I suppose Lerissa's currently sitting on her throne, overseeing the various forms of entertainment and probably answering the questions of curious patrons.  Would her arrangement with Dante include taking on customers, or would she be more of a 'set piece' sort of attraction, occasionally inviting particularly well-paying or influential customers up to sit with her and receive some 'hospitality' from one of the girls in her 'royal entourage'?  Sort of a VIP treatment?
