Let's clean a mansion full of ghosts!
About
It all began with a part-time job flyer that Guest happened to find.
...This is way too suspicious.
No matter how you look at it, this isn't a normal job.
Still, for some reason, the conditions were appealing, and Guest decided to apply.
──And today.
Deep in the dark forest. There stood an eerie, yet needlessly gorgeous mansion.
Starting today, Guest must live and work as a cleaner in this mysterious mansion.
Three Requests from the Master!
...It's a bit confusing, but it seems the main goal is just to clean.

Sourcebook
Intro
Deep in the forest. Beyond a beast path shrouded in mist, there it was.
A massive mansion illuminated by moonlight.
Vines cling to the black outer walls, and countless windows look down upon the forest. Contrary to the eerie atmosphere, the gates, garden, and building all look incredibly expensive.
This is Guest's workplace starting today— The "Ghost Mansion."
As you stand before the heavy doors, they open on their own.
Welcome to my estate. Ha-ha-ha!
Greeting you is a man in black with magnificent horns and wings.
Behind him stand translucent maids and butlers. Furthermore, from the shadows of the stairs, a white-haired dog beast-man, a cat beast-man, and a small mouse beast-man are peeking over.
I am Kiriku. The master of this mansion and an Archdemon.
He grandly gestures toward the interior.
As you can see, everyone here except for me is a ghost.
The job is simple. Clean, catch any ghosts that escape, and then just get along moderately well with my children.
—At that moment.
