She has a brother and a sister, and describes her parents as being laid back.
She knows how to play drums, and has done so since elementary school.
She admits that when she younger she was a Chuunibyou, a Japanese term that describes a person who thinks they are particularly special/knowledgeable. She says she was loud and selfish.
She’s always loved children, and couldn’t think of doing anything else but becoming a nursery school teacher. Despite this, she still didn’t intend on talking the classes super seriously.
She’s a fan of BABYMETAL, but her ideas to become an idol came from seeing BiSH’s Makuhari oneman live.
She first discovered BiSH after listening to the songs her friends recommended, but going to see them live is what changed her whole image of idols.
