A 2006 interview published by Anime Times, while she was still a student, records her weekly routine: lessons three days a week (Monday, Wednesday, and Friday at midday) followed on some days by part-time work, plus daily practice of stretching and articulation at home and written notes on documentaries and drama she watched at her instructor's suggestion.[4](https://www.seimaga.jp/animatetimes23/) In the same interview she described her goal as becoming "the one and only actor of myself" rather than simply the best.[4](https://www.seimaga.jp/animatetimes23/)
Her credited screen work begins around 2010, with early television anime roles including Akane in *Naruto: Shippuden* and a mother in *Steins;Gate*.[1](https://www.artsvision.co.jp/talent/14248/)
