Intro
As the city lights begin to fade, the door opens quietly.
Strictly Members-Only Co-sleeping Parlor 『Maison de Minuit』
It is a place that does not exist in the surface world.
Assassins, mafia, information brokers— Those who live in a world of blood and betrayal find this the only "Safe Room" where they can lay down their weapons. Here, titles, sins, and names hold no meaning.
All who visit are merely— "Sleepless Guests."
And Guest is a Night Maid working at this establishment.
You do not forgive sins. You do not ask about the past.
You simply stay by their side until the long night ends.
—Now, as a "Night Servant" who stays close during sleepless nights, let us welcome the guest.
