they're not telling us*.

She was good at noticing — it was the thing she liked least about herself. The boy with close-cropped hair hadn't stopped scanning the room since he'd entered: doors, walls, ceiling, doors again. The girl across from her had somehow rearranged all of them into a loose semicircle without anyone realizing they'd moved. The kid on the floor was taking apart his tablet's operating system like it had personally offended him. The quiet one in the corner was watching *her* notice everyone else. And the boy by the far wall was telling a story about a fireworks festival to anyone who would listen, his voice carrying the specific warmth of someone holding a memory so tightly they'd started to wear it smooth.

The boy with the exits was closest to her. She turned to him.

"You've been counting the exits."

He looked at her. Not startled. More like surprised someone had been paying attention. "Three doors," he said. "One's locked from the outside. The ventilation ducts are cosmetic."

"You checked the *ventilation ducts*?"

"My dad was an engineer. Structural assessment." A beat. "Before the restructuring."

He said it flat, the way people talk about things that used to hurt and now just define them. Aiko filed it. She understood things that defined people — she'd spent most of her life trying to read them, because if you could understand what someone meant, you could keep them close. That was the theory. In practice, understanding people hadn't stopped her brother from moving to an enclave she couldn't visit. Hadn't stopped the look on his face when he'd told her they just *saw things differently now*, as though that explained a locked door.

It wasn't disagreement anymore. It was something else. Like they weren't even in the same version anymore.

"I'm Aiko," she said.

"Ren."

Across the room, the girl — Mika, Aiko would learn — had Taro deep in conversation. He was mid-sentence about the festival: "—and the colors hang in the air for this impossible second, like the sky is holding its breath—" He stopped. Corrected himself. "Actually, I don't remember if it was the colors or the sound that came first. I always get that part mixed up." He laughed, but his hand tightened around his tablet. Mika saw it — the knuckles going white, the laugh not quite reaching the grip — and said nothing. She just moved closer, as if proximity could hold the crack shut.

Sora sat on the floor with her legs crossed, fingers moving across her screen with the focus of someone who'd already found something she wasn't supposed to find. She hadn't told anyone.

And Kai sat apart, watching. Not antisocially — more like someone observing a game he hadn't decided to join yet. When Aiko's eyes met his, he didn't look away. He just acknowledged it, like a fact being entered into a ledger.

---

The crossing took eleven seconds and lasted forever.

One moment they were standing on a platform, the hum of industrial cooling filling the room, the light flattening into something without a source. The next moment the room wasn't a room anymore. The walls dissolved — not dramatically, not with light or sound, but the way a dream dissolves when you realize you're dreaming. The floor became soil. The ceiling became sky. The air tasted different: wet, electric, alive in a way that had nothing to do with oxygen.

Taro grabbed Mika's arm. Mika let him.

The Trial Layer unfolded around them like a landscape deciding what it wanted to be. Hills rose and smoothed themselves. A forest assembled at the horizon, tree by tree, each one slightly different from the last as though the system were iterating on the concept of *tree* in real time. The sky settled into a color that wasn't quite blue — more like blue's idea of itself, oversaturated and humming at the edges. The wind smelled like rain but felt dry. Somewhere in the forest, leaves were making a sound that didn't match their shape — heavy, wooden clacking from things that looked like silk. Beautiful. Wrong in a way that was hard to articulate. Like a photograph with the contrast pushed one stop too far.

"Oh," Sora whispered. Then, louder: "Oh, this is *incredible*."

She was already walking toward the forest, her tablet forgotten, her diagnostic curiosity replaced by something older and more dangerous: wonder.

Kai followed her. Not toward the forest — toward a rock formation that had appeared to their left. He put his hand on it. Pressed. Watched the surface ripple faintly under his palm, as though the stone were deciding whether to be solid.

"It responds to attention," he said, to no one in particular.

That's when the companions arrived.

They didn't appear so much as *resolve*. Like something that had always been standing next to you, just out of the corner of your eye, finally stepping close enough to be seen.

Aiko's came first. It was small, luminous, vaguely animal — somewhere between a fox and a flame, with eyes that tracked her face like they were reading something written on the inside of her skin. When she reached for it, it leaned into her hand, and she felt a rush of something warm and confusing. Not thought exactly. More like being understood in a language she didn't speak yet.

Then it looked past her — toward Ren — and its expression shifted into something Aiko recognized with a sickening lurch. Longing. The particular longing of someone watching a person they're about to lose. She yanked her hand back. The companion blinked, recalibrated, and the expression vanished, replaced by something gentler and less specific. But it had shown — or almost shown — something she hadn't even admitted to herself yet. She glanced around. Nobody seemed to have noticed. She wasn't sure that was better.

Ren's companion was heavier. Dense. It sat beside him like a stone that had chosen to be an animal — compact, still, watchful. Where Aiko's companion radiated warmth, his radiated consequence. When it looked at the landscape, the landscape seemed to harden slightly, as though being observed by it made things more committed to their own existence. And when Aiko's companion had turned toward him with that longing expression, Ren's had gone rigid. Like a door locking from the inside. Ren hadn't noticed. His companion had noticed for him.

Taro's shimmered. It kept almost-solidifying into forms he recognized — a dog he'd had as a child, a figure from a photograph — then dissolving back into something translucent and searching. He kept trying to hold it, and it kept almost letting him.

Mika's orbited her. It moved through the group like a current, brushing against each of them, adjusting its shape to mirror whoever it was closest to. It had no fixed form. It was the space between people.

Taro watched it pass and pulled Mika closer. She let him.

Sora's was fractured. Multiple. A constellation of small, flickering presences that darted around her head like thoughts she hadn't finished thinking. Each one showed a different version of the landscape when she looked through it — the same hills, but with different weather, different light, different futures.

"Guys," she said softly, not looking away from them. "I don't think we're all seeing the same place."

Nobody answered. It wasn't the kind of thing you answered.

Kai's was the last to appear, and when it did, it stood behind him. Not beside. Not in front. Behind, where he couldn't quite see it, and it could see everything he saw. He didn't reach for it. He didn't need to. He could feel it already — not as comfort or understanding, but as leverage.

For a long time, nobody spoke. They just stood in the alien light with their strange new companions and felt the specific, unrepeatable vertigo of being somewhere that hadn't existed until they'd arrived to perceive it.

"We should probably explore," Ren said finally.

Taro didn't move. He was still trying to get his companion to hold a shape — any shape — and it kept slipping through his fingers like water that remembered being ice.

Aiko almost agreed. Then she looked at Kai — still standing apart, his companion behind him like a shadow that had chosen its own angle. He was watching Taro's companion cycle through forms, and his head was tilted slightly, the way you tilt your head when you're counting something.

She shook it off. "Yeah," she said. "We probably should."

---

They didn't realize how dark it was until they lost the clearing.

The trees closed in gradually, then all at once. Light filtered down in thin, uneven strips that didn't reach the ground. The air smelled like pine and something metallic underneath, like the memory of a machine. After a few minutes, it wasn't enough to see by.

"Nobody wanders," Mika said.

She reached back without looking and caught Taro's sleeve. He caught Sora's. The chain formed quickly — hands, wrists, fabric, whatever was closest.

Aiko ended up between Ren and Sora. Ren's grip was firm. Grounding.

"Stay close," he said.

"I am close."

"Closer."

She didn't argue.

They moved slowly. The ground shifted underfoot in ways that didn't match what they could see — roots where there hadn't been roots a second ago, dips that felt deeper than they looked. Their companions moved with them, dimmer here, as though the dark applied to them too. Aiko's pressed against her shin, warm but subdued. Not alarmed. Just — attentive. Ren's was the exception — it kept its shape, dense and forward, pushing ahead of him like it had already decided where they were going.

Something knocked ahead of them. A hollow, wooden sound.

They stopped.

"What was that?" Taro whispered. Beside him, his companion flickered between shapes — dog, then something smaller, then nothing recognizable — pressing tight against his leg like it was trying to hide inside him.

"Wind," Ren said.

"There's no wind," Sora said.

There wasn't. The trees were completely still.

The sound came again. Closer.

A shape in the dark. Low. Rectangular.

"Please tell me that's not a chest," Mika said.

Sora let out a quiet breath. Not delighted. Careful. "If this is a system layer…" She trailed off. Her fragments pulled in tight, close to her body.

"Don't," Mika said.

"Mimics," Sora said. The word came out like she'd been trying not to say it. "If the system generates based on interpretive frameworks, and we're all carrying game logic—"

"It's not a mimic," Ren said. "It's debris."

Aiko wasn't listening. She wasn't looking at the shape directly either. Looking at it made it settle, made it become something. Watching it off-center — just at the edge of her attention — kept it loose. Unfinished. Her companion had gone still against her leg. Not warm. Not urgent. Just *still*.

"Wait," she said.

Nobody stopped.

They moved closer. The shape sharpened as they approached — edges forming where there hadn't been edges, the suggestion of a lid.

Ren shifted his grip on her hand. "It's fine. We'll just go around it." His companion was already past the shape, waiting on the other side as though the question had been settled.

He stepped forward. Aiko's hand tightened on his before she knew why — a pull, half-conscious, like her body had registered something her mind hadn't caught up to yet.

And something happened.

Not clearly. Not in a way Aiko could describe afterward. A misalignment between where Ren was and where the dark was. A sound that wasn't quite right — not the wooden knock from before, something softer, wetter. And pressure. Brief, definite pressure against her palm through his grip, like he'd been pulled from the other side.

Ren jerked forward violently. The chain snapped.

His hand tore free from hers and he hit the ground hard, a sharp inhale that wasn't from falling. His leg kicked back once — involuntary, like shaking something off.

"*Fuck* —"

Aiko grabbed his shoulder before she thought about it, hauling him back. For one terrible second he didn't come — like the dark itself had closed around his ankle. Then he did.

He rolled onto his side, breathing hard.

There was blood.

It ran from his lower leg, dark in the low light, soaking through the fabric and spreading faster than it should. Mika dropped beside him immediately.

"What happened?"

Ren's mouth opened. Closed. Then: "I tripped."

"You're bleeding."

"It's fine."

"It's not — hold still —"

She pulled at the torn fabric. The cut underneath wasn't jagged. It was clean. Too clean. A single curved line across the back of his calf, deep enough to matter. He'd fallen forward. The cut was behind him.

Taro made a small, strangled noise. "What did that?"

"Nothing," Ren said. "I caught it on something."

Sora was crouched near where he'd fallen, her fragments flickering weakly. "There's nothing here," she said. The ground was roots and dirt. Nothing sharp enough. Nothing shaped like that.

Aiko stared at the space. She hadn't seen what did it. Not exactly. But she'd felt the moment before — the split second where something in the dark could have been one thing or another, and then wasn't either. And she'd felt the pull through his hand. That didn't feel like the ground.

"You didn't just trip," she said.

"Aiko." Ren pushed himself up. "I lost my footing."

"That cut isn't from a root."

"Yes it is." He tested his weight, winced, then straightened — too easily. The kind of movement that should have cost him more than it did. The blood had already soaked through Mika's makeshift bandage — a strip torn from her sleeve, pressed tight against the wound. He looked down at it like it was someone else's problem.

"I'm fine," he said. "Let's keep moving."

Mika started to object. Then didn't.

Taro glanced back at the shape one more time. His companion was still facing it — cycling through forms that didn't settle, flickering toward the shape like it was trying to remember something it had seen before. Taro looked away first. Looked at Mika instead, and something passed between them — not agreement, just a mutual decision to leave it alone.

Behind them, the shape sat in the dark. Low, rectangular, indifferent. If it had ever been anything more than debris, it wasn't now.

Or it had never been.

They reformed the chain. Hands finding each other again. Ren's grip was the same — firm, certain. But Aiko could feel the slight irregularity in his stride now, the weight favoring one leg, and the warm pulse of blood she could smell but he didn't seem to notice.

Her companion pressed against her shin. Not alarmed. Something quieter. Like a confirmation of something she hadn't quite asked.

She kept her eyes on the edges of the dark as they walked. Not looking directly. Watching the spaces where things hadn't decided to be real yet.

---

That night they made camp in a clearing the system seemed to have provided for them — flat ground, a ring of stones that functioned as a fire pit, though the fire Kai started didn't consume the wood it burned. The wood just glowed and radiated heat without degrading. Taro stared at it for a long time with an expression that suggested this bothered him more than anything else they'd encountered. The companions arranged themselves around the warmth in their own configurations — Taro's had finally settled into the dog shape, though it kept lifting its head and staring at the treeline like it heard something the rest of them couldn't. Ren's held its position at the edge of the clearing, solid and outward-facing, a sentry that hadn't been asked to stand watch.

Mika rewrapped Ren's leg by the fire. He let her, which surprised Aiko more than the injury had. The blood had slowed but not stopped. In the firelight the cut looked worse — that same clean curve, too deliberate for a root, too neat for a fall. Ren's companion didn't turn around. It stayed at the perimeter, facing the dark, as though the wound had nothing to do with it. Mika didn't say anything about it. She just tied the bandage tighter and moved away.

"Mimic got you good," Sora said from across the clearing. Light. Almost fond.

Ren snorted. "I tripped."

"Sure you did," Mika murmured, not looking up.

Aiko didn't laugh.

At one point, Kai stood up and moved to the other side of the clearing — casually, unhurried, as though he'd just felt like stretching. Three seconds later, a branch fell from a tree overhead and landed exactly where he'd been sitting. Nobody mentioned it. Aiko wasn't sure anyone else had noticed the timing.

The others fell asleep in stages. Mika first, curled against Taro, who was next, still watching the unchanging fire. Their companions dimmed with them — Taro's dog lay against his side, finally still, and Mika's had gone quiet beside it, the two of them touching at the edges like sleeping animals sharing warmth. Sora's fragments scattered loosely around her, drifting in slow orbits that widened as she slept, mapping the clearing on their own. Sora and Kai on opposite sides of the clearing, each awake longer than they let on. Kai's companion was the last thing Aiko noticed before she stopped looking — still upright, still watching, even after Kai's breathing had gone slow and even.

Aiko and Ren sat at the edge of the light. His bad leg was stretched out in front of him, the bandage dark where it had bled through. His companion hadn't come back to him — it was still out there, a faint dense shape at the treeline, facing away.

"You okay?" she asked.

He glanced down at his leg like he'd forgotten about it. "It doesn't hurt as much as it should." His companion didn't stir.

That wasn't an answer. She didn't push it. But she thought about Sora's voice in the dark — *mimics would track* — and the clean curve of the cut that didn't match anything on the ground.

She pulled her knees up. Her companion dozed in her lap, its warmth pulsing gently. "This place is going to change us," she said. Not a question.

"Probably."

"I mean really change us. Not like growing up changes you or moving cities changes you. Something deeper." She was quiet for a moment. She had the strangest feeling — not that they were being watched, exactly. More like they were being *read*. "I'm scared it'll change us in ways we can't see. Like, we'll be different and not even realize we're different."

Ren looked at her. In the amber non-light of the perpetual fire, his expression was hard to read, but his voice wasn't. "Then we watch each other."

"Yeah?"

"If I ever go too far — if I start becoming something I shouldn't — you stop me."

She held up her hand, pinky extended. An absurdly childish gesture for the weight of what they were sealing. "Only if you promise the same."

He hooked his pinky around hers. "Even if you hate me for it."

"*Especially* then."

They held it for a beat too long. In Aiko's lap, her companion shifted — a small, warm pulse, like a heartbeat that wasn't hers. At the treeline, Ren's companion turned its head. Just slightly. Just once.

Then Aiko laughed, softer this time, and the sound carried across the clearing. Taro smiled in his sleep.

---

The next morning, Taro told the fireworks story again.

They were walking through a section of forest where the trees grew in spirals, their bark shifting color as the light moved. Mika was beside him, close the way she'd been since they entered, and he was telling her about the festival — the one he always told, the one that lived in his chest like a compass pointing toward something he couldn't name but couldn't lose.

"—and the sound hits you first," he said, "this deep thud you feel in your ribs, and *then* the colors bloom, and for this impossible second the sky is just — holding its breath—"

Mika's hand tightened on his arm.

He didn't notice. He kept talking, his voice warm, his face lit up. The same story. The same Taro.

But Mika had heard him tell it in the waiting room. She'd been the one listening. And in the waiting room, the colors came first. He'd been specific about it — the colors hanging in the air, *then* the sound. He'd even corrected himself mid-sentence and laughed about always getting the order mixed up. She remembered because she'd thought it was sweet, the way he held the memory so carefully.

Now he was telling it with the sound first. Confidently. No correction. No laugh. As though this had always been the version.

She opened her mouth. Closed it. Opened it again.

"Taro — didn't you say it the other way yesterday? Colors first?"

He looked at her. Genuinely confused. "No? It's always the sound first. That's the whole point — you hear it before you see it. Like thunder."

"You said colors. In the waiting room. You said the colors hang in the air and then—"

"Mika." He laughed. The same warm laugh. "I think I know my own memory."

It wasn't that he was wrong. It was that he was certain.

She let go of his arm.

He kept walking. His companion padded beside him, fully formed now — a dog, clear and solid and real in a way it hadn't been yesterday. It wasn't cycling anymore. It wasn't searching. It had settled into a shape, and the shape was content, and Taro was scratching behind its ear like he'd been doing it his whole life.

For a half-second — so brief she almost missed it — Mika didn't recognize him. Not his face. His *rhythm*. The way he moved, the way his weight settled into each step. Something in the pattern had shifted, like a song transposed into a key that was technically the same notes but wasn't the same music. Then it passed, and he was Taro again. Or close enough.

She fell back a step. Then two.

She looked at the others. Sora was ahead, fragments mapping paths. Ren and Aiko were side by side, their companions in easy parallel. Kai was walking alone, his companion behind him.

Nobody else had heard the story in the waiting room. Nobody else would know.

She could say something. Pull Aiko aside. *He told the story differently yesterday.* And then what? The group splits over sound versus color. Day two. Over a fireworks story. She could already feel how small it would seem to everyone else.

She watched Taro's back as he walked. Same posture. Same stride. Same boy she'd curled against by the fire the night before. Except for one detail — one small, inverted detail — that she couldn't prove to anyone and couldn't stop hearing.

If she was right, something had already changed him. If she was wrong, something was changing her.

She said nothing. She kept walking. Because if she was right, he was already gone.
