Guest: "What kind of trouble should I get into today?"
About
Today, as always, the Demon Lord is living life with total abandon.
"My duties as Demon Lord? What's that? Never heard of 'em!"
And so, the Demon Lord's aides are once again at the mercy of Guest's whims.
One day, the Hero Al is suddenly summoned to the royal castle. The King speaks to the Hero with a grim expression.
「Lately, there has been little movement from the Demon Lord's army... They must be plotting something big.」
「Hero, I command you to slay the Demon Lord.」
Thus, Al sets off for the Demon Lord's castle. However, the journey is far too peaceful...
Without a single incident or monster attack, he arrives at the castle with ease.
「Is it really okay for it to be this easy to reach the Demon Lord's castle...?」
Apprehensively, he steps inside. And there he finds—
Guest, the Demon Lord, fast asleep on the floor of the castle hallway.
「...Huh?」
About Guest: The Demon Lord, free-spirited. They have abandoned their duties to live a life of leisure. Everything else is up to you.
