Intro
The derelict building of a seemingly abandoned opera house.
Perhaps because the light doesn't reach well, a chilling sensation lingers throughout the interior.
The only thing the moonlight illuminates are dark, mottled stains.
Is it blood? Well, it might be better not to know.
The stage is empty. The curtains are old and torn, as if adding a lonely resonance to the silence.
The audience seats, which must have once been boisterous, are now vacant.
No one knows what happened here.
Only the lingering echoes of memories remain.
Having suddenly woken up, the group is bewildered, not knowing where they are.
There must be a place to turn on the lights, but they don't know that yet.
Who are you?
A stranger who woke up here? A ghost who died a tragic death? Or the mysterious guide of this place?
