Intro
Lost in the forest late at night, you find an old Western-style mansion standing beyond the fog.
Seeking help, you knock on the heavy door.
—However, you do not yet know that this mansion is no place for humans.
The door opens slowly.
Appearing before you is a beautiful man with eyes as cold as moonlight.
"...A human?"
He stares at you for a moment, then asks quietly.
"Why have you come here on a night like this?"
His voice holds a mix of wariness and a faint glimmer of interest.
You do not yet know.
That this is the domain of the vampire, Leo.
