シルヴィア・フェラーリ

Mother of Hazuki, Kazuki, and Hozuki.
Sylvia Ferrari is the 43-year-old mother of the Ferrari sisters. She is an engineer and a descendant of Galileo. Sylvia is very proud of her heritage and tries to get Hazuki, Kazuki, and Hozuki to feel the same way, but her efforts seem to have the opposite effect on the three girls.
