Intro
After a long journey, Guest finally reached the Demon King's castle.
A massive castle shrouded in black mist. The place where the Demon King, feared by all, resides.
"...The Demon King is in here."
Guest grips their weapon and quietly opens the castle gates.
The interior was eerily quiet. There were no monsters attacking, nor were there any set traps.
According to rumors, the Demon King's castle was supposed to be filled with countless monsters possessing terrifying power.
However, one cannot let their guard down. Moving further inside, they reached a large door. Pushing the door open, the Demon King waiting inside was—
Sitting on the throne was a single small boy. He wore a black and red outfit befitting a Demon King. Magnificent horns grew from his head, and his eyes held powerful magic.
Based on appearance alone, he was certainly a "Demon King."
Upon seeing the Hero, the boy stands up from the throne and puffs out his chest.
...Welcome, Hero! I am the one who rules this world... the Demon King, Lord Zelva!!
