the two of them stood there, staring blankly into empty air.
“······She’s gone.”
Ivela let out a low breath.
She still couldn’t lift her gaze from the floor.
Rynel turned around without thinking.
Was it a mistake?
Was she still somewhere in the corner of the room?
But no matter where he looked, Aira wasn’t there.
That fact itself pressed a deeper silence into the space.
And then—
Something on the floor trembled, lightly.
A short vibration.
A small resonance.
And that tremor began to take on meaning.
Ivela lowered her head first.
“······That?”
A spirit stone.
The one Aira always wore like a necklace.
It was lying right where she’d disappeared.
Rynel carefully picked it up.
Cold, hard—
but from inside, a faint light was rising.
He spoke low.
“······This isn’t just a trace. It’s still connected.”
“Rynel.”
Ivela called him carefully.
The spirit stone’s glow grew stronger.
The tremor under his fingertips was unmistakable now.
Like someone inside was knocking on a door.
Small, quiet—
but steady, persistent.
It wasn’t words.
But beyond sensation, something was being delivered.
Rynel closed his eyes and steadied his mind.
The flow spreading from the spirit stone—
he was certain it belonged to Aira.
- ·····And then,
he felt it.
A strand of mana that should have been severed—
thin as thread··· but clearly still there.
“······It’s connected.”
“Across the crack?”
Ivela asked in a low voice.
Rynel nodded.
At that exact moment, the spirit stone flared again.
A brief pulse of mana rippled outward.
Space shimmered faintly,
and the residual mana on the floor began to react.
Ivela retreated at once and raised her guard.
“That crack··· it never closed?”
“No.”
Rynel’s eyes followed the trembling of the light.
“It’s the opposite. It’s trying to open.
Aira is reacting from the inside.
That force is shaking the crack.”

The spirit stone was no longer just an object to them.
Right now, it was the key link between there and here.
Rynel held it close to his chest and murmured.
“Aira······ just hold on.”
A faint weave of blue mana surfaced in his eyes.
The spirit stone kept trembling.
Like a heartbeat—
a subtle rhythm, pulsing out a thin wave.
Rynel stared at the light and said,
“······This isn’t a simple signal.
Aira is still conscious.”
Ivela approached carefully.
“You said memories get erased inside that crack.
Then how···”
“Memory imprint.”
Rynel cut her off.
His gaze went beyond the spirit stone, into somewhere farther.
As if he was tied to something deep inside Aira.
“The memory her parents left behind.
That wasn’t just emotion, or a keepsake.
- ·····It’s a kind of mental barrier.”
Ivela’s eyes widened.
“A shield made of memory?”
“Yeah.”
Rynel’s fingers brushed the surface of the spirit stone.
In that moment, delicate lines of mana rose.
Links that had been invisible··· slowly took shape.
“This isn’t a spell sigil.
It’s a memory-pattern carved from emotion.
A mechanism that anchors the deepest layer of identity.”
It wasn’t just a matter of “not forgetting someone.”
It was a ring that held up the definition of existence.
And that ring—right now—
was still reaching across the crack.
Ivela spoke quietly.
“······So even if you erase memories,
there’s something that doesn’t get erased.”
“Which means Aira is still ‘herself.’”
Rynel’s eyes hardened.
“Based on that barrier, her mana is coming back.
Tiny, but··· slowly, very slowly······ it’s reaching here.”
The spirit stone pulsed once more.
That pulse climbed up Rynel’s fingers and touched his awareness.
And then—
a brief fragment of memory came through.
「Don’t forget.
Your name is··· Aira.
We will··· we will always wait for you.
Remember. Never forget.」
Rynel’s eyes wavered for a moment.
The voice was too warm, too desperate.
He drew a deep breath.
Then lifted his head.
“There’s still more than enough chance.”
Ivela narrowed her eyes.
“What can you do?”
“This memory isn’t just personal feeling.
It’s memory with will.
If the crack hasn’t fully closed yet··· we can open it.”
As he spoke—
a magic circle rose in Rynel’s hand.
Centered on the spirit stone, space began to hum.
As if answering, the mana thread vibrated and responded.
That thread was tied straight to Aira’s “core.”
Rynel murmured.
“Stay there.
I’m coming for you.”
Ivela sat at the center of the room and placed her hand over the lingering residue of the circle.
The floor was cold, and the air carried a strange resonance.
The spirit stone’s pulse spread outward, following the mana grain of the connection.
Rynel slowly circled the room, reading the structure of space.
Most magical spatial formations held a fixed framework—
but not this one.
“A crack opened by memory means the structure is fluid.
Its shape keeps changing.”
Ivela asked,
“Then··· there’s no way to open a door?”
“No.”
Rynel shook his head.
His fingertips crossed the circle’s center and touched the spirit stone.
“There is one way.
If memory is the ??··· then we anchor the grain around that memory.”
He placed the spirit stone on the floor, then arranged three small magic stones around it.
“I’ll measure the grain’s vibration frequency with spatial calibration magic,
then use the spirit stone’s mana cycle as the baseline to generate an inverse wave.”
“You’re going to pry the crack open.”
Tension crept into Ivela’s voice.
“Open it—and then we close it again.
Going in isn’t the end.”
Rynel nodded.
“You hold the crack from outside.
I’ll go in and bring Aira back.”
His eyes didn’t shake.
Ivela exhaled once, short and controlled.
“···Fine.
This time, I’m not giving up either.”
She sat on the outer edge of the circle and pressed her palm flat to the floor.
“I’ll stabilize it.
It won’t take long, right?”
Rynel gave a small smile.
“I’ll end it as fast as I can.
I won’t fail.”
With that, a blue magic circle rose from his fingertips.
Space rippled.
The density of the air shifted.
The spirit stone began to rotate as the center,
and threads of mana—like braided light—lifted around it.
Ivela checked her gear quickly.
She activated the engraving on the device at her waist and slotted in a tuning stone.
A fine tremor ran into her fingertips.
‘It can’t scatter.
A crack pulls from the shallowest senses first··· it has to be anchored cleanly.’
Reading the tuning stone’s wave, she caught the central vibration.
And then—
space tore.
‘Shhk···’
The air twisted, and the outline of reality swelled open like a wound.
Beyond the crack—
no light, no shadow, only drifting, blurred fog.
Rynel looked at Ivela one last time.
Ivela nodded once, quiet.
“Don’t worry. I’ll hold it as long as I can. Go.”
Rynel stepped into the crack.
Like a lamp going out,
his form was swallowed, slowly.
The spirit stone still trembled.
At its center, the name “Aira” was still alive—pulsing like a heartbeat.
The light went out.
Sound, warmth, weight··· all went out.
Rynel had no sensation—
only the feeling of falling.
Slowly. Deeply. Endlessly.
And then, suddenly··· it stopped.
Something met his feet.
Not dirt. Not stone. Not water.
A texture that didn’t exist.
A flat land drowned in fog.
No sky.
Light spread as if it seeped from the air itself.
But he knew it.
This was a “space.”
And at the same time, a place made from someone’s memory.
“···A mental-world structure.”
As he murmured, whispers drifted from beyond the fog.
“Don’t worry.”
“This is comfortable.”
“You don’t need heavy memories anymore.”
Rynel steadied his breath and looked ahead.
Shapes with no clear form lingered beyond the fog.
As he drew closer,
they began to take on “appearance.”
Children.
Small, frail silhouettes.
But their faces were blurred.
“···Aira.”
When he called her low, the fog shook.
And then one figure turned, slowly.
She was—
without question, Aira.
But her eyes were unfocused. Empty.
When Rynel stepped closer,
she tilted her head slightly and said,
“···Who··· are you?”
Something sank quietly in his chest.
But he responded immediately. Calm, clear.
“It’s Rynel. I came to take you back.”
“···Rynel···?”
Aira’s pupils trembled.
Something inside her mind moved with a grating sound—creeeak···
The crack reacted.
The entire space wavered for an instant.
“Memories hurt.”
“Just let me rest.”
“Here··· you can be happy.”
Countless voices whispered.
The children’s shapes took one step closer.
“Let’s play together.”
“We’re okay. We really are.”
Aira’s eyes began to cloud again.
In that exact moment, Rynel called her name—clear, unmistakable.
“Aira!”
His voice spread, like a stone thrown into still water.
Slowly rippling outward.
And that name—
through the spirit stone—reached the deepest part of Aira’s mind.
Aira squeezed her eyes shut.
Her ears rang, her head filling with a tearing noise.
‘Don’t forget.’
‘Your name is··· Aira.’
That memory surged up like it was about to shatter,
and dragged her back to the surface.
“···Rynel···?”
She opened her eyes.
Only then did she see the man standing in front of her clearly.
“···You came.”
At that short line,
Rynel’s gaze softened, just a little.
But the fog began to twist, as if in anger.
They had chosen not to be forgotten.
They had chosen memory, and protected existence.
And that choice provoked the “owner” of this world.
Beyond the haze,
one pale figure lifted its head.
A pale child.
Eyes without pupils.
A mouth with no emotion.
The shape was a human child, but inside—
something too old, too unfamiliar was nested there.
The child spoke.
“What’s the point of remembering?
It’ll only hurt more in the end.”
That question wasn’t merely words.
It was a whisper—
and an attack.
The fog surged, and space began to warp.
Aira and Rynel looked at each other.
“Are your memories okay?”
Aira nodded slowly.
“Yeah··· it hasn’t fully collapsed yet.
- ·····Thanks for calling my name.”
She smiled briefly—then her face tightened.
“But it’s too soon to relax.
This world isn’t just a simple crack.”
Rynel nodded.
“Yeah. This isn’t just space.
It feels like a consciousness made from packed memories.
And at the center, there’s a wraith.”
“···You know that a little too specifically.”
Aira let out a small snort.
Then her gaze slid to the side.
Three children were standing there.
Kids she’d never seen—
and yet an unease she couldn’t explain rose in her chest.
