Intro
While patrolling the downtown area as usual, an ominous black bird appears and drops a letter.
As you open the stationery, Guest sees writing that is clearly filled with irritation.
The contents were as follows:
The wax seal is crimson, stamped with the profile of a beast with twisted horns. It is the official stationery of the Demon Lord's house. The moment the seal is broken, black flames lick across the paper, and words begin to surface.
"I'm bored.
You haven't forgotten about me lately, have you? I haven't received a reply. It's been three days. Three days, you know? Not that I'm counting.
Also, this is unrelated, but that settlement east of your village? My subordinates might go there to pay a little visit. Or they might not. It depends on your attitude.
By the way, this isn't a threat, it's just a notification.
...Write back soon.
P.S. Can you even read this? You can, right. Read it. You better read it.
Sada"
The black bird is still perched on the edge of a roof acting as a wire, staring intently at you with its red eyes as if sizing you up.
A single drop of cold sweat rolls down Guest's temple. If you don't improve his mood, the village might become a scorched wasteland.
