The night felt heavier than usual.
Not silent.
Not peaceful.
But suffocating.
Like something unseen was watching from the shadows… waiting for the perfect moment to strike.

## A Fragile Calm
Shadow Academy had begun to recover physically.
Buildings were being repaired.
Training sessions had resumed.
Students tried to return to normal.
But deep down—
Everyone knew.
Nothing was normal anymore.
The war had changed everything.
And the biggest change of all—
Was Arata.
---
### The Isolation
Arata stood alone in the training field.
The sky above was clear.
But inside him—
A storm raged.
His fists were clenched.
His breathing uneven.
Every time he tried to focus—
He felt it.
That presence.
That shadow.
Watching him.
Waiting.
"…Show yourself."
Silence.
Then—
A faint whisper.
*You called me?*
Arata's eyes hardened.
"…I won't let you control me."
A low laugh echoed in his mind.
*You already lost control once.*
*And you will again.*
Arata gritted his teeth.
"No."
The golden mark on his hand flickered.
But for a brief moment—
It turned black.
---
### Training Gone Wrong
"Still talking to yourself?"
Ren's voice broke the tension.
He walked into the field, stretching his arms.
"…That's not a good sign, you know."
Arata exhaled slowly.
"I'm fine."
Ren raised an eyebrow.
"You look like you haven't slept in days."
Lyra followed behind him.
Her sharp eyes immediately scanned Arata.
"…Your energy is unstable."
Arata looked away.
"It's nothing."
Ren smirked.
"Yeah, because turning into a walking bomb is 'nothing.'"
Lyra stepped closer.
"Train with us."
Arata hesitated.
Then nodded.
"…Fine."
---
### The Test
They moved to the center of the field.
Ren cracked his knuckles.
"Let's see if the 'hero of the world' still has his touch."
Lyra raised her hand.
Golden threads formed instantly.
"Controlled sparring."
Arata stepped forward.
His aura flickered faintly.
"Let's go."
---
### The Fight Begins
Ren attacked first.
"Frost Strike!"
Ice energy shot forward.
Arata moved.
Effortless.
He dodged.
Countered.
"Resonance Pulse!"
The shockwave pushed Ren back.
Lyra followed.
"Light Bind!"
Golden chains wrapped around Arata.
But—
They shattered instantly.
Ren smirked.
"…He's still strong."
Arata stepped forward.
Faster.
Sharper.
Better.
But then—
Something changed.
---
### The Shift
His vision flickered.
The world distorted.
For a split second—
Everything turned dark.
The shadow whispered.
*Let me help you.*
Arata froze.
"…No."
Ren frowned.
"…What?"
Arata's body moved suddenly.
Faster than before.
Too fast.
He appeared behind Ren.
And punched.
**BOOM**
Ren was sent flying across the field.
Crashing into the ground.
Hard.
Lyra's eyes widened.
"…That wasn't controlled."
Arata stood still.
His breathing heavy.
"…I didn't mean to—"
The shadow laughed.
*Liar.*
---
### Losing Control
Arata's hand trembled.
Dark energy spread across his arm.
The golden mark flickered again.
Black.
Gold.
Black.
Gold.
Lyra stepped forward.
"Arata, stop."
But he didn't respond.
His eyes—
Had changed.
Partially.
One gold.
One dark.
Ren struggled to stand.
"…Okay… that's new."
Arata spoke.
But his voice—
Was different.
"…Move."
Lyra froze.
"…That's not him."
---
### The Danger
Arata stepped forward.
Slow.
Controlled.
But dangerous.
The shadow spoke through him.
*They are weak.*
*Let me show you real power.*
Lyra's aura flared.
"I won't let you hurt anyone."
Arata tilted his head.
"…Try."
He vanished.
Lyra barely reacted.
Their clash shook the field.
Golden light vs dark energy.
Ren shouted,
"ARATA! SNAP OUT OF IT!"
But Arata didn't listen.
Because he wasn't fully there anymore.
---
### The Breaking Point
The fight escalated.
Arata's attacks became sharper.
More brutal.
Less controlled.
Lyra was forced back.
Her defenses cracking.
Ren joined again.
Ice and light combined—
But it wasn't enough.
Arata overwhelmed them.
Slowly.
Relentlessly.
The shadow laughed.
*This is what you wanted.*
*Power.*
*Dominance.*
*Control.*
Arata's mind screamed.
*STOP—*
But his body didn't listen.
---
### Kaito's Arrival
Suddenly—
A massive pressure hit the field.
Everything stopped.
Kaito stood there.
Eyes glowing.
"…That's enough."
Arata turned toward him.
For a moment—
Silence.
Then—
He attacked.
---
### Teacher vs Student
The clash exploded.
Kaito blocked effortlessly.
"…You're letting it take over."
Arata didn't respond.
He attacked again.
Faster.
Stronger.
But Kaito—
Didn't move.
He countered.
Each strike precise.
Controlled.
"…You're not thinking anymore."
Arata roared.
Dark energy exploded.
The Third Gate power began leaking again.
Kaito's expression hardened.
"…So it's come to this."
---
### The Suppression
Blue energy surged.
"GRAVITY DOMAIN."
The world bent.
Arata's movement slowed.
His body forced down.
But he resisted.
The shadow screamed.
*BREAK IT.*
Arata pushed harder.
The ground cracked.
The domain trembled.
Kaito's eyes widened slightly.
"…He's resisting even this?"
---
### The Choice
Inside his mind—
Arata stood in darkness again.
The shadow stood before him.
Now fully visible.
A twisted version of himself.
"You're weak," it said.
"I'm stronger."
Arata clenched his fists.
"I don't need you."
The shadow smiled.
"You already used me."
Silence.
Then—
Arata stepped forward.
"…Then I'll control you."
The shadow laughed.
"Try."
---
### Back to Reality
Arata's body stopped struggling.
The dark energy stabilized.
For a moment—
Everything became still.
Then—
He collapsed.
---
### Aftermath
Silence filled the training field.
Ren lay on the ground.
"…That… was insane."
Lyra exhaled slowly.
"…He almost lost control completely."
Kaito looked down at Arata.
"…Not almost."
His voice was serious.
"…He did."
---
### The Warning
Later—
Inside the medical room.
Arata sat quietly.
Awake.
But silent.
Kaito stood in front of him.
"…Listen carefully."
Arata didn't look up.
"That thing inside you…"
"…is not just power."
He paused.
"It's a separate will."
Arata clenched his fist.
"…I know."
Kaito's voice became firm.
"If you lose control again…"
"…I will stop you."
Silence.
Arata nodded.
"…I understand."
---
### Final Scene – The Abyss King
Deep within the Abyss—
The throne room trembled.
The massive figure stood.
Fully now.
Visible.
Dark.
Overwhelming.
"…The successor is breaking."
A smile formed.
"Perfect."
Its voice echoed across the void.
"…Soon…"
"…he will destroy himself."
To be continued...
