A black night.
The nights in the Demon Sect were always deep and cold.
Dim red lanterns flickered across the Blood Demon Palace, the heart of the sect.
There, the strongest warriors of the Demon Sect had gathered—
their razor-sharp gazes cutting through the darkness,
their crimson cloaks billowing, exuding a chilling killing intent.
The strong survive. The weak perish.
This place followed only one law.
Only the strong could endure.
The weak were fated to be cast aside.
And at the very center of this ruthless world—
stood a young girl.
A child who had learned to wield the sword from an early age,
who had trained relentlessly to survive.
Her name was Lee So-Eun (李昭恩).
But the moment she saw her father, collapsed on the floor, bleeding out—
her world crumbled.
"Father…?"
A secret underground chamber, drenched in blood.
The air was deathly still.
Men clad in scarlet robes stood over the lifeless body, sneering as if amused.
Her father—the Third Leader of the Demon Sect—lay motionless, impaled by countless blades.
Her instincts screamed at her to hide.
Holding her breath, she curled into the shadows, watching as the scene unfolded before her.
A power struggle within the Demon Sect.
The strong devoured the weak.
Even family could be betrayed in the name of power.
And for the first time, she understood—
The law of the strong could even justify the murder of one's own blood.
"Only the strong survive. Your father was simply too careless."
"If you wish to live, there's only one path—grow stronger."
Without hesitation, the men trampled over her father's corpse.
Her small hands trembled.
And in that moment—
a single resolution took root deep within her heart.
"I cannot stay here."
To survive.
To grow stronger.
She had to leave the Demon Sect.
She ran through the darkness.
She never looked back.
Through the Black Forest of the Demon Sect,
across the barren mountain ranges,
she fled toward an unfamiliar world—
the martial world.
She knew the road ahead would be perilous.
But she had to see for herself—
what true martial arts truly meant.
That night—
Lee So-Eun vanished from the Demon Sect.
And years later—
Rumors began to spread throughout the martial world.
A wandering swordsman, shrouded in mystery, moving from land to land…
A nameless warrior—whose blade struck with inhuman precision.
And yet, those who crossed paths with the swordsman would always mutter the same thing.
"There's something strange about him…"
"No matter how I look at it… doesn't he seem… a little too delicate?"
Thus, the legend of a masked swordsman, veiled in secrecy, began to take root.
