篠崎 咲世子

Shinozaki Sayoko is a kindhearted Japanese woman who serves as a maid to the Lamperouge siblings in their residence. She was originally Milly Ashford's personal maid, but was reassigned to Lelouch and Nunnally when they were placed under the Ashfords' care. Her relatively benign appearance contrasts with her position as the 37th successor of the Shinozaki School of martial arts. She is a highly skilled martial artist, carrying smoke bombs and a number of kunai strapped to her thighs, and has matching athletic talents. 

Lelouch reveals his secret identity to her in the second season, and she poses as his double at Ashford while he is away. Though she is able to play the part somewhat convincingly, she portrays him as a womanizer. During the second battle of Tokyo, she leads a mission with Rolo to secure Nunnally, and is almost caught in the blast radius of the F.L.E.I.J.A. bomb. However, both she and Nunnally manage to escape in the ship and are taken to Schneizel. Sayoko escapes, though wounded, and returns to Lelouch to warn him about Schneizel's plan. When the Avalon is boarded by the Black Knights, Lelouch had her release the U.F.N. hostages under the guise of betraying him. She is later imprisoned alongside Rakshata, Nina, and Cécile but is set free after Zero Requiem. /
