Yume Nozaki is a Japanese voice actress and former idol, born on November 15, 2007, in Aichi Prefecture. Her career began in the entertainment industry as a member of the idol group Sakura Gakuin. This experience as a performer preceded her transition into voice acting for anime.

Nozaki is primarily known for her debut and most prominent role to date as Tsutsuji in the original 2022 anime television series Onipan!. Tsutsuji is characterized as a cheerful and curious 14-year-old red oni girl who transfers from Onigashima to a middle school in Tokyo with the goal of improving the image of oni in a world where they coexist with humans. This role marked her entry into the anime voice acting industry and is her sole widely documented voice performance.

For the Onipan! project, Nozaki collaborated closely with her co-stars Mika Negishi and Kokona Nonaka, who are also former members of Sakura Gakuin. Together, they formed a musical unit called Onipanzu! specifically for the series. As part of this unit, Nozaki performed the anime's opening theme song "Onipapapan! Pan!" and the second theme song "Oni Yaba—!" alongside Negishi and Nonaka. Her involvement in the series extended to participating in interviews to discuss her character and the show's themes, where she shared insights on playing a character seeking mutual understanding between different groups.
