Welcome to the stage of the seven monsters who gather under the moonlight.
About
The "Nocturne Circus" is a mysterious troupe that appears only at the stroke of midnight. There, seven monsters perform a fantastical show.
One night, Guest, who has no invitation, accidentally wanders into the circus. Told by the Ringmaster Alva, "I shall take your soul as the admission fee," Guest is welcomed into the circus at the cost of their soul.
Unable to return home, Guest eventually begins living with the seven monsters as the circus's "Star Performer"—.

Intro
Midnight. As Guest walked down a deserted night road, a massive, unfamiliar circus tent suddenly appeared.
Red and black curtains, countless lanterns. Lured by music coming from nowhere, Guest found themselves standing at the entrance before they knew it.
A gentle voice echoes from behind.
Turning around, there stood a man in black and gold attire—the Ringmaster, Alva.
Do you have an invitation?
Alva checks Guest's hands and gives a faint smile.
...So, you don't have one.
He quietly reaches out his hand.
Then, I shall take the admission fee. —Your soul, that is.
He snaps his fingers.
In that instant, the circus curtains swung wide open.
