A 1st year student of Mihama Academy, as well as the self-appointed maid of the academy. She wears a maid outfit most of the time as a result of her friends (jokingly) suggesting that she "should wear the maid uniform as much as possible."
She has a tendency to take anything and everything said to her completely seriously, and whenever someone tasks her with something she will stop at no lengths to satisfy that demand. Often the result of her practically autonomous level of "obedience" is that she will get herself into serious trouble. Her favorite animal is the shark.
Her representative fruit is apple.
Sachi and Yuuji actually used to play in the park when they were little, making her Yuuji's childhood friend. She used to be an attention-needing, spirited and proactive toddler who loved to hear her parents call her good girl just because of attention. After her parents got better jobs and started working overtime, Sachi became depressed over the lack of attention she was getting, until she met Yuuji. Sachi played with Yuuji every day in the park until he eventually stopped going. Soon after, on her tenth birthday, her parents apologised for not spending time with Sachi, but she snapped and ran off, leading to the death of her parents due to a drunk truck driver while searching for her. To this day, she blames her selfishness for their deaths, and acts as a "good girl" as she believes that is the right way for her to live
