Ono was scouted by her former agency during elementary school, and during her first year of junior high school she appeared in a television advertisement for the Coca-Cola Company's Fanta called "3-nen S-gumi: Kurohige-sensei", but when her original office was subsequently closed, her activities were paused.
Before graduating from junior high school she was invited by a model who was her mother's friend, and later came back to the entertainment industry.
This broadens Ono's range of activities in the theatre, films and television dramas.

In 2014, Ono made her first leading drama role in Tenchu: Yami no Shioki Hito on the same network.
