――No road back, but a hundred paths for love.

Clang, Clong.
Breaking a slumber of decades, the Bell of Welcoming tolls.
Flowers bloom, lanterns light up, and the hundred demons stir.
「――The Marebito has arrived!」
To see the Marebito, just for a moment.
And if fate allows, to take that hand as my own.

This is the capital of yokai, severed from the laws of the living world,
Vermilion torii gates and glamorous pleasure districts.
Mermaids swimming in canals, tengu crossing the sky,
and mysterious shops lining the streets.
...Into this Hanagasumikyo, for the first time in decades, a human girl has wandered. The yokai call her the "Marebito," welcoming her as a sacred guest.

Prepared for her is the magnificent Bride's Palace. Fox women attend to her every need with devoted care, and the whole city celebrates her arrival.
... However, there is one thing.
Even so, the yokai of Hanagasumikyo are smiling.
For them, this is not a tragedy, but a long-awaited joyous occasion.
A welcoming festival to celebrate the Marebito.
And another festival.
Its name is the Hyakki Marriage Festival.
Yokai maidens of different species and status all woo the lone Marebito— a glamorous and slightly rowdy festival of love.
Though suitors are many, the Marebito is free to choose.
Whether to love just one, to face multiple hearts,
or to choose no one at all.

Now then, which of these spirits shall capture the bride's heart?
"Oh my... you're declining my invitation? Humans really don't know their place, do they?"
Coral hair and jade eyes. A magnificent mermaid artist. Her poems strike the hearts of many, and her paintings enchant all who see them.
However, as for her personality... it's quite difficult.
Behind her elegant smile lies a sharp, poisonous tongue. While she sublimates the ugly emotions of others into beautiful art, she never admits to her own ugliness.
A mermaid princess who believes she deserves to be loved learns of a love that won't go her way for the first time.
Will that arrogant love truly become a beautiful poem?
"Seriously!? You'll go out with me!? Yay! I'll go get ready right now!!"
Golden hair and red-and-white horns. An oni princess dressed in robes shimmering with gold thread. She is quick-witted and a bit selfish. A charming youngest daughter who grew up doted on by her brothers.
She is perfectly bold when dealing with men. However, the moment she's in front of a girl, she suddenly loses her way.
Let alone when she's in front of her beloved Marebito; her usual light talk vanishes. ...Even so, she isn't a princess who gives up on what she wants.
The oni princess, inexperienced in love, tries her best to act grown-up today.
"Hahaha! It is well, it is well! As long as you are by my side, you have nothing to fear!"
Flashing her black and vermilion robes, she is a tengu warrior who soars through the capital's skies.
Boisterous and cheerful, she has a deep sense of duty and compassion, unable to leave those in trouble alone. As the squad leader of the Tengu Corps, she leads her subordinates and protects the peace of the city.
One might say she's straightforward in love too... but surprisingly, it's not that simple.
Though she realizes her own feelings sooner than anyone, it is precisely because she values her beloved's freedom that she keeps them hidden in her heart.
Hiding a secret affection behind that most reliable back.
"...Hehe. If you look at me like that, even I might start getting greedy."
Wisteria-colored robes and a graceful smile: the Jorogumo.
A skilled tailor who runs the high-end kimono shop "Kasane-ya" all by herself. She dearly loves beautiful women and beautiful clothes.
A mature woman who has known love and partings many times, yet still enjoys the act of falling in love.
Sweet words and touching fingertips are perfectly natural expressions of affection for her.
However, this spider woman of many loves might find herself slightly thrown off balance this time.
What kind of love will the woman who knows love inside and out teach the Marebito?
