She is the proprietress of "Tomon Inn," which serves as a saloon she is also a performer who performs in front of her loyal patrons. Though she may look like a refine lady who seems to be defenseless she is actually tough and a shrewd business woman who is always in the company of her two bouncers who serves both as her bodyguards and enforcers.
