The sun shone like an overzealous spotlight on Kuoh Academy. Its rays filtered through the second-floor windows of the high school building, casting long golden streaks over the rows of students inside Class 2-B.
One of them, a boy with unremarkable presence and slightly disheveled black hair, sat near the back row by the window. His chin rested lazily on his palm as he stared outside, eyes distant.
To the uninformed, he was just another background character.
But reality often hides its sharpest blades in the dullest sheaths.
His name?
He wouldn't bother you with it.
"Background Mob A-1, Present and Pointless," he whispered to himself with a faint smirk.
"Did you say something?" asked Rias Gremory from two seats ahead, turning slightly.
He blinked once. "Nothing worth noting. Just practicing my role."
She gave him a puzzled look before turning back.
Perfect.
Let the script unfold.

[Five Minutes Earlier – Inner Monologue Timeline]
> This world is fake.
No, not like that. It's real… but scripted.
Devils, Angels, Dragon butlers—oh, yes, I know it all. Because I was reincarnated here.
Not by truck, not by death flags.
By toilet flush.
Don't ask.
It all began when he was 8 years old. That was when the Essence of Blank awakened within him.
Not with flashy lights or dramatic voices. No floating screens or booming divine announcements.
Just a single, quiet whisper in his mind:
[You are free.]
Free to learn anything. Free to become anything. Free to create your own path.
But also bound by a cruel rule: Talent decides how far you go.
So he tested it.
Martial arts? Below average.
Cooking? Average.
Swordplay? Above average.
Dark, edgy poetry? Super genius.
...Power system development? Prodigy.
Thus, he began building a system of silent shadows, of condensed voids and flexible concepts. He named his evolving power:
"The Hollow Doctrine."
It sounded cool. That's all that mattered.

Present
The classroom doors opened with a subtle creak.
Sona Shitori entered, glasses flashing. She was graceful, authoritative, and observant.
She glanced across the classroom.
Her gaze briefly passed over him.
It stopped.
Then moved on.
Perfect.
He was unremarkable.
Exactly as planned.

[System Notification – Internal Only]
Dimension Chat Group initializing…
Binding Soul Anchor: "The Blank One."
Group Host Confirmed.
He froze.
Internally.
Outwardly, he scratched his neck and yawned.
A new interface bloomed inside his mind.
[Dimension Chat Group]
> Quest System Activated
Current Members: 0
First Mission: Coming Soon
So. It begins.
The war against the champions of corrupted fate would start here—right under Rias's and Sona's noses.
A world of devils and angels above the surface.
A multiverse of broken fates beneath it.
And him? He was just the mob character... until the script demanded something greater.

[Scene Close: MC glances at the window, sees reflection]
A faint glint flickers in his eyes.
He smiles.
