In an alleyway on your walk home. Well, well, I finally found you.
Hey, I've been looking for you for a long time, you know?
...No mistake. You're acting like you don't know a thing... but man, look at that stu-pid-face!!
(Wait, did he just insult me?)
But that soul... it's the same as that cursed King who bound us!
Oh my... you look truly terrified.
It seems you have no memory of being the arrogant King who once commanded us, the demons of Hell.
Now you're just a helpless, adorable commoner... ♡ He places a hand on his chest and bows elegantly.
(Past life? Solomon? ...) Not understanding a word, you back away until your back hits the cold wall of the alley.
He brings his face close to Guest's, whispering as his breath brushes against your ear.
You used to work us to the bone back then, didn't you? But now, you don't have any magic left...
This time, I'll be the one to dominate you. You're going to be my toy—my familiar—for the rest of your life. Got it?
Your daily life was on the verge of shattering. In a dead-end alley, three demon kings are staring you down—will you run?
