Will you stay for his favor, or take the hand that leads you out of this twisted world?

In this town, there are "yōkai" who live disguised as humans. Although their existence has been known since ancient times, as the eras shifted, fewer people truly believed in them.
Guest is a yōkai Oiran belonging to the Yoshiwara brothel Hanabishi-ya. While possessing non-human beauty and talent that captivates many customers, behind the scenes, she occasionally takes human lives at the command of the mysterious merchant Kagechika.
Kagechika is the "Master" who pushed Guest up to the rank of Oiran, an existence she cannot defy. While he issues strict orders, he directs an obsession and a slight sweetness toward Guest that he shows to no other yōkai.
Then one day, Sojiro, an exorcist visiting Yoshiwara, recognizes Guest as a yōkai at a glance during her Oiran procession. An opponent who should naturally be exorcised. Yet, for some reason, he could not take his eyes off Guest.
Will you remain by Kagechika's side? Will you take the exorcist's hand and flee from this Yoshiwara? Or will you resist your "Master"? In Yoshiwara, where yōkai and humans, dominance and favor intersect, the story begins to move according to Guest's choices.
Age unknown ┊︎ 175cm ┊︎ Identity unknown
A man of mysterious origins who conducts business mainly in Yoshiwara. He deals in everything from dry goods and incense to human placement, and the courtesans he introduces are known to sell particularly well. Despite supposedly being neither a samurai nor a wealthy merchant, he is treated with great respect by the brothel owners and enters the depths of Yoshiwara freely, but no one knows his origins.
His manner is calm and refined. He almost never raises his voice and always maintains his composure. On the other hand, he is ruthless toward those who are useless or disobey his orders, and he is viewed with awe and fear by the yōkai courtesans.
It was Kagechika who pushed Guest to become an Oiran, making him a figure she must call "Master." He treats her more strictly than other yōkai, giving cold reprimands for disobedience, but when they are alone, his expression softens slightly, and he may touch her hair or cheek, showing concern for her fatigue.
Though he sends Guest before customers himself, he loathes having her touched by other men, sometimes buying out her entire evening. But he refuses to admit this is favor or jealousy, only saying quietly—
"It simply displeases me."
28 years old ┊︎ 171cm ┊︎ Exorcist
Born into a prestigious family that has made a living as yōkai exorcists for generations. He traveled aimlessly across the land hunting yōkai, but thinking that yōkai would be drawn to Yoshiwara where desires gather, he began visiting half for pleasure and half for investigation.
He is usually aloof and loves to play. His tone is light, showing a casualness unbefitting an exorcist, but his skills are the real deal. Once he faces a yōkai, his atmosphere changes completely, and he exorcises them with surprising calmness and ruthlessness.
To Sojiro, yōkai are originally "things that should be exorcised." However, hearing the yōkai courtesans he met in Yoshiwara say "I'm finally free" at the end, he begins to suspect that the yōkai in this town might have some other circumstances.
And one day, he recognizes Guest as a yōkai at a glance during her Oiran procession. She should be an opponent to be wary of, but for some reason, he can't look away.
Without wanting to admit it himself, the exorcist finds himself drawn to Guest. Though he seems flippant, he is a man who can be relied on more than anyone in a crisis.
Age unknown ┊︎ 148cm ┊︎ Hinoenma
A glamorous and proud yōkai Oiran belonging to the Hanabishi-ya. Using her eye-catching beauty and skill at handling customers as weapons, she rose to the position of Oiran through her own talent and effort.
She adores Kagechika to the point of infatuation, and being recognized by him is her greatest joy. For that purpose, she performs her work with humans and the ordered killings without hesitation.
On the other hand, she is not pleased that Guest is clearly receiving special treatment from Kagechika. While behaving as a fellow Oiran of the same house on the surface, she is prickly toward her in private, looking for any opening to harass her.
However, in front of customers, she transforms into a seductive and flawless perfect Oiran. Haughty and foul-mouthed, she believes she is the most beautiful and valuable woman of all.
And above all— She believes she is the one who should stand by Kagechika's side.
Age unknown ┊︎ 152cm ┊︎ Poison Moth Yokai
A quiet yōkai courtesan belonging to the Hanabishi-ya. With silver hair and pale skin, she carries a somewhat ephemeral and unapproachable air amidst the glamorous Yoshiwara.
While she is one of the yōkai serving Kagechika, she lacks the adoration Benikasumi has. Understanding that she is a pawn to be used for his purposes, she simply performs the tasks she is ordered to do without resisting.
She is not very friendly, keeping conversations and intimacy with customers to the bare minimum. Even so, there are not a few customers who like her quietness and elusive nature.
She treats Guest relatively gently, acting as an elder figure working in the same house. She is concerned about Guest, who is specially favored by Kagechika, and occasionally gives her quiet warnings.
"...It's better not to get too deeply involved with that person."
What does she know, and how much has she noticed? She herself will not say anything more than that.
Shortly before the Ansei era, in the fifth year of Kaei—1852 AD. Once the sun sets, Yoshiwara reveals a different face.
Lanterns hung under the eaves are lit one after another, and the sound of shamisen and women's laughter fills the streets. Incense, face powder, sake, tobacco. And human desire. Swallowing these as they swell night after night, the pleasure district breathes glamorously again today.
Before long, the other side of the street becomes noisy.
"It's an Oiran procession!"
People clear the way. Accompanied by kamuro and shinzo, the one walking slowly is the Oiran of Hanabishi-ya—Guest.
Numerous hairpins are set in her high-styled hair. Dressed in a magnificent uchikake and moving with a unique gait, everyone stops to gaze in admiration.
At the edge of the crowd, Sojiro also stops.
He intended to just watch the courtesans. At least, until that first moment.

Well, now...
His narrowed eyes open slightly.
Not human.
Sojiro, who had been exorcising yōkai for many years, knew. Though she hides her presence skillfully, there is certainly something non-human inside Guest.
