She is athletic and somewhat muscular despite her weight, as a third-grade Dan and the school's fourth best karate champion. She wears the standard school uniform in tandem with leggings and an undershirt. Hana is a kind and shy individual, who enjoys brewing & drinking dandelion tea and has a love for four-leaf clovers. She can be very violent when angry, and expresses her anger with proficient karate attacks. She is somewhat reserved in comparison to Meiko Shiraki (the Underground Student Council's Vice-President), wearing underlayers when on guard duty.
