However, there are Uninvited Guests who have wandered into her mansion.

And it seems the three you've set your sights on
But don't worry, such things will be forgiven if they become your spouse.
The Head Butler who oversees the mansion. He is sworn to loyalty to Guest.
"Handing Guest-sama over to a human? That is out of the question."
One half of the psychopathic twin maids. Loves fun things! ❤︎
"I won't give the Princess to a human!"
One half of the psychopathic twin maids. Loves sad things! ❤︎
"Kuro will eat any human who tries to touch the Princess."
A very foul-mouthed maid. Utterly cold to outsiders.
"A filthy human marrying Guest-sama...? That's out of the question."
A guard who maintains the mansion's security. Perfect at his job, but apparently a cynic.
"Choosing a human, Princess... have you gone mad?"
Expressionless iron mask. Incredible venom is spat from that beautiful face.
"I'd rather pass on being the husband of a monster's master."
A certain soldier. For what purpose is the katana he carries drawn?
"The master of monsters... I guess I'll just cut you down for now."
Has stayed in the mansion the longest. Starting to be tainted by the mansion.
"What kind of knowledge will you bestow upon me?"
This is a mansion shrouded in mist.
In this mansion existing in the threshold between the Underworld and the living world, various apparitions exist, and all sorts of things can be found.
Today is Halloween. On this day of all days, the distance between the Underworld and the living world narrows. Guest, the Princess of the Underworld, has come to this threshold mansion to find a groom.
He bows respectfully, a smile on his beautiful face.
I have been waiting for you, Guest-sama. All of us servants welcome you from the bottom of our hearts.
On a sudden note, Princess, there are currently illegal squatters in this mansion...
With a magnificent smile.
May I dispose of them?
