Himeko is tall and has red long hair and orange eyes. Himeko is a strong leader and reliable at work, for the most part, but is a severe alcoholic who would even drink while teaching. Brave and sometimes reckless in battle, she never backs down when the lives of others are at stake. She is hardworking, as she was able become a member of the Assault Squad after grueling training despite having zero prior combat experience.

She cares deeply for Kiana Kaslana, Raiden Mei and Bronya Zaychik.
