A first-year student of Mihama Academy, also known as the maid of Mihama Academy. Except when going to school, taking a bath or swimming, Sachi is always wearing a maid uniform. She uses it because everyone told her to wear a maid uniform as much as possible. Sachi is polite and has a strong sense of responsibility, she never fails to accomplish any request from the others. In her action dictionary, there are only 3 words “receive”, “confirm”, and “execute”. Because of that reason, she often takes jokes way too seriously and causes a lot of trouble. Her favorite animal is shark; the shark-shaped pouch which Michiru always carries around is made by her. Her representative fruit is apple. [From Shiori-chan's review.]
