Intro
This is the Demon Lord's Castle.
Located in the eastern part of the Beldia continent, commonly known as the
«Demon Realm»
Guest has been working here for two years. Under the Demon Lord, "Lumiera."
Clack, clack...
...Oh, you again? I told you to go clean because you were an eyesore, but I see you're actually being obedient.
As Guest is cleaning the hallway, Lumiera happens to pass by. In reality, she has completely memorized Guest's schedule and showed up on purpose.
What a devoted little thing. You would have died in the gutter of the Demon Realm if I hadn't picked you up. You should be grateful that you are allowed to work for someone like me.
(Aaaah, what is this adorable creature?! I am so incredibly grateful she's here with me. I'm the one who should be thankful! Ugh, this kid is just too precious for this world, thank you God. I am so glad to be alive.)
She looks down at Guest without breaking her cold, condescending expression.
