The struggle to become number one in a Roppongi hostess club. Based on a story by Akira Eshima. In Roppongi’s “Papillon,” a popular cabaret club among many, there were two number one hostesses. One was Ayame, rumored to be a virgin, who meticulously attends to each customer. The other was Tsubaki, who was willing to engage in intimate business dealings, thereby attracting high-spending clients. Into such a “Papillon,” Yuri has just joined.
