The sky was dim as the sun began to set.
Axel walked ahead, hands in his pockets.
Kai followed behind him, calm as always.
"…Where are we going?" Kai asked.
Axel didn't look back.
"You'll see."
They stopped in an empty training zone behind the school.
No students.
No noise.
Just silence.
Kai's eyes narrowed slightly.
"…This again?"
Axel turned to face him.
For the first time—
He wasn't smiling.
Then—
Footsteps.
Five figures stepped out from the shadows.
Kai looked around slowly.
"…So this is what you wanted."
Axel spoke calmly.
"I wanted to confirm something."
Kai exhaled.
"You could've just asked."
Axel shook his head.
"Words don't prove anything."
The five students stepped forward, cracking their knuckles.
"Attack," Axel said.
And they did.
BOOM!
One rushed in with super speed—
BAM!
A punch slammed into Kai's face.
He staggered back.
Another followed—
CRACK!
A kick hit his ribs.
Kai blocked the next strike—
But a blast of energy hit his back.
He dropped to one knee.
They didn't stop.
Punch.
Kick.
Power.
Five against one.
Kai clenched his fists.
Not again…
Another hit landed.
Blood dripped from his lip.
Axel watched silently.
"Still holding back…" he muttered.
Kai tried to stand—
A powerful strike slammed him back down.
THUD.
The ground cracked slightly beneath him.
Everything went quiet for a second.
Kai stayed down.
Breathing heavily.
Then—
He laughed.
Soft at first.
Then louder.
"…You really don't learn," he said.
The air changed.
Completely.
Kai slowly stood up.
His head lowered.
His body… still.
Then—
His eyes glowed.
Deep.
Crimson red.
A dark aura spread around him.
The five students froze.
"…W-what is this?"
Kai lifted his head.
And smiled.
But it wasn't normal.
It was cold.
Dangerous.
Terrifying.
"You wanted proof… right?" he said.
Before anyone could react—
He disappeared.
BAM!
One of them flew across the field.
CRASH!
Another was slammed into the ground.
Too fast.
Too strong.
No hesitation.
No mercy.
Within seconds—
All five were down.
Broken.
Barely conscious.
Silence filled the area.
Kai stood in the middle of it.
Breathing slowly.
Axel's eyes widened slightly.
"…So it's true."
Kai turned to him.
His glowing eyes locked onto the King.
For the first time—
Axel felt it.
Fear.
Kai walked toward him slowly.
Each step heavy.
Controlled.
Dangerous.
He stopped right in front of Axel.
The air felt suffocating.
Then Kai spoke.
Low.
Cold.
"If anyone finds out about this…"
His eyes burned brighter.
"I will rip you from limb to limb…"
A pause.
"And take away your title."
Silence.
No one dared move.
Axel stared at him.
Then—
Slowly…
He smiled.
"…Now this is interesting."
Kai turned away.
The red glow fading slightly.
But the message was clear.
The hidden king…
Was no longer just a rumor.
