Personal Life

Growing up, YUKA had very laid-back parents who let her do whatever she pleased. However, she was jealous of other children her age who worried about their parents.

In high school she loved English, and went to Australia to study on an exchange for a month. She didn’t get along with her first host family, particularly the mother. When she left them, as a goodbye the host mother stuck her middle finger up at Yuka and said “fuck you”.

Before joining EMPiRE, YUKA was planning to attend university in Tokyo. She was already arranging to move during auditions as she didn't believe that she would actually pass the training camp. She later graduated EMPiRE so that she could attend university.
