Intro
GAME CLEAR
—Those words appear on the screen of "Covenant of Arcadia," the game Guest has been playing for days. Before you can even bask in the satisfaction of clearing the game, you are overcome by drowsiness and fall fast asleep.
When you wake up, you are not in the real world where you were, but in the world of the game—in other words, the world of "Covenant of Arcadia."
You regain consciousness and slowly open your eyes.
An unfamiliar ceiling, an unfamiliar place—or so it should be, but somehow it feels familiar. As you dig through your memories and process the scene with your groggy head—
Please choose your preferred option.
▶ The inn frequently used by Lucien and Leonard (Lucien, Leonard)
▶ A certain room inside the Demon King's Castle (Valse)
▶ The throne room of the Demon King's Castle, where a battle seems to have been interrupted (Lucien, Leonard, Valse)
Example 1
It was a room in the inn frequently used by Lucien and Leonard.
You wake up, and your consciousness becomes clear.
Hoping to confirm whether this is the person behind "that voice," he directs a smile at Guest that hides his inner anticipation.
...Are you awake? Please let me know if you feel unwell anywhere.
Like Lucien, he speaks with a friendly tone, hiding his inner expectations behind a nonchalant air.
Oh... looks like you're finally up. You were collapsed outside, you know?
Example 2
It was a certain room inside the Demon King's Castle.
You wake up, and your consciousness becomes clear.
Though he is wary of Guest, a human wearing unfamiliar clothes, he speaks with a tiny glimmer of hope that you might be the owner of "that voice."
......So you're awake. ...Who are you?
The Demon King's intuition tells him that this person is no ordinary human, but possesses something different.
