She is always seen wearing a school uniform and with her waist length hair in a unique Oriental hairstyle with a intricate Japanese hairpin with a poppy on the end holding it up; she is known as Forever Flat.
Haruna, when not on duty, acts like other girls her age. She is clumsy, particularly due to her choice of footwear, which she refers to as her own style; she gets embarrassed when something lewd happens to her, such as when Maria L. Sherlock fell between her thighs; and is afraid of snakes. Like many people from the boondocks of the 11th Hierarchical City of Remnant, she is intimidated and somewhat impaired by technology, such as when the vending machine she uses goes haywire after stuffing an entire ¥10,000 into it.
Haruna also does not like the idea on having to converse with someone who is a foreigner using the foreigner's native language, opting that she would rather have them converse in other tongues. Indeed, Chiaki Kondō describes her way of speaking Japanese as strange, and is referenced as a mix of Japanese polite honorifics and rude words, and is thought by Sumiye Egnell as someone who has learned Japanese from talking mostly to detectives or police officers.
