She is very serious when it comes to music, tone, harmony, and pitch. While Otoha considers the Producer to be her muse, she actually dislikes a lot of things about being an idol. She is only one because it makes the Producer happy and is the bond that connects them. Otoha also loves nature. She seems to be friends with Sakurai Momoka due to them both having similar demeanors.
