"Whether it's Kinshicho or another world - I'll be No. 1!!"

Club Cool J is a cabaret club located in the entertainment district of Kinshicho, Tokyo. Chikage, the No. 3 hostess, was struggling to become the No. 1 hostess. Kinshicho has a wide range of customers, and there are many troublesome customers. Chikage reprimands a customer who is trying to sexually harass her and makes him her own customer, leading to an argument with Suzune, her number one hostess.

As the battle between the women, who refuse to yield to each other, is going on, the store's circuit breaker suddenly goes off, creating an uproar in the store.

When the door opens... the whole shop is transported into another world!? While panicking, Chikage makes up her mind and opens a cabaret club in another world...!?
