Pain did not arrive all at once. It settled into him with precision, concentrating first in his hands and head, sharper than it should have been, as though his body had lost the ability to dull it. The wind pressed against him with constant force as he climbed, not in violent bursts but in an unrelenting pressure that sought to peel him away from the surface beneath him. The root he clung to was immense, far too large to be considered a mere branch, its surface rough and uneven, formed of hardened ridges that cut into his fingers with every upward movement.
Each attempt to climb demanded more from him than the last. The bark tore at his skin until it split open, and the blood that followed only made his grip more unstable, coating his fingers in a thin layer that caused them to slip against the coarse surface. His arms trembled under the strain, not from exhaustion alone but from the constant resistance of the wind, which pressed against his body without pause.
Something warm began to run down from his head.
Without thinking, he lifted his right hand to touch it, his attention shifting for only a brief moment, but that moment was enough. The pressure of the wind found the weakness instantly. His footing failed, and before he could correct himself, his body slipped away from the root.
He fell.
The massive structure he had been climbing stretched around him as he descended, its countless roots extending in every direction, twisting and crossing through space like the veins of something far larger than he could comprehend. As he dropped past them, his gaze shifted upward, following the path he had lost, and that was when he noticed them.
Four figures.
They were above him.
They had already climbed higher than he had reached, moving along the same structure, not separated across distant branches but positioned along the same massive extension, their bodies aligned in a slow, steady ascent. Their movements were controlled, deliberate, focused entirely upward. None of them looked down. None reacted to his fall.
Far above them, the roots continued endlessly into a dense fog that remained distant, as though reaching it would require hours of uninterrupted ascent. It did not appear closer despite their progress.
Sora continued to fall.
Before he could process the distance or the figures above, the space around him began to twist. The structure of the roots shifted unnaturally, their positions bending as if they no longer followed any fixed arrangement. The distance between them stretched and folded at the same time, and the sense of direction lost meaning as everything around him distorted.
Then the heat came.
It did not rise gradually. The moment his body struck the surface beneath him, it burned. Solid metal met his back with a force that drove the air from his lungs, and the temperature of it was already extreme, searing through his clothing and into his flesh without delay. The air around him carried the same heat, thick and suffocating, making it difficult to breathe.
He was in a forge.
His body did not respond. It was not restrained, yet he could not move. He tried to scream, but nothing came out. There was no resistance stopping him, no force suppressing the sound. There was simply no mouth, no form through which the scream could exist.
Something stood above him.
It held a massive hammer, its shape formed from something that resembled both blood and crystal, its structure unstable yet solid, as though it had been forced into shape rather than created.
It came down.
The first strike landed against him with full force, sending pain through his body with absolute clarity. Before the sensation could fade, the second strike followed, then another, each impact connecting with the same precision, the same weight, the same certainty. The blows did not slow, did not change, and the pain did not lessen or distort. It remained sharp, defined, present with every strike as though his body was experiencing it for the first time each time it landed.
He tried to scream again.
Nothing came.
The strikes continued.
Time stretched into something that could not be measured. There was no rhythm to follow, no pause long enough to grasp, only the continuous descent of the hammer and the repeated impact against his body. At some point, something shifted. The absence that had prevented him from screaming no longer held, and the sound finally escaped him, raw and uncontrolled.
His body could move.
If he willed it, it responded.
But his mind did not grasp it. The realization failed to settle, buried beneath the repetition of pain and the overwhelming persistence of the strikes. He continued to endure them as though he remained unable to act, even when the ability had already returned.
Hours passed.
His voice broke under the strain of screaming, weakening until no sound followed his attempts. The effort remained, but the result no longer came. Still, the hammer continued to fall, each strike landing with the same force, the same clarity, as if nothing had changed.
Then everything stopped.
The heat vanished. The pressure disappeared. The presence above him was gone.
He lay on a cold surface.
Above him, the sky reflected him.
It was not a normal reflection. It did not depend on angle or distance. It aligned perfectly with him, exact in every detail, unchanged no matter how he shifted his gaze. It was not mimicking him. It was fixed.
He remained there for a long time, his body still, his thoughts slow to return. The pain had faded, but its memory lingered with unusual clarity, as though it had been preserved rather than experienced.
Eventually, he stood.
Everything around him shared the same nature. The ground beneath his feet, the space stretching outward, even the distant horizon all reflected him with the same perfect accuracy, forming a continuous mirrored world that extended without interruption.
Until he turned.
A line cut through the space behind him, clean and absolute, dividing the world into two distinct halves. On one side, the reflection remained, endless and precise. On the other, it ceased entirely.
Grass covered the ground beyond the line, soft and uneven, breaking the perfect continuity of the mirrored surface. Small flowers grew among it, their forms natural and unreflected, existing without duplication.
Someone stood there.
The figure had the same face. The same body. The same structure.
But it was not identical.
Blue hair.
Azure eyes.
Details that did not belong to him.
The figure looked directly at Sora, observing him with a calm expression before a faint smile formed.
"Hi," he said. "You look like you've been through a lot."
Sora did not speak at first.
He stood upon the mirrored surface, his gaze fixed on the figure beyond the dividing line, observing with the same quiet precision that defined all of his actions. The resemblance between them was exact in structure, yet it failed in the details, and those details were enough to separate them completely.
The eyes were the clearest divide.
Where Sora's remained hollow and without depth, the other's carried a steady weight, not exaggerated emotion, but presence—something stable that did not depend on being seen to exist.
The figure smiled, easy and unforced, as though the expression belonged to him rather than being chosen.
"Hi," he said. "You look worse than I expected."
Sora blinked once, slow and deliberate. "I am operational."
A faint breath escaped the other, something between a sigh and a quiet laugh. "You really think that answers anything?"
Sora did not respond.
The other stepped closer to the line, his movements natural, unguarded, stopping just before the boundary as though he had no need to test it. His posture remained relaxed, shoulders loose, his attention resting fully on Sora in a way that felt direct rather than analytical.
"You're not damaged in a normal way," he said, tilting his head slightly. "It's not like something broke. It's more like… something never finished forming."
"That assumption is incorrect," Sora replied immediately. "All required functions are present."
"Functions," the other repeated, the word carrying a trace of amusement. "You reduce everything to that." His expression softened slightly, though his gaze did not waver. "You can think, react, adapt. You can survive. But you don't live through any of it."
"Survival is sufficient."
"It's the minimum," the other said. "You stopped there and decided it was enough."
The statement did not carry force, yet it settled with precision.
Sora's eyes moved across the other's face, noting the subtle shifts in expression, the ease with which he held himself, the absence of that constant internal distance Sora himself carried.
"You are inefficient," Sora said.
The other smiled again, this time a little wider, not mocking, but undeniably amused. "And you're empty."
Sora did not react outwardly.
"Define empty."
The other exhaled quietly, then stepped closer until only the line separated them, raising his hand slightly as if to gesture, though he did not cross.
"It's not something you can define cleanly," he said. "It's something you notice when it's missing." His gaze lowered briefly to Sora's chest, then returned to his eyes. "You don't feel like you're there. Not fully. It's like you're always standing one step behind yourself, watching everything instead of being inside it."
"Observation ensures accuracy."
"Observation isn't the problem," the other replied. "It's that you never stop observing. You replaced yourself with it." His tone shifted slightly, becoming more grounded, more certain. "You don't exist unless something reflects you. That's how you've been holding yourself together."
Sora's gaze shifted for a brief moment to the mirrored surface beneath him, where his reflection remained exact, aligned perfectly with his form.
"That is how existence is confirmed," he said.
"No," the other answered, more quietly now. "That's how you learned to borrow it."
The word lingered.
Sora did not respond immediately. Something in his stillness changed, not visibly, but in weight, as though his attention had turned inward, examining the structure behind his own perception rather than the reflection in front of him.
"You claim I am incomplete," he said. "Yet you exist separately."
The other nodded once. "Because I didn't lose the parts you did."
"That implies you are unnecessary."
"It implies I'm what you're missing."
Sora's gaze moved again to the line. It remained absolute, clean, separating two states that could not overlap.
"You cannot cross," the other said, following his attention.
"Why."
The question came without pause.
"Because you won't hold," the other replied simply. "Not like this. If you try, you won't merge. You'll fracture."
Sora looked back at him. "Define fracture."
The other's expression shifted slightly, the ease fading just enough to reveal something more serious beneath it.
"You won't stay as you are," he said. "But you won't become me either. You'll end up as something unstable, something that can't keep a consistent form of itself." His eyes narrowed slightly. "You'll lose even the little you have."
That was the first statement that carried weight beyond analysis.
Sora stepped forward.
The mirrored surface remained unchanged, but the distance between them closed until he stood just before the line.
He raised his hand.
The movement was direct, without hesitation.
The other watched sora, his expression tightening just slightly, not in fear, but in focus.
"You don't understand what you're reaching for," he said.
"I understand the result," Sora replied.
"No," the other said quietly. "You understand the idea of it."
Sora's hand continued forward, stopping just before the line.
For a brief moment, neither of them moved.
The air itself seemed to tighten.
Then Sora's fingers touched the boundary.
The mirrored surface beneath him distorted, his reflection splitting apart into overlapping forms that failed to align. The line did not dissolve. It resisted, not as a force, but as a contradiction, as though his current state could not pass through without breaking.
A sharp pressure formed behind his eyes.
For the first time, his expression shifted—not into emotion, but into strain.
The other moved forward instantly, stopping just at the line, his voice sharper now.
"Stop."
Sora did not withdraw.
The pressure increased. His vision fractured, not into clarity, but into misalignment. His own form began to feel distant again, slipping away even as he stood still.
"You're not ready," the other said, more firmly. "You're missing too much. If you push this, you won't gain anything—you'll lose what little structure you have left."
Sora's hand trembled slightly.
That alone was new.
The distortion intensified, the mirrored world reacting to the instability, reflections breaking apart, failing to hold a single consistent image of him.
Then—
He pulled back.
The moment he did, everything settled.
The reflections realigned. The pressure vanished. The line returned to its clean, absolute state, as though nothing had happened.
Sora stood still, his hand lowered slowly.
The other exhaled, the tension leaving him in a controlled release.
"Yeah," he said quietly. "That's what I thought."
Silence followed, but it carried a different weight now.
Sora looked at him again, his gaze unchanged on the surface, but not identical beneath it.
"What is missing," he asked.
The other studied him for a moment, then answered, this time without hesitation.
"Not everything," he said. "That's why you're still standing." His eyes shifted slightly, focusing more precisely. "But enough. You don't feel properly. You don't connect what you perceive to what you are. And your existence…" he paused briefly, choosing the word more carefully, "is not stable on its own yet."
Sora processed that.
"And the eyes."
The other smiled faintly. "Yeah. That too."
Sora remained silent.
The other stepped back slightly, creating a small distance between them again, though the line remained untouched.
"We'll meet again," he said. "When you can cross without breaking."
