The blue mana trembled between Yuna's fingers.
Not dramatically.
It trembled the way things tremble that have been used too much and that the body can no longer maintain with the same stability as before. The light that had at first been clear, precise, almost clean, now had a blurrier quality, as though it were being sustained by concentration rather than reserve.
The remnant was ten metres away.
Aoi was behind Yuna, on the ground, with her hands on her chest.
The mark glowed beneath her clothing with a rhythm that did not belong to her.
It was not the rhythm of her breathing.
It was not the rhythm of her fear.
It was the rhythm of something using her from within.
Yuna understood it now.
She could not destroy the remnant piece by piece.
Every wound she made, every real damage she managed to open in that deformed body, forced the mark to take more from Aoi to close it. She was not fighting an enemy that regenerated on its own.
She was fighting an enemy that used a living person as a reserve.
The remnant took one step forward.
Yuna materialised a shield.
The strike came head on.
The shield absorbed what it could, but the impact travelled through her arms, her shoulders and her back with a vibration that almost made her lose her balance. The damp forest floor gave slightly beneath her feet.
"You can't win," said the remnant. "Every time you hurt me, she pays the price."
"I know," said Yuna.
The remnant stopped.
"You already know?"
"For a while now," said Yuna. "That's why I haven't killed you yet."
The remnant's pupil-less eyes stayed fixed on her.
It did not smile.
Its mouth no longer had enough humanity for a smile to be anything clear. But there was something in the way the corner moved, something too close to the satisfaction of someone who believes they have confirmed an advantage.
"You're running out of mana."
"Yes."
"Then it doesn't matter what you know."
Yuna did not respond.
She tightened her fingers.
The shield disappeared, and in its place three small plates of blue mana appeared, suspended at different heights. They were not large. They could not stop it completely.
But Yuna no longer needed to stop it.
She needed to direct it.
The remnant advanced again.
Yuna turned the first plate. The remnant's strike hit it diagonally and was deflected towards a tree. The bark exploded. The second plate appeared beneath the remnant's arm and forced it to lift higher than it wanted. The third closed in front of its chest like a minimal wall, not to block it, but to steal half a second.
Half a second was not much.
But for Yuna, in that moment, it was something.
"Almost over," said the remnant, looking past her towards Aoi. "Almost recovered everything you owe me."
Aoi looked up.
She was pale. Her lips were trembling. Her eyes were wet and her entire body seemed on the verge of breaking, but in her expression there was something that had not been there at the beginning.
Not acceptance.
Anger.
A small anger, fragile, newly born, but real.
Yuna saw it.
Good, she thought.
Hold on a little longer.
"I don't owe you anything," said Aoi.
The remnant looked at her.
For a moment, the forest seemed to grow darker.
"Your mother was supposed to live."
There had been a time when that man was not yet a remnant.
A time when his hands were not deformed, nor did his voice sound like something learned from death.
In that time, the house was small but warm.
There was a table with two cups of tea. A window looking out onto a quiet street. A pregnant woman sitting beside him, with a blanket over her legs and a tired smile, the kind that seem to carry more light than strength inside them.
The man was looking at her as though she were the centre of everything.
Not the world.
His world.
She took his hand and rested it on her belly.
"When it comes," she said, "I want it to know we were waiting for it."
The man tried to smile.
The smile came, but not completely.
Not because he hated the baby.
Not yet.
But because he loved that woman so much that everything else, even the future, seemed to exist around her.
Not alongside her.
Around her.
The memory ended with the woman's soft laugh.
And the present returned with a strike.
Yuna created a platform beneath her feet and jumped sideways just before the remnant crushed her against the ground. In the air she materialised four blue arrows. Two went towards the trees. One towards a rock. The last towards the mud in front of the remnant.
They were not attacks.
They were positions.
The remnant understood a second too late.
The points lit up and a short chain came from the ground, seeking its ankle. It broke it before it closed completely, but the gesture shifted the axis of its body.
Yuna landed, turned on one foot and formed a lance.
She threw it at the shoulder.
The tip went in.
The remnant stepped back.
Aoi screamed.
The mark glowed strongly.
The wound on the remnant began to close.
Yuna gritted her teeth and dissolved the lance before it penetrated further.
"It doesn't matter how you do it," said the remnant. "She always ends up paying."
"No," said Yuna. "That's what you want me to believe."
The remnant turned its head towards Aoi.
"I heard her die," it said. "And then I heard you cry."
Aoi went still.
Not because she understood the complete sentence, but because there was something in that voice that was not speaking only from the present. Every word seemed to come dragging another scene, another place, another moment in which she could not yet defend herself from anything.
The forest remained.
The darkness.
The blue mana.
The damp smell of the earth.
But the remnant's voice opened another door.
A door towards the day when everything began to break.
The hospital smelled of disinfectant.
The lights were too white.
The corridors, too clean.
The man waited outside a room with his hands clasped, unable to stay still. He stood up. He sat down. He stood up again. He watched a door that did not open and heard voices on the other side.
Quick orders.
Footsteps.
A brief alarm sound.
Then, silence.
The door opened.
A doctor came out.
He did not need to say much.
The baby was alive.
The mother was not.
The man did not cry at first.
That was the first emptiness.
He went still, as though those words had not yet found a place inside his head. As though the world had spoken in a language he could not translate.
Then he heard the crying.
The newborn was crying.
Aoi.
Someone tried to bring the baby to him.
The man looked at the baby.
Not with open hatred.
Not yet.
He looked at her with an incomprehension so deep it almost looked like calm.
From that room one life had come out.
And another had not.
The world had given him an answer that nobody had asked for.
One life for another.
The man did not say that aloud.
But something inside him began to.
In the forest, Aoi was trembling.
"No," she murmured. "I didn't..."
The mark pulsed.
The pain cut off the sentence.
Yuna raised a blue wall between Aoi and the remnant, not to block a strike, but to take those eyes off her. But the voice came through the wall all the same.
"From the very first day I understood what you were," said the remnant. "The price."
"No," said Yuna.
The remnant launched itself at her.
Yuna created two platforms in sequence. She stepped on the first, jumped towards the second and landed behind it. In the descent she formed thin chains, one around the wrist, another at the back of the knee, another at the neck.
She was not trying to wound it.
She was trying to slow it.
The chains did not last long.
The remnant broke them with a sharp turn, but that turn forced it to have its back to Aoi.
Yuna took advantage.
She drove blue needles into the ground around it.
The remnant looked at them.
"You missed."
"No."
"They didn't touch me."
"They didn't need to."
The needles glowed.
They did not form a cage.
Not yet.
They only marked out a space.
The remnant looked around.
"You keep thinking this is a fight."
Yuna breathed with difficulty.
"No. I'm waiting for you to let your guard down."
The remnant laughed.
The mark on Aoi lit up.
Aoi doubled over.
Yuna took a step towards her, but the remnant spoke again before she could reach her.
"Do you know what the worst part is?" it said. "I tried to raise her."
The sentence did not sound like a confession.
It sounded like a reproach.
As though even the years Aoi had lived under his roof were something he had lent her and was now coming to collect.
The forest opened again towards another time.
Years after the hospital, the man was still alive.
And Aoi too.
The man raised her.
Or at least, that was what people said from the outside.
There was food on the table.
There were clean clothes.
There was a house.
There was school.
There were schedules, paid bills, doors closed at night.
What there was not was a father's gaze.
Aoi grew up in a house where everything necessary existed, except the place for her.
The man filled the rooms with books.
First books about grief.
Then about death.
Then about souls.
Then came old texts, ancient religions, rituals, superstitions, accounts from people who claimed to have seen the dead, internet forums with responses written by desperate people, files downloaded from pages that no sensible person would have opened twice.
He did not know what remnants were.
He did not know the truth about hunters.
But he found pieces.
Shadows that retained will.
Dead who did not cross over.
Desires that survived the body.
Echoes.
Remains.
Something that stayed.
Nothing complete.
Nothing correct.
But enough for someone who already wanted to believe.
He did not find a way to bring her back.
He found a way to convince himself that Aoi was the door.
The same phrase appeared again and again in his notes.
Incomplete exchange.
Incomplete exchange.
Incomplete exchange.
His wife had not died.
She had been replaced.
And if Aoi carried a life that was not hers to have, then all it would take was returning it.
The present returned with Aoi's scream.
The mark had spread.
Grey branches climbed beneath the skin, from the chest towards the neck. Yuna ran towards her, but the remnant appeared between them, too fast, too heavy, too certain that Aoi's pain belonged to it.
Yuna formed a blue sword.
The remnant's arm struck the blade and pushed it back.
"You are not recovering her," said Yuna. "You are using her."
"She took it from me."
"She was born."
"She replaced her."
Yuna looked at it.
The fury rose in her chest, but it did not cloud her head. On the contrary. It made her see more clearly.
"You lost your wife," she said. "And you decided to lose your daughter too."
The remnant went still.
Only an instant.
But it was enough for something in its face to break.
Not physically.
Deeper.
Then the form closed again around the same obsession.
"Don't talk about my daughter."
"Then stop treating her like a grave."
The remnant roared.
The sound bent the nearest branches and for a moment extinguished the glow of the blue needles. Yuna felt the mana waver in her hands, but she did not release it.
Aoi tried to speak.
"I... I don't want..."
The pain took her voice.
Yuna turned slightly.
"Aoi."
The girl looked up as best she could.
She had tears in her eyes. The fear was still there, but it was no longer alone.
"I don't want to die..."
That sentence was not large.
It did not sound heroic.
It had no force.
But it was a choice.
Yuna took in air.
"Then stay with me."
The remnant extended its hand.
The mark responded.
It was not a strike from outside.
It was something worse.
The pain came from within.
Aoi screamed.
Yuna tried to cover her with a barrier, even knowing a barrier could not stop that. She did it anyway, because the body sometimes protects before accepting that there is no surface to protect against.
The remnant pulled at the mark with everything it had.
Aoi stopped screaming.
Her body fell to one side.
Unconscious.
The mark glowed with a horrible intensity.
The remnant straightened.
The wounds Yuna had opened disappeared. The arms lengthened. The back widened. The dark veins climbed the neck towards the jaw.
It believed it had won.
The man died years later.
It was not a grand death.
There was no complete ritual.
There was no final revelation.
Only a body consumed by years of obsession, a house too silent, open books, old papers, lit screens, notes about souls, returns and debts that nobody had called in.
In his final moments, he did not think of Aoi.
He thought of his wife.
She has to come back.
That was his last human thought.
And when he died, he did not cross over.
He could not.
He did not want to.
He woke as a remnant without knowing that had a name. Without understanding the rules. Without knowing that somewhere there were trained hunters who erased things like him.
But he remembered an idea.
She has to come back.
And in the world of remnants, an obsession can be form.
It can be direction.
It can be power.
Everything he had misread, everything he had understood through grief and madness, everything he had turned into a private truth, took the shape of a curse.
He found Aoi.
He did not see his daughter.
He saw the door.
So he left the mark.
Not to kill her quickly.
To take from her little by little.
To convince himself he was not murdering the only daughter he had left, but finishing an exchange the world had left incomplete.
In the forest, Aoi was not moving.
The remnant advanced towards her.
"Now she cannot refuse it," it said. "Now all that remains is to return her."
Yuna was on her knees.
One hand sunk into the earth.
The other still lit with a remainder of blue mana that barely responded.
She breathed.
Everything hurt.
Her arms.
Her back.
Her chest.
Her head.
But her head was still working.
And that was all she needed.
The regeneration was not free.
The remnant needed to activate the mark.
And the more it tried to complete the curse, the more it concentrated its power into a single point of itself. Not the visible body. Not the arms. Not the mouth. Into the core of the obsession that gave it form.
Yuna could not see it as a cord.
She could not touch it as a chain.
But she could do what she always did.
Give form to the field.
Give points to something that had none.
Give a purpose to the little she had left.
She stood.
The remnant looked at her.
"You're still getting up."
"I'm still here."
"You can't stop me."
"I don't need to stop you."
Yuna opened her hand.
The blue needles she had driven into the ground before began to glow.
The remnant looked down.
Now it understood.
Too late.
They were not failed attacks.
They were not the remains of a defence.
They were points.
Like the arrows in the flat.
Like the Celestial Constellation.
Like every thing Yuna had done since the fight began.
Preparation.
The needles connected with each other in nearly invisible lines. They did not form a cage. They did not seek to enclose the remnant's body.
They formed a frame.
A minimal, precise figure, around the place where the contaminated mana concentrated every time Aoi's mark responded.
Yuna was not creating a sword.
She was creating an edge.
The remnant launched itself at her.
Yuna did not dodge completely.
She could not.
If she moved too much, she lost the angle.
The strike grazed her side and sent her against a tree. The air left her lungs. For an instant she saw nothing but black spots.
But her hand stayed open.
The needles kept glowing.
The frame was still there.
The remnant turned towards Aoi.
"Stand aside," said Yuna.
The remnant looked at her.
"She took it from me."
"No."
Yuna stood again.
Her voice came out low, but clear.
"You lost your wife. And instead of grieving her, you turned your daughter into the place where you hid your pain."
The remnant opened its mouth.
"No—"
"Your pain did not give you the right to destroy her."
The mark on Aoi glowed again.
The remnant tried to take more.
That was the instant.
All its power concentrated on completing the curse.
Everything it was leaned towards Aoi.
Yuna closed her hand.
"Celestial Forging."
The blue mana tensed between the needles.
Not like a net.
Like a line.
A single one.
Thin.
Clean.
Perfect.
"Horizon Cut."
The cut did not illuminate the forest with an explosion.
There was no thunder.
There was no enormous wave.
Only a blue line that appeared between two things the remnant had tried to join for years: Aoi's life and her mother's death.
The horizon does not destroy the sky.
It does not destroy the earth.
It separates them.
The cut crossed the remnant's core.
The mark on Aoi's chest went out.
All at once.
Like a lamp with no current.
The remnant went still.
For the first time, the damage did not close.
The enormous form it had gained began to lose consistency. The shoulders dropped. The arms recovered proportions less monstrous. The dark veins went out one by one, but did not disappear entirely. The greyish skin tensed over a body that no longer had a source.
Yuna fell to her knees.
But it did not end there.
It could not.
If she gave it time, something might catch again. Something might remain. Something might try to drag Aoi back.
So she materialised a sword.
Not large.
Not spectacular.
A simple blade of blue mana.
The remnant saw her coming.
Its pupil-less eyes moved from Yuna to Aoi.
Aoi was still unconscious.
"Aoi..."
Yuna did not know whether that was regret.
She did not know whether it was possession.
She did not know whether it was only the echo of a man who, somewhere unreachable, had remembered too late that the girl he had used was also his daughter.
It did not matter.
Yuna drove the sword through its chest.
The remnant fractured.
The dark light keeping it together opened in fine cracks. First in the torso. Then in the neck. Then in the face, where the human form held out a second longer than the rest, as though even death needed time to release a face.
"Your pain," said Yuna, breathing with difficulty, "was not a reason."
The remnant came apart.
Not with peace.
Not with forgiveness.
With an ending.
The remains rose slightly in the dark air of the forest and then disappeared between the trees.
The silence returned.
This time it did not seem to be listening.
It was simply there.
Yuna let the sword dissolve.
Then she dragged herself towards Aoi as fast as her body allowed.
She fell beside her.
"Aoi."
No response.
Yuna searched for her pulse with trembling fingers.
One second.
Two.
There.
Weak.
But there.
She was breathing.
Yuna closed her eyes for an instant.
The mark beneath Aoi's clothing was no longer glowing. The grey branches were retreating slowly, like roots from which the earth had been taken away. One by one, the lines went out until they gathered at the central point.
Then that point too lost its light.
It did not disappear completely.
Where the curse had been, a pale shadow remained beneath the skin.
A scar.
Not a debt.
Aoi opened her eyes barely.
She did not seem completely awake. It was more as though she was returning from somewhere very far away.
She looked at Yuna.
Then she looked down at her chest.
The mark was no longer glowing.
Aoi took a few seconds to understand it.
When she did, her eyes filled with tears.
"It's gone..."
Yuna breathed with difficulty.
"Yes."
Aoi closed her eyes.
She did not faint.
This time she simply let the tiredness take a little ground.
"Thank you..." she whispered.
Yuna pressed a hand to the damp forest floor so she would not fall sideways.
Her whole body hurt. The mana barely responded. Every breath seemed to have to cross something broken before reaching her lungs.
But Aoi was breathing.
The mark was out.
And the remnant was no longer there.
"Thank me later," said Yuna. "For now just stay awake a little longer."
Aoi nodded barely.
The forest of Kagoshima fell silent.
Not the silence from before.
Not that silence that seemed to be listening from the darkness.
This was different.
Emptier.
More tired.
More real.
Yuna looked at the place where Aoi's father had disappeared.
Then at Aoi, alive in her arms.
The blue mana finally went out between her fingers.
And for the first time all night, Yuna allowed herself to close her eyes.
Just for a second.
