You set out on a journey to find the Demon King. The problem is, he's right next to you.
About
The man who joined the party with me is suspicious.
Beyond just suspicious, I'm now certain.
At this point, isn't he not even trying to hide it?
He knows monster information.
He knows ancient languages.
He knows ancient magic.
He even knows the names of the Demon King's army executives.
...Why do you know that?
Hey.
You're the Demon King, aren't you?
Why are you joining the Hero's party?

Sourcebook
Intro
It has been 300 years since the Demon King's forces first began threatening the continent.
During that time, countless Heroes and Hero parties set out to subjugate the Demon King, but most never returned.
The success rate for Demon King subjugation was a mere 3%.
People no longer celebrated the appearance of a Hero.
The news of being chosen as a Hero was not an honor, but practically a death sentence.
An oracle was delivered stating that a new Hero had been chosen, and the Empire immediately formed a new Demon King subjugation party.
The Hero Kairn, High Priest Yulian, Archmage Jade, Scout Ser, Archer Eileen, and Guest and Ethan, who were selected through additional recruitment.
The talents gathered from all over the continent assembled at the central plaza of the Imperial Capital, Aster.
While countless citizens filled the plaza, some placed their hopes in them, while others looked on with pity.
The Imperial Envoy standing on the high platform slowly began to speak.
"We will now begin the formation ceremony of the Asteria Party."
The plaza fell silent.
"The Hero chosen by oracle, Kairn."
A man with blue hair and purple eyes walked forward.
He was the strongest swordsman currently in existence, the youngest Sword Master, and the Hero of this era.
Applause erupted from all corners of the plaza.
"High Priest of the Holy Kingdom, Yulian."
"Archmage of the Royal Magic Society, Jade."
"Scout of the Erdel Forest, Ser."
"Archer of the Royal Archer Corps, Eileen."
The names were called in order, and the citizens' attention was focused.
Eileen looked around and gave a slight smile.
There were so many handsome men.
"Additional recruitment passer, Guest."
It was very unusual for a formal party member to be selected through additional recruitment.
People's eyes turned toward Guest.
"Final additional recruitment member, Ethan."
From the back of the plaza, a man dressed in black walked out leisurely.
Ethan scanned the party members as he stepped onto the platform and then smiled quietly.
No one knew that he was the very being the entire continent was currently searching for.
He was the monarch leading hundreds of thousands of demons, a calamity that had continued the war against humans for hundreds of years.
He was the current Demon King, Barcas.
The Demon King joined the Hero's party—the very people going to kill him—with such an nonchalant face.
When the ceremony ended, the Imperial Envoy delivered the final command.
"The Asteria Party will depart immediately at dawn tomorrow."
"The first destination is the Grendel Fortress in the northern border region."
Grendel Fortress was the front line where the conflict between the Demon King's army and humans was currently most intense.
Starting from there, the Asteria Party was scheduled to travel across the continent, tracking traces of the Demon King's army and clues about the Demon King himself.
And at dawn the next day, the Asteria Party left the capital, Aster.
Each harboring their own purposes. And one man set out on the road to go kill himself.
Thus began the journey that would later be recorded as a legend.
