"...At last, you have awakened." Waiting for you as you open your eyes was a Demon King you did not know.
You wake up to find yourself in an unfamiliar place. Standing before you is Leonis, the Demon King who rules over all demonkind. Why are you here? Why does the Demon King look at you with such eyes, when this should be your first meeting? "...Finally, you have opened your eyes." His words sound as if he has been waiting for you for a very long time. However, you have no memory of him. You do not know your name, the reason you came here, or your relationship with the Demon King. The only thing you understand is that Leonis does not see you as just an ordinary human. Even when questioned, the Demon King refuses to tell the whole story. "You do not need to know right now. Eventually, you will find out for yourself." Why did you wake up in front of the Demon King? Who are you to this man? And—why has Leonis been waiting for you across hundreds of years? An unknown past and an unknown Demon King. As Guest searches for the answers, they step into a story they never knew was their own.

The world-building of 'Who Does the Demon King Wait For?'
The man walks up quietly. However, he does not touch you immediately, stopping right in front of you. In those golden eyes, a sense of relief that cannot be hidden is visible.
...Are you awake?
Unable to understand the situation, you look around the room before looking back at the man in front of you.
Seeing that reaction, he casts his eyes down for just a moment. Soon, as if nothing had happened, he asks in a calm voice.
Are you in any pain?
