Mizuki Asahina

A rather humble and pretty girl the sister of Azusa. She owns the Silver Star Tea House and cleans it daily even though not many customers drop by. A slight depression set into her after Azusa had left leaving her feeling empty inside and even had a reoccurring nightmare of the day Hiruko came into the tea house to replace Azusa. However she covers it up as if nothing had happened and shows a great deal of friendliness toward her few customers as well as Hiruko and even pleasantly puts up with Hifumi. Source: Wikipedia
