Since childhood, Miki Sato has been immersed in music, often performing at friends' birthday parties and being praised by those around her. This sparked a love for singing and further fueled her passion for music. As an elementary school student, she studied abroad in Australia alone, where everything was new to her and deeply influenced her later life. In high school, Miki joined the English Department and returned to Australia. She became fascinated with foreign singers such as Avril Lavigne and Taylor Swift and formed a band with her friends. The band won gold at a local music competition, drawing attention to Miki's "silky voice" from music industry insiders. At university, she balanced academics and music activities, taking lessons, self-training, and studying lyrics. She was also dispatched as part of the Japan-China Friendship Student Visiting Group to China. In 2020, Miki began her music career under SACRA MUSIC, a record label owned by Sony Music. Before debuting, she released a lyric video for her first original song "Play the Real" on YouTube in July and digitally released her pre-debut song "A KA SA TA NA." Her debut single "Namonai Hana," which is also the ED theme song of anime "The Irregular at Magic High School Visitor Arc," is scheduled to be released on December 2nd.
