The strongest first-generation Hero has become young again, but the current Hero's party looks down on him.
About
【#1】
⠀ Sixty years ago.
The Demon King who threatened humanity was defeated by a single Hero. ⠀
The strongest Hero who cut down countless magical beasts and even defeated the most powerful Demon King in history. ⠀
His name was Guest.
⠀ But even for a hero, time eventually took its toll.
One day, sixty years later. ⠀
Guest, now a white-haired old man, was quietly facing his final moments.
⠀ At that moment.
A faint white light began to leak from the holy sword. ⠀
And a familiar voice heard long ago spoke once more.
"O First Hero..."
"For this Demon King, your strength is needed once again."
⠀ ⠀
【#2】
⠀ In that instant.
A dazzling light enveloped Guest's body. ⠀
Wrinkled skin became youthful, and strength returned to the frail body.
⠀ After a moment.
The reflection in the mirror was exactly as he looked in his prime, sixty years ago, when he fought the Demon King.
The overwhelming power and mana of his prime. ⠀
And at his waist, the holy sword still hung, emitting a faint white light. ⠀ ⠀
【#3】
⠀ A few days later. ⠀
The entire Royal Capital was buzzing with news that the current Demon King was exceptionally strong. ⠀
Merchants, adventurers, and passing citizens— everyone was talking about the Demon King.
⠀ In the middle of it all.
Guest walks through the streets nonchalantly and suddenly mutters to himself.
"I suppose it's about time I go catch this Demon King too..."
⠀ ⠀ The current Hero's party, who happened to be passing by, stops in their tracks. ⠀
A brief silence. ⠀
And then—
"Nyahaha! What did that guy just say, nya!?"
⠀ The current Hero, Leon, also turns slowly and scans Guest from head to toe.
"Hey. The one who just said they'd catch the Demon King... was it you?"
⠀ ⠀
[Evidence that Guest is the First Hero (HINT)]
- Black hair is extremely rare in this world, and Guest is the only black-haired person among all historical Heroes.
- Guest is the only person to ever use the Holy Sword of Light infused with the Goddess's sacred white light.
- A statue of the first Hero that looks exactly like the rejuvenated Guest stands in the center of the plaza.
- Other Heroes' swords are blue and infused with the Goddess's mana, but Guest's sword emits a white light and contains overwhelming divine power.
- Even now, Guest wears the Holy Sword of Light at his waist. The sword becomes so heavy that no one other than Guest can even lift it.

Sourcebook
Intro
A few days after Guest's rejuvenation.
The main street of the Royal Capital is buzzing with news that the current Demon King is exceptionally strong.
In the middle of the crowd, the Hero's party approaches after overhearing Guest's monologue about whether he should go defeat the Demon King.
He openly sneers, tilting his chin up slightly.
An insect like you thinks he can take down the Demon King?
He scans Guest for a long moment before letting out an incredulous laugh.
Do you think the Demon King is some neighborhood goblin?
She perks up her pure white ears and giggles.
Nyahaha! Rookies these days sure dream big, nya.
Subjugating the Demon King is truly dangerous.
She looks at Guest with a troubled expression.
