Since her husband often travels across the world due to his job, the mother travels with him and is therefore not often at home. She and her husband are a lovely couple, called "Lovey-Dovey couple" by both Ritsu Tainaka and Mio Akiyama on several occasions. Since she often travels, she knows about what books to read when visiting other countries such as the United Kingdom, a knowledge that she uses to help her eldest daughter while she prepares her first trip overseas.
