Chapter 0 - Firefly
“Emergency! Emergency!”
The Empire was in an uproar.
“The Firefly has infiltrated!”
“A national emergency!”
“All units, full combat readiness!”
It was a moonless night, engulfed by the darkness of the new moon.
The Empire trembled in fear at the sudden intruder. But the enemy wasn’t some vast, endless army. It wasn’t a horde of monsters the size of mountains, either.
It was just one person.
“Find the Firefly!”
“Stay sharp! Let your guard down and you're done for!”
His codename: Firefly.
They say the flap of a butterfly’s wings can stir a massive storm.
The Firefly was a symbol of terror. A top-priority target who would approach silently and set everything ablaze in destruction.
“Find the Firefly now! If we don’t, we’re the ones who’ll go down!”
“Damn it, how many countries has that bastard already brought to ruin? Gah—!”
In the darkness, Imperial soldiers fell one after another. There wasn’t even time to see who fell first.
“Aaargh!”
“Guhk!”
The uninvited guest in the shadows struck down the well-trained Imperial troops—and vanished without a trace.
“Aaaagh!”
Nothing remained. Only screams of chaos and a silence more deafening than sound.
And in the blink of an eye, even their heart was gone.
“This is bad! The Firefly stole the Core!”
“What?!”
“He took the Core—the Empire’s barrier is compromised!”
“We can’t activate the defense walls at this rate!”
“The enemy is advancing—gaaaargh!”
Bullets rained from the sky like shooting stars. Finally, as the monster horde broke through the walls, the Imperial general ground his teeth.
That cursed creature!
He was a butterfly that heralded destruction. A hellish butterfly—everywhere he passed turned to ruin.
No one knew his face, gender, or age. The Allied Forces had spent 20 years trying to catch him, and the entire continent had pleaded to find him.
But every attempt had failed—again and again!
The Firefly became the continent’s most dangerous threat… a living legend. Like some mythical butterfly no one had ever seen or caught.
And then, despite all his infamy and notoriety—he vanished. Just like that.
No one knew why.
He disappeared for a staggering 50 years. And yet, even after all that time, people still spoke his name.
“He must be dead by now, right?”
“He was the enemy, sure, but he was a genius. No one could touch his skill.”
“Who knows if we’ll ever see a legend like that again…”
But the Allied Forces never let their guard down.
“We must never be fooled. Firefly is hiding and waiting for the perfect chance.”
“Yes, the sly bastard is baiting humanity into lowering its guard.”
His disappearance had to be another scheme. That was how he always struck—from behind, without warning. And so, they scrambled.
“There must be a reason for his disappearance. Find out—fast!”
“Yes, sir!”
The continent racked its brains, trying to uncover the Firefly’s true intentions.
‘Firefly… what are you after…?’
‘What’s the meaning behind this silence…?’
And while they agonized over it for 50 long years—
“Damn it. This cursed wandering fate.”
A man appeared, wiping monster blood off his blade.
“Got lost again.”
The continent’s greatest—and unluckiest—man had returned.
