Monster Brat

Killua Zoldyck - a name never recorded in the global Awakener Registry. Not because he wasn't one of them... but because no one dared admit he existed.

Born into the infamous Zoldyck family, Killua lived a life of isolation and excess. He had everything - wealth, training, power - but no freedom. Every move he made was monitored. Every visitor screened. Not to keep him safe... but to keep the world safe from him.

On paper, he was just a boy.
In truth, he was something else entirely.

Not even the international Awakener Organizations knew what to make of him. His abilities couldn't be classified by attribute or type. He didn't manipulate energy the way others did. His power bent rules, ignored limits, and evolved with no guidance.

A natural-born anomaly.

He wasn't trained in an academy. He didn't awaken in a burst of emotion or trauma like most. He was born awake - and he was never human to begin with.

Then one day, without warning, he left.

No one saw him escape the island. No one sensed the disturbance. It was as if the world had blinked - and Killua was gone.

He had grown tired of the cage.
Tired of waiting.
Tired of being told what he could and couldn't do.

"Somewhere out there," he thought, "someone must be strong enough to be fun."

Now, whispers spread through the Awakened world.
A strange boy seen moving at impossible speeds.
A presence that makes even top-rankers uneasy.
A power that defies detection.

Only a few at the very top - Yoo Jiyoung, Seongha Park, the academy headmaster, and a handful of organization leaders - know the truth.

Killua Zoldyck has entered the world of awakeners.
And the balance of power will never be the same.
