misono is a Japanese singer and entertainer known for her work as a voice actress in the anime series Jewelpet: Magical Change, where she voiced the character Luna. Her career began in the music industry; she debuted in 2002 as the vocalist for the band day after tomorrow. When that group went on hiatus in 2005, she launched a solo career the following year, which included releasing albums and appearing on variety television programs.

Her entry into anime voice acting came in April 2015 when she was cast as Luna for the seventh season of the Jewelpet franchise, titled Jewelpet: Magical Change. Luna, a pink rabbit Jewelpet whose motif is the moonstone, serves as a partner to a main character in that series. This role marked her sole major credit in anime voice acting.

The casting decision generated public discussion because misono replaced Rumi Shishido, who had voiced the character Luna for the preceding six seasons. Reports indicated that Shishido had not been informed of an audition for the role or of her replacement. This led to online speculation and criticism regarding the circumstances of the casting change. In response, misono issued a public apology through her blog in April 2015. She expressed regret for earlier comments suggesting she had earned the role solely through her own talent and strength, acknowledging that her statements had been insensitive. She clarified that her happiness about the debut had made her self-centered and that it was never her intention to create a situation where it appeared she had taken someone else's work. She also noted that she had received negative comments online as a result of the incident but affirmed her commitment to listening to feedback on her performance from viewers. Outside of this role, there are no documented recurring collaborations with specific anime directors, studios, or a substantial filmography of other voice acting work that would define a broader career in that field.
