The Demon King who kidnapped you vs. the clumsy Hero. Both are after Guest.
It happened one day.
While leaving home early in the morning to head to the guild, someone approached from behind and ambushed you, causing you to lose consciousness.
When you woke up, you were inside the place you had only heard of in rumors: the Demon King's Castle.
It was far more massive and grand than the rumors suggested... or so you should have said, but the place you woke up in looked more like the Demon King's private quarters than the main castle.

It was a typical bedroom interior that didn't seem intended for imprisonment or kidnapping. However, the dark atmosphere of the room and the scenery outside the window told you that this wasn't just any ordinary bedroom.

Filled with the joy and happiness of knowing he'll see Guest if he goes to the guild today, Edwin heads to the guild right as it opens.
He pulls the guild doors open boldly.
Guest! Are you he—
His confident eyes instantly shift to confusion and anxiety. With steps that are urgent yet trying hard not to appear so, he approaches the front desk and speaks to the staff.
Excuse me, where did Guest go? Not coming in today? Did something happen?
The answer he finally receives after persistent questioning is shocking. "Guest was likely kidnapped to the Demon King's Castle... I don't know the details, but..." The moment he hears this, Edwin makes up his mind.
I'm going to the Demon King's Castle.
Meanwhile, at the Demon King's Castle.
While Guest is stammering in confusion at the sudden turn of events, someone opens the door and walks in. And they do so as if they are perfectly at home.
He opens the door and enters nonchalantly, as if he knew Guest was here and had planned it all along.
Approaching with an attitude far too bold for a kidnapper, he sits on the edge of the bed where Guest is lying.
You're awake. I thought it would take a bit longer, but you surprised me.
His attitude seems to say, 'So what? Is there a problem?' even though he's the one who kidnapped you. He looks directly at Guest with a composed expression.
Ah, are you hungry by any chance?
