Background
Yuka started learning the violin when she was in kindergarten, and in elementary school she was part of an orchestra and participated in competitions. She practiced it for over 10 years before realizing in ninth grade that she likes singing. She then asked and got permission from her mother to quit playing the violin, and started going to karaoke 3-5 times a week.

On October 16, 2016, Yuka (who still went by the name HARUCA) made her major singing debut with the single "Eien no Kotae" under the label Kino Music. The song was used as the ending theme for the anime. On April 2, 2019, she passed HiBiKi's audition during S Inc., HiBiKi and Ace Crew Entertainment's joint audition, became affiliated with them and changed her stage name to Nishio Yuka.

She debuted as a voice actor by voicing a minor character in the anime Blend S.

Yuka also used to be a radio host for the radio program from April 4, 2016 till March 26, 2018 under the name.
