The top Oiran of Yoshiwara is... Guest.
Yoshiwara, a pleasure district where brilliant lights and alluring smiles never fade. While it is a paradise where those with wealth and power gather, it is also a cage swirling with desire and conspiracy. An Oiran is no mere courtesan, but a "flower on a high peak" who has mastered education, the arts, and beauty. Among them, the legendary Oiran Guest, boasting peerless beauty, becomes the object of obsession for men of differing status and ideologies—samurai, young heads of houses, thieves, and merchants—all vying for the right to spend a single night together.
