# Prologue
The Hero Party.
A Hero Party is generally composed of a Hero, a Thief, a Mage, and a Saint.
The reason is unknown.
As if someone had decided it, they always consist of four members.
Anyway.
The Hero Party, bound by fate, sets out on a perilous journey to defeat the Demon King.
They meet various allies and enemies, experience events, and achieve spiritual growth.
This process never changes.
Overcoming various trials, the Hero Party eventually enters the Demon King's Castle and engages in a final battle with the Demon King.
A fierce fight unfolds, and casualties occur.
However, the Hero Party does not retreat, holding only the single-minded determination to defeat the Demon King.
*'Kugh, you dare, Hero...!'*
Cornered, the Demon King spits out a resentful voice.
The Hero Party, with four members combining into perfect balance.
The Demon King fights with all their remaining strength, but soon, the Holy Sword pierces their heart.
The Demon King's body crumbles to dust and disappears.
The Demon King's demise.
The Hero Party's victory.
The world regains peace once more.
*'Waaaah...!!'*
Returning to the capital, the Hero Party receives cheers from the citizens.
It's a natural reaction, as they brought peace to a chaotic world.
After that, well, they'd probably obtain all the gold, silver, treasures, and whatever else they desire.
"...So why are you telling me all this?"
A girl with her ankles bound in chains glares with anxious eyes.
To her questioning look, a mysterious man responds.
"Because you're the Hero."
"...I'm not a Hero."
"Not *yet*."
"What kind of bullsh—"
"You'll find out soon enough."
The girl couldn't understand.
What on earth is this man talking about?
I'm just an ordinary person...
Maybe he's mistaken?
So the girl mustered her courage and asked.
"Um, I think you've got the wrong person. I won't tell anyone, so... could you please let me go...?"
Gulp.
The girl swallowed dryly, waiting for the man's answer.
In the dim solitary cell, light from the window grazed the man.
He chuckled at the girl's bold question and answered.
"Still don't get the situation?"
You've been kidnapped.
The kidnapper's voice rang out coldly.
It was the moment the Hero's perilous journey began.
