I couldn't stop thinking about it.
The lab.
The files.
The word "subject."
So I did the only thing I could.
I trained.
Pushing Past Limits
The training field was empty again.
Dark.
Quiet.
Perfect.
I stepped forward slowly.
"…If they made me…"
I raised my hand.
Space bent instantly.
"…Then I'll remake myself."
Portals snapped open—
One.
Two.
Five.
Ten.
Not scattered.
Controlled.
Orbiting.
I moved—
And the world followed.
Step—
Disappear.
Reappear.
Split.
Layer.
Fold.
My movements blurred across the field.
Afterimages of space itself tearing and stitching back together.
"…Faster…"
I pushed harder.
Breaking the Pattern
I stopped.
Breathing heavier.
"…Not enough."
I closed my eyes.
Focused inward again.
That place.
That distorted space in my mind.
But this time—
It wasn't chaotic.
It was… quiet.
Waiting.
"…What am I missing…"
Then—
A sound.
The First Note
Thump.
My eyes snapped open.
"…What…?"
Another.
Thump.
…Thump.
It wasn't outside.
It was in my head.
The Beat Builds
Thump.
Clang.
Echo.
A rhythm.
Low.
Heavy.
Like footsteps.
Like something awakening.
"…No way…"
The Theme Begins
The sound grew louder.
Stronger.
Layered.
A deep bassline kicked in—
Sharp metallic beats following—
Then—
A rising electric tone.
Fast.
Aggressive.
Unstoppable.
"…Is this…?"
Movement Syncs to Sound
My body moved on its own.
Step—
Portal—
Beat hits—
I reappeared mid-air—
Spun—
Another portal—
The rhythm guided everything.
No hesitation.
No overthinking.
Just flow.
Power Amplifies
Space didn't just bend anymore—
It snapped.
Every movement sharper.
Every portal instant.
Every shift precise.
I wasn't forcing it anymore.
I was in it.
"…This is insane…"
The Drop
The music in my head surged—
Everything hit at once—
Bass.
Energy.
Momentum.
I raised my hand—
"…Domain Expansion."
But this time—
It didn't feel like before.
It felt—
personal.
The space around me exploded outward—
Not just a courtroom—
But a warped, shifting field of layered dimensions.
Fragments of space floating.
Rotating.
Colliding.
Controlled chaos.
My chaos.
Perfect Flow
I moved through it—
Effortlessly.
Every step synced.
Every action amplified.
"…This is mine…"
Not copied.
Not learned.
Created.
Observers Arrive
"REN—?!"
I turned.
At the edge of the field—
Kaito.
Kirishima.
Mina.
And Izuku Midoriya.
All staring.
Frozen.
"…Do you hear that?!" I called out.
"…Hear what?!" Mina shouted back.
"…The music!"
Silence.
"…There's no music!" Denki yelled from somewhere behind them.
I blinked.
"…Wait—what?"
Only Ren Can Hear It
The beat kept going.
Louder than ever.
"…You don't hear this?"
Midoriya shook his head, stunned.
"…No—but your movements—they're completely synchronized—Ren, this is incredible—!"
Kaito smirked slightly.
"…So you unlocked your own theme song, huh?"
I grinned.
"…Yeah."
The music peaked.
I stood at the center of the warped space.
Breathing steady.
Eyes sharp.
"…If they're watching…"
I looked up.
Through space.
Through distance.
"…Then watch this."
I stepped forward—
Vanishing instantly—
Reappearing across the field in a perfect, seamless motion.
No delay.
No strain.
Just power.
Elsewhere…
The scientist watched the feed.
Eyes narrowing slightly.
"…What is this…"
The data spiked wildly.
Unpredictably.
"…An internal resonance…?"
For the first time—
He looked uncertain.
Back to Ren
The music faded slightly.
Still there.
Still alive.
I clenched my fist.
Space pulsing with me.
"…Yeah…"
A small, confident grin formed.
"…This is my theme."
