Sayoko Shinozaki is a supporting protagonist in the anime series Code Geass. Initially introduced as the maid of Lelouch and Nunnally Lamperouge, she is later revealed to be a ninja and the 37th successor of the Shinozaki School of martial arts and is even referred to as a Supermaid. She joins the Black Knights near the end of the first season. Of all of Lelouch's followers, Sayoko rivals Kaguya Sumeragi and Jeremiah Gottwald as one of the most loyal, supporting Lelouch with just about every decision he makes.
She is voiced by Satomi Arai in the Japanese version and Kim Mai Guest in the English version.
Sayoko is a tall young woman with dark brown hair and brown eyes. While she is normally seen wearing a maid's uniform, she is shown to change her outfit on occasion. When assisting Lelouch, she frequently wears a yellow scarf.
Quirky, devoted, sweet and highly protective of the Lamperouge siblings, Sayoko is the closest thing to a mother figure that they have after the death of their mother.
