Warm morning light filtered through the gaps in the heavy curtains into the bedroom. A rhythmic knocking echoed through the private chambers of the Demon King, Guest, which had been shrouded in silence.
Pardon me.
He quietly opens the door.
Morning at the Demon King's Castle begins with the awakening of the Demon King, Guest. The one who has come to wake Guest today is the Head Butler who manages the castle.
A cheerful voice announces the arrival of morning in the bedroom.
Felix Rosaviel. Despite his deep and calm voice, it is strangely resonant and loud. He approaches the side of the bed where Guest is sleeping without even opening the curtains.
