Miku Sasao is a Japanese singer-songwriter and voice actress from Kushiro, Hokkaido, born on September 18, 1980. She began her career in the music industry, making her debut in 2007 with the album Tulip no Applique. Her entry into voice acting came in 2008 when she was cast for the role of the street musician YASUKO in the television anime series Someday's Dreamers II Sora, also known as Mahoutsukai ni Taisetsu na Koto -Natsu no Sora-. For this role, she performed under the character's name, YASUKO, as well as the alias micc. In addition to providing the voice for YASUKO, she performed the series' ending theme song and the insert songs sung by her character within the story. This voice acting role remains her most prominent and frequently cited credit in animation. Beyond this project, there are no widely documented records of her taking on other significant or recurring roles in anime, indicating that voice acting was not the primary focus of her career. Her professional activities have remained largely centered on her music, where she continues to perform and release new work.
