The pull came all at once.
No warning—
no shift in wind—
just a clean, downward force that snapped the world open beneath Aiden's feet.
Water rose around him like a throat swallowing light.
The sea didn't drag him violently; it drew him with purpose, like carrying something it had been waiting centuries to retrieve.
He sank.
Not through darkness—
through memory.
Light flickered along the walls of the fold, forming streams of images that bled into each other: a child crying behind a wooden door; a blade cutting sky; blood falling upward instead of down. None of them were his—
not exactly—
but they held the same cadence as his heartbeat.
The deeper he went, the quieter everything became.
Even the distant echoes of the Straw Hats—
Luffy's shouts, Nami's code pulses—
cut out one by one, like lanterns smothered by tide.
By the time he reached the first shelf of the deep fold,
Aiden was alone.
Completely.
The water cleared.
A floor emerged beneath him—
not sand,
not stone,
but a skin of woven light.
It pulsed in a rhythm that felt like veins.
The Ledger Sea.
A whisper bled through the stillness.
"Kyriel."
Aiden turned—
and saw it.
A creature waited at the edge of the light.
Shaped like a wolf carved from broken mirrors,
its ribs flickering with stolen memories.
Every breath it drew exhaled fragments:
a laugh,
a scream,
a door slamming,
a sword humming.
A Mnemo-Beast.
Aiden froze.
The Key burned against his palm.
Then the beast moved—
not attacking—
observing.
Studying the memories clinging to him like scent.
Its eyes—two spirals of folded time—
reflected not his face,
but the faces of the Kyriels before him.
The beast bowed its head.
Not in reverence.
In recognition.
Another voice rose behind him.
"You carry the Ledger's weight poorly."
Aiden spun around.
A figure stood there—
not a shadow this time,
not a flicker—
a complete form.
Tall.
Barefoot.
Wearing a coat that looked stitched from tidewater and starlight.
Hair tied back with a strand of silver thread.
Eyes clear and sharp—
not cold,
but heavy with a depth that could drown centuries.
The first Kyriel.
Aiden's throat tightened.
"You… you're real?"
The figure tilted his head, a faint echo of Aiden's own movements.
"Only where memory takes shape."
A pause.
"You descend into the Ledger Sea. You should have expected to meet what was written before you."
The Mnemo-Beast circled them, silent, its mirrored body catching pieces of past and present.
Aiden stepped back.
"Why did you call me here? Why cut me off from my crew?"
The first Kyriel's eyes lifted toward the folds above—
toward where the Straw Hats' voices had vanished.
"The moment you touched the Vortex, your paths diverged. The sea cannot echo two truths at once."
His gaze returned to Aiden.
"So choose the one you will walk."
Aiden's breath shook.
"You want me to abandon them."
"No," the first Kyriel said.
"I want you to stop mistaking echoes for answers."
The beast growled softly—
not at Aiden—
but at something deeper in him.
Fear.
Doubt.
Familiar fractures.
The first Kyriel stepped closer, and with each step, the fold brightened.
"Every Kyriel descends to the Ledger," he said.
"Only one rises."
Aiden stiffened.
"What does that mean?"
"It means," said the first Kyriel, "that legacy chooses. And Ledger keeps count."
The Mnemo-Beast suddenly lunged—
not toward him—
but toward a floating memory behind him.
A small glowing fragment—
Aiden's.
A laugh.
A voice.
A moment he didn't even realize he had lost in Chapter 15.
The beast swallowed it.
Aiden flinched.
"Stop! That—!"
"That is the Ledger's law," the first Kyriel interrupted.
"It takes what is not anchored.
It devours what is uncertain."
The water trembled.
Aiden felt something slip inside him—
a memory fragment trying to pull free.
He grabbed his head, teeth gritted.
"How do I stop it?!"
The first Kyriel's expression did not change.
"You don't stop it."
He reached out, touching Aiden's forehead with two fingers.
"You outgrow it."
Energy surged.
The folds roared.
The beast reared back.
Aiden saw—just for a heartbeat—
the memory of a Kyriel tearing open a sky with a gesture.
Then—
Everything snapped.
Aiden fell to his knees.
Lights flickered.
Beasts circled.
The first Kyriel's shadow stretched long across the sea-floor.
"You have descended," he said.
"Now ascend—
or drown."
The Ledger Sea pulsed—
once,
twice,
thrumming like a heartbeat counting down.
Aiden lifted his head.
He wasn't alone in the deep—
but he had never been in greater danger.
The first Kyriel extended a hand.
"Rise, Kyriel.
The sea is waiting for your answer."
And the Mnemo-Beasts closed in.
