Tsukimi is a light-skinned young woman of average height and build. She has dark hair worn in a bob haircut with a fringe. Like her teammates', her uniform emulates a basic tracksuit style, combining a high-collared, zipped sweater with a single white line running along its sleeves with darker pants and a black undershirt (maroon in the anime). Border's logo is located on the outer side of both sleeves, roughly around the half point of the humerus.
As a B-rank agent, Tsukimi should be individually more powerful than C-rank trainees. Her unit is strong at standard tactics. However, all three members were single-handedly taken down by Yūma before they could show their true capabilities.
Hanao shares her surname with Ren Tsukimi. Their family information from Border Briefing File is also compatible, with Ren having a younger sister listed and Hanao an older one. However, any blood tie between the two remains unconfirmed.
