The first thing Yukinae noticed about Runa X was the size of the trees. They weren't beautiful in the way stories tried to describe ancient forests, and they didn't feel magical in any soft or comforting sense. They were simply massive, as if the world had grown upward and forgotten to stop.
Their trunks rose through the mist like pillars holding the sky in place, bark thick enough that entire paths had been carved into it over time. Some of those paths had become roads. Others had become homes. Higher up, whole structures rested between branches, and suspended walkways curved through layers of wood, metal, and faint glowing support lines she didn't yet understand.
It didn't feel like nature anymore. It felt like nature had been negotiated with.
Yukinae followed the river into the settlement the way her father had once taught her. Always follow moving water, he said. It would either lead you somewhere people lived, or somewhere people used to.
Either way, you wouldn't stay lost forever.
But Runa X didn't feel like somewhere people simply lived. It felt like something that had learned how to continue existing with people inside it. The scale of it made her feel smaller with every step, not just physically, but in the way her presence seemed irrelevant against everything already in motion.
None of that mattered as much as Mira.
Mira's weight shifted unevenly against her shoulder, each step Yukinae took forcing her to adjust slightly so she wouldn't slip. Her sister had gone limp in a way that didn't resemble sleep. It was heavier than that. Final in a way Yukinae refused to name.
Mira had stopped responding properly since the night before. Her breathing came in shallow interruptions, as if her body had forgotten the pattern and was trying to remember it one breath at a time. There were moments where Yukinae had to focus just to convince herself she could still feel her at all.
Her own injuries pulsed in the background—bruises, strain, the aftermath of escape—but they were distant compared to the constant pressure of Mira's condition. Pain could be ignored. Loss could not.
She tightened her grip slightly and kept moving through the lower walkways.
The village did not slow down for them.
People passed in steady streams. Farm workers with soil-stained sleeves and tired eyes. Mechanics carrying tool cases that hummed faintly with stored energy. Courier riders stepping off hovering boards that hissed softly as they settled against the air currents. Children weaving through market stalls, carrying bundles far too large for their size, laughing as they moved between adults who didn't look up long enough to notice them.
A few people glanced at Yukinae and Mira. Most did not. The ones who did eventually looked away again, not out of cruelty, but out of practiced distance. The kind that forms when a place teaches its people how to keep moving.
The path eventually curved around one of the enormous roots that cut through the center of the settlement like a buried spine. Beyond it, the hospital grove came into view.
It had been grown directly into the side of a massive tree. Pale bark had been reinforced with metallic veins that pulsed faintly with light, and layered walkways spiraled upward around its trunk. Movement flowed through every level—people carrying medicine crates, folded blankets, sealed containers, glowing record slates that flickered with shifting data.
It didn't look built. It looked adapted. As if the tree had been convinced, over time, to become something else.
Yukinae pushed inside.
The air changed immediately. Cooler. Cleaner in a way that felt controlled rather than natural. The scent shifted into overlapping layers of herbs, damp wood, heated metal, and something sharp she couldn't identify. Movement continued in every direction, but it followed patterns—guided, structured, intentional.
Machines drifted between exposed roots overhead, suspended in place by faint fields of light. Crystal screens embedded in bark displayed shifting symbols and readouts. Somewhere deeper inside the grove, someone was crying, but no one stopped to acknowledge it. It simply existed alongside everything else.
A woman behind the intake desk looked up the moment Yukinae entered. Her expression sharpened instantly.
"What happened?" she asked.
Yukinae tried to answer properly, but her body faltered slightly as she shifted Mira's weight more securely.
"She collapsed yesterday," she said quickly. "Then again last night. She hasn't woken up since."
That changed the atmosphere immediately.
Attendants moved toward them without further prompting. Mira was lifted first, carefully transferred onto a platform woven from living roots reinforced with thin silver metal. The moment Yukinae let go, something inside her chest tightened sharply, as if her body had not agreed to the separation even if her mind had.
She was guided onto a nearby bed as well, though she barely registered it. One of the attendants passed a thin glowing frame over Mira's body. Symbols flickered across its surface too quickly to interpret, shifting in layered sequences that seemed to respond to something deeper than physical injury.
Another attendant asked Yukinae questions about her own condition, but quickly redirected once it became clear where her focus remained.
A healer studying Mira's readings frowned.
Then looked again, slower this time.
"What's wrong with her?" Yukinae asked.
No one answered immediately.
The silence felt heavier than any explanation would have.
More light passed over Mira's form. The platform beneath her pulsed faintly in response, as if reacting rather than measuring. One of the machines emitted a low, uneven tone that failed to stabilize into a rhythm.
Fragments of conversation drifted through the air.
"Instability…"
"…pathways aren't aligning correctly…"
"…why is it reacting like that?"
Eventually, the woman at the desk returned.
"We can stabilize her for now," she said carefully. "But she will require continued treatment cycles. Monitoring as well."
Yukinae's mind caught only one part of that clearly.
Not stabilize. Not treatment.
Continued.
"How much?" she asked.
The healer hesitated before turning a crystal display toward her.
Numbers filled the surface. Rows of them. Layered costs stacked into patterns that didn't need full comprehension to understand their weight.
Yukinae stared at it for a long moment.
Then she understood enough.
It was too much.
"We don't have that kind of money," she said quietly.
The healer's expression softened slightly—not dismissive, but familiar. As if she had given this answer before to people who had nowhere to put it.
"There are work contracts available through the guild district," she said. "Courier routes. Transport labor. Repair work if you have technical skills."
Yukinae's gaze drifted instinctively toward the open structure of the grove.
Above the lower walkways, she could see movement cutting through the air between branches. Hoverboards traced clean lines through the sky routes, fast enough that they blurred into streaks of light before vanishing deeper into the village.
Fast. Efficient. Always moving forward.
"I can work," she said immediately.
"You should rest first," the healer replied. "Both of you require recovery. Your injuries are not minor."
"I can work," Yukinae repeated.
Because resting did not keep Mira alive.
And Mira, still unmoving, still unresponsive, still held between machines and light, was not awake to argue otherwise.
Time passed in the grove without announcing itself. Machines continued their quiet rhythms. People came and went. Somewhere, a child laughed. Somewhere else, metal wheels rolled across a suspended walkway with steady precision.
Life did not pause for fear. It only adjusted around it.
Eventually, the attendants stepped back.
Yukinae was given a thin wooden marker etched with faint glowing numbers.
"This covers tonight," the healer said.
Yukinae closed her fingers around it.
Warm wood. Soft light. Temporary in a way that felt almost cruel.
Everything had been temporary lately.
She stood beside Mira for a moment longer, watching her sister's face under the shifting medical lights. Too still. Too small beneath the weight of everything surrounding her.
Then she turned away.
When she stepped back outside, evening had already begun settling over Runa X.
Windmills above the village turned slowly against the fading sky. Lanterns flickered alive along suspended bridges. Hoverboards crossed the upper air routes in flashes of blue and gold before disappearing into the deeper layers of the settlement.
Somewhere nearby, music drifted through the air. Somewhere else, machinery groaned loudly enough to vibrate through the walkway beneath her feet.
Life continued.
Yukinae stood still beneath the enormous trees.
The village felt unfamiliar now. Too large. Too alive. Too indifferent.
But something inside her had shifted.
Not hope.
Not comfort.
Something colder had begun to settle where panic used to be.
She looked down at the wooden marker in her hand.
Then toward the distant guild district barely visible through the layered branches and wind-lit structures beyond the windmills.
And finally—
She started walking.
She moved through the lower paths without stopping.
Past market lights.
Past moving crowds.
Past the sound of a city that never learned how to hold still.
Each step carried weight she didn't have the luxury of putting down.
Each breath felt measured.
Each thought narrowed.
Mira needed treatment.
She needed it too.
But only one of them was still awake to act.
And the city had already decided what survival cost.
Not in words.
In numbers.
In work.
In motion.
Yukinae tightened her grip on the marker.
She did not stop walking.
Not once.
Not even when the fear stopped feeling like fear.
Not even when it started turning into something else.
Something that didn't shake.
Something that didn't ask permission.
Something that simply moved forward.
Toward the guild district.
Toward whatever came next.
And behind her, Runa X kept breathing like nothing had changed at all.
