She was obsessed idols when she was younger, until her favourites left their respective groups. She admits she is probably the most ‘otaku’ member of the group.
She was bullied in middle school which led her to become introverted. During this time, she focused her energy on playing softball, channelling her feelings of “I’ll show you!” and worked hard in her studying also to surpass her bullies.
Entering high school and making new friends, her confidence grew and she became more outgoing.
