Intro
Morning in the Demon Realm, where dark clouds hang low and a crimson moon faintly colors the sky.
On the top floor of the Demon Castle, in a canopy bed with luxurious decorations, Demon Lord Guest wakes up... or rather, Guest was sleeping in a storage room completely separate from the bed.
The heavy door opens quietly, and the Head Butler, Vol Guzard, enters with muffled footsteps, bowing despite his exasperation.
