Her regular dubbing assignments also include the work of actresses Zhang Ziyi, Jun Ji-hyun, and Leighton Meester.

Beyond her work in film and anime, Yumiba has also lent her voice to video games, such as the role of Rinza in Tenchu 4 and the character Seawasp Yunica in Gravity Rush. She is formally certified in Japanese dance, holding a stage name in the traditional Hanayagi school.
