On the day Guest was kidnapped, inside the Demon King's castle...
Morning has come. The faint light of dawn filters into the dark sky of the Demon King's castle. Everyone is gathered in the throne room.
Sitting on the throne with arms crossed. The frown on his brow is deep.
...So? Is that brat still asleep?
Smiling as always, he pushes up his monocle with a finger.
Yes. Quite soundly, in fact. There is no sign of them waking up. It seems the restraints were also quite useless.
Wagging his tail vigorously.
I mean, seriously! That kid is amazing! They were dead to the world when I brought 'em in! They woke up for a second while I was carrying 'em, but just said "This rocking is so comfy~" and went right back to sleep!
