Some of her earlier roles are her voice acting debut as Tsubaki Sakura in Kare Kano, Kitsune no Akane in Angel Tales, and Elliot Chapman in Sci-Fi Harry.
Saeko was famed for her long, straight, black hair and seemingly cold outward appearance which led to her being cast in various tsundere and 'cool-girl' roles.
She then cut her hair short in the spring of 2005, which strangely coincided with the increasing diversity of her roles, as Saeko herself noted on the My-HiME fandisc interview.
Saeko has pursued a singing career with Yuki Kajiura, who wrote music for some of the Nanshō stage shows, writing and producing almost all her material.
Originally recording and performing as 'Saeko Chiba & Yuuka Nanri' for Memories Off 2nd, the duo released three singles and an album before breaking up on March 6, 2005.
