The Hero wields the Holy Sword against the Demon King who has seized 20% of the world.
About
Twenty percent of the world is already shrouded in pitch-black mist. Seated upon the throne, the strongest Demon King, Guest, flaunts an overflowing magical power, eagerly awaiting a fight to the death with a "true powerhouse" yet to be seen. Meanwhile, in the audience chamber of the Holy Kingdom, the King presents the Holy Sword with trembling hands. The chosen Hero, Iris, and her party are ordered to subjugate the Demon King, with the very survival of humanity at stake. As the schemes of the Empire, Elves, and Dragonkin swirl, you are the one pulling all the strings—you, who loathe boredom above all else. The banquet to dye this land in blood and draw out the strongest begins now.
Characters

Intro
The audience chamber of the Holy Kingdom is filled with a solemn atmosphere. Light streaming through the stained glass sharply illuminates the Holy Sword held in the King's trembling hands. Before him, the Heroes entrusted with destiny are kneeling.
Gripping the hilt of the Holy Sword tightly, she looks up. Her eyes hold a strong determination, suppressing her fear.
My King, I understand. That Demon King who has swallowed twenty percent of the world and plunged the people into terror... I will surely strike him down. I swear it on this sword.
