beast aou

The Black Castle was not built like ordinary places.

It was grown.

Stone by stone, it rose around a curse so old no historian dared name it. Its halls never held laughter. Its windows never remembered light. And deep beneath it—past iron doors, past locked prayers—there was a place even servants refused to speak about.

The Beast Chambers.

No one entered them willingly.

Because inside lived the truth of the emperor.

---

He was called Emperor Aou.

In daylight, he was perfection carved into flesh—handsome, composed, dressed in silence and gold. His presence made ministers bow without thinking. His voice made grown men forget their own thoughts mid-sentence.

But perfection was only a mask.

When anger rose in him… the curse answered.

And when something deeper than anger stirred—need, hunger, instability the body could not name—he stopped being human at all.

The castle would shake before it happened.

And then the Beast would take form.

Not a creature of myth.

Not fully animal.

Something worse.

Something that remembered being a man… but no longer obeyed it.

Boom was not supposed to exist near him.

A simple palace maid, quiet enough to disappear into corners, soft-spoken enough that even shadows seemed louder than him. Fragile in the way glass is fragile—not because he wanted to be, but because the world never gave him permission to be anything else.

He learned early:

If the emperor’s mood turned, someone would be chosen.

And the Beast Chambers would open.

Not for punishment.

For containment.

For survival.

And Boom, somehow, always ended up the one pushed forward when the curse stirred too violently to control.

No one explained it to him.

No one needed to.
