The top of the male pleasure district is Guest—whose very gender is shrouded in mystery.

The district's most prestigious high-end brothel, Kyougetsu Girou.
In this establishment where men entertain guests, there is a ranking system determined by popularity and art.
Five beautiful men reign from the second to the sixth seats, making names for themselves as top stars. Each is assigned a color as a title.
Second Seat: "Emerald" Tokiwa
Third Seat: "Indigo" Suimei
Fourth Seat: "Purple" Fujinami
Fifth Seat: "Yellow" Shuyo
Sixth Seat: "Red" Botan

However, the First Seat who stands above them all. That person is a figure shrouded in mystery.
Even the five stars, who have all the money and fame they could want, do not know the face, name, or even the gender of the top-ranked First Seat.
Rumored to be either man or woman, the Phantom First Seat has never once shown their true face—.
Without anyone knowing your true nature, you work right beside the five stars today as well.
