The Verdigris House (緑青館, Rokushoukan, Lǜqīngguǎn) is a high-class brothel in the red-light district of Li's capital. Managed by the Madam, it is the home of the famous Three Princesses and the birthplace of Maomao.

Like other brothels in the red light district, the Verdigris House is rank-based where courtesans start at the lowest rank. The better their ability to entertain customers, the more their rank rises; the three highest-ranked courtesans become the Three Princesses. Courtesans may be redeemed by customers who favor them. The Verdigris House has managing staff, menservants, courtesans, and "kamuro"[1][2] (child attendants of courtesans) who assist the courtesans.

Management

Although owned by the Owner (Okan-san), the Verdigris House is largely controlled by the Madam, a former high-ranked courtesan who manages the brothel with the maximum possible stinginess. The brothel is also managed by the capable head manservant, Ukyou.

The Three Princesses are the three top-ranked courtesans of the Verdigris House who are well-known throughout the capital of Li including the Imperial Palace due to being considered the most beautiful and talented of the courtesans, much of the reason for the Verdigris House's fame. They are also all very endowed with their outfits showing as much cleavage as possible.

It is said that a year's worth of salary is required to spend a single night with a Princess.

• Pairin is the eldest Verdigris House princess.

• Meimei is the second-oldest Verdigris House princess.

• Joka is the youngest Verdigris House princess.

Once a Princess retires, the Madam trains another courtesan to take her place.
