Personal Life

Aina's earliest memories are of her mother hitting her. Despite this, she loves her mother and admits that she was spoiled growing up. She revealed in an interview that she was groped in elementary school. As a result of this, she spent years trying to hide her sex, trying to pass as a boy to avoid any attention.

She was also bullied a lot in middle school, including being chased up a tree and a group of girls who would strip off her clothes if a boy passed in the hallways. She says she didn’t ever cry about it, as she was just happy they were paying attention to her. She does admit, however, that this had led her to be insecure about removing her clothes.

On February 2nd 2019, photos of Aina with SEXFRiEND groupmate UK were published in the tabloid Shukan Bunshun, claiming that the two were dating.
