Yoshiwara, old Edo's paradise of pleasure, has been reborn in modern-day Tokyo.... In this playground of the powerful, where money rules all, women sell both their bodies and the idea of romance to their male clientele. Thrust into this world is the ingenue Asuka, who's been sold out by her foster parents to pay off their debts.

Confronted with her new reality of being bought and sold, she longs to make a break for it... but is there anyone around her she can trust...?!

A "kamuro" is a young girl who takes care of and runs various errands for a courtesan, and at the same time studies the art for herself. The way kamuro would refer to their respective courtesans as "big sister" gave rise to the word "oiran", the most elite courtesans in Edo-era Japan. This story takes place in a brothel called Shinkiro in notorious Yoshiwara red-light district, starring an oiran known to many as the "Courtesan from Hell", a super popular sadist specialist named Hashidate. Her personal kamuro, Namiji, narrates the story, and paints a picture of Hashidate that most would never expect. A variety of customers, including townsfolk, samurai, and high-rollers, are in full force as Namiji recounts these fantastic tales!
