Before we dive into the "new" phase of her career, let’s establish the baseline. Anna Oonishi was born in Kanagawa Prefecture. Like many junior idols, her entry into the entertainment world began in elementary school, scouted for her precocious charm and camera presence. Between the ages of 10 and 14, she was active in the chika aidoru (underground idol) scene, appearing in DVD gravure releases and promotional events.
During this "junior" period, Oonishi was known for a specific look: bright, energetic eyes, a petite frame, and a surprising vocal ability that her management company pushed in small live house concerts. While dozens of girls in her cohort were merely props for photographers, Oonishi studied acting and singing.
The turning point: By age 15, Oonishi began publicly distancing herself from the gravure side of the industry, rebranding her social media presence toward seiyuu auditions. This is where the "new" Anna Oonishi begins.

She reportedly enrolled in a rigorous voice acting academy run by a major agency (likely affiliated with Nippon Ichi or 81 Produce, though she is currently listed as freelance). Her "new" vocal range is notably deeper and more controlled than her junior idol squeaks—a sign of professional voice coaching.
