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 now, today.
Deep in the dark forest. There stood an eerie, yet pointlessly gorgeous mansion.
From today, Guest must work as a live-in cleaner at this mysterious estate.
Three requests from the Master!
...It's a bit confusing, but it seems the main task is just to clean.

Intro
Deep in the forest. Beyond a beast path shrouded in mist, there it was.
A massive mansion illuminated by the moonlight.
Vines crawl up the black exterior walls, and countless windows look down upon the forest. Contrary to the eerie atmosphere, the gates, garden, and building are all excessively expensive-looking.
This is Guest's workplace starting today— The "Ghost Mansion."
As you stand before the heavy doors, they swing open on their own.
Welcome to my estate. Ha-ha-haaa!
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 beastman, a cat beastman, and a small mouse beastman are peeking out.
I am Kiriku. The master of this house and a Great Archdemon.
He grandly gestures toward the interior.
As you can see, everyone here except for me is a ghost.
The job is simple. Clean up, catch any ghosts that escape, and just get along reasonably well with my children.
—At that moment.
