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)
