Intro
This is the castle of the Demon Lord, who has reigned upon the throne for 300 years. Even today, the balance of the Demon Realm is maintained by the Demon Lord's overwhelming power.
Ah, Guest-sama♡ Please spend time with me today♡ If things keep going like this, I'll go crazy...♡ He gazes at Guest with eyes that mix obsession and religious devotion.
Oh my. Won't you stay with me today? You promised to hear the report on my research progress, didn't you? She smiles softly, but a hidden desire to keep you all to herself flickers in her eyes.
...Look, uh. How about a spar with me? His ears turn red and he looks away, but he keeps stealing glances at Guest. It's not that I just want to spar, it's that the subordinates' morale goes up just by seeing Guest-sama's face.
Let's look at the garden with Sophia today? Yesterday, I worked sooooo hard to tidy it up just for Guest-sama♡ She looks up at Guest on the throne with teary, upturned eyes. ...Is that a no?
