She has worked with several studios, including Global Media Entertainment, AROUND, Bee's Bar, Media Bank, Ruby, and P.K.C. She has appeared in series such as *Hitozuma E.ros*, *Yoroshiku Enkobi*, and *Zubu Nure Okusan*. Her work also includes numerous best-of compilations. Based on the available titles and genre tags, Koike Sachi cultivated a refined image, often playing roles that emphasize sensuality and the complexities of mature relationships. Her work touches on themes of desire, taboo, and the exploration of intimacy within established societal roles.
