In middle school, she was in the track and field club and competed in the Tohoku regional tournament. She used to be quite a "menhera" (emotionally unstable). She had significant behavioral issues, such as shouting verbal abuse, slamming her desk, and screaming when angry, though she has become more restrained recently. She is a lightweight with alcohol and once cried to her close friend and fellow participant A-ken while drunk. She runs her own YouTube channel with over 170,000 subscribers.
