She stopped going to high school around the 3rd year and spent her days at home, doing nothing. At the time, she didn’t want to be around people, and lost sight of her reason to live. Because of this, she failed to pass the college entrance exams and had to go to a prep school every day. Her plan was to go to a pharmaceutical school, to later become a Pharmacist as the job would be stable and pays well. [x]
She has mentioned during the Reformed BiS 2016 audition, and in other interviews, that she is bisexual. However she doesn’t want to rely on this to make her unique. [x] During BiS’s appearance on 矢口真里の火曜The NIGHT#22 on September 6, 2016, Aya Eightprince told a story from the audition. They deliberately didn’t mention any names, but they spoke about one of the candidates, a bisexual girl, who came onto Aya Eightprince one night. The girl spoke to Aya about her sexuality, how she likes men and woman, and then asked Aya if she wanted to try anything with her. At this time, Yuuka was a part of SiS, which may be why they didn’t say a name, or even describe the person they were talking about [x]
She originally auditioned for BiSH after seeing about the audition on Twitter. At first she didn’t feel like applying, but at some point she felt compelled to apply. She went to the interview in Osaka, and was in a team alongside Go Zeela. She didn’t expect to pass as there were lots of idol-like girls there. After not making the cut, she was later invited back to take part in the reformation of BiS training camp audition. After not being successful yet again, she was later placed in SiS before the group was merged with GANG PARADE. [x]
Starting November 20, 2018, Yuuka has started to write her very own weekly movie review for the online publication Storywriter.
